What happened
The episode as NWS AMA wrote it up.
On the evening of the 28th of August a severe thunderstorm formed on the New Mexico/Texas State Line near Nera Visa, NM as a line of thunderstorms approached from the west. These thunderstorms did not maintain or gain strength as they entered the Texas Panhandle. However the thunderstorm that formed out ahead of the line on the state line managed to gain enough strength to put out a wind gust of 58 MPH. The line of thunderstorms did come into the northwest combined Oklahoma/Texas Panhandles but quickly became less organized with no severe characteristics.
What forecasters said that day

.AVIATION...00z TAF Cycle...
Isolated to scattered thunderstorms have formed near KGUY with
storms also moving toward KDHT. Storms may stay just north of
KGUY, so have VCTS but will watch for amendments. A tempo group
was added for KDHT to try to pin down most likely time for storm
impacts there. Confidence too low at this time to include any
thunder mention at KAMA. Some shower or storm activity could
linger into the night, but most of the activity should shift east
of the terminals by 06z or so. A cold front will move through the
area overnight with gusty winds picking up out of the north. Some
MVFR/IFR cigs are also possible behind the front, favoring KGUY
and KDHT. These stratus could linger well into the morning on
Saturday. Another round of storms could form Saturday afternoon,
so have PROB30 groups in for that potential.

.PREV DISCUSSION... /Issued 202 PM CDT Fri Aug 28 2020/
SHORT TERM...
Mid to upper level high pressure currently sits over NM, eastern
AZ, and west to southwest TX. Today temperatures are supposed to
get into the triple digits with some places even breaking records
this afternoon. Over night tonight slight troughing will form over
the Panhandles northward to the Panhandle of NE pushing the
current high pressure south and slightly to the west.
Perturbations in the flow aloft will allow for some thunderstorms
this evening and tonight mainly in the northwest combined
Panhandle to start, then mainly the OK Panhandle over night. At
the same time a surface cold front will push through, making it to
Amarillo around midnight or slightly before. Winds are expected
to pick up to around 30 mph out of the northwest around portions
of the northwest TX Panhandle with 20 to 25 mph else where behind
the front.
Temperatures tomorrow afternoon will be cooler behind the front
with temperatures in the 80s for the northern combined Panhandles
and 90s in the southern TX Panhandle. Surface winds will become
more northeasterly around 10 to 15 mph in the afternoon. Another
shortwave trough will move through tomorrow night helping to spark
off more showers and thunderstorms this time covering a greater
area of the combined Panhandles. A decent amount of monsoonal
moisture at H7 will move up through NM entering the Panhandles
from the west. PWAT values will be approaching the 90th percentile
for late August. Looking at MLCAPE values, the NAM is the only
model that is NOT suggesting any severe weather for tomorrow
afternoon, as it shows all the CAPE just south of the CWA along
the frontal boundary. All the other models have MLCAPE right
around 1000 J/KG across the Panhandles, even behind the front.
Wide spread severe weather will not be likely but cannot rule out
an isolated severe storm with the system late tomorrow afternoon
into the evening.

LONG TERM...Sunday through Thursday...
After one more day with temperatures above average, we will start
the coming work week with temperature below average, along with
the chance of precipitation.
Ahead of a cold front moving through the Panhandles early next
week, one more day of temperatures well into the 90s to around 100
degrees is expected with south to southwest sfc winds advecting
H850 temps of 30-32C. A perturbation will move east across the
Panhandles giving a slight chance for storms. Although instability
looks to be elevated Sunday into Sunday night, watching the timing
of a cold front to the north may help to trigger some surface lift
as the front begins to move south late Sunday night. Cannot rule
out a strong to severe thunderstorm, especially across the east
with large hail and damaging wind gust the main threat.
Northerly to northeasterly flow behind the front will work its way
south across the Panhandles during the day on Monday. Temperatures
behind the front will be quite cool compared to what we have been
seeing in the past several weeks.High temperatures will range
from upper 70s to the north to mid 80s to the south. A pronounced
perturbation will move equatorward across the Rockies towards the
Sangre de Cristos by Monday evening. As this main upper level
perturbation moves southeastward Monday night into Tuesday, large
scale ascent across the Panhandles should increase chances of
precipitation across the Panhandles. The developing H500 low
pressure system lee of the Rockies along with 2nd push of cooler
airmass behind front will move south through the Panhandles
Tuesday night into early Wednesday morning. Any residual
precipitation according to the latest 28/12Z model and numerical
guidance should diminish greatly past sunrise Wednesday morning
with some leftover precipitation possible in the far eastern
Panhandles. Large scale H500-300 subsidence will diminish
precipitation chances going towards the end of the long term
forecast period.
Behind the cold front Tuesday and Wednesday, temperatures will
still be slightly below average. Southeasterly flow should return
by Thursday which will moderate temperatures back to slightly
above average for early September.
