Forecast Discussion: Today, moderate south-southeasterly winds will transport regional pollutants into Minneapolis-St. Paul, and a moist air mass will support the production of particles. These conditions, will result in mid-Moderate AQI levels. Tomorrow, a low-pressure system will move across southern Minnesota, enhancing vertical mixing in the atmosphere and producing moderate winds in the Twin Cities. These weather conditions will help to disperse pollutants; however, pollutant carryover from previous days will result in low-Moderate AQI levels. Tuesday and Wednesday, light to moderate northwesterly winds behind the departing low-pressure system will disperse pollutants and transport a cleaner, drier air mass into Minneapolis-St. Paul. Therefore, AQI levels will be Good on both days. Thursday, southwesterly winds will develop ahead of a fast-approaching low-pressure system, bringing some regional pollutants and moisture into eastern Minnesota. However, low pollutant carryover from previous days will keep AQI levels Good. Friday, the low-pressure system will rapidly move through Minnesota and depart to the east, enhancing mixing in the lower levels of the atmosphere and shifting winds to northwesterly. These weather conditions will effectively disperse pollutants, yielding Good AQI levels.
