Southeast Wisconsin weather: Dangerously cold wind chills, before weekend 'warm up'

Another bitterly cold start Friday, with lows below zero and wind chills -30° to -20°. Despite sunny skies, temperatures struggle to climb, with highs peaking near 10° in the afternoon. Wind chills remain at or below zero with winds out of the northwest at 10 mph. Temperatures fall into the low single digits this evening before southwest winds start to bring warmer temperatures to the area. We'll climb back up to 10° just after midnight and won't stop there as temperatures climb into the low to mid 30s by Saturday afternoon. Winds will be gusty at times Saturday and out of the southwest 15-20 mph, with gusts near 30 mph. Clouds push in for the afternoon and evening.
