The old system responsible for the severe weather outbreak and all the rain and snow across the country this week is now a shadow of its former self.
This shadow is crossing New England, it is an upper-level cool pool. A cool pool aloft creates instability in the atmosphere which results in heavy cumulus clouds and some scattered showers and or a sprinkle. It is also good for scattered rainbows at sunset.
It is breezy this afternoon with temperatures in the 50s in our 60s, wind from the west 15 to 25 mph with higher gusts.
Shortly after the sun goes over the horizon the sky will clear quickly, a big bright flower moon in the sky with a cold night.
Patchy frost is likely by morning with temperatures reaching the 20s in the coldest hollows, to 30s and 40s in the more urban and/or coastal areas.
High-pressure overhead tomorrow morning with sunshine. As the high moves offshore, increasing clouds in the afternoon. Temperatures tomorrow a little bit warmer inland near 65° with a light seabreeze it'll be cooler at the shore.
For Friday we are monitoring a powerful storm to be moving up the Appalachian Mountain chain. Rain will develop from west to east during the day into the state of Maine by mid afternoon.
Then we have about 18 to 24 hours of rain that is heavy at times with the rainfall amounts exceeding 1 inch for most of New England.
Wind at the shore may go to gale force from the east for a time on Friday, before becoming lighter and more southerly Friday night and Saturday. Temperatures on Friday in the 50s, but back up to lower 60s for much of New England for Saturday and Sunday. Most of the weekend features clouds with occasional showers, but the heaviest of the rain should be done the first part of Saturday. Many locations may stay dry on Sunday with temperatures near 60°.
The weather does not change much next week is that storm system will fall apart but it leaves behind a big upper level cool pool once again, with many instability showers each day for next week with the temperatures running on the cool side in the 50s.
