As the flooding threat continues in other parts of the state today, the National Weather Service warns that more heavy rainfall later in the week could trigger more.

Lower Fairfield County generally escaped the severe flooding that inundated the upper Housatonic River and lower Naugatuck River valleys yesterday, with only scattered incidents where local rivers and streams flowed over their banks, closing roads and flooding basements.

But heavy rain from Thursday into Friday could change that, the NWS warns.

Meanwhile, skies today in southwestern Connecticut should be sunny with a daytime high temperature in the mid-40s. There will be a north wind 7 to 11 mph becoming east.

Tonight will be partly cloudy, with the temperature falling to a low around 28.

Clouds will increase Wednesday, and the high temperature will be about 40, the NWS predicts. There will be an east wind between 13 and 17 mph. There is a chance of rain overnight, with a low of about 32 degrees.

Thursday will be rainy, with a high temperature in the mid-40s. A wind from the east will register between 15 and 22 mph, with gusts as high as 34 mph.

Heavy rain is forecast overnight, with the precipitation registering between 1 and 2 inches possible.

And the threat of flooding continues Friday as rain is expected to continue falling until early afternoon, according to the weather service.
