A cool weekend expected as summer exits the stage

By Globe Staff

A cool weekend is ahead as summer takes a bow and exits the stage.

Summer officially ends at 10:49 a.m. Saturday. Fittingly, a cold front will be approaching from the west, the National Weather Service.

Highs on Saturday ranging into the high 70s will will drop to the high 40s to mid-50s on Saturday night, then rebound Sunday to the high 60s to low 70s.

On Saturday, showers, thunderstorms, or both may develop during the late afternoon and early evening in the western part of the region and roll east during the evening and overnight, but most areas will remain dry, forecasters from the service’s Taunton office said on their website.

Today temperatures are expected to be in the low to mid-70s, with temperatures in the mid- to high 60s along the coast.

Sunshine will filter through high clouds, forecasters said, except over the Cape and islands, where there’s a slight chance of precipitation late in the afternoon into the evening. Tonight showers over the Cape and islands will end. Areas of fog are expected, and low temperatures are expected to drop to the upper 40s to mid-50s.

For the first half of next week, high pressure will build over New England with cooler weather, as daytime highs mostly stay in the 60s, the forecasters said.
