This Hazardous Weather Outlook is for north-central and northeast
Wisconsin.
.DAY ONE...Tonight
Thunderstorm chances will increase overnight, especially across
northern Wisconsin. Some storms could produce large hail, strong
winds and locally heavy rain.
The intense rainfall rates could result in urban street flooding,
ponding of water on roads, and rises on streams and rivers.
.DAYS TWO THROUGH SEVEN...Saturday through Friday
Thunderstorms across northern Wisconsin will end Saturday
morning. Additional thunderstorms are possible at times again next
week, with strong or severe storms possible on Monday into Monday
night with damaging winds and large hail. It is too early to
determine the severe weather risk after Monday.
A multi-day period of dangerous heat is forecast from Saturday
through Monday. Low temperatures in the 70s will provide minimal
overnight relief to the heat and humidity. A Heat Advisory is in
effect beginning at noon on Saturday.
Increasing south winds and building waves will result in an
increased risk of rip currents along Lake Michigan beaches
Saturday morning through Monday morning. A Beach Hazards
Statement is in effect.
