IMPACTS...Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, may experience health effects. ADDITIONAL DETAILS...This alert is for a combination of smoke and ozone. A band of smoke from wildfires in Quebec is currently moving west across the Great Lakes and Wisconsin. Smoke will cross into eastern Minnesota late Sunday morning. The smoke may make it as far west as Rochester and St Cloud. Air quality should improve across east central and southeastern Minnesota tomorrow morning. Some smoke may linger across southeast Minnesota through Monday. In addition, sunny skies, light winds, and warm temperatures will allow ozone to form from the Twin Cities to St Cloud. PRECAUTIONARY/PREPAREDNESS ACTIONS... Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, should limit prolonged or heavy exertion. Reduce or eliminate activities that contribute to air pollution, such as outdoor burning, and use of residential wood burning devices. Reduce vehicle trips and vehicle idling as much as possible. Keep windows closed overnight to prevent smoke from getting indoors. && For information on current air quality conditions in your area and to sign up for daily air quality forecasts and alert notifications by email, text message, phone, or the EPA AirNow mobile app, visit quality.

Twin Cities metro area highs are projected to be in the lower 80s Tuesday and Wednesday, followed by mid 80s Thursday and Friday.

Rain chances

There were a few scattered showers in far southern Minnesota late Sunday morning, moving southwestward. The heating of the day could lead to an isolated shower or thunderstorm anywhere in Minnesota and western Wisconsin Sunday afternoon and early evening, but most locations won’t see any rain.

One forecast model shows a better chance of scattered showers and thunderstorms in far northern Minnesota Sunday evening.

Minnesota and western Wisconsin will probably see some scattered showers and thunderstorms on Monday. The National Oceanic and Atmospheric Administration’s High-Resolution Rapid Refresh model shows the potential rain pattern from 4 a.m. Monday to 11 p.m. Monday:
