Here ’tis.

DAYS 1-5 (DECEMBER 25-29)

Merry Christmas! We will have a quiet but cold holiday overall. A snow band that has dropped several inches of snow over Martha’s Vineyard and up to a few inches along parts of the South Coast will fade away during the day. Otherwise, high pressure will bring fair, cold weather today into the early portion of the week with a moderation in temperature following that.

TODAY (CHRISTMAS): Snow showers with additional light accumulation Islands to South Coast, diminishing by midday, otherwise partly cloudy to mostly sunny. Highs 23-30. Wind W 5-15 MPH.

TONIGHT: Clear. Lows 12-19. Wind W 5-15 MPH.

MONDAY: Sunny. Highs 26-33. Wind W up to 10 MPH.

MONDAY NIGHT: Mostly clear. Lows 13-20. Wind WSW up to 10 MPH.

TUESDAY: Partly cloudy. Highs 28-35. Wind SW 5-15 MPH shifting to NW.

TUESDAY NIGHT: Partly cloudy. Lows 15-22. Wind NW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 32-39. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 18-25. Wind variable up to 10 MPH.

THURSDAY: Mostly sunny. Highs 38-45. Wind SW up to 10 MPH.

DAYS 6-10 (DECEMBER 30 – JANUARY 3)

Fair and mild weather is expected with high pressure off the Atlantic Coast for the final couple days of 2022. Unsettled weather, likely rain or rain showers, with low pressure and a frontal system moving through the region to greet 2023, followed by dry and somewhat cooler weather.

DAYS 11-15 (JANUARY 4-8)

One or two relatively minor systems with precipitation threats during this period with a generally west to east flow. Variable temperatures averaging near to above normal.

DAYS 1-5 (DECEMBER 24-28)

Christmas Weekend will be a cold one, and mainly dry, behind the big storm. Today will be the windier of the the two days, and some ocean-effect snow is expected along the South Coast, especially Cape Cod and the Islands. Otherwise, generally dry weather is expected with only the remote chance of a few snow flurries making their way into the region via the Great Lakes. Cold weather eases up slightly but generally continues into early next week. Watching for a disturbance with a snow shower threat about Tuesday.

TODAY: Sun/cloud mix. Isolated to scattered snow showers possible, especially South Coast. Snow accumulation of up to 3 inches islands, especially Martha’s Vineyard, and up to 1 inch South Coast especially Cape Cod. Highs 20-27. Wind SW 15-25 MPH, higher gusts. Wind chill around 10.

TONIGHT (CHRISTMAS EVE): Partly cloudy. Isolated snow showers, but additional scattered snow showers in the South Coast region. Lows 12-19. Wind WSW 10-20 MPH. Wind chill below 10.

SUNDAY (CHRISTMAS): Mostly sunny. Slight chance of an isolated light snow shower. Highs 23-30. Wind W 5-15 MPH, higher gusts. Wind chill below 20.

SUNDAY NIGHT: Clear. Lows 12-19. Wind W 5-15 MPH.

MONDAY: Sunny. Highs 26-33. Wind W up to 10 MPH.

MONDAY NIGHT: Mostly clear. Lows 13-20. Wind WSW up to 10 MPH.

TUESDAY: Partly sunny. Chance of snow showers. Highs 28-35. Wind SW 5-15 MPH shifting to NW.

TUESDAY NIGHT: Partly cloudy. Lows 15-22. Wind NW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 32-39. Wind W 5-15 MPH.

DAYS 6-10 (DECEMBER 29 – JANUARY 2)

Temperature moderation heading through the last few days of 2022 with fair weather as high pressure moves off the coast, after which we get into some unsettled weather – likely rain, as a frontal system and low pressure area move through the region, to start the new year.

DAYS 11-15 (JANUARY 3-7)

A bit of an up and down temperature pattern during this period with a battle between the Southeast ridge and high pressure in eastern Canada seems to be shaping up. Typical La Nina pattern. Too soon to time any disturbances / unsettled weather.

DAYS 1-5 (DECEMBER 23-27)

The long-advertised storm is in progress, and behaving as expected with no surprises thrown at us. Expect some coastal flooding and additional wind damage with potential power outages especially in RI and eastern MA to the NH Seacoast region where wind gusts are strongest through mid morning, with coastal flooding issues through the late morning high tide cycle. The lull is on the way and then we get one or two more rounds of rain squalls in the area this afternoon as the cold front extending from rapidly deepening low pressure in the Great Lakes passes by. As the low lifts into eastern Canada through tonight, an arctic boundary will pass by and may produce some snow showers and even a brief snow squall in some areas. While we miss a widespread flash freeze due to the wind’s ability to dry many surfaces before temperatures fall rapidly below freezing, we still will have icy patches and also some scattered coatings of snow which can also briefly slick up some surfaces. But the ongoing wind and much drier air should sublimate much of the ice into morning – but use caution regardless. Wind chill becomes the deal for Saturday, and while most of the region is dry with just a slight chance of a passing snow flurry, the South Coast will see some ocean-effect snow which likely delivers a small accumulation. Christmas Eve and Christmas Day continue to be generally dry and quite cold, though the wind will start to settle down moving through Christmas Day and any lingering ocean effect snow showers will push away from the South Coast, leaving only the slightest chance of a snow flurry from Great Lakes snow shower remnants. High pressure brings dry and chilly weather Monday, and a weak disturbance may produce a few snow showers Tuesday as it moves through from west to east.

TODAY: Overcast morning with rain and embedded heavier rain showers with a slight chance of thunder, diminishing from southwest to northeast. Mostly cloudy midday and early afternoon with isolated showers and even a break of sun possible. Then heavier clouds and 1 or 2 rounds of moderate to heavy rain showers moving through from southwest to northeast through mid afternoon, again a slight chance of thunder. Clouds may break for a glimpse of sun, especially near and west of I-95, prior to sunset. Snow showers are possible central MA, southwestern NH, and eastern CT late day. Highs 53-60 this morning, falling to the 40s this afternoon. Wind SE 15-35 MPH, gusts 40+ MPH inland, 50+ MPH coastal areas, diminishing for a while, then shifting to SW at similar speeds but a shorter period of strong gusts through mid afternoon.

TONIGHT: Variably cloudy evening with snow showers possible – minor accumulation may occur. Rapid icing over of any wet surfaces. Partly cloudy overnight with additional snow showers developing South Coast. Lows 12-19. Wind SW 15-30 MPH with higher gusts. Wind chill below 10.

SATURDAY: Sun/cloud mix. Isolated to scattered snow showers possible, especially South Coast. Snow accumulation of up to 2 inches island and up to 1 inch South Coast. Highs 20-27. Wind SW 15-25 MPH, higher gusts. Wind chill around 10.

SATURDAY NIGHT (CHRISTMAS EVE): Partly cloudy. Isolated snow showers, but additional scattered snow showers in the South Coast region. Lows 12-19. Wind WSW 10-20 MPH. Wind chill below 10.

SUNDAY (CHRISTMAS): Partly cloudy. Isolated snow showers. Highs 23-30. Wind W 5-15 MPH, higher gusts. Wind chill below 20.

SUNDAY NIGHT: Clear. Lows 12-19. Wind W 5-15 MPH.

MONDAY: Sunny. Highs 26-33. Wind W up to 10 MPH.

MONDAY NIGHT: Mostly clear. Lows 13-20. Wind WSW up to 10 MPH.

TUESDAY: Partly sunny. Chance of snow showers. Highs 28-35. Wind SW 5-15 MPH shifting to NW.

DAYS 6-10 (DECEMBER 28 – JANUARY 1)

Quiet and cold middle of next week followed by moderation in temperature as we approach the change of year. May see wet weather to greet 2023, based on current timing and a more progressive Pacific-driven pattern evolving.

DAYS 11-15 (JANUARY 2-6)

May start with a bit of wet weather then drier and a cool down followed by moderation again and potential unsettled weather by the end of the period. Far too soon for any detail, but the overall pattern looks somewhat benign for early January.

DAYS 1-5 (DECEMBER 22-26)

On this first full day of winter, we look at the details of an upcoming storm. First we see clouds advance and thicken up today ahead of the system. Low pressure tracks into and through the Great Lakes while rapidly deepening through Friday. Between that and a strengthening high off to our northeast and east we will see a very strong pressure gradient. This is going to allow the wind to become strong in our region with the passage of this system. Two main bouts of precipitation will occur. The first one will take place with the system’s warm front, rain for most of the region from this evening to about mid morning Friday, when most of the expected 1 to 2 inches of rain will fall. A few areas may see amounts greater than 2 inches, while under 1 may occur on parts of Cape Cod. The strongest wind gusts are looking like they will take place from about 4 a.m. to about 10 a.m., when gusts of 45 to 65 MPH are possible, strongest being in eastern MA and RI coastal areas and higher elevations. This timing does reduce the chance of wind-driven coastal flooding as the high tide time is later in the day Friday, when we’ll be experiencing a lull in the strongest wind, and then a burst of wind from the southwest as the cold front moves through with a band of rain squalls. Once that goes by, we experience a rapid temperature drop from west to east. Thankfully, the continued wind and rapid drying of the air should help many surfaces dry off before they would have frozen up. But any puddles or areas that manage to remain wet will become icy rather rapidly during Friday evening. In addition, snow showers in the area behind the cold front may cause a small accumulation in some areas, which can add to the slippery conditions. One of our more dramatic temperature drops we’ve had in a while will take place – a matter of up to 40 degrees or so in just a couple hour’s time. This sets us up for a blustery and cold Christmas Eve and Christmas Day with a strong westerly air flow behind the departing storm which will be moving through eastern Canada. Saturday’s wind will be strongest, and Sunday’s will diminish slightly. Both days may see a few isolated snow showers surviving a trip from the Great Lakes, and on Saturday, the South Coast may pick up a bit of accumulating ocean-effect snow with a southwesterly wind – not too often a direction associated with ocean-effect snow in this area. By Monday, high pressure will bring cold but more tranquil weather to the region.

TODAY: Early limited sun, then cloudy. Highs 38-45. Wind E up to 10 MPH.

TONIGHT: Overcast. Rain arrives southwest to northeast, heavy at times overnight. Slight chance of thunderstorms after 3 a.m. Temperatures rising to 45-52. Wind E increasing to 10-20 MPH evening, SE 15-30 MPH with gusts over 40 MPH overnight, strongest coast.

FRIDAY: Mostly cloudy. Rain with embedded heavier rain showers and a slight chance of thunderstorms through mid morning, a lull, then a rain squall likely from southwest to northeast during the first half of the afternoon. Minor coastal flooding possible. Highs 53-60 occurring morning-midday, with a rapid drop beginning mid afternoon from southwest to northeast. Wind SE 20-35 MPH with gusts 45-65 MPH, strongest in higher elevations and coastal areas of eastern MA and RI, through mid morning, then diminishing slightly, then shifting to SW 15-35 MPH with gusts over 40 MPH.

FRIDAY NIGHT: Variably cloudy evening with snow showers possible – minor accumulation may occur. Rapid icing over of any wet surfaces. Partly cloudy to clear overnight. Lows 12-19. Wind SW 15-30 MPH with higher gusts.

SATURDAY: Sun/cloud mix. Isolated to scattered snow showers possible, especially South Coast. Highs 28-35. Wind SW 15-25 MPH, higher gusts.

SATURDAY NIGHT (CHRISTMAS EVE): Partly cloudy. Isolated snow showers. Lows 12-19. Wind WSW 10-20 MPH.

SUNDAY (CHRISTMAS): Partly cloudy. Isolated snow showers. Highs 27-34. Wind W 5-15 MPH, higher gusts.

SUNDAY NIGHT: Clear. Lows 12-19. Wind W 5-15 MPH.

MONDAY: Sunny. Highs 28-35. Wind W up to 10 MPH.

DAYS 6-10 (DECEMBER 27-31)

Current indications are for a quiet home stretch of 2022 with high pressure in control, starting with chilly weather followed by a moderating trend as high pressure shifts more to the south and east of New England with time.

DAYS 11-15 (JANUARY 1-5)

As 2023 arrives, watching the first couple days for a possible storm system bringing a rain threat with mild weather, then a return to dry weather and a more seasonable chill thereafter.

DAYS 1-5 (DECEMBER 21-25)

The winter solstice occurs at 4:48 p.m. today. High pressure area then moves over our area for a cold, bright and tranquil day. You will notice some high cloudiness at times today well in advance of our next storm system. These clouds thicken up tonight into Thursday. Developing and rapidly deepening the low pressure will move through the Great Lakes Thursday night and Friday bringing us a windy rain event which may start with some snowflakes in the higher elevations well to the Northwest of Boston and end as a mix or snow as a strong cold front sweeps through on Friday evening. Strong to damaging winds accompany this event. We will see some minor to moderate coastal flooding at the time of high tide due to astronomically high tides combined with strong wind. Areas that do not dry off with wind Friday night can experience a flash freeze with a rapidly dropping temperature. Cold and mainly dry weather with blustery conditions can be expected for the weekend – Christmas Eve and Christmas Day. We’ll have to watch for some snow showers that may survive their trip from the Great Lakes, and also a period of somewhat rare ocean-effect snow bands from southwest winds may occur along and near the South Coast Saturday. Dry weather and less wind is expected Monday with high pressure in control.

TODAY: Mostly sunny. Highs 33-40. Wind variable up to 10 MPH.

TONIGHT: Partly cloudy. Lows 22-29. Wind calm.

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

THURSDAY NIGHT: Cloudy. Rain arrives, may begin as snow/mix some inland locations. Lows 32-39 evening, likely warming overnight. Wind up to 10 MPH early, shifting to SE 5-15 MPH inland and 15-25 MPH coastal areas with higher gusts overnight.

FRIDAY: Mostly cloudy. Rain showers likely, some possibly heavy. Highs 55-62. Wind SE to S 15-35 MPH with gusts 40-55 MPH, possibly even higher in some coastal areas and higher elevations.

FRIDAY NIGHT: Mostly cloudy early evening with rain showers ending, possibly as snow showers with a brief coating of snow possible. Watch for rapid ice-over of wet surfaces by late evening / overnight. Partly cloudy to mostly clear overnight. Lows 20-27. Wind SW 15-35 MPH, higher gusts.

SATURDAY: Partly cloudy. Isolated to scattered snow showers possible, especially South Coast. Highs 28-35. Wind SW 15-25 MPH, higher gusts.

SATURDAY NIGHT: Partly cloudy. Isolated snow showers. Lows 12-19. Wind WSW 10-20 MPH.

SUNDAY (CHRISTMAS): Partly cloudy. Isolated snow showers. Highs 27-34. Wind W 5-15 MPH, higher gusts.

DAYS 6-10 (DECEMBER 26-30)

Generally dry and cold weather is expected much of the period. Watching for one wave of low pressure that may bring some snow or mix around December 27.

DAYS 11-15 (DECEMBER 31 – JANUARY 4)

Low confidence forecast. Indications of moderating temperatures early to mid period, a precipitation threat around the New Year, then a dry/colder finish.

DAYS 1-5 (DECEMBER 20-24)

A brisk northwesterly air flow continues today between low pressure in eastern Canada and high pressure approaching via the Great Lakes with a bright but chilly and breezy day for us. The high pressure area then moves over our area for a cold, bright and tranquil Wednesday for Winter Solstice (which occurs at 4:48 p.m.). But things change in a big way heading through Thursday and Friday as a rapidly deepening low pressure area moves through the Great Lakes, and its contrast with high pressure moving east of our region will create strong to powerful southeasterly to southerly winds here and a couple periods of rain, including some potential heavy rainfall. Thursday night to Friday evening. It will not likely rain the entire time though as there may very well be a couple dry periods in between bands. The final band will be on a strong cold front and may arrive quickly enough so that the rainfall ends as mixed precipitation or even snow, enough for a brief coating on some surfaces. More threatening is that areas that do not dry out from the wind can freeze over quickly later Friday night as the temperature drops rapidly, so keep that in mind if traveling later at night and early Saturday. Cold and mainly dry weather with blustery conditions can be expected for the weekend – Christmas Eve and Christmas Day. We’ll have to watch for some snow showers that may survive their trip from the Great Lakes, and also a period of somewhat rare ocean-effect snow bands from southwest winds may occur along and near the South Coast Saturday.

TODAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

TONIGHT: Mostly clear. Lows 16-23. Wind variable under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 33-40. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 22-29. Wind calm.

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

THURSDAY NIGHT: Cloudy. Rain arrives, may begin as snow/mix some inland locations. Lows 32-39 evening, likely warming overnight. Wind up to 10 MPH early, shifting to SE 5-15 MPH inland and 15-25 MPH coastal areas with higher gusts overnight.

FRIDAY: Mostly cloudy. Rain showers likely, some possibly heavy. Highs 55-62. Wind SE to S 15-35 MPH with gusts 40-55 MPH, possibly even higher in some coastal areas and higher elevations.

FRIDAY NIGHT: Mostly cloudy early evening with rain showers ending, possibly as snow showers with a brief coating of snow possible. Watch for rapid ice-over of wet surfaces by late evening / overnight. Partly cloudy to mostly clear overnight. Lows 20-27. Wind SW 15-35 MPH, higher gusts.

SATURDAY: Partly cloudy. Isolated to scattered snow showers possible, especially South Coast. Highs 28-35. Wind SW 15-25 MPH, higher gusts.

DAYS 6-10 (DECEMBER 25-29)

Breezy and cold Christmas Day with isolated snow showers possible otherwise dry weather. Generally dry and cold weather is expected through the middle portion of next week though keep an eye out for one possible disturbance with some snow showers.

DAYS 11-15 (DECEMBER 30 – JANUARY 3)

Low confidence forecast. Indications of moderating temperatures early to mid period, a precipitation threat around the New Year, then a dry/colder finish.

DAYS 1-5 (DECEMBER 19-23)

A northwesterly air flow dominates our weather today and Tuesday between eastern Canadian low pressure and central Canadian high pressure, bringing dry, breezy, and chilly weather. That high will sink southeastward and move across the region Wednesday, also a dry and chilly but more tranquil day as we lose the gusty breeze. Things change as we head later into the week. A complex low pressure system will be set to impact our region. First some lead energy develops an initial rain area along the Mid Atlantic Coast which then heads northward, reaching our region in the evening, but may start as snow/mix with some chilly air trapped in the area. While this is going on another low will take shape and rapidly deepen in the Midwest while heading for the Great Lakes. There are still some details about this system that remain unknown, such as how far west it tracks, which holds a key to how quickly the lingering cool air can be pushed out of our region, as it sometimes happens above us but not at the surface nearly as quickly, if at all, in this set-up. For now, I lean toward a warm front making it through, and Friday being a breezy and very mild day with rain showers, culminating in a rain squall line as a cold front sweeps across the region ahead of the rapidly deepening storm in the Great Lakes Friday evening. As for more precise timing, we’ll have to nail that down later in the week. The system will likely produce some significant and possibly damaging wind gusts.

MONDAY: Partly sunny. Highs 35-42. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 17-24. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 16-23. Wind variable under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 33-40. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 22-29. Wind calm.

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

THURSDAY NIGHT: Cloudy. Rain arrives, may begin as snow/mix some inland locations. Lows 32-39 evening, likely warming overnight. Wind up to 10 MPH early, shifting to SE 5-15 MPH inland and 15-25 MPH coastal areas with higher gusts overnight.

FRIDAY: Mostly cloudy. Rain showers likely. Highs 55-62. Wind SE 15-25 MPH with higher gusts.

DAYS 6-10 (DECEMBER 24-28)

A blustery, cold Christmas Eve & Christmas Day can be expected in the wake of powerful low pressure moving through eastern Canada. A few snow showers may survive a trip from the Great Lakes into our region. Generally dry and cold weather is expected early to middle portion of next week but watching around December 27 for a potential snow/mix/rain threat.

DAYS 11-15 (DECEMBER 29 – JANUARY 2)

Not a high confidence forecast, but after a chilly start it may moderate with a rain or snow threat sometime around the beginning of 2023.

The weekly…

DAYS 1-5 (DECEMBER 18-22)

Upper level low pressure crosses the region today with a gusty breeze, some clouds, and maybe a few passing snow flurries. Monday and Tuesday will be breezy and chilly days with an air flow out of Canada between low pressure in eastern Canada and high pressure approaching via the Great Lakes. This high will move over our region with dry, cold, tranquil weather on Wednesday. We’ve been watching a window of time where we are vulnerable to stormy weather on December 22 and 23, and that’s still there. While not set in stone, it’s starting to look like we’ll be looking at a rapidly strengthening low pressure moving into the Great Lakes by later Thursday, and during that day here we’ll see clouds thicken up, along with milder air arriving, so that we are probably looking at a rain event beginning by that night. Still will have to fine-tune some details about this system is we get closer to it.

TODAY: Variably cloudy. A passing snow flurry possible especially this afternoon. Highs 33-40. Wind NW 5-15 MPH, higher gusts.

TONIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 35-42. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 17-24. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 16-23. Wind variable under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 33-40. Wind variable up to 10 MPH.

WEDNESDAY NIGHT: Partly cloudy. Lows 22-29. Wind calm.

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

DAYS 6-10 (DECEMBER 23-27)

Stormy weather on December 23 should be in the form of rain and rain showers with gusty wind and mild air as strong low pressure passes northwest of the region. Christmas Eve and Christmas Day look blustery, cold, and mainly dry, perhaps a passing snow shower at times, behind this system as it exits through eastern Canada. Watching for a quick moving disturbance from Canada with a snow shower or light snow threat by the end of the period with continued chilly late December conditions.

DAYS 11-15 (DECEMBER 28 – JANUARY 1)

Starting chilly with mostly dry weather, maybe a brief light snow threat from a passing disturbance, then a few hints of a quick moderation in temperature toward the New Year’s Eve / New Year’s Day time frame.

DAYS 1-5 (DECEMBER 17-21)

The slow process of saying goodbye to our current bout of unsettled weather is underway. This storm was noted for producing plenty of rain and wind for the coastal plain, and a significant snow for the highest elevations of the WHW forecast area (southwestern NH and far north central MA). As we have expected, the colder air is filtering back eastward into the coastal plain where rain showers have becoming mixed with or changed to snow showers. We’ve lost the steadiest and heavier precipitation though, so just minor dustings / coatings of snow will occur with some of these snow showers. The general trend will be for drying, but we’ll hang onto the cloud cover through the day, seeing that break up more tonight. Sunday looks like a chilly but mainly dry day – only the chance of a few passing light snow showers in response to upper level low pressure moving through the region. Then, as we come down the home stretch of autumn toward the winter solstice, which occurs Wednesday at 4:48 p.m., we will be in a chilly but mainly dry weather pattern with high pressure providing plenty of low-angle sun Monday and Tuesday. Wednesday may some intervals of clouds and perhaps a later-day or evening snow shower associated with a passing trough, but this will be a very minor system with no significant impact.

TODAY: Mainly cloudy – rain and snow showers at times until midday favoring southeastern NH, eastern MA, and RI. Highs 35-42. Wind W 10-20 MPH, higher gusts.

TONIGHT: Partly cloudy. Lows 22-29. Wind NW 10-20 MPH.

SUNDAY: Partly sunny. A passing snow shower possible. Highs 33-40. Wind NW 5-15 MPH, higher gusts.

SUNDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 35-42. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 17-24. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

TUESDAY NIGHT: Mostly clear. Lows 16-23. Wind W 5-15 MPH.

WEDNESDAY: Partly cloudy. A late day snow shower possible. Highs 33-40. Wind W 5-15 MPH.

DAYS 6-10 (DECEMBER 22-26)

Likely impact by a storm system later December 22 into December 23 but highly uncertain of storm track and resultant weather here – stay tuned. Generally dry and cold pattern thereafter but may be a minor snow/mix producer right around Christmas Day.

DAYS 11-15 (DECEMBER 27-31)

Still a low confidence forecast but overall pattern looks chilly with one or two precipitation chances but overall on the dry side heading down the home stretch of 2022.

DAYS 1-5 (DECEMBER 16-20)

A rain event for most – except some higher elevation snow well inland (southwestern NH to parts of north central MA) today. This occurs as a redeveloped low wraps up just south of our region then moves to just east of the region by Saturday, at which time colder air moves back in and rain ends as snow showers for some areas. Upper level low pressure still has to cross the region Sunday with a few more snow showers possible, then high pressure noses back in for cold and dry weather early next week.

TODAY: Cloudy with rain likely, except snow with additional accumulation possible in highest elevations of north central MA through southwestern NH. Areas of fog. Highs 38-45 north and west of Boston, 45-52 Boston southeastward, mildest over Cape Cod and Islands. Wind E 10-20 MPH, gusts 25-35 MPH, strongest coast, may shift to S late day over Cape Cod and Islands.

TONIGHT: Overcast with rain likely through the evening hours, tapering off to rain showers overnight. Lows 35-42. Wind briefly variable around Cape Cod otherwise E to NE 10-20 MPH with higher gusts evening, shifting to W overnight.

SATURDAY: Mostly cloudy. Rain showers turning to snow showers west to east before tapering off. Some minor accumulation of snow is possible in portions of southern NH and northern MA. Highs 38-45 early, then turning colder. Wind W to NW 10-20 MPH, higher gusts.

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

SUNDAY: Partly sunny. A passing snow shower possible. Highs 33-40. Wind NW 5-15 MPH, higher gusts.

SUNDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 35-42. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 17-24. Wind NW 5-15 MPH.

TUESDAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

DAYS 6-10 (DECEMBER 21-25)

Still watching the window of December 22-23 for a potential storm, and with medium range guidance showing a large spread of outcomes, there is a lot of uncertainty and it remains impossible to attempt any detailing whatsoever, other than to say the signal is there for an East Coast storm system pre-Christmas, with mostly dry and cold weather both before and after it.

DAYS 11-15 (DECEMBER 26-30)

Overall pattern looks cold with one or two precipitation chances, but with uncertainties before this, the confidence becomes even lower for this period.

DAYS 1-5 (DECEMBER 15-19)

Our block goes on and the long-talked-about storm system at the end of the week is almost here, since it’s almost the end of the week! No changes from yesterday’s thought process, so this is basically a repeat of that. Elongating low pressure redevelops off the northern Mid Atlantic Coast and tracks just south of New England, possibly over the Islands and Outer Cape Cod through Friday to a position just east of New England Saturday, before moving away, with upper level low pressure still to swing through during the weekend. The unsettled results will be re-outlined in the detailed forecast section below. Still looking for dry, chilly weather to start next week.

TODAY: Mostly cloudy. Highs 36-43. Wind NE to E 5-15 MPH.

TONIGHT: Thickening clouds. Rain arriving overnight, may start as snow away from the coast, especially higher elevations of central MA and southwestern NH where a coating to 1 inch of snow may fall initially. Lows 31-38 evening followed by a slow temperature rise overnight. Wind E 10-20 MPH, gusts 25-35 MPH, strongest coastal areas.

FRIDAY: Cloudy with rain likely. Areas of fog. Highs 38-45 north and west of Boston, 45-52 Boston southeastward, mildest over Cape Cod and Islands. Wind E 10-20 MPH, gusts 25-35 MPH, strongest coast, may shift to S late day over Cape Cod and Islands.

FRIDAY NIGHT: Overcast with rain likely through the evening hours, tapering off to rain showers overnight. Lows 35-42. Wind briefly variable around Cape Cod otherwise E to NE 10-20 MPH with higher gusts evening, shifting to W overnight.

SATURDAY: Mostly cloudy to partly sunny. Rain showers may turn to snow showers from west to east before ending. Highs 38-45 morning, then turning colder. Wind W to NW 10-20 MPH, higher gusts.

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

SUNDAY: Partly sunny. A passing snow shower possible. Highs 33-40. Wind NW 5-15 MPH, higher gusts.

SUNDAY NIGHT: Partly cloudy. Lows 22-29. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 35-42. Wind NW 5-15 MPH.

DAYS 6-10 (DECEMBER 20-24)

Mainly dry, seasonably cold for the first couple days of this period. Keeping an eye on the December 22-23 period for a potential storm system in which it’s far to soon to discuss any details. Cold with lingering snow showers for Christmas Eve assuming current timing is correct.

DAYS 11-15 (DECEMBER 25-29)

One or two potential disturbances with precipitation chances, otherwise mostly dry with temperatures averaging below normal. Will be able to go into more detail on the late days of December soon.

DAYS 1-5 (DECEMBER 14-18)

Large scale blocking goes on, driven by Canadian high pressure. A large offshore storm pushed a cold front through the region overnight, accompanied by snow showers, which coated the ground in some places, but much of that then blew into crevices by strong winds behind the front. The gusty winds will continue today but with lots of sun and passing clouds. A few of these clouds may produce a snow flurry, but the better chance of this will be over Cape Cod. It will feel quite a bit colder than yesterday, even though the temperature is only slightly lower, due to the stronger wind and resultant wind chill effect. The gusty wind keeps up this evening then starts to relax overnight while shifting to northeast as low pressure to the east starts to lose influence and high pressure to the north drives the air flow. With time, that will combine with the air flow around the approaching low from the southwest, turning the wind more easterly as Thursday goes on. This brings in ocean stratus, while clouds from the approaching low will be coming in above those, so Thursday turns out to have little or no sun. Low pressure is set to track just south of our region on Friday, an elongation / redevelopment of an initial storm that was entering the Great Lakes region, as described in previous discussions. It’s pretty apparent now that this will be a mainly rain event for the WHW forecast area, although there could be some snow with a bit of accumulation at the start over interior higher elevations of central MA to southwestern NH, but too much mild air from the ocean means all areas are rain for the bulk of the event. There may be a decent temperature contrast on Friday, as the storm’s main precipitation shield passes through, depending on the exact track of low pressure. If it comes up across far southeastern MA, a quick jump to 50+ temps may occur over Cape Cod and the Islands, while it’s quite a bit cooler off to the north and west. As low pressure pulls away on Saturday, improvement will be slow to occur, and the return of colder air means that precipitation can switch from rain back to snow …. however … this will be taking place after the main precipitation has departed, so I am only expecting a transition from lingering rain showers to snow showers. Colder air moves in for Sunday but the passage of upper level low pressure and a trough that was once the initial storm means a few snow showers may occur. Otherwise expecting a mainly dry Sunday.

TODAY: Sun, occasional passing clouds. A few snow showers possible near eastern coastal MA but especially Cape Cod. Highs 32-39. Wind N 10-20 MPH, higher gusts.

TONIGHT: Mostly clear evening. Partly to mostly cloudy overnight. Lows 25-32. Wind N 10-20 MPH early, becoming NE 5-15 MPH.

THURSDAY: Mostly cloudy. Highs 36-43. Wind NE to E 5-15 MPH.

THURSDAY NIGHT: Thickening clouds. Rain arriving overnight, may start as snow away from the coast, especially higher elevations of central MA and southwestern NH where a coating to 1 inch of snow may fall initially. Lows 31-38 evening followed by a slow temperature rise overnight. Wind E 10-20 MPH, gusts 25-35 MPH, strongest coastal areas.

FRIDAY: Cloudy with rain likely. Areas of fog. Highs 38-45 north and west of Boston, 45-52 Boston southeastward, mildest over Cape Cod and Islands. Wind E 10-20 MPH, gusts 25-35 MPH, strongest coast, may shift to S late day over Cape Cod and Islands.

FRIDAY NIGHT: Overcast with rain likely through the evening hours, tapering off to rain showers overnight. Lows 35-42. Wind briefly variable around Cape Cod otherwise E to NE 10-20 MPH with higher gusts evening, shifting to W overnight.

SATURDAY: Mostly cloudy to partly sunny. Rain showers may turn to snow showers from west to east before ending. Highs 38-45 morning, then turning colder. Wind W to NW 10-20 MPH, higher gusts.

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

SUNDAY: Partly sunny. A passing snow shower possible. Highs 33-40. Wind NW 5-15 MPH, higher gusts.

DAYS 6-10 (DECEMBER 19-23)

A dry, cold pattern is expected for a good portion of the week leading up to Christmas, but we’ll be watching for low pressure to impact the region late in the week – far too soon to speculate on any details with this possible system.

DAYS 11-15 (DECEMBER 24-28)

One or two potential disturbances with precipitation chances, otherwise mostly dry with temperatures averaging near to below normal.

DAYS 1-5 (DECEMBER 13-17)

Not making any changes to the ongoing forecast at this point in time. Large scale blocking pattern continues as high pressure sits to our north and northeast. A large low pressure area to our east will do a loop and at its closest pass helps initiate some snow showers, especially across Cape Cod, Wednesday. Low pressure heads for the Great Lakes Thursday, energy elongates, and new low pressure forms off the northern Mid Atlantic Coast Thursday night and Friday. While the exact track of that low is still TBD, it will likely bring a good swath of moisture across our region during this time frame, with odds favoring rain in coastal areas and rain/mix/snow further inland with mix/snow more likely in higher elevations. Still can’t detail it more than that. Will be able to add more detail tomorrow and certainly by Thursday morning’s update. I do expect precipitation to linger into early Saturday from the first part of the system…

TODAY: Mostly sunny. Highs 33-40. Wind NW 5-15 MPH.

TONIGHT: Partly cloudy. Lows 16-23. Wind N 5-15 MPH, higher gusts.

WEDNESDAY: Sun and passing clouds. Possible snow showers near eastern coastal areas especially Cape Cod. Highs 32-39. Wind N 10-20 MPH, higher gusts.

WEDNESDAY NIGHT: Partly cloudy early, then mostly clear. Lows 16-23. Wind N to NW 5-15 MPH.

THURSDAY: Sun followed by clouds. Highs 36-43. Wind N to NE up to 10 MPH.

THURSDAY NIGHT: Thickening clouds. Rain arriving overnight, may start as snow away from the coast. Lows 31-38 evening, may rise overnight. Wind E to SE 10-20 MPH.

FRIDAY: Cloudy with rain likely, but some mix/snow possible interior higher elevations. Highs 38-45 north and west of Boston, 45-52 Boston southeastward. Wind SE 10-20 MPH, higher gusts.

FRIDAY NIGHT: Overcast with rain likely but some mix/snow possible interior areas especially higher elevations. Lows 32-39. Wind E to NE 10-20 MPH, higher gusts.

SATURDAY: Cloudy start with rain except mix/snow possible interior higher elevations, then breaking clouds with a possible rain or snow shower. Highs 39-46 by midday but turning colder during the afternoon. Wind variable becoming N to NW 10-20 MPH, higher gusts.

DAYS 6-10 (DECEMBER 18-22)

Upper level low pressure crosses the region December 18 with a few snow showers possible. Generally dry and chilly weather is expected early to middle of next week then may have to watch a system for a precipitation threat by the end of the period.

DAYS 11-15 (DECEMBER 23-27)

One or two potential disturbances with precipitation chances, otherwise mostly dry with temperatures averaging near to below normal.
