DAYS 1-5 (FEBRUARY 28-MARCH 4)
On this final day of February we are setting the departure of a relatively minor snow event, but one of our only all snow events all season. The system behaved about as expected with a 2-5 inch snow forecast and a 1-4 inch result (pending some final snow reports). And now we turn our attention to the upcoming threats, and there are several. You have been pre-warned that the early part of March would feature colder weather and some storm threats, and this combination naturally leads to more snow threats, in theory, but does not guarantee that we are suddenly going to be in a snowy pattern just the same. Each of these events will have their own little quirks and variations, which will will try to work out as they get closer in time range. We still are having the issue with a pattern that doesn’t allow model forecast to be that dependable for very long out from the initial time, so nothing concrete should be said about each of these events until the details are adequately clear, and that method will be adhered to here on the blog. Friday’s event will not really be much of an event at all for most of the region, bringing just clouds, as it will be a disturbance passing mainly south of the region bringing only the threat of insignificant precipitation to the southernmost portions of southeastern New England. Saturday’s event still carries some uncertainty, but I am leaning toward 2 systems staying mainly separated, with a mainly offshore system that has the risk of bringing a period of steadier snow and rain to Cape Cod, and a weaker frontal system that should bring some mix/snow showers through the region west to east later Saturday to early Sunday. Many media outlets are already sounding a little too certain in my opinion about a threat for Sunday night and Monday. To me, the pattern certainly looks now like it wants to produce something that will make a run at the region, but the track is uncertain enough that anything from a snow to rain event, to a snow event, to a graze or miss can all still be considered possible. One thing I am more certain of is whatever form and location this system is in, it will be a fast mover and of relatively short duration. So based on the uncertainty, the wording in the detailed forecast below won’t be very detailed. Have to work with the limitations here.
Forecast details…
TODAY: Mostly cloudy through mid morning with bands of snow lingering near the eastern MA coast with some additional light accumulation. Partly sunny late morning on with isolated snow showers. Highs 28-35. Wind NE to N 5-15 MPH.
TONIGHT: Partly cloudy. Lows 18-25. Wind light N to NW.
FRIDAY: Mostly cloudy. Risk of rain/snow showers favoring eastern CT, RI, and southeastern MA. Highs 35-42. Wind variable 5-15 MPH.
FRIDAY NIGHT: Partly cloudy. Lows 25-32. Wind light variable.
SATURDAY: Mostly cloudy. A period of rain or snow possible Cape Cod. Mix/snow showers possible late day or evening from west to east. Highs 35-42. Wind variable 5-15 MPH.
SUNDAY: Variably cloudy. Chance of snow/mix at night. Lows from the middle 20s to lower 30s. Highs from the middle to upper 30s.
MONDAY: Mostly cloudy. Chance of snow/mix/rain early. Chance of mix/snow showers after. Temperatures generally steady 30s to around 40.

DAYS 6-10 (MARCH 5-9)
Dry weather expected to start and end the period, but the March 6-8 period may see 1 or 2 disturbances bring the threat of precipitation. Temperatures near to below normal.

DAYS 11-15 (MARCH 10-14)
Colder, drier to start the period. Risk of some precipitation mid period then a warm-up may follow this as the pattern relaxes allowing the jet stream to lift to the north and possible some high pressure to locate itself on the East Coast.

7:22AM

DAYS 1-5 (FEBRUARY 27-MARCH 3)
The only pure snow event of meteorological winter will occur on its final day (starting the day before, technically), as a wave of low pressure will run into plenty of cold air and produce a general light to borderline moderate snowfall from late this evening into Thursday. The snow event will be largely over by or during Thursday’s morning commute although some ocean-effect snow showers may linger along the Massachusetts coastline, where we are most likely to realize the higher end of my expected 2-5 inch range, while areas from the Merrimack Valley into southern NH, due to drier air, and areas close to the South Coast, due to a shorter-duration of snow, may be closer to the lower ends of the totals. It will take very little difference in melted precipitation to make a difference of an inch or two in total snowfall as this will be a fairly high snow to water ratio event anyway. Once again, it’s not so much about the exact amount of snow any given area will be seeing, but timing, with regards to impact, as the event will be occurring and wrapping up prior to and during a weekday morning commute. But at least without the mess of varying types of precipitation, rapid temperature changes, and wind, this will be a relatively easy event to manage. But no matter how simple the event, it’s always very smart to use caution when traveling. Please do so. The remainder of the forecast has a few adjustments, as it looks like the Friday disturbance will be fairly weak and barely carry enough moisture to produce a touch of rain and/or snow in southern areas. The dilemma, if you will, is how the weekend system will behave. All guidance has struggled with exactly what to do with this. My idea of a couple days ago of 2 nearly separate systems, one to the south, one to the north, may now be the most likely scenario, essentially resulting in a frontal passage here at the mid point of the weekend, with an episode of rain and/or snow showers. Precipitation type may be hard to know until shortly before the event due to marginal temperatures. So there is yet more fine-tuning to do with that one, which seems bound to be hard to figure out until virtually the last moment. Oh well!
Forecast details…
TODAY: Sunshine followed by increasing cloudiness. Highs 25-32. Wind light variable.
TONIGHT: Cloudy. Snow arrives west to east late evening and continues overnight. Lows 18-25. Wind light N to NE.
THURSDAY: Mostly cloudy start with lingering snow especially southeastern MA, total accumulation 2-5 inches with the lower end of the range most likely in southern NH and the Merrimack Valley of MA, and the higher end of the range most likely from Boston to Plymouth to Providence, and another area of lower end amounts possible closer to the South Coast including Cape Cod. Highs 28-35. Wind NE to N 5-15 MPH.
THURSDAY NIGHT: Partly cloudy. Lows 18-25. Wind light N to NW.
FRIDAY: Variably cloudy. Risk of rain/snow showers favoring eastern CT, RI, and southeastern MA. Highs 35-42. Wind variable 5-15 MPH.
SATURDAY: Early sun then clouding up. PM rain or snow showers. Lows from the upper 20s to lower 30s. Highs in the 40s.
SUNDAY: Clouds and a risk of light mix/snow early, then partly sunny with isolated snow showers. Temperatures generally steady in 30s. Becoming windy.

DAYS 6-10 (MARCH 4-8)
Disturbance brings clouds and a risk of a few snow showers March 4. Dry and chilly March 5. Watching the March 6-8 period for one or two storm systems that may impact the region with rain/mix/snow.

DAYS 11-15 (MARCH 9-13)
A shot of cold air to start the period and then a moderating trend seems more likely with a minor precipitation event around mid period otherwise mainly dry.

7:16AM

DAYS 1-5 (FEBRUARY 26-MARCH 2)
If you didn’t blow away yesterday and are still here to read this, you made it through the big wind event, or were not around the area for it. Quite the event I won’t dwell on here as we’ve all pretty much read the stories or seen the pictures / video. I even had my own experience with a fairly near-miss with a portion of a tree coming down on the road I was heading toward. We’re actually not quite done with the event, as there will still be some wind gusts today that would be considered quite a windy day, but much weaker than yesterday’s. This continues to be in response to the large pressure gradient between the big high pressure area from central Canada to the upper Midwest and a broad and powerful low pressure area in the Canadian Maritimes. But by late today this gradient finally relaxes enough to put an end to this event, leaving us with a decent cold air mass which will send many temperatures below 10 for the early hours of Wednesday, and set us up with plenty of cold to assure the next system will be a snow-producer. This will be the result of a clipper low pressure area from Canada coming across the Great Lakes and heading just south of New England by early Thursday. This late Wednesday night / Thursday morning snow event will be minor, in terms of snow amounts, but will be timed to cause some issues with the Thursday morning commute. The system will be fighting dry air, and that along with its quick movement and somewhat limited moisture will keep most snow amounts under 4 inches, but 4 will be upper limit of my range as I think it can possibly be reached, especially in southeastern MA where a period of onshore wind during and even after the main precipitation shield passes can add a tad to the totals. Either way, later Thursday, it’s all gone, but we don’t get too much of a breather as the active pattern rolls on, and we’ll have a rain/snow shower threat Friday from a passing disturbance and another low pressure which tracks into the eastern Great Lakes Saturday and spawns a secondary just southwest of New England which then travels over the region, bringing milder air and a mainly rain event.
Forecast details…
TODAY: Sunny. Highs 23-30. Wind W 15-25 MPH with gusts 35-45 MPH.
TONIGHT: Clear. Lows 8-15. Wind W 10-20 MPH with higher gusts evening, diminishing overnight.
WEDNESDAY: Sunshine followed by increasing cloudiness. Highs 25-32. Wind light variable.
WEDNESDAY NIGHT: Cloudy. Snow arrives west to east late evening and continues overnight. Lows 18-25. Wind light N to NE.
THURSDAY: Mostly cloudy start with lingering snow especially southeastern MA, total accumulation 2-4 inches though may be just 1-2 inches far northeastern MA and southern NH, and best chance of 4-inch amounts in southeastern MA. Becoming partly sunny midday and afternoon but still a passing snow shower possible. Highs 28-35. Wind NE to N 5-15 MPH.
FRIDAY: Variably cloudy. Risk of rain/snow showers. Lows in the 20s. Highs from the middle 30s to lower 40s.
SATURDAY: Early sun then clouding up. PM rain. Lows from the upper 20s to lower 30s. Highs in the 40s.

DAYS 6-10 (MARCH 3-7)
Departing low pressure brings, wind, colder air, and a risk of a few snow showers March 3. Disturbance brings clouds and a risk of a few snow showers March 4. Dry and chilly March 5. Another low pressure area threatens with rain/mix/snow March 6 and/or 7.

DAYS 11-15 (MARCH 8-12)
The weather pattern will continue to allow colder air to dominate and a risk of 1 or 2 mix/snow events during this period.

6:03AM

DAYS 1-5 (FEBRUARY 25-MARCH 1)
The first day of March has made it into the first blog forecast period! That means spring’s coming right? Well yes, spring’s coming, but not soon. If you have lived in New England for any amount of time beyond a year or two, you’ll out yourself in short order that March is not a spring month more than it is a winter month. But I’m getting way ahead of myself, we still have 4 days left in February, and those won’t be anything like spring either. First, it’s high wind Monday, the event we’ve now talked about for a few days leading up to today, and it will deliver in the form of powerful gusts of wind during a day of sustained moderate to occasionally strong westerly winds. The peak wind will occur in the 12 hour period from about 7AM to about 7PM, but don’t go exactly by the clock, as some areas have already been seeing decent wind gusts, and they will also continue to occur right through tonight and even into Tuesday, only gradually subsiding. It goes without saying that in the aging forest we live in, tree damage and resultant power outages and property damage are possible. The cause of the wind is the pressure gradient between large sized and powerful low pressure in eastern Canada and elongated high pressure from central Canada into the upper Midwest. With these large features moving only slowly eastward, it makes for an extended period of wind. I should also mention that as these winds ramp up this morning, a few snow showers have made it into the region, and though localized and not lasting too long, they could briefly cause reduced visibility where they do occur, so if traveling be on the look out for these this morning. A decent shot of cold air will also be coming in with this wind event and it will be quite cold by tonight right through Wednesday. After dry weather Tuesday and most of Wednesday, a clipper low pressure system will dive across the Great Lakes and across southern New England Wednesday night and early Thursday. This should be a minor snow event for most, but just enough mild air may be drawn into the southern portion of the system for a South Coast mix, so snow amounts could be a little less there. More dry, chilly air follows later Thursday and a small disturbance coming along on Friday may deliver a few rain/snow showers as March arrives.
Forecast details…
TODAY: Partly sunny. Isolated snow showers this morning may briefly reduce visibility and cause localized coatings of snow that will melt and dry after. Highs 30-37. Wind W 15-35 MPH with gusts 45-65 MPH.
TONIGHT: Partly cloudy evening. Clear overnight. Lows 13-20. Wind W 15-30 MPH with gusts 40-60 MPH, diminishing slightly overnight.
TUESDAY: Sunny. Highs 23-30. Wind W 15-25 MPH with gusts 35-45 MPH.
TUESDAY NIGHT: Clear. Lows 8-15. Wind W 10-20 MPH with higher gusts evening, diminishing overnight.
WEDNESDAY: Sunshine followed by increasing cloudiness. Accumulating snow probable at night. Highs 25-32. Wind light variable.
THURSDAY: Cloudy morning with snow and possible South Coast mix early. Partly sunny afternoon. Temperature rise into the 30s then steady.
FRIDAY: Variably cloudy. Risk of rain/snow showers. Lows in the 20s. Highs from the middle 30s to lower 40s.

DAYS 6-10 (MARCH 2-6)
Low pressure likely to track through the Great Lakes and into eastern Canada during the March 2-3 weekend bringing milder air and a risk of rain showers Saturday, windy and colder weather with a risk of snow showers Sunday. Upper disturbance brings cloudiness and a risk of a few snow flurries March 4 followed by dry and chilly weather March 5. Next system threatens with a chance of snow/mix by the end of the period.

DAYS 11-15 (MARCH 7-11)
The weather pattern allows colder air to dominate and a risk of 1 or 2 mix/snow events during this period.

6:52AM

DAYS 1-5 (FEBRUARY 24-28)
10 days ago I noticed my first sign that we may be influenced by a broad Pacific storm system that would likely be a mainly rain-producer. Given the theme of the winter overall, despite some atmospheric indices being favorable for snow events, it is not a surprise that this initial thought turned out to be correct. It is that storm system that impacts us today with our rainfall, but not really all that much rain in comparison to some of the systems we have endured since last autumn, with many areas coming in at under 1/2 inch of rain for this event. Of more note are the winds that are coming as this system departs, and will keep themselves up throughout Monday and even into Tuesday to some degree. The wind will be caused by the fairly tight pressure gradient between the departing low, which will be quite deep, and a fairly strong high pressure area to its and our southwest. We’ll be in the middle or “in the wind zone”. We’ll have to watch for weakened tree limbs and in some cases entire trees that are vulnerable to such events. Scattered power outages are possible. Along with the drier weather and wind will come colder air as well, although this is not going to be arctic cold, just fairly typical late winter cold. When we get to midweek, or the final 2 days of February, we’ll watch a weak system driving out of Canada. This clipper-type system may bring a period of snow/mix to the region in the late Wednesday to Thursday time period.
Forecast details…
TODAY: Cloudy with rain likely, except freezing rain until mid morning central MA and interior southern NH, tapering to rain showers later. Highs 40-47. Wind light N to NE over interior areas early, SE 5-15 MPH elsewhere, then SE to S increasing to 15-25 MPH all areas midday shifting to W during the afternoon from west to east.
TONIGHT: Breaking clouds. Lows 28-35. Wind W 15-30 MPH, gusts 35-50 MPH.
MONDAY: Sun and passing clouds. Highs 37-44. Wind W 20-35 MPH, gusts 45-60 MPH.
MONDAY NIGHT: Clear. Lows 15-22. Wind W 15-30 MPH, gusts 40-55 MPH.
TUESDAY: Sunny. Highs 33-40. Wind W 10-25 MPH, gusts 30-45 MPH, gradually diminishing.
WEDNESDAY: Clouding up. Nighttime snow/mix possible. Lows in the 10s. Highs in the 30s.
THURSDAY: Mostly cloudy. Snow/mix possible mainly morning. Temperatures steady in the 30s.

DAYS 6-10 (MARCH 1-5)
Been keeping an eye on the early days of March for both potential visits from cold air from Canada and possible storminess. Nothing has changed, but timing is still very uncertain on how things evolve. March 1 enters the 5-day forecast period tomorrow and will detail it then, and try to fine-tune the other days as much as possible.

DAYS 11-15 (MARCH 6-10)
We remain vulnerable to both cold and possible storminess during this period, but far too soon to see anything in detail. Storm track may remain split with bigger events being suppressed to the south.

8:40AM

COMMENTARY
The challenge it has been to forecast medium and longer range stuff the last several months has been more fun than frustrating to me. It’s an approach I must take to this science otherwise it would drive me nuts. And now I wonder if that cold/dry regime I have been expecting which the “negative PNA” and “elusive MJO” have been making me look like a fool waiting for my finally be coming … in March. But then again, maybe it’s just another dangling carrot. Oh well, one step at a time, starting with the next 5 days first. Read on…

DAYS 1-5 (FEBRUARY 23-27)
High pressure retreats today, which will still be a nice day. Low pressure cranks up and tracks through the Great Lakes Sunday, bringing what will be mainly a rain event to the region, however it may start as snow/sleet briefly in the pre-dawn hours as just enough cold hangs on initially. Another thing to watch for will be pockets of freezing rain in central MA and southwestern NH especially in elevated valleys where cold air will hang on the longest before being scoured out. The now well-advertised windy Monday will indeed be occurring as what will be a monster-sized low pressure circulation slowly moves through eastern Canada Monday into Tuesday. The strongest winds will be Monday, but they will still be gusty through Tuesday. And then it’s “wildcard Wednesday” as the next low pressure area moves into the region. Model forecasts, as expected, have been all over the place with this during the course of the last several days, and as it gets closer and now in the 5-day range it looks like an unimpressive but possibly frozen event. Still some details to work out on this over the next couple days, so will leave forecast wording vague for now.
Forecast details…
TODAY: Sun and high clouds. Highs 37-44. Wind light variable.
TONIGHT: Thickening overcast. Rain arrives pre-dawn, may start as snow/sleet in some areas especially interior MA and southern NH. Lows 30-37 early. Wind light SE.
SUNDAY: Cloudy with rain likely, tapering to rain showers later. Pockets of freezing rain possibly early in elevated valleys of central MA and southwestern NH. Highs 40-47. Wind SE 15-25 MPH and gusty, shifting to W at the end of the day.
SUNDAY NIGHT: Breaking clouds. Lows 28-35. Wind W 15-30 MPH, higher gusts.
MONDAY: Sun and passing clouds. Highs 37-44. Wind W 15-30 MPH, gusts 40-55 MPH.
TUESDAY: Sunny. Breezy. Lows in the 10s. Highs in the 30s.
WEDNESDAY: Clouding up. PM snow/mix possible. Lows in the 10s. Highs in the 30s.

DAYS 6-10 (FEBRUARY 28-MARCH 4)
Midweek system departs early February 28 as snow/mix/rain (uncertain at this point on precipitation type). Will watch the first 4 days of March for at least one more storm threat but to be honest I am not even close to confident about timing and details so will leave it at that for today and attempt a little more tuning tomorrow.

DAYS 11-15 (MARCH 5-9)
We remain vulnerable to both cold and possible storminess during this period, but far too soon to see anything in detail. Storm track may remain split with bigger events being suppressed to the south.

7:17AM

DAYS 1-5 (FEBRUARY 22-26)
High pressure moves in today and hangs on Saturday with 2 fairly nice late winter days. Low pressure tracks into the Great Lakes Sunday spreading a large precipitation shield into the region, just about all of it in the form of rain, though there may be some snow/sleet at the start later Saturday night, especially over interior areas. This storm will be very large and fairly powerful as it exits via eastern Canada Monday, and the pressure gradient between it and high pressure approaching from the west will get the winds roaring in the region during Monday, but with dry weather. That low will be so broad in scope that its influence will still be with us through Tuesday with more cold and a gusty breeze.
Forecast details…
TODAY: Mostly sunny. Highs 36-43. Wind NW 5-15 MPH, diminishing late.
TONIGHT: Mostly clear. Lows 18-25. Wind light variable.
SATURDAY: Sun and high clouds. Highs 37-44. Wind light variable.
SATURDAY NIGHT: Thickening overcast. Rain arrives, may start as snow/sleet in some areas especially interior MA and southern NH. Lows 30-37 early, then rising slowly overnight. Wind light SE.
SUNDAY: Cloudy with rain likely, tapering to rain showers later. Highs 40-47. Wind SE 15-25 MPH and gusty, shifting to W at the end of the day.
MONDAY: Sun/clouds. Windy. Lows from the upper 20s to lower 30s. Highs from the upper 30s to lower 40s.
TUESDAY: Sunny. Breezy. Lows in the 10s. Highs in the 30s.

DAYS 6-10 (FEBRUARY 27-MARCH 3)
This will be a colder than average period and we’ll also be vulnerable for potential unsettled weather. Trend for the first potential is for a minor system with snow showers around February 27. Pattern will be “loaded for Lion” for the entry of the month of March, but not sure yet if the lion will just growl (a couple systems that never get together and leave us in between) or launch an all-out attack (systems combine into a larger storm to impact the region).

DAYS 11-15 (MARCH 4-8)
We remain vulnerable to both cold and storminess during this period, but far too soon to see anything in detail.

7:35AM

DAYS 1-5 (FEBRUARY 21-25)
The latest storm system has behaved generally as expected, after being a little slow to get underway as there was a lot of dry air to overcome. But now the warm air has come in aloft with the cold hanging on at the surface, causing snow to turn to sleet and freezing rain. But the steady precipitation is gone and leaving in its wake just patchy drizzle and freezing drizzle, an overcast and areas of fog. But during the course of the day today, low pressure will get northeast of the region and a drying westerly wind will take over, clearing it out and warming it up somewhat. This is not the entrance of a warm air mass, just air warmer than the cold trapped at the ground now. It’ll end up seasonably chilly tonight and Friday as high pressure moves in. This high will retreat Saturday and open the door for the next storm system, a familiar Great Lakes Cutter, on Sunday, which may start as snow/mix briefly Saturday night in some areas with lingering cold, but will end up rain for all as milder air wins out at all levels. Behind this system, drier and colder air will return but the wind may be the bigger story for Monday as the storm will be quite large in eastern Canada as it departs and we’ll have a strong gradient against approaching high pressure from the west.
Forecast details…
TODAY: Overcast with areas of fog and patchy drizzle and freezing drizzle to start, then clearing. Highs 45-52 occurring late in the day. Wind light variable early, then W increasing to 10-20 MPH.
TONIGHT: Mostly clear evening. Partly cloudy overnight. Lows 23-30. Wind W 5-15 MPH.
FRIDAY: Mostly sunny. Highs 36-43. Wind NW 5-15 MPH, diminishing late.
FRIDAY NIGHT: Mostly clear. Lows 18-25. Wind light variable.
SATURDAY: Sun followed by clouds. Chance of rain by late night, may start as snow some areas. Highs 37-44. Wind light variable.
SUNDAY: Cloudy with rain likely, tapering to rain showers later. Temperatures steady in the 40s daytime, falling to the 30s evening.
MONDAY: Sun/clouds. Windy. Lows from the upper 20s to lower 30s. Highs from the upper 30s to lower 40s.

DAYS 6-10 (FEBRUARY 26-MARCH 2)
Dry and cold February 26. Will watch the period February 27-March 2 for the potential of 2 storm systems impacting the region. Too early for details but the first is likely to be minor and include rain and/or snow showers. The second has the potential to be a more significant system with rain/ice/snow possible.

DAYS 11-15 (MARCH 3-7)
Similar pattern, will watch for one or 2 possible storm threats. Also have to watch some very cold air to the north for a possible southward push.

7:12AM

DAYS 1-5 (FEBRUARY 20-24)
This 5-day period will feature the passage of 2 storm systems, the first of which being in a cold enough environment so about half the precipitation, on average, could fall in the frozen or freezing form, starting as snow, going over to sleet and freezing rain, and ending as rain, but for some interior locations that change to plain rain may be hard to complete due to colder air locked in at the surface. This particular storm system will feature a somewhat weaker primary low and slightly more pronounced secondary low tracking near or just south of SNE allowing colder air to stay a little more locked in, but this is still going to be a fairly benign system overall with no major impact from either snow accumulation or icing, beyond the usual slick travel on untreated surfaces. We may see a little more of an issue due to high tides along the coast even with a modest onshore wind during the first half of the storm on east-facing shores, and in Cape Cod Bay Thursday as winds will have turned to westerly, due to the astronomical high tides with the moon just passed full and at perigee. Beyond this, a dry day for Friday as high pressure moves in and dry weather through most of Saturday as high pressure starts to retreat. Next storm system tracks west of New England and results in milder air being more easily able to move in, so it may start as a mix late Saturday night then turn into a rain event for the bulk of Sunday. Drier air may start to work in toward the end of the day on Sunday if the storm system is moving along quickly enough.
Forecast details…
TODAY: Increasing clouds. Highs 28-35. Wind NE up to 10 MPH.
TONIGHT: Cloudy. Snow arriving southwest to northeast, accumulating up to 1 inch south of I-90 and 1-2 inches to the north before changing to sleet and freezing rain. Lows 23-30. Wind NE to E 5-15 MPH.
THURSDAY: Overcast morning with freezing rain and rain ending. Icy untreated surfaces. Areas of fog. Breaking clouds afternoon. Highs 35-42. Wind E to N 5-15 MPH early, NW 10-20 MPH later.
THURSDAY NIGHT: Partly cloudy. Icy untreated surfaces. Lows 20-27. Wind NW 10-20 MPH, higher gusts.
FRIDAY: Partly sunny. Highs 35-42. Wind NW 5-15 MPH, diminishing.
SATURDAY: Partly cloudy. Mix to rain late at night. Lows in the 20s. Highs in the 30s.
SUNDAY: Overcast with rain likely, ending late. Temperatures rise into the 40s through the day and fall back to the 30s at night.

DAYS 6-10 (FEBRUARY 25-MARCH 1)
Colder/dry early next week with windy conditions February 25 and more tranquil February 26. Watching the period February 27-28 for possible unsettled weather (rain/mix/snow) but no solid indications of a major storm. Fair weather follows for the end of this period which is also the beginning of March.

DAYS 11-15 (MARCH 2-6)
Will watch the March 2-3 period of a potential storm threat. Another may threaten late in the period. Temperatures near to below normal.

7:30AM

DAYS 1-5 (FEBRUARY 19-23)
High pressure brings cold and dry weather today between yesterday’s unsettled weather and the next bout of precipitation, which will be arriving Wednesday evening in the form of snow as low pressure moves into the Great Lakes, but this time the primary storm being weaker, a slightly stronger secondary development, and a little colder air will result in a little longer frozen precipitation episode, and while we still warm aloft enough to end the snow-making up there, the surface will stay cold enough for a little more sleet and freezing rain before it finally warms enough at least southern and eastern areas to end as rain Thursday. Thankfully, however, this will not be a prolific precipitation producer or we’d be talking about higher snow totals and more serious icing than we will be seeing. Once this system departs later Thursday, dry weather is back for the end of the week and the start of the weekend, although by Saturday night we may be seeing impacts from the next system, and that may also start as snow.
Forecast details…
TODAY: Mostly sunny. Highs 25-32. Wind NW 5-15 MPH.
TONIGHT: Clear. Lows 8-15. Wind N up to 10 MPH.
WEDNESDAY: Increasing clouds. Highs 28-35. Wind NE up to 10 MPH.
WEDNESDAY NIGHT: Cloudy. Snow arriving southwest to northeast, accumulating up to 1 inch south of I-90 and over inch to the north before changing to sleet and freezing rain. Lows 23-30. Wind NE to E 5-15 MPH.
THURSDAY: Overcast morning with freezing rain and rain ending. Icy untreated surfaces. Areas of fog. Breaking clouds afternoon. Highs 35-42. Wind E to N 5-15 MPH early, NW 10-20 MPH later.
FRIDAY: Partly sunny. Lows in the 20s. Highs from the middle 30s to lower 40s.
SATURDAY: Partly cloudy. Chance of snow at night. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (FEBRUARY 24-28)
Leaning toward a milder solution with snow/mix to rain for February 24 system but have to watch it because this system may end up further southeast and colder. Clearing, windy, colder February 25. Tranquil but cold February 26. Next storm system threatens later February 27 or 28 with some precipitation but does not look major at this point.

DAYS 11-15 (MARCH 1-5)
Early indications are that March may enter like the proverbial lion with some drastic temperature changes and at least one storm threat. Plenty of time to figure out details.

2:35AM

DAYS 1-5 (FEBRUARY 18-22)
Storm #1 departs today but takes a little longer than I previously thought as an elongated trough that was once the primary low makes its way southeastward across the region. So, snow is largely done accumulating by dawn but there will still be some snow showers to go through. After a nice delivery of cold air tonight and a dry, chilly Tuesday courtesy high pressure, storm #2 will head this way and bring the chance of snow by Wednesday night which will likely change to a mix then rain during the course of Thursday morning before ending. This will not be a major storm. By the end of the week, it’s back to dry weather again.

DAYS 6-10 (FEBRUARY 23-27)
Dry start to the weekend February 23 then a storm of mix to rain expected February 24. Dry and colder weather expected February 25-26 then the next storm system may impact the region with rain or snow by February 27. Temperatures near to slightly above normal.

DAYS 11-15 (FEBRUARY 28-MARCH 4)
Mild and unsettled start to the period as February ends. Much colder but dry weather is possible to start off the month of March.

7:39AM

DAYS 1-5 (FEBRUARY 17-21)
Still looking at impact from 2 low pressure systems during this 5-day period, the first a moisture-starved, fast-moving system with enough cold air in place for snow but not enough moisture for very much snow, with the most likely place for a few inches toward the South Coast. This will take place from late tonight into Monday. The second system will have a little more moisture to work with and will have enough cold air around to start as snow, but may not keep enough cold air around to stay snow, taking place late Wednesday into Thursday.
Forecast details…
TODAY: Sunshine followed by increasing clouds. Highs 35-42. Wind light variable.
TONIGHT: Cloudy. Light snow arriving west to east late evening and overnight. Lows 22-29. Wind light variable.
MONDAY (PRESIDENTS DAY): Cloudy start with light snow ending west to east by midday after accumulating a coating to 1 inch except 1-3 inches along the South Coast. Breaking clouds, partial sun, and a few lingering snow showers in the afternoon. Highs 33-40. Wind NW up to 10 MPH.
MONDAY NIGHT: Clearing. Lows 13-20. Wind NW 5-15 MPH.
TUESDAY: Sunny. Highs 33-40. Wind NW 5-15 MPH.
WEDNESDAY: Increasing clouds. Chance of snow late. Lows in the 10s. Highs in the 30s.
THURSDAY: Cloudy with snow/mix/rain, followed by breaking clouds. Lows in the 20s. Highs in the 40s.

DAYS 6-10 (FEBRUARY 22-26)
Dry weather at the start and end of this period. A storm threat mid period (about February 24) at this point looks like a mix to rain event. Temperatures averaging near to slightly above normal overall.

DAYS 11-15 (FEBRUARY 27-MARCH 3)
Will watch for unsettled weather threats about February 28 and March 2 or 3 in a somewhat active but not overly wet pattern as weather systems continue to move rapidly along. Temperatures near to slightly below normal.

9:09AM

DAYS 1-5 (FEBRUARY 16-20)
2 threats of unsettled weather exist during this 5-day period, as the first of what would be 3 remains far to the south to start the weekend. The first actual impact threat to SNE, a small area of low pressure, passes south of the region Sunday night and early Monday but with the bulk of the moisture staying just to the south and a lot of dry air in place, and factoring in guidance over-forecasting precipitation, will go for very light snowfall amounts. A break behind it before a slightly larger and slightly more moisture-laden system approaches by later Wednesday and with enough cold air in place to begin as snow.
Forecast details…
TODAY: Sunny. Highs 37-44. Wind W up to 10 MPH.
TONIGHT: Clear. Lows 17-24. Wind N under 10 MPH.
SUNDAY: Increasing clouds. Highs 35-42. Wind light variable.
SUNDAY NIGHT: Cloudy. Light snow arriving. Lows 22-29. Wind light variable.
MONDAY (PRESIDENTS DAY): Cloudy start with light snow ending west to east by midday after accumulating a coating to 1 inch along the South Coast except up to 2 inches on Nantucket and a dusting to a coating everywhere else. Clearing afternoon. Highs 33-40. Wind NW up to 10 MPH.
TUESDAY: Sunny. Lows in the 10s. Highs in the 30s.
WEDNESDAY: Increasing clouds. Chance of snow late. Lows in the 10s. Highs in the 30s.

DAYS 6-10 (FEBRUARY 21-25)
Snow/mix/rain likely February 21 as a storm passes near or just south of the region (track and precipitation type still somewhat uncertain). Next storm threat about February 24 may drag milder air in with it and be a mix to rain set-up but still quite far out there and low confidence. Dry weather between systems and to end the period as well. Temperatures averaging near to slightly above normal overall.

DAYS 11-15 (FEBRUARY 26-MARCH 2)
Next storm threat in a stubborn pattern would be right around February 28 with another possibly to follow around the end of the period.

7:15AM

DAYS 1-5 (FEBRUARY 15-19)
A warm front / cold front combo comes through the region today (this morning and evening, respectively) as their parent low travels across southern Canada. This system will bring some scattered rain with its warm front, a few isolated rain showers in its warm sector, which will also be filled with a fair amount of wind, and a broken band of showers, which may be weakening as it moves east, along its cold front. Behind this comes colder air for the weekend and during this time a wave of low pressure will miss our area to the south. Still watching a second area of low pressure which gets closer later Sunday to early Monday but still to me looks like it will be far enough for a miss. It would also be fighting some drier air in place even if it was closer, so a “hit” would likely be very minor anyway. Will keep watching. High pressure brings dry weather to end this period.
Forecast details…
TODAY: Mostly cloudy. Scattered light rain morning. Isolated rain showers afternoon. Highs 45-52. Wind SE to S 10-20 MPH, gusts 25-35 MPH.
TONIGHT: Mostly cloudy. A rain shower possible early. Lows 28-35. Wind W 10-20 MPH, higher gusts.
SATURDAY: Partly sunny. Highs 36-43. Wind N 5-15 MPH.
SATURDAY NIGHT: Partly cloudy. Lows 20-27. Wind light W.
SUNDAY: Partly sunny. Highs in the 33-40. Wind light variable.
MONDAY (PRESIDENTS DAY): Mostly cloudy to partly sunny. Lows in the 20s. Highs in the 30s.
TUESDAY: Mostly sunny. Lows in the 10s. Highs in the 30s.

DAYS 6-10 (FEBRUARY 20-24)
Possible snow/mix late February 20 to early February 21 depending on the track of a storm passing near or south of the region. Another low pressure system may impact the region with a risk of rain/mix/snow later in the period. Temperatures near to slightly above normal.

DAYS 11-15 (FEBRUARY 25-MARCH 1)
A system may bring a rain/snow risk around February 27-28 otherwise generally dry weather overall with temperatures near to slightly below normal.

7:23AM

DAYS 1-5 (FEBRUARY 14-18)
As you step outside this morning, beware of some icy patches, which in some areas may be covered by a fresh coating to 1 inch of snow due to some snow squalls last evening, which were certainly a little more potent than I expected them to be as they came across the region. But these slick spots will largely vanish today as we have at least some sunshine and temperatures head to several degrees above freezing, courtesy high pressure which will be in control. Our next foul weather system is not going to be much of a big deal, but will be as low pressure travels across southern Canada, bringing it’s warm front / cold front combo across our area during the course of Friday. This sets up a colder weekend, extended to 3 days for many as Monday is Presidents Day. During the course of this weekend we will see 2 low pressure areas pass south of the region. The first should be a clean miss during Saturday. The second may be close enough for at least the threat of a period of light snow around early Monday, but no guarantee at this point.
Forecast details…
TODAY: Partly sunny. Highs 37-44. Wind W 5-15 MPH.
TONIGHT: Increasing clouds. Lows 25-32. Wind light variable.
FRIDAY: Mostly cloudy. Brief mix possible favoring areas north and west of Boston morning. Rain showers possible west to east late-day. Highs 45-52. Wind light SE early, then SW 5-15 MPH.
FRIDAY NIGHT: Mostly cloudy. A rain shower possible early. Lows 28-35. Wind W 10-20 MPH, higher gusts.
SATURDAY: Partly sunny. Highs 36-43. Wind W 5-15 MPH.
SUNDAY: Partly sunny. Lows in the 20s. Highs in the 30s.
MONDAY (PRESIDENTS DAY): Mostly cloudy to partly sunny. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (FEBRUARY 19-23)
Dry February 19. Another passing wave of low pressure to the south may be close enough to bring a snow/mix threat February 20 followed by clearing February 21. Right now leaning to dry weather for the remainder of the period with temperatures near to slightly above normal.

DAYS 11-15 (FEBRUARY 24-28)
Our short month of February comes down its home stretch with a pattern that this far in advance looks dry and seasonably chilly with a subtropical jet stream suppressed to the south and a fairly dry polar jet stream nearby.
