This Hazardous Weather Outlook is for north-central and northeast
Wisconsin.

.DAY ONE...Today and Tonight

Untreated roads could become slippery today due to occasional
light snow and flurries. Some freezing drizzle is possible in
central and east-central Wisconsin late today as the snow tapers
off and ends.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday

There is an increasing chance for light snow across east-central
Wisconsin Friday night into Saturday morning. Even though most
areas will see accumulations under an inch, this may be enough to
create slippery road conditions.

Lake effect snow showers may create hazardous travel conditions
across the far north, especially Vilas County into early next
week.

Arctic air is forecast to overspread the region this weekend. Wind
chill readings Saturday night into Sunday morning will range from
10 to 22 below zero.

Another system may bring accumulating snow to the region Monday
night into Tuesday. It is too early to determine snow amounts at
this time.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today or tonight.
