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

.DAY ONE...Rest of the Afternoon and Tonight

Isolated thunderstorms will come to an end late this afternoon
or early this evening. Some of the stronger storms could produce
small hail, gusty winds to around 35 mph and brief heavy rain.

Late tonight, patchy fog may develop in spots that may restrict
visibilities for motorists.

Due to recent heavy rains, above normal river flows continue on
many area streams and rivers, especially downstream of hydro
plants. Boaters and fishermen should use caution due to fast
flows.

.DAYS TWO THROUGH SEVEN...Wednesday through Tuesday

Thunderstorms are expected Wednesday evening into Thursday
morning. There is a marginal risk of severe storms Wednesday
night, mainly southwest of a line from Rhinelander to Green Bay.
Large hail and damaging winds are expected to be the main severe
threats.

Another round of thunderstorms are forecast for Thursday afternoon
into Thursday night as a cold front slowly settles to the south.
There is a marginal risk of severe storms, mainly south of a line
from Marshfield to Green Bay. Large hail and damaging winds are
again the primary threats.

Thunderstorms are possible during the upcoming weekend into early
next week, primarily during the afternoon hours. It is too early
to determine whether any of these storms could become severe.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed tonight.
