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, February 23 - Sunday, March 1, 2015
Note: Ozone forecasts will resume in late April, when the 2015 ozone season begins.
Particle pollution (PM2.5)
Mostly Good air quality this week.
PM2.5 air quality is in the Good range this Monday morning across Wisconsin. A northwest flow in the upper atmosphere will keep cold air over the Midwest for most of the upcoming week.
Brisk southwest winds will develop today and bring some moderation in temperatures into Tuesday. A cold front passing through the state later Tuesday will usher in the next surge of arctic air. This cold air will remain over the Midwest through the end of the week. Air quality should remain in the Good range for the work week.
Winds will turn southerly and push warmer air and more moisture toward the region next weekend. Conditions will become more favorable for Moderate levels of PM2.5.
