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

.DAY ONE...Tonight

Runoff from snow melt will continue to cause high water levels
and fast flows on rivers and streams.

.DAYS TWO THROUGH SEVEN...Wednesday through Tuesday

The combination of gusty winds, low relative humidity, and warm
temperatures will create elevated fire weather concerns through
at least Thursday. A Fire Weather Watch has been posted along and
south of a line from Marshfield to Green Bay.

Flow rates and levels on streams and rivers in northern Wisconsin
will continue to increase as unseasonably warm temperatures
result in a significant melting of the snowpack. Some rivers will
reach or have already exceeded minor flood stage.

Most rivers in central and east-central Wisconsin are expected to
slowly recede this week. The exception will be large rivers with
headwaters to the north, including the Wisconsin, Wolf and
Menominee. These rivers will remain high as the snowmelt from the
north flows downstream.

A few thunderstorms are possible Saturday afternoon and evening
as a low pressure system tracks through the western Great Lakes
region. These storms are not expected to be severe.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed tonight.
