Green Bay, Wisconsin, is facing a mix of heat, storm chances, and a wet weekend that could affect Fourth of July celebrations and travel plans across central and northeast Wisconsin. Thunderstorms are expected to develop Friday evening, potentially disrupting fireworks displays as families gather outdoors. Travelers from Green Bay to Wausau should prepare for possible delays, especially on Highway 41, as storms and heavy rain move through the region.
Stormy Conditions and Travel Disruptions
According to the National Weather Service in Green Bay, isolated thunderstorms could begin Friday evening, with a more widespread round of storms and heavy rain expected on Saturday afternoon and night. Wind gusts could reach up to 60 mph, and hail near 1 inch is possible, especially along the Highway 41 corridor from Appleton to Marinette. These storms could cause significant disruptions, so travelers should be prepared for slick roads and low visibility.
Heat and Humidity on Friday
Friday’s high temperature will reach 89°F, but the heat index will make it feel more like 96°F due to the high humidity. For those planning outdoor activities like barbecues or parades, it’s important to stay hydrated and avoid prolonged sun exposure, particularly during peak hours. While Thursday will bring calm and sunny weather statewide, Friday’s heat combined with the storm risks could make for an uncomfortable day outdoors.
Looking Ahead: Flash Flooding and Stormy Conditions
Saturday presents a greater risk of severe weather, with a 30% chance of storms starting after 1 p.m. These storms could bring heavy rainfall and the potential for flash flooding in low-lying areas. By Sunday, the chance of storms and showers increases to 50%, and the high will drop to 81°F. Monday will bring a brief break, with mostly sunny skies and a high of 75°F, before storm chances return Tuesday with a high of around 79°F.
