Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

Area Forecast Discussion
National Weather Service San Angelo TX
1200 AM CDT Sun Apr 12 2020

.AVIATION...
/06Z TAFS/

Scattered to numerous showers and thunderstorms will continue to
develop across the area overnight. Included VCTS at all sites,
with most convection ending by 12Z. In addition, patchy MVFR
ceilings will be possible. West winds will increase to 15 to 25
knots, with higher gusts, by mid morning. A cold front will move
through the area Sunday evening, resulting in north winds of 10 to
20 knots with higher gusts.

&&

.PREV DISCUSSION... /issued 629 PM CDT Sat Apr 11 2020/

AVIATION...
/00Z TAFS/

Chances for brief thunderstorms this evening for most terminals,
followed by another round between 04-08Z. VFR outside of
thunderstorms. Rapid wind shifts expected in and during
thunderstorms with large hail and strong winds possible.
Thunderstorm threat ends by 12Z, but strong winds expected through
the day.

SK

PREV DISCUSSION... /issued 328 PM CDT Sat Apr 11 2020/

SHORT TERM...
(Tonight)

.Severe Thunderstorms...

Look for thunderstorms this afternoon and tonight, as another
upper disturbance moves over the region. The Storm Prediction
Center has all of West Central Texas in an Enhanced Risk Area,
through sunrise Sunday morning. The main hazards are tornadoes,
very large hail, damaging winds, and deadly lightning.

(Sunday)

.Breezy and Another Cold Front...

As another cold front, this one unusually strong for mid April,
moves closer to West Central Texas, gusty winds, from the west,
will develop Sunday. Then, the cold front may begin to move into
the Big Country, by mid afternoon. Although this front will be a
dry front, it will bring gusty winds from the north, along with
uncharacteristically cold temperatures, for mid April.

LONG TERM...
(Sunday night through Saturday)

.Much Cooler Temperatures then a Warmup...

Much cooler temperatures will dominate through mid week, before a
warming trend begins. Overnight lows Monday night, likely in the
mid to upper 30s, will be unusually cold, for mid April. Plus, the
wind chill Monday night, may be in the mid to upper 20s. Cooler
than usual temperatures will continue until Wednesday; then, a
warming trend will push temperatures back above usual mid April
temperatures for Friday and Saturday.
