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.

The nearest sounding before it

Shreveport, LA (KSHV), launched 00:00Z, 0.0 hours before the alert went out and 91 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.

 - Scattered to numerous showers and thunderstorms, some strong to
   severe will be possible across most of the Four State Region

.DISCUSSION...
Issued at 1145 AM CDT Sun May 10 2026

A shortwave trough will move southeast out of New Mexico this
afternoon, eventually pushing through the ArkLaTex late this
evening. The upper-trough will phase with a surface boundary
across central Texas this afternoon. A moist surface airmass along
and east of the frontal boundary along with ample daytime heating
will further aid in destabilizing the environment with lapse
rates forecast to steepen areawide. Thunderstorms are forecast to
develop along the front at the time of peak heating across Texas
and begin shifting eastward toward the ArkLaTex through this
evening. Models generally agree that a bowing convective complex
could be pushing into east and northeast Texas late in the evening
with severe weather possible. Hail and damaging winds will be the
highest threats along with an isolated tornado threat. However,
outflow boundaries resulting from ongoing convection across north
Texas could stabilize the atmosphere enough across portions of
northeast Texas, southeast Oklahoma and portions south Arkansas to
mitigate a widespread organized severe weather risk prompting SPC
to remove these areas from the Day 1 slight risk outlook.

Severe threat to wane overnight with lingering showers and
isolated thunderstorms possible through mid-morning Monday as the
upper-trough finally translates east across the region.
Conditions to improve through Monday afternoon with upper-level
northerly flow becoming established across the Southern Plains.

Cool surface high pressure expected to build areawide on Monday
with afternoon high temperatures in the mid 70s. Overnight low
temperatures Monday night are forecast to average in the 50s.
Otherwise, upper-level ridge to build across the region allowing
for a warming trend with high temperatures late in the workweek
approaching 90 degrees in some areas. /05/

.AVIATION...
(00Z TAFS)
Issued at 648 PM CDT Sun May 10 2026

Most sites are near or at VFR cigs at the beginning of this
period before the next push of lower cigs moves in from the
northwest with the next round of rain. There may be some embedded
thunder with this line, but severe potential should be lower once
night falls. The frontal passage driving these showers are likely
to keep winds elevated apart from a few eastern sites, but low
ceilings should keep fog development at bay. Expect brief
worsening conditions in pockets of heavier rainfall. Showers are
expected to move eastward as cigs lift late tomorrow morning and
into the afternoon hours. /57/

&&

.SPOTTER INFORMATION STATEMENT...
Issued at 1145 AM CDT Sun May 10 2026

Strong to severe thunderstorms will be possible Today through
at least this evening. Therefore, spotter activation will likely
be needed during this timeframe.
