An Ice Storm Warning remains in effect for most of northern Illinois, with the exception of Jo Daviess County which is under a Winter Weather Advisory.

A mixture of sleet and freezing rain has been falling over nearly all of northern Illinois and southern Wisconsin with already 0.2 inches of sleet accumulating here at the station.  Freezing rain has been mostly falling over our southern

counties of Lee and DeKalb, but now sleet is beginning to mix in.  Road conditions continue to deteriorate this evening and are reported by the lllinois Department of Transportation as mostly ice covered, especially across north-central and northwest Illinois.

Travel is not advised this evening as the mixture of sleet and freezing rain will transition over to mostly freezing rain after 9pm/10pm.  There will still be some areas of sleet and freezing rain through early Wednesday morning.

Most of the precipitation should be done by sunrise Wednesday, but untreated surfaces like sidewalks, parking lots, decks, secondary and side roads will most likely still be slick.
