...Dry conditions continued in August over most of southeast Texas...

The month of August 2014 ended up on the dry side and with near normal temperatures at most of the climate sites across southeast Texas. Those first- or second-order sites which received over one inch of monthly rainfall experienced these amounts during one of three episodes.

A cold front brought cooler than normal conditions and sporadic rainfall during the first week of the month. The second week started out warm but then ended with another cold frontal passage that brought some rainfall. The mid month period experienced very warm conditions as the subtropical ridge build overhead. August ended with the ridge breaking down and an upper level low pressure area bringing scattered thunderstorms and cooler than normal temperatures.

The climatological Summer defined as the months of June...July...and August has come to an end. There were no 100 degree days recorded at any of the four first-order climate sites during this period. Houston has not had a Summer free of 100 degree days since since 1997 and College Station has not achieved this feat since 2004. The average temperature for the Summer was also cooler than normal for areas north of I-10 and a bit warmer than normal for areas south of of I-10. The following table gives the 2014 Summer average temperature along with the 30-year average temperature and departure as a comparison for the four first-order climate sites.

Even with the sporadic rain events...dry conditions continued over most of southeast Texas as all but three of the climate sites recorded below normal rainfall. Deficits ranged between -1.21 and -4.33 inches. The sites which experienced above normal rainfall were Galveston /+.56 inches/...Sugar Land /+2.99 inches/...and Angleton /+0.54 inches/. As of August 26th...abnormally dry to moderate drought conditions were reported by the U.S. Drought monitor generally along and west of a line from Snook to Wallis to Sargent. The following table gives a few more details...
