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 severe thunderstorm 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.

What forecasters said that day

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

NWS Corpus Christi, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at May 10, 12:16 AM CDT, 2 hours 56 minutes earlier.

Area forecast discussion, May 10, 12:16 AM CDT, 2 hours 56 minutes before

Area Forecast Discussion

1216 AM CDT Fri May 10 2019

.DISCUSSION...

See aviation discussion below for the 06Z TAFs.

&&

.AVIATION...

This TAF cycle will be noted with mostly MVFR conditions for low
ceilings. Thunderstorms are making their way out of the forecast
area, so we should have a break in rainfall through parts of this
cycle. KVCT is just now (05Z) getting a relief from a complex of
thunderstorms exiting to the east. Need to watch for redevelopment
later today, especially along the outflow boundary currently south
of KCRP. Chances are sites may come close to IFR conditions at
times, especially later today if thunderstorms redevelop.
Thunderstorms could be severe at times as well with heavy
rainfall, gusty winds, and hail all possible. Otherwise, wind
speeds should be mostly from the north/northeast behind the front
with low clouds sticking around for most of the cycle.
