Special Weather Statement issued February 23 at 9:19PM CST by NWS Green Bay WI

A brief period of light rain or freezing rain is expected across
far northern Wisconsin between 11 pm and 5 am. While air
temperatures may remain slightly above freezing in some areas,
roads, bridges and sidewalks are likely to drop below freezing.
Thus, any rain that develops may freeze on untreated surfaces,
leading to locally icy conditions overnight.

Those with travel plans across far northern Wisconsin tonight
should be prepared for icy spots and locally hazardous travel
conditions on untreated roads. Pedestrians should also use
caution, as sidewalks, driveways and parking lots may become
slick. The slippery conditions may linger into the Monday
morning commute.
