The National Weather Service is warning that a fast-moving line of showers and thunderstorms today could produce damaging winds — and even a tornado here and there.
With the leaves still on the trees and the wind blowing up to 45 miles per hour, the potential for tree damage — and power line outages — is even greater, the forecasters said, as the storms roll through the state from west to east from 4 p.m. to 9 p.m.
And then there’s the rain: Up to an inch could fall in an hour, producing ponds of water on the highway for the evening rush hour and possible flooding in urban and poor drainage areas, the forecasters said.
Western Massachusetts residents should keep a particularly close eye on the weather. The weather service has issued a tornado watch for Berkshire County and a severe thunderstorm warning.
Weather service radar showed a line of storms rolling into the area at 4 p.m. The weather service reported receiving reports of trees down in Richmond and Pittsfield.
Humidity levels will rise today, and dew points could reach into the mid-60s. Temperatures will crest in the upper 70s.
“Following the rain, Tuesday and Wednesday will both be nice days,’’ said William Babcock, weather service meteorologist.
Showers will persist into Tuesday morning but should diminish by around 7 a.m. Skies will begin partly sunny, and the state should see even more sun through the day. Temperatures will climb to around 70, according to the weather service. Conditions will remain clear overnight as temperatures drop into the 40s.
Wednesday will be sunny and seasonably cool, as temperatures settle in the low 60s. A northeast wind will develop through the day, bringing gusts up to 10 miles per hour. Some clouds will develop overnight, as temperatures fall into the 40s.
Thursday will begin partly sunny, and temperatures will crest in the low 60s. Rain could come late Thursday into Friday, and Friday will see cloudy conditions through the day.
The weekend could see improving conditions, with a drying trend likely. Saturday and Sunday should be sunny and dry, and temperatures will hover in the low 60s, according to the weather service.
