.LIGHT TO MODEST SOUTHERLY WINDS ARE ADVECTING VERY MOIST AIR ATOP
THE COLD LAKE SURFACE, RESULTING IN DENSE MARINE FOG ACROSS LAKE

IN RESPONSE. THERE IS FAIRLY HIGH PROBABILITY THAT GUSTS ACROSS THE

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

.DAY ONE...Today and 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 Tuesday

A strong low pressure system will bring wintry precipitation to
the area from Thursday night through Saturday. This system has the
potential to bring several inches of accumulating snow 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, sleet, and freezing 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 today or tonight.
