Winter Storm Warning Issued for Southeast Wisconsin

The National Weather Service has issued a Winter Storm Warning for the majority of southeastern Wisconsin ahead of the area's first snow storm. The warning will go into effect Friday night at 9:00 PM and last through Saturday 3:00 PM. Dodge, Fond du Lac and Sheboygan Counties are under a Winter Weather Advisory.

Snow is expected to arrive in the metro around 9:00 PM Friday night with heavy snow moving in late Friday through Saturday morning before becoming more scattered in the late morning and afternoon of Saturday.

A widespread snow of 4 to 7" is likely in most locations. Our far northern spots may see lesser amounts in the order of 1 to 3".  However, snow will be widespread through the night. In addition, the latest data suggests a period of northeast wind Saturday morning, which will lead to the development of lake effect snow bands. These bands of snow may provide bursts of moderate to heavy snow which could lead to higher amounts from Milwaukee and points south. In those lake affected areas, snowfall amounts could be at 6-10". Otherwise, the heaviest amounts are still expected for the counties that border Illinois, in the range of 6-9".

Winds will be picking up as the storm winds down late Saturday morning from the north at 10 to 20 mph, with gusts possibly to 30 mph. That will lead to some blowing and drifting late. Wind chills will fall to the single digits by Saturday night into Sunday morning.

Please use extreme caution for travel Friday night and Saturday.
