The episode as NWS MOB wrote it up.
During the evening of 4 April 2011, a fast moving and intense cold front moved southeast into a very warm, moist and unstable air mass along the Alabama and northwest Florida Gulf Coasts. Immediately along and ahead of the cold front, a line of severe thunderstorms, already ongoing, moved out of southeast Mississippi during the early evening and progressed across southern Alabama and the western Florida Panhandle through midnight.
In total, there were numerous reports of tree and power line damage as the squall line moved through. There were no known deaths or injuries.
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 Apr 4, 5:41 PM CST, 3 hours 34 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MOBILE AL
641 PM CDT MON APR 4 2011
...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS EVENING OVER
THE NORTHERN HALF OF THE FCST AREA...ROUGHLY ALONG AND NORTH OF
HIGHWAY 84...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ELSEWHERE ACROSS
THE FCST AREA...
.AVIATION (00Z ISSUANCE)...USED 21Z RUC HRRR FOR TIMING THE
CONVECTIVE LINE APPROACHING FROM THE WEST BASED ON LATEST TRENDS.
WILL HAVE TEMPO GROUPS FROM 01-03Z AT MOB-BFM AND 03-05Z AT PNS WITH
WIND GUSTS TO 35-40 KNOTS AND LIFR CONDITIONS IN THUNDERSTORMS.
NORTHWEST WINDS AT 17-18 KNOTS FOLLOW BY 03Z MOB-BFM AND 05Z PNS
WITH MVFR CEILINGS NEAR 1.5 KFT...THEN VFR CONDITIONS FOLLOW BY 08Z
MOB-BFM AND 10Z PNS WITH GUSTY NORTHERLY WINDS CONTINUING THROUGH
THE REMAINDER OF THE TAF PERIOD. /29
&&
.SHORT TERM (THIS EVENING)...LATEST THINKING ON EVENT TIMING IS THAT
SQUALL LINE WILL MOVE INTO INTERIOR SE MS COUNTIES BETWEEN 6 PM AND
7 PM...PRIOR TO THIS TIME...SOME ISOLATED SHOWERS AND STORMS WILL BE
POSSIBLE OVER THIS AREA PRIOR TO THE ARRIVAL OF THE MAIN
LINE...HOWEVER. LINE TIMING WILL PROGRESS TO I-65 BY 10 PM AND THEN
FROM ROUGHLY GREENVILLE AL TO DESTIN BY MIDNIGHT. THIS IS SUPPORTED
BY FOUR CONSECUTIVE MOB WRF- NMM RUNS (INCLUDING THE NEW RUN WHICH
JUST CAME IN)...LATEST MOB WRF-ARW AND THE RUC HRRR. VSBL SAT
IMAGERY SHOWS HORIZONTAL ROLLS IN BOUNDARY LAYER ATTM...SO PARTIAL
INSOLATION AIDING MLCAPES WSW-ENE AXIS OF 2000 J/KG MLCAPES ALONG
AND JUST N OF I-10 CORRIDOR. ALSO...UPSTREAM 18Z LIX SOUNDING SHOWS
0-6 KM DEEP LAYER SHEAR SUPPORTIVE OF THAT QLCS WITH EMBEDDED LEWPS
AND BOWS.
ONE NOTABLE ITEM IS THE SFC-800 HPA EQUIV POTENTIAL TEMP LAPSE OF 32
K. DEEP LAYER OF DRY AIR FROM 850-300 HPA WILL ALLOW ALL UPDRAFTS
REACHING INTO THIS LAYER TO HAVE STRONG EVAPORATIONAL COOLING. WBZ
HEIGHTS ~9 KFT...WHICH WILL PORTEND LARGE DIAMETER HAIL THREAT.
LOCAL CONCERN...GIVEN OBSERVED PRE-STORM ENVIRONMENTAL PARAMETERS
AND SHORT-TERM FORECAST FROM LOCAL MODELS...CAN SEE DECENT DAMAGING
WIND AND LARGE HAIL THREAT IN THAT CORRIDOR ALONG AND NORTH OF I-10
WHERE AFOREMENTIONED MLCAPES ARE NOW APPROACHING 2500 J/KG. 60-80
MPH WIND GUSTS WITH BOWS ARE NOT OF THE QUESTION ALONG THIS AXIS.
TORNADOES ARE ALSO POSSIBLE...BUT LACK OF SELY SFC WINDS ARE TO SOME
DEGREE LIMITING 0-1 KM VWS VALUES SOMEWHAT...ALTHOUGH ISOLATED
TORNADOES REMAIN VERY MUCH POSSIBLE ESPECIALLY ALONG THE LEADING
EDGE OF BOWS AND ANY ISOLATED STORMS THAT FORM AHEAD OF THE LINE
DURING THE REMAINDER OF THE AFTERNOON AND EARLY EVENING.
ONE FINAL NOTE. BELIEVE WE WILL SEE CONVECTION INITIATE WELL AHEAD
OF THE SQUALL LINE BY 530 PM FROM COVINGTON COUNTY AND SOUTH INTO
OKALOOSA COUNTY. AM NOTING NICE AREA OF PERSISTENT 250-800 HPA
DIFFERENTIAL DIVERGENCE. THESE STORMS SHOULD REMAIN BELOW SEVERE
LIMITS AS THEY MOVE OFF QUICKLY TO THE EAST BEFORE SUNSET.
OTHERWISE...EXPECT WINDY CONDITIONS TO CONTINUE THIS EVENING IN
ADVANCE OF THE FRONT AS VWP'S CONTINUE TO SHOW ABOUT 40 KNOT SWLY
WINDS AT AROUND 3KFT. MANY LOCATIONS HAVE BEEN GUSTING TO 30 TO 35
KNOTS AT THE SFC THIS AFTERNOON...AND GUSTS WILL ONLY SLIGHTLY
DIMINISH AFTER SUNSET THIS EVENING. A WIND ADVISORY IS IN EFFECT
UNTIL 10 PM FOR ALL OF THE FCST AREA.
LOW TEMPERATURES TONIGHT WILL BE COOLER THAN LAST NIGHT IN THE WAKE
OF THE FRONT. OVER NORTHWESTERN ZONES SIGNIFICANTLY COOLER
MINS...WITH AREAS ALONG AND NORTH-WEST OF I-65 FALLING INTO THE
LOWER/MIDDLE 40S BY DAYBREAK WEDNESDAY. EAST OF I-65 AND CLOSER TO
THE COAST...OVERNIGHT MIN TEMPS ARE EXPECTED TO BE IN THE LOWER 50S.
23/JMM...12/DS
.(TUESDAY THROUGH WEDNESDAY NIGHT)...HIGH PRESSURE WILL BRING DRIER
AND COOLER AIR TO THE REGION IN THE WAKE OF THE FRONT ON TUESDAY.
MOST...IF NOT ALL OF THE PCPN IS EXPECTED TO BE EAST OF THE FCST AREA
BY SUNRISE TUESDAY...WITH DRY AND RAINFREE CONDITIONS THEN EXPECTED
FOR THE REMAINDER OF THE SHORT TERM PERIOD. OVERNIGHT LOW TEMPS WILL
BE BELOW NORMAL TUESDAY NIGHT...POSSIBLY APPROACHING THE FREEZING
MARK (AT LEAST INTO THE LOW/MID 30S) OVER NORTHEASTERN ZONES BY
SUNRISE WEDNESDAY. FROST WILL BE POSSIBLE EARLY WEDNESDAY
MORNING...AND TONIGHTS MIDNIGHT SHIFT WILL LIKELY ISSUE A FROST
ADVISORY FOR PARTS OF THE FCST AREA FOR WEDNESDAY MORNING. ON
WEDNESDAY HIGH TEMPS WILL BE IN THE LOW/MID 70S. 12/DS
.LONG TERM (THURSDAY THROUGH MONDAY)...NO CHANGES TO MEDIUM/LONGTERM
PACKAGE THIS AFTERNOON. A MODERATING TREND IN TEMPERATURES IS
EXPECTED DURING THE MEDIUM RANGE. HIGH PRES MOVES E AND BECOMES QUITE
EXPANSIVE OVR THE WRN ATLC WITH ITS WESTWARD NOSE EXTENDING BACK INTO
THE CENTRAL GULF. BROAD UPPER LVL HIGH OVR THE GULF WILL KEEP THE
BETTER DEFINED WX SYSTEMS RIDING N AND E FM THE PLAINS INTO THE UPPER
MIDWEST. COULD SEE A SMALL CHC OF SHWRS/TSTMS ON FRI AS TAIL END OF
WEAK MID LVL DISTURBANCES RIDE ENE IN THE HIGH LVL FLOW. LACK OF ANY
SFC BOUNDARY SHOULD KEEP CHC'S BLO 30% FRI AFTN.
UPPER RIDGE STRENGTHENING OVER THE GULF THIS WEEKEND IMPLIES DEEP LYR
SUBSIDENCE AND LITTLE CHC OF RAIN SAT/SUN. WILL ALSO BE FEELING LIKE
SUMMER W/HIGH TEMPERATURES IN THE MID/UPPER 80S BY SAT. NIGHTTIME
MINS WILL LIFTING TO WELL INTO THE 60S BY THE WEEKEND AS WELL. /10
&&
.MARINE...SOUTHERLY WINDS AND SEAS WILL STEADILY INCREASE AHEAD OF A
STRONG COLD FRONT APPROACHING FROM THE NORTHWEST. SEAS WILL BUILD TO
6 TO 8 FEET OUT TO 60 NM THIS EVENING...BUILDING TO 7 TO 9 FEET FROM
20 TO 60 NM OUT WITH THE WIND SHIFT OVERNIGHT. A SOLID LINE OF
STRONG TO SEVERE THUNDERSTORMS CAN BE EXPECTED AHEAD OF THE COLD
FRONT LATER THIS EVENING. A STRONG NORTHERLY WIND FLOW WILL DEVELOP
IN THE WAKE OF THE COLD FRONT LATE TONIGHT AND CONTINUE THROUGH
EARLY TUESDAY AFTERNOON THEN GRADUALLY DECREASE THROUGH TUESDAY
NIGHT. A LIGHT TO MODERATE SOUTHERLY FLOW WILL REDEVELOP BY
WEDNESDAY AFTERNOON AND CONTINUE THROUGH SATURDAY AS HIGH PRESSURE
BUILDS OVER THE EASTERN GULF.
A SMALL CRAFT ADVISORY REMAINS IN EFFECT FOR ALL MARINE ZONES
THROUGH 7 PM THIS EVENING...UPGRADED TO A GALE WARNING FROM 7 PM
THIS EVENING THROUGH 9 AM TUESDAY MORNING...FOLLOWED BY A SMALL
CRAFT ADVISORY THROUGH 2 PM TUESDAY AFTERNOON. 32/EE

.FIRE WEATHER...A COLD FRONT WILL MOVE ACROSS THE REGION LATE THIS
AFTERNOON AND THIS EVENING...BRINGING SHOWERS AND THUNDERSTORMS TO
THE AREA. RAINFALL TOTALS OF 1 TO 1.5 INCHES WILL BE LIKELY AT MOST
LOCATIONS...WITH ISOLATED HEAVIER AMOUNTS POSSIBLE. A MUCH DRIER
AIRMASS WILL WORK INTO THE REGION IN THE WAKE OF THE FRONT ON
TUESDAY...WITH DISPERSIONS IN THE 70S AND RELATIVE HUMIDITIES IN THE
MID TO UPPER 20S. A WEATHER WATCH IN EFFECT FROM TUESDAY AFTERNOON
THROUGH TUESDAY EVENING FOR THE WESTERN FLORIDA PANHANDLE DUE TO

THERE WILL BE A POTENTIAL OF SEVERE STORMS OVER SOUTHEAST MISSISSIPPI AND EXTREME PORTIONS OF SOUTHWEST ALABAMA BEGINNING AROUND 6 PM TO 7 PM THIS EVENING AS THE SQUALL LINE MOVES INTO THE OUTLOOK AREA. THE SQUALL LINE WILL THEN ADVANCE EAST ACROSS THE ENTIRE OUTLOOK AREA THROUGH 10 PM THIS EVENING...THEN EXIT THE OUTLOOK AREA BY AROUND MIDNIGHT. THIS SPEED OF MOTION IS SLIGHTLY FASTER THAN EARLIER INDICATED OVER THE EASTERN HALF OF THE AREA. DATA STILL SUGGESTS THAT SEVERE THUNDERSTORMS WILL BE LIKELY ALONG THIS LINE OF STORMS...WITH DAMAGING WINDS AND LARGE HAIL BEING THE PRIMARY THREATS. IN ADVANCE OF THE LINE...ISOLATED THUNDERSTORM CELLS MAY DEVELOP...AND SOME OF THESE STORMS WILL ALSO BE CAPABLE OF PRODUCING DAMAGING WINDS...LARGE HAIL...AND ISOLATED TORNADOES.
