A cold front moving into the region this afternoon promises clearer, cleaner skies for southwestern Connecticut, but could trigger rain and thunderstorms, the National Weather Service warns.

The greatest risk of storms -- some of them severe -- is between noon and 5 p.m., the NWS says, while daytime high temperatures are expected to reach the mid-80s after the morning fog burns off.

There is a continued threat of rain and thunderstorms later tonight until about 10 p.m., the NWS says. Skies should clear overnight as the temperature dips to about 60 degrees.

Tomorrow should be sunny, with a high near 72 degrees. It will be breezy, with a west wind between 17 and 24 mph. It will be cooler tomorrow night, with temperatures in the low-50s.

The forecast for Friday and Saturday is promising: Both days are expected to be sunny with the high temperature in the mid-70s.
