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

.DAY ONE...Tonight

Runoff from snow melt and a recent rain will continue to
produce minor flooding along some rivers over central Wisconsin,
and slowly rising rivers over north central Wisconsin and
far northeast Wisconsin. These conditions will continue to
produce ice breakup or make ice conditions unstable on area
rivers, lakes, and reservoirs. Monitor local ice conditions and
consider securing and protecting equipment, and removing ice
shacks. Colder but closer to normal temperatures will be arriving
later this week.

.DAYS TWO THROUGH SEVEN...Thursday through Wednesday

A strong low pressure system will bring wintry precipitation to
the area from Thursday night into Saturday morning. This system
has the potential to bring several inches of accumulating snow,
along with some mixed freezing rain to north-central and
northeast Wisconsin. The best chance for heavy snow appears to be
north of a line from Wausaukee to Marshfield. Areas south of this
line have an increased chance for a wintry mix of snow, freezing
rain and rain. The exact track of the low will determine where
the swath of heavy snow will end up falling, therefore future
forecasts should be closely monitored.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed tonight.
