DAYS 1-5 (OCTOBER 12-16)

High pressure will be in control with generally fair weather through Friday. Exceptions will be a fairly widespread moderate to dense fog across the region for part of this morning due to moisture trapped at low levels of the atmosphere, and a chance of a spot shower Wednesday from the leftovers of a dissipating trough moving in from the west. Temperatures will run above normal in this pattern not only through Friday, but Saturday as well. That day though is going to bring an increased threat for shower and even possible thunderstorm activity as a strong cold front approaches from the west, but at this point the timing would hold most activity off til evening.

TODAY: Foggy into or through mid morning across most of the region with less fog in parts of the Worcester Hills and across the Cape Cod area. Eventually increasing sun. Highs 65-72. Wind variable to S up to 10 MPH.

TONIGHT: Partly cloudy. Patchy fog. Lows 52-59. Wind S under 10 MPH.

WEDNESDAY: Partly sunny. Slight chance of a shower. Highs 68-75. Wind variable to S up to 10 MPH.

WEDNESDAY NIGHT: Variably cloudy evening. Partly cloudy overnight. Patchy fog. Lows 52-59. Wind S to variable under 10 MPH.

THURSDAY: Partly cloudy. Highs 69-76. Wind variable up to 10 MPH.

THURSDAY NIGHT: Mostly clear. Patchy fog. Lows 52-59. Wind variable under 10 MPH.

FRIDAY: Partly cloudy. Highs 70-77. Wind SW up to 10 MPH.

FRIDAY NIGHT: Variably cloudy. Patchy fog. Lows 52-59. Wind SW up to 10 MPH.

SATURDAY: Partly sunny. Showers and possible thunderstorms mainly late afternoon / evening. Highs 71-78. Wind SW 5-15 MPH.

DAYS 6-10 (OCTOBER 17-21)

A cold front clears the region early October 17 with that day seeing a gusty westerly breeze, drier/cooler air, and just the risk of a brief passing shower. High pressure dominates with fair weather and moderating temperatures October 18-20. Next frontal system and shower threat arrives around the end of the period from the west.

DAYS 11-15 (OCTOBER 22-26)

Westerly air flow with dry and seasonable temperatures expected for early period, then indications are for high pressure to re-build across the region with fair weather and a warming trend following.

  2. Thanks TK.

    Interesting that we are getting these nice stretches of Indian Summer temps before we have yet to have our first frost anywhere in SNE.

    Has NNE had their frost yet?

  7. Thank you, TK.

    Philip, I don’t think NNE has had a frost, which is remarkable this late. North of Caribou they’ve had a few nights in the upper 30s. Of course, in the higher elevations above 5,000 feet there’s been frost. But that doesn’t really count.

    1. I just hope Boston will see a first frost by New Year’s Eve.

      I do wonder though what date is the latest first frost?

  9. Mark and JimmyJames, my son, bride and his son camped in NW Connecticut this past weekend. They visited a few areas managed by Steep Rock Association. What an amazingly beautiful area. JJ, I think this is pretty close to you ??

    A few photos…..

  10. Philip, you are correct about Boston’s first frost occurring usually in the first week or so of November. We will have frost in November, for sure, and December, too. Heck, even in 2011-2012 we had that. I remember celebrating Thanksgiving in November 2011 in Western Massachusetts and seeing the rooftops covered with a light snowfall. It wasn’t very cold, but certainly cold enough for frost that Thanksgiving (also in Boston).

    1. Here in JP, first frost is WAY before Logan’s
      Usually sometime in early to mid October, but sometimes
      late September.

      1. 73 here in JP. I just took the trash out to the street and it
        feels like Summer! A beach day, even. 🙂

  12. South Sutton had its first Frost Sept 20 or right around there last year. I came across a memory FB photo a few days ago. It wasn’t a freeze. But we had a couple of them

  13. Some interior valleys are going to frost for the first time sometime next week (probably Tuesday morning – Oct 19).

      1. Frosty skeeters are dead skeeters. And as much of a nature lover as I am, I don’t give mercy to skeeters! Sorry skeeters! 😉
