I was expecting to see Phoenix high up on the list due to our Monsoon
season (T-stms most every day), but since the season only lasts about
2.5 months, I suppose the rest of the year brings the average down
pretty substantially.

I can personally vouch for Great Falls, MT's high ranking on the
windy city list (next page). GTF is the only place I've ever had to
cancel a flight because it was too windy to untie the plane.
