Another night of below-freezing temperatures last night kept emergency cold weather shelters in Charlotte and Sarasota Counties open for a second consecutive night. With air temperatures near the freezing mark, patchy frost and wind chills down into the twenties, shelters opened to take care of people who had nowhere else to go to be warm. Tonight, though, the cold weather should ease considerably. A light wind and high humidity will help keep overnight temps in the low fifties to high forties. The low before dawn expected to be around forty-six degrees.
