Put A Fork In Summer...Fall Is Here to Stay.
In some years, summer warmth can last into September and October...Not this year. In fact, the break down of the summer warmth began in August with a return of a trough to the Northeast...which has shifted west..and helped to break down the intense heat of the summer all the way back into the midwest. Now, record lows are being set with a deep trough in place which extends all the way south from the Northern Plains to the Carolinas. This trough is going nowhere fast thanks to an upper level blocking pattern and a negative NAO which is likely to last into Early October at least.
Cool High pressure sits over New England this morning with cool calm conditions. Temps in the 40's and 50's will be warming inot the 60's this afternoon. Light NE winds will keep it cooler at the coast 62-65, very similar to the current Ocean Temp. It will be slightly warmer inland 65-68 away from the onshore flow.
Off the coast there is a stationary front. A weak wave of low pressure will track from the Carolinas up the coast and come close to New England tomorrow. This will bring in a stream of clouds which will likely hug the coast Friday. Clouds off the coast will be backing inot Eastern MA. Clouds with NE winds will keep temps in the 60's. There is even the chance of some light showers on the Cape & islands or even a bit of drizzle at the coast if the clouds thicken enough. Brighter skies will be found inland where highs will be able to climb inot the Lwr 70's with the weak ridge of high pressure making for a nice day over all for many of us.
Not only is there a front off the coast, but there is a front to our west which will try to push eastward this weekend. Our friendly high pressure will do it's best to keep all of this inclement weather away from us as long as possible. On Saturday, low clouds around sunrise will break for increasing sunshine and warming SW winds develop. This will make for a warmer day for the first day of fall as highs will climb to 73 to 78 by the afternoon. A cold front will finally arrive by Saturday night which could trigger a few light showers or a brief T'storm inot early Sunday morning. After some early clouds/shower...I expect sunshine to be increasing by Sunday afternoon...but a bit cooler with building NW winds behind the departing front with highs near 70-75.
The trough will still be in place from the Great Lakes to the Northeast supplying another shot of cool fall like air..with temps back inot the 60's next week in the sunshine. What can you do summer lovers? It is time to embrace the change of season. The trough will finally lift out by midweek with a flatter flow to follow by next weekend (29th & 30th) and a broader trough in place for the east through October 5th. What this means is a nice pattern for the next two weeks with ample amounts of sunshine and no big storms. Temperatures will remain very fall like through out.
