An active round of severe weather affected the Permian Basin during the evening of the 5th and the early morning hours of the 6th. An upper level disturbance interacted with a cold front to ignite thunderstorms that resulted in all modes of severe weather. Storms initially formed across the northwest parts of the Basin, with one of the first storms to show supercellular characteristics resulting in damaging hail between Kermit and Notrees. A supercell storm also developed in western Martin County, and propagated south into Midland County. This storm resulted in large hail and severe winds in Midland. Meanwhile, a large cluster of severe storms moved east across Ector County. These storm systems merged over eastern Ector and western Midland Counties, evolving into a large high precipitation supercell. Strong rear flank downdraft winds raked the city of Odessa on the storm's southern flank. Radar detected a strong low level circulation just west of the Midland International Airport, but storm spotters and post-event surveys found no evidence of a tornado. As the storm propagated southeast, damaging rear flank downdraft winds destroyed a carport along Farm to Market Road 1788 in western Midland County.In addition, a broken line of strong to severe thunderstorms developed within proximity to the frontal boundary over the northeast Permian Basin. Area warning radars detected a well-defined coma-head type circulation on the northeast part of the line. This circulation strengthened as it moved southeast into northern Mitchell County. Several rural residents observed a tornado southeast of Loraine.
