What does the chain of orange circles represent? (OK panhandle, south across west TX to Mexican border)

that is the Marfa Dry Line, boundary between the cold air mass from canaday and the gulf moisture. watch for all the fun weather, and good soaring, along there.

aka Dew Point Front
Yes one of the local wx phenoms I had never experienced til moving here, it is just like a warm or cold front in that it is a boundary between two different air masses; but instead of a division based upon temperature, it is based upon moisture. Typically the eastern side is Gulf moisture and the western side is dry desert air. It drifts back and forth but mostly we find it appearing in NM and sweepting eastward during the daytime, blowing the moisture and clouds out of here.
You can see it on current weather charts by significant changes in the DPs, ie a >10degree change along a distinct boundary.
Occasionally it is associated with nasty weather such as huge walls of dust, or lines of thunderstorms.
I have flown through various milder states of dry lines and it is always a rough ride, just like a cold front.

Definately a dry line. They were talking about this morining on the local weather. Possibility of circulating T-storms due to jet stream overhead, moist southerly surface winds and that dry line moving east. Not a good afternoon to be in NW Oklahoma and TX panhandle.
 
Thanks guys, glad to be here. A little history I guess is in order to introduce myself. Started flying when I was 17. Got real close to having all of the requirements met for my ticket. My instructor ended up moving off, I ended up graduating high school, getting married and having kids. I put a few more hours in after my first son was born, but just couldn't get all the needs met if you know what I mean. The ticket was definately on the back burner. Now my oldest son is off to Oklahoma State, my youngest is in high school, my business is doing well, so I am back in the cockpit. Have already logged about 6 hours in just a couple of weeks. My skills are still there, a little rusty, but still there. I even made a pretty good crosswind landing the other day. Hopefully my solo will come back pretty quick. I can't believe how good it feels to be back in the cockpit and having the wheel and throttle back in my hands. The hunt for the ticket is not on the back burner any longer, I hope to have it by years end. I'm glad I found this forum. Seems to be alot of good reading here. Glad to be a part.

yep, those drylines can be pretty nasty. Used to fly from ATL-SAT (san antonio) a lot, and the dryline was very distinct. Lots of CU's, TCU's, and haze along the gulf states, then all of a sudden very clear and dry skies on the other side of the line. They tend to produce pretty decent storms too, as stated above.

Seems like they always formed around the panhandle, and never moved much further east than Dallas.
 
Yep, you know the ones. After the cold (cool) front moves on through, that dry line diminishes and conditions improve dramatically.
