Temperature readings today in southwestern Connecticut, struggling back from overnight lows in the frigid single digits, will not rise above the freezing mark, according to the National Weather Service.

Under mostly cloudy skies, the daytime high temperature will rise only into the upper-20s, and wind-chill values will feel as though it is minus-3 degrees, the NWS says. The west wind will register between 9 and 13 mph.

Tonight also will be mostly cloudy, but the overnight low -- in the low-20s -- will not plummet as far as last night. There will be a west wind between 9 and 13 mph.

Tomorrow will begin under mostly cloudy skies, then gradually becoming sunny, with a high near 40 degrees. Clouds move in again tomorrow night, as the temperature falls to a low in the upper-20s.

Friday should be mostly cloudy, with a high near 45 degrees, the NWS says. The nighttime low temperature is expected to be around 35 degrees.

Saturday will be partly sunny, the weather service predicts, with a high near 50 degrees.
