Texas Climate Report: June 2010

June 2010 was drier than normal across most of Texas, though there were a few distinct regions that received above normal precipitation for the month. A storm system on the 9th and 10th dumped several inches of precipitation in region stretching from Austin/San Antonio northeastward to Texarkana. This same storm system was responsible for several flooding deaths at a campground in Arkansas. College Station picked up 4.27" of precipitation on the 9th and extensive flooding was reported along Guadalupe and Comal Rivers in Central Texas. Tyler picked up 8.14" on the 10th and 8 to 12 inches of rainfall caused extensive damage to homes and washed out roadways in Hill and Navarro counties. Severe thunderstorms in the Panhandle on the 13th dumped over 6 inches of rain in Hansford County and in Moore County, a storm dropped a massive 6-inch hailstone that was caught on video. Toward the end of the month, a tropical system that eventually became Hurricane Alex formed in the Gulf of Mexico and threatened the Lower Texas Gulf Coast. Alex made landfall on the evening of the 30th in northern Mexico as a Category 2 hurricane with 105 mph winds. Hurricane Alex’s most significant impact was excessive rainfall, which led to flooding on South Padre Island. On the 30th, McAllen set a daily rainfall record for the entire month of June with 6.66" of rainfall, while Brownsville recorded 5.86" of precipitation, setting a 24-hour rainfall record for June. In addition to the flooding rains in the Lower Valley, several tornadoes were reported and one of the twisters overturned a mobile home.

Temperatures across all of Texas were above normal across the entire state. Dallas/Fort Worth was particularly hot, tying 2008 as the 3rd warmest June on record and was just half a degree cooler than June 1980, which was the beginning of most severe heat wave in the history of the Metroplex. Averaged over the entire month, minimum temperatures in DFW were the warmest ever recorded in June. San Angelo was also unusually warm, with average temperatures nearly 6°F above normal and maximum temperature nearly 7°F above normal during June. A historically hot stretch of weather brought extreme summer heat to West Texas during the first week of June, well before the official start of summer.

Midland also set a record on the 5th with a high temperature of 109°F and El Paso set new record high temperatures on the 5th (106°F) and 6th (110°F), the latter of which was 5°F warmer than the previous record).
