A Cool Down Coming...
Another mid-summer-like day just wrapped up here in Southern New England...highs reached the mid 80s once again and with much cooler air on our doorstep, it's quite possible this was the warmest day until next year! Normally, saying that would make me very depressed but I'm actually very excited for some invigorating air.
As these two airmasses collide over New England, showers and some thunderstorms will be likely at times through tomorrow evening. In fact, although isolated, a few potent cells have bubbled up this evening. But the real action won't arrive until tomorrow afternoon when a band of rain, aided by a wave of low pressure riding up the stalled front focuses a period of rain with embedded thunder over us for a few hours right before the chillier air arrives. Once the wave passes, in the evening, the gates will open for that chilly air to come cruising in and by Friday morning lows will be in the 40s!
This happens to be our last weekend of Summer before the equinox yet daytime highs hold in the 60s and more shockingly the overnight lows will be around 40! No worries for frost just yet though. It won't be perfectly sunny over the weekend but pretty close...sky cover will feature some cirrus on Saturday and some puffy cumulus on Sunday.
BTW, if this early season cool weather outbreak is premature for you, 70s and maybe even 80 make a return next week.
