A light southerly flow of air is pushing increasing warm and humid air into the region. Temperatures on the 4th peaked in the middle 80s around the Cape and we’ll be similarly warm today. Dew point values have also jumped considerably over the last 24 hours and are sitting near 70F…even creeping into the lower 70s at times.
Expect the very warm (buy mainly sunny other than some patchy shoreline fog in spots) and humid conditions to persist through the day today and into Saturday. In fact, humidity levels will continue to inch upward tonight and Saturday as dew point values climb into the lower 70s.
The warm and muggy conditions will come to an end tomorrow night as a cold front plow southward through New England. This boundary will cross over our area during the first half of Saturday night and is likely to be accompanied by some showers and thunderstorms. Right now, timing of this activity looks to be near or shortly after sundown.
Warm and much less humid conditions will take over on Sunday.
