... 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...
