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

.DAY ONE...Today and Tonight

There is chance for thunderstorms today into this evening, mainly
over eastern Wisconsin. The storms are not expected to be severe,
but a few of the storms could produce gusty winds and heavy rain.

Hazardous travel conditions are possible late tonight into early
Thursday over far north-central Wisconsin. Temperatures are
expected to drop to around freezing while precipitation occurs
tonight and early Thursday. That could result in the
precipitation falling as sleet or freezing rain at times. Be sure
to closely monitor later forecasts, since even a small departure
from the current temperature forecast could have a significant
impact on the amount of wintry precipitation that occurs.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

The rains from today into early Thursday may cause some rivers
and streams to rise to near or above flood stage during the latter
portion of the work week.

Another system is forecast to impact the region Saturday night
through Monday. Additional heavy rains are possible, primarily
over eastern Wisconsin. This could raise river and stream levels
once again to near or above flood stage. Light snow will be
possible across north-central Wisconsin Sunday night. It is too
early to determine potential snow accumulations.

.SPOTTER INFORMATION STATEMENT...

Spotters are requested to forward any reports of freezing rain or
sleet to the National Weather Service. Any reports of hail from
thunderstorms in eastern Wisconsin, or street flooding due to
heavy rain would also be appreciated.

for street and possible river flooding, as some areas may receive 1
to 2 inches of rainfall.
