Warning. Today could be a washout.

On this first day of the weekend -- with an array of springtime events on the agenda -- the National Weather Service has issued a "Hazardous Weather Outlook," saying that storms this afternoon and evening could buffet southwestern Connecticut with a mix of heavy rain and winds.

The daytime high temperature is expected to rise to the upper-60s, and the threat of precipitation grows after 11 a.m. to 80 percent this afternoon, the NWS says. The unsettled conditions, in advance of approaching cold front, could trigger a few thunderstorms with gusty winds.

Showers and thunderstorms are also possible tonight, the NWS says, as the temperature dips to a low in the mid-50s. There will be a south wind 5 to 7 mph, becoming calm after midnight. Chance of nighttime precipitation is 60 percent.

Tomorrow -- Mother's Day -- will be cloudy in the morning, but skies will clear and the sun should emerge as temperatures rise to about 70 degrees. There will be a west wind 7 to 12 mph, increasing to 13 to 18 mph in the afternoon.

Tomorrow night should be mostly clear, with a low temperature about 40 degrees.

Monday will be mostly sunny, the NWS says, with a temperature in the low-60s. Night skies will be partly cloudy, with a low temperature about 40 degrees.

The outlook for Tuesday, according to the weather service, is sunny and temperatures in the 60s.
