Chicago First Alert Weather: Cloudy, breezy day CHICAGO (CBS) -- A strong fall flavor is in our weather today and tonight, with plenty of clouds, cool/chilly temperatures, and some lake effect sprinkles mainly along the Illinois-Indiana border. Winds will relax tonight and some areas inland could dip down into the mid-30s if skies have a chance to clear out which would mean some patchy frost is possible in those areas, according to CBS 2 Meteorologist Gerard Jebaily.
