Sunday January 22 2023 Forecast (8:53AM)

DAYS 1-5 (JANUARY 22-26)

As stated previously, I mentioned that for areas I thought may have measurable frozen precipitation that a final call would appear on Sunday morning’s blog post, and that will follow just below. I’ve made a slight adjustment southeastward on the forecast storm track, expecting the low center to pass over the outer portion of Cape Cod or the Islands Monday. The center will also be elongated, and a little westward extension of low pressure as it moves away will allow the precipitation to hang on a little longer, allowing colder air in with enough time for a swath of snow across much of the region, after a mainly rain event for a good portion of it from tonight into early Monday. But enough snow will fall for the need of some removal activity especially northwest of a Boston-Providence line. After that system moves out, we get a dry interlude for Tuesday before the next system heads in for Wednesday into part of Thursday. This system continues to present as a snow to rain event for the region, with snow hanging on longest the further west and north of Boston you go. Details on this system will be worked out over the next couple days.

TODAY: Cloudy. Patchy afternoon drizzle / snow grains. Highs 35-42. Wind variable becoming SE to S up to 10 MPH.

TONIGHT: Overcast. Precipitation arrives quickly from southwest to northeast as snow in southwestern NH and north central MA where it transitions to a mix of snow/sleet/rain overnight, a brief period of snow and/or sleet inside I-495 before going to rain, and just rain elsewhere. Lows 32-39. Wind E 5-15 MPH, higher gusts along the coast overnight.

MONDAY: Overcast. Steadiest rain early morning but may still be mixed with sleet and snow in southwestern NH and north central MA, then tapering to occasional rain/drizzle except some snow/sleet mix potential continuing in aforementioned areas to the northwest, then precipitation becoming steady again west northwest to east southeast midday on, mainly as snow, but starting as rain/mix before transitioning to snow further south. Expected snowfall accumulation: 4-8 inches interior southern NH and north central MA with isolated amounts of greater than 8 inches possible in the highest elevations, 2-4 inches NH Seacoast down I-495 belt to I-90 region, 1/2 to 2 inches I-95 corridor, under 1/2 inch southeast of I-95 to little or nothing along the South Coast. Highs 33-40 except over 40 South Coast. Wind NE to N 10-20 MPH, strongest near the coast where higher gusts are possible.

MONDAY NIGHT: Evening snow showers possible especially eastern and southern areas, otherwise breaking clouds. Lows 22-29. Wind W 10-20 MPH, gusty.

TUESDAY: Partly sunny. Highs 33-40. Wind NW 10-20 MPH, gusty.

TUESDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

WEDNESDAY: Clouding over. Snow inland / mix coast by late in the day. Highs 33-40. Wind NE 5-15 MPH.

WEDNESDAY NIGHT: Overcast with snow/mix transitioning to mix/rain. Temperatures steady or rising slightly. Wind E-SE 10-20 MPH, higher gusts.

THURSDAY: Overcast with rain likely in the morning, possible mix far northwestern areas. Breaking clouds afternoon. Highs 36-43. Wind variable 5-15 MPH becoming NW 10-20 MPH.

DAYS 6-10 (JANUARY 27-31)

Trend to more seasonable cold. Watching for a disturbance with minor precipitation event – probably just a frontal passage – during the first part of the period and eyeing a more formidable low pressure impact potential around January 30, but the latter event is highly uncertain.

DAYS 11-15 (FEBRUARY 1-5)

Pattern trends colder. Watching a system for around February 2-3 with winter storm potential.

Saturday January 21 2023 Forecast (8:04AM)

DAYS 1-5 (JANUARY 21-25)

A fair weather interlude is ours today, though the day starts with lots of clouds before we finally break into some sun. But as you have been hearing, we’re in an active weather pattern and the next low pressure system is heading out way. While we end up cloudy on Sunday, most of the next system’s precipitation holds off until after daylight, and the track of the next system will allow warmer air to win out again, so while we’re looking at some areas starting as frozen precipitation, it ends up as largely a rain event, but with cold air not that far away to the north and west, we may see the precipitation end as a brief period of snow or snow showers on Monday. Behind that system comes more wind, and the arrival of colder air, reinforced even more with the passage of a secondary cold front on Tuesday. This sets up a snowier potential start to the next storm system, due in here later Wednesday, but while not a certain forecast, that one probably won’t end up staying as all snow either. More on that system next update.

TODAY: Clouds give way to sun. Highs 32-39. Wind NW up to 10 MPH.

TONIGHT: Clear. Lows 11-18. Wind calm.

SUNDAY: Increasing clouds. Highs 35-42. Wind variable up to 10 MPH.

SUNDAY NIGHT: Overcast. Rain, may start as snow/sleet southern NH and interior MA especially north of I-90. Lows 28-35 early, then rising slowly. Wind E-SE 5-15 MPH, higher gusts, becoming variable to N overnight.

MONDAY: Overcast with rain morning, possibly ending as snow or snow showers from west to east by midday. Clouds break for partial sun afternoon. Highs 37-44. Wind N to NW 10-20 MPH with higher gusts, especially later in the day.

MONDAY NIGHT: Partly cloudy. Lows 22-29. Wind W 10-20 MPH, gusty.

TUESDAY: Partly sunny. Highs 33-40. Wind NW 10-20 MPH, gusty.

TUESDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

WEDNESDAY: Clouding over. Snow/mix/rain at night. Highs 33-40. Wind NE 5-15 MPH.

DAYS 6-10 (JANUARY 26-30)

A lot of inconsistency and non-agreement in various medium range guidance (what else is new?). Overall less stormy in general, but still have to keep an eye on things for at least 1, possibly 2 disturbances. Temperatures a little closer to seasonal levels, but still no major cold expected.

DAYS 11-15 (JANUARY 31 – FEBRUARY 4)

Pattern trends colder. Watching a system for around February 2-3 with winter storm potential.

Friday January 20 2023 Forecast (7:21AM)

DAYS 1-5 (JANUARY 20-24)

Part 1 of the storm system is done, having produced mostly rain and some sleet initially, then a turn to snow in areas to the north, as expected, with up to an inch or 2 of accumulation from the initial burst of snow in those areas. Today, the upper low portion of the system comes across with numerous to widespread snow showers and another couple inches accumulation in northern areas and up to around an inch in some areas to the south, and less than 1 inch for most areas south of I-90 to nothing along the South Coast where it will take longest for what starts as rain showers to transition to mix/snow showers, and by then the moisture will have generally exited the region. This will happen this evening as drier air arrives and sets up an “ok” Saturday, not totally sunny, but precipitation-free and not too cold. But the active pattern rolls on and the next storm arrives later Sunday into Monday. Guidance has trended slightly colder with this over the last few runs, and we’ll continue to watch this, but for now expecting a rain event for the coast, rain/mix/snow potential inland, but just where and how much frozen precipitation is still unclear at this point. This will be addressed on the weekend blog forecast posts. After that second storm system, another small area of high pressure brings a break with fair weather for Tuesday. Also of note, the next few days high tides will cause at least minor flooding in prone areas at is one of the higher tides of 2023, astronomically.

TODAY: Cloudy. Scattered snow showers except rain showers to the south morning. Numerous to widespread snow showers except rain showers changing to snow showers to the south. Additional snow accumulation expected (see discussion for amounts). Highs 30-37 north, 37-44 south, occurring this morning and midday, with a slow fall to follow. Wind N up to 10 MPH.

TONIGHT: Variably cloudy. Chance of snow showers. Lows 23-30. Wind NW 10-20 MPH.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind NW 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

SUNDAY: Increasing clouds. Rain and some inland northern area mix/snow possible by late-day. Highs 37-44. Wind variable up to 10 MPH becoming NE to E and increasing to 10-20 MPH by late-day and evening.

SUNDAY NIGHT: Overcast. Rain likely except rain/mix/snow possible southern NH and portions of interior MA. Lows 32-39. Wind E 10-20 MPH, possibly stronger in coastal areas.

MONDAY: Overcast with rain to start, except mix/snow possible some inland locations, tapering off to rain and snow showers then ending. Breaking clouds follow. Highs 37-44. Wind SE or variable 10-20 MPH with higher gusts, shifting to W with stronger gusts especially by late in the day.

MONDAY NIGHT: Partly cloudy. Lows 22-29. Wind W 10-20 MPH, gusty.

TUESDAY: Partly sunny. Highs 33-40. Wind variable 5-15 MPH.

DAYS 6-10 (JANUARY 25-29)

Next storm potential January 25 can produce a variety of precipitation, but unknown until the storm’s track is more clearly known. Quieter period of weather begins after that one but probably a bit colder than we’ve been. Projection of a weaker disturbance passing by somewhere near the end of the period.

DAYS 11-15 (JANUARY 30 – FEBRUARY 3)

Quiet weather for the early portion of the period, and more seasonably chilly as well. Watching a storm threat way out there in time for around Groundhog Day.

Thursday January 19 2023 Forecast (7:32AM)

DAYS 1-5 (JANUARY 19-23)

An active weather pattern continues and we’ll be dealing with two storms during the next 5 days. The first one heads into our region today and lingers through Friday. It takes place as low pressure heading into the eastern Great Lakes redevelops off the northern Mid Atlantic Coast, just south of New England, and heads eastward. With a little more cold air around than in some of our recent events, we have a rain/snow line to deal with. Precipitation arrives toward dusk for areas to the west and near or just after dusk further east, mainly as rain but some mix/snow near and north of the MA/NH border, where it will remain steady state for the first few hours, before the rain/snow line begins a trek to the south during the late evening and overnight hours. The first batch of precipitation will taper off during the overnight, but not before a burst of moderate to heavy snow brings some accumulation to southern NH and a good portion of northern MA. After the surface storm departs, we still have the upper level low to go through the region on Friday from west to east, as the colder air continues to push southward, so this time the rain/snow line will continue further south and across the MA South Shore and the South Coast regions. The precipitation with the Friday portion of the system will not be as heavy, but it will be enough to add to the snow already on the ground to the north, and introduce some accumulation heading further south as well. When this system is done by later Friday evening, ending as snow showers, I expect that a solid 3-6 inches will have fallen across southern NH and northern MA, mainly north of the Route 2 / I-95 belt, with even a few 6+ amounts in higher elevations of north central MA and southwestern NH. We get a break Saturday between systems, a fair weather day with a narrow area of high pressure, and then the next system approaches during Sunday. There are still some questions with this one, but current indications are that the track of low pressure will cut more across our region, allowing enough warming so that more rain than snow will be involved, although we’d have to watch for snow at the start and possibly the end, especially for northern and western portions of the area. Of course, fine-tuning will be done for this event during the next few days with a solid final call by Sunday’s blog post. This system lingers into Monday before we see improvement arriving, but the departure of that system may come with quite a bit of wind as well.

TODAY: Sun followed by clouds. Rain arriving west to east afternoon, except possible sleet and snow interior northern MA and southern NH. Highs 38-45 but may turn cooler late-day. Wind variable to NE up to 10 MPH.

TONIGHT: Overcast. Sleet/snow southern NH and northern MA, rain to the south, slowly transitioning to mix/snow into the Route 2 / I-95 region of northern and northeastern MA while remaining mostly rain to the south, tapering off overnight. Lows 30-37. Wind NE 10-20 MPH.

FRIDAY: Cloudy. Periodic snow, except rain/mix turning to snow southern areas. Temperatures steady 30-37. Wind N 10-20 MPH.

FRIDAY NIGHT: Variably cloudy. Chance of snow showers. Lows 23-30. Wind NW 10-20 MPH.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind NW 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

SUNDAY: Increasing clouds. Rain and some inland northern area mix/snow possible by late-day. Highs 37-44. Wind variable up to 10 MPH becoming NE to E and increasing to 10-20 MPH by late-day and evening.

SUNDAY NIGHT: Overcast. Rain likely except rain/mix/snow possible southern NH and interior northern MA. Lows 32-39. Wind E to SE 10-20 MPH, possibly stronger in coastal areas.

MONDAY: Overcast with rain to start, tapering off to showers then ending. Breaking clouds follow. Highs 40-47. Wind SE to SW 15-25 MPH, shifting to W with higher gusts especially later in the day.

DAYS 6-10 (JANUARY 24-28)

Next storm potential around January 25 can produce a variety of precipitation, but may end up being a colder storm than the previous one. Quieter period of weather begins after that one but probably a bit colder than we’ve been.

DAYS 11-15 (JANUARY 29 – FEBRUARY 2)

Quiet weather for the early to middle portion of the period, and more seasonably chilly as well. Watching a storm threat for later in the period.

Wednesday January 18 2023 Forecast (7:40AM)

DAYS 1-5 (JANUARY 18-22)

An upper level trough and surface cold front swings through the region this morning and midday with lots of clouds and the threat of a rain shower, followed by fair weather the rest of the day, and still mild despite a gusty breeze. A small area of high pressure brings more traquil and dry weather overnight into early Thursday, but clouds advance quickly on Thursday ahead of the next low pressure system. The initial primary low center is destined for the eastern Great Lakes but will redevelop near or just south of the New England South Coast Thursday night and early Friday as it tracks to the east. This will be followed by the trough which remains of the old low during Friday, drawing out this unsettled period, which will also have frozen precipitation involved. A rain/snow line should be present at the start of the event with snow in interior northern MA and southern NH, rain elsewhere. This rain/snow line will waver around, probably heading north for a time before coming back to the south, then progressing even further south on Friday as we transition from steadiest precipitation into more occasional. The change-over will probably not quite make it all the way through the South Coast region before the end of the precipitation. This sets up a snow (and some sleet) accumulation profile that by the time we wind things up on Friday evening will look like this: traces / coatings of snow south of I-90, but maybe up to 1 inch in the higher elevations of south central MA, northwestern RI, and northeastern CT, a general 1-3 inch snowfall north of I-90 except 3-5 inches north central MA and southern NH. The weekend starts off fair with high pressure moving in during Saturday, then ends with a return to unsettled weather as low pressure approaches on Sunday, spreading a shield of rain in that may start as mix/snow for some inland areas by late in the day or evening, based on current expecting timing.

TODAY: Mostly cloudy to partly sunny. A passing rain shower possible through midday. Highs 45-52. Wind W 5-15 MPH this morning, NW 10-20 MPH with possible higher gusts this afternoon.

TONIGHT: Partly cloudy to mostly clear. Lows 24-31. Wind W under 10 MPH.

THURSDAY: Sun followed by clouds. Rain arriving west to east afternoon, except possible sleet and snow interior northern MA and southern NH. Highs 38-45 but may turn cooler late-day. Wind variable to NE up to 10 MPH.

THURSDAY NIGHT: Cloudy with rain/mix/snow likely with greatest chance of frozen/mix I-495 west south of I-90, and I-90 north otherwise. Lows 31-38. Wind NE 10-20 MPH.

FRIDAY: Mostly cloudy. Periods of rain/mix South Coast, periods of snow elsewhere, tapering with time. Highs 33-40. Wind N 10-20 MPH.

FRIDAY NIGHT: Variably cloudy. Chance of snow showers. Lows 23-30. Wind NW 10-20 MPH.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind NW 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 17-24. Wind N up to 10 MPH.

SUNDAY: Increasing clouds. Rain and some inland northern area mix/snow possible by late-day. Highs 37-44. Wind variable up to 10 MPH becoming NE to E and increasing to 10-20 MPH by late-day and evening.

DAYS 6-10 (JANUARY 23-27)

Stormy start January 23 with low pressure cutting across the region, based on current expectations. Should have warmed up enough for mostly rain but will keep an eye on it. Dry interlude briefly between that system and the next one expected in the January 25-26 window – will fine-tune that. Drier/chilly weather to end the period behind that system.

DAYS 11-15 (JANUARY 28 – FEBRUARY 1)

A quieter, more seasonably chilly period of weather is anticipated here with maybe one minor disturbance bringing a snow shower risk.

Tuesday January 17 2023 Forecast (7:44AM)

DAYS 1-5 (JANUARY 17-21)

We will see a rare appearance of full sunshine for several hours today as we’re in an area of dry air behind the now-departed ocean storm, but clouds will be moving in quickly this afternoon ahead of the next low, approaching from the Midwest / northern Mid Atlantic. This system will be weakening and its precipitation shield may survive as a small area of light rain this evening before dissipating. The system will be in the process of being absorbed by the ocean storm Wednesday as we find ourselves in a northwesterly air flow behind it, with dry weather and a gusty breeze, but on the mild side since there is not really any cold air to be tapped just yet. A weak area of high pressure moves across the region Wednesday night into early Thursday with tranquil weather, but in this active pattern the next low, this one more formidable, makes its way into the Northeast during Thursday and Thursday night with extensive cloud cover and a shield of precipitation. The set-up for that system is a bit more complex, as at that time we’ll have colder air starting to press in from the north. While I think most start as rain (maybe some mix in southern NH), we likely see a transition to a larger area of sleet and snow where north of and up to the I-90 belt, but not exactly sure on timing and location for a rain/sleet/snow zones. That will be monitored and fine-tuned over the next couple days. This will be an elongated system with a trough behind the initial low passing through on Friday with additional precipitation, probably mostly snow showers, except rain/mix/snow to the south closer to the South Coast. Drier weather should be back with us for the start of the weekend.

TODAY: Sun followed by clouds. Highs 39-46. Wind variable to W 5-10 MPH.

TONIGHT: Mostly cloudy. A period of light rain possible during the evening. Lows 32-39. Wind S up to 10 MPH.

WEDNESDAY: Mostly cloudy to partly sunny. Highs 45-52. Wind NW 5-15 MPH, a few higher gusts.

WEDNESDAY NIGHT: Partly cloudy to mostly clear. Lows 24-31. Wind W under 10 MPH.

THURSDAY: Sun followed by clouds. Rain arriving west to east afternoon, except possible rain/sleet/snow mix southern NH. Highs 38-45 but may turn cooler late-day. Wind variable to NE up to 10 MPH.

THURSDAY NIGHT: Cloudy with rain/mix/snow likely with greatest chance of frozen/mix in northern areas. Lows 31-38. Wind NE 10-20 MPH.

FRIDAY: Mostly cloudy with mix/snow showers likely. Highs 35-42. Wind N 10-20 MPH.

FRIDAY NIGHT: Variably cloudy. Chance of snow showers. Lows 23-30. Wind NW 10-20 MPH.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind NW 5-15 MPH.

DAYS 6-10 (JANUARY 22-26)

Low pressure impact potentials January 22 into January 23, and again late in the period as we remain in an active pattern. Too soon to determine disturbance intensity and precipitation type. Temperatures mostly above normal, though variable.

DAYS 11-15 (JANUARY 27-31)

General pattern looks like it leaves the door open for more seasonable cold, at least in 1 or 2 shots with passing disturbances originating further north than previously, but some guidance suggest one potential more substantial precipitation producer coming from Gulf of Mexico moisture, so that will be something to keep an eye on in the days ahead.

Monday January 16 2023 Forecast (6:45AM)

DAYS 1-5 (JANUARY 16-20)

A lobe of snow and some sleet will move quickly north to south this morning across the region on the back side of a complex ocean storm to our south and east. Some lingering rain and snow showers may be near coastal areas into this afternoon as well. The entire conglomeration moves more seaward away from New England later today onward, losing its grip on this region, but making way for another low pressure area approaching via the Midwest by later on Tuesday. This system, feeling the effects of the larger offshore circulation, will begin to yield to it and weaken, but its weakening precipitation shield will cross our region Tuesday evening, but not before we sneak in a few hours of nice weather to start the day on Tuesday. Behind this system a small area of high pressure builds in with fair weather Wednesday, but it will be on the mild side – definitely the pick of the week for combined dry and mild weather. Thursday also starts out nice, but clouds move in ahead of the next low pressure system heading our way from the Midwest and Ohio Valley. This is another system that originated in the active Pacific jet stream pattern. For us it will come along with mild enough air so that despite some mix/snow potential at the start, it will likely end up as mostly a rain event. But as the surface storm starts to move out on Friday we’ll still have to deal with upper level low pressure and somewhat cooler to colder air, so precipitation will probably go over to mix/snow showers as we remain unsettled that day, continuing the overall pattern we’ve seen so far this first month of 2023 which lacks sun and doesn’t lack low pressure moving through the region.

TODAY: Cloudy start with a period of snow and sleet moving north to south across the region, may be heavy for a brief time, then lots of clouds with occasional snow and rain showers favoring eastern areas, tapering off later in the day. Highs 35-42. Wind N to NW 10-20 MPH, higher gusts especially coastal areas.

TONIGHT: Clearing. Lows 25-32. Wind NW to W diminishing to under 10 MPH.

TUESDAY: Early sun, then clouds return. Highs 38-45. Wind variable up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Spotty light rain/mix possible. Lows 33-40. Wind S up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 45-52. Wind W up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 23-30. Wind variable under 10 MPH.

THURSDAY: Sun followed by clouds. Late-day snow/mix/rain possible. Highs 40-47. Wind variable to E up to 10 MPH.

THURSDAY NIGHT: Cloudy with rain/mix/snow likely. Lows 32-39. Wind E 10-20 MPH.

FRIDAY: Mostly cloudy with mix/snow showers lingering. Highs 35-42. Wind N 10-20 MPH.

DAYS 6-10 (JANUARY 21-25)

Storm signal around January 23 (late 1-22 to early 1-24) – the last in the long-running Pacific parade. Too soon for details. Dry weather either side. Temperatures near to above normal.

DAYS 11-15 (JANUARY 26-30)

Overall drier, cooler trend but no signal for major cold at this point. Still will see a couple disturbances coming by but the origin is a little different than previously – systems translating across the country that have come into North America a little further north and with less moisture than we saw in the previous pattern. A couple of those bring precipitation opportunities for this region sometime during the final week of the month. Overall cooling trend in temperature but still no signal for major cold in this region.

Sunday January 15 2023 Forecast (6:58AM)

DAYS 1-5 (JANUARY 15-19)

Our region will be on the fringes of a large ocean storm today into Monday, but this storm’s main impact will be at sea, offshore. The fringe effects for southeastern New England will include some rain and snow for mainly southeastern MA and Cape Cod, along with gusty winds, especially in coastal areas, strongest also over southeastern MA and Cape Cod into Monday, before the low center starts to pull away to the east. While drier and colder air working southward into New England from eastern Canada will trend any precipitation to snow after the initial rain and mix, the dry air will also eat away at the western edge of the synoptic precipitation. Some ocean-effect mix to snow bands will likely occur from the South Shore surviving to the South Coast and across Cape Cod during this time. As far as model depiction goes, caution for model watchers that the global guidance at this range tends to over emphasize the precipitation area and how far west it gets, and the higher resolution shorter range guidance is likely a better representation of how the system plays out. Measurable snowfall should be confined mostly to the South Shore down into Cape Cod (after the wetter start there), with mainly traces of mix to snow with some minor accumulation working back into the I-95 belt and a few flurries of snow out into the I-495 belt from drying synoptic snowfall. Some sunshine may even appear at times over inland locations from south central and southwestern NH through central MA into eastern CT and possibly even RI as drier air wraps around the back side of the offshore storm, and we should see an increase in the sunshine further east as the system pulls further away by later Monday. But any clearing will be rather short-lived, as the next low pressure system from the west will spread its clouds into the region during Tuesday. As previously indicated, this system will be feeling the effect of the dry air behind the ocean storm, and will begin to fall apart, with maybe a little bit of rain and mix surviving into our region Tuesday evening as milder air also arrives. A small area of high pressure is expected to bring fair weather and somewhat above normal temperatures to our region at midweek. Currently, I am leaning toward a slower arrival of the next system behind that, which has been modeled to impact our region on Thursday, but I feel may not arrive until after we reach the end of this 5-day forecast period. Will monitor that and readjust the timing if necessary.

TODAY: Mainly cloudy – heaviest clouds eastern areas, partial sun possible well inland. Periods of rain and mix transitioning to mix and snow MA South Shore through Cape Cod working into the South Coast region of MA. Highs 35-42. Wind NE 10-20 MPH, higher gusts especially coastal areas.

TONIGHT: Mainly cloudy. Mix/snow most likely Cape Cod, South Coast and South Shore of MA where a general coating to 2 inches of snow is likely, with isolated amounts up to 3 inches possible in some South Shore areas. Snow showers from I-95 to I-495 belts with under 1 inch of accumulation. Lows 26-33. Wind N 10-20 MPH, gusts 25-45 MPH, strongest coastal areas.

MONDAY: Mostly cloudy eastern coastal areas with snow showers early, otherwise increasing sun from west to east gradually. Highs 34-41. Wind N to NW 10-20 MPH, higher gusts, especially in coastal areas.

MONDAY NIGHT: Partly cloudy. Lows 25-32. Wind NW to W diminishing to under 10 MPH.

TUESDAY: Early sun, then clouds return. Highs 38-45. Wind variable up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Spotty light rain/mix possible. Lows 33-40. Wind S up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 46-53. Wind W up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 23-30. Wind variable under 10 MPH.

THURSDAY: Sun and high clouds. Highs 42-49. Wind variable to SE up to 10 MPH.

DAYS 6-10 (JANUARY 20-24)

Low pressure systems should impact the region with precipitation threats January 20, 22, and 24, based on current timing, the final systems in a Pacific parade as the pattern starts to change, shutting off the Pacific flow. Temperatures above normal, although variable.

DAYS 11-15 (JANUARY 25-29)

The pattern heading into the late days of the month looks a little less active with more high pressure in control across the Great Lakes and Northeast, and one or two frontal boundaries bringing brief, minor precipitation threats. Temperatures near to above normal with a couple colder shots, but nothing extreme.

Saturday January 14 2023 Forecast (9:10AM)

DAYS 1-5 (JANUARY 14-18)

A mainly dry MLK Weekend, though lacking in sunshine, for most areas. One exception is this morning, as a disturbance passes through, some light precipitation in the form of rain, sleet, and in some areas snow grains (which just dusted cold surfaces here in Woburn before I wrote this). Low pressure moving off the Mid Atlantic meanders well south to well east of New England, but with a large circulation we will be in its envelope of northeast to north wind during Sunday and Monday, and some of its precipitation will wheel into the Cape Cod and southeastern MA region mainly from early Sunday to early Monday. With a mild ocean temperature and marginal air temperatures anyway there will be a fine line between liquid and frozen precipitation where it occurs, with a gradual trend from liquid to frozen overall. With a touch of ocean-enhancement, a slow-occurring snow accumulation of up to 3 inches may occur in southeastern MA during this time before the low starts to pull away. While it does that, it sheds some of its synoptic precipitation westward, but this is usually overdone by models and I am not expecting much of an impact other than some sprinkles / flurries over other portions of eastern MA up to around the NH Seacoast, especially Sunday afternoon and night. But for most locations, this will be a mainly dry 3-day stretch of weather. The next system moves in from the west by Tuesday, but will be undergoing a weakening trend due to the larger system well offshore, so we’ll have lots of clouds coming back after a brighter start to the day, but if any precipitation survives it would likely fall as a light mix of rain/snow or just light rain sometime that evening before vanishing. This leaves us with a fair and milder Wednesday as high pressure moves into the region, but not from a cold weather source region.

TODAY: Cloudy morning with areas of drizzle, very light rain, sleet, and snow grains. Mostly cloudy afternoon. Highs 37-43. Wind NW-N increasing to 10-20 MPH.

TONIGHT: Variably cloudy. Lows 25-32. Wind N 10-20 MPH, higher gusts.

SUNDAY: Mostly cloudy. Episodes of rain and snow Cape Cod and southeastern MA where some minor snow accumulation is possible inland southeastern MA. Highs 35-42. Wind N-NE 10-20 MPH, higher gusts especially coastal areas.

SUNDAY NIGHT: Mostly cloudy. Additional snow/mix showers southeastern MA and Cape Cod with additional minor snow accumulation. Lows 27-34. Wind N 10-20 MPH, higher gusts near the coast.

MONDAY: Partly sunny. Additional morning rain/snow possible southeastern MA. Highs 35-42. Wind N 5-15 MPH, higher gusts especially near the coast.

MONDAY NIGHT: Variably cloudy. Lows 25-32. Wind NW up to 10 MPH becoming variable.

TUESDAY: Early sun, then clouds return. Highs 38-45. Wind variable up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Spotty light rain/mix possible. Lows 33-40. Wind S up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 46-53. Wind W up to 10 MPH.

DAYS 6-10 (JANUARY 19-23)

We’ll start to see a transition out of the Pacific flow pattern, but not a quick change, so we still have 2 shots at precipitation from the last couple systems, around January 19 and 22, based on current timing. Temperatures above normal overall, but somewhat variable.

DAYS 11-15 (JANUARY 24-28)

Less Pacific flow and a little more Canadian flow is expected, with a more seasonable temperature pattern evolving, but still lacking strong cold shots. We’ll have to watch for one or two potential precipitation threats but they may be rather minor for a lack of moisture available.

Friday January 13 2023 Forecast (7:35AM)

DAYS 1-5 (JANUARY 13-17)

Low pressure tracks into eastern Canada today and its cold front moves across the region. It will be a mild day with rain showers around, but the heaviest band of rain occurs early in southeastern areas. Drier air works in later today and tonight. Complete clearing will be hard to come by though as the front is not that far offshore Saturday, and while it’s precipitation-free, we can expect a lot of clouds to hang around to start the long weekend. As we move through the weekend, we’ll watch the development and evolution of a new storm to the south and southeast of New England, in a slow-moving upper air pattern. The storm will be close enough to impact the region with a northeast to north wind, and may toss some rain and snow showers back into coastal areas, especially during a portion of Sunday, but the precipitation from this will largely remain offshore. Bands of precipitation that radiate outward from the low will run into dry air and dissipate in the process of doing so, but this may add to the cloudiness as there are a lot of mid and high level clouds associated with this system that can expand over the region. We will have to watch for a band or two of ocean effect mix/snow showers as well especially for the South Shore and Cape Cod. This system should be heading back out by Monday with fair weather, but the previously talked about tranquility may be a bit delayed since we may still be under the influence of the low’s wind circulation and the high from the west will be in the process of getting squeezed between that storm and an approaching low pressure area from the Midwest. The latter of the two will start to impact our region on Tuesday, but it will also be feeling the influence of the much larger ocean storm and will likely begin a process of weakening, eventually to be absorbed by that circulation offshore. So its impact on us may be more in the form of cloudiness than precipitation.

TODAY: Cloudy morning with widespread rain showers southeastern MA into mid morning, otherwise scattered rain showers through the morning. Mostly cloudy this afternoon with an additional rain shower possible. Highs ranging from 45-52 in far north central MA and southwestern NH to 53-60 elsewhere. Wind S 10-20 MPH except 15-30 MPH southeastern MA, higher gusts in all areas, shifting to W during the day, with the exception of an area of lighter and variable wind this morning where it is cooler well northwest of Boston.

TONIGHT: Mostly cloudy. Lows 30-37. Wind W to NW 10-20 MPH, gusty.

SATURDAY: Lots of clouds, breaks of sun. Highs 37-43. Wind NW-N 10-20 MPH, gusty.

SATURDAY NIGHT: Variably cloudy. Lows 25-32. Wind N 10-20 MPH, higher gusts.

SUNDAY: Variably cloudy. Rain/snow showers possible in coastal locations. Highs 35-42. Wind N-NE 10-20 MPH, higher gusts especially coastal areas.

SUNDAY NIGHT: Mostly cloudy. Additional snow/mix showers possible near the coast. Lows 25-32. Wind N under 10 MPH.

MONDAY: Partly sunny. Highs 35-42. Wind N 5-15 MPH, higher gusts especially near the coast.

MONDAY NIGHT: Variably cloudy. Lows 25-32. Wind NW up to 10 MPH becoming variable.

TUESDAY: Mostly cloudy. Light rain/mix/snow possible. Highs 38-45. Wind variable up to 10 MPH.

DAYS 6-10 (JANUARY 18-22)

Next low pressure threat around mid period, trends a little weaker on guidance at this time possibly in response to lingering offshore low pressure and lack of support, but will watch it for a snow/mix/rain threat. Dry before it and after it. Temperatures near to above normal – no major cold.

DAYS 11-15 (JANUARY 23-27)

Less Pacific flow and a little more Canadian flow is expected, with a more seasonable temperature pattern, but still lacking strong cold shots. We’ll have to watch for one or two potential precipitation threats but they may be rather minor for a lack of moisture available, depending on the set-up.

Thursday January 12 2023 Forecast (7:28AM)

DAYS 1-5 (JANUARY 12-16)

A little surprise ocean-effect snow from Boston into the northwestern suburbs and the North Shore with low level moisture moving in from the southeast overnight with air cold enough to support flakes. We’ve had a minor accumulation / coating, just enough to slick up some roads and walks that were not treated, so be cautious if you have to travel early today before the temperature goes above freezing and it all vanishes. During the day today, with the approach of a warm front, we will still be under an overcast with scattered light precipitation, back to rain for the coastal plain and I-95 belt with a bit of freezing rain in pockets off to the northwest and snow well to the northwest, as mentioned on yesterday’s discussion. Still expecting the system passing to our northwest to give us most of its rain in the warm sector later tonight into Friday morning before the cold front pulls through and we start a dry-out process during the afternoon on Friday. A developing storm on the offshore front will tease far eastern New England with some clouds at times this weekend, and the rain/snow shield may make a run for outer Cape Cod briefly, but I expect it to stay offshore and keep the region dry between the storm and high pressure to the west, the latter of which will move in for MLK Jr Day on Monday with fair and more tranquil weather after a gusty breeze during Saturday and Sunday.

TODAY: Cloudy. Spotty light rain that may freeze on some surfaces well northwest of Boston and be in the form of snow for a while from southwestern NH into central MA before all transitioning to rain later. Highs 36-43. Wind E up to 10 MPH.

TONIGHT: Cloudy. Periods of rain including embedded heavier showers with the chance of thunder. Areas of fog developing. Temperatures rising through the 40s. Wind SE 5-15 MPH, gusts 20-25 MPH, strongest coast where gusts above 30 MPH are possible.

FRIDAY: Cloudy morning with numerous showers and a slight chance of thunder, especially southeastern NH through eastern MA and RI. Breaking clouds with partial sun possible midday on. Highs 48-55. Wind SW 10-20 MPH with higher gusts, shifting to W.

FRIDAY NIGHT: Partly cloudy. Lows 28-35. Wind NW 10-20 MPH, higher gusts in the evening, shifting to N.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind N 10-20 MPH, higher gusts especially coastal areas.

SATURDAY NIGHT: Partly cloudy. Lows 22-29. Wind N 10-20 MPH, higher gusts especially coastal areas.

SUNDAY: Mostly sunny. Highs 33-40. Wind N 10-20 MPH, higher gusts especially coastal areas, diminishing later in the day.

SUNDAY NIGHT: Clear. Lows 15-22. Wind N under 10 MPH.

MONDAY: Sunny. Highs 35-42. Wind variable up to 10 MPH.

DAYS 6-10 (JANUARY 17-21)

Low pressure may still linger offshore early in the period and make a loop back, essentially dismantling an approaching front from the west on January 17, so we may end with lots of clouds but not much, if any, precipitation from that system, followed by high pressure with dry weather for a couple days. Another storm system from the west may move in later in the period with a rain/mix/snow threat, but this is low confidence.

DAYS 11-15 (JANUARY 22-26)

A little less Pacific flow and a little more Canadian flow is expected, with a more seasonable temperature pattern. We’ll have to watch for one or two potential precipitation threats but they may be rather minor for a lack of moisture available, depending on the set-up.

Wednesday January 11 2023 Forecast (7:44AM)

DAYS 1-5 (JANUARY 11-15)

High pressure brings fair weather to the region today with an “easy chill”, a cool day, above the average, and not much wind. Things still look much the same for our upcoming unsettled weather passing through. We cloud up and have spotty light rain and snow around on Thursday (snow most likely away from the coast, but light!), although some of the rain that falls may freeze on surfaces with temperatures just cold enough, as warm air tries to move in both surface and aloft ahead of low pressure. This low ultimately takes a track to our northwest and when we get into the warm sector is when we see our heaviest rainfall, Thursday night / early Friday morning, which may even include some thunder, but timing is fast enough that the cold front from the low sweeps through and offshore, so that most of Friday is rain-free, just windy and cool with breaking clouds. Additional low pressure evolves on the offshore front as it slows down as we get into the weekend, far enough to our east so that we see fair weather, but close enough so we feel a chilly northerly breeze from it, in combination with high pressure to our west at that time.

TODAY: Sun/cloud mix. Highs 37-44. Wind N up to 10 MPH.

TONIGHT: Mostly cloudy. Lows 28-35. Wind NE up to 10 MPH.

THURSDAY: Cloudy. Spotty light rain, freezing rain, and snow especially afternoon. Highs 36-43. Wind E up to 10 MPH.

THURSDAY NIGHT: Cloudy. Periods of rain including embedded heavier showers with the chance of thunder. Areas of fog developing. Temperatures rising through the 40s. Wind SE 5-15 MPH, gusts 20-25 MPH, strongest coast where gusts above 30 MPH are possible.

FRIDAY: A cloudy start with showers ending, then lots of clouds but breaks of sun. Highs 48-55. Wind SW 10-20 MPH with higher gusts, shifting to W.

FRIDAY NIGHT: Partly cloudy. Lows 28-35. Wind NW 10-20 MPH, higher gusts in the evening, shifting to N.

SATURDAY: Sun/cloud mix. Highs 35-42. Wind N 10-20 MPH.

SATURDAY NIGHT: Partly cloudy. Lows 22-29. Wind N 10-20 MPH.

SUNDAY: Mostly sunny. Highs 33-40. Wind N 10-20 MPH.

DAYS 6-10 (JANUARY 16-20)

High pressure nudges east for a dry, more tranquil, chilly MLK Jr. Day. Frontal system from the west brings unsettled weather but maybe more clouds than precipitation for January 17 as it will be running into a non-supporting roadblock in the atmosphere. Chilly, dry weather follows this but as the flow in the atmosphere quickens it may be unsettled again by the end of the period with a rain/mix/snow threat.

DAYS 11-15 (JANUARY 21-25)

This looks like a drier period that trends somewhat cooler to colder as we lose the Pacific flow and gradually re-introduce Canadian air to our region. Not sure yet if one more Pacific system will try to move through during transition, otherwise watch for a weaker low out of Canada with a minor precipitation threat around mid period.

Tuesday January 10 2023 Forecast (7:58AM)

DAYS 1-5 (JANUARY 10-14)

A very quick update this morning… No big changes to yesterday’s ideas. Weak trough swinging through early today with clouds, then dry air returns into midweek with high pressure to the north. Watching low pressure for later this week. Models remain inconsistent and divergent and the overall idea remains the same. Unsettled weather (more clouds than precipitation) with a warm front Thursday, and low pressure tracking northwest of us Friday with a “glorified frontal passage” with rain, some heavy, and gusty winds (probably not damaging though). Improvement, while potentially slow at first, should be here in time for the start of the weekend.

TODAY: Lots of clouds, then mostly sunny. Highs 37-44. Wind NW 5-15 MPH.

TONIGHT: Mostly clear. Lows 18-25. Wind N up to 10 MPH.

WEDNESDAY: Sun/cloud mix. Highs 37-44. Wind N up to 10 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Lows 28-35. Wind NE up to 10 MPH.

THURSDAY: Mostly cloudy. Highs 37-44. Wind E up to 10 MPH.

THURSDAY NIGHT: Cloudy. Periods of rain. Areas of fog developing. Temperatures steady 37-44 evening then rising slowly overnight. Wind SE 5-15 MPH.

FRIDAY: Cloudy. Periods of rain. Highs 43-50, mildest South Coast. Wind S 10-20 MPH, higher gusts especially South Coast.

FRIDAY NIGHT: Clouds break. Showers end. Lows 33-40. Wind SW 10-20 MPH.

SATURDAY: Variably cloudy. Rain showers possible early favoring eastern areas. Highs 40-47. Wind NW 10-20 MPH with higher gusts.

DAYS 6-10 (JANUARY 15-19)

High pressure brings dry weather for the balance of MLK Jr. Weekend. Frontal system from the west brings unsettled weather mid period. Fair, chilly, dry weather late period.

DAYS 11-15 (JANUARY 20-24)

This looks like a drier period that trends somewhat cooler to colder as we lose the Pacific flow and gradually re-introduce Canadian air to our region. Somewhere around mid period watch for a fast moving system with a little bit of precipitation.

Monday January 9 2023 Forecast (7:01AM)

QUICK NOTE

With a major project ongoing at home this week, there is a possibility that a couple days the blog may be late, or very brief, and if I’m lucky, that won’t be the case. My ability to check in will also be limited, but I’ll do it when I can.

DAYS 1-5 (JANUARY 9-13)

The weather during this work week (Monday-Friday) will be fairly quiet until we get to the end of it. First, a quick shot of rain and some wet snow for southeastern areas with low pressure passing to our south early today before the system moves out and clouds give way to sun. A weak trough swings through early Tuesday, but you won’t really notice it, because it’s not really going to do anything, and then high pressure in eastern Canada keeps us dry with a bit of a chill in the air into midweek. As low pressure gets organized in the Midwest Thursday, its warm front will spread a deck of clouds into our region, but right now other than a little spotty light rain or snow, mostly to our north, I’m not really expecting much to happen with this front. The low center will pass to our northwest on Friday, which will be an unsettled day with a gusty breeze and periods of rain likely, but also above normal temperatures, as the mild side of our ongoing La Nina pattern continues.

TODAY: Cloudy morning with a touch of rain possible Outer Cape Cod and Islands, then increasing sun. Highs 38-45. Wind variable up to 10 MPH.

TONIGHT: Mostly clear to partly cloudy. Lows 26-33. Wind W 5-15 MPH.

TUESDAY: Partly cloudy to mostly sunny. Highs 37-44. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 18-25. Wind N up to 10 MPH.

WEDNESDAY: Sun/cloud mix. Highs 37-44. Wind N up to 10 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Lows 28-35. Wind NE up to 10 MPH.

THURSDAY: Mostly cloudy. Highs 37-44. Wind E up to 10 MPH.

THURSDAY NIGHT: Cloudy. Periods of rain. Areas of fog developing. Temperatures steady 37-44 evening then rising slowly overnight. Wind SE 5-15 MPH.

FRIDAY: Cloudy. Periods of rain. Highs 43-50, mildest South Coast. Wind S 10-20 MPH, higher gusts especially South Coast.

DAYS 6-10 (JANUARY 14-18)

The MLK Jr. weekend looks generally dry but evolving from breezy and chilly Saturday with a sun/cloud mix to a sunnier and chilly but more tranquil Sunday, to a variably cloudy holiday with a slight temperature moderation but a possible onshore breeze, depending on orientation of high pressure. Watching the end of the period for a frontal system from the west passing by with milder air, rain showers, then cooler/drier air behind it – but confidence is low on details and timing since it’s pretty far into the future.

DAYS 11-15 (JANUARY 19-23)

This looks like a drier period that trends somewhat cooler to colder as we lose the Pacific flow and gradually re-introduce Canadian air to our region. Somewhere around mid period watch for a fast moving system with a little bit of precipitation.

Sunday January 8 2023 Forecast (7:43AM)

DAYS 1-5 (JANUARY 8-12)

High pressure brings fair but chilly weather to our region during today. Low pressure passes south of the region late tonight into Monday, close enough to drag its shield of cloudiness across our sky but far enough to keep its precipitation to our south. A trough swings through the region early Tuesday delivering some reinforcement of seasonably chilly air into the region. As we head through midweek, we’ll have to keep an eye on high pressure in eastern Canada and a boundary to our south, which eventually becomes an avenue for low pressure. I’m not trusting guidance handling of the set-up very much but what I think may take place is an initial disturbance tries to make a run at our region but doesn’t quite manage to survive at midweek, with a more formidable system approaching by later Thursday. Bottom line is my leaning is toward more clouds for midweek than actual storminess, with the latter likely holding off.

TODAY: Sun and high clouds. Highs 35-42. Wind NW to W up to 10 MPH.

TONIGHT: High to middle clouds overspread the sky. Lows 22-29. Wind W to SW under 10 MPH.

MONDAY: Considerably cloudy beginning trending to a mostly sunny finish. Highs 38-45. Wind SW to variable up to 10 MPH.

MONDAY NIGHT: Mostly clear. Lows 23-30. Wind variable to W up to 10 MPH.

TUESDAY: Partly sunny. A brief passing snow shower possible through midday. Highs 36-43. Wind NW 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 13-20. Wind N 5-15 MPH, diminishing.

WEDNESDAY: Sun gives way to clouds. Highs 35-42. Wind N 5-15 MPH.

WEDNESDAY NIGHT: Partly to mostly cloudy. Lows 28-35. Wind variable up to 10 MPH.

THURSDAY: Mostly cloudy. Highs 38-45. Wind variable up to 10 MPH.

DAYS 6-10 (JANUARY 13-17)

Low pressure passing through the Northeast early in the period with with a track that favors rain over snow, and another frontal boundary may approach by the end of the period, with a dry holiday weekend between. Temperatures near to above normal overall, but a brief shot of cold air behind the initial storm system.

DAYS 11-15 (JANUARY 18-22)

Low confidence outlook for above normal temperatures and a somewhat active storm tracking bringing 1 or 2 unsettled weather opportunities. Odds would favor low pressure tracks through the Midwest / Great Lakes and rain over snow for this area, but much can change between now and then so only take this is a general idea for now.
