Texas Climate Report: September 2007
September 2007 was a warm month across the entire state. In fact, every first-order station recorded an above average monthly mean temperature. A persistent ridge of high pressure anchored over the southeastern United States was the main culprit for the warm temperatures. In all, 7 of the 20 first-order stations recorded departures from normal of at least 3°F for monthly mean temperature. Dallas/Fort Worth and Galveston recorded their 10th warmest Septembers on record, with monthly mean temperatures of 81.6°F and 83.0°F, respectively. Houston recorded its 8th warmest September on record with a monthly mean temperature of 81.9°F. Despite the warm temperatures, only one station (Amarillo) recorded a maximum temperature in the triple digits.
Precipitation patterns were varied across the state. The area stretching from roughly the South Plains through the extreme western Hill County to the western Coastal Bend recorded below average rainfall for the month. Abilene and Midland only recorded 42% and 54 % of their normal rainfalls, respectively, while San Antonio recorded only 36% of its normal rainfall total. Most of North Texas, including Waco, Dallas/Fort Worth, and Wichita Falls, received above average rainfall totals. Southeast Texas rainfall totals were varied. Houston and College Station received below average rainfall, while Galveston and Port Arthur received above average totals. Port Arthur recorded 5.56" of rainfall on the 12th-13th in association with Hurricane Humberto.
The main weather story of the month was the impact of Hurricane Humberto on the Upper Texas Coast. Humberto formed into a tropical depression on the morning of September 12th and quickly gathered strength. The storm moved parallel along the Upper Coast Texas and quickly intensified into a tropical storm. Humberto made landfall as a category 1 hurricane near High Island, TX on the early morning hours of the 13th. Maximum sustained winds at landfall were 85 mph. Port Arthur recorded maximum sustained winds of 56 mph and gusts of greater than 84 mph. Damage from the storm was confined to far eastern portions of Southeast Texas. Humberto was the first hurricane to make landfall along the Upper Texas Coast since Hurricane Rita in 2005.
