The radar

The Ft Hood radar (KGRK), 113 km from the middle of the area, began a volume at 09:08 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

Fort Worth, TX (KFWD), launched 00:00Z, 9.1 hours before the alert went out and 256 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.

NWS Austin/San Antonio, TX wrote its last area forecast discussion before this flash flood warning went out at Jul 13, 1:03 AM CDT, 3 hours 3 minutes earlier. Its key messages:

A dangerous risk with potential of high impact flash flooding is forecast for later tonight into Sunday
Level 3 of 4 risk of excessive rainfall for the rest of tonight into Sunday morning for parts of the southern Edwards Plateau and Hill Country; a Level 2 of 4 risk along the I-35 corridor and/or near the Rio Grande
Rainfall amounts of 2 to 4 inches with isolated 9 to 12 inches possible across the Flood Watch area through Sunday evening
Rapid river rises are anticipated with this dangerous flash flooding event

.KEY MESSAGES...

- A dangerous risk with potential of high impact flash flooding is
  forecast for later tonight into Sunday

- Level 3 of 4 risk of excessive rainfall for the rest of tonight
  into Sunday morning for parts of the southern Edwards Plateau and
  Hill Country; a Level 2 of 4 risk along the I-35 corridor and/or
  near the Rio Grande

&&

.SHORT TERM...
(Today through Monday)
Issued at 1254 AM CDT Sun Jul 13 2025

A dangerous risk with the potential of high impact flash flooding
event is unfolding late tonight into Sunday. Various meteorological
features are forecast to come together to create heavy rain rates (2
to 4 inches/hr) leading to flash flooding and rapid river rises. The
complex of storms is likely to slowly push to the southeast from the
San Angelo area as abundant Gulf moisture feeds into the convergence
zone (line of storms). This is a dangerous situation since we
already had a significant heavy rain event last week with soils near
to saturation or at saturation levels. Runoff will take over quickly
making rivers to rise to dangerous levels in addition to flash
flooding across poor drainage and low-lying areas and low water
crossing. Hires models are in good agreement with tonight's heavy
rainfall event and therefore, our confidence is medium to high as
far as occurrence and locations. With that said, higher rainfall
amounts are expected through the Flood Watch period with 2 to 4
inches and isolated 9 to 12 inches possible.

There is a good chance that the Flood Watch gets extended and
expanded on Sunday with new data suggesting for heavy rain to
continue Sunday evening into Monday morning as a mesoscale
convective vortex lingers around the Hill Country. For now, we are
concentrating for the late tonight into Sunday morning period.

&&

.LONG TERM...
(Monday night through Saturday)
Issued at 1254 AM CDT Sun Jul 13 2025

For the extended forecast period, relatively dry and warm conditions
are expected mid to late week with high temperatures at seasonal
values for most of the work week and reaching the mid to upper 90s
by next weekend.

&&

.AVIATION...
(06Z TAFS)
Issued at 1254 AM CDT Sun Jul 13 2025

MVFR cigs return overnight across the local area terminals and stay
through mid morning on Sunday. We are expected heavy rain overnight
into Sunday morning across the Hill Country, southern Edwards
Plateau, and Rio Grande. At this time, this activity should stay to
the north and northwest of the airports. By mid to late Sunday
morning into the afternoon period, rain chances and thunderstorm
probabilities increase for the I-35 sites and KDRT. Stronger storms
could produce heavy downpours and reduced visibilities. A southeast
to south wind flow is forecast to dominate during this forecast
cycle with speeds around 6 to 12 knots and gusts up to 22 knots .
