Scattered thunderstorms developed ahead of an approaching dry line and cold front ushered into the area by a strong upper level low pressure system moving across the Texas/Oklahoma border. Thunderstorms first developed during the mid-morning hours near Austin and spread eastward into Burleson and Brazos counties by 11 AM. Additional activity later in the day began with a cell forming near Brenham that became severe and prompted several severe thunderstorm and tornado warnings as it moved east across portions of Grimes, Montgomery, and Liberty counties. Additional thunderstorm development to the south of this storm produced numerous reports of hail up to the size of baseballs in Harris County, including reports at both Bush Intercontinental and William P. Hobby airports.  The event ended as the thunderstorms moved out of the Houston/Galveston County Warning Area by 7 PM.
