The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
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 (KBAD), launched 12:00Z, 1.6 hours before the alert went out and 144 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 SHREVEPORT LA
507 AM CST FRI DEC 25 2015
.DISCUSSION...
WAVY COLD FRONT DRAPED OVER THE ARKLATEX FROM NEAR LUFKIN...TO
NEAR SHREVEPORT...TO NEAR EL DORADO WITH A NW WIND. THE SFC WINDS
ARE LIGHT N/NW OVER SE OK/SW AR/NE TX WITH A 10 TO 13 DEGREE
SPREAD EDGING INTO LONGVIEW NOW. ELSEWHERE LIGHT TO PATCHY DENSE
FOG IS HERE AND THERE WITH UPPER 60 AND LOW 70 DEW POINTS. RADAR
IS SHOWING MOST OF THE SHOWER AND THUNDERSTORM ACTIVITY RIGHT
ALONG THE BOUNDARY. ALOFT...AN UPPER SHORT WAVE IS SEEN ON THE
WATER VAPOR WITH A KNIFE LIKE DRY SLOT INTO ST LOUIS...AND BACK
ACROSS TEXARKANA...TO AUSTIN TX. THE MID LEVEL DRIER AIR WILL HELP
TO KEEP PRECIP TRENDING ACROSS OUR EAST.
THERE IS LITTLE CHANGE AS THE OLD FRONT HOLDS NEARLY STATIONARY
UNTIL TOMORROW WHEN A MUCH DEEPER STORM...NOW OVER THE FOUR
CORNERS...EDGES OUT IN OVER THE PLAINS. THIS WILL KICK OUR
SOUTHERLY WINDS IN GEAR AND PUSH THE WARM FRONT QUICKLY TO THE
NORTH ALONG THE I-30 CORRIDOR. MOST OF THE RAIN WILL REDEVELOP ON
THE NEW APPROACHING COLD FRONT AS IT SLOWLY WORKS SOUTHEASTWARD
OVER THE FOUR STATE AREA OVER THE NEXT FEW DAYS. THE SPC HAS US IN
AND OUT OF A MARGINAL AND DAY TWO WILL EDGE A SLIGHT RISK INTO OUR
AREA PRIOR TO EXPIRATION ON 27/12Z. THE MODELS REMAIN VERY
CONSISTENT NOW ON THE BOWLING BALL LOW MOVING RIGHT OVER SE OK AT
12 ON MONDAY WITH CLOSE HEIGHTS WITHIN A HANDFUL OF DM WITH A
TIGHT CLOSED LOW. 2 TO 4 FOR MOST WITH SOME 6 TO 10 INCH QPF
LIKELY AS THIS FEATURE BOTTOMS OUT IN THE PATTERN RIGHT OVER HEAD.
THE WPC 5 DAY OUTLOOK HAS A 10.79 BULLSEYE IN E OK. THE RAIN WILL
CUT OFF QUICKLY IN THE WAKE OF THE PASSAGE AND DRIER AIR WORKS IN
FROM THE NORTHWEST. THE STRONG COLD FRONT WILL THEN BRING BACK
WINTER FOR A GOOD WHILE AS A 1027MB SURFACE HIGH PRESSURE BUILDS
IN OVER THE AREA. /24/
