Special Weather Statement
In light of the 4 to 8 inches of fluffy snow that fell over the area
on Saturday, northwest winds gusting from 20 to 25 mph overnight will
result in some blowing and drifting snow on area roadways. Many
roads are already snow covered and hazardous, especially in rural
areas. Given that wind chills will fall to colder than 20 below zero
overnight, getting stuck while traveling will be especially
dangerous. If you must travel tonight, leave plenty of distance
between vehicles, make sure you have an emergency kit with you, and
notify someone of your travel plans and expected arrival time.

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

surfaces.
