DAYS 1-5 (OCTOBER 28-NOVEMBER 1)
High pressure provides one more very pleasant autumn day today, then a drastic shift takes place during Sunday as a cold front approaches from the west, low pressure forms on it off the Mid Atlantic Coast, intensifies while tracking northward up along the front into a powerful low pressure area, and also links with a tropical system to the south taking in some of its moisture. This combination will lead to a 2-part wind event and heavy rain event, with the strongest wind from the southeast ahead of the low, a lulling as it goes across the region Sunday night as the heaviest band of rain comes through, and a pretty significant westerly wind behind it as it dries out during Monday. By Halloween on Tuesday it will be breezy, chilly, but dry with wind settling down by evening. As November gets underway, we’ll start it with a chill in the air.
TODAY: Early fog dissipating interior valleys. Mostly sunny. Highs 63-70. Wind S up to 10 MPH.
TONIGHT: Increasing cloudiness. Lows 50-57. Wind S up to 10 MPH.
SUNDAY: Mostly cloudy. Passing brief light rain showers possible, favoring RI and eastern MA through mid morning, then anywhere after 2PM. Highs 60-67. Wind S to SE 5-15 MPH, higher gusts by late in the day.
SUNDAY NIGHT: Overcast with moderate to heavy rain arriving evening then departing before dawn with general rain amounts 1-3 inches likely. Local flooding, especially on streets and in parking lots with leaf-clogged storm drains. Leaves on roads will make them slippery as well. Lows 53-60. Wind SE 15-25 MPH with gusts 35-50 MPH central MA and southwestern NH, and 25-35 MPH with gusts 45-60 MPH elsewhere.
MONDAY: Mostly cloudy with passing rain showers morning. Partly sunny afternoon. Highs 60-67. Wind S shifting to W 15-25 MPH gusting 35-45 MPH.
TUESDAY: Mostly sunny. Lows in the 30s. Highs in the 50s. Evening temperatures in the 40s. Breezy during the day, less wind evening.
WEDNESDAY: Partly sunny. Lows in the 30s. Highs in the 50s.
DAYS 6-10 (NOVEMBER 2-6)
Current timing suggests warm frontal passage with lots of clouds and a risk of light rain November 2, a cold front passing with a few rain showers then windy and cooler November 3, a fair weekend November 4-5 with a chilly start and mild finish and still milder November 6 as the jet stream lifts to the north of the region.
DAYS 11-15 (NOVEMBER 7-11)
Minor systems bringing mainly surface airmass changes but overall a milder than average temperature pattern expected as cool air masses from the north are prevented from fully impacting the region in a somewhat zonal pattern but a slight trough West / ridge East configuration.
