Green Bay, Wis. – A hazy sky may be the first sign that conditions are changing again across northeast Wisconsin. Sunshine will mix with increasing wildfire smoke through the day, creating reduced visibility and poorer air quality before a more active weather pattern arrives early next week.
Wildfire smoke is expected to drift back into northeast Wisconsin today, with air quality gradually declining through the afternoon. According to the National Weather Service in Green Bay, higher concentrations of smoke will impact visibility and air quality today, with smoky conditions lingering into Sunday and Monday morning before showers and thunderstorms arrive.
Afternoon temperatures will climb to around 83 degrees under mostly sunny skies. Patchy smoke is expected to become more noticeable later today, especially for sensitive groups, including children, older adults and those with heart or lung conditions. If you spend extended time outdoors, consider limiting strenuous activity and keep windows closed if smoke becomes noticeable.
Travelers along Interstate 41, U.S. Highway 41 and Wisconsin Highway 29 could encounter locally reduced visibility where smoke becomes thicker. Conditions should remain generally dry today, although a slight chance of a thunderstorm cannot be ruled out early. Plan ahead if you’re driving long distances, and allow extra following distance if haze develops.
Sunday remains warm with highs near 83 degrees, but smoky skies continue. By Monday, temperatures rise to around 87 degrees before showers and thunderstorms become likely during the afternoon and evening. The National Weather Service notes there is a Level 2 of 5 severe weather risk on Monday, with stronger storms capable of producing damaging winds.
Tuesday brings a return to sunshine with only a slight chance of an afternoon shower and a cooler high near 81 degrees. The broader 6-to-10-day outlook favors above-normal temperatures across much of the Upper Midwest, suggesting summer warmth will continue beyond next week even as periodic storm systems move through.
