A drenching thunderstorm swept through the Boston area this afternoon.

The National Weather Service issued a special weather statement at 3:22 p.m. reporting that a line of storms, extending from Watertown to Marblehead, was moving southeast at 25 miles per hour. The storms were producing small hail, frequent cloud-to-ground lightning, and torrential rainfall as they moved.

The weather service reported at 3:43 p.m. that the strongest storms had weakened and moved out of the Boston area, heading over the South Shore toward the ocean.

But another round of storms could appear, forecasters cautioned. A severe thunderstorm watch remains in effect for the entire state until 8 p.m. The weather service reported that storms may appear most frequently after 5 p.m. in the eastern part of the state.

The day will otherwise be partly sunny and humid, getting as hot as 91. Temperatures tonight will be in the low to mid-60s.

Wednesday will be sunny with temperatures in the high 70s to low 80s. Meteorologist Alan Dunham said a “nice northwest wind with some gust to it” and lowering humidity will make for a “gorgeous” day.

But the sun will disappear for the rest of the week.

“There’s a frontal system hanging around the region, so there will be a chance for showers and thunderstorms each day,” Dunham said.
