Another Cold Night Ahead

Update: Frost Advisory now issued for Stephenson and Jo Daviess counties.  To be safe, bring in or cover anything that may be sensitive to the cold.


High pressure is settling down into the Midwest Tuesday evening helping to get rid of the cloud cover we experienced earlier in the day.  But it's also pulling down a much cooler air mass.

With overnight lows expected to drop into the middle to upper 30's, a Frost Advisory has been issued for Green, Rock and Walworth counties in southern Wisconsin.  As well as for Winnebago, Boone and McHenry counties in northern Illinois.

Overnight temperatures are expected to drop into the middle to upper 30's by daybreak Wednesday.  With the clearing sky and calm wind, patchy frost is possible.  Bring in or cover any plants that are sensitive to the cold.
