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.
Thursday, October 20 - Sunday, October 23, 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)
Good and Moderate levels.
PM2.5 air quality is in the Good range in Wisconsin this Thursday. High pressure is building back into the region behind a cold front that passed through last night. Conditions will remain windy and cool through tomorrow, and Good air quality will persist. The weekend will feature more sunshine, warmer temperatures and calmer winds. Air quality will be a mix of Good and Moderate. A weak surface Low pressure system will pass across Wisconsin Sunday into Monday, bringing northerly winds and returning us to Good air quality for the start of the work week.
Extended outlook: High pressure will dominate Wisconsin weather for the early part of next week. Air quality will be Good with the possibility for some Moderate values increasing as the week goes on.
