Green Bay, Wis. – Residents across northeast Wisconsin should prepare for a late-evening round of thunderstorms, with the greatest risk for strong to severe storms now expected between 8 p.m. and midnight. While widespread severe weather is not anticipated, isolated storms could produce damaging wind gusts, large hail and heavy rainfall, especially north of Highway 29.
According to the National Weather Service in Green Bay, the highest chance for severe weather remains focused along and north of Highway 29, including areas near Rhinelander, Crandon, Iron Mountain, Antigo, Marinette and surrounding communities. Forecasters say the timing has shifted slightly later than earlier projections, with storm development favored during the late evening and overnight hours.
The primary hazards include wind gusts up to 60 mph, hail up to 1 inch in diameter and locally heavy rain that could create ponding on roads and reduced visibility. Confidence is moderate to high (40% to 70%) that thunderstorms will develop, while the probability of storms reaching severe limits remains relatively low at 5% to 15%.
Cities including Green Bay, Appleton, Oshkosh and Manitowoc could see thunderstorms, though the strongest activity is expected farther north. Travelers on Highways 29, 41 and other regional routes should be prepared for rapidly changing weather conditions late this evening.
Residents are encouraged to secure loose outdoor items, have multiple ways to receive weather warnings and move indoors immediately if thunderstorms approach. The National Weather Service will continue monitoring storm development, and additional watches or warnings may be issued if conditions become more favorable for severe weather overnight.
