Humidity levels will remain low through the week, and rain is unlikely. Skies will remain mostly clear overnight, with evening temperatures in the 40s through the region.

“Daytime temperatures will be warmer, so temperatures won’t drop as low overnight,” Foley said. “We won’t see a frost advisory for the next several nights.”

Daytime temperatures Thursday will crest near 80 degrees. Rain is unlikely, and skies will remain sunny. Temperatures will dip into the mid-50s overnight, and conditions will remain clear.

Dry and mild weather will continue Friday, with a fair amount of sunshine and afternoon highs near 80. A sea breeze will develop, cooling temperatures a few degrees along the coast. A cold front will move across the region overnight, bringing a mixture of clouds and sun into the region.

Saturday will begin dry and partly sunny, with temperatures climbing into the mid-70s. Showers will develop late Saturday into Sunday, but a washout is not expected.

Sunday will see showers and mostly cloudy skies, with temperatures in the mid-70s. Thunder is not likely to accompany the weekend’s precipitation, according to the Weather Service.
