DAYS 1-5 (MARCH 12-16)

Our active weather pattern continues with several weather systems to contend with through the start of next week. Today, we’re back in a wedge of warmer air after yesterday’s back-door front pulled a reversal in response to low pressure passing to our north and moved back as a warm front, causing a nocturnal temperature rise overnight, along with showers and even some embedded thunderstorms in some areas. The cold front trailing this low will move across our region today and an additional disturbance will create a wave of low pressure on it to move through the region late today and this evening. This scenario creates additional periods of rain in our region today that will mix with and change to sleet and snow as colder air arrives, enough so that some minor accumulation can occur, especially on unpaved surfaces, by this evening. With the temperature continuing to go down a little bit more even as this system ends and we see clearing later tonight, this will result in some slippery travel on untreated surfaces that remain wet. We get very little break with just some sun early Friday before clouds return ahead of the next low pressure area, this one a smaller system coming eastward from the Great Lakes. The center will pass to our north Friday night and early Saturday, and we get its warm front first, with some rain and snow possible later Friday into Friday evening, especially north of I-90, while its cold front follows with rain and snow showers overnight into early Saturday morning. Improving weather follows during the day Saturday, and with the next system moving into the Great Lakes during Sunday we’ll see clouds once again return as its warm front approaches. This one should have limited moisture, initially, so that only a touch of light precipitation favors areas well northwest of Boston later Sunday. However, things change as that front goes by during Sunday night as a significant influx of subtropical moisture is drawn up the East Coast. Intensifying and larger scale low pressure moving through the Great Lakes into eastern Canada will drag a cold front our way during Monday, with all of the aforementioned moisture flowing northward ahead of it. This means a significant rain event for our area, along with very mild air during the day on Monday. We’ll have to scrutinize this system more as the time draws nearer to pinpoint potential flooding issues and even the chance for some wind damage.

TODAY: Cloudy. Areas of fog this morning. Periods of rain mixing with and changing to sleet and wet snow from west to east later. Highs 48-55 South Coast, 55-62 elsewhere, occurring early to mid morning, followed by a steady temperature fall from west to east to the 30s by mid to late afternoon. Wind W 5-15 MPH with higher gusts, shifting to NW from west to east.

TONIGHT: Cloudy early with sleet to wet snow, accumulating a coating to 1 inch. Partial clearing late. Watch for black ice on untreated surfaces. Lows 28-35. Wind NW 5-15 MPH, diminishing overnight.

FRIDAY: Sun followed by clouds. Late-day mix / snow possible favoring north central MA / southwestern NH. Highs 38-45. Wind variable up to 10 MPH.

FRIDAY NIGHT: Cloudy evening with snow / mix / rain most likely in southern NH and northern MA and a few rain showers to the south. Lows 31-38, coldest southern NH / northern MA. Wind variable 5-15 MPH becoming W with higher gusts overnight.

SATURDAY: Mostly cloudy early with rain and snow showers possible, then a sun / cloud mix. Highs 43-50. Wind W to NW 10-20 MPH, higher gusts.

SATURDAY NIGHT: Partly cloudy. Lows 28-35. Wind NW 5-15 MPH, diminishing.

SUNDAY: Mostly cloudy. Evening mix potential well north and west of Boston. Highs 45-52. Wind variable to SE up to 10 MPH.

SUNDAY NIGHT: Cloudy. Rain showers arrive and become widespread. Temperatures steady early then rising through 50s except remaining steady South Coast. Wind SE to S increasing to 10-20 MPH with higher gusts.

MONDAY: Cloudy with widespread rain showers. Chance of a thunderstorm. Highs 57-64 except 50-57 South Coast. Wind S 15-25 MPH, higher gusts.

DAYS 6-10 (MARCH 17-21)

Fair weather and below normal temperatures behind the storm system March 17-19. Next low pressure system looks more minor and brings a precipitation chance March 20-21 to mark the arrival of spring (equinox occurring at 10:46 a.m. EDT on March 20).

DAYS 11-15 (MARCH 22-26)

The pattern for the early days of spring continues show signs of typical volatility with up and down temps and a couple periods of unsettled weather.

  3. Thanks TK !

    The remaining snow piles have fog rising from them in this mild, humid air.

      1. Welcome to the 5 car!!!
        Looks like a pretty frustrating Wordle today. Amazing how
        it goes that way sometimes. Persistence paid off as you certainly got the word!!!

        I think I would have lost my mind with that kind of result.

        At least I worked up to the 5 solution and wasn’t right there after guess 2.

        WELCOME ABOARD!!!

          1. I figured….
            Sorry. I have a hard time choosing what Wordle wants.
            I am NOT in sync with Wordle. You usually are, just not today.

    1. A general consensus of “around” an inch or so. BOOO
      BUT, it will be gone very quickly, so no matter!!!

  11. Thank you, TK. We are down to 52 from our overnight high of 58.

    0.12 rain yesterday and 0.29 so far today.

  12. Our temperature has gone from 58F to 48F in the past three hours.

    My son looked at the thermometer before leaving for work and said, “Wow – it’s up to 50 already.” I had to break it to him that it’s actually DOWN to 50 already. 🙂

    1. I was up for at 4:15 and it was 56 then. Otherwise, I might have thought the same as your son. Upside down day

    1. In that case you also think mine is underdone. 🙂

      If anyone breaks an inch it’ll be the top of blue hill.

      Positive snow depth change maps apply today.

      2. I guess we’ll find out. 🙂
        I really don’t care. A coating, 1/2 inch, an inch. This time of year, that’s all the same. It’ll be gone in no time at all.

    3. It’s probably overdone, but the idea is based on what happens when we PV-stretch in spring. The extremes can be pretty intense. It’s rather rare to see.

  23. Wordle in 3 today. More interesting I got two in the correct spots with no misplaced in the first AND second then got the word on the third. So no yellow squares!

    How do you print the grid without letters? Do you have to be signed in? I have an account but often don’t bother to sign in. Ty

    1. Awesome work

      If you go to see results and choose share you get a link without letters. Save to images and then use ibb to get a link.

    2. Unfortunately, that’s what happens when you try to paste the results directly into a comment here. The yellow and green squares disappear.

      Great job getting it in 3!

  31. Fairfax VA after yesterday’s high of 87 is currently 35 with moderate snow falling and accumulating. 🙂

    1. Now is the sharpest drop. Next couple hours that rate slows and we’re only good for another ~6 to ~12 more degrees in most locations which will put low temps a few degrees either side of freezing (28-35).

      1. We are still sitting at 36. But maybe I’m close to the low?? It’s been nice not using heat. Or is it $$$$

        Reply

  35. I believe I am seeing some sort of mix in Whitman right now. Car temp shows 39 but we all know it probably isn’t accurate.

    Reply

    1. We had mixed flurries at that temp.

      Enjoy. I always love seeing snow in the air. Just not ready for another “storm”
