A rainy day -- and possible downpours this afternoon -- is forecast today for southwestern Connecticut, which could trigger some coastal flooding during the later high tide.

The rain is expected to start falling after 8 a.m., the National Weather Service says, and may cause patchy foggy to settle in parts of the region. The high temperature for the day is expected to reach into the low-60s, with east winds between 9 and 17 mph. New rainfall amounts could be at least 1 and 2 inches.

The heavy rain could cause some coastal flooding in the area at the time of high tide, roughly 4:45 p.m. today.

Showers should continue tonight, before easing early Thursday. There will be patchy fog as the temperature dips to the mid-50s, with an east wind between 9 and 15 mph.

Tomorrow will be partly sunny, with a high near 68 degrees, the NWS says. It will be breezy, with a southwest wind between 15 and 20 mph. Tomorrow night will be partly cloudy, with a low around 49 degrees and a southwest wind between 11 and 15 mph, with gusts as high as 25 mph.

Friday is expected to be mostly sunny, with a high temperature is the low-60s.

And, Saturday, the weather service predicts, will also be mostly sunny, with a high near 59 degrees.
