DAYS 1-5 (APRIL 20-24)

High pressure approaches with bright but breezy and cool weather today. High pressure moves overhead with a clear and very chilly night tonight. The high slides offshore and a warm front moves through Thursday, followed by a cold front Thursday night / early Friday as these fronts’ parent low moves eastward passing to the north of New England. This will be basically a dry frontal pair with most shower activity staying to the north as the system will not carry much moisture with it. Once again, while we warm up a little with the warm front, we’ll be briefly even warmer behind the cold front (similar to a recent event) due to the down-slope effect of a westerly wind. Cooler air will arrive Friday night and the upcoming weekend will be a little on the cooler side as well, because high pressure centered to the northwest and north of New England will transport some cooler air in and also allow for onshore winds to develop. By Sunday, we may see more cloudiness and even some late-day rainfall with the approach of a warm front.

TODAY: Sunshine with passing fair-weather clouds. Highs 55-62. Wind WNW 10-20 MPH with higher gusts, diminishing late in the day.

TONIGHT: Mostly clear. Lows 35-42. Wind variable under 10 MPH.

THURSDAY: Partly sunny. Highs 60-67, cooler South Coast. Wind S 5-15 MPH.

THURSDAY NIGHT: Variably cloudy. Slight chance of a brief shower southern NH / northern MA. Lows 48-55. Wind SW 10-20 MPH shifting to W.

FRIDAY: Partly cloudy. Highs 63-70. Wind W 5-15 MPH, higher gusts.

FRIDAY NIGHT: Mostly clear. Lows 45-52.Wind NW up to 10 MPH.

SATURDAY: Sunny to partly cloudy. Highs 57-64, coolest coast. Wind N to variable up to 10 MPH with coastal sea breezes.

SATURDAY NIGHT: Mostly clear. Lows 37-44. Wind variable up to 10 MPH.

SUNDAY: Sun followed by clouds. Chance of light rain late. Highs 57-64. Wind variable to SE up to 10 MPH.

DAYS 6-10 (APRIL 25-29)

Brief warm-up possible April 25. Frontal system and low pressure area brings shower chances April 26. Some atmospheric blocking may result in a stretch of cooler and unsettled weather midday to later part of next week.

DAYS 11-15 (APRIL 30 – MAY 4)

Blocking pattern potential with near to below normal temperatures, near to above normal precipitation at least early part of period. Block may break down later in the period with zonal flow returning.

      1. When I turned off my ad blocker last night, I got a 30-second video ad. I suppose it could be different at different times and for different people. I simply don’t visit sites that disallows ad blockers. Just now as I was testing I saw a gazillion ads in boxes on the weather page. Hey look at that, I am interested in the weather, but, it is my lucky day, because I see an ad for a toenail fungus treatment!

    1. I can’t remember anyone else’s birthday on here but JJ’s is easy because it is the day after mine!

  15. Thanks, TK!

    Happy birthday, JJ and Mark!!! 🙂

    Mrs. Fantastic and I are celebrating our 35th wedding anniversary today! We were wed on Easter Monday/Patriots Day/Marathon Monday, 1987!

  18. Not a whole lot of positive temp anomaly in the USA on the GFS but there sure is quite a bit of negative seen over the next couple weeks on today’s 12z run.

    1. Sharp downward turn in temperature next week – increasing snow chances – across Southern Ontario and Quebec. Further north – Hudson Bay area and Labrador, respectively – it’ll be quite wintry the final week of April and the first week of May. Given this rather extensive pool of cold air, it’s doubtful we in SNE will see a sustained warm-up anytime soon. It’ll come, eventually. But, as is often the case, it’ll take some time. The cold in Canada will retreat for a 3 month break, starting in late May/early June.

    2. Well that speaks well for not having heat. One upside is in the future, we clearly only need heat from mid November at the earliest (Dec 1 if possible) through April 1.

      I recommend everyone try it ‍ 🙂 🙂

    1. It’s not necessarily “well below”. That map indicates % chances of anomalies, which would in this case indicate a higher chance of below normal for the US Northeast, but not necessarily well below normal. I think we’d avoid the well below normal because of a lot of onshore flow from an ocean that is running near to slightly above normal, so the impact from it would be a bit modified. However, it’s a pattern that may feature a lot of cloud cover and potential precipitation, which would certainly prevent us from getting full benefit from solar radiation, thereby increasing the chances we’d run below the seasonal normal.

    1. So if the GFS is broken it’s wrong. But yet it’s still likely. He’s confusing. 😉

      It’s just a snowy spring pattern. It happens. It actually snows there more in fall & spring than it does during the winter. 😉
