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 Friday night into Saturday, 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, but conditions will continue to be monitored through the weekend. The current advisory was cancelled at 11 PM CDT Friday. People with heart or lung disease, older adults, and children should still reduce prolonged or heavy exertion if possible.
