Snow is falling across southeast Wisconsin Thursday morning. Road conditions have gradually gotten worse and will continue to do so. See the updated road conditions in the image below. School closings started rolling in Wednesday afternoon. You can see all of those here.
A winter storm warning was issued Wednesday afternoon and goes into effect at 9 AM Thursday morning lasting all day Friday and ending Saturday morning. It may not be actively snowing during this entire time but the blowing snow and bitter cold justify the warning.
The latest snow forecast is in. And while snow totals may not be super impressive for Wisconsin standards, it's the dangerous wind that makes the snow worse. 2-4" of snow is expected in southern counties with 4-7" in northern counties. Most of this snow will fall during the day on Thursday through about midnight. An additional inch or two of snow is possible with lingering snow showers on Friday.
Winter impacts with this winter storm are pretty significant. Notice how the snow itself is not the biggest threat. The wind, cold and impact of the blowing snow on the roads is really the big problem.
The expected wind gusts have not changed much with wind gusts ramping up Thursday afternoon and evening to 30 mph. Wind gusts Thursday night through most of Friday could be as strong as 50 mph leading to whiteout conditions in open fields and rural areas. The wind stays very strong on Saturday with blowing snow still an issue.
The bitter cold and dangerous wind chills haven't changed either. Wind chills will drop below-zero by Thursday afternoon with wind chills as cold as -35* Friday morning. They don't get warmer than -20 during the day Friday with wind chills in the -30 to -15 range on Friday and -20 to 0 range on Christmas Sunday.
