Same old story...CAPE and shear should be adequate for supercell
development in western Texas. Initiation should be along either the dryline,
warm front, or local escarpments.
After a 30 minute delay, we departed OKC at 1958 UTC with the NCAR Electra following 30 minutes behind. The FC suggested a reconnoiter leg west of Childress, TX along 34.5N to determine the location of the dryline. The dryline was found at 101.2W on the caprock. One set of stepped traverses was performed at 34.5N. Cu/Sc seemed more appealing to the north, so we adjusted our stepped tranverses northward to 35.0N, coordinating the INIT pattern with the Electra. Five complete stepped traverses were accomplished well documenting the dryline with 2 aircraft, CLASS sounding launches, and probe transects. Although the day was a bust, a good dryline dataset, along with the data from the ETL radiometer, was collected.
An interesting observation....the echoes which developed to our south showed 6 old anvils and 2 towers as we tracked for OKC. The pulsing nature of the multiple towers was clearly evident. We landed at OKC at 0109 UTC, along with the Electra, consuming 5.4 flight hours.
