Forecast Discussion: Independence Day, smoke originating from fires in Canada has been transported into the Twin Cities area, leading to elevated particle levels. Furthermore, fireworks displays will increase particle concentrations locally. In addition, mostly sunny skies and temperatures in the 80s will enhance ozone formation. Therefore, despite light to moderate south-southwesterly winds dispersing some pollutants, AQI levels will be Moderate. Tomorrow, moderate south-southwesterly winds ahead of an approaching frontal boundary will bring additional pollutants into Minneapolis-St. Paul. Furthermore, mostly sunny skies and warm temperatures will continue to support ozone formation, keeping AQI levels Moderate. Monday and Tuesday, as the weak front moves through eastern Minnesota and departs to the east, winds will shift to northwesterly in the Twin Cities, effectively dispersing pollutants and leading to Good AQI levels on both days. Wednesday and Thursday, a surface low-pressure system developing over the central Plains will cause winds to shift to southerly in Minneapolis-St. Paul, transporting regional pollutants into the area. Furthermore, partly to mostly sunny skies and warm temperatures will increase ozone formation. As a result, AQI levels will be Moderate on both days.
