DVN has 71 in the point for Wed which would tie the all time high for December at MLI. Dewpoints look like they'll be AOA 60 degrees as well, which makes reaching that temp even more impressive.
Wednesday evening is looking pretty wild with whipping south winds possibly up to 50 mph with temps/dews holding in the mid-upper 60s until at least midnight. Out in central/western Iowa the Euro is advertising 60-65 mph gradient winds early to mid evening behind the cold front.
