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.

The nearest sounding before it

Shreveport, LA (KBAD), launched 12:00Z, 3.9 hours before the alert went out and 154 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.

Area forecast discussion, May 23, 5:25 AM CDT, 5 hours 27 minutes before

Area Forecast Discussion
National Weather Service Shreveport LA
525 AM CDT MON MAY 23 2016

.AVIATION...
Vfr conditions with mostly cirrus clouds will prevail for most of
the day across the region. Some low mvfr to ocnl ifr decks
sneaking into ne tx in deep sw flow, and dense fog developing
around the KLFK terminals...with vsbys falling below 1/4 sm.
Outflow boundaries from stg bowing convection movg eastward along
and just south of red river valley, may result in sct aftn
redevelopment of tstms possibly affecting mainly KTYR,KGGG, and
KTXK portions of area this aftn. S-SE winds around 10 kts expected
this aftn. Deepening southerly flow may bring low clouds across a
greater portion of CWA after 24/08z./vii/.

&&

.PREV DISCUSSION... /issued 237 AM CDT MON MAY 23 2016/

DISCUSSION...
A thunderstorm complex across southern Oklahoma contributing to
high clouds across the region this morning. High clouds should
dissipate later this morning with temperatures forecast to climb
into the mid 80s areawide.

Southwest flow aloft will provide for increased moisture across
the region through the work week. Partly to mostly cloudy skies to
prevail with a chance of afternoon showers and thunderstorms each day.
There is a marginal risk of strong to severe thunderstorms today
mainly across East Texas, Southeast Oklahoma, portions of
Southwest Arkansas and portions of Northwest Louisiana as weak
impulses translate northeast along mean flow.

An upper-trough across the west coast will swing east and deepen
into a closed low across the desert southwest by midweek. The low
will shift east across the Texas Panhandle on Thursday night
allowing for increased instability across the Arklatex on Friday.
With sufficient moisture in place, some storms could become severe
on Friday.

Afternoon showers and thunderstorms to continue on Saturday and
Sunday.

Otherwise...light south to southeast winds to prevail through the
forecast period with high temperatures ranging from highs in the
80s to lows around 70 each day.
