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, March 3 - Sunday, March 9, 2014
Note: The ozone season ended October 15. There will be no ozone forecasts until April 2014.
Particle pollution (PM2.5)
A mix of Good and Moderate air quality this week.
PM2.5 air quality is in the Good range this Monday morning across Wisconsin. Moderate values are likely on Tuesday as the winds become very light. High pressure centered over northern Ontario will build into Wisconsin on Wednesday and Thursday. Generally, Good air quality is expected those days. Later Thursday, winds will swing to a southerly direction as warmer air heads toward the region. Moderate air quality could develop late Thursday into Friday. A passing cold front later Friday should bring northerly winds and Good air quality for Saturday and Sunday.
