DAYS 1-5 (MAY 26-30)

Upper level low pressure finally pushes off to the east today and high pressure moves our way from the west. There’s enough chilly air above us to still trigger the development of diurnal cumulus, but they won’t be as extensive and spread (stratocumulus) like yesterday, allowing a sun/cloud mix, and they won’t grow enough to produce showers here (that can take place but will be in the mountains to the west and north). After a cool start, it will be a pleasant day with generally light wind including a coastal sea breeze, where it will be a little cooler than inland as far as high temps go. Conditions are favorable for outdoor Memorial Day observances. High pressure builds and is in control for a stellar Tuesday – the pick of the week. After that things, cycle back to the weather being controlled by low pressure. Wednesday, a trough approaches and low pressure moves into the Great Lakes. Its warm front will approach our region, increasing the clouds. A period of rain with the passage of that warm front occurs Wednesday night. Thursday, we get into the warm sector of the low with a southerly air flow, higher humidity, and showers around, until a cold front passes by at night or early Friday. But Friday can see additional showers in the area as the Great Lakes low is stacking under its upper low which has to drift eastward across the region, so the air will remain unstable that day.

TODAY (MEMORIAL DAY): Sunny start except patchy clouds in western hills. Sun/cloud mix late morning on. Highs 63-70, coolest coast. Wind N up to 10 MPH with coastal sea breezes developing.

TONIGHT: Clouds dissipate. Lows 46-53. Wind N under 10 MPH.

TUESDAY: Mostly sunny. Highs 66-73, coolest coast. Wind N to E up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Lows 49-56. Wind E to SE under 10 MPH.

WEDNESDAY: Increasing clouds. Highs 64-71, coolest coast. Wind SE 5-15 MPH.

WEDNESDAY NIGHT: Cloudy. Chance of rain. Lows 53-60. Wind SE to S up to 10 MPH.

THURSDAY: Mostly cloudy. Chance of showers. Highs 66-73, coolest South Coast. Wind S 5-15 MPH.

THURSDAY NIGHT: Mostly cloudy. Chance of showers. Lows 55-62. Wind S 5-15 MPH shifting to W.

FRIDAY: Variably cloudy. Chance of showers and possibly a thunderstorm. Highs 66-73. Wind W 5-15 MPH.

DAYS 6-10 (MAY 31 – JUNE 4)

A low pressure trough aloft and a series of surface troughs bring a chance of showers (possibly thunderstorms) during the last day of May. Upper level low pressure gradually weakens and the flow becomes a little more zonal early days of June, but additional disturbances about June 2 and 4 can bring shower and thunderstorm chances.

DAYS 11-15 (JUNE 5-9)

Still a mixed bag in our guidance but the general outlook is similar to yesterday. Not high confidence but leaning toward a couple periods of unsettled weather but no major systems or significant temperature departures from the long term average.

  5. Thanks TK
    Remembering those who made the ultimate sacrifice for our country and those who are serving our country.

  6. 62 and still climbing.

    61 at the airport with West wind at 5 mph.
    Won’t be long before Logan switches to a sea breeze

    Ocean temperature 51.1 (Boston Buoy)

  8. Logan has switch to a very light sea breeze (ESE at 6 mph) and temperature has dropped from 63 down to 61.

    64 here.

    Many cumulus in the sky here, but sun shows off and on.

  12. Sox down 2-0. Bats are asleep!!

    On another note, the Sox played day games on Fri, Sat, Sun, today, and again this Weds. Has probably happened before but I can’t remember it.

    1. A make-up, a long weekend, and a getaway day. It’s happened before. 🙂

  13. Info on the late May snow event for Mount Wasington…

    Tied for 4th place in late May snowfall events, with 12.4 inches of snow and sleet since Wednesday night. The most recent comparable late season snowfall occurred June 4-10, 2023 with 8.4 total inches of snow. This event brought the snow total for May to 13.5 inches, a little over the average of 12.9 inches. They may add to this before the month ends.

    1. Didn’t quite pull it off. The teams today are very evenly matched. Pretty much identical records. (27-29, 27-28).

  15. 145 years ago today, May 26 1880, Boston set its all time high temperature record for May at 97F. Sizzle-sizzle-fry-fry.

      1. The climate has always changed and is always changing. Our earth has never been stable, and it’s not meant to be. You can thank the sun for that. 🙂

        1. So true. Sadly, this time it has a healthy dose of man’s destruction hurrying it along.

    2. May record for Lowell is 101 on 5/22/1992. They also hit 100 on May 21, 1975, which is the earliest 100 on record for the Mill City.

  17. Red Sox lose yet another 1-run game. How many has that been now? 🙁

    I am in no mood to count this stat.
