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.

What forecasters said that day

The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS San Angelo, TX wrote its last area forecast discussion before this tornado warning went out at May 8, 6:26 PM CDT, 27 minutes earlier.

Area forecast discussion, May 8, 6:26 PM CDT, 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
626 PM CDT Fri May 8 2015

.AVIATION...
/00Z TAFS/

Thunderstorms may affect KABI this evening as a thunderstorm
outflow boundary sinks slowly southward. Otherwise MVFR stratus
will return this evening along the I-10 corridor and spread
north after midnight to KSJT and eventually KABI. Stratus should
rise to IFR late morning to early afternoon. Isolated to scattered
afternoon thunderstorms possible Saturday but low confidence on
timing, so did not include in terminals.

&&

.PREV DISCUSSION... /ISSUED 429 PM CDT Fri May 8 2015/

SHORT TERM...
(Tonight and Tomorrow)

..Severe Thunderstorms...

The potential for severe thunderstorms highlights the forecast
for the next 24 hours. With southwest flow aloft over Texas and a
dryline to our west, severe thunderstorms are possible during the
next 24 hours. Most of our Counties are currently under Tornado
Watch number 145, which continues until midnight CDT tonight. In
addition, the 0 to 6 kilometer bulk shear this afternoon is in
the 40 to 60 knots range; plus, surface based CAPEs this afternoon
are around 4000 J/Kg. These conditions clearly have our attention.
With ongoing severe thunderstorms to our northwest, outflow
boundaries from that activity will be a big player, during the
evening hours, for supercell initiation over our counties.

LONG TERM...
(Saturday night through Friday)

..Severe Weather Threat Into Sunday Night...

With the main focus on the short term, the long term forecast
remains essentially unchanged. The upper trough axis will finally
move over and east of our counties Sunday night. Until then, any
thunderstorms, which develop over or move into our counties, may
be severe. The timing of the next front looks more likely for early
to mid day Monday, rather than late Sunday night. Temperatures
after the front still look cooler, at least into mid week. Another
developing upper trough, along the west coast, will help maintain
southwest flow aloft over Texas for most of next week. Thus,
thunderstorms remain in the forecast for all long-term periods.
