July 2012

Print Email

The month of July varied greatly depending on where in the state one lives. Those lucky enough to live in the southeastern portions of the state saw temperatures below normal for the month as well as higher than normal precipitation. Big Bend saw approximately average rainfall and temperatures for the month while the rest of Texas came in above normal in temperatures and below normal in rainfall. North Texas and the Panhandle saw the brunt of summertime with all areas reporting two degrees Fahrenheit or more above average as well as 50% or less of average precipitation.

This lack of rainfall brought back some severity in the drought for Texans north of Interstate 20, where the Panhandle saw the widespread return of severe drought and Dallas-Fort Worth saw the return of drought conditions. This dry and hot weather was attributed to a high pressure system which is typical of summertime in Texas. This ridge kept the rain out and the heat in for the majority of the month. Southeast and Central Texas fared much better this month than usual, mainly due to a stationary front that persisted in and around the Houston Metro area from July 11th to the 13th. Cities affected by this system reported record 24-hour rainfall totaling nearly 5.5 inches in some places, more than the rainfall attributed to Hurricane Ike in 2008. This helped to boost all of Southeast Texas out of drought conditions altogether.
