Green Bay, Wis. — Fireworks celebrations across Wisconsin could fizzle Friday evening as thunderstorms roll in, just as families gather outdoors for the Fourth of July. Heat, storm chances, and a wet weekend are all in play across central and northeast Wisconsin — and travel could be affected from Green Bay to Wausau.
According to the National Weather Service in Green Bay, isolated thunderstorms may spark Friday evening, with a more widespread round of storms and heavy rain likely beginning Saturday afternoon and continuing into Saturday night. Wind gusts up to 60 mph and hail near 1 inch are possible, especially along the Hwy 41 corridor, affecting travelers from Appleton to Marinette.
Heat will also be a factor. Friday’s high of 89°F will feel closer to 96°F due to humidity. Those planning outdoor barbecues or parades should hydrate and avoid prolonged sun exposure during peak hours.
Thursday will be calm and sunny statewide, but Independence Day celebrations could see interruptions in central counties like Waupaca and Brown. Saturday poses a more significant threat, with flash flooding possible in low-lying areas.
Looking ahead, thunderstorm chances continue each day through Tuesday, with cooler, more stable air arriving midweek.
