DAYS 1-5 (JULY 8-12)

High pressure builds in today with fair weather and pleasantly dry air moving in. The high will sink to the south and allow it to heat up a little more on Thursday, but not to the levels of last week’s heat. While Thursday features mainly fair weather, I can’t rule out a stray thunderstorm wandering into areas mainly well west and north of Boston toward evening in response to a disturbance approaching from the west. This disturbance passes through at night, but with the loss of sunshine, fuel to sustain any storms will be lacking and I expect anything that did make it into the area to dissipate. On Friday, however, a cold front will move through the region during the afternoon and evening, with higher humidity in place ahead of it. This provides a better chance for a more widespread shower and thunderstorm occurrence. The front does sweep through Friday evening and night, and introduce fair weather and lower humidity for the weekend. As a high pressure ridge builds to our west, we may contend with some “spill-over” cloud cover by later on Sunday, otherwise it looks like abundant sun and a few fair weather clouds both weekend days.

TODAY: Early clouds mainly Cape Cod / South Coast, otherwise sunshine. Highs 80-87. Dew point falls under 60. Wind up to 10 MPH starts out N, shifts to E, then ends up S by day’s end.

DAYS 6-10 (JULY 13-17)

Watching the period from later July 13 to early July 15 for some higher humidity including shower and t-storm chances as low pressure passes north of the region. Fair weather returns later in the period. Temperatures slightly variable, averaging around normal.

DAYS 11-15 (JULY 18-22)

Overall pattern fairly seasonable but a little temperature variability with one or two shower / t-storm chances with passing fronts from the west. No sustained high heat indicated.
