DAYS 1-5 (APRIL 18-22)

High pressure slides offshore today as clouds increase ahead of a warm front. This warm front, extending from low pressure destined to pass to our north early this weekend, may produce a brief episode of light rainfall tonight, especially in southern NH and northern MA. While clouds linger Saturday morning, we’ll eventually see more sun develop and a preview of summer as it becomes the warmest day of the year-to-date. But not-so-fast along the South Coast of course where a southwesterly wind comes off much cooler ocean water, and those areas will not share in the summer feel that other areas do. A rain shower may accompany a cold front as it goes by Saturday night, and Sunday (Easter for those celebrating) will be a fair, breezy, and less-warm but still-mild day. High pressure will build over the region slackening the wind by late in the day and this high will do its best to hold on for fair weather for the Patriots Day Red Sox game and Boston Marathon on Monday, but by day’s end clouds will re-take the sky and we’ll have our next threat of rain showers. Unsettled weather will be with us into Tuesday as low pressure crosses the region. A redevelopment of this system may enhance rainfall somewhat – but those details are still to be worked out. Improvement should take place later Tuesday assuming the timing of the system is as currently expected.

TODAY: Sunshine filtered to dimmed to blotted out by increasing clouds. Highs 55-60 coast, 60-65 inland. Wind SE up to 10 MPH.

TONIGHT: Mostly cloudy. A brief period of light rain possible, favoring areas north of I-90. Lows 46-53 evening, then slowly warming overnight. Wind SE up to 10 MPH shifting to SW 5-15 MPH.

SATURDAY: Mostly cloudy morning. Mostly sunny afternoon. Highs range widely from 58-65 South Coast (even cooler Outer Cape Cod / Islands) to 75-82 interior locations. Wind SW 10-20 MPH, higher gusts.

SATURDAY NIGHT: Variably cloudy. A brief passing rain shower possible. Lows 46-53. Wind SW 5-15 MPH with higher gusts, shifting to NW.

SUNDAY: Sun and passing clouds. Highs 58-65. Wind NW 10-20 MPH.

SUNDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 5-15 MPH.

MONDAY: Partly sunny. Highs 55-62, coolest coast. Wind NW up to 10 MPH becoming variable with coastal sea breezes developing.

MONDAY NIGHT: Mostly cloudy with a good chance of rain showers. Lows 48-55. Wind SE up to 10 MPH.

TUESDAY: Mostly cloudy with a chance of showers and a period of steadier rain possible, ending later with breaking clouds and partial clearing. Highs 57-64. Wind variable 5-15 MPH becoming W late.

DAYS 6-10 (APRIL 23-27)

Unsettled weather chances April 24 to early April 25, April 26 to early April 27. Unclear on the details of either of these threats at this point. Temperatures variable, averaging out near normal.

DAYS 11-15 (APRIL 28 – MAY 2)

No changes to this outlook. Battle zone pattern between a chilly eastern Canada and warm US Southeast. Additional unsettled weather and variable temperatures.

  1. Thanks, TK!

    31 frosty degrees at 6:30!

    Paul Revere’s Ride
    By Henry Wadsworth Longfellow

    LISTEN, my children, and you shall hear
    Of the midnight ride of Paul Revere,
    On the eighteenth of April, in Seventy-five;
    Hardly a man is now alive
    Who remembers that famous day and year.

    A poem that I, and probably some of you, had to memorize in grade school!

    1. 250 years

      Not a bad run. We are not perfect, but what an amazing great American experiment thanks to what I believe was 56 men with uncanny foresight.

      2. “America is an idea. Ireland is a great country, but it’s not an idea. Great Britain is a great country, but it’s not an idea. That’s how we see you around the world, as one of the greatest ideas in human history.” ~ Bono from U2 in 2012.

  3. Good morning and thank you TK

    36 earlier this morning, now has recovered to 53 already!

    Last night, Eric had 84 for Boston tomorrow. Seems a tad high, but we shall see. 🙂

    1. TK and I had a conversation yesterday about Saturday’s temperatures. Here’s what I said and he agreed:

      What’s really going to happen is 1 of 2 things:

      1. We stay cloudy all day with a few showers, and nobody gets above 72-75.

      2. It goes partly to mostly sunny in the afternoon with gusty SW winds and places like BED and FIT jump to 85 or 86.

      Because that’s the way it always is.

  6. Thank you TK!

    Happy Friday to WHW Nation!

    Happy Birthday to JimmyJames and SouthCentral!

    1. High pressure !!

      He was a really really good meteorologist and always enjoyed watching his weather cast.

      1. I have no idea why he looks sort of familiar but I don’t remember him

        I admit I also thought you meant AI (I not L) present the weather. We might have to start using the preferred ed dept’s A1.

  10. Departing from the arctic on the Norwegian Jewel for Bermuda this afternoon. We liked it so much last year, we’re going again. 🙂

    1. YAY Tom! Enjoy Shall we watch the Bermuda Web Cam to see if you depart the ship?

      Will you be at the Royal Navy Yard again? Or Hamilton?

      1. Royal Navy Dock, noonish Sunday to 5pm Tuesday. 🙂

        We have plans to go off ship all 3 days.

    2. If you’re looking for something to kill just a couple of hours, I highly recommend the Bermuda Aquarium, Museum, and Zoo. (https://bamz.org/)

      We visited it on our last trip to Bermuda and it was great.

      Also, if you’re looking for a decent meal just off the ship, we loved the Bone Fish Bar & Grill. (https://bonefishgroupbermuda.com/) It’s right in the Dockyard and reasonably priced.

      1. We were about to do the aquarium and had a look around and decided, nope not for us. 🙂 Looks like a missed a good take.

  13. What a pleasant surprise today is. A couple of Mets had clouds in here today but there has been nothing but brilliant blue sky with some scattered high clouds. We were at the Daffodils field at Parson reserve today in Dartmouth – packed! The seabreeze even feels refreshing with the warm April sun..-and this all comes on a holiday. bonus!

    2. No surprise from my perspective…

      “Sunshine filtered to dimmed to blotted out by increasing clouds.”

      Exactly how it happened. Exactly how I expected it to happen. 🙂

  14. It’s still 4 days off but I’m already starting to lean away from the “period of steadier rain” potential toward something more like a quicker round of rain showers for next Tuesday.

    In fact, looking ahead, I don’t see a lot of really wet weather, which is not great news regarding fire season (which still has a couple weeks to go) or long term drought relief.

    To add to that further, CPC’s long lead forecasts show a general drying trend fairly widespread across the US during the next year. Not that long range forecasting is something you can hang your hat on, but it’ll be interesting to watch the trends.

  15. In the shorter term, both the RRFS & HRRR short range guidance now indicate that considerable cloud cover is going to linger for a longer time tomorrow, perhaps as late as mid afternoon in eastern areas. This will have an impact on high temperature, keeping them from reaching full potential.
