DAYS 1-5 (APRIL 15-19)

A warm front moves through this morning. A cold front moves through this evening. All the while a trough of low pressure crosses the region and low pressure at the surface passes to our north. These are the ingredients for a cloud-dominated, unsettled day, but shower rounds will be somewhat limited to one this morning, one or two this afternoon and evening, and maybe a few isolated ones in between. Can’t rule out thunder and small hail in some of the stronger ones. It will be a mild day, but chilly air awaits and will be delivered by the cold front, setting up a chilly mid week for us. Wednesday will feature a gusty northwest wind and be the coolest day of the week, along with a fair amount of diurnal cloud development which will limit sun at times. As high pressure builds closer, Thursday will feature more sun and less wind. Our next low pressure system arrives later in the week, but again with segments of unsettled weather. Right now, the best bet is to expect an increase in clouds Friday, some nighttime warm frontal rain, a warm sector Saturday, but a rain shower and thunderstorm opportunity ahead of an approaching cold front. Details TBD for the end of the week and start of the weekend.

TODAY: Lots of clouds / intervals of sun. Isolated to scattered rain showers, and a slight chance of thunder including the possibility of small hail. Highs 57-64. Wind SW 5-15 MPH with gusts 20-25 MPH.

TONIGHT: Lots of clouds and an additional rain shower possible early, then clearing. Lows 38-45. Wind shifting to NW 10-20 MPH, higher gusts.

WEDNESDAY: A sun/cloud mix. Highs 48-55. Wind NW 10-20 MPH, gusts 25-30 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 28-35. Wind NW 5-15 MPH, gusty.

THURSDAY: Mostly sunny. Highs 52-59. Wind NW 5-15 MPH, diminishing.

THURSDAY NIGHT: Clear. Lows 32-39. Wind variable under 10 MPH.

FRIDAY: Increasing clouds. Highs 53-60, coolest coast. Wind SE up to 10 MPH.

FRIDAY NIGHT: Cloudy. Chance of rain. Lows 42-49. Wind SE to S 5-15 MPH.

SATURDAY: Variably cloudy. Chance of showers, possibly a thunderstorm. Highs 53-60 South Coast, 61-68 elsewhere. Wind SW 10-20 MPH, gusty.

DAYS 6-10 (APRIL 20-24)

Continuing the long weekend, expecting dry, breezy, cool weather April 20 and fair weather for Patriots Day April 21 with a cool coast and milder inland. Brief rain shower threat April 22. Fair April 23. May face a rain threat by April 24 with a battle between warm to south and cool to north.

DAYS 11-15 (APRIL 25-29)

Battle zone weather pattern between warm air to south and chilly air in eastern Canada. Potential for a stretch of unsettled weather and some larger temperature contrasts.

  6. Good morning and thank you TK

    Low this morning was 49 which was higher than any day time highs over this past weekend.

    currently 51

  9. TK you do think we will drop below 32 here in the city? 100% outside of the city into mid may but here I am not seeing cold enough air the next weeks and then climatologically the chance is very low as that would be the start of May. But I am sure I will be wrong lol

    1. Not TK and you know I posted something on the previous blog.
      IMHO, it is only 4/15, we are vulnerable for a freeze for a few more weeks yet, into early May. I am certain JP hits freezing again this season. Perhaps not Logan as they stick out into
      the water, but the neighborhoods almost for sure. Possible we are done, but I would NOT bet on it. 🙂

      Just my 2 cents. 🙂

      2. Took a look at yesterday’s 45-day run of the ECMWF. Of the 50 members, none show a low of 32 or colder at Logan after April 21. The same is true for BED. For LWM and OWD, they don’t show a low of 32 or colder after April 22.

        For Logan, using the mean of all 50 members, max temperatures are below normal from April 26, right to the end of the run on May 29. However, min temperatures are above normal from April 22, right to the end of the run on May 29.

        None of the 50 members shows any snow at Logan during the entire run.

        2. Thanks SAK, let’s see how it verifies. I noticed the euro does a good job verifying temps but not precip.

  12. I am going to stick out on a limb and say most of SNE is done with snow, even Worcester! Famous last words? 😉 ❄️

    I will say that we won’t be done with Canadian air masses anytime soon though with no real persistent warmth. Just warm enough to NOT snow.

      1. Yes, THANKFULLY we can around here. What I meant was “persistent” Canadian air masses that continually chill us during the spring.

    2. Well as I’ve been saying Boston / south is done for any meaningful accumulation. Maybe next year Boston can get some decent old fashioned storms.

      1. Except that you said this before the two snows we had just this past week. Traces of snow didn’t disappear here until yesterday

  17. Thanks TK.

    Not below freezing everywhere, but GFS has widespread 30’s for lows Thursday after the cold front moves through:

    And MORE accumulating upslope snow in the mountains. The ski season rolls on…

    As much as 3-6″ more possible from Stowe up to Jay Peak and the White Mountains.

  18. I posted pictures from our weekend at Jay Peak yesterday.

    Stowe is still also doing very well. Mount Mansfield snow stake depth still at 91″ and above average for this time of year:

    Depth at 3900′ mid mountain is still at 67″.

    Things looked like they were going downhill fast after a relatively mild and snowless March but things have really taken a turn in the other direction after a cold, snowy April thus far.

    1. The sun has been out for about an hour here. Might add some juice for a few rumbles of thunder later on.

  20. Keeping an eye on NH trail reports for hiking purposes. Most reports say muddy, snow, ice and micro spikes needed for climbing. Rather wait til mid May.

  22. Today’s CPC has backed the warmth off considerably with the most now confined to the Deep South.

    1. This trend will continue.
      High pressure in eastern Canada is NOT a warm pattern for us in the spring. Yes we can get warm days (like today, and like Saturday will be) but the predominant pattern is cool.

      And it doesn’t matter how warm the upper pattern looks. It’s about what’s going on at the surface when you still have snow cover in eastern Canada and sit next to an ocean with water temps in the 40s to lower 50s.

      Been doing this a while. I notice these things. 😉

      1. I don’t have an outside thermometer but it has gotten quite chilly. Sky was amazing for awhile. Just cloudy now. Seems like a little rain w/maybe a little hail. I am really enjoying this. Last summer Marc and me were in and out of hospital and didn’t notice much. Wonder if there were some big storms last summer.

  25. The line is approaching me now. Time lapsing it from the 3rd floor, looking west, where I have a view all the way to the horizon.

  26. On a non-weather note, still seeing tons of social media posts from fair weather Sox fans about how bad they are, and how the season is “done”. This is where the clueless separate themselves out from those who actually understand.

    Yeah, there are 162 games in the season. And you’re going to judge it on the first 2 weeks. Laughable.

    So how are the teams in the division doing in comparison?

    Let’s take a look at some win-loss records.

    Blue Jays 9-8
    Yankees 9-7
    Red Sox 8-10
    Rays 8-8
    Orioles 6-9

    Oh wow. I guess those are the 5 teams who suck and their seasons are over.

    Carry on!

    1. You could turn a blind eye from those social media posts lol. People are actually calling the season an end? That’s funny! Personally I haven’t seen much of it but then again I skip over that nonsense. They do need to fix their defense though! Worst in the MLB think with 19 errors already? Not good.

      1. I generally do turn a blind eye for the most part, and often advise others to do the same with silliness, but when you see them left and right it’s kind of hard not to notice. 😉

        I do agree about cleaning up the errors. Those will haunt them in the long run.

    1. Losing 26-1 and 1-0 counts exactly the same in the W-L column. 🙂

      There are things that they can fix individually and as a team, and they’ll work on those. They’ll entertain us this season, and more positively than last season. 🙂

      1. I am aware that both count as a loss, but getting off toa fast start helps and provides a buffer. Lots of talk in the MLB these days about fast starts.

        Bruins last game tonight. (I thought it was the previous game.) The Bruins are looking for the next generation to take over. Gone are the days of Bergeron, Marchand, Lucic, Chara, etc. What is impressive about the Bruins over many years has been their on the ice and in the locker room culture. It has been the envy of other teams.

  29. We didn’t get much rain. The heavy bands fell apart and ended up with a light shower. Now the sun is coming back out!

  30. We had 0.16 in a very short time when all went thru. Blue sky and sun now fading to cloud cover covering about half the blue sky.

  31. Sorry if this was shared. Very sad

    The New England Patriots are deeply saddened to learn of the passing of Don Hasselbeck. We extend our heartfelt sympathies to the Hasselbeck family during this difficult time.

  32. Comments on FB saying Milford may have had a microburst. Of course not official but trees are down and a road(s) is closed.

  36. Quite the weather day – an illustration of what I always say about the volatility of spring. Without debate, the most changeable of all 4 seasons. It just is.

    For model watchers: The GFS is all kinds of messed up right now, and it’s quite confusing. The model is already way, WAY off just a few days into its operational run from 00z. Toss it. Useless. Not sure what’s up with it, but it’s usual uselessness is greatly amplified at the moment.
