Here is a weather model (HRRR model) forecast of near-surface smoke trends through the rest of today into tonight. Overall note is that a cold front moving south through northern Minnesota will result in winds shifting to northwest and then northerly, which will bring the plumes of wildfire smoke into the Arrowhead and eventually down towards the Twin Ports and into northwest Wisconsin towards the very late evening/overnight hours. The smoke is highlighted in brown, with darker shades indicating higher smoke concentrations. US National Weather Service, Duluth, Minnesota
Smoke from the wildfires also is creating dangerous air quality conditions across the region. By Wednesday morning, air quality throughout St. Louis County was expected to reach hazardous or very unhealthy levels.
