What happened
The episode as NWS AMA wrote it up.
Showers and thunderstorms developed across the Oklahoma Panhandle and northwest Texas Panhandle this afternoon in close proximity to a surface boundary coupled with steep lapse rates from triple digit temperatures and some low level moisture and|associated atmospheric instability. Due to rather large surface temperature and dewpoint spreads along with corresponding high downdraft CAPE, storms developed and produced damaging wind gusts across the central OK Panhandle and the northeast TX Panhandle through the early evening hours on the 19th.

National Weather Service Amarillo TX
1226 PM CDT Thu Jul 19 2018
.AVIATION...
VFR conditions are expected throughout the 18Z TAF period. Some
weather model guidance does show the possibility of an isolated
thunderstorms, especially at KDHT starting a few hours after the
start of the TAF period. Confidence is too low to include in
forecast at this time but will make amendments when necessary.
Otherwise, sct mid and high clouds will continue into tomorrow
morning and then slowly begin to clear out. Winds will be out of
the south at 5-10 kts, then shifting to more southwesterly at
10-15 kts towards the end of the TAF period.

PREV DISCUSSION... /Issued 429 AM CDT Thu Jul 19 2018/
DISCUSSION...
Hot weather can be expected through Sunday as mid-level ridge
remains over the southern Plains and southern Rockies. Isolated
thunderstorms are forecast this afternoon and this evening across
the northwest half of the forecast area. Instability will be
maximized across northern sections and northwest flow aloft could
direct thunderstorms into western sections from the higher
terrain. Steep mid-level lapse rates and well-mixed lower air
(which should be drier today compared to recent days) will set the
stage for strong downdrafts and little in the way of measurable
rain.
Similar setup expected on Friday, although instability expected
to be maximized in northern sections. Nearby frontal boundary
over southern Kansas may become active and direct outflows into
our northern zones which could serve as convergence zones for
convection.
Saturday and Sunday expected to be dry as very warm mid-level
temperatures suppress convection. Cold front Monday brings
chances for thunderstorms through Tuesday and "cooler" conditions
through Wednesday.
