I've had a couple of calls from people wondering why we even mention wind chill factors in the first place. We report the temperature. I'd have to say no. As I'm sure you know, a temperature in a calm wind doesn't feel the same as a temperature when it's windy. As winds pick up, body heat is lost much more quickly.
Frostbite can set in much sooner.
The wind chill index is designed to reflect that danger. I think meteorologists would be doing a disservice if we were to ignore wind chill readings altogether. This cold spell should ease a bit by the weekend. What's missing from the forecast is that Christmas snow that many of us would like to see. In Milwaukee, just trace amounts are on the ground now . . .
