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 for Wisconsin, which will be updated as needed.
Monday, November 28 - Friday, December 2, 2016
Note: Ozone monitoring season ended on October 15, 2016. Ozone forecasts will resume in late April, when the 2017 ozone season begins.
Particle pollution (PM2.5)
PM2.5 air quality is in the Good and Moderate range throughout Wisconsin this Monday morning. Air quality will improve as winds increase ahead of a low pressure center currently situated near the border of Minnesota and the Dakotas. The approach of the low and associated cold front will bring rain showers today into tomorrow, and air quality will return to the Good range. Wisconsin will experience a dry period tomorrow into Wednesday as the Low passes overhead, followed by possible snow showers Thursday as the Low tracks northeast over the Great Lakes. Air quality will remain Good through Friday.
The surface analysis for Wednesday is shown below
Air quality will remain Good through the weekend as the weather pattern across the Midwest becomes more zonal and High pressure builds back into the region.
