Light Snow Follows Extreme Cold Thursday Evening

A quick moving clipper system Thursday afternoon and evening will bring another round of light snow to northern Illinois and southern Wisconsin.  Moisture will remain limited with this system, but stronger forcing in the atmosphere and a very cold air mass will allow the snow to 'fluff' up to at least an inch or two, possibly three, by Friday morning.

Thursday morning will be dry, but cold.  Temperatures could be as low as -30 degrees by sunrise in some locations.  The wind isn't expected to be as strong as Wednesday morning but wind chills could fall close to -45 degrees by Thursday morning.  Cloud cover will thicken up during the day with light snow develop between 3pm-5pm Thursday.  Most of the snow should be done with by Friday morning.
