Day 5: Looking back, looking ahead

PECOS, Texas -- Although we did manage to find a small thunderstorm with a little lightning and rain over extreme southwest Texas, Thursday was mainly just a relaxing drive through the semi-arid terrain of west Texas.

We are down this far south because the jet stream pattern is pushing south of Canada to such an extent that it is driving most of the moisture and warmth out of the United States. The extreme southern rim of Texas and eastern New Mexico looks like the only real shot at thunderstorms the next few days, as some warmth and moisture may linger, and a few disturbances along with the terrain may aid in allowing some convection to occur. The chances of severe weather are slim, but never zero when there are thunderstorms.

Down time between storm chases can be beneficial, helping us get some rest and take care of tasks like washing clothes and buying food. We also use the time to look back and look ahead.

We've taken a look at some of the many photos and video segments from our first two chases. A photo by Trevor Owen (click here for bigger version of image) taken out the back window as we drove away from a close intercept of Wednesday's storm north of Big Spring, Texas, may reveal either an extremely low rotating wall cloud or, quite possibly, a tornado. Many other pieces of evidence point to a possible tornado: A rear-flank downdraft wrapping around the circulation (creating our dust storm) and a radar indication of tight rotation, called a tornadic vortex signature or TVS, are a couple of those. This storm would go on to go through many cycles of new wall clouds and eventually tornadoes forming, as a healthy supercell often does. We were there for at least the first two.

Looking ahead ... we'll be looking for any sign of a pattern change that could yield more widespread storminess next week. Several forecast models are beginning to show just that, but the various models have been in poor agreement. We'll just have to wait and see where we end up going next week, but for now, perhaps we should just enjoy some good Tex-Mex food and see if we can coax out a picturesque storm over the desert.
