Current air quality outlook
Department meteorologists use monitoring data along with weather predictions to determine when and where an air quality notice is needed. The meteorologists submit daily air quality forecasts for eight Wisconsin cities to EPA's AirNow website. Below is the current air quality forecast, which will be updated as needed.
Monday, August 18 - Sunday, August 24, 2014
Ozone and particle pollution (PM2.5)
Mostly Good air quality early this week with Moderate possible next weekend.
Ozone and PM2.5 air quality is in the Good range this Monday morning across Wisconsin. Rain showers and storms are possible late this afternoon across southern Wisconsin; this will help keep air quality in the Good range. A low pressure system will move across the state on Tuesday with rain showers gradually ending. Westerly winds behind the departing system will keep air quality in the Good range through Wednesday. A warm front moving towards the region will bring more rain chances Wednesday night into Thursday. The expected cloud cover and rain should maintain the Good air quality for Thursday. The exact position of the frontal boundary will play an important role in determining possible Moderate or higher air quality next weekend. As of now, the forecast calls for Moderate air quality next weekend.
