Green Bay, Wisconsin, is set for a mix of patchy smoke, rising temperatures, and a shift to thunderstorms by midweek. Starting Sunday, July 13, the weather will be influenced by wildfire smoke drifting from Canada, leading to hazy skies and air quality concerns.
The National Weather Service and Wisconsin DNR have issued an Air Quality Advisory for several counties due to elevated levels of fine particulate matter (PM2.5) in the air.
Health Risks and Air Quality Advisory
Residents in Green Bay and nearby counties such as Brown, Door, Outagamie, and Winnebago should be aware that the wildfire smoke could cause health problems, especially for sensitive groups like children, the elderly, and people with respiratory conditions.
The advisory will remain in effect until noon on Monday, with PM2.5 levels expected to stay elevated. The smoke will also reduce visibility, making outdoor activities less ideal for some. It’s recommended that people limit strenuous outdoor activities during these conditions and keep medications nearby if needed.
Warm and Dry, Then Thunderstorms Loom
Sunday’s weather will remain dry, with hazy skies and temperatures reaching a high of 84°F. Winds will be light, but the lingering smoke will continue to affect the air quality.
By Monday, Green Bay will experience the hottest day of the week, with highs reaching 87°F under sunny skies. However, a slight chance of thunderstorms will develop late in the day.
The weather pattern will shift on Tuesday, with a 30% chance of afternoon storms, particularly across central and eastern Wisconsin, including the I-41 and I-43 corridors. Storm chances will increase further on Wednesday, with higher odds of showers and storms, along with possible gusty winds.
5-Day Outlook for Green Bay (July 13–17)
Sunday (July 13): Patchy smoke, mostly sunny, high 84°F.
Monday: Sunny and hot, slight storm chance late, high 87°F.
Tuesday: 30% chance of afternoon storms, high 86°F.
Wednesday: 50% chance of showers/storms, partly sunny, high 77°F.
Thursday: Mostly sunny, breezy and cooler, high 73°F.
While the air quality should improve by late Monday, storm chances will increase Tuesday through Wednesday, bringing potential for showers and thunderstorms. Residents are advised to monitor local weather alerts for updates, especially if the smoke lingers or if the storm risks escalate.
Stay Safe and Weather Aware
As the weather continues to shift, it’s important to stay informed about air quality and storm conditions. People in sensitive groups should limit outdoor activities during periods of poor air quality. Keep an eye on the weather, especially if you have travel plans or outdoor activities lined up.
