The episode as NWS MOB wrote it up.
Thunderstorms producing high winds caused damage across portions of the western Florida panhandle.
The local office's own words before the first event, 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 the first event at Feb 1, 3:22 PM CST, 2 hours 43 minutes earlier.
AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE MOBILE AL
322 PM CST TUE FEB 1 2011
.DISCUSSION...(TONIGHT INTO THE WEEKEND)TAKING A LOOK AT THE CURRENT
SITUATION OVER THE CONUS AND SURROUNDING AREAS...THE CURRENT UPPER
AIR ANALYSIS SHOWERS A STRONG SHORTWAVE SWINGING NORTHEAST AROUND THE
SE SIDE OF AN UPPER LOW OVER YELLOWSTONE. THIS STRONG SHORTWAVE IS
PUSHING A LINE SHRA/TSRA QUICKLY(45+ MPH) EASTWARD OVER EASTERN
MISS/SE LA/ AND W-RN AL AS I TYPE. THE SURFACE LOW ASSOCIATED WITH
THIS SHORTWAVE WAS LOCATED OVER S-ERN MO...WITH A STRONG COLD FRONT
STRETCHING SOUTH OVER THE MISS RIVER TO THE NW-ERN GULF OF MEX.
WITH THE BACK EDGE OF THE PRECIP ALONG AND EAST OF I-55 ON RADAR...AM
QUICKENING THE PACE OF THE PRECIP EXITING THE AREA FROM
GUIDANCE...WITH THE LAST EXITING EAST OF THE FA SHORTLY AFTER
MIDNIGHT. FROM THERE INTO WEDNESDAY...COLDER AIR MOVES IN. HAVE WENT
WITH A MODEL PHYSICAL BLEND OF THE GFS AND NAM FOR T/TD AS A
START...WITH THE MOS TYPICALLY HAVING PROBLEMS HANDLING FRONTAL
PASSAGES...MUCH LESS A STRONG ONE LIKE THIS. THIS RESULTS IN TEMPS
AT OF SIGNIFICANTLY BELOW MOS. FOR TONIGHT AND WEDNESDAY.
WEDNESDAY NIGHT IS WHERE THE FORECAST GETS REAL INTERESTING. AS THE
MAIN CLOSED LOW OVER YELLOWSTONE MEANDERS SOUTHWARD TO OVER NW
MEX...SEVERAL SHORTWAVES GET SENT NORTHEAST OVER THE GULF. THIS
WILL HELP TO INITIATE ISENTROPIC UPGLIDE SHOWERS OVER THE COLD
AIRMASS BEHIND THE FRONT OVER THE AREA. THE SHORTWAVES PASSING OVER
THE NORTHERN GULF WILL HELP TO PUSH THE COLDER AIR NORTHWARD...BUT
THE QUESTION FOR THE FORECAST IS HOW FAST. LOOKING AT MODELS
SOUNDINGS...SREF WINTER WX PROBS...AND MODEL THICKNESS DERIVED WX
TYPES...A SMALL CHANCE EXISTS THAT FZRA/IP WILL MIX IN INITIALLY
TOWARDS SUNRISE THURSDAY MORNING INTO THURSDAY MORNING. AM TAKING A
IT'S GOING TO BE ON THE WARM SIDE...BARELY...BUT IT WON'T TAKE MUCH
TO GET A WINTER MIX TO MIX IN. A GOOD THING IS THAT WITH THIS BEING
ON THE INITIAL PART OF THE PRECIP...IF IT DOES HAPPEN...AMOUNTS OF
IP/FZRA WILL BE LIGHT...AND AS THE THE UPPER SYSTEM APPROACHES THE
AREA THURSDAY INTO FRIDAY...THE SOUTHERLY PUSH OF AIR OVERFLOWING THE
COLD AIRMASS WILL SLOWLY WARM TEMPS UP ENOUGH TO CUT THE CHANCE OF
WINTER PRECIP OFF DURING THE DAY THURSDAY....AND AS THE SYSTEM PUSHES
EAST OF THE AREA IN THE WEEKEND...TEMPS ARE WARM ENOUGH THAT ANY
TRAILING PRECIP IS BEING ADVERTISED AS BEING LIQUID.
SEVERAL SHORTWAVES MOVE OVER THE AREA SUNDAY INTO NEXT WEEK FOR MOS
TO ADVERTISE A SLIGHT CHANCE FOR RAIN...THOUGH AM NOT EXPECTING
ANYTHING UNTIL MONDAY NIGHT INTO TUESDAY...WHEN A STRONG UPPER SYSTEM
APPROACHES THE AREA...THEN ENDS AS IT PUSHES A FRONT OVER THE AREA
EARLY TUESDAY...WITH COLD ADVECTION PRECIP BEHIND THE FRONT TUESDAY
AFTERNOON INTO TUESDAY NIGHT. GFS IS ADVERTISING THIS ENDING AS
SNOW...BUT THIS FAR OUT...A LOT CAN CHANGE.

.AVIATION...(18Z ISSUANCE)LOW CEILINGS NEAR 300 FT BEGINNING TO
DEVELOP SOME BREAKS...SUCH AS AT BFM. WILL CONTINUE WITH PREVAILING
LOW CEILINGS AT MOB-PNS WITH MVFR CEILING AT BFM...WITH TEMPO GROUP
FOR LIGHT THUNDERSTORMS WITH CEILINGS 500-700 FT THROUGH 21/22Z.
BASED ON WRF/RUC HRRR TIMING...WILL HAVE TEMPO GROUP FROM 21-24Z AT
MOB-BFM AND 22-02Z AT PNS FOR SQUALL LINE WITH NEAR LIFR CONDITIONS
AND VARIABLE WINDS 25 KNOTS GUSTING TO 40 KNOTS. IN THE WAKE OF THE
SQUALL LINE IFR CEILINGS CONTINUE WITH GUSTY WINDS BACKED SOMEWHAT
TO THE SSW...THEN CEILINGS LIFT TO MVFR BY 02-04Z WITH WINDS BACKING
TO THE NORTHWEST. WILL HAVE VFR CONDITIONS BY EARLY WEDNESDAY
MORNING. /29
&&
.MARINE...DEEPENING SURFACE LOW NEAR THE MISSISSIPPI/OHIO CONFLUENCE
MOVES OFF ALONG THE OHIO RIVER VALLEY AND BRINGS A STRONG COLD FRONT
THROUGH THE FORECAST AREA. SOUTHEAST WINDS CURRENTLY IN THE PROCESS
OF INCREASING ABOVE SMALL CRAFT ADVISORY CRITERIA AND WILL INCREASE
TO AROUND 25 KNOTS/25-30 KNOTS NEAR THE BEGINNING OF THE FIRST
PERIOD. NORTHWEST WINDS AROUND 25 KNOTS IN THE WAKE OF THE FRONT
BECOME NORTH AND SUBSIDE TO AROUND 20 KNOTS WELL OFFSHORE AT 15-20
KNOTS NEAR SHORE WEDNESDAY MORNING. THE OFFSHORE FLOW INCREASES
SOMEWHAT WITH NOCTURNAL COOLING...REACHING ADVISORY CRITERIA AGAIN
OVER THE NEAR SHORE WATERS. THE FLOW SUBSIDES AGAIN TO 15-20 KNOTS
THURSDAY AND REMAINS AROUND 20 KNOTS WELL OFFSHORE. THESE
CONDITIONS PERSIST THROUGH FRIDAY NIGHT AS THE RATHER STRONG SURFACE
HIGH WEAKENS WHILE BUILDING INTO THE PLAINS BUT THE GRADIENT IS
SUPPORTED BY A SURFACE LOW WHICH MOVES FROM THE SOUTH CENTRAL GULF
THURSDAY NIGHT NORTHEASTWARD TO THE CAROLINA COAST FRIDAY NIGHT. AS
THIS FEATURE EXITS...THE GRADIENT FINALLY RELAXES WITH THE SURFACE
HIGH SETTLING OVER THE NORTH CENTRAL GULF SATURDAY INTO SATURDAY
NIGHT. GUIDANCE OVER THE PAST FEW DAYS HAS BEEN CONSISTENT IN
MAINTAINING AROUND 20 KNOTS OVER THE OFFSHORE WATERS THROUGH THIS
PERIOD AND HAVE EXTENDED THE SMALL CRAFT ADVISORY THROUGH EARLY
SATURDAY MORNING FOR THIS PORTION. HAVE ALSO EXTENDED THE SMALL
CRAFT ADVISORY FOR THE NEAR SHORE WATERS AND MOBILE BAY THROUGH MID
THURSDAY MORNING DUE TO THE OFFSHORE FLOW INCREASING AGAIN TO NEAR
20 KNOTS WEDNESDAY NIGHT. /29
&&
.FIRE WEATHER...AFTER A STRONG COLD FRONT MOVES THROUGH THE AREA
TONIGHT...COLDER...DRIER AIR WILL MOVE IN. A SERIES OF SYSTEM MOVING
OVER THE NORTHERN GULF BEGINNING LATE WEDNESDAY NIGHT...WITH BEGIN TO
CAUSE RAIN TO SPREAD NORTH OVER THIS COLDER AIR. RAIN IS EXPECTED AT
THIS TIME ...THOUGH THERE EXIST A SMALL POSSIBILITY OF A MIXED BAG AS
THE NORTHERN END OF THE PRECIP SHIELD SPREADS NORTH LATE WEDNESDAY
NIGHT INTO THURSDAY. IT'S NOT UNTIL SATURDAY...SATURDAY NIGHT WHEN
THE MAIN UPPER SYSTEM MOVES EAST OF THE AREA THAT THE RAIN WILL END.
NO PROBLEMS NOTED WITH LOW RELATIVE HUMIDITY VALUES INTO THE WEEKEND.

29/16HAZARDOUS WEATHER OUTLOOK...UPDATED... NATIONAL WEATHER SERVICE MOBILE AL 212 PM CST TUE FEB 1 2011 ALZ051>064-FLZ001>006-GMZ630-650-655-670-675-MSZ067-075-076-078- 079-022000- CHOCTAW-WASHINGTON-CLARKE-WILCOX-MONROE-CONECUH-BUTLER-CRENSHAW- ESCAMBIA-COVINGTON-UPPER MOBILE-UPPER BALDWIN-LOWER MOBILE- LOWER BALDWIN-INLAND ESCAMBIA-COASTAL ESCAMBIA-INLAND SANTA ROSA- COASTAL SANTA ROSA-INLAND OKALOOSA-COASTAL OKALOOSA-MOBILE BAY- COASTAL WATERS FROM PENSACOLA FL TO PASCAGOULA MS OUT 20 NM- COASTAL WATERS FROM DESTIN TO PENSACOLA FL OUT 20 NM- WATERS FROM PENSACOLA FL TO PASCAGOULA MS FROM 20 TO 60 NM- WATERS FROM DESTIN TO PENSACOLA FL FROM 20 TO 60 NM-WAYNE-PERRY- GREENE-STONE-GEORGE- 212 PM CST TUE FEB 1 2011 THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF INTERIOR SOUTHEAST MISSISSIPPI...SOUTHWEST AND SOUTH CENTRAL ALABAMA...THE WESTERN FLORIDA PANHANDLE...AND THE ADJACENT GULF COASTAL WATERS OF ALABAMA AND NORTHWEST FLORIDA. .DAY ONE...THIS EVENING THROUGH WEDNESDAY AFTERNOON... A STRONG COLD FRONT CURRENTLY MOVING QUICKLY EASTWARD ACROSS EASTERN LOUISIANA AT MID AFTERNOON WILL CONTINUE ITS EASTWARD MOVEMENT ACROSS THE NORTH CENTRAL GULF COAST REGION THROUGH THE EVENING HOURS. IT IS FORECAST TO MOVE EAST OF THE WESTERN FLORIDA PANHANDLE AND SOUTH CENTRAL ALABAMA AROUND MIDNIGHT. WHILE THERE ARE SEVERAL SHORT THUNDERSTORM LINES ALONG AND JUST WEST OF I-65...THE MAIN THUNDERSTORM LINE ASSOCIATED WITH REPORTS OF DAMAGING WINDS AND LARGE HAIL IS LOCATED JUST WEST OF I-59...OR JUST ALONG AND AHEAD OF THE COLD FRONT. THIS LINE WAS OBSERVED TO BE MOVING EAST TOWARD OUR REGION AROUND 35 MPH. SO THERE IS NOW HIGHER CONFIDENCE ON THE TIMING OF THE SEVERE WEATHER THREAT...ALTHOUGH WE MUST EMPHASIZE THAT DEVELOPING THUNDERSTORMS AHEAD OF THE LINE HAVE A SLIM CHANCE OF PRODUCING ONE OR TWO BRIEF TORNADOES BEFORE THE MAIN LINE ARRIVES LATER THIS AFTERNOON AND EVENING. SO...THROUGH 6 PM CST...THE MAIN THUNDERSTORM LINE THAT REPRESENTS THE GREATEST SEVERE WEATHER THREAT WILL HAVE PROGRESSED EASTWARD THROUGH SOUTHEASTERN MISSISSIPPI AND TO JUST WEST OF THE I-65 CORRIDOR. BETWEEN 6 AND 8 PM...IT WILL MOVER OVER INTERIOR SOUTHWESTERN ALABAMA SOUTH TO AROUND GULF SHORES AND THEN FURTHER EAST INTO SOUTH CENTRAL ALABAMA AND EAST OF PENSACOLA FLORIDA DURING THE 8 TO 10 PM TIME FRAME. GIVEN THE FORECAST ORIENTATION OF THE THUNDERSTORM LINE...IT WILL BE SLOWER TO CLEAR THE WESTERN FLORIDA PANHANDLE. POINTS TO THE NORTH OF THE FLORIDA PANHANDLE WILL THEN EXPERIENCE THE PASSAGE OF THE LINE SOONER...AS MENTIONED ABOVE. RELATIVELY LOWER ATMOSPHERIC INSTABILITY COMBINED WITH COOLER NEAR SHORE WATERS WILL TEMPER THE SEVERITY OF ANY THUNDERSTORMS THAT DEVELOP...ESPECIALLY ALONG THE IMMEDIATE COAST. HOWEVER THUNDERSTORMS THAT DEVELOP INLAND MAY BECOME A BIT MORE INTENSE...ESPECIALLY BEFORE DARK. THE STRENGTH OF THE WIND ENERGY ALOFT ALONE...COMBINED WITH STRONG VERTICAL WIND SHEAR WILL BRING A RISK OF ISOLATED DAMAGING SEVERE THUNDERSTORM WIND GUSTS OR A SHORT LIVED TORNADO. THE SPEED OF THE SURFACE COLD FRONT WILL LIMIT THE RISK OF SIGNIFICANT FLOODING TODAY. EVENT TOTAL RAINFALL WILL AVERAGE ONE HALF TO ONE INCH. LOCALIZED TOTALS APPROACHING 2 TO 3 INCHES COULD HAPPEN IN ISOLATED LOCATIONS WHICH COULD BRING MINOR FLOODING TO SOME LOW LYING RURAL AREAS AND CAUSE URBAN DRAINAGE PROBLEMS. FOR THE MARINE AREA...SOUTHEASTERLY TO SOUTHERLY WINDS WILL CONTINUE TO INCREASE TODAY AHEAD OF THE APPROACHING COLD FRONT. SMALL CRAFT ADVISORIES ARE IN EFFECT AS SOUTHERLY WINDS STRENGTHEN TO 20 TO 30 KNOTS AND SEAS BUILDING TO 6 TO 8 FEET. STRONG NORTHERLY WINDS ...25 TO 30 KNOTS WITH HIGHER GUSTS...BEHIND THE COLD FRONT WILL FOLLOW IN THE WAKE OF THE FRONT LATE TONIGHT AND WILL ENDURE THROUGH MIDDAY WEDNESDAY. SEAS WILL BUILD FURTHER IN THE NORTHERLY FLOW TO 7 TO 9 FEET LATER TONIGHT. .DAYS TWO THROUGH SEVEN...WEDNESDAY AFTERNOON THROUGH MONDAY. A MODERATE TO STRONG OFFSHORE FLOW WILL PERSIST THROUGH THE END OF THE WEEK AS ANOTHER AREA OF LOW PRESSURE DEVELOPS OVER THE CENTRAL GULF. HAZARDOUS CONDITIONS FOR SMALL CRAFT WILL CONTINUE THROUGH MUCH OF THE WEEK. THE COLD FRONT WILL STALL ACROSS THE CENTRAL GULF OF MEXICO BY MID WEEK WITH MUCH COLDER AND DRIER AIR MOVING IN BEHIND IT. BY THURSDAY ANOTHER UPPER LEVEL DISTURBANCE WILL APPROACH FROM THE WEST WITH PRECIPITATION DEVELOPING ACROSS THE REGION THURSDAY INTO FRIDAY. AT THE MOMENT...TEMPERATURES APPEAR TO BE JUST ABOVE FREEZING...ENOUGH TO RESULT IN A COLD RAIN. A FURTHER DROP IN TEMPERATURE COULD BRING A WINTRY MIX OVER INLAND SOUTHEAST MISSISSIPPI AND SOUTH ALABAMA. THIS SITUATION WILL BE CAREFULLY MONITORED...WITH MORE DETAILS BEING PROVIDED AS THIS SYSTEM DRAWS CLOSER. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BECOME NECESSARY THIS AFTERNOON AND THIS EVENING FOR SEVERE WEATHER OPERATIONS. STAY TUNED FOR FURTHER UPDATES FROM THE NATIONAL WEATHER SERVICE.
