Texas Climate Report: July 2003

The month of July was quite interesting in Texas. There was a mix of weather across the state from Hurricane Claudette, to drought in the Trans Pecos region. For the most part the majority of the state experienced a summer time pattern of hot temperatures, and below normal precipitation. Ten first-order Texas stations received below normal precipitation, which was also correlated in some cases to the slightly above normal mean temperatures for the month. The cities of: Corpus Christi, Del Rio, and San Antonio were fortunate to be in the path of the remnants of Hurricane Claudette. San Antonio received 400% of their normal monthly rainfall for the month of July with a total of 8.12 inches.

Severe weather wise the state was quite lucky to report very little damage due to hail, tornadoes, or high wind. On the 1st, 4th, and 7th, tornadoes were reported in Bee, Nueces, and Wharton counties which caused minimal damage to structures in the area. There were also a few high wind and hail reports on the 10th, 11th, 13th, 22nd, and 23rd, which also caused minimal damage. The most significant event of the month was the landfall of Hurricane Claudette on the 15th. As a result of this system, a tornado was reported in Port Lavaca County, causing damage to a few homes. High winds of up to 100 mph from unofficial reports were recorded as well. The month of July came to a close with warm and dry conditions.
