The radar

The Lubbock radar (KLBB), 132 km from the middle of the area, began a volume at 22:18 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Midland Regional, TX (KMAF), launched 12:00Z, 10.3 hours before the alert went out and 176 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

...New SHORT TERM, LONG TERM...

.KEY MESSAGES...
Updated at 242 PM CDT Thu May 21 2026

- Isolated to scattered showers/storms continue through this evening
  across the Permian Basin and Lower Trans Pecos. A storm or two
  may be strong to severe, posing a threat for localized flash
  flooding, damaging winds, and large hail.

- Daily afternoon/evening storm chances through next week, with
  locally heavy rainfall possible.

&&

.SHORT TERM...
(This afternoon through Friday night)
Issued at 242 PM CDT Thu May 21 2026

Rain chances remain in the forecast during the Short Term period. A
few storms have developed over the Permian Basin ahead of a dryline
extending from eastern NM south toward the Big Bend. Some of these
may produce large hail, damaging winds, and localized flash
flooding. Storm activity gradually begins to diminish and shift
eastward this evening, with rain chances mostly ending around, or
just after midnight. Temperatures then slip into the 50s and 60s
tonight.

Friday afternoon, the dryline sets up within the western Permian
Basin, extending down toward the Big Bend. Meanwhile, additional
shortwave impulses will continue to pass over our region, embedded
within a large-scale trough over the western US. As such, isolated
shower/storm development will be possible over the eastern Permian
Basin and the Lower Trans Pecos, where rain chances range from 10-
20%. Given drier conditions and sunnier skies overall, temperatures
Friday afternoon are generally expected to top out in the upper 80s
to mid 90s. Overnight lows again range within he 50s to 60s, with
60s being more prevalent than the night before.

&&

.LONG TERM...
(Saturday through Wednesday)
Issued at 242 PM CDT Thu May 21 2026

Upper level troughing persists over the western and central US at
the start of the Long Term period. Sunday into Monday, a closed low
develops within the mid levels and sets up over Texas. Several
rounds of shortwave impulses look to traverse over our area through
the next few days. At the surface, the dryline also looks to
oscillate near to within our region through at least the middle of
next week. Lift from both the shortwaves and along the dryline shall
combine with moisture ahead of the dryline to support at least
isolated shower/storm development most afternoons. Storm development
and location will depend on collocation of forcing from shortwaves
and the dryline. As such, there remains high uncertainty regarding
forecast rainfall totals and the potential for severe weather
heading into the upcoming week. Temperatures are progged to range
within the 80s to 90s across the region each afternoon, then dip
into the 50s and 60s during the overnight hours.

&&

.AVIATION...
(18Z TAFS)
Issued at 242 PM CDT Thu May 21 2026

Scattered TS is currently moving east of the terminals though more
is expected to develop later this afternoon. Only enough
confidence for PROB30 at MAF/FST though TS is also possible at INK
and PEQ. Expect mostly SHRA/TS with LTG and gusty and erratic winds
the main threats. IFR/MVFR conditions have either become VFR or
will become VFR very shortly and should remain VFR outside of any
showers. Light mist lowering VIS to 3-5SM is possible near 12Z but
not included in the forecast due to low confidence.
