How about that temperature swing today? Taunton went from 44 to 83 today, Martha's Vineyard started at 42 this morning, and topped off at 80, and many other towns had 35+ degree swings. That is a characteristic of a dry air mass, as it cools efficiently at night and warms up fast during the day. Also, to help us out, there was no strong onshore breeze at the coast, so overall, it was a more comfortable beach day.
What many consider near perfect weather, comes to an end tonight.
Thin clouds this evening become thicker overnight as a complex of showers and thunderstorm approach Southern New England. We won't see any showers until well after midnight, but a few of those showers could grace us by the pre-dawn hours Monday. Clouds limit the sun at times Monday, and occasionally, a shower or thunderstorm rumbles through. Humidity also increases as dew points run in the low to mid 60s by late afternoon.
Tuesday and Wednesday feature even higher humidity, and a few more showers and storms. The lower threat of rain is Tuesday (30%) with more breaks of sun and highs in the mid 80s. The higher chance of storms is Wednesday afternoon and Wednesday evening (60%).
Behind the Wednesday PM front that brings in storms, we'll dry out for the end of the week, although a pop-up shower or storm is still possible Thursday afternoon. Friday looks dry.
So what about Labor Day Weekend? I know, I know, it's far out, but the early indications are we start dry and cool Saturday (mid to upper 70s), reach the 80s on Sunday, and well into the 80s on Monday (maybe 90 if a front near New England stays well north of us).
While August finishes in the city of Boston with no 90 degree days (last time in 2008), September may have a day or two that takes a run at 90 in it's first week. Summer's not giving up yet!
