Current air quality outlook

Department meteorologists use monitoring data and weather forecast models to predict Wisconsin's future air quality using the Air Quality Index (AQI) [exit DNR]. If warranted, an Air Quality Notice is issued. Below is the latest air quality forecast for Wisconsin.

Monday, August 10 - Friday, August 14, 2020

Ozone

Good to Low-Moderate levels.

Particle pollution (PM2.5)

Good levels.

Weather outlook

Monday - A slow moving cold front will bring multiple chances for scattered, potentially strong, storms across the state today, while conditions remain muggy ahead of the front. Good AQI is forecast, especially after the passage of the front, while some areas in the southeast and along the lakeshore could see concentrations build towards Moderate AQI ahead of it.

Tuesday - High pressure behind the front will lead to much more pleasant and seasonable conditions for Tuesday. Dry, mostly clear skies and Good AQI are forecast.

Wednesday - High pressure looks to be more dominant east of the state, allowing for ESE winds to develop. Temperatures will be a bit warmer and a majority of the moisture looks to remain to our south and west. Good AQI is anticipated for most, with some areas inland creeping towards Low-Moderate AQI.

Extended outlook

A fair amount of uncertainty remains regarding the back end of the week, especially with regards to the moisture to our west and whether or not it makes it far enough east with enough energy to support rain and storm development. Regardless, flow patterns over the lake look to be favorable out of the ENE, which typically provides Good AQI to lakeshore areas. Further inland, where a southerly component to the flow is more likely, Low-Moderate AQI remains possible.
