The episode as NWS TAE wrote it up.
A fairly widespread outbreak of severe thunderstorms occurred on Labor Day across much of the NWS Tallahassee County Warning Area (CWA). This event was forced by unseasonably strong wind fields associated with a potent extra-tropical cyclone that was formerly Tropical Storm Lee. Post-tropical cyclone Lee was moving slowly toward the east-northeast along the north central Gulf Coast during the morning hours of September 5, 2011. By 3:00 pm EDT (1900 UTC), the cyclone was centered near Mobile Bay. It was at this point that the system finally began to accelerate off to the northeast. While tornadoes were initially considered to be the primary threat, examination of a special 1800 UTC KTAE sounding showed that low level winds had veered and that the flow was unidirectional through a deep layer. WFO Tallahassee coordinated with the Storm Prediction Center (SPC) to replace the existing tornado watch with a severe thunderstorm watch at 4:00 pm EDT (2000 UTC). WFO Tallahassee issued a total of 35 convective warnings during the event along with several special marine warnings. A total of 52 severe weather reports were received across southeast Alabama, southwest and south central Georgia, and the Florida panhandle and big bend.
Aside from the severe weather, the forecast area experienced other peripheral impacts from post-tropical storm Lee. Widespread storm-total rainfall of 3 to 6 inches was measured across the Florida panhandle and big bend, with 1 to 2 inch totals more common across the Alabama and Georgia portions of the CWA.
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 Tallahassee, FL wrote its last area forecast discussion before the first event at Sep 5, 10:28 AM EST, 3 hours 36 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
1128 AM EDT MON SEP 5 2011
...IMPACTS FROM TROPICAL DEPRESSION LEE TO BE FELT INTO TUESDAY...
...MODERATE RISK OF SEVERE STORMS TODAY OVER SOUTHEAST ALABAMA AND
SOUTHWEST GEORGIA WITH A SLIGHT RISK ELSEWHERE...
...GALE WARNINGS IN EFFECT FOR THE COASTAL WATERS...
.DISCUSSION...THE DEEP AREA OF LOW PRESSURE THAT WAS TROPICAL STORM
LEE IS CENTERED OVER SOUTHEAST LOUISIANA THIS MORNING. THIS LOW IS
FORECAST TO MOVE OFF TO THE NORTHEAST ACROSS SOUTHERN MISSISSIPPI
AND CENTRAL ALABAMA TODAY AND THEN INTO NORTH GEORGIA TONIGHT. A
FRONT EXTENDS NEWD FROM THE LOW CENTER ACROSS NRN AL AND ON INTO THE
APPALACHIANS. A COASTAL FRONT IS ALSO ANALYZED EWD ALONG THE GULF
COAST INTO THE FL PANHANDLE. A MODIFIED 12Z KTAE SOUNDING REVEALS
CAPE IN THE 2000-3000 J/KG RANGE. THIS INSTABILITY IN ACCOMPANIED BY
UNSEASONABLY HIGH SHEAR VALUES...PARTICULARLY IN THE LOWEST LAYERS.
THE RESULT IS A VERY RARE ASSESSMENT OF A MODERATE RISK FOR
TORNADOES ACROSS NWRN PORTIONS OF THE FORECAST AREA TODAY. WHILE THE
BEST CHANCE FOR SEVERE STORMS WILL BE NW OF AN ABY-DHN
LINE...VIRTUALLY ALL OF THE FORECAST AREA WILL HAVE A SEVERE WEATHER
THREAT TODAY.
WE ALSO CONTINUE TO SEE A FLASH FLOOD THREAT. GAGE CORRECTED 24
RAINFALL TOTALS ARE RUNNING ABOUT 3 INCHES ACROSS MUCH OF THE
REGION. WE EXPECT ANOTHER 3-4 INCHES ACROSS THE CWA. THESE TOTALS IN
AN OF THEMSELVES WILL NOT GET US TO FLASH FLOOD GUIDANCE.
HOWEVER...TRAINING OF ECHOES IN FEEDER BANDS COULD CAUSE PROBLEMS.
THEREFORE THE WATCH WILL REMAIN IN PLACE.
A WIND ADVISORY REMAINS IN PLACE ACROSS OUR COASTAL ZONES. IT LOOKS
LIKE WE WILL MARGINALLY REACH BOTH OUR SUSTAINED AND GUST CRITERIA.
AS FAR AS COASTAL FLOODING IS CONCERNED...WE ONLY SAW ABOUT ONE FOOT
DEPARTURES THIS MORNING. WE EXPECT SIMILAR DEPARTURES IN THE
PANHANDLE DURING THE NEXT HIGH TIDE CYCLE OVERNIGHT. THE WATCH WILL
LIKELY BE REPLACED BY A STATEMENT FOR THESE AREA. NOW OVER IN THE FL
BIG BEND...THE ET STORM SURGE GUIDANCE SHOWS DEPARTURES UP TO 2.5 FT
DURING THE TUE MORNING HIGH TIDE CYCLE. THIS WILL PRODUCE MAX STORM
TIDES OF 5 TO 6.2 FT ABOVE MLLW...ENOUGH TO CAUSE SOME MINOR
FLOODING. IT IS ANTICIPATED THAT THE WATCH WILL BE REPLACED BY A
COASTAL FLOOD ADVISORY FROM OCHLOCKONEE BAY AROUND TO THE SUWANNEE
RIVER ENTRANCE. ALL OF THESE COASTAL FLOODING DECISION WILL BE
FINALIZED WHEN WE GER A LOOK AT THE 12Z MODEL RUNS.
HIGH SURF AND DANGEROUS RIP CURRENTS CONTINUE TODAY WITH VICTORY AT
SEA CONDITIONS. SOME BEACH EROSION HAS LIKELY OCCURRED OVER IN THE
PANHANDLE.
&&
.MARINE...TODAY THROUGH FRIDAY.
SEAS ARE RUNNING 9-11 FT AT THE OFFSHORE BUOYS THIS MORNING AND ARE
EXPECTED TO BUILD AS HIGH AS 15 FT S OF THE PANHANDLE TONIGHT. EVEN
THE APALACHEE BAY ZONE WILL SEE SEAS RISE TO 8-9FT IN THE SRN PART
OF THE ZONE. ALTHOUGH SUSTAINED GALE FORCE WINDS SHOULD ONLY OCCUR
VERY BRIEFLY IF AT ALL...FREQUENT GUSTS TO GALE FORCE ARE EXPECTED
TO DEVELOP AS THE STRONG GRADIENT SURROUNDING THE REMNANTS OF LEE
MOVE OVER THE WATERS. WE DECIDED TO EXTEND THE GALE WARNING EWD
BASED ON THE GUST FORECAST TO INCLUDE THE REMAINDER OF THE COASTAL
WATERS. GALE FORCE GUSTS WILL END FROM W TO E BETWEEN 06-15Z TUE.
SCA CONDITIONS WILL THEN PERSIST UNTIL ABOUT 00Z WED WHEN SEAS WILL
FINALLY SUBSIDE BELOW CRITERIA. THEREFORE...OPERATORS OF SMALL OR
EVEN MODERATE SIZED CRAFT SHOULD NOT PLAN ON VENTURING FROM PORT
UNTIL WINDS AND SEAS SUBSIDE. LOOKING DOWN THE ROAD...A PERIOD OF
OFFSHORE FLOW IS EXPECTED BEHIND THE FRONT FOR THE MIDDLE AND LATER
PART OF THE WEEK.
&&
.AVIATION...THROUGH 12Z TUESDAY.
SHOWERS AND THUNDERSTORMS WILL BE MOVING ACROSS AREA TERMINALS
TODAY...BEGINNING WITH THE FLORIDA AND ALABAMA TERMINALS THIS
MORNING AND PROGRESSING TO THE GEORGIA TERMINALS THIS AFTERNOON.
EXPECT PERIODS OF MVFR CIGS AND VSBY WITH THESE STORMS. STRONG
SOUTHERLY WINDS ARE ALSO EXPECTED AT ALL TERMINALS WITH GUSTS
APPROACHING 30 KNOTS. CONDITIONS ARE EXPECTED TO IMPROVE OVERNIGHT
WITH LIGHTER WINDS AND LOWER RAIN CHANCES.
&&
.FIRE WEATHER...DEEP TROPICAL MOISTURE WILL REMAIN IN PLACE ACROSS
THE REGION THROUGH TUESDAY WITH NO FIRE WEATHER CONCERNS EXPECTED.
&&
.HYDROLOGY...RIVERINE FLOODING CONTINUES TO LOOK UNLIKELY AS
ANTECEDENT CONDITIONS WERE SO DRY DUE TO THE LONG TERM DROUGHT IN
THE AREA. THE CHOCTAWHATCHEE RIVER AR CARYVILLE IS FORECAST TO SEE
SHARP RISES OF ABOUT 9 FT...BUT THIS STILL KEEPS THE RIVER BELOW
ACTION STAGE. FLASH FLOODING WILL REMAIN A POSSIBILITY WITH
WIDESPREAD 3-5 INCH RAINFALL TOTALS EXPECTED THROUGH TUESDAY. THE
BEST CHANCE FOR THIS TYPE OF FLOODING WILL OCCUR IN AREAS WHERE N-S
ORIENTED BANDS TRAIN OVER THE SAME AREA...AND IN URBAN AREAS WHERE
DRAINAGE IS TYPICALLY LESS EFFICIENT.
&&
.PREV DISCUSSION...600 AM EDT MON SEP 5 2011
AT UPPER LEVELS...
THE LARGE SCALE LONGWAVE PATTERN REMAINS HIGHLY AMPLIFIED WITH
RIDGING OVER THE WEST HALF AND SHARP TROUGHING OVER THE EAST HALF OF
U.S WITH MAIN AXIS FROM ONTARIO SWD INTO NRN GULF WITH 576DM CUTOFF
LOW OVER NE LA...AND A WESTERN ATLANTIC RIDGE. DURING THE NEXT 24
HRS...THE TROUGH WILL MOVE SLOWLY EWD ACROSS THE ERN U.S. MODELS
SUGGEST DEEP LAYER MOISTURE WILL BE SLOWLY LIFTING NWD WITH REMNANTS
OF LEE. HOWEVER...ON THE EAST OF THE LOW...A VERY MOIST AIRMASS WILL
BE IN PLACE INTO TUESDAY WITH MODEL FORECASTS SHOWING AN AXIS OF
MODERATE INSTABILITY WHICH SHOULD ALSO BE NEAR PRONOUNCED LOW-LEVEL
JET FAVORING STRONG TO SEVERE STORMS.
AT LOWER LEVELS...
MAIN FEATURES ARE LOW OVER ONTARIO WITH COLD FRONT SSW THRU TN
VALLEY TO TROPICAL DEPRESSION LEE THEN SWD INTO GULF AND WWD INTO TX.
THERE REMAINS SOME MODEL DIVERGENCE OF FUTURE TRACK OF LEE. NAM AND
CANADIAN ARE ON THE ERN SIDE OF THE ENVELOPE WITH UPPER TROUGH/
CLOSED LOW YIELDING A SURFACE REFLECTION ON THE ERN FRINGE OF THE
MODEL SPREAD. LATEST GFS CONTINUE WITH FASTER NEWD PROGRESSION.
THE KEY DIFFERENCE IS THAT THE NAM EXTENDS ITS OVERALL TROUGH ALOFT
FARTHER EWD THAN THE GFS THRU SHORT TERM.
BASED ON NHC TRACK...DURING THE NEXT FEW DAYS...THE REMNANTS OF. LEE
SHOULD TURN TO THE NE WITH THE REMNANT LOW OVER CENTRAL ALABAMA BY
TUES MORNING...NRN ALABAMA BY LATE AFTN OR EARLY EVE AND ACROSS TN
VALLEY ON TUES NIGHT. IT WILL BECOME INCREASINGLY EXTRA-TROPICAL
WITH TIME AS IT BEGINS TO BECOME ABSORBED INTO THE UPPER SHORT WAVE
AND MERGE WITH THE FRONTAL SYSTEM WHICH MOVES ACROSS GULF COAST ON
TUES MORNING. GOOD MODEL AGREEMENT THAT REMNANT LOW MAY DEEPEN AND
THAT SOUTHERLY LOW-LEVEL WIND FIELD MAY ACTUALLY STRENGTHEN AS IT
INTERACTS WITH THE LONGWAVE TROUGH...WITH THE LIKELIHOOD OF 50+ KT
WINDS WITHIN THE LOWEST 1-2 KM TRANSLATING EASTWARD ACROSS THE SRN
HALF OF AL AND THE FL PANHANDLE INTO GA TODAY. IT WILL REMAIN
ENHANCED TONIGHT INTO TUESDAY AS IT INTERACTS WITH A SHORTWAVE
TROUGH AND THE COLD FRONT. IN WAKE OF THE COLD FRONT...A DRIER AND
COOLER AIRMASS WILL MOVE ACROSS THE AREA THROUGH THE END OF THE WEEK.
ALTHOUGH LEE HAS WEAKENED INTO A DEPRESSION...THERE REMAINS A THREAT
OF SEVERE WEATHER LATER TODAY. THE GREATEST RISK SHOULD REMAIN INVOF
THE NERN QUADRANT WHERE MOST FAVORABLE LOW-LEVEL VEERING/SHEAR WILL
REMAIN...NAMELY OUR WESTERN COUNTIES TODAY. THE FRONT WILL SWEEP
ACROSS THE AREA FROM W TO E LATE MON NIGHT INTO TUE MORNING BRINGING
AN END TO THE HEAVIER RAIN SHOWERS. WILL TAPER POPS FROM NW TO SE
AFTER FRONTAL PASSAGE. AFTER THE REMNANTS OF LEE WOBBLE OFF TO THE
NW...MODELS IMPLY THAT H5/H2 ERN TROUGH SLOWS AS IT MOVES INTO
OH/VALLEY WHICH WOULD SLOW THE EWD PROGRESS OF THE FRONT WHICH MAY
LINGER NEAR SE BIG BEND ON TUES EVE. THIS WILL KEEP RAIN CHANCES
IN THE FORECAST ACROSS THE SE ZONES THRU EVE.
LOCAL IMPACTS OF LEE...
AN ADDITIONAL 2-4 INCHES OF RAIN CAN BE EXPECTED OVER THE FL
PANHANDLE AND SE AL WITH AMOUNTS TAPERING OFF THE E TO AS LOW AS 1
INCHES OVER S CENTRAL GA. CONSIDERING RAINFALL THAT HAS ALREADY
OCCURRED...OVERALL STORM TOTALS WILL EXCEED 10 INCHES ACROSS PARTS
OF THE PANHANDLE. FLASH FLOOD WATCHES CONTINUE THRU TUESDAY MORNING
FOR THE CWA AND WE WILL CLOSELY MONITOR THE SITUATION IN CASE LOCAL
FLOOD WARNINGS ARE NECESSARY.
ANOTHER IMPACT FROM THIS SYSTEM WILL THE BATTERING SURF. THE HIGH
SURF ADVISORY AND ASSOCIATED HIGH RISK FOR RIP CURRENTS REMAIN
THROUGH TUESDAY EVENING.
A COASTAL FLOOD WATCH FOR THE ENTIRE COASTLINE PERSISTS INTO TUES
MORNING WITH THE MAIN THREAT COMING DURING THE TUE MORNING HIGH TIDE
CYCLE.
VERY STRONG ONSHORE FLOW WILL GENERATE WINDS AROUND 25 MPH WITH
HIGHER GUSTS ACROSS COASTAL FLORIDA...20 TO 25 MPH OVER ADJOINING
COUNTIES. THEREFORE A WIND ADVISORY WAS ISSUED.
FINALLY...SHEAR PROFILES WILL AGAIN SUPPORT THE FORMATION OF
TORNADOES TODAY (SEE BELOW).
SHORT TERM...TODAY THROUGH WEDNESDAY.
TODAY...BASED ON LOCAL SEVERE WX CONFIDENCE TOOL...THERE IS A 20-25%
CHANCE OF SEVERE WX ACROSS FL PANHANDLE (5-10% CHANCE OF A TORNADO)
DECREASING TO 15-20% CHANCE ACROSS SE ALA AND DECREASING EWD TO NIL
CHANCES ACROSS ERN COUNTIES. THE TORNADO FOCUS WILL BE THIS AFTN
WITHIN AN ENHANCED SHEAR AND MOISTURE-RICH ENVIRONMENT AND WITH
STRONG LOW LEVEL WIND SHEAR WITH STORM RELATIVE HUMIDITIES
INCREASING IN THE WARM SECTOR. SATELLITE ALREADY HINTING OF
MID-LEVEL DRY SLOT DEVELOPING ON BACK SIDE OF LEE AND THIS COULD
SPREAD ENE BY AFTERNOON...OR ESPECIALLY BY EVENING INCREASING
CHANCES OF LOW-TOPPED SUPERCELLS CAPABLE OF TORNADOES. SPC HAS THE
ENTIRE AREA IN A SLIGHT RISK FOR SEVERE STORMS INCLUDING 10% TORNADO
THREAT FOR WRN COUNTIES AND 5% THREAT FOR ERN COUNTIES AND WILL
INSERT T+ WRN HALF OF CWA. CAT POPS EXCEPT FOR LIKELY SE BIG BEND.
HEAVY RAIN IN BANDS AND LOCALIZED FLOODING ON ALREADY SATURATED
GROUND A GOOD BET. HIGHS MID 80S COAST TO LOW 90S S/CNTRL GA.
TONIGHT...WITH COLD FRONT BEGINNING TO MOVE EWD...POTENTIAL FOR
SQUALL LINE TYPE FEATURE TO ADVANCE ACROSS THE AREA LATE TONIGHT
INTO EARLY TUESDAY. LOCAL CONFIDENCE TOOL SHOWS AROUND 20-25% CHANCE
OF SEVERE WX ACROSS ERN BIG BEND DECREASING WWD TO NIL ACROSS WRN
MOST PANHANDLE. 50-60% POPS. LOWS FROM UPPER 60S SE ALA TO UPPER 70S
SE BIG BEND.
TUESDAY...COLD FRONT WILL CROSS EWD ACROSS THE LOCAL AREA ON TUES
WITH SHARP NW-SE POP GRADIENT AND THEN LIKELY STALL NEAR SE BIG
BEND. BY EVE. SPC HAS A MARGINAL SEVERE THREAT (5%) FOR SEVERE WX
ACROSS SRN GA AND NRN FL. AS NOTED ABOVE...EXPECT AN INCREASE OF
WINDS SE OF LEE'S CENTER WITH BREEZY AND GUSTY CONDITIONS EXPECTED.
30-40% POPS WRN HALF...TO 60-70% ERN HALF DAYTIME. 20-40% W-E POP
GRADIENT AT NIGHT.
WEDNESDAY....0-40% NW-SE POP GRADIENT.
LONG TERM (WEDNESDAY NIGHT THROUGH NEXT MONDAY)...BEGINNING OF THE
EXTENDED PERIOD SHOULD START OFF DRY AS A DRIER AIRMASS MOVES INTO
THE REGION IN THE WAKE OF LEE. GUIDANCE IS IN GOOD AGREEMENT THAT A
CUT-OFF UPPER LOW WILL REMAIN IN PLACE OVER THE EASTERN U.S. INTO
NEXT WEEKEND. THE FLOW AROUND THIS FEATURE IS EXPECTED TO CONTINUE
FUNNELING A RELATIVELY DRY AIRMASS INTO THE REGION FROM THE CENTRAL
U.S. IN ADDITION...RELATIVELY LOW HEIGHTS SHOULD KEEP HIGH
TEMPERATURES IN THE MID TO UPPER 80S ACROSS THE REGION INTO NEXT
WEEKEND. BY NEXT WEEKEND...LAST FEW RUNS OF GFS ARE TRYING TO
DEVELOP LOW PRESSURE OVER THE SOUTHERN GULF. HOWEVER...THIS APPEARS
TO BE AN OUTLIER SOLUTION AND WILL LEAN HEAVILY TO THE DRIER ECMWF
AND CANADIAN SOLUTIONS.
