Rain, Sleet, Snow: But Where?

Location. Location. Location.  It matters!  A wintry system headed toward the Stateline overnight and Thursday will bring rain, freezing rain, sleet, and snow.  However, not all of us will see all of these different types of precipitation.

A Winter Storm Warning takes effect in Rock & Walworth County at 6am Thursday and last through Thursday night.  A Winter Weather Advisory takes effect in Green County at 6pm Wednesday and lasts through 6pm Thursday.  A Winter Storm Watch is in effect for McHenry County for Thursday.

Areas under a warning or advisory have the greatest potential for accumulating snow and accumulating ice, especially the further north you go.  The bulk of the precipitation will begin after midnight.  With temperatures hovering a couple of degrees below freezing, sleet and freezing rain will be a concern in Wisconsin.  During the day Thursday, a good 2 to 4 inches of snow is possible in Wisconsin.  Localized 5 or 6 inch amounts are not out of the question.

For Rockford and most of northern Illinois, precipitation is likely to fall in the form of rain.  Some sleet/freezing rain is possible at the onset of precipitation overnight.  However, rain is expected through much of Thursday morning through about the noon hour.  Rain will quickly change to snow afternoon.  A brief period of heavy snow is possible, with perhaps an inch or two in metro Rockford.  Snow accumulations to the south and southwest of Rockford will be very minimal (dusting to half an inch).  The Thursday evening commute may prove to be a bit difficult.
