Hail in Terrell County, Texas

A large closed upper-low was located over the northern Great Plains with a shortwave trough to the south within the sub-tropical jet stream. These features helped bring rich moisture and instability into the region. Widespread strong to severe thunderstorms developed across much of the region. The Permian Basin and the Stockton Plateau were the two main areas of note. Severe winds, large hail. and a brief tornado was observed in this northern complex. To the south, several long-track, cyclic supercells produced tornadoes and very large hail over rural portions of Pecos and Terrell Counties.
