heavy snow will pass through over the next 3-6 hours dropping a quick 1-3" of snow across northwest WI. Around one inch into northern WI and upper Michigan. Expect slippery road conditions overnight and tomorrow morning, perhaps some flurries lingering across the north.
snow continues to spread east. Around 1-2" by morning. Slippery roads possible overnight. Wishing everyone safe travels!
It will approach from the west, perhaps rather quickly later tonight. Be prepared for slippery roads overnight and possibly for the Monday morning commute.
2-4" reported across far southeast WI. The heaviest snows are moving out. Cannot rule out light snow showers through up through midnight.
Znow is moving back in across southeast WI. Models today continue to back track and lower snow amounts run after run. Rare to see such a huge downtrend. AS IT STANDS RIGHT NOW you will be lucky to get an additional 2-4". I don't believe the 8-12" Will materalize. Windy conditions continue with gusts near 35 MPH in the east (perhaps over 40 MPH along the lakeshore). -JP
Confidence is still low with this event and some models are further east with the snow tonight. Peak time for accumulation is between 4PM and Midnight tonight. 4-8" in portions of southeast WI.
Relatively quiet today with the peak freezing rain period done with. Cannot rule out light freezing drizzle in southern WI. Wouldn't be suprised if dry air cut that off entirely. Heavy snow develops further south into southeast WI after 4PM tonight ending around midnight. Models vary on how far west this next round will go...no farther than Oshkosh - Dubuque line is my expectation. Additional 4-8".
slippery stretches all over southern and eastern WI, ice covered on 94 between Madison and Janesville and 41 south of Fond du lac. I'm guessing light snow has compacted into black ice north of Green Bay. Roads should improve today as plow crews get after it during the warmest part of the day.
dry air is pushing in on the western edge. Seeing many 1 and 2" reports...definitely some spots higher than that by now. Freezing rain is/was occurring in the forecasted zone between NE IA, WI/IL border, and southern WI (highest amts on elevated surfaces). Doesn't appear to be significant yet. Heaviest precip will move off early Sat AM replaced by light freezing drizzle or mist throughout the morning ahead.

Heavy snow coming down now Platteville to Madison to Watertown. Up to 2" reported southwest of Madison seems on target. Dry air holding tight in Green Bay (NE WI). Wintry mix, freezing rain, and rain in the far south...could see freezing rain down near the WI/IL border but temps near/above freezing still in Janesville. Heavy precipitation tonight, lighter tomorrow into the mid-day hours. Round #2 Sat PM.
