Northeast Minnesota. * WHEN. From 8 AM CDT Thursday to 6 PM CDT Friday. * IMPACTS. Some members of the general public may experience health effects. Sensitive groups, such as people with lung disease (including asthma), heart disease, and children and older adults, may experience health effects. * ADDITIONAL DETAILS. Heavy smoke from Canadian wildfires across southeast Manitoba will drift southeastward around an area of high pressure into northeastern Minnesota beginning Thursday morning. This smoke may linger near the shores of Lake Superior overnight Thursday into Friday morning. On Friday, a second round of heavy smoke from several large wildfires across Manitoba and Saskatchewan will likely be transported south into Minnesota behind a cold front. This round may impact a larger area of Minnesota, and additional air quality alerts may be needed.
