June 21 was a good set up for late June in the Texas Panhandle. Strong deep layer shear, a sharp dryline and high CAPE would provide a set up for supercells. Mid afternoon an LP supercell developed north of Amarillo and stayed on the triple point for a couple hours. Eventually the storm moved south along the dryline and became an incredible hail producer. It produced hail to cantaloupe size in Amarillo that caused $100m damage. This storm also produced several weak tornadoes.
