The radar

The Holloman AFB radar (KHDX), 29 km from the middle of the area, began a volume at 21:18 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, 9.3 hours before the alert went out and 361 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.

Updated at 957 AM MDT Sun Aug 16 2026

 - Storm activity expected to begin in the Sacramento Mountains
   mid-day before reaching the El Paso/Las Cruces area later in
   the afternoon.

 - Marginal risk for excessive rainfall this afternoon/evening,
   and storm-generated outflows with gusty winds up to 40 mph

 - Best storm chances on Monday will be in the Sacramento
   Mountains and Gila National Forest, posing a risk for flash
   flooding in the mountains. Dry, hot weather returns to lowlands
   by midweek.

.DISCUSSION...
Issued at 957 AM MDT Sun Aug 16 2026

The combination of an approaching upper-level low from the
southeast, daytime heating, orographic lift, and increased moisture
will provide the setting for another round of afternoon/evening
convection today. A few storms have already developed over both the
Sacramento mountains and the Gila National Forest with the activity
forecast to transition into the El Paso/Las Cruces area later in the
afternoon. Localized flooding remains a concern, as max rainfall
amounts from CAMS range between 1-2 inches, but as to who will get
hit the hardest in the lowlands is still inconclusive at this time.
The Gila National Forest and Sacramento Mountains will see the best
chance for heavy rain this afternoon. Models and soundings are
showing downdraft CAPE values of around 1000J/kg, and are indicating
that thunderstorm generated outflows may produce gusty winds up to
40 mph, which could stir up blowing dust for the lowland deserts
this afternoon.

By Monday, the upper-level low will be sheared off from the
subtropical high, but some low to mid-level moisture will remain
over southern New Mexico. The Gila National Forest will see the best
chance (50-60%) for heavy rain and localized flooding Monday
afternoon, with the Sacramento Mountains coming in second (25-35%).
Southeastern Hudspeth County may also see some isolated
thunderstorms Monday afternoon, while the rest of the lowlands have
a minimal chance for rain. That being said, PWAT values in the
lowlands are still hovering around 1.2-1.3 inches for Monday, so the
threat of localized heavy rain cannot be ruled out.

The ridge starts to return overhead on Tuesday, drying the lowlands
out and raising temperatures back to the triple digit mark mid- to-
late week. Still a chance of some relief later in the week as the
ridge's eastern flank breaks down.

&&

.AVIATION...
(18Z TAFS)
Issued at 957 AM MDT Sun Aug 16 2026

Another round of showers and thunderstorms is in store this
afternoon. While flying conditions will generally be VFR for the
period, the threat of heavy rain and outflow winds from 22Z to 03Z
could lower visibilities to 5SM for all four TAF sites, straddling
the line between VFR and MVFR depending on where thunderstorms
initiate. All TAF sites have a 30% chance for storms, and
thunderstorm activity will dwindle after 03Z, with only high BKN
250 ceilings and light winds remaining overnight.

&&

.FIRE WEATHER...
Issued at 957 AM MDT Sun Aug 16 2026

Continued rain will keep ERC values on the low side early this
week, but ERC values will increase by midweek. Min RHs will be
above 20% across the region today and tomorrow on the account of
the best thunderstorm chances today being in the Rio Grande Valley
and in the Gila National Forest on Monday. Localized heavy rain
and gusty winds will be the main hazards with these storms. Drier
air will begin to move in on Tuesday. Lowland min RH values will
fall to the teens and stay in the 20s in the mountains.
Ventilation rates today and tomorrow will range from good to very
good.
