Texas Climate Report: May 2006

May 2006 was truly in like a lion but out like a lamb. Storms and severe weather plagued the state for the first week. From the 1st through the 5th there were 28 tornado reports, 68 strong wind reports, and 286 hail reports. The 5th proved to be the day with the most violent weather. On that day alone there were 82 hail reports, 20 severe wind reports, and 18 tornadoes. A very strong bow-echo squall line moved on a northwest-southeast line from Lubbock through Waco and on into College Station. Martin and Burnet counties reported four tornadoes each. A F2 tornado touched down in Waco, producing damage to many businesses along Franklin Avenue. McLennan County also had a wind speed of 87 mph reported. The 14th was the last day for any severe weather to impact the southeastern regions of the state. For the remainder of the month, the storms were confined to West Texas as the dryline initiated storms which produced mainly high winds, with a few reports of hail, and 3 reports of tornadoes on May 29th. A strong ridge set in over the southern United States, which increased the temperatures and prevented rainfall over the state.

Temperatures were above average for all of the state. Temperatures around the coast were about 1.5°F above normal. Temperatures in Central Texas were about 2°F above normal, while temperatures in West Texas were around 4°F above normal. Record highs were set in many locations across the state. San Angelo reported record highs of 102°F on the 13th and the 20th. Corpus Christi reported a record high temperature of 103°F on the 10th, which broke the old record by 8°F! Brownsville and San Antonio reported record highs of 99°F and 97°F, respectively, on the 10th. Austin and San Antonio reported record highs of 97°F and 98°F, respectively, on the 27th. The average departure for normal for the entire state was 2.8°F.

Some relief finally came at the end of the month as a upper-level trough lifted the moist air along the coast and produced heavy precipitation. On the 29th Houston reported 4.33" and Victoria reported 5.39", which were both record daily precipitation totals. Corpus Christi reported 3.06" on the 31st. The last four days of the month provided much needed rainfall for the South Central, Southern, and Lower Valley regions of Texas.
