Octane indicates decent upper level divergence aloft in thunderstorm located east of Ft. Stockton 2240Z (1740 CDT). This prompted me to analyze the storm further with base radar data overlaid with ProbSvr v3.

Octane located in the upper left indicates strengthening values in the storm near Ft. Stockton. 

Further investigation analyzing base radar data with ProbSvr indicates the storm is still sub-severe.
