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 1 - Sunday, February 7, 2016
Note: Ozone forecasts will resume in late April, when the 2016 ozone season begins.
Particle pollution (PM2.5)
Good and Moderate air quality this week.
Particle pollution (PM2.5) air quality is a mix of Good and Moderate levels this Monday morning across Wisconsin. The Moderate levels were found across the southern part of the state. Winds will stay light and the PM2.5 levels should remain a mix of Good and Moderate.
As a storm system tracks towards the Midwest on Tuesday the winds will swing to an easterly direction and increase in speed. This should help keep PM2.5 levels in the Good range.
As the storm system pushes east of Wisconsin on Wednesday colder will flow into the region on northwest winds. Good air quality should prevail into Friday. Warmer air pushing back into Wisconsin may lead to some Moderate values on the weekend.
