which produced reported damage. The largest and longest duration tornado
developed to the west-southwest of the town of Happy, Texas and had a maximum

as determined by a survey conducted by the NWS Forecast Office in Amarillo,
Texas. Six other tornadoes which have been confirmed across Lubbock's service 
area were all rated either EF-0 or EF-U (unknown).
