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

.DAY ONE...Tonight

No hazardous weather is expected at this time.

.DAYS TWO THROUGH SEVEN...Sunday through Saturday

An intense spring storm system will bring strong gusty winds and
heavy precipitation to the area Sunday through Monday. The storm
will bring a heavy wet snow, with accumulations of 6 to 14 inches
north of a Marshfield to Wausaukee line. Snowfall amounts around
an inch or less are expected from the Fox Valley east to the
lake.

Behind the low pressure system, strong northwest winds of 20 to
30 mph with gusts around 45 mph are expected on Monday. The
combination of the heavy wet snow and strong winds may cause
sporadic tree damage and power outages.

Record high lake levels and gusty onshore winds could also lead
to lakeshore flooding on the Bay of Green Bay and the Lake
Michigan shoreline Sunday into Monday evening.

Hazardous conditions are expected to continue near streams and
rivers due to high water levels and fast flows from the next
round of rain or melting snow.

.SPOTTER INFORMATION STATEMENT...

Spotters are requested to report snowfall amounts, precipitation
totals over an inch and any flooding.
