Hot temperatures, a dryline, and a weak upper level disturbance were sufficient to initiate a broken line of thunderstorms across the western South Plains on the afternoon of the 17th. The storms accelerated eastward producing brief heavy rain and strong to severe wind gusts as they moved across the Caprock through the late afternoon and evening. The most significant storm affected the southern portion of the town of Brownfield (Terry County). Reported damage was significant enough to warrant an NWS storm survey the next day. This storm survey revealed a wet microburst with estimated winds of 100 to 105 mph affecting Brownfield. Numerous power poles and mobile homes were damaged, and one mobile home was destroyed. Two center pivots were also destroyed and numerous car windows were broken at the Rudd Correctional Facility.
