The radar

The San Angelo radar (KSJT), 99 km from the middle of the area, began a volume at 03:53 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.

.KEY MESSAGES...

- Strong to severe storms possible this afternoon through tonight,
  and some risk for flash flooding tonight.

- Unsettled and potentially active pattern continues Sunday
  through Friday of next week with a severe weather risk Sunday
  through Wednesday, and daily chances of showers and storms
  through the week.

.SHORT TERM...
(This evening through Sunday)
Issued at 215 PM CDT Sat Apr 11 2026

An approaching shortwave in southwest flow aloft will help to
initiate thunderstorm development in the TX Big Bend and
southwest Texas, into the Pecos Valley and portions of the Permian
Basin this afternoon into the evening. Out ahead of this
shortwave, scattered showers and storms are expected over our area
in a moist and unstable airmass. With CAPE values expected to
increase to 1000-1500 J/KG, the strongest storms will be capable
of producing large hail and localized strong or damaging winds.
Expect storms west and southwest of our area to increase in
coverage by this evening. Larger clusters of thunderstorms will
overspread at least the western half of our area between 8 PM and
Midnight, and the eastern and southeastern parts of our area after
Midnight. With storms tonight, the main severe weather threat
will be strong/possibly damaging winds, especially with any bowing
line segments. There is a very low (2 percent) threat for an
isolated tornado this evening and tonight.

With precipitable water values increasing to around 1.5 inches,
heavy rain will accompany the convection. Overall, rainfall
amounts around 1 inch will be common, with areas under heavy
downpours receiving totals of 2 to 4 inches. A few higher totals
will be possible. While widespread rain will be beneficial for the
area, heavy rainfall concentrated in short periods of time (also
backbuilding storms) could cause flooding of city streets, low
water crossings and and other poor drainage areas. Quick rises on
some area streams and rivers will be possible tonight into Sunday
morning, especially in areas with hilly terrain. Expect showers
and storms to be over our eastern (Heartland) and southeastern
counties in the early to mid- morning hours Sunday, before ending.

After morning cloud cover on Sunday, coverage will decrease from the
west by afternoon. This should allow for the airmass to have enough
time to recover and become moderately unstable. Mid-level southwest
flow will be strong enough to support a severe weather threat
(mainly large hail and damaging winds) should any storms develop.
However, there is considerable uncertainty in this time on the
extent of development and storm coverage. Expect highs Sunday
afternoon to range from the upper 70s/near 80 in our southeastern
counties, to the mid 80s across a good portion of the Big Country
and Concho Valley.

&&

.LONG TERM...
(Sunday night through next Saturday)
Issued at 126 PM CDT Sat Apr 11 2026

Southwest flow aloft will transition to zonal flow toward next
weekend. The main weather concerns begin with the approach of an
upper low over the 4 corners region Monday night, which brings in
chance of showers and thunderstorms. The better chance of storms,
however, will be Tuesday afternoon/evening and again Wednesday...as
storms develop off a dryline in the Permian Basin and moving east.
With a warm moist air mass with dew points in the lower to mid 60s,
there will be the potential for severe weather each day next week,
although Thursday and Friday looks less conducive for severe
weather. While its quite far out and confidence is low at this time,
shower and thunderstorm chances could increase again next weekend,
with approach of a weak front Saturday and a slightly stronger front
Sunday.

Over all, warm temperatures prevail next week with highs mainly in
the low to mid 80s, and overnight lows in the lower to mid 60s.

&&

.AVIATION...
(00Z TAFS)
Issued at 637 PM CDT Sat Apr 11 2026

Main concern will a line of strong/possibly severe convection
late this evening and overnight. Mainly VFR conditions through
mid to late evening, with scattered showers and a few
thunderstorms, mainly at KSJT and KABI. A strong line of storms
is expected to develop and moves east across the terminals late
this evening/overnight. Gusty winds and heavy rainfall will be the
main concern but some hail is also possible. Will continue with a
TEMPO groups for the line of storms and PROB30 groups for
lingering convection once the line passes. Stratus with MVFR/IFR
ceilings are expected towards daybreak through the morning hours.
Expect mainly light southeast to south winds overnight, except
erratic and gusty in and around convection.
