Temperatures in the upper 90s/lower 100s and dewpoints in the mid 70s/around 80 created tremendous instability featuring SBCapes 6000-8000 j/kg, downdraft capes 1500-2000 j/kg and hail capes 1500-2500 j/kg. Also of note: very warm surface-700 mb temperatures and 500 mb temperatures -10 to -12C generates 700-500 mb lapse rates around 9 c/km. Thunderstorms fired along an inland surface trough axis; multicell thunderstorms then generated cold pools which drove severe convection through virtually the entire forecast area.
