Public Information Statement
Statement as of 1:28 PM CDT on August 1, 2015

... Very dry conditions developed across southeast Texas in July...

Note... corrections were made to the year-to-date rainfall and the
June rainfall.

The month of July continued the dry trend that had developed in
the last part of June. With the drier conditions came also very
warm temperatures. July ended with much below normal rainfall and
with slightly above normal temperatures across southeast Texas.

Two out of the 12 first- and second-order climate sites recorded
rainfall above an inch. All of the remaining sites received under
three quarters of an inch. The average rainfall for all 12 sites
was 0.68 inches... much below the area-wide normal of 4.00 inches.
Here is a table comparing each climate site for the July rainfall...
the January and February dry period... the March through may wet
period... and the month of June.

The rainfall departures for each site reveals some interesting
data. Galveston and Palacios at the coast has had a fairly dry
year. Otherwise... a very wet March... April... an especially wet
month of may... and a mixed above and below normal June led to some
very wet conditions which then led to the ending of the drought
across southeast Texas. With a near to slightly drier than normal
June to now a very dry July... abonrmally dry conditions were
developing across portions of southeast Texas.

The following table lists the preliminary monthly temperature and
rainfall data for the first- and second-order climate sites across
southeast Texas. Note that very warm conditions were reported...
with each site showing above normal monlthy average daily
temperatures.
