Forecast Discussion: Today, a low-pressure system will move through northern Minnesota, increasing atmospheric mixing and producing moderate west-northwesterly winds. These weather conditions will help to disperse pollutants in the Twin Cities, resulting in Good AQI levels. Tomorrow, winds will diminish and gradually shift to southerly as surface high pressure moves across eastern Minnesota. These winds will limit pollutant dispersion in Minneapolis-St. Paul, leading to low-Moderate AQI levels. Wednesday, a surface low-pressure system approaching southern Minnesota from the west will generate moderate southerly winds that will transport additional pollutants and moisture into the Twin Cities, supporting particle production. As a result, AQI levels will remain Moderate. Thursday, moderate to strong northwesterly winds behind the departing low-pressure system will effectively disperse pollutants and bring clean, dry air into eastern Minnesota. These conditions will lower AQI levels to Good. Friday, surface high pressure building over eastern Minnesota will cause winds to diminish, inhibiting pollutant dispersion in Minneapolis-St. Paul. Therefore, AQI levels will be low-Moderate. Saturday, a low-pressure system rapidly moving into southern Minnesota will enhance atmospheric mixing and generate moderate north-northwesterly winds in the Twin Cities, effectively dispersing pollutants and yielding Good AQI levels.
