A strong upper-level storm system moving out of New Mexico generated a thin line of thunderstorms that raced across West Texas during the afternoon and evening hours of December 14th, 2012. Severe wind gusts, small hail, blowing dust and even a few tornadoes were reported from the TX South Plains north into the TX Panhandle during the late afternoon.
