... Hot and dry conditions returned in September 2016...

Southeast Texas experienced a very warm September. Most of the
reporting climate and coop sites recorded below normal rainfall for
the month as well. The warmth was punctuated by nine temperature

Records either tied or set at three of the first-order climate sites.
Locations that experienced exceptions to the drier than normal
conditions were mainly west of Interstate 45 and along the Highway
59 corridor to the coast.

September saw the first-order sites experience one of the top 5 to
15 warmest months on record. Here are some of the outstanding "warm"
facts for September 2016.

* note that data for College Station incorporates both Easterwood
Field since 1951 and the coop site from 1903 to 1951.


Although daily high temperatures did reach into the mid and upper
90s for part of the month, another reason for the warm daily average
temperatures were very warm temperatures at night. The following
table illustrates just how warm the overnight and early morning lows
were across the area. One caveat for the city of Houston is that the
temperature sensors moved from downtown to Intercontinental Airport
in 1969. Note that these rankings do not include coop sites and that
some of the following airports only have records back to the 1990s.

1951 and the coop site from 1903 to 1951

Most of the climate sites recorded a rainfall deficit of around 1 to
4 inches. Two exceptions were Clover Field in Pearland (+1.84 inches)
and Palacios (+0.95 inches). Even with the deficits, the year-to-date
rainfall was still very much on the plus side and ranged from +4.94
at Palacios to +26.47 at dw Hooks Airport. However, the U.S. Drought
monitor did not record any developing drought across the area in
September. This can be attributed to the very wet conditions which
occurred in August.

There were nine daily records set at the first-order climate sites.
Six of these were set at hobby Airport, with eight of the nine being
record high minimum temperatures. The following is a listing of the
records tied or set in September at College Station (cll), Galveston
(gls), and hobby Airport (hou). Houston (iah) did not experience any
record events.
