DAYS 1-5 (AUGUST 23-27)
A change in the weather pattern means goodbye to summer heat, for now. Just like when we have a mild spell in late February and some jump the gun calling the snow season over, you definitely don’t call the summer heat season over when August still has time to go and September lies ahead. We all know better. And we’re not done with summer heat. We just won’t see any during this 5 day period. Instead as high pressure builds north of the region then gradually slips southeastward, we will start with a northerly air flow today into Saturday, becoming more easterly during late weekend and early next week. Aside of a wave of low pressure causing some morning showers in southeastern portions of the region this morning, and the risk of a patch of drizzle near the eastern coastal areas during Sunday, it will be mainly dry through Monday. Going to stay with a dry forecast for Tuesday but that will depend on the speed of a front creeping back in this direction from the south as well as potential low pressure off the Mid Atlantic Coast, which may or may not have some tropical characteristics to it. For now, I think neither of this are an impact for the end of this period. We’ll also be watching a broad trough in the Midwest by then but that should still be far enough west to not have any impact as well.
TODAY: Mostly cloudy early to mid morning with lingering showers eastern and southern MA, RI, and eastern CT. Clearing midday-afternoon. Drying out. Highs 78-85. Wind NW 5-15 MPH.
TONIGHT: Clear. Patchy fog interior low elevations. Lows 55-62. Wind light N.
SATURDAY: Sunny. Highs 75-82. Wind N 5-15 MPH.
SATURDAY NIGHT: Partly cloudy. Patchy fog interior low elevations. Lows 53-60. Wind light NE.
SUNDAY: Variably cloudy with areas of fog and a slight chance of patchy drizzle coast. More sun inland. Highs 68-75, coolest coast. Wind E 5-15 MPH.
SUNDAY NIGHT: Variably cloudy with areas of fog coast. Partly cloudy with patchy fog inland. Lows 55-62. Wind E up to 10 MPH.
MONDAY: Partly sunny with areas of fog coast. Mostly sunny inland. Highs 70-75 coast, 75-80 inland. Wind light E.
MONDAY NIGHT: Partly cloudy. Lows 58-65. Wind light SE.
TUESDAY: Increasing clouds. Highs 70-77. Wind light SE.
DAYS 6-10 (AUGUST 28-SEPTEMBER 1)
The combination of a broad trough to the west, high pressure east of New England, and low pressure south of New England increases humidity and the risk of wet weather August 28-29 before we transition into a warmer regime with continued high humidity and drier weather but still the risk of a few showers/storms at times.
DAYS 11-15 (SEPTEMBER 2-6)
Midwest trough may flatten out and push eastward with a few showers then some drier air briefly, but the overall regime is still warm/humid with limited shower chances as it looks now. Still not the highest confidence forecast and will adjust as necessary.
