My dad drives along the south side of OKC to work every day and his OAT in
his car always goes a few degrees colder around the where the extended
centerline for the runways would intersect the road. Then it goes right
back up after he is through that area. He thinks this is because the
airplanes are descending from very cold air and bringing down some of it
with them. He has noted that this isn't always the case but it often is.
You would think most of the traffic would be landing from the north since
our winds are mostly from the south, but it seems like I see a lot of
traffic coming in from the south, maybe because it is easier for the
traffic from DFW to just come strait in.


If I were to guess (and it's just a guess) I would suspect that the long
open space along the runway allows the wind to blow a little faster (less
drag from buildings and stuff) and pulls down a little more cool air from
higher altitudes.
