The Memorial Day forecast for southwestern Connecticut includes a "hazardous weather outlook" from the National Weather Service.

The potential for severe thunderstorms, however, is greatest this afternoon, so many of the region's Memorial Day parades this morning are expected to step off as planned.

Skies this morning will be partly sunny, and the daytime high temperature is expected to rise to the upper-80s. There will be a west wind between 3 and 9 mph.

This afternoon, the NWS warns, there is a possibility of scattered -- and severe -- thunderstorms with heavy rain, hail and gusty winds. The overnight temperature will dip to a low of about 70 degrees.

Tomorrow, there is a chance of showers and thunderstorms, mainly after noon. Otherwise, skies will be partly sunny, with a high temperature in the low-80s. More unsettled conditions are possible tomorrow night, as clouds move and the temperature registers a low in the mid-60s.

On Wednesday, showers and thunderstorms are again possible, mainly before noon. It will be mostly cloudy, with temperatures in the mid-70s. Nighttime will be partly cloudy, with a low around 61.

The outlook for Thursday, according to the weather service, is sunny with temperatures in the mid-70s.
