Lingering moderate to heavy snowfall over portions of eastern WI, with snow rates gradually decreasing southwest to northeast. Gusty winds lead to continued blowing & drifting snow through midday, gradually weakening through this afternoon. #wiwx #sewiwx
Blizzard conditions are ongoing due to blowing and drifting snow, with north-northwest gusts of 40-45 mph, reducing visibility to 1/4 mile or less across much of southern WI. Treacherous travel is expected through the morning given widespread wind-blown and snow-covered roads.
Already seen 4-9 inches fallen as of 1 AM, but an additional 6–10 inches are possible for east-central WI, 4–8 inches for southwest and south-central WI, and 3-5 inches for southeastern WI. Bands of moderate to heavy snow with 1/2-1 inch per hour are moving through southern WI early this morning and will continue into the early afternoon tapering in intensity from southwest to northeast throughout the afternoon.
Gusty north-northwest winds will combine with moderate to heavy snow to support blowing snow and reduced visibilities tonight through early this afternoon. Temps will continue to drop today and any wet roads after the snow end may refreeze tonight into Tuesday morning.
