Did you just set down that shovel?

You may want to pick up a blanket.

The snow may have passed, but now McHenry County must brace for extremely cold temperatures moving this way.

The National Weather Service in Chicago at 3 p.m. Thursday issued a Wind Chill Advisory for McHenry County starting at 9 p.m. tonight (Thursday, Jan. 2) and continuing through 10 a.m. Friday.

Other counties included in the advisory are Boone, Kane, Lake, DeKalb, LaSalle, Kendall, Ogle, Grundy and Livingston. 

The cold temps will arrive late this evening, and could drop to -8 to -18 degrees, the NWS says. Wind chill values will bring those numbers to 15 to 25 degrees below zero. 

A wind chill advisory means winds will combine with very cold air to generate low wind chill temperatures. The resulting conditions could lead to frost bite and hypothermia if precautions are not taken, according to the NWS. 

Those folks who must venture outdoors should be certain to wear a warm winter coat, hat and gloves for protection, according to the NSW.
