A Wind Chill Advisory will be in effect during the overnight hours as frigid temperatures could cause frostbite in as little as 30 minutes.
The Advisory went effect at 9 p.m. Sunday night and will last through 9 a.m. Monday morning, according to the National Weather Service. McHenry, DeKalb, and LaSalle counties are all impacted by the Advisory, which comes as another blast of Arctic air is set to hit the region.
In Lake, Kane, DuPage, Kendall, Grundy, Will, and Kankakee counties, the Advisory will take effect at midnight, and will last through 9 a.m.
According to the NBC 5 Storm Team, wind chill values across the area could drop down as low as 25 degrees below zero in some locations, and the light of day won’t bring much relief, as high temperatures will only creep into the single digits. Wind chills are expected to remain 10 to 20 degrees below zero as the work week begins.
It will take several days for temperatures to rebound to more seasonal levels, as the mercury should rise back up to the upper 30’s by Friday.
