Texas Climate Report: August 2002

August was considerably drier and warmer for most locations around the state compared to July. Almost the entire state reported below normal precipitation except the southeast and the northern Panhandle regions. Galveston and Port Arthur received excessive rain on the 15th, totaling 11.46" and 5.79" respectively. Tropical moisture kept re-developing over the Galveston area, and it continued to move over much of the extreme southeastern counties causing localized flooding. Temperatures were, for the most part, above normal except Austin and College Station, which were slightly below. The western half of the state saw the greatest departures from normal including Midland at 4.4°F above, San Angelo at 3.3°F above, and El Paso at 3.4°F above.

The month started off hot and dry, with some Monsoon moisture entering El Paso, and some scatted sea-breeze shower activity along the coast. El Paso dried out quickly, and the rest of the state continued to stay above normal. A weak front entered the Panhandle region on the 10th giving Amarillo 1.18" of rain. Aside from the soaking rains along the southeast coast, the middle of the month remained hot and dry for the bulk of the state. Some scattered sea-breeze showers popped up during the afternoon, which is typical for this time of year, but all fronts stayed well to the north of the state. A cold front managed to make it through the state during the last week in August. Prior to the frontal passage on the 28th and 29th, several locations reported temperatures well above 100°F including San Angelo and Midland at 106°F, while Dallas reported 98°F and San Antonio reported 97°F. The front helped to drop temperatures from 5°F to 12°F, but little to no rainfall was associated with it.
