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

.DAY ONE...Tonight

Scattered thunderstorms are possible through early evening, and
again overnight. A few of the evening storms could be strong and
produce hail to 1/2 inch in diameter and wind gusts to around 40
mph, mainly across central and east-central Wisconsin.

Runoff from snow melt will continue to cause high water levels and
strong flows on rivers and streams, along with low-land flooding.

.DAYS TWO THROUGH SEVEN...Sunday through Saturday

River flooding and strong flows will continue across much of
central and far northeast Wisconsin through the week. Potential
for even more extensive river flooding will increase later this
week and into next week as precipitation persists in the forecast.

Hazardous travel is possible late Sunday into Monday due to heavy
snow. Amounts are still uncertain, but significant accumulations
of 6 inches or more are possible across central and north-central
Wisconsin. Wind gusts up to 45 mph will create blowing and
drifting snow and possible power outages.

A few thunderstorms are possible Sunday. These storms are not
expected to be severe.

.SPOTTER INFORMATION STATEMENT...

Spotters are requested to report any hail or wind gusts over 40
mph to the National Weather Service in Green Bay.
