The National Weather Service has instituted a wind chill advisory that is in effect until noon Friday, due to arctic weather sliding into the area.

The combination of morning temperatures in the single digits and the brisk west wind will push wind chill readings to between 15 and 25 degrees below zero, according to the NWS advisory. 

Frost bite and hypothermia could occur if precautions are not taken when you are outdoors. 

This is the kind of cold that sometimes leads to school and business closings. Check out the closings list from WISN12 above, or click here for WISN closings and here for the TMJ4 closings.

As of 5:45 a.m., there were no Waukesha County closings listed on either site. If you learn of anything, please add it in the comments section.
