With periods of heavy rain already buffeting southwestern Connecticut early Tuesday, the National Weather Service continues to warn that flash flooding in the region remains possible.

The rain is expected to fall, off and on, throughout the day, but taper off later. The daytime high temperature is expected to be about 70 degrees with a northeast wind around 11 mph.

The flood watch remains in effect for the region through the afternoon.

As rain eases overnight, patchy fog may move into the region, the NWS says. The temperature is expected to dip to a low of about 59 degrees.

Tomorrow, there is still a chance of showers, with skies remaining cloudy and a daytime high of 65 degrees. The overnight low will be in the low-60s with an east wind between 8 and 11 mph.

On Thursday, showers remain a possibility. Skies will still be cloudy, with a high near 75. Showers -- again -- could fall Thursday night, the NWS says, with a low temperature of 65 degrees.

Friday will be mostly cloudy, with a high near 76 degrees, the weather service predicts.
