Monday Forecast

11:25AM

DAYS 1-5 (MARCH 20-24)
The Vernal Equinox occurred at 6:29AM EDT this morning at the precise moment my heart went into atrial fibrillation from a condition I’ve had for years, so because of that, this update is late and abbreviated. I’m on my way to the doctor for an EKG in a few moments. All will be well soon! That’s a high confidence forecast! As for the weather, dry and milder weather takes over today and Tuesday but comes to an end quickly as an arctic cold front plunges out of Canada Tuesday night and early Wednesday and sends us into the March freeze zone again. Winds diminish by Thursday as high pressure builds in though it will still be a chilly day, then it moderates somewhat but with clouds arriving on Friday ahead of a warm front.
TODAY: Mostly sunny. Highs 37-44. Wind N 10-20 MPH with higher gusts.
TONIGHT: Clear. Lows 20-27. Wind NW 5-15 MPH with higher gusts.
TUESDAY: Mostly sunny. Highs 45-53. Wind W 5-15 MPH with higher gusts.
WEDNESDAY: Partly cloudy. Windy. Lows 15-22. Highs 28-35.
THURSDAY: Mostly sunny. Lows 5-15. Highs 32-40.
FRIDAY: Mostly cloudy. Lows 20-27. Highs 40-47.

DAYS 6-10 (MARCH 25-29)
Saturday March 25 is a low confidence forecast and is dependent on whether or not a warm front makes it partially or fully through the region as expect at least some cloudiness and coolest temps north (40s), and milder south (50s), but add 10 degrees to this if the front makes it through. Front comes back as high pressure builds across eastern Canada by Sunday and it turns colder again. Wildcard is if we get a brief shot of rain/mix as the temps drop, or if precipitation lingers later Sunday into Monday and includes more snow and ice. Will fine-tune this as we get closer. Fair and chilly weather to end the period seems a good bet.

DAYS 11-15 (MARCH 30-APRIL 3)
Another episode of unsettled weather is most likely during the early to middle of this period. Temperatures variable, mainly below normal.

Sunday Forecast

8:20AM

DAYS 1-5 (MARCH 19-23)
Redeveloping low pressure south of New England today will move northeastward into the waters east of New England through early Monday with the aforementioned snow threat confined mainly to Cape Cod (starting as rain in some areas) but a few snow showers coming off the ocean into eastern MA through this evening with the aid of maritime moisture and an weak trough of low pressure. This may linger into early Monday but as we enter the first hours of spring (Vernal Equinox in the morning) we’ll see sunshine take over as it turns a little milder. Slightly warmer still on Tuesday for the first full day of spring but a quick return to the feel of winter follows this on Wednesday as an arctic cold front dives southward through the region. This chill-down will bite hardest with wind Wednesday but last into Thursday as well, albeit with much less wind by then.
TODAY AND TONIGHT: Cloudy. Periods of rain and snow Cape Cod, becoming mainly snow, with accumulation of 1 to 3 inches possible there. Scattered to isolated snow showers NH Seacoast and eastern MA to RI with a few dustings possible. Highs 30-37. Lows 22-30. Wind NE 10-20 MPH with higher gusts inland, 20-30 MPH with higher gusts coast, including some 40-50 MPH gusts Cape Cod.
MONDAY: Mostly cloudy with bit of light rain/snow possible eastern MA / NH Seacoast early, otherwise clearing. Highs 37-44. Wind N 10-20 MPH with higher gusts.
MONDAY NIGHT: Clear. Lows 20-27. Wind NW 5-15 MPH with higher gusts.
TUESDAY: Mostly sunny. Highs 45-53. Wind W 5-15 MPH with higher gusts.
WEDNESDAY: Partly cloudy. Windy. Lows 15-22. Highs 28-35.
THURSDAY: Mostly sunny. Lows 5-15. Highs 32-40.

DAYS 6-10 (MARCH 24-28)
A transition from chilly to warmer weather tries to take place March 24-25 but may be met with some difficulty – will watch how this evolves. Transition back to cold may include rain/ice/snow March 26. Fair and chilly to end the period.

DAYS 11-15 (MARCH 29-APRIL 2)
Another episode of unsettled weather is most likely during the early to middle of this period. Temperatures variable in typical early spring fashion.

Saturday Forecast

9:18AM

DAYS 1-5 (MARCH 18-22)
High pressure tries to hang on today as a low pressure area dives southeastward from the Great Lakes toward the Mid Atlantic Coast. This initial low will send some cloudiness into the region later today and perhaps some areas of very light to light snow tonight. The low will redevelop south and southeast of New England Sunday then take its time departing through Monday. This will bring a threat of snow and rain to eastern MA and RI Sunday and Sunday night with some lingering drops and flakes into Monday over eastern areas. Monday is the occurrence of the Vernal Equinox, or in more simple terms, the first day of spring. But we’ll have to wait until Tuesday to have a day that feels a little more like spring. But in typical New England fashion, that will be a tease, as an arctic air mass plunges out of Canada and arrives here on Wednesday.
TODAY: Sunshine fading behind increasing clouds. Highs 33-40. Wind light variable.
TONIGHT: Cloudy. A few periods of very light to light snow with only a few dustings possible.. Lows 20-27. Wind light N to NE.
SUNDAY AND SUNDAY NIGHT: Cloudy. Periods of rain and snow, becoming mainly snow, especially RI and eastern MA, with some accumulation of up to 1 or 2 inches except locally heavier, with most accumulation occurring on unpaved surfaces and during the evening hours. Highs 30-37. Lows 22-30. Wind light NE to N early then increasing to 10-20 MPH except 20-30 MPH with higher gusts Cape Cod area.
MONDAY: Mostly cloudy. A bit of light rain/snow possible eastern areas early. Highs 37-44.
TUESDAY: Mostly sunny. Lows 20-27. Highs 45-53.
WEDNESDAY: Partly cloudy. Windy. Lows 15-22. Highs 28-35.

DAYS 6-10 (MARCH 23-27)
Dry and cold to start then a warm-up follows. A flip to colder late in the period will probably be preceded by rain then mix/snow for parts of the region.

DAYS 11-15 (MARCH 28-APRIL 1)
Another episode of unsettled weather is most likely during the early to middle of this period. Temperatures moderate then cool again.

7:34AM

DAYS 1-5 (MARCH 17-21)
Hello and Happy St. Patrick’s Day to all! Apologizes for the post that left you a bit info-deprived yesterday. Back on track today! High pressure provides what will be the nicest day of the week today, albeit starting with some cloudiness over parts of eastern MA due to a weak inversion (a thin layer of warmer air just above colder air) in the lower atmosphere this morning. Low pressure will approach Saturday and wobble its way south of New England Sunday, intensifying as it does so. An area of mix/snow will occur Saturday night into Sunday for at least portions of southern New England (CT, RI, southern MA) and the questions remain of how heavy does it get and how far north and west does it expand. Will attempt to answer these by tomorrow, but for now the further south and east you are the better chance of accumulating snow exists. There may be a fairly narrow swath of significant snow along an inverted trough (basically a line of lower pressure and air convergence that extends back from a departing low pressure center). Spring arrives, well the Vernal Equinox occurs, on Monday, and some nicer weather is expected then as well as Tuesday. But we know that the arrival of official spring does not always mean the winter switch is shut off…
TODAY: Variably cloudy start over eastern MA then increasing sun. A few clouds may drift into RI. Mostly sunny otherwise. Highs 35-42. Wind light variable.
TONIGHT: Mostly clear. Lows 10-15 interior snow-covered areas, 16-22 elsewhere. Wind light variable.
SATURDAY: Sunshine fading behind increasing clouds. Highs 33-40. Wind light variable.
SATURDAY NIGHT: Cloudy. Snow developing overnight especially southern MA, CT, RI. Lows 20-27. Wind light N to NE.
SUNDAY: Cloudy. Periods of snow, especially southern areas, with some accumulation. Highs 30-37. Wind light NE to N.
MONDAY: Partly cloudy. Lows 15-22. Highs 40-47.
TUESDAY: Mostly sunny. Lows 20-27. Highs 45-53.

DAYS 6-10 (MARCH 22-26)
Unsettled weather is possible both early and again late in the period. Temperatures near to below normal.

DAYS 11-15 (MARCH 27-31)
Another episode of unsettled weather is most likely during the middle of the period. Temperatures near to above normal.

Wednesday Forecast

7:40AM

DAYS 1-5 (MARCH 15-19)
Beware of very icy surfaces today! Many of these will not melt off if they are not in direct sun for at least 2 hours, or treated thoroughly. The feel of mid winter continues as the cold pattern goes on. A few snow showers are possible today as an upper level low pressure area swings through the region. It will still be close enough on Thursday to create some additional cloudiness. By Friday, high pressure will bring dry, bright weather for St. Patrick’s Day. A broad low pressure trough is expected to cross the Northeast this weekend and bring the next round of unsettled weather to southern New England with mix/snow possible. Not quite sure how this plays out yet.
TODAY: Sun to start, then clouds and scattered snow showers this afternoon. Highs 28-35. Wind W 15-25 MPH, higher gusts.
TONIGHT: Mostly to partly cloudy. Chance of snow showers early. Lows 18-25. Wind W 10-20 MPH, higher gusts.
THURSDAY: Partly sunny to mostly cloudy. Highs 30-38. Wind W 10-20 MPH, higher gusts.

Tuesday Forecast

7:47AM

DAY 1 (TODAY)
Storm day. Here is what to expect. Low pressure tracks northeastward and rapidly intensifies today. The center of low pressure will cut across southeastern MA this evening then track across the Gulf of Maine and into eastern Maine during tonight. Breaking down the details:
Precipitation… Areas of snow develop between 4AM and 6AM CT and RI, and between 5AM and 7AM MA and southern NH. Snow increases in intensity and falls at the rate of 1 to 4 inches per hour from late morning into afternoon, but a snow to sleet to rain line will enter Cape Cod and the South Coast by midday then eventually work north northwestward into southeastern MA and eventually to Cape Ann MA to Boston and down the I-95 corridor to Providence RI while snow continues to the northwest and west, then this changeover line will hold in place for a short time as the low pressure area cuts across southeastern MA, then will pull east again at night. Heaviest rain will occur over Cape Cod and far southeastern MA but as it works northwestward a slot of drier air will move up from the south and diminish if not stop the precipitation in RI, eastern MA, and southeastern NH early evening before some snow pulls eastward across northern and central MA and southeastern NH later at night.
Snow accumulation… 1-3 inches outer Cape Cod and Nantucket before rain, 3-6 inches remainder of Cape Cod before rain, 6-12 inches Cape Ann to Boston and down the I-95 corridor to southern and eastern RI and across southern CT before mix/change which may include a period of sleet for some areas, 12-18 inches northwestern RI, central and northern CT, the remainder of MA and southern NH, and areas of greater than 18 inches outside of I-495 especially in central MA, southwestern NH, and areas of western MA as well.
Wind… North to northeast over interior areas, northeast to east in coastal areas in advance of the low pressure area increasing to 25-35 MPH inland and 35-45 MPH coastal areas but gusts above 50 MPH are likely at times interior areas and above 60 MPH near the coast, including some gusts over 70 MPH on parts of Cape Cod. As low pressure crosses southeastern MA along its path the winds will drop off to variable and under 20 MPH near its path, remain northeast to north and still quite strong to its northwest and shift to south and southwest 20-40 MPH and gusty to the southeast of the track. Once the low is offshore, winds will be north to northwest 15-35 MPH with higher gusts all areas.
Coastal Flooding… Minor to moderate coastal flooding at high tide times favoring east-facing and north-facing coastal areas a couple hours either side of this afternoon’s 1:25PM high tide, and favoring north-facing and west-facing coastal areas (Cape Cod Bay) during the near 2AM high tide Wednesday morning.
Damage / Power Outages… Many weakened trees from drought and recent wind events could lose branches or fall. Power outages are most likely in southeastern MA but could occur anywhere.
Temperatures… Late day high temps reach 25-30 southwestern NH and central MA, 30s elsewhere except 40s along and southeast of where the low pressure center tracks, with a 50 possible on Nantucket. Temps tonight fall back to the 20s in all areas from northwest to southeast so areas that saw wetter snow and a change to rain will experience a freeze-up.

DAYS 2-5 (MARCH 15-18)
Upper level low pressure crosses the region Wednesday, then high pressure takes control Thursday and Friday. Next storm threat arrives this weekend but will re-evaluate that for the next update.
WEDNESDAY: Variably cloudy. Chance of snow showers. Highs 30-38. Wind NW 10-20 MPH.
THURSDAY: Partly cloudy. Lows 13-20. Highs 32-40.
FRIDAY: Mostly sunny. Lows 13-20. Highs 35-43.
SATURDAY: Increasing clouds. Chance of snow/mix late. Lows 15-22. Highs 35-43.

DAYS 6-10 (MARCH 19-23)
Snow/mix possible early March 19 and another risk of unsettled weather the middle of the period. Temperatures below normal.

DAYS 11-15 (MARCH 24-28)
Additional unsettled weather most likely the middle of this period. Temperatures below normal.
