DAYS 1-5 (OCTOBER 13-17)

High pressure will be in control with generally fair weather through Friday. A couple of disturbances trying to push into the region will bring clouds at times including a couple of dissipating troughs today and again Thursday, then a warm front passes through the region during Friday evening. Temperatures will continue to run above normal through Saturday, at which time a stronger cold front will be approaching from the west, likely passing through the region during Saturday night / early Sunday, bringing showers and possibly a few thunderstorms as well. This will be followed by a breezy and cooler end to the weekend with a stronger westerly air flow behind the front.

Unsettled weather possible with a low pressure system approaching from the west later in the period.

  7. Thank you, TK.

    What a glorious stretch of weather. Not unusual, however. I’ve always found October to be one of the most predictably nice weather months of the year in Boston. There have been exceptions like 1996 and 2005. But generally, we often have fairly long stretches of sunny and dry weather. Tranquil, too.

  9. In case anyone missed it, with the talk about first frosts, I posted some of the first frost and first flakes data for Lowell very late last night:

    1st Frost data for Lowell:
    Average date: October 16
    Earliest date: September 21, 1962 (and 1973)
    Latest date: November 16, 1979

    1st flakes in Lowell:
    Average date: November 13
    Earliest date: October 8, 2001
    Latest date: December 16, 1973

    1st measurable snow in Lowell:
    Average date: November 26
    Earliest date: October 10, 1979
    Latest date: January 13, 2000

    This is based on snowfall data I have for Lowell back to 1929, and temperature data back to 1889.

    1. BTW, if you want an interesting fall, look at 1979. For Lowell at least, we had 1.5″ of snow on October 10, earliest measurable snow on record, and at the time, earliest flakes on record. Just 12 days later, October 22, it hit 90, the latest 90 on record. A full 25 days later, it dropped to 29, the latest date on record for the first 32-degree reading of the season. As a whole, fall (September-November) was the warmest on record for Lowell (0.1 degrees warmer than 2012), with below normal precipitation and snowfall). The winter (December-February) was the driest on record (rainfall data goes back to 1826), and the 3rd least snowy, while ending up warmer than normal. Snowfall as a while (October-May) was the 2nd lowest on record, with only 15.5″ for the entire season. (1991-2020 normal is 61.5″) Of course, we all know about the following summer too.

  14. Thanks SAK for the info!

    Hey JPD! I’m registered for the conference. I miss the in person ones but I know why we can’t do it yet. Looking forward to the virtual one!
