The highest AQ index in Minnesota (as of 12:00 CST) is currently the Southern Twin Cities Metro area. Particle Pollution (PM2.5) is measuring at 82 (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 Northern Twin Cities Metro 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 wintertime weather pattern favorable for the formation of fine particle pollution is ongoing as of this Monday afternoon, and should remain through the next several days. Broadly speaking, this pattern involves stagnant air from light winds and a temperature inversion across the region, coupled with mild temperatures across widespread snowpack resulting in increased humidity. Therefore, despite the potential for light rain and freezing rain across portions of central and southern Minnesota this evening into Tuesday, the Yellow (moderate) AQI category is most likely for most of Minnesota through Tuesday. Increased wind and/or temperatures may reduce air pollution levels into the Green (good) AQI category for much of the state from Wednesday into Thursday - the Twin Cities has the best chance for lingering Yellow AQI. Eventually, a larger storm system is expected to bring breezy winds and cooler, much cleaner air across the entire state by the weekend.
