A strong upper level storm system moved across the Southern Plains on the 20th. This system produced high winds and blowing dust over much of West Texas. The highest winds were observed across the extreme southern Texas panhandle into the northern South Plains. Wind speeds increased late in the morning and quickly subsided late in the afternoon as the storm system moved east of the region. Several accidents were reported due to the high winds. A tractor trailer was blown over on Interstate 27 in Lubbock County just north of Lubbock Preston Smith International Airport. The driver was taken to the hospital with non-life threatening injuries. An additional tractor trailer blew off the road in Hockley County on Farm to Market road 2130.
Near zero visibilities due to blowing dust caused an 11 vehicle accident in Hall County, three miles north of Estelline on US Highway 287. Two vans, four passenger vehicles and five tractor trailers were involved in this wreck with four injuries reported.
