Friday Forecast

50 Comments

7:41AM

DAYS 1-5 (MARCH 23-27)
A large circulation of low pressure will spin off the Atlantic Coast for the next 5 days. Some instability on the back side of the upper low offshore will bring the chance of a few snow and rain showers to the region later today. A stronger spoke of energy will bring a better chance of rain/snow showers later Saturday then snow showers Saturday night into early Sunday which may result in some minor accumulation. Drier air means more sun for Monday-Tuesday with the low further offshore and high pressure trying to build in from the west.
Forecast details…
TODAY: Partly to mostly cloudy. A passing rain or snow shower possible. Highs 38-44. Wind NW 5-15 MPH.
TONIGHT: Mostly cloudy. Lows 27-34. Wind NW 5-15 MPH.
SATURDAY: Mostly cloudy. Scattered rain/snow showers, especially in the afternoon. Highs 38-44. Wind N 5-15 MPH.
SATURDAY NIGHT: Cloudy with snow showers likely, accumulation of a coating to 2 inches possible. Lows 24-30. Wind NE 5-15 MPH.
SUNDAY: Mostly cloudy with snow showers possible in the morning. Partly cloudy afternoon. Highs 33-39. Wind NE to N 5-15 MPH.
MONDAY: Partly cloudy. Lows from the upper 10s to middle 20s. Highs in the 30s.
TUESDAY: Mostly sunny. Lows in the 20s. Highs in the 40s.

DAYS 6-10 (MARCH 28-APRIL 1)
A weakening system may bring some cloudiness March 28 as it stays cool. Milder air arrives March 29-30 with fair weather on March 29 and a chance of rain showers on March 30. Drying, windy, colder March 31. April 1, based on current timing, should be fair and a little milder.

DAYS 11-15 (APRIL 2-6)
The flow looks more progressive but we may set up a battle between Canadian cold and southern US warmth which could turn it more unsettled here. Still possible that a stronger push of cold air from Canada may win.

  1. Tk you made mention of a coating – 2 inches is this the case in the medical area as remember a suger coating will get a call in and I have important plans celebrating my dads 70th birthday. Thanks

    1. Interesting. Hope all goes well for you.
      I am actually older than your dad. Crap, I’m ancient!

  2. Good morning and thank you TK.

    Beautiful day. Warm March sun shining with birds chirping away.
    Love it.

  3. Good morning, everyone!
    Thanks, TK!

    Happy birthday to your dad, SSK…Have a great celebration!

      1. I happened to see Danielle Niles forecast this morning and the simulated radar she used in her presentation.

        There are a few on and off waves of light snow to pass through overnight Saturday night and one Sunday very early morning. The last one looked like it had the best potential along the disturbance or trof axis.

        Hopefully, ground will be too warm.

        Do you have any sick or vacation days if it came to that ?

  5. Hope your not called in on Saturday SSK, Pattern looks active and cool. I do not see much in the way of snowfall, but cool temperatures will probably stick around through Early April.

    Top link is tropical cyclone Nora, expected to hit Queensland Australia as a cat 3

    2nd link is tropical cyclone Marcus, which days ago significantly impacted Darwin on the north coast of Australia …. then it moved due west, then turned south and now southeast and is headed in the relative area of Perth. It looks like it may be transitioning to a mid latitude cyclone. I think Perth getting hit would be like San Diego getting something. It can happen, but not frequently.

  8. TK wanted to say thanks for the post yesterday. Been slammed at work so I didnt get a chance to. (I work at the rmv lol)

  10. Not a bad early spring day. A little chilly, but the wind is light, and in the sun feels pretty good.
    I’m not in Boston, but its 48 here. Bout normal/average actually.

  11. RMV…….
    I’ll let you stay since I’ve known you for about a quarter century. 😉

    And you’re welcome! Glad you enjoyed. 🙂

          1. Zonal flow is generally defined as low amplitude, progressive west-to-east flow of the jet stream.

            1. Not quite. You can get prolonged frozen events in zonal flow if you line up surface features correctly. Sometimes if a front sets up parallel to the flow, trouble results.

        2. Dud on me!!! I was looking at the surface features and ignoring the 500 mb height contours. Silly me!

          Sorry.

        1. Coating to 2 inches, but they will also linger off and on in bands well into Sunday.

            1. Whatever takes place for accumulation will be done by 8AM Sunday, even if it snows after that.

                1. Probably when it’s occurring. We will have an initial widespread wave of snow and then bands will set up. I have no way to know where those bands will be until they start forming.

    2. That’s nothing new. Early April is always nasty, most of the time.
      I just hope by school vacation week (haven’t they had enough vacation this winter) it’s at least low to mid 50’s.

  14. A couple of the short range models have a few 4 inch snow totals for Sunday morning in isolated locations of eastern MA.

    1. Eric on ch 4 also had a small contour of a few towns getting up to 4 inches on grassy surfaces. It was, of course, on the south shore. 🙂 Where else 🙂

      1. That would mean that Boston could potentially reach the 60-inch mark for the season. Maybe Dr. Cohen wasn’t far off (64″) after all.
