inches north of the I-74 corridor: however, the primary hazard
will be light freezing rain mixing with the snow across much of
central Illinois. While ice accumulations will be minimal, a thin
glaze of ice could create slippery conditions on untreated
surfaces.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Slow down and use caution while traveling. The latest road
conditions for Illinois can be obtained on the Internet at

Be prepared for slippery roads. Slow down and use caution while
