Wednesday will be partly to mostly cloudy and hazy. Smoke from the wildfires that are burning in the Pacific Northwest and Canada will continue to filter over the upper Midwest. The Air Quality Alert that was issued on Tuesday was allowed to expire at midnight. The cold front that passed through on Tuesday will bring in a brief cool down and drier air. Temperatures will top out in the upper 70s to near 80 degrees Wednesday afternoon. The average high for today is 82 degrees. With dew point temperatures only near 60 degrees, it is not going to feel as humid or as uncomfortable outside. Today’s rain chances are pretty much as low as they go without officially being zero. A stray shower or storm can’t be ruled across our western counties near the Mississippi River.
