Residents in northeast Wisconsin, including areas such as Vilas, Oneida, and Door counties, should prepare for the possibility of severe weather on Thursday. The main risks include damaging winds, large hail, and localized flooding due to heavy rainfall. Mariners on Lake Michigan and Green Bay waters are advised to monitor conditions closely, as storms could create hazardous conditions. While the probability of widespread hazardous weather is low for Wednesday night, Thursday's storms could bring significant impacts to the region.
