Even though clouds will cover skies across southwestern Connecticut for much of today, the high temperature is expected to be the warmest of the year, reaching into the upper-60s.

The National Weather Service says there also could be early patches of fog and a south wind between 9 and 15 mph, with gusts as high as 25 mph.

Tomorrow more showers are likely, mainly after 4 p.m. Skies will be cloudy again, but the day will not be as warm, with the high in the mid-50s. Rain is also possible tomorrow night, with a low of about 44 degrees.

Rain is also in the forecast for Wednesday, skies will be cloudy and the daytime high temperature will be about 48 degrees. There is more rain possible at night, and the temperature will fall to a low of about 40 degrees.

Thursday should be partly sunny, with a high near 59, the weather service predicts.
