Today should be sunny and relatively warm, one of the nicest days of spring so far. But enjoy, because the National Weather Service predicts southwestern Connecticut then will be in for several days of April showers.

Skies will be clear today, however, with the daytime high temperature rising to the mid-50s. It will be breezy, with a west wind between 16 and 20 mph.

Rain moves in overnight, starting to fall early Monday as the temperature falls to a low of about 40 degrees.

The rain is expected to keep falling Monday morning until about 9 a.m. Skies will be cloudy, but the temperature should rise to a balmy 56 degrees, the NWS says. The south wind will be between 15 and 18 mph.

Showers are also likely Monday night, and there's even the chance of a thunderstorm. The low temperature overnight will fall only to the high-40s. Breezy conditions will also prevail, with a south wind between 16 and 25 mph.

More rain and possible thunderstorms are likely Tuesday, according to the NWS. The high temperature will be in the low-50s. The wind from the west will be gusting up to 25 mph.

The precipitation should start clearing out by Tuesday night, and Wednesday should be mostly sunny, the weather service predicts.
