Weather at Airventure

[PaulDow]

Being that the convention is held on planet earth, there’s no telling what the weather will be.

But it was during the July heat wave of 1995 that the highest dew point of all was measured in the Upper Midwest: 90° at Appleton, Wisconsin at 5 p.m. on July 13th of that summer. The air temperature stood at 101° in Appleton at that time leading to a heat index reading of 148°, perhaps the highest such reading ever measured in the United States.

I don’t think there’s any way to prepare for that.
