The following images were captured from a quickly exploding "tail-end Charlie" Supercell apart of an equally initiated multi-celled complex which developed northeast of Midland around 2300 Z on April 23, 2007. Synoptically, the Permian Basin was a very favorable region for Supercell initiation due to 1), abundant low level moisture via a strong LLJ and 2), good upper air dynamics inclusive of cold air aloft and vorticity via an Upper Level Low ejecting shortwaves . These attributes provided high CAPE values and adequate directional and speed shear, however a very strong CINH was prohibiting convection". Once forcing overcame the "Cap", locally, strong initiation rapidly ensued. The fist image, above, was taken east of Stanton in Martin County from beneath Rain Free Base looking further northeast at FFD (southeastern facing shelf cloud) and main Rain/Hail core in left center foreground.
The next image, above, shows the incising RFD near Stanton as viewed overhead. Continuing to drive east along Interstate 20 the next image shows the RFD to the left of a developing lowering of
the Updraft Intake Region near Big Spring Texas. The next image is taken just north of the townsite of Coahoma, Tx from beneath the Rain Free Base and Updraft Intake Center looking back to the southwest at the Rear Flanking Line.
Driving
north on SH 820 from Coahoma, a postion was established to view the Mesocyclone from the southwest side or from the RFD perspective whereby the following below image was captured showing aforementioned cutting into the Rain Free Base region.
