On the first supercell of the day that I intercepted, a broad, scuddy, poorly defined wall cloud narrowed and tightened up noticeably just a mile or two to my west, about the time a radar-based tornado warning was issued. It assumed a tilted, somewhat conical shape with peak low-level rotation strength right at this time, and I was watching the ground beneath closely for evidence of debris that never appeared, ready to report tornadogenesis if necessary. Quite often (most often), when I’m in optimal yet safe position for viewing, and contrast is best (on what was an otherwise hazy day), the concentrated cloud-base rotation area fall apart. [For a highly uncommon exception somewhat resembling this, look here.] This fell apart, but not before tantalizing teasing. The storm would move northeast into a road hole, get warned another time or two, produce no tornadoes, and merge into a mess of convection before another supercell fired west of Brownwood, off the edge of the combined outflow.
