The radar

The Ft Hood radar (KGRK), 90 km from the middle of the area, began a volume at 20:42 UTC, the scan nearest the moment this went out.

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 12:00Z, 8.7 hours before the alert went out and 238 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.

Continued unseasonably wet and "cool" into Monday.
Turning seasonably drier and warmer next week.

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

.KEY MESSAGES...

- Threat of Flash Flooding from slow moving and repeat heavy
  rains this evening. A Flood Watch remains in effect for the
  Hill Country and I-35 corridor through 10 PM CDT.

- Continued unseasonably wet and "cool" into Monday.

- Turning seasonably drier and warmer next week.

.SHORT TERM /THROUGH SUNDAY NIGHT/...
Issued at 250 PM CDT Sat Jul 5 2025

A mid level MCV and unusually moist airmass continue move
across our CWA. Forcing by this feature will generate rounds of
showers and isolated thunderstorms. Storm motion will be slow.
The tropical nature of the airmass is leading to efficient warm
rain processes. As a result, locally heavy rain will be possible
this evening. New rainfall of 1 to 3 inches with isolated
amounts up to 5 inches is possible. This rain will aggravate
ongoing flooding and likely create new flooding as soils are
saturated making runoff more rapid. The heaviest rains will be
over the Hill Country to along and east of the I-35 Corridor
this evening. A Flood Watch is now in effect until 10pm. Most
models show the rain shifting to our western areas Sunday.
Models are showing lower rainfall totals for Sunday. The clouds
and rain areas will conspire to keep daytime temperatures below
to well below normal.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 250 PM CDT Sat Jul 5 2025

The mid level feature may remain close enough to our CWA to
generate isolated showers and isolated Monday. The airmass will
remain moist and there will be a possibility of locally heavy
downpours. Most models/ensembles show the subtropical ridge
pushing the mid level feature away from our area while bringing
increased subsidence and decreasing moisture. This will keep
rainfall out of the forecast for the remainder of this coming
week. However, the GFS shows an inverted trough moving in from
the east which could bring chances of showers and isolated
thunderstorms Tuesday and Wednesday. This solution is not in the
NBM and thus not in our forecast. Later forecasts may introduce
rain chances should this become a trend. Increased sunshine will
lead to temperatures warming to near or slightly above averages.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
(18Z TAFS)
Issued at 250 PM CDT Sat Jul 5 2025

Isolated TSRA with scattered to widespread RA continues across the I-
35 corridor, with decreasing trends in TS coverage observed over the
last 6 hours. CIGs range from MVFR to IFR within this activity but
are expected to gradually lift to VFR with isolated MVFR this
afternoon. Due to uncertainties in TS activity later today, have
maintained a PROB30 at AUS where thunder likelihood is slightly
higher than at other terminals. Expect a return of MVFR to IFR CIGs
overnight after 08Z near and over the I-35 terminals, expanding to
DRT closer to 14Z. CIGs should recover after 16Z-18Z, but timing and
rate of improvement is low confidence due to significant model
uncertainties in handling the disturbance associated with the
current shower activity over the area.
