High pressure south of New England is beginning to wrap in a milder SW wind on today with highs climbing back into the mid 70's, with Lwr 70's at the coast. This afternoon will have us all dancing in the streets with the above normal temperatures and surge of mild air. SW winds will persist Thursday night with increasing cloud cover. Expect a very mild evening with lows dropping into the 40's to near 50.
A cold front approaches on Friday. SW winds ahead of the front will keep it mild with highs again in the mid 70's! Skies will likely be mostly cloudy, with a few breaks of sun possible. Scattered showers will likely begin to pop during the afternoon with the risk of even an embedded thunderstorm. The best chance will be later in the day. There will be a chance of a few showers right into Friday night, as it will take until dawn Saturday to finally get the cold front off the coast. I can not completely rule out early showers at the coast Saturday morning. Morning clouds will break Saturday giving way to increasing sunshine with Breezy NW winds following in Saturday morning. High pressure builds for the afternoon and delivers another shot of seasonal air back into the region with sunshine and highs in the 50'sand lwr 60's
Sunday will be another beauty with sunny to partly sunny skies by afternoon and highs near 60. Another weak cold front will approach Sunday night and early Monday morning. This will come with more clouds and a chance of a shower. Behind this front, even cooler air will follow in for the start of next week. After a damp, cloudy start, Monday will see skies turning partly sunny with highs will only be in the mid 50's.
A pronounced boundary separating the cooler states (us) from the warmer states (South) will become established as showers and areas of low pressure will develop along these differing airmasses. Our first round on the boundary train arrives Monday night into Tuesday in the form of showers, and even the potential for heavy rain as a low will ride along the boundary and track across southern New England. It may even mix with wet snow upon it's early arrival with the best chance of flakes in the northern mountains. Rain will be with us Tuesday morning before pulling away and drier seasonal 50's return for the midweek...Wednesday & Thursday. The weather looks to take a turn for the worse by the end of next week or next weekend...but we'll see on that. Moral of the story is today is awesome, so is this coming weekend! A cooler pattern will continue across the northeast for the rest of April thanks to a persistent trough, all part of a blocking pattern which continues. Last week we were in the ridge for days, now we will be in the trough for days. Such is life. Enjoy the mild 70's while they are out there!
