Frost Advisory Chicago area-wide early Monday morning

A Frost Advisory for a potential killing frost/freezing temperatures is in effect for northern Illinois into northwest Indiana including all of the Chicago area early Monday morning. Clearing skies and diminishing winds will allow temperatures to drop out of the 40s into the 30s after midnight with readings falling into the lower 30s by sunrise, causing the likelihood of a widespread frost across our area.
