Tonight: Lows in the middle 30s tonight with patchy frost possible. Tuesday: Mostly sunny and cool. Highs in the middle 50s. Lows near freezing Tuesday night with widespread frost likely.

Plan on a bright, breezy afternoon with temperatures in the upper 40s and lower 50s across southern New England. The actual high will be recorded as 59 degrees in Boston, but that was back at 2 AM!
