DAYS 1-5 (MAY 20-24)

We’re still on the back-side of low pressure here with a cool breeze and lots of clouds, but today will be free of any rain threat. That low wanders away into the North Atlantic and high pressure holds to our north through midweek. A redeveloping omega block will send its eastern low pressure member our way to the south of the high pressure area mid to late week, resulting in another slow moving rain and wind event, along with a chill that’ll make it feel like much earlier in the spring than it is. We’ll start to see improvement, slowly, as we head through Friday and to the start of the weekend, but the pattern is one that doesn’t allow the storm system to exit quickly, so we’ll still feel its effects during this time in the form of below normal temperatures, clouds, and a shower chance despite a drier trend.

TODAY: Lots of clouds / limited sun. Highs 56-63. Wind N 5-15 MPH, gusts 20+ MPH.

TONIGHT: Mostly cloudy. Lows 45-52. Wind NE up to 10 MPH.

WEDNESDAY: Cloudy. Chance of drizzle. Highs 52-59, coolest coastal areas. Wind NE 5-15 MPH, gusts 20-25 MPH coastal areas.

WEDNESDAY NIGHT / THURSDAY: Overcast. Rain likely. Areas of fog. Temperatures fall to 45-52 then steady. Wind NE 10-20 MPH inland, 20-30 MPH coast, higher gusts.

THURSDAY NIGHT: Overcast. Periods of rain / drizzle. Temperatures steady 45-52. Wind NE 10-20 MPH, higher gusts.

FRIDAY: Mostly cloudy. Additional showers / drizzle, tapering off with time. Highs 52-59. Wind N 10-20 MPH, higher gusts.

FRIDAY NIGHT: Variably cloudy. Chance of a shower. Lows 43-50. Wind N 10-20 MPH, higher gusts.

SATURDAY: Lots of clouds / some sun. Chance of a shower. Highs 57-64. Wind N 10-20 MPH, higher gusts.

DAYS 6-10 (MAY 25-29)

Upper level low pressure weakens but hangs around during the May 25-26 Memorial Day Weekend time period with a daily chance of diurnal showers. However much of the time will be rain-free, albeit continued cooler than normal. A brief break May 27? Watching another low pressure area and rain threat potential for later in the period with continued below normal temperatures.

DAYS 11-15 (MAY 30 – JUNE 3)

Wet weather threat early in the period then a drier trend with a gradual shift from a blocking to more progressive pattern. Temperatures near to below normal. Day-to-day details TBD.

  1. Thanks TK
    I wonder if we will see a record low high for the high temperature for Thursday. Whether that happens Thursday just looks nasty.

    1. Boston’s record low max for Thursday is 47, set in 1909., Worcester’s is 46 set in 1909. Blue Hill is 44 also set in 1909.

      It’s going to be tough to break those, especially Blue Hill.

  4. Good morning and thank you TK.
    What a dreay disgusting out look for the rest of the month.
    Exactly why I HATE Spring in New England. Simply dreadful!!! I mean I can’t stand it.

    50 now, 49 earlier.

  5. Thanks TK. And to think I was worried about air conditioning. Seems like we could still be having fires. Quick question: what do you see as max winds in the Natick area over the next few days? Will the higher numbers be along the coast? Thanks.

    1. Higher coast, yes… 35-40 top gusts Boston, 45-50 top gusts Cape Cod.

      30-35 top gusts inland.

      1. One quick follow-up: is Natick considered inland? Doesn’t seem like we are on the coast nor are we bordering Worcester.

        Happy birthday. I appreciate your taking the time on your special day.

  6. I was telling someone yesterday how much I love upper level low pressure areas and blocking patterns, and they thought I was being sarcastic. 😉

  14. Thank you TK and Happy Birthday!

    Chilly walk along the shore this AM with northerlies. Thinking that VT, no NH, and maybe top of the Berkshires might see a little snow. Not sure but it seems enough cold air will be in place.

    Noticing the TV mets referring to Thursday event as a nor’easter as often as they can. Could be technically right, but the hype is there.

    2. Technically, yes.

      The term, however, it’s often used more for eye and ear candy.

  17. Thanks, TK!

    Happy Birthday to you and Mark!
    Enjoy your special day, amigos! 🙂

  18. Happy Birthday, TK!

    Hope you have a splendid day.

    Also, enjoy the upper-level low pressure area and blocking pattern.

    Snow will begin falling in the Presidential Range Wednesday, according to the Mount Washington Observatory: “Another round of showers is expected to move into New England late on Wednesday and continue overnight as a low pressure system approaches from the west. Since summit temperatures should remain around the mid to low 20s on Wednesday, precipitation should fall in the form of snow at the higher summits in the late afternoon and overnight.”

  20. I’m here at MCO Orlando going to be a bit of a shock to the system when I step off the plane at PVD.

  25. Thanks, TK. And Happy Birthday to you! Also Happy Birthday, Mark!

    It is so raw and lousy out. I will be on the road on Thurs. Not looking forward to the rain and wind. Bring back the sun and warmth!

  34. Happy birthday TK and Mark!

    I cleaned the gutter drains of tons of tree debris just in time it seems lol.

  35. I can just picture everyone in Heaven turning towards the Pearly Gates this morning and yelling, “Norm!” 🙂

    1. Thursday nights were incredible.

      At one point it was, I think ….

      Cheers, Wings, Seinfeld, Friends ???? It was 2 solid hrs of awesome shows.

    2. I had the exact same picture in my head. I suspect there is a lot of NORM heard round the world too

  36. Happy Birthday, TK, and thank you for the forecast and education gifts you give us every day.

    And, Happy Birthday, Mark. (Will you try to ski this weekend in celebration?) 😉

  38. Happy birthday, TK from Missouri City, Texas where it is 90 with 76 dp.
    Like Robert, we will have system shock when we arrive in Providence Sunday afternoon.

  39. Thanks TK and Happy Birthday!

    Contrary to popular belief, I do not share a birthday with TK. My birthday was actually back on April 19 but thank you all for the birthday wishes anyway!
