Slippery travel conditions and poor visibility are expected this
morning in open areas as northwest winds gusting from 30 mph to
45 mph result in blowing and drifting snow. The lower visibility
may cause impacts to the morning commute. Winter Weather Advisories
are in effect for Vilas County, much of eastern WI, including the
Fox Valley, as well as Door County.

Wind chills of 20 to 30 below are expected this morning, and
again Tonight into Tuesday morning, leading to hazardous conditions
to anyone outdoors and unprotected from the cold. Cpld Weather Advisories
remain in effect for all areas, except for Door County where the Cold
Weather Advisory starts at 6 pm this evening.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday

Wind chills of 20 to 30 below will continue through mid morning on
Tuesday. Cold Weather Advisories remain in effect until 10 am Tuesday
for all areas.

Light snow late Tuesday night into Wednesday morning, especially
south of highway 29, could result in slippery conditions for the
Wednesday morning commute.

Another wave of bitter cold air is expected late this week into
next weekend. This bout of cold will even be more extreme than
what is occurring early this week, with daytime highs on Friday
and Saturday below zero for the majority of the area, and wind
chills as low as 30 below zero for the entire area.
