 Brief Description: Tornado touched down on west Airport Drive near Industrial in Sugar Land. 60 injuries with 7 people sent to hospital for further treatment. Damage to several office building roofs in Industrial Park. Additional damage to a Daycare facility at West Airport Drive and Dairy Ashford Road. Roof damage to several residential homes in the Meadows subdivision. Reports of several cars overturned or blown off of road along Airport Drive. A total of 24 tornadoes touched down during this 15 hour period of severe weather in southeastern Texas on November 17, 2003. In addition to these tornadoes, a major flood developed over Harris and surrounding counties during the middle of this tornadic outbreak. Over 300 homes, along with hundreds of vehicles, were flooded. These tornadic storms developed over parts of Wharton and Matagorda counties shortly after sunrise with the first confirmed tornado occurring just east of El Campo around 9:00 am. Strong 500mb upper level troughing over the western U.S. moved from west to east across the Southern Plains. The polar jet stream associated with this 500 millibar trough surged into west Texas and then curved sharply northeastward into the Central Plains. The sub-tropical jet stream was oriented west to east across deep southern Texas. This jet stream pattern was the impetus to strong lower level convergence due to the enhanced upper level divergence. Low level moisture had substantially increased and was about 200 percent of normal by 6 AM. Vertical wind profiles also showed a great deal of low level wind shear with the greatest shear occurring in the lowest 2000 feet. In addition, these veering wind speeds rapidly increased with height. A focus for the thunderstorm development was provided by a weak low level boundary which was aligned southwest to northeast, or generally along the U.S. Highway 59 corridor. This feature was nearly-stationary and thunderstorms repeatedly developed and moved along this boundary. The axis of heaviest rain was coincident with this boundary.

 Brief Description: Tornado began on west shore of Lake Houston, crossed the lake then crossed the east shore in Indian Shores Estates. The air survey located minor damage and trees down on the west shore of the lake. Eye witnesses observed the tornado over the lake and WSR-88D reflectivity/ velocity data indicated a strong low-level mesocyclone near the west shore of the lake just prior to the first tornado reports. The tornado moved across the east shore of the lake and into Indian Shores Estates around 1710 CST and produced a damage path 300 to 400-yards wide and approximately 2.5 miles in length that ended about 1.5 miles east of the intersection of FM 2100 and Heathergate. One woman was killed in a mobile home, and 20 received injuries in the area.

 Brief Description: This tornado was probably the most significant in strength and length that occurred this day. Several homes and mobile homes received major damage. There was one injury when a young boy was in a mobile home when the tornado picked it up and wrapped it around a tree. Damage to trees was extensive with many trees being snapped off above the ground. This storm was surveyed from the air and had continuous tree damage from Midway to Shepherd in San Jacinto County.
