Minnesota has air quality concerns for the weekend. An Air Quality Alert has been issued for fine particulate matter across all of the state through midday Sunday. The Minnesota Pollution Control Agency issued this alert due to smoke from wildfires in western Canada continuing to impact the state's air quality. The Air Quality Indices (AQIs) will range from 101 to 150, which is a range where the air quality is unhealthy for sensitive groups of people - people with lung or heart disease, older adults and children that are at greater risk from the presence of particles in the air. These groups should limit their prolonged exertion, especially if outdoors or near a source of pollution. Source: AirNow.Gov The forecast late Saturday into Sunday does call for improving air quality as wind speeds up and turns southwesterly, helping to clear the smoke out of the region.
