*Another cold shot on the horizon!
It’s a ways out, but the long range computer models are in good agreement (so far) in showing another lobe of unseasonably chilly air oozing south out of Central Canada and into Minnesota during the middle of next week. The map below represents the temperature forecast at 850mb valid for next Wednesday PM. Widespread +4 to +6C H85 temps over the Upper Midwest, quite chilly for early August. (Source, 18z GFS model)
