Convective initiation began in late afternoon-early evening in the southeastern Permian Basin along and south of a weak surface cold front in moist lower levels and moderately unstable air aloft (MUCape values near 2000 J/kg), due to Upper Level amplified troughing to the north which when coupled with surface heating had eroded convective inhibition. All following images were taken from Midland looking southeast at developing storms, approximately 5o miles distant, in Reagan and Irion counties with a 70-300mm lens. The first image is zoomed at developing convective growth in Reagan county at approximately 0130Z. This cell became severe warned by NWS/MAF shortly afterward. Two additional images after warning occurred, noting crispness of intensification, (1) and overshooting top above vertical scalloped striations atop initial anvil spreading, (2).
