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
Jackson, MS (KJAN), launched 12:00Z, 11.7 hours before the alert went out and 122 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
NATIONAL WEATHER SERVICE NEW ORLEANS LA
317 PM CDT SAT MAY 30 2015
.SHORT TERM...
A HIGH CAPE...LOW SHEAR ENVIRONMENT IN PLACE. THERE IS A WEAK
UPPER LEVEL TROUGH OVER LA AND MS THIS AFTERNOON. AT THE SURFACE
HIGH PRESSURE RIDGE DOMINATES THE AREA.
.LONG TERM...
THE UPPER LEVEL TROUGH WILL GRADUALLY STRENGTHEN AND ACT AS A
FOCUS FOR MORE NUMEROUS THUNDERSTORMS...ESPECIALLY DURING THE DAY
LIGHT HOURS WHEN CONVECTIVE HEATING IS AT ITS MAXIMUM. PART OF
THE UPPER LEVEL TROUGH COULD GET CUT OFF AND LINGER OVER LA...AR
AND MS MONDAY THROUGH WEDNESDAY BEFORE IT WEAKENS AND MOVES TO
AL..TN BY THURSDAY. THE FORECAST AREA WILL BE DOMINATED BY A
BUILDING UPPER LEVEL RIDGE IN THE WEST LA AND THE SLOWLY
RETREATING UPPER LEVEL TROUGH IN MS AND AL LATER DURING THE WEEK.
THIS PATTERN WILL HELP LIMIT THE NUMBER OF THUNDERSTORMS AND BRING
WARMER MAXIMUM TEMPERATURES. HOWEVER...WILL HAVE TO MONITOR
THUNDERSTORM POTENTIAL LATER IN THE WEEK...SINCE ANY THAT FORM
WILL BE GOOD WET MICROBURST CANDIDATES.
&&
.AVIATION...
CUMULUS FIELD RATHER EXTENSIVE ACROSS THE CWA TERMINALS THIS
AFTERNOON. GENERALLY VFR CONDITIONS AT FORECAST ISSUANCE TIME. RADAR
SHOWS ISOLATED CONVECTION RANDOMLY DOTTING THE AREA. ANY ORGANIZED
CONVECTION IS STILL SEVERAL HOURS WEST OF THE ATCHAFALAYA
RIVER...AND NOT EXPECTED TO REACH LOCAL TERMINALS THIS AFTERNOON.
EXPECT MUCH OF THIS ACTIVITY TO DISSIPATE WITH SUNSET. VFR
CONDITIONS EXPECTED FOR MOST OF THE NIGHT. SOME MVFR VSBYS POSSIBLE
AT KMCB AROUND SUNRISE ON SUNDAY. ISOLATED SHOWERS AND THUNDERSTORMS
SHOULD BEGIN REFIRING BY ABOUT 15Z SUNDAY...BECOMING A LITTLE MORE
NUMEROUS DURING THE AFTERNOON HOURS. AS HAS BEEN THE CASE THE LAST
COUPLE DAYS...BRIEF MVFR TO IFR CONDITIONS POSSIBLE WITH THE
STRONGER STORMS...GUSTS TO 30 KNOTS OR SO AS WELL. 35
&&
.MARINE...
LIGHT EAST TO SE WINDS WILL REMAIN OVER THE COASTAL WATERS
THROUGH THE FORECAST. ISOLATED TO SCATTERED THUNDERSTORMS WILL BE
POSSIBLE EACH DAY. SOME NOCTURNAL SHOWERS SHOULD ALSO DEVELOP EACH
NIGHT THROUGH MID WEEK. 17/35
