If you look at the soundings Bob you would see that yes its cool but the cold air is very shallow. Maybe 500ft deep at the most so the entire updraft is in warm air. I am surprised it didnt mix out better but with all the rain earlier it just reenforced the cold pool. Thats why these storms are going so crazy in 50 degree temps. A tornado is definitely not out of the question if it can break the line.
