Extreme cold arrives Thursday night and lasts through the weekend

Dangerous cold is on the way. An Extreme Cold Warning has been issued for all of southeast Wisconsin from midnight Thursday night through 1 PM on Friday. Another Extreme Cold Warning might be issued for Friday afternoon through Saturday morning or if wind chills look a little warmer then a Cold Weather Advisory could be issued. 

This is the first Extreme Cold Warning in a year in Milwaukee since a round of cold air right around this time last year. Highs on Thursday will stay in the teens. The official "high" for Friday might go down as the temp right at midnight which would be around 0 but the afternoon highs on Friday will stay below-zero. Saturday the high temp gets above-zero then we see a bit of a better chance for teens to return by the beginning of next week. 

Part of the reason the wind chills will be so dangerous is how strong the wind will be Thursday, Thursday night and Friday. Expects gusts over those 48 hours to range from 15-35 mph. Then on Saturday the wind speed becomes lighter from 5-15 mph which will have an impact on wind chills.

Even though they aren't labeled as "dangerous", wind chills on Thursday will still be cold to -10 in the morning and not much better than 0 in the afternoon. Wind chills will be at their most extreme level Friday morning when they could drop to -40 and doesn't get much better than -25 during the day. 

Saturday morning should be slightly better with the lighter wind and wind chills to -30 in the morning but staying below-zero all day. We probably don't see wind chills get above-zero until Sunday afternoon.
