Update on Weekend Snow

While there is still quite a bit of variation in the models' forecast track of the oncoming area of low pressure this weekend, we are starting to get a slightly better idea of what's going to happen in terms of snow and wind on Saturday and Sunday. At left is the 60-hour forecast prog of the Canadian model, which I think gives the best compromise amongst all the model solutions at the moment. It depicts a surface low passing overhead or just to the south of the Stateline on Saturday evening. This track would leave Wisconsin in the heaviest band of snow. Around here, we'd probably see a mix of rain and snow on Saturday morning and early afternoon, changing to all snow by mid-afternoon. After getting about 2-4" of accumulation, a break from the snow is possible by evening with the low passing overhead, then some fluffy, light snow would wrap-around this low as it continues eastward late Saturday night and Sunday morning. Even though the snow would taper-off Sunday morning, powerful north to northwesterly winds would blow this snow around and bring us biting-cold wind chill values of 10-20 degrees below zero by Sunday morning. In fact, wind chill values could approach 30 below zero on Sunday night! We'll continue to watch this weather system for you and post more updates on here as more information comes in.  --TS
