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 20 - Sunday, October 26, 2014
Note: Ozone forecasts will resume in late April, when the 2015 ozone season begins.
Particle pollution (PM2.5)
Good air quality this week.
PM2.5 air quality is in the Good range this Monday morning across Wisconsin. A cold front will pass through southern Wisconsin early today. Clouds will increase later this morning and linger through the evening. High pressure behind the front will bring quiet weather and cool temperatures to the region through Wednesday. Another trough of low pressure will bring a chance for rain showers on Thursday. Quiet weather and mild temperatures are likely next weekend. Air quality should remain in the Good range through the week. With warmer temps and light southerly winds possible next weekend there is some possibility the PM2.5 levels may reach the Moderate range at a random site.
