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
Slidell Radar S, LA (KSIL), launched 00:00Z, 1.0 hours before the alert went out and 41 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.

SHORT TERM...
THUSFAR...THINGS HAVE BEEN GOING ACCORDING TO FORECAST WITH
COPIOUS RAINS IMPACTING THE FORECAST AREA...PARTICULARLY ACROSS
THE METRO NEW ORLEANS AREA. THE THREAT STILL CONTINUES FOR AN
ADDITIONAL 2 TO 4 INCHES OF RAINFALL FROM A PRONOUNCED TROPICAL
PLUME THAT EXTENDS WELL INTO THE GULF OF MEXICO AND RECENTLY HAS
BEEN ENHANCED BY FRONTAL INTERACTION. THERE REMAINS A LARGE AND
PERSISTENT AREA OF RAINFALL FROM THE I-55 CORRIDOR WESTWARD TO THE
COLD FRONT THAT IS MOVING THROUGH THE ALEXANDRIA AREA AT THIS
TIME. WILL MAINTAIN ALL WATCHES AND ANTICIPATE ISSUANCES OF FLOOD
WARNINGS DURING THE EVENING HOURS AS THE HEAVY RAINS RETURN. COLD
FRONT EXPECTED TO MOVE INTO BATON ROUGE AREA AROUND 00Z THEN
CONTINUE INTO THE NEW ORLEANS AREA AROUND 03Z. THERE REMAINS SOME
UNCERTAINTY ON ENDING THE RAINFALL AS THE MODELS SHOW THE UPPER
SUPPORT COMING TO A HALT NEAR THE ARKLATEX WHICH WOULD DIMINISH
THE FORWARD MOMENTUM OF THE SURFACE FRONT. WE ARE BASING THE
FORECAST ON THE FRONT MAKING IT THROUGH THE FORECAST AREA BUT THE
POST FRONTAL ASPECTS MAY BE DICEY FOR TUESDAY AND WEDNESDAY.
LONG TERM...
EXPECTING JUST A GRADUAL WARMING TREND THROUGH SEASONABLE
TEMPERATURES ONCE THE DEFORMATION WRAP-AROUND CLOUDINESS ABATES IN
THE WAKE OF THE SHORT-TERM FRONT. DID NOT SPEND TOO MUCH TIME OR
EFFORT ON THE EXTENDEDS GIVEN THE MORE DIRE OPERATIONS IN THE
SHORT-TERM BUT BLENDING WELL WITH NEIGHBORS.
AVIATION...
MOST CEILINGS AND VISIBILITIES IN THE MVFR RANGE OUTSIDE OF
PRECIPITATION. NUMEROUS SHOWERS AND THUNDERSTORMS WILL PRODUCE
CEILINGS AND VISIBILITIES DOWN TO THE LIFR CATEGORY ON OCCASION
THROUGH SUNRISE. SQUALL LINE LIKELY TO IMPACT BTR AROUND 00Z...MCB
AROUND 02Z...MSY 03-04Z AND GPT 06-08Z. 35/RSW

WILL CONTINUE SMALL CRAFT ADVISORY THROUGH TONIGHT. WHILE CURRENT
WINDS SLIGHTLY BELOW CRITERIA...SEAS STILL AROUND 6 FEET...AND
STRONGER WINDS TO THE WEST. HAVE NOTED GUSTS INTO GALE RANGE JUST
OFF TEXAS COAST. WITH FRONT GRADUALLY EXPECTED TO SLOW DOWN...EXPECT

AT 230 PM CDT...A LARGE AREA OF MODERATE TO HEAVY RAINFALL BLANKETED MUCH OF SOUTHEAST LOUISIANA EAST OF THE ATCHAFALAYA RIVER AND SPREADING INTO MISSISSIPPI. AN AXIS OF VERY HEAVY RAINFALL EXTENDED FROM NEW IBERIA SOUTHWARD INTO THE CENTRAL GULF OF MEXICO...AND MOVING TOWARD SOUTHEAST LOUISIANA. THIS WILL BRING ANOTHER ROUND OF POTENTIALLY FLOODING RAINS INTO AREAS THAT EXPERIENCED FLOODING EARLIER TODAY. IN LOCATIONS THAT HAD NOT RECEIVED MUCH RAINFALL THIS MORNING...HEAVY RAINS CAN BE EXPECTED UNTIL THE COLD FRONT MOVES THROUGH THE AREA. SOME THUNDERSTORMS WERE DEVELOPING AND AT TIMES WERE EXHIBITING ROTATING CONDITIONS...PARTICULARLY IN EAST-CENTRAL LOUISIANA NEAR THE MISSISSIPPI STATE LINE. THERE IS STILL A CHANCE FOR A FEW STORMS TO BECOME SEVERE PRIOR TO COLD FRONTAL PASSAGE. THE COLD FRONT WAS SITUATED BETWEEN DERIDDER AND ALEXANDRIA AND HAD MOVED THROUGH SHREVEPORT AND LAKE CHARLES ALREADY. IT CONTINUES TO MOVE TO THE EAST AT AROUND 30 MPH. BRISK NORTHWEST WINDS WITH GUSTS TO 40 MPH WERE OCCURRING WITH THE FRONTAL PASSAGE IN WEST LOUISIANA. THE FRONTAL PASSAGE WILL BRING AN END TO THE FLOODING RAINS AND SEVERE THUNDERSTORM THREAT. MEANWHILE...EVERYONE IS URGED TO REMAIN ALERT TO THE WEATHER SITUATION THROUGHOUT THE AFTERNOON AND EVENING. ADDITIONAL FLOODING IS POSSIBLE AND ALL PREPARATIONS TO MINIMIZE FLOOD DAMAGE IS ENCOURAGED. HEAVY RAINS MAY IMPACT THE EVENING COMMUTE...SO PLAN ACCORDINGLY TO SEEK ALTERNATIVE ROUTES AND ALLOW FOR ADDITIONAL TIME TO REACH YOUR DESTINATION. ANY UNNECESSARY TRAVEL SHOULD BE POSTPONED UNTIL CONDITIONS IMPROVE. 24
