You may have noticed the feel of fall has been creeping into New England a little ahead of schedule. Even though the Autumnal Equinox is not until Saturday at 10:49 AM…a significant shot of unseasonably cool air is ready to return to New England.

Plenty of clean up out there this morning with numerous reports of downed trees and branches. Scattered power outages too thanks to the 40-50 mph wind gusts last night. The heaviest rain produced a 1-2″ rainfall in the downpours with some areas in the Berkshires picking up close to 3″. The rain is shifting off the coast with a cold front. Clouds will be in place through about 10 or 11 AM…before a sharp clearing line will be working towards the coast by lunchtime. Temps have been cooling behind the front this morning into the 50’s and Lwr 60’s. Once the sunshine comes out in full this afternoon, temps will give another run towards 70-72 degrees, but will start to fall later in the day with the lowering sun angles and breezy NW winds pushing in the much cooler air from Canada which will settle in tonight.

Frost advisories are up across the N & W for typical cold sheltered valleys which will drop into the lwr-mid 30’s overnight. Most will fall into the mid 40’s with downtown Boston holding in the Lw5 50’s . High barometer cool air will be sliding over New England Thursday. The high will be  wrapping in a cool NE wind which will keep temps only in the Lwr 60’s at the coast and mid 60’s inland. This will be the coolest air of the early season…and just another reminder that this summer really is over. Ouch. A weak ridge will remain in place through Friday providing more sunshine and seasonably cool temps near 70-73 inland. At the coast, temps will hold in the 60’s. We will have to watch a cold front stalled off the coast, which has been showing signs of backing in towards the coast. Increasing clouds at the coast Friday with brighter skies inland is the call. There is even the risk for a few spotty showers on the Cape with a wav of low pressure just off the coast.

SW winds will return on Saturday which will help to push the stalled front further off shore. Sun and clouds Saturday with a warmer feel in the mid 70’s. A cold front will push through Sunday with more clouds, a few showers and another shot of cool to follow heading into next week. T trough will persist in the east for the rest of the month helping to prevent any late summer or early fall warm up.
