What happened

The episode as NWS SHV wrote it up.

An upper level ridge of high pressure built back in across portions of the Southern Plains and Lower Mississippi Valley on July 28th, with compressional warming occurring ahead of a weak surface front as it moved slowly south across Eastern Oklahoma and Central Arkansas. This resulted in high temperatures climbing into the upper 90s to near 100 degrees across East Texas. Low level moisture pooled north ahead of the front over East Texas, Southeast Oklahoma, Southwest Arkansas, and North Louisiana, with these temperatures, combined with the high humidity, resulting in heat indices between 105-109 degrees across much of Northeast Texas.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area Forecast Discussion...UPDATED
National Weather Service Shreveport LA
1158 PM CDT Thu Jul 27 2017

.AVIATION...
VFR conditions should continue through the 28/06Z TAF period. An
extensive cirrus shield will linger over much of the region
overnight, with the potential for a weak IFR/low MVFR stratus
shield to develop around 12Z over portions of Deep E TX
(near LFK)/Wcntrl LA before lifting by mid-morning. Meanwhile, sct
convection should remain N of the region overnight/through much of
Friday as additional redevelopment continues over Ern OK/Ncntrl AR
near a weak sfc front and old outflow bndry over these areas. Have
removed VCSH/VCTS mention for the TXK/ELD terminals, with the
threat delayed until the evening/overnight hours Friday night,
mainly over SE OK/SW AR which may possibly migrate into portions
of extreme NE TX/N LA. However, confidence remains low with the
highest confidence attm being over Scntrl AR closer to the sfc
front as it enters this area by 00Z Saturday. Thus, have inserted
VCTS mention at 00Z for ELD, although additional mentions may be
needed elsewhere should the convection develop/drift closer to the
remaining terminals. S winds 3-7kts tonight will become WSW around
10kts after 15Z. /15/

.PREV DISCUSSION... /issued 1003 PM CDT Thu Jul 27 2017/

DISCUSSION...
A quiet evening will manage much of the night with debris cirrus
aloft. Our temperatures are still ranging in the 80s with only a
couple of upper 70s. Thats where most of us will end up by
daybreak with a couple mid 70s maybe. No changes to going
forecast as HRRR does show spotty QPF by 12Z in our North, we will
keep the slight chance wording in place and await the front
tomorrow night and hopefully a good wetting rain areawide. /24/
