Additional Details: 
Canadian wildfire smoke will impact Wisconsin's surface air 
quality over the coming days, causing the PM2.5 Air Quality Index 
(AQI) to range from the Unhealthy for Sensitive Groups (USG; 
Orange) category to the Unhealthy (Red) category. It will be 
possible for NowCast AQI values to reach the Very Unhealthy 
(Purple) category. 
 
Smoke impacts are already being observed in northern Wisconsin on 
Tuesday morning, and the smoke is expected to slowly travel south 
through northern Wisconsin Tuesday. Overnight Tuesday into 
Wednesday morning, the smoke will continue south, impacting most 
of the state by noon Wednesday. The smoke is then expected to 
linger over the state from noon Wednesday until noon Thursday. We 
may see brief improvements in air quality on Thursday before 
smoke moves back into northern areas on Friday. Stay tuned to the 
air quality forecast as conditions can change quickly during 
wildfire smoke events.
