John,
As a general rule; for every 1000 ft. elevation gain you drop 4°. Manitou Springs is at 6320ft and an average June temp. of about 60° while Pikes Peak is at about 14000ft.
So you can expect to drop roughly 31° by the time you summit to a chilly 30°. Also, don't forget about the afternoon thunderstorms!
Again, thanks so much for the Cobra ride. You never forget the first time you drive one of these things!
Mike.
