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.

What forecasters said that day

The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Mobile, AL wrote its last area forecast discussion before this tornado warning went out at Dec 19, 11:30 PM CST, 6 hours 15 minutes earlier.

Area forecast discussion, Dec 19, 11:30 PM CST, 6 hours 15 minutes before

AREA FORECAST DISCUSSION...UPDATE TO AVIATION
NATIONAL WEATHER SERVICE MOBILE AL
1130 PM CST WED DEC 19 2012

.AVIATION (06Z ISSUANCE)...AS A FRONT APPROACHES THE AREA...IFR
LEVEL CIGS WITH INCREASING COVERAGE OF RAINSHOWERS IS EXPECTED
BEFORE SUNRISE. AROUND 12Z...A FRONT IS EXPECTED TO BEGIN TO CROSS
THE AREA...BRINGING LOCAL LIFR CIGS/VISBYS. STRONG NORTHWESTERLY
WINDS WILL FOLLOW THE FROPA AND SKIES ACROSS THE AREA CLEARING
THROUGH THE AFTERNOON INTO THE EVENING.

/16

&&

.SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)...LOW PRESSURE CURRENTLY
OVER THE TEXAS PANHANDLE WILL QUICKLY MOVE EAST NORTHEAST THROUGH
TOMORROW AS A POTENT SHORTWAVE MOVES EAST OUT OF THE FOUR CORNERS.
THE ATTENDANT COLD FRONT WILL BE IN THE VICINITY OF THE MS RIVER BY
12Z TOMORROW...NEAR I-65 BY 18Z...AND WELL EAST OF THE FORECAST AREA
BY 00Z. THE EVENING HOURS LOOK DRY ACROSS THE AREA WITH SHOWERS
LIKELY NOT DEVELOPING OVER THE WESTERN HALF OF THE AREA UNTIL AFTER
MIDNIGHT WHEN ISENTROPIC LIFT STRENGTHENS IN RESPONSE TO THE
INTENSIFYING SOUTHWESTERLY LOW LEVEL JET. THIS ACTIVITY WILL BE
LOCATED WELL AHEAD OF THE COLD FRONT WITH LITTLE TO NO INSTABILITY
PRESENT. THE MAIN RISK FOR STRONGER STORMS OCCURS ALONG AND
IMMEDIATELY AHEAD OF THE COLD FRONT WHERE THE STRONGEST DEEP LAYER
FORCING WILL BE PRESENT. THIS LINE WILL BE IN OR JUST TO THE WEST OF
OUR SE MS COUNTIES BY DAYBREAK...WITH THE LINE RAPIDLY MOVING EAST
THROUGH THE MORNING HOURS. WHILE DEEP LAYER SHEAR AND LOW LEVEL
HELICITY REMAIN SUPPORTIVE OF SEVERE WEATHER...MLCAPES STAY BELOW 500
J/KG IN ALL GUIDANCE WITH WARM MID LEVEL TEMPERATURES PRODUCING
MEAGER LAPSE RATES. THIS MEANS THAT THE CHANCES FOR VIGOROUS UPDRAFTS
WILL BE LIMITED AND THE LINE OF CONVECTION THAT COMES THROUGH WILL BE
LOW TOPPED WITH LITTLE LIGHTNING. ANOTHER NEGATIVE FACTOR FOR SEVERE
WEATHER IS THE ZONE OF UPPER LEVEL DIVERGENCE WILL BE LOCATED WELL TO
THE NORTHEAST OF THE FORECAST AREA AND NOT IN PHASE WITH THE LOW
LEVEL CONVERGENCE NOTED FURTHER SOUTH. WHILE WE ARE NOT EXPECTING AN
OUTBREAK OF SEVERE WEATHER...AN ISOLATED SEVERE CELL CANNOT BE RULED
OUT WITH LOCALIZED DAMAGING WIND GUSTS BEING THE PRIMARY THREAT IN
ANY LEWPS OR BOWS THAT DEVELOP ALONG THE LINE. THE BULK OF THE SHOWER
AND ISOLATED TSTM ACTIVITY IS EXPECTED TO PUSH EAST OF THE FORECAST
AREA DURING THE EARLY AFTERNOON HOURS. THE QUICK MOVEMENT OF THE
SYSTEM WILL LIMIT RAINFALL TOTALS TO UNDER AN INCH IN MOST LOCATIONS
WITH AVERAGE TOTALS OF ONE QUARTER TO ONE HALF INCH CURRENTLY
FORECAST.

IT WILL BECOME QUITE WINDY IMMEDIATELY AHEAD AND BEHIND THE COLD
FRONT. WINDS OF 30-40 KT ARE PRESENT IN THE MIXED LAYER THROUGH THE
DAY WITH MIXING BECOMING MAXIMIZED IN THE COLD AIR ADVECTION THAT
DEVELOPS IN THE WAKE OF THE FRONTAL PASSAGE THURSDAY AFTERNOON.
FREQUENT GUSTS OF 30-35 MPH ARE LIKELY WITH A FEW GUSTS TO 40 MPH. A
WIND ADVISORY HAS BEEN ISSUED FROM 9AM TO 7PM TOMORROW.

DEPICTED A NON DIURNAL TEMP CURVE TONIGHT AND TOMORROW WITH LOWS
BEING REACHED THIS EVENING...WARMING UP OVERNIGHT...HIGHS SET IN THE
MORNING/MIDDAY...WITH FALLING TEMPS BEHIND THE FRONT. HIGHS/LOWS
STILL COME CLOSE TO MAV/MET GUIDANCE AND DID NOT DEVIATE MUCH.
THURSDAY NIGHT WILL BE MUCH COLDER WITH LOWS DROPPING INTO THE LOW TO
MID 30S. A CONTINUED BREEZE OVERNIGHT WILL PLACE WIND CHILLS IN THE
20S.

A RETURN TO WINTER LIKE TEMPS WILL OCCUR ON FRIDAY WITH HIGHS ONLY
CLIMBING INTO THE LOW TO MID 50S WITH MOST LOCATIONS DROPPING BELOW
FREEZING FRIDAY NIGHT. 34/JFB

&&

.LONG TERM (SATURDAY THROUGH WEDNESDAY)...WEAK RIDGING TO ZONAL FLOW
ALOFT AND A LARGE SURFACE HIGH PRESSURE ACROSS THE SOUTHEAST STATES
WILL DOMINATE THE WEATHER PICTURE WITH ANOTHER DRY PERIOD THROUGH
THE WEEKEND. THE SURFACE HIGH WILL MOVE EAST INTO THE WESTERN
ATLANTIC EARLY IN THE WORK WEEK...BRINGING A RETURN FLOW AND LOW
LEVEL MOISTURE BACK ACROSS THE REGION. THIS AHEAD OF ANOTHER COLD
FRONT APPROACHING THE REGION FROM THE NORTHWEST. THIS WILL SET UP
SEVERAL ROUNDS OF SHOWERS AND STORMS ON MONDAY THROUGH WEDNESDAY.
THERE ARE STILL SOME DIFFERENCES BETWEEN THE RELIABLE GLOBAL MODELS
IN THE TIMING OF THE EVENTUAL FRONTAL PASSAGE. TEMPERATURES WILL
RETURN TO NEAR NORMAL OR JUST ABOVE NORMAL BY THE WEEKEND. 22/34

&&

.MARINE...SOUTHERLY WINDS AND SEAS WILL BUILD TONIGHT THROUGH
THURSDAY MORNING IN RESPONSE TO A STRONG COLD FRONT APPROACHING FROM
THE WEST. THE COLD FRONT WILL MOVE ACROSS THE MARINE AREA DURING THE
DAY THURSDAY WITH A STRONG OFFSHORE FLOW DEVELOPING IN THE WAKE OF
THE FRONT BY THE AFTERNOON AND CONTINUING THROUGH FRIDAY. NORTHERLY
WINDS WILL GRADUALLY DIMINISH FRIDAY AND SATURDAY AS HIGH PRESSURE
BUILDS IN FROM THE WEST. /13

&&

.FIRE WEATHER...A STRONG COLD FRONT WILL MOVE THROUGH THE REGION ON
THURSDAY. SHOWERS AND THUNDERSTORMS WILL ACCOMPANY THE FRONT AND MOST
LOCATIONS SHOULD EXPERIENCE A WETTING RAIN. IT WILL BECOME BREEZY TO
WINDY JUST AHEAD OF AND BEHIND THE FRONT. MUCH DRIER AND COOLER AIR
WILL FILTER INTO THE REGION THROUGH FRIDAY IN THE WAKE THE FRONT.
RELATIVE HUMIDITY VALUES WILL FALL TO CRITICAL LEVELS ACROSS THE
WESTERN FLORIDA PANHANDLE. IN ADDITION...ERC AND 20 FOOT WIND SPEEDS
ALSO NEAR CRITICAL LEVELS. THEREFORE...A FIRE WEATHER WATCH HAS BEEN
ISSUED FOR THAT AREA. HUMIDITY MAY ALSO COME CLOSE TO CRITICAL LEVELS
ACROSS SOUTHWEST AND SOUTH CENTRAL ALABAMA...AND A FIRE WEATHER WATCH
MAY BECOME NECESSARY. 34/JFB
