What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Lubbock, TX wrote its last area forecast discussion before this special weather statement went out at May 31, 2:32 AM CDT, 13 minutes earlier.

Area forecast discussion, May 31, 2:32 AM CDT, 13 minutes before

Area Forecast Discussion
National Weather Service Lubbock TX
232 AM CDT Mon May 31 2021

.SHORT TERM...
At 2 AM, an eastward-moving MCS across the eastern South Plains
and the Rolling Plains was beginning to merge with a southeastward-
moving MCS exiting the southeastern Panhandle. This combined MCS
will move east through the remainder of the overnight hours,
likely exiting the forecast area to the east around the beginning
of Day 1 at 12Z. While the severe threat has waned, heavy rainfall
remains possible. Focus then shifts to the potential for
thunderstorm redevelopment later today. An upper level trough
remains in place from Nebraska to northern Baja with a series of
shortwaves ejecting from the base of the trough over northern
Mexico east-northeastward across West Texas. The next in this
series is expected to result in convective initiation as early as
mid to late morning across southeastern New Mexico with a general
movement to the east. The mesoscale evolution will be key for both
severe and flooding potential as a pair of outflow boundaries are
currently in play. The outflow from the South Plains MCS has moved
southward into the Permian Basin, although behind the boundary
across the western South Plains and adjacent areas of eastern New
Mexico, winds have veered toward southeast. However, that may be
disrupted by the second outflow boundary, this one emanating from
the Panhandle MCS. Hi-res models seem to be in generally good
agreement with a final confluent area near or just south of the
boundary between the LUB and MAF forecast areas. Even if the
boundary ends up south of the LUB forecast area, enough elevated
instability is expected to exist to result in up to about 2000
J/kg of CAPE and would continue to support both a severe and heavy
rain threat. Will continue with high PoPs as lift increases later
this morning with a severe and flooding focus across the southern
two rows of counties. As a result will extend the Flood Watch for
those two rows through the afternoon. Low level focus for
additional convective development this evening to overnight should
begin to shift further south as reinforced outflow shifts southward
and cooler air mass across the forecast area gets a bit deeper.
Thus, will see a gradual decrease in both rain chances and rain
amounts as the night progresses.

.LONG TERM...
The base of the upper trough to our west is progged to cut off
over Baja California by midweek with the remainder of the upper
trough expected to shift slowly eastward toward the Mississippi
Valley. Meanwhile, an amplifying ridge over the West Coast will
begin to expand eastward toward the Great Plains late in the week.
The resultant north/northwest upper flow Tuesday and Wednesday
over the Rockies to West Texas will bring the potential for high
terrain diurnally-driven storms to make it into the forecast area
both days. The expanding ridge will likely bring a relative lull
in precipitation chances on Thursday, but the cutoff low will
finally open up and move slowly eastward as the ridge expands. Its
movement toward and across the forecast area is expected to bring
another uptick in precip chances Friday through the weekend.
Cooler than normal temperatures continue to look a good bet through
most, if not all, of the forecast period, although a trend from
well below to below is expected as rain chances and amount of
cloud cover begin to decline.

1151 AM CDT Sun May 30 2021

This Hazardous Weather Outlook is for the South Plains, Rolling
Plains and the far Southern Texas Panhandle.

.DAY ONE...This afternoon and tonight.

A line of thunderstorms, some severe, is expected to occur late this
afternoon into the evening and affect the extreme southern Texas
Panhandle, South Plains, and Rolling Plains. Heavy rainfall is
expected. Rain rates within thunderstorms may locally exceed two to
three inches per hour at times which will lead to a high threat of
flooding, especially given the recent rainfall over the last week
across the region.

Damaging wind gusts up to 60 mph and large hail up to golf ball size
will be possible initially, with the hail threat confined to
isolated thunderstorms that form in the late afternoon. After
thunderstorms form into a line, the main hazards will be flooding
and localized damaging winds.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.

Widespread thunderstorms are expected Monday and Monday night.
Decreasing instability will bring a decreased threat for severe
weather. However, isolated strong thunderstorms could become
marginally severe or produce locally heavy rainfall.

Thunderstorm chances will continue Tuesday through Saturday, and
these storms will bring a risk for severe weather each day.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed.
