Another gloomy day of potential rain and storms is in store for southwestern Connecticut, according to the National Weather Service.

The rain, which could be heavy at times, has also prompted a flash flood watch for the rest of today in the NWS' "hazardous weather outlook."

Showers and thunderstorms are periodically possible throughout the day, with the greater threat after 1 p.m. Expect patchy fog in the morning and cloudy skies for the rest of the day as the temperature rises to a high of about 80 degrees. There will be a south wind 6 to 10 mph. Chance of daytime precipitation is 60 percent.

Tonight, there is a lessened threat of storms -- about 30 percent -- but some of the outbreaks could be severe, the NWS says. Skies will be cloudy and the temperature will dip to a low in the upper-60s.

Tomorrow, there is a 20 percent chance of precipitation as skies remain cloudy, with a high temperature in the mid-80s. Nighttime brings a continued 20 percent chance of precipitation, along with patchy fog, as the temperature dips to a low in the upper-60s.

Independence Day fireworks on Thursday are under threat of isolated showers and thunderstorms after 1 p.m., the NWS says. Otherwise, skies will be partly sunny, with a high temperature in the mid-80s. Chance of daytime precipitation is 20 percent. There could be more isolated storms Thursday night as the temperature dips to a low of about 70 degrees.

Friday, however, may see a break in the storm cycle that has had the region in its grips for the last several days as skies are expected to be mostly sunny, with a daytime high temperature in the mid-80s. Nighttime should be mostly cloudy, with a low temperature around 70 degrees.

The outlook for Saturday, according to the weather service, is partly sunny, with temperatures in the 80s.
