Texas Climate Report: August 2005

The month of August had its ups and downs for the state of Texas. The first half of the month was a cooler and wetter than in the past, at least for most of the state. A strong convective system moved through Central Texas on the 9th and 10th. Waco received 2.69" during a three day stretch (8th-10th) and was 9°F cooler than average on the 9th and 10°F cooler on the 10th. College Station received 1.92" on the 10th with high winds reported in the area. The panhandle of Texas had a long stretch of days in which the temperatures were below average, including two days in Abilene where the average temperature was over 10°F below normal. On the 14th the average temperature in Amarillo was 14°F below normal. During this same time period Wichita Falls was receiving immense amounts of rainfall. In a four day period, 13th through 16th, the city received 6.96" of rainfall, with one 24-hour total at 4.55" (the normal monthly rainfall amount is 2.39"). The DFW area received 2.44" over two days (14th-15th). El Paso also received its fair share of the rainfall and cooler temperatures. On the 12th it rained 2.26" in the city, where the normal monthly rainfall total is 1.27", and the average temperature was 10°F below normal. The second half of the month, however, seemed exceedingly different.

Starting around the 16th the state became hot and dry. In many areas, including College Station, Austin, DFW, Waco, and Lubbock, rain was non-existent for all but the last days of August and while no records were broken, it was very hot with highs hovering around the century mark for many days, but many of these cities got off easy when compared to South Texas. Just a note of interest, Austin Camp Mabry was 0.13" above average while Austin Bergstrom was 0.94" short. What a difference a small distance can make.

South Texas, including Corpus Christi and McAllen, was hot and dry for all of August. The rains that cooled off the state in the beginning of the month missed South Texas and no rain seem to fall in this area for the entire month. Corpus Christi received only 0.25" of rain, a vast deficient of 3.29" short of the month normal total. Not only was Corpus dry but it was also the hottest August on record, which only added insult to injury. Brownsville also had its hottest August on record. South Texas is also very dry, with Brownsville 8.66" below normal for the year and Corpus Christi 7.45" below normal.
