Convection began as early as 2030Z in the western sector of the region. The atmosphere was very unstable, comparable to the day before, but effective bulk shear was forecast to be higher later in the afternoon as an Upper Level Closed Low moved east from northwestern Mexico with accompanying height falls and acceleration of the Low Level Jet. Leaving Midland at around 2100Z, a decision was made to target developing convection in Winkler county with movement to the northeast. The first image, above, is from a radar capture while in transit on SH 18 at 2145Z showing warned county, Andrews, of severe storm with hail. The following digital image is taken from SH 181, looking north at warned storm tower, on right, and tailing back-building convection, to left. The next image is a closer view of warned storm in central


A decision was made to turn around and target what appeared to be a developing SuperCell located near the Pecos River near the intersection of Ward, Pecos, and Crane Counties, near the town-site of Grandfalls, Texas, where the author was present the previous day (should have waited). While driving back to the south the author captured the following image of a collapsing updraft, possibly hail dominate, west of Odessa. The subsequent image is of radar capture of this storm tower which had developed on the northwestern side of the complex with the associated embedded developing SuperCell structure. From this radar capture the intensifying reflectivity can be noted at the bottom of image. The cell vectors, pointing northeast as indicators of both direction and speed would veer toward the east shortly after this time of approximately 2220Z as rotation became persistent. The




The last image, below, is a visble satellite capture at 2245Z of the two areas that were "ground"ob-served. The northern complex of muti-celled towers is noted, Andrews, Gaines, and Dawson counties and the southern supercell structure near the Pecos river is also shown.
