Rain has been falling across southwestern Connecticut for several hours early this morning, and is expected to continue through early afternoon, according to the National Weather Service.

The daytime high temperature is expected to rise to about 50 degrees, accompanied by breezy conditions with an east wind 20 to 23 mph, later becoming south 7 to 10 mph.

Tonight, more rain is likely late and into early Friday. The low temperature will be in the upper-30s, with a west wind 7 to 10 mph becoming south.

Precipitation remains possible tomorrow, primarily before 10 a.m. Skies will be mostly cloudy, with a high near 45 and there will be a southwest wind 16 to 19 mph, later increasing to between 25 and 28 mph. Gusts could be as high as 43 mph. Tomorrow will be mostly cloudy, with a low temperature in the upper-20s.

Saturday should be partly sunny, with a high temperature near 40 degrees and a west wind between 17 and 20 mph. Nighttime will be partly cloudy and cold, with a low temperature falling to the upper-teens.

The outlook for Sunday, the weather service predicts, is mostly sunny and cold, with a high temperature reaching only the upper-20s.
