Friday evening will be about as pleasant as New England gets in September.
Clear skies and light winds will allow temperatures to drop noticeably overnight — inland areas that cool efficiently could dip into the mid-40s, while coastal communities and Greater Boston should hold in the low to mid-50s. It will be a great night to sleep with the windows open.
Saturday looks equally beautiful. High pressure will keep skies sunny and winds calm through most of the day, with highs reaching the upper 70s across inland areas including Springfield and Worcester. Coastal communities, including Boston and Cape Cod, will be cooler — held in the low 70s by sea breezes off the water. Enjoy it while it lasts…
