Wind chill advisory active into Monday


Temperatures across areas of the Midwestern U.S. have dropped more than 40 degrees in the past 24 hours due to a massive cold front sweeping across the region.

With the drop in temperatures expected to continue through Sunday night and breezy conditions from the northwest lingering, the National Weather Service will have every Wisconsin county under a wind chill advisory until noon Monday.

Wind chill advisories are issued by the NWS when the combination of cold air matches with wind, creating low feel-like temperatures. Wind chill values on Sunday night and Monday morning could drop as low as -35 in some areas of Wisconsin.

Temperatures that low can lead to frostbite on exposed skin in as little as 20 to 30 minutes.

This weekend has seen a wide range in temperatures. On Saturday afternoon, parts of Adams and Juneau Counties saw temperatures in the mid to upper 40s, with areas in the Wisconsin Northwoods seeing temperatures break freezing.

The progression of a Arctic cold front between Saturday night and Sunday afternoon precipitated a dramatic drop in temperatures. 24-hour temperature change contours indicated parts of Minnesota dropping more than 45 degrees in less than a day on Sunday, with mid-day temperature contours indicating most of central Wisconsin dropping nearly 30 degrees.

The cold air now in place over Wisconsin is expected to stay in place through the remaining days of December.

Forecast highs on Monday are anticipated near 1 with lows on Monday night expected near -12. High temperatures are expected to remain in the single digits above and below zero until Friday with slightly warmer air works back toward the state.
