A classic, large negatively tilted upper-level trough was progged to move into West Texas by late in the day today.  I wanted to focus on the area just south of the Texas Panhandle where I expected better instability and more discrete, right-moving storms.  My morning target was Plainview, updated to Tulia by early afternoon.  A steady steam of information was delivered to me via cell phone by William Reid to keep me on track.
