...UPDATED AIR QUALITY ADVISORY REMAINS IN EFFECT UNTIL 11 PM CDT
FRIDAY...

The Wisconsin Department of Natural Resources has updated the Air 
Quality Advisory for PM2.5 which will now remain in effect until 
11:00 PM CDT tonight.

Canadian wildfire smoke has remained evident across Wisconsin 
Thursday night through Friday morning. However, surface 
concentrations continue to be lower than initially anticipated. 
Southerly winds will increase in magnitude tonight into tomorrow, 
preventing additional transport of smoke into Wisconsin from the 
north. Concerns for smoke-enhanced ozone have also decreased with 
the lower levels of observed smoke. The advisory will be cancelled 
at 11 PM CDT tonight. People with heart or lung disease, older 
adults, and children should still reduce prolonged or heavy exertion 
if possible.
