For what its worth, fords spec for temp drop is 40 degrees. So at 102, it should be blowing a maximum of 62, however that is with max AC on. Fresh air will skew the numbers, as you are not cooling colder air. The max AC as said turns recirc on, in doing that it will be cooling cabin air only, which as you drive should be dropping in temp, where with the fresh air on, the longer you drive, it may get hotter.
