We’ve had a lack of severe weather this season. While we saw some weather Saturday and may again late Wednesday, overall severe weather warnings are at their lowest for this point in the season since 1995.

Air quality will remain an issue as smoke lingers in eastern and southern Minnesota. An air quality alert continues essentially through midnight Wednesday (the graphic is confusing about the time).

The smoke is circulating back in from the south after moving away from portions of Minnesota late Tuesday. The reason is that an area of high pressure with clockwise circulating air continues to move east.

This initially pulled in the smoke from the northeast then pushed it away to the southwest and now is bringing it back from the south. The worst air is over southern Wisconsin and Illinois.
