A "Severe Thunderstorm Watch" has been issued for southwestern Connecticut this evening and later tonight by the National Weather Service.

A line of strong thunderstorms is heading toward the region from New York and Pennsylvania, the weather service warned as of 4 p.m., and is expected to arrive in this area between 7 and 8 p.m.

The storms could trigger heavy rain, dangerous lightning strikes, strong winds and even hail. They have already caused wind damage to the west, and are not expected to weaken as they sweep across the region.

Some of the storms could linger in the area until midnight, the NWS says.

Rain could be torrential, falling at 1 to 2 inches an hour, which could trigger flash flooding.

Winds could gust up to as high as 60 mph, and there is the possibility that isolated tornadoes could be generated.

And some of the hail could be up to an inch in diameter.

Tomorrow, more showers are possible after 10 a.m. Skies will be cloudy and the high temperature will rise to the low-90s. Some of the afternoon storms could also be severe, the NWS says.

There remains a slight chance of showers and thunderstorms tomorrow night, and the low temperature will be about 70 degrees.

On Saturday, skies will be cloudy and there again is a chance of showers and thunderstorms, mainly after noon. The high temperature will be in the mid-80s. More unsettled weather is possible Saturday night, as the temperature dips to about 70 degrees.

The outlook for Sunday, according to the weather service, is mostly sunny and temperatures in the low-80s.
