There will be one more fine spring day in southwestern Connecticut before things start taking a weather turn for the worse, according to the National Weather Service.

Today, however, will mirror yesterday's balmy conditions, with sunny skies and temperatures rising to a daytime high in the mid-70s. There will be a north wind 5 to 7 mph, becoming southeast in the afternoon.

Tonight should be mostly cloudy, with a low temperature about 50 degrees and a southeast wind 3 to 5 mph.

Tomorrow, as cloud cover increases across the region, the stage is set for what could be several stormy days. The temperature is expected to rise to a high in the low-70s.

By tomorrow night, showers are likely late and into early Friday as the temperature dips to about 60 degrees. Chance of overnight precipitation is 70 percent, the NWS says.

On Friday, more rain is forecast, with a daytime high temperature in the low-70s. Odds of precipitation are 80 percent.

Continuing rainfall is expected Friday night, with thunderstorms and downpours possible, the NWS warns in a "hazardous weather outlook." The overnight low temperature will be about 60 degrees.

Saturday may be a washout, with more rain and possible thunderstorms in the forecast. The daytime high temperature will be in the low-70s; odds of daytime precipitation are 80 percent. Nighttime should see an easing of the inclement conditions, but skies will remain cloudy and the temperature will hit a low of about 60 degrees.

The outlook for Sunday improves, according to the weather service, with partly sunny skies and temperatures in the 70s.
