Even though a large tropical storm taking today shape off the nation's southeastern coast is not expected to affect southwestern Connecticut, the Memorial Day holiday weekend's forecast is far from storm free.

The National Weather Service predicts there is at least a 30 percent chance of precipitation -- showers and isolated thunderstorms -- every day this weekend and early next week.

Today, showers and thunderstorms are possible, mainly between 2 and 3 p.m., the NWS says. After morning clouds and fog dissipate, skies are expected to become partly sunny as temperatures rise to the low-80s. There will be a west wind between 6 and 9 mph.

There is a slight chance of showers and thunderstorms before midnight, as skies turn cloudy and the temperature dips to a low of about 60 degrees.

Tomorrow, showers and thunderstorms are possible again, mainly after noon. Skies will be mostly cloudy, with a high temperature in the mid-70s. Nighttime brings the possibility of more showers and thunderstorms, mainly before 11 p.m. It will be mostly cloudy, with a low temperature in the low-60s, the NWS says.

On Monday -- Memorial Day -- there is a chance of showers and thunderstorms again. Otherwise, skies will be partly sunny, with a high temperature in the upper-70s. Nighttime is expected to be mostly cloudy, with a low temperature in the mid-60s.

The outlook for Tuesday, according to the weather service, is for more unsettled conditions after noon, partly sunny and temperatures in the mid-70s.
