A tornadic supercell formed northwest of Sundown, Texas during the early evening hours of June 19th, 2013. An unusually moist atmosphere behind a westward moving boundary (from morning convection) generated an isolated supercell south of Morton around 5 pm CDT. This storm would evolve into a tornadic storm as it moved very slowly into western Hockley County. An EF-2 tornado formed around 5:40 pm CDT (350 yards wide with a path of 2.4 miles long)...tornado damaged oil-field buildings and equipment northwest of Sundown. Very heavy rain (and baseball-size hail) was reported in Hockley County due to the very slow movement of the storm. A second supercell formed on the outflow boundary in northeast Gaines County producing very large hail in parts of western Dawson County...between Welch and Lamesa. Additional storms brought hail and torrential rain to Muleshoe/Bailey County areas during the evening.
