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

.DAY ONE...This Afternoon and Tonight

Isolated thunderstorms are possible during the late afternoon and
evening hours, mainly over central and east-central Wisconsin. The
risk for severe storms will be limited, but a severe storm or two
with large hail and isolated damaging wind gusts cannot be ruled
out.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

A significant severe weather event is looking more likely Wednesday
afternoon into Wednesday night. Any of the thunderstorms could be
severe and produce damaging winds and large hail. A tornado or two
will also be possible, especially from central Wisconsin into the
southern Fox Valley. Torrential rainfall is also likely, and may
lead to flooding.

Humid conditions are also likely through Wednesday. The heat
index could reach the lower to middle 90s across central Wisconsin
and the southern Fox Valley. The combination of heat and humidity
will result in an elevated risk of heat related illness, especially
for individuals in poor health.

There is also a threat of thunderstorms on Saturday, though it is
too early to determine if severe weather will occur.

.SPOTTER INFORMATION STATEMENT...

Formal spotter activation is not expected to be necessary this
afternoon or tonight, but spotters should report any hail or wind
gusts over 40 mph. Spotter activation will likely be needed
Wednesday afternoon and evening.
