DAYS 1-5 (APRIL 29 – MAY 3)

Today’s weather will be quite nice, in most areas, most of the time, but the temperature by day’s end is going to end up varying significantly from one part of the area to another. We had a mild night sitting in the “warm sector” or a warm air mass, and while some clouds trying to move in from the northwest can limit the sun, we’ll still warm up nicely, but this will be thwarted along the coast by a sea breeze by midday, and then systematically wiped out by a back door cold front that arrives from northeast to southwest later today and tonight. Some midday showers can slide across southern NH and nearby northeastern MA. Other than that there’s the potential for a pop up shower over inland areas by evening. With the front sliding far enough southwest, high pressure in eastern Canada and weak low pressure moving along the boundary to our south Tuesday and early Wednesday, we’ll have the opportunity to see some rain at times, though not very much, with most of it Tuesday night, but it will be quite cool with a region-wide onshore flow from the chilly Atlantic. Drier air will result in some improving weather during Wednesday as the low moves away and high pressure exerts a little more influence. There are a few adjustments being made to the forecast in today’s update for later in the week. With that boundary still sitting to our south, stronger high pressure still to the north, and a weak disturbance moving through the region in a northwesterly air flow aloft, Thursday’s forecast is a bit different in comparison to my ideas of just 24 hours ago. It looks cloudier and not as warm. We may even see a few showers around as the warmer air to the south fights to move back in, but doesn’t make it. Not even sure it makes it in on Friday either when at the very least the coast is likely to be much cooler than inland areas as high pressure from Canada noses in with fair weather.

TODAY: Sun/cloud mix. Midday showers southern NH and northeastern MA. A late-day pop-up shower possible west of I-495. Highs ranging from 60-67 coast to 67-74 inland occurring by early afternoon, but falling back to the 50s coastal areas with a sharper temperature contrast heading inland during mid to late afternoon. Wind variable up to 10 MPH with coastal sea breezes developing.

TONIGHT: Partly cloudy with isolated rain showers in the evening. Mostly cloudy overnight. Lows 43-50. Wind shifting to NE 5-15 MPH.

TUESDAY: Cloudy. Highs 50-57, coolest coast. Wind E 5-15 MPH.

TUESDAY NIGHT: Cloudy. Periods of light rain. Areas of drizzle/fog. Lows 44-51. Wind E 5-15 MPH.

WEDNESDAY: Cloudy with lingering light rain/drizzle possible early, then breaking clouds. Highs 53-60, warmest inland. Wind E up to 10 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Lows 45-52. Wind E under 10 MPH.

THURSDAY: Mostly cloudy. A shower possible. Highs 52-59, coolest coast. Wind SE up to 10 MPH.

THURSDAY NIGHT: Mostly cloudy with a possible shower in the evening. Partly cloudy overnight. Lows 45-52. Wind SE to variable up to 10 MPH.

FRIDAY: Partly to mostly sunny. Highs 55-62 coast, 63-70 inland. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (MAY 4-8)

This forecast is not high confidence so check upcoming updates. Currently thinking the May 4-5 weekend starts mild with fair weather, then a front moves through with showers for a portion of May 5. Next system with a shower threat around May 7 otherwise a fairly dry pattern mid to late period.

DAYS 11-15 (MAY 9-13)

Generally dry pattern with a cooling trend with dominant air flow out of eastern Canada.

  3. Good morning and thank you.

    We’re up to 70 ALREADY in JP.
    The wind has NOT turned NE or East yet
    and any cooling from the front that has gone through is obviously lagging behind.

    So, according to the WPC, the front has come through already, but wind is still NW to NNW for now. 🙂

        1. Warming up SUPER fast!!

          up to 73 here already.

          If stayed in the warm sector today, most of us would have cracked 80 for sure. If it doesn’t cool off soon. some may still crack 80. 🙂

  8. Still 70 at the airport with NNW at 12 mph.
    It has dropped back to 71 here.

    Have to go all the way NW to Rutland, VT to really get into the cooler air where it is currently 46, 52 at Bennington and 53 at North Adams, MA.

    1. THERE IT IS!!!!!

      Now down to 59 at the airport with EAST wind at 17 mph!!!!

      That is what I expected to wake up to….

      But it is here now and will be spreading inland.

      Still 71 here, but I fully expect that to start dropping any moment now. 🙂

  13. Down to 57 at Logan. Will it get to the 40s as the NAM
    predicted yesterday? Time will tell. 🙂
    Even if not, still plenty cool enough. Give me yesterday PLEASE!!!!

  14. Down to 63 from 73 here. How low will it go?
    Upper 50s for sure. How much lower is the question. Likely lower than that. Hope not. Upper 50s at this time of year is still
    “comfortably” cool and just a little below average. Lower to mid 50s getting much less comfortable and 40s, FORGET IT!!!!!!!!

    1. The cooler air will eventually make it there, but at least
      you can enjoy one more warm day. 🙂

      Logan is now down to 55!!!!

  21. Logan is now down to 54 and one of the COLDEST locations in all of New England! Go Figure! The Arm pit of New England!!!!!

    Geez, down to 59 here!

        1. As noted in my discussion, that guidance is probably too far north with the warm air for Thursday. It will be “warmer” inland, but the coast is likely to stay rather cool that day, and there may be an abundance of clouds as well.

  28. Was down to 57 here, but the sun came out a bit and we’re back up to 60. I was just walking down the center and it is actually very pleasant out here. 🙂

    1. Nice. Down to 72 here. I was in Quincy at the office earlier in the day and it was neat watching the car thermometer rise that much on the way home around 2.

  34. 63 and overcast when I left school in Middleborough at 2:30.
    73 and totally sunny with deep, blue skies when I arrived in Taunton at 3.
    61 now.

    Celts up 10 at the half.

    1. Nope. At the end of the first quarter. I thought 34 points was too low for a halftime score.

  36. Very belated thanks, TK.

    I ran the a/c in the car for the first time this afternoon shuttling around Westborough and Ashland — it was variously in the high 70’s, and the sun was strong, despite sometimes being slightly filtered.

    1. Most passed north of us but my lightning detector did detect some as close as 5 miles. The temp did drop about 5 degrees after most of it passed by to the north.
