The radar

The Midland/Odessa radar (KMAF), 202 km from the middle of the area, began a volume at 02:51 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

Del Rio, TX (KDRT), launched 00:00Z, 2.8 hours before the alert went out and 187 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.

- Near record high temperatures are expected today. Temperatures

.SHORT TERM...
(This afternoon through Saturday night)
Issued at 133 PM CDT Fri Sep 4 2026

The heat continues going into this weekend for west Texas and
southeast New Mexico as upper-level ridging builds back into the
Great Plains. However, today looks like the hottest day of the
forecast period, and temperatures cool very gradually going into the
Long Term. Highs once again top out near or just above 100 degrees
across the area today, with low to mid 90s in and around the higher
terrain. Lows tonight bottom out in the low-to-mid 70s for most.
Similar to yesterday, isolated to scattered showers and
thunderstorms are expected to develop this afternoon and evening.
While the best chances (20-40%) will be south and west of the Pecos
River (especially in the higher terrain), low chances (10-20%) are
maintained elsewhere thanks to lingering moisture and lift on the
western edge of Edouard's remnants.

Even though ridging continues to build westward Saturday, relatively
lower heights over our area yield temperatures a degree or two
cooler than today's. Highs in the mid-to-upper 90s will be
commonplace, with 100 degree temperatures becoming more confined to
the river valleys. Lows Saturday night end up similar to tonight's.
Isolated to scattered showers and thunderstorms will develop again
tomorrow afternoon and evening, but this time will remain mainly
south and west of the Pecos, with a few sneaking into the western
Permian Basin (20-40% chances for these locations). For both today
and tomorrow, storms that develop may produce heavy rainfall, strong
winds, and frequent lightning.

.LONG TERM...
(Sunday through Thursday)
Issued at 133 PM CDT Fri Sep 4 2026

By early next week, a trough moving across northern portions of the
CONUS helps push the ridge back to the east. As a result, we will
see temperatures decrease a couple of degrees more around this
timeframe, though they will remain about 4-8 degrees above normal
for this time of year. Highs through at least the middle of next
week end up in the mid-to-upper 90s for most locations, with upper
80s and low 90s in/around the higher terrain. Low rain chances
(10-30%) stay pretty close to the higher terrain through at least
the middle of next week as well. As far as the latter portion of
the forecast goes, there remains some inconsistency in the models
as to where the ridge will be positioned, how strong it will be,
and therefore what our rain chances and temperatures will look
like going into next weekend. At this time, the NBM maintains very
low PoPs for portions of the area (10-20%). Meanwhile, both the
GFS and Euro have started to depict the ridge building back
towards the Plains by the end of the week. As a result,
temperatures have trended a bit higher across the area, such that
most locations are now forecast to see highs in the mid-to-upper
90s throughout the week.

.AVIATION...
(00Z TAFS)
Issued at 611 PM CDT Fri Sep 4 2026

Isolated to scattered storms have developed across much of the
region this afternoon. Highest confidence in storms impacting
terminals will be at MAF and FST early this evening. Brief MVFR
VIS and erratic, gusty winds are expected with any storm. Outflow
boundaries will also bring brief gusty and variable winds through
this evening. By 03Z, a low-level jet develops across portions of
the Permian Basin and Lower Trans Pecos increasing southeasterly
winds through 06Z. Otherwise, VFR conditions and light
southerly/southeasterly will prevail through the period.
