The highest AQ index in Minnesota (as of 14:00 CDT) is currently the Rochester Area area. Particle Pollution (PM2.5) is measuring at 54 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Particle Pollution (PM2.5) will be in the Minnesota Arrowhead area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
A cold front will continue sinking southward through southern MN on Wednesday. The air north of the front is fairly clean. Clouds and scattered showers/thunder will limit ozone formation. Air quality in most of the state will be Green (Good). Some smoke from a wildfire in Ontario may bring Yellow air quality to northern Lake and Cook counties. The weather for Thursday and Friday will be mostly sunny with temperatures close to normal. Other than some light smoke north of Duluth, air quality should remain Green in most of the state on Thursday. On Friday ozone may reach Yellow (Moderate) in the Twin Cities Metro.
