Aided by drought, a heat wave persisted in late Summer 2000 along the southern tier of the United States from July to early September of that year. Near the end of the period, daily, monthly, and even all-time record high temperatures were broken, with highs commonly peaking well over 100 degrees Fahrenheit. On September 4, Houston hit 109 F and Dallas peaked at 111 F[1]; on September 5, Austin, Texas [2] and San Antonio peaked at 111 F [3] while College Station reached 111 F on both the 4th and 5th of September [4].
