Multiple tornadoes touched down across the Panhandle, mainly areas between Lubbock and Amarillo and points eastward. A large tornado prompted PDS tornado warnings for portions of Randall, Armstrong, and Carson counties.^{[32][33][34][35]} After surveys, it was determined an EF2 tornado moved from southwest of Happy in Swisher County to east of Canyon in Randall County. As the tornado dissipated, a new tornado, rated EF1, formed and moved into Armstrong County, passing over Palo Duro Canyon. A third tornado was spawned just northeast of the second one, also crossing from Randall to Armstrong and lifting near Washburn, just before crossing into Carson County. Another EF2 tornado caused minor damage in Clarendon before strengthening and causing major damage near the Greenbelt Lake Reservoir.^[36] The final tornado of the day was a EF2 tornado that touched down southwest of Ensign and caused minor damage including several sturdy wood electrical poles that were snapped.^[37] Damage totaled $1.285 million.^[38]
