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, November 30 - Sunday, December 6, 2015
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 mostly in the Good range this Monday morning across Wisconsin. Moderate values are being measured in Brown County. Concentrations are expected to remain unchanged for remainder of Monday.
An area of low pressure will move into northern Wisconsin on Tuesday. Colder air will move across the state as winds become more westerly. The slow-moving low pressure system will still be over the region on Wednesday. Air quality will remain in the Good range.
Quiet weather and Good air quality is expected Thursday through the upcoming weekend as a high pressure system moves across the Ohio River valley.
