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, October 27 - Sunday, November 2, 2014
Note: Ozone forecasts will resume in late April, when the 2015 ozone season begins.
Particle pollution (PM2.5)
Good air quality this week.
Particle pollution (PM2.5) air quality is in the Good range Monday morning across Wisconsin. A warm front will advance northward into southern Wisconsin today. Temperatures may reach 70 degrees in the south along with somewhat breezy conditions. Cooler air will move in for Tuesday and Wednesday following the passage of a cold front. A surge of even cooler air is likely for Friday and Saturday. Warmer temperatures will return late next weekend. Air quality is expected to remain in the Good range for the week.
