Although changing air in New England this weekend is fairly commonplace for early fall in the Northeast, the clashes and collisions of different air will mean some changeable weather.
We start with cool, crisp sunshine Friday and an easterly breeze that will keep the coast a bit cooler than interior, but not by much. After all, the ocean water is 65 to 70 degrees! Nonetheless, the large dome of high pressure that brought Friday morning lows in the 30s for all states in New England (except Connecticut and Rhode Island) will still exert influence overnight Friday night.
That makes for many low temperatures in the 40s with some 30s in colder valleys.

To our west, a storm center moving east across Southern Canada will induce a southerly wind ahead of it, carrying warmer air toward New England for gradually increasing clouds from west to east late Friday night. This will be after most communities enjoy a view of the full Harvest Moon.
While some limited sun is probable in the first few hours of Saturday morning for Eastern New England, clouds will take over for one and all with scattered showers developing in Northern New England during the morning. They will likely continue off and on through the afternoon.
Meanwhile, Southern and Central New England see a midday or afternoon sprinkle with the higher chance of scattered showers during the late evening and overnight Saturday night as the Canadian storm passes to our north.
After early morning showers depart Cape Cod, sunshine returns Sunday, bumping temperatures through the 70s and even into the 80s for some in Eastern and Southern New England.
Expect one more disturbance to carry scattered showers through New England late Sunday night and Monday, then most of next week looks great in our exclusive First Alert 10-day forecast. We’re facing a cool shot at midweek and warming by week’s end.
The only thing we really have to be careful for is when the door to warmth opens at the end of next week. It’s not impossible to open a door the tropics, as well, so if anything is near the Eastern Seaboard, we’d have to be on guard.
We’ll keep close watch, as always.
