...SCATTERED THUNDERSTORMS EXPECTED ACROSS NORTH-CENTRAL WISCONSIN
THIS AFTERNOON...

Look for scattered thunderstorms across north-central Wisconsin
during the afternoon hours. The strongest storms will be capable
of producing gusty winds to 40 mph, small hail, and torrential
rainfall. The storms will be moving very slowly, generally east at
around 5 mph. Therefore, repeated rainfall or slow storm movement
could lead to minor flooding.
