On the afternoon of the 13th, a dryline moved east to the Interstate-27 corridor. By the early evening, thunderstorms continually redeveloped around Hall and Motley Counties. These storms were able to take advantage of a very unstable atmosphere and produce hail up to two inches in diameter. Several rounds of thunderstorms affected Hall and Childress Counties, particularly around the Estelline (Hall County) area. Large hail and severe winds resulted in numerous reports of damage in Estelline with one of the storms. A Texas Tech University West Texas mesonet site near Estelline, which was completed only three days prior, was damaged due to large hail. The repeated rounds of thunderstorms also resulted in flash flooding along Farm to Market Road 658 south of US Highway 287 in Hall County.
