This Hazardous Weather Outlook is for north-central and northeast
Wisconsin.
.DAY ONE...Today and Tonight
Moderate snow will diminish through sunrise over central and
east-central WI. Additional accumulations of 1 to 4 inches are
expected, with the highest amounts over east-central WI. Snow
will wrap up across the entire region by mid morning. North winds
gusting to 30 to 35 mph this morning will combine with the
freshly fallen snow to result in patchy blowing and drifting snow
in open areas, especially from the Fox Valley to the lakeshore.
If traveling this morning, allow extra time as many roads may
still be snow covered. Untreated east-to-west oriented secondary
roads along with open areas susceptible to drifting snow will
especially be a concern this morning.
Locations that receive heavy snow in central and east central
Wisconsin could also experience sporadic tree damage and power
outages, especially as winds increase this morning.
.DAYS TWO THROUGH SEVEN...Thursday through Tuesday
Wind chills could drop to 10 below to 30 below zero Friday night
into Saturday morning, and again Saturday night into Sunday morning.
Cold weather headlines will likely be needed this weekend.
.SPOTTER INFORMATION STATEMENT...
Spotters are requested to forward snowfall measurements and road
conditions to the National Weather Service in Green Bay.
