Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
1144 PM CST TUE DEC 22 2015

.AVIATION...
HIGHLY VARIABLE CONDITIONS WILL BE OBSERVED AT ANY GIVEN TIME AT
THE TERMINALS OVERNIGHT AND EARLY WEDNESDAY MORNING. HOWEVER...THE
PREVAILING CONDITIONS WILL BE MVFR AND IFR DUE PRIMARILY TO
CEILINGS. THE BEST CHANCE FOR RAIN THROUGH THE EARLY MORNING WILL
BE KGPT...KASD...KMSY AND KHUM WHERE CONVECTION MAY ALSO BE
OBSERVED. THE WINDS WILL REMAIN UP OVERNIGHT...SO SIGNIFICANT FOG
IS LESS OF A THREAT TONIGHT. TIMING OF RAINFALL IS RATHER
UNCERTAIN ON WEDNESDAY...BUT IT APPEARS THAT THE BEST CHANCE OF
MORE WIDESPREAD RAIN DURING THE COURSE OF THE DAY MAY BE OVER THE
EASTERN AND SOUTHERN AREAS OF THE FORECAST AREA. HOWEVER...THE
BEST CHANCE OF STRONGER CONVECTION WILL LIKELY BE OVER THE
NORTHERN AND WESTERN SECTIONS OF THE FORECAST AREA. MVFR CEILINGS
WILL DOMINATE DURING MUCH OF THE DAY WEDNESDAY. 11
