What happened

The episode as NWS AMA wrote it up.

While many places improved in drought conditions leading up to September, a several counties across the Texas and Oklahoma Panhandle continued to experience severe drought (D2) conditions while a small area in the southwest Texas Panhandle remained in extreme drought (D3) status. Only one day of rain occurred in September, however it was enough to keep some areas from degrading with regard to drought status. The most common impacts were limited range land grasses for ranchers and lost crops to farmers. Also, some farmers were not able to start planting winter wheat at the end of the month due to the lack of soil moisture.

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.

NWS Amarillo, TX wrote its last area forecast discussion before the first event at Aug 31, 5:47 PM CST, 6 hours 13 minutes earlier.

.AVIATION...
A few thunderstorms may try to develop after about 10Z tonight
near AMA. At this point, do not have enough confidence in this
happening to add to the TAF. Thunderstorms may develop in the
central Texas Panhandle again Tuesday afternoon. Again, confidence
in a thunderstorm affecting the AMA TAF site is low, so will not
mention at this time. Skies are expected to remain VFR outside of
thunderstorms and winds are expected to remain around 10 knots or
less, except for DHT which should see a little bit stronger wind
behind a cold front around mid day on Tuesday.

.PREV DISCUSSION... /Issued 258 PM CDT Mon Aug 31 2020/

SHORT TERM...Tonight through Tuesday Night...

West to southwest flow aloft will bring in some lingering moisture
overrunning the surface cold front. Isolated showers/storms possible
this evening, but very little instability expected, therefore no
severe weather is anticipated.

Cutoff low expected to eject from the upper level trof and drop over
the Four Corners region tomorrow afternoon.  This in conjunction
with the stalled retreating cold front will put the Panhandles in
the moist sector tomorrow afternoon and evening.  Lee surface low to
set up and provide a dryline interaction.  Warm moist air in the low
levels and decent jet aloft with the right entrance region setup
over head will allow for scattered to widespread severe storms to
develop.  Now, if the surface trof pushes further east quicker than
expected, we could be completely shut down for the majority of the
central and western Panhandles. But for now all hazards are in play
for all the Panhandles, except for the northern OK Panhandle, and
northeast OK/TX Panhandle.  The tornado threats currently very low,
but not a non-zero threat, and it's set for the southern Panhandles,
with Amarillo in play.  A lot could change and we'll continue to look
at our threats and collaborate with SPC for any changes to the
severe outlook for tomorrow.

LONG TERM...Wednesday through Saturday...

Tuesday through Thursday, models are depicting a shortwave trough
with a cutoff low over NM. This will continue some rain chances
through Wednesday and possibly into Thursday night depending on
the eastward progression of this system. The ECMWF has the slowest
progression of all the solutions. By Thursday morning H5 high
pressure starts to build over CA and NV. The sooner the cutoff low
can leave the FA the sooner this high will build into the area.
The NBM has been giving some chance PoPs into Friday. Have been
leaning towards slight-chance PoPs due to the high uncertainty of
the system. Have thus far, lowered PoPs slightly, but as to still
maintain some continuity with surrounding forecast offices.

There will be a decrease in temperatures on Wednesday from a
frontal passage Tuesday night. Thursday temperatures will be
slightly above normal with highs in the low 90s and upper 80s.
Another cold front will move through Thursday night cooling
Friday's daytime temperatures down to near normal. Depending on
how the rain pans out on Friday, there could be a dry period
Saturday through Sunday then PoPs return on Sunday night with only
a slight chance.

Cimarron County continued to have an 8 to 12 inch rainfall deficit with the hardest hit area being the northwest half of the county. The county saw minimal rain, on the first of the month allowing for conditions to not deteriorate further, but amounts were not enough to improve conditions. Biggest impacts from the drought conditions all year thus far is no range land grasses for cattle. Farmers have been having to rely solely on irrigation depleting aquifers.
