Rain and scattered thunderstorms are likely this cloudy day in southwestern Connecticut, the National Weather Service warns.

There is an 80 percent chance of daytime precipitation, the NWS says, and some of the storms could trigger gusty winds and downpours. In turn, that could unleash flash flooding, the NWS says, which has issued a flash-flood watch from 6 a.m. to 6 p.m.

The daytime high temperature will rise to the mid-70s, as cloud clover remains in place.

The odds of stormy weather slacks off tonight, with a 30 percent chance of precipitation mainly before 9 p.m. The overnight low temperature will be about 60 degrees.

Skies are expected to clear tomorrow, however, for a stretch of nice weather that should last through the weekend.

Tomorrow, skies will be sunny and the high temperature will be in the upper-70s. Nighttime will be mostly clear, with a low temperature in the mid-50s.

Thursday also will be sunny, with a high temperature in the upper-70s. Overnight skies are expected to remain clear, with the temperature dipping to a low of about 60 degrees.

Continuing the pleasant-weather cycle, bright skies are forecast Friday, with a high temperature about 80 degrees. Nighttime will be clear with a low of about 60 degrees.

The outlook for Saturday, according to the weather service, is sunny and temperatures reaching about 80 degrees.
