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.

Anyway, any one here think it is really the case that the planes are
causing the temperature to be lower on the approach end of the runway? I
guess if he monitored the ATIS frequency to find out which runway was
active when he drives by every day, he would have a better idea.


Which airport in OKC???
