It may seem more like winter than the just-hatched season of spring in southwestern Connecticut over the next couple of days, as the National Weather Service predicts rain, snow and sleet will buffet the region.

Rain is expected to start fall later today and continue into nighttime, with a daytime high of about 39 degrees.

Overnight, the rain is likely to start mixing with snow and sleet, according to the NWS as the temperature falls to about 30 degrees. The wind will pick up from the east at between 11 and 14 mph.

There could be new accumulations of snow and sleet from 1 to 3 inches.

Rain and snow is likely to continue until midday tomorrow, then changing to rain as temperatures rise to the low-40s. The day will be cloudy with a north wind around 16 mph. The precipitation will clear out by nighttime, but the temperature will fall to about 27 degrees.

Friday should be sunny, with a high near 40 degrees, the weather service predicts.
