To set this up...

1) We live in a valley, so from the house only see a bit of sky.

2) We live in Fannin County, GA - "Gateway to the Mountains"

In any case, walking the dogs up out of the valley today I looked south towards our house and saw this:

I wish I had a time lapse. It was weird in that the wind was blowing pretty strong from the west, right to left, and the whole body of the cloud seemed to be moving that way. But over a period of about 15-20 minutes, in spite of the apparent motion, it remained stationary. Hence I think it was probably a standing lenticular formation caused by the rising terrain.

5,000' winds (elevation about 2,000')

Hard to see, but there were little "wavelets" forming on the upper edge:

Which, over time morphed into this:

Note that though a lot of time had passed, and the structure of the clouds had morphed quite a bit, the overall position was still about the same, looking at the tree at the bottom - in spite of the strong westerly winds. I don't know what the orb at the bottom is - probably a reflection.

Clouds like that usually portend turbulence, and sure enough:

A couple of hours later the whole thing has just spread out to pretty much cover the sky.

Anyway, I thought it was cool and it passes for excitement 'round these here parts!

There were some Lenticulars last night / early morning. Wasn't that bad though. Had some areas of 37 kt winds at 5,500 from the NW but smooth. Had some light turbulence below 3,500. We'll see how it goes tonight.
 
Cool pics, I enjoy looking at interesting clouds. Was pondering moisture and winds as I looked at some clouds yesterday afternoon. Had a bit of a washboard effect to them.
 
dang i wish i woulda been in a glider up there. nice looking lenticulars!
 
Yep, saw 'em, too. Back side of that cold front that blew through yesterday. You have some ugly wx heading your way tomorrow night. We may get some ice here in Atlanta.
 
When there is enough of a wave to disrupt the surface at the Owens dry lake bed much of the dynamics below the lenticular become visible due to the alkali dust.

Light sport flying in this valley can be unpleasant.

Good lord. That looks like a nuclear bomb!
