Forecast: Thunderstorms to Arrive by Afternoon

Thunderstorms are expected to sweep through the lower Westchester area this afternoon, according to the National Weather Service.

Local residents awoke Monday to a heavy cloud cover and a reprieve from the stifling heat wave that kept air conditioners blasting over the weekend.

Thunderstorms are slated to roll through Port Chester and surrounding towns beginning at about 4 p.m., bringing sporadic rain. Temperatures will remain in the mid- to high-70s, according to the weather service.

Although temperatures have dropped, the humidity hasn't -- the humidity gauge will begin climbing this afternoon, peaking at 90 percent humidity by the evening.
