Texas Climate Report: July 2004

Texas was split during the month of July as the Gulf coast experienced warm, dry weather, and the remainder of the state was wet and colder than normal. During the first week, a series of frontal systems brought some rain to the Panhandle and northern border of the state. Hail as large as 3" was reported in Cottle County on the 1st, and Wichita Falls received 1.96" of precipitation on the 6th. A high pressure system settled over the state during the second week and temperatures soared across the state. Abilene, Dallas, Del Rio, El Paso, Lubbock, Midland, San Angelo, and Wichita Falls all topped 100°F during the first half of July. The stretch of summer weather continued until the end of the third week when a shortwave trough moved across the northern part of the state. Temperatures dropped as a cold front slowly moved eastward – highs on the 24th and 25th only reached the 60s and 70s for many stations in west Texas including: Abilene (70°F), Amarillo (65°F), Lubbock (64°F), and Wichita Falls (73°F). During this same time, Amarillo, College Station, and Midland received at least an inch of precipitation. A stationary front over North Central Texas produced heavy rains in many counties. Dallas (4.14") and Waco (4.94") nearly doubled their normal monthly precipitation on the 28th-29th, while Wichita Falls added another 1.96" and Lubbock received 2.05".

For the month, all but four first-order stations had below-normal temperatures with the coldest averages in the north and central portions of the state. South, East, and South Central Texas all experienced a very dry month with the exception of Victoria. Houston (25%), Galveston (25%), Brownsville (22%), and Shreveport (18%) received less than a quarter of their normal July rainfall. Out west, El Paso saw its fifth consecutive month with above-normal precipitation. Also, the heavy rains at the end of the month helped College Station, Dallas, Lubbock, and Waco record above-normal precipitation for the month.
