DAYS 1-5 (MARCH 20-24)

Spring arrived last night (11:06 p.m. vernal equinox) and these early spring days will present us with plenty of weather to keep track of. Today, a disturbance moves through the region in the form of an initially weak low pressure area, pushing a warm front with a few rain showers through this morning. We’ll get a break for several hours where it’s pleasantly milder and less windy than yesterday, and then a strong cold front will come along this evening with more potent showers of mostly rain, though with an immediate arrival of cold air, some of these can mix with and change to snow, especially north of I-90, before they wind down later at night. This will take place as the initially weak low redevelops and intensifies rapidly as it enters the Gulf of Maine (giving parts of Maine a quick-hitting snowstorm tonight). Behind this system, we’ll have a chilly, windy Thursday but with dry weather. Quick-moving systems mean that we’ll see clouds increasing ahead of our next storm system during Friday. This system’s center looks as if it will be far enough north so that cold air that allows the precipitation to start mixed or as snow for some of the region should be pushed out enough for the heaviest of it to fall as rain in much of the region Friday night into Saturday. Two uncertainties: A slight southward shift in that storm track would mean more frozen precipitation could be involved, so we need to watch that closely, and also the timing of the departure, which may end up somewhat delayed by a slower-departing system. Sunday looks like a dry, breezy, chilly day, but we’ll have to watch southeastern areas for a blanket of clouds that may hang on behind the weekend system, though at this point I think precipitation would remain offshore.

TODAY: Cloudy start with scattered rain showers. Some breaks of sun later morning into afternoon before a cloudier finish and another rain chance especially west and north of Boston. Highs 47-54. Wind variable up to 10 MPH, then SW 5-15 MPH, higher gusts late in the day.

TONIGHT: Cloudy evening with rain showers likely, even a slight chance of a thunderstorm. Rain showers may mix with or turn to snow showers west to east, especially north of I-90, before ending. Clearing overnight. Lows 28-35. Wind SW 10-20 MPH with higher gusts, shifting to NW. Black ice patches possible.

THURSDAY: Sun and passing clouds. Highs 37-44. Wind NW 10-20 MPH, gusts 25-35 MPH.

THURSDAY NIGHT: Partly cloudy evening. Clear overnight. Lows 25-32. Wind NW 10-20 MPH, diminishing overnight.

FRIDAY: Sun followed by clouds. Highs 38-45. Wind W 5-15 MPH becoming variable up to 10 MPH.

FRIDAY NIGHT: Cloudy. Snow/mix north, mix/rain south. Lows 28-35 evening, may rise overnight. Wind NE to E 5-15 MPH, stronger at the coast.

SATURDAY: Overcast. Rain likely, may be mixed with sleet and/or snow north at least early in the day. Highs 36-43. Wind E-NE 10-20 MPH.

SATURDAY NIGHT: Cloudy. Chance of rain, possibly mixed with sleet/snow. Lows 33-40. Wind NE-N 5-15 MPH.

SUNDAY: Clouds linger southeastern and eastern areas, clearing northwest. Highs 40-47. Wind N 5-15 MPH, higher gusts.

DAYS 6-10 (MARCH 25-29)

Dry to start, then additional unsettled weather with rain/mix/snow opportunities. Temperatures variable for the period, averaging somewhat close to normal.

DAYS 11-15 (MARCH 30 – APRIL 3)

Additional unsettled weather threats and variable temperatures in an active early spring weather pattern.

  1. Thank you, TK. Am I first? This will be the only time I hope. I will ask for a later time for my second eye

    Happy birthday, Dr S?

  2. Good morning and thank you TK.

    Only made it to about 47 here yesterday.

    Overnight down to 36 and now back up to 40.

    HAPPY SPRING!!!!

  5. Flakes in the air this morning…only took the calendar flipping to Spring to make it happen! 2024-2025 Winter will be our year

  7. If I had to hazard a guess Mt. Washington could see the strongest winds thus far this year in the coming 36 hours (wouldn’t be surprised if gusts of over 100mph are registered). March and April are notoriously windy atop the rock pile, but this particular front will usher in especially strong winds and a fresh blanket of snow.

    1. Thanks. Afraid son in law may have to postpone. Glad guide is there to be an experienced voice in the group.

  8. Thanks, TK!

    Philip, I was listening to forecaster Rob Carolan this morning on Fall River station WSAR and he was talking about the April 8 eclipse. He said that, in northern New England, that totality will last 2-3 minutes at around 3:30. I think that was the question you had asked last night.

    Last night I wrote that Middleborough will have 91.6% totality. What I meant to say was 91.6% darkness.

  9. Thanks, TK.

    Volcanoes in Iceland; several earthquakes in Texas. Similar things happening around the world. Climate change? I just can’t see how those things would be due to climate change. Earth change? Hey, I could be wrong. Anyway, Happy Spring. Kind of sunny/cloudy here.

  10. Another woman here is from marshfield. She saw Humarock on my bag. So I have someone fun to talk to.

    1. Some one on the blog? I wonder how many “lurkers” there are here????? I’d be curious to know that. 🙂

        1. Cool. Should I tone down my comments???
          Mostly, I think mine are fine, but occasionally I can get a little edgy/snarky

          Hope I have not offended anyone well known.

  11. All that talk of snow in June had me thinking, the coldest I’ve ever experienced in June was in 2015. It didn’t get above 49F on both June 1st and 2nd.

    1. It was 48 with off and on cold showers with blustery breezes at our school’s outdoor graduation last June 3.

  12. I’m rooting for more snow! We’ll see if my neck of the woods gets any measurable snow this weekend. I recently fixed the snow blower and need to test it 🙂

          1. I looked at a home for sale once on that street. Nice home despite a big hole in the middle of their high porch! I’m about 5 miles from there on opposite side of town.

    6-8 pm in eastern Mass could be interesting this evening.

    I see TK included thunder in his forecast. The lapse rates are pretty good. I think we have too much boundary layer warmth to overcome in Boston and southeastward to flip briefly to snow.

    Something is up for interior Maine. Small meso low intensifying may cause a few hrs of heavy snow near and certainly northwest of I-95 in central translating towards eastern Maine.

  17. The AI ECMWF forecasts over 160 inches of snow for parts of Maine over the next 48 hours….

    Yeah, and I’m MRS. CLAUS!

  18. Another body found in the Charles River, usually under one of the main bridges (BU, Mass. Ave, Longfellow). Very sad.

    This happens way too often. And it’s almost always at a point along my run which is parallel to the Charles River.

    “Police are investigating after a body was pulled from the Charles River near the Massachusetts Avenue bridge Tuesday, officials said.

    The State Police Marine Unit and Dive Team recovered a body that was seen east of the bridge in the Charles on Tuesday, a police spokesperson told Boston.com.”

  21. Very high based rain producers. Dew point depression at Boston is 28 degrees! That’s impressive.

  24. TK, I also was a cross-dresser once and it was Halloween, either 1998 or 1999. I dressed up as Miss Pumpkin and took my then small children around the neighborhood. They loved the idea and were also a bit reluctant to introduce their `father’ to the neighbors. I had to stay pretty far away from the front doors of people’s houses. When asked, “where are your parents?” my son Daniel would say (using language that is now considered 100% correct) “they’re over there,” pointing vaguely in my direction as I was on the sidewalk. Their mother didn’t join us. She was too embarrassed, though she liked the idea.

    Wearing my sister’s orange skirt, I got VERY cold that night. As I said it was either 1998 or 1999, whichever Halloween night was quite cold, as in low to mid 30s as I recall. And I caught a cold.

    1. Ugh on the cold. But I hope you had fun at least! I’m going to find that pic of me.

  25. Thanks TK!

    This is always such an interesting time of year for weather in New England. The “spring vs winter” atmospheric battle can lead to some very energetic results, like today’s system.

    We are finally getting some decently warm weather here in SoCal, but the Pacific storm door is just about ready to reopen… the Sierra has a longggg way yet to go with snow this season…

  30. 00z NAM (12km) is good for a laugh. It has rain change to heavy snow before ending Sunday morning. How heavy? Widespread 4-8″ in a 3-hour span.

    2. HAHAHAHAHA!!!

      As much as that’s likely supremely out to lunch, I’d love it if it happened.
