Wednesday, July 10th, provided a hot day. Temperatures soared into the upper 90s and lower triple digits, as high as 106 degrees at Post. The extreme heat, coupled with a southwestward moving boundary containing rich moisture in its wake, was enough to generate scattered thunderstorms Wednesday afternoon. Although wind shear was weak under a building upper level ridge, strong instability was sufficient to fuel storms that occasionally flexed to severe levels. | |

The initial thunderstorms developed across the south-central Texas Panhandle and quickly became severe. Additional storms then formed as the activity and associated outflow boundaries moved southwestward. Several other storms became strong to severe as they developed into the southwest Texas Panhandle and northern South Plains. | |

One particularly intense storm formed on intersecting boundaries directly over the Lubbock Airport. Early on in its development two brief landspout-type tornadoes (one can be seen at the top of this page) formed as the rising air stretched out the already rotating air along the boundaries. These landspouts did no known damage. However, the storm went on to produce hail slightly larger than quarters along with a peak measured wind gust of 78 mph at the Lubbock Airport. | |

The severe wind gust did cause damage to a couple of buildings between the Lubbock Airport and the USDA in northern Lubbock County, as seen below. | |

Another severe storm just to the north, across southern Hale County (pictured below), also generated damaging winds. The intense winds from this storm overturned a center pivot and removed the roof of a school house. | |

The individual storms, though briefly quite intense, didn't last very long as their outflows quickly spread out from them. This acted to cut of the storms from the moist/unstable air, but it did also kick up dust and force additional new storm development, allowing the cycle to repeat itself. | |

The activity quickly diminished by early evening, but not before dropping small pockets of moderate to heavy rainfall. The Lubbock Airport officially record 0.51 inches of rain from the severe storm. After a quiet mid-late evening, another round of strong to severe thunderstorms dropped southward out of the eastern Texas Panhandle in the predawn hours of Thursday, July 11th. One storm dropped an even 2 inches of rain in Memphis before diminishing. | |
