The radar
The Houston radar (KHGX), 148 km from the middle of the area, began a volume at 23:04 UTC, the scan nearest the moment this went out.

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 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.
The nearest sounding before it
Lake Charles Mun, LA (KLCH), launched 12:00Z, 11.0 hours before the alert went out and 242 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, Dec 12, 4:44 PM CST, 17 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
444 PM CST SAT DEC 12 2015
.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
AN ACTIVE SHORT TERM PERIOD ON TAP FOR SOUTHEAST TEXAS... WITH
PERIODS OF SHOWERS AND THUNDERSTORMS EXPECTED NOW THROUGH THE
OVERNIGHT HOURS BEFORE A SQUALL LINE AND ASSOCIATED COLD FRONT MOVES
ACROSS THE REGION. PRESENTLY... INCREASING SOUTHERLY FLOW AND WARM
AIR ADVECTION AHEAD OF AN APPROACHING DISTURBANCE OVER ARIZONA IS
RESULTING IN WIDESPREAD SHOWER DEVELOPMENT ALONG AND NORTH OF
HIGHWAY 59 THIS AFTERNOON. THIS ACTIVITY WILL SERVE AS THE FIRST
OF TWO ROUNDS OF SHOWERS AND THUNDERSTORMS ACROSS THE REGION.
FOR THE REMAINDER OF THE AFTERNOON AND EVENING... EXPECT
INTERMITTENT PERIODS OF SHOWERS AND THUNDERSTORMS TO CONTINUE.
WILL NEED TO KEEP AN EYE ON AN ISOLATED SEVERE THUNDERSTORM
THREAT... PRIMARILY FOR DAMAGING WINDS AND ISOLATED TORNADOES
GIVEN THE AMOUNT OF WIND SHEAR PRESENT. SPC MESOANALYSIS SHOWS 0-1
KM SHEAR VALUES RANGING FROM ANYWHERE BETWEEN 15 TO 30 KNOTS AND
THIS WILL ENCOURAGE STRONG LOW LEVEL ROTATION. CONTINUING TO
MONITOR CELLS DEVELOPING ALONG AND WEST OF INTERSTATE 45 AS THIS
LOCATION HAS BEEN A FAVORED AREA FOR ROTATING CELLS THIS
AFTERNOON. THE SECOND ROUND IS EXPECTED TO BEGIN EARLY SUNDAY
MORNING AS A SQUALL LINE APPROACHES THE REGION FROM THE WEST. THIS
SQUALL LINE IS EXPECTED TO APPROACH THE WESTERN COUNTIES BEFORE
SUNRISE SUNDAY MORNING... REACH THE INTERSTATE 45 CORRIDOR MID-
MORNING... AND CLEAR THE EASTERN COUNTIES BY MIDDAY SUNDAY. GUSTY
WINDS WILL ALSO BE POSSIBLE ALONG THE LEADING EDGE OF THIS LINE...
AND ANY BREAKS IN THE LINE WILL ALSO NEED TO BE MONITORED FOR A
TORNADO THREAT AS WELL.
HELD OFF ON A FLASH FLOOD WATCH FOR NORTHERN AND NORTHEASTERN
COUNTIES WITH FORECASTED RAIN TOTALS GENERALLY IN THE 1 TO 3 INCH
RANGE OVER THE NEXT 24 HOURS... WHICH IS BELOW PRESENT 1 HOUR
FLASH FLOOD GUIDANCE VALUES. HOWEVER... LOCALLY HEAVY RAINFALL
WILL CERTAINLY BE POSSIBLE ACROSS SOUTHEAST TEXAS AS PRECIPITABLE
WATER VALUES CLIMB ABOVE 2 INCHES /NEARING RECORD MAXIMUM VALUES
FOR THIS TIME OF YEAR/. A SPECIAL 18Z SOUNDING OUT OF CORPUS
CHRISTI TODAY AND THE KHGX VAD WIND PROFILER THIS AFTERNOON SHOWED
A LARGELY UNIDIRECTIONAL FLOW IN PLACE ACROSS THE REGION... AND
THIS WILL ENCOURAGE TRAINING OF SHOWERS AND THUNDERSTORMS FOR THE
REMAINDER OF THE EVENING AND INTO THE OVERNIGHT HOURS. WILL NEED
TO MONITOR FOR A LOCALIZED FLOODING THREAT AND PLAN TO CONTINUE TO
HIGHLIGHT THIS IN THE HAZARDOUS WEATHER OUTLOOK.
A TIGHTENING SURFACE PRESSURE GRADIENT AHEAD OF THE APPROACHING
COLD FRONT WILL CAUSE WINDS TO INCREASE ACROSS THE AREA TONIGHT...
AND HAVE ISSUED A WIND ADVISORY IN RESPONSE TO THE INCREASING
GRADIENT WINDS OVER THE SOUTHERN COUNTIES. WINDS MAY NOT QUITE
REACH WIND ADVISORY CRITERIA AS FAR INLAND AS THE CURRENT ADVISORY
HIGHLIGHTS... BUT GIVEN THE NUMBER OF HOLIDAY ACTIVITIES PLANNED
FOR THIS WEEKEND CHOSE TO HIGHLIGHT THE POTENTIAL FOR ELEVATED
WINDS. EXPECT THE GRADIENT TO RELAX BEHIND THE SQUALL LINE/COLD
FRONT BY MIDDAY SUNDAY... WITH GENERALLY LIGHT WINDS AND CLEARING
SKIES EXPECTED IN THE WAKE OF THE FRONT SUNDAY AFTERNOON AND
EVENING.
HUFFMAN
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
MUCH DRIER CONDITIONS ARE EXPECTED FOR THE BEGINNING OF THE WORK
WEEK... WITH RETURN FLOW RESUMING BY TUESDAY. AN APPROACHING UPPER
DISTURBANCE FROM THE WEST WILL SEND ANOTHER COLD FRONT INTO THE
AREA TUESDAY NIGHT INTO WEDNESDAY... AND THIS COMBINED WITH
INCREASING MOISTURE WILL RESULT IN RETURNING RAIN CHANCES TOWARDS
THE MIDDLE OF THE WEEK. MUCH COOLER AND DRIER CONDITIONS ARE
EXPECTED IN THE WAKE OF THIS MID-WEEK COLD FRONT... WITH HIGH
TEMPERATURES TOWARDS THE END OF THE WEEK IN THE 50S AND 60S.
HUFFMAN
&&
.MARINE...
WINDS AND SEAS WILL CONTINUE TO BUILD UNDER A TIGHTENING PRESSURE
GRADIENT. FOR THE REMAINDER OF THE AFTERNOON...ON INTO THE EVENING
HOURS...AND OVERNIGHT...SOUTH WINDS AT 20 TO 30 KNOTS WITH HIGHER
GUTS ALONG WITH 6 TO 8 FOOT SEAS NEARSHORE AND 7 TO 10 FOOT SEAS
OFFSHORE WILL BE COMMON. CAUTION FLAGS FOR THE BAYS THIS AFTERNOON
WILL BECOME SMALL CRAFT ADVISORIES BEGINNING THIS EVENING. ALL
WATERS WILL THEN HAVE ADVISORIES THROUGH NOON ON SUNDAY. EXPECT
POSSIBLE SHOWERS AND THUNDERSTORMS AT ANY TIME AHEAD OF A SQUALL
LINE THAT SHOULD ENTER AND RACE THROUGH THE WATERS AFTER SUNRISE
TOMORROW MORNING. LOOK OUT FOR POSSIBLE VERY STRONG WIND GUSTS AND
ISOLATED WATERSPOUTS. NORTHWEST TO WEST WINDS AND ELEVATED SEAS
WILL BOTH COME DOWN SUNDAY NIGHT AND MONDAY AS THE STORM SYSTEM
MOVES OFF TO THE EAST. MODERATE SOUTH TO SOUTHEAST WINDS COME BACK
TO THE AREA ON MONDAY NIGHT AND TUESDAY. THE NEXT COLD FRONT MOVES
THROUGH THE WATERS LATE TUESDAY NIGHT THROUGH EARLY WEDNESDAY MORNING.
CAUTION FLAGS AND ADVISORIES WILL BE NEEDED BEHIND THIS FRONT FOR
BOTH STRENGTHENING NORTH WINDS AND BUILDING SEAS.
TIDES COULD CLIMB INTO THE 3.0 TO 3.5 FEET RANGE ALONG THE GULF
FACING SHORES THIS AFTERNOON AND THIS EVENING DURING HIGH TIDE TIMES.
EXTENSIVE BEACH WAVE RUN UP/STRONGER RIP CURRENTS AND NUISANCE BEACH
FLOODING ARE POSSIBLE DURING THIS TIME FRAME. 42
