A winter weather advisory is in effect for McHenry County until noon Sunday.
Meteorologist Matt Friedlein said the National weather service expected 3 to 7 inches of snow to accumulate through Sunday afternoon, which would make travel conditions hazardous.
Brisk winds of 15 to 30 mph on Sunday could lead to blowing and drifting snow, which would reduce visibility, the weather service said.
A wind chill warning is set to be in effect from 6 p.m Sunday through noon Tuesday.
The weather service is forecasting a prolonged period of dangerously cold wind chills from Sunday night through Tuesday morning.
Wind chills are expected to be 30 below zero, with wind chills of 40 to 50 below zero expected late Sunday into Monday afternoon.
