Wow! That was quick, Clark. Thanks for the explantion. I saw the weaker impluce behind it and it just made me question it more. I tried to read up on gravity waves but I think they're way over my head for my understanding of meteorology. I guess it's best just to know they distrupt the flow in the atmosphere and not try to go too much deeper.

So to sum it up you believe this is some kind of gravity wave which is causing a slight change in the moisture/IR temp(you can just make it out on IR, too. Prob be very interesting if it was still daytime), but it's not really causing much change in weather?

Yep, pretty much. It may last for some time through the night, but is more of just an interesting phenomenon. -Clark
