The episode as NWS MOB wrote it up.
Thunderstorms developed across the western Florida panhandle and produced high winds which caused damage.
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 Jul 30, 10:26 AM CST, 1 hour 41 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MOBILE AL
1126 AM CDT MON JUL 30 2012
.MESOSCALE UPDATE...THE ATMOSPHERE HAS QUICKLY BECOME VERY UNSTABLE
WITH MLCAPES ALREADY AT 3500-4000 J/KG AS OF 15Z. MLCAPES WILL
LIKELY TOP OUT AT 4500 J/KG ALONG THE COASTAL ZONES THIS AFTERNOON.
AN UPPER LEVEL DISTURBANCE IS CURRENTLY PRODUCING SCATTERED SHOWERS
AND STORMS OVER W CTRL AL/E CTRL MS. THIS FEATURE WILL CONTINUE TO
TRACK SOUTH TODAY AND WILL LIKELY SERVE AS A TRIGGER FOR SCATTERED
THUNDERSTORM DEVELOPMENT AS IT INTERACTS WITH THE HIGHLY UNSTABLE
AIRMASS. COVERAGE MAY BE FURTHER ENHANCED ACROSS THE COASTAL ZONES
AS SFC WINDS TURN SW DUE TO THE DEVELOPING SEABREEZE CIRCULATION...
ENHANCING LOW LEVEL CONVERGENCE. UPDATED THE FORECAST TO INCREASE
POPS TO 40-50 PERCENT ACROSS THE FORECAST AREA.
THERE IS A SLIGHT RISK OF SEVERE STORMS ACROSS THE AREA TODAY GIVEN
THE OBSERVED INSTABILITY...HIGH MOISTURE (PWATS NEAR 2 INCHES)...AND
0-6 KM BULK SHEAR INCREASING TO 30-35 KT. THE MAIN SEVERE THREATS
WILL BE LOCALIZED DAMAGING WIND GUSTS AND HAIL UP TO QUARTER SIZE.
HEAT INDICES ARE FORECAST TO REACH 108 DEGREES ACROSS THE COASTAL
ZONES AS UPPER 70 DEWPOINTS PERSIST THIS AFTERNOON DUE TO THE
DEVELOPING SW WINDS. THEREFORE A HEAT ADVISORY HAS BEEN ISSUED FOR
THOSE ZONES. 16Z OBS SHOW A FEW INLAND LOCATIONS APPROACHING
ADVISORY CRITERIA...HOWEVER...DEWPOINTS ARE FORECAST TO MIX OUT A
LITTLE THIS AFTERNOON...WHICH WOULD BRING INDICES BACK TO SLIGHTLY
BELOW CRITERIA. WILL CONTINUE TO MONITOR OBS AND WILL MAKE
ADJUSTMENTS TO THE ADVISORY AS NECESSARY.
WILL LEAVE RAIN CHANCES AS IS FOR TONIGHT GIVEN THE CONTINUED
NORTHERLY UPPER LEVEL FLOW. THERE IS UNCERTAINTY ON IF WE WILL SEE A
COMPLEX (MCS) APPROACH US TONIGHT. AT THIS TIME THERE IS LITTLE
SUPPORT FROM THE HI-RES GUIDANCE. WE WILL CONTINUE TO EVALUATE THIS
POSSIBILITY. 34/JFB
&&
.PREVIOUS DISCUSSION (ISSUED 333 AM CDT MON JUL 30 2012)...
.SHORT TERM (TODAY AND TONIGHT)...MAIN CONCERN FOR THE NEXT 24 HOURS
WILL BE WARMER THAN NORMAL TEMPS ACROSS MUCH OF THE DEEP SOUTH
RESULTING IN HEAT INDICES RANGING FROM 103 TO 107 ACROSS MUCH OF THE
CWFA TODAY...DUE TO INCREASED SUBSIDENCE FROM DEEP RIDGE SETTING UP
THE WEST...FOLLOWED BY AN ACTIVE NORTHERLY FLOW IN THE MID TO UPPER
LEVELS OVERNIGHT...POSSIBLY LEADING TO A FEW STRONG THUNDERSTORMS IN
THE FORM OF A MCS MOVING SOUTHWARD ACROSS NORTHERN AND EASTERN
SECTIONS OF THE CWFA OVERNIGHT. THE GFS...ECMWF AND NAM ALL SHOW
THIS PATTERN OVERNIGHT WITH THE GFS ALSO HAVING CONVECTIVE FEEDBACK
ISSUES WELL TO THE NORTH AS THIS MID LEVEL ENERGY SURGES SOUTHWARD
ACROSS THE CENTRAL PART OF THE STATE. AT THE SURFACE A BROAD AREA OF
LOW PRESSURE DEVELOPS ON THE WESTERN SIDE OF THE UPPER RIDGE WHICH
IS LIKELY A REFLECTION OF THE STRONG IMPULSE/MCS PUSHING DOWN FROM
NORTH. TO THE SOUTH A WEAK FRONTAL BOUNDARY IS NOTED ACROSS THE
NORTHERN PART OF THE CWFA REMAINING QUASI-STATIONARY THROUGH TONIGHT
WITH A SOMEWHAT ACTIVE SEABREEZE CIRCULATION SETTING UP FURTHER
SOUTH RESULTING IN SCATTERED THUNDERSTORMS FORMING ALONG THE
SEABREEZE FRONT...DEVELOPING MOSTLY ACROSS INLAND AREAS NEAR THE
COAST BY MIDDAY SHIFTING INLAND THROUGH LATE THIS AFTERNOON. LATEST
MODEL SOUNDINGS DEPICT A IMPRESSIVE MOISTURE COLUMN SETTING UP LATER
TODAY AND OVERNIGHT WITH PWATS STARTING OUT AROUND 1.4 INCHES AT 12Z
TODAY CLIMBING TO 2.10 BY 12Z TUE MOSTLY OVER NORTHERN AND EASTERN
SECTIONS OF THE CWFA. WITH THIS WILL MAKE A FEW ADJUSTMENT TO THE
CURRENT FORECAST GENERALLY SHOWING SCATTERED COVERAGE OF SHOWERS AND
THUNDERSTORMS OVER COASTAL AND LOWER SECTIONS OF THE CWFA EARLY THIS
AFTERNOON FOLLOWED BY MORE COVERAGE OVERNIGHT...MOVING IN FROM THE
NORTH. FOR NOW WILL MENTION A FEW STRONG TO SEVERE STORMS WILL BE
POSSIBLE WITH THE NORTHERLY FLOW OVERNIGHT WITH A MORE GENERAL
THUNDERSTORM FORECAST EARLIER IN THE DAY CLOSER TO THE COAST. LATEST
THINKING FROM SPC PLACES MUCH OF THE CWFA UNDER A SLIGHT RISK WITH
THE CONVECTION MOVING SOUTHWARD OVERNIGHT. FOR TEMPS WILL LEAN
TOWARDS THE WARMER MAV GUIDANCE THROUGH TONIGHT DUE TO THE INCREASED
SUBSIDENCE FROM THE WEST. 32/EE
THE WET MICROBURST RISK FOR TODAY IS MODERATE.
FOR TUESDAY THROUGH WEDNESDAY NIGHT...THE AXIS OF A MID/UPPER TROF
REMAINS OVER THE EASTERNMOST STATES WITH MID/UPPER RIDGING OVER THE
SOUTHERN PLAINS EXTENDING EASTWARD INTO THE REGION. ABUNDANT DEEP
LAYER MOISTURE WILL BE IN PLACE WITH PRECIPITABLE WATER VALUES NEAR
2.2 INCHES...ABOUT 135 PERCENT OF NORMAL...THROUGH WEDNESDAY NIGHT.
A SURFACE RIDGE CONTINUES OVER THE NORTHERN GULF PROMOTING A
SOUTHWESTERLY LOW LEVEL FLOW WITH AFTERNOON SEA BREEZE DEVELOPMENT
EACH DAY. A CONCERN IS THAT MODEL GUIDANCE HAS BEEN HINTING AT MCS
DEVELOPMENT IN THE PERSISTENT DEEP LAYER NORTHWESTERLY FLOW WHICH
COULD BRING AFTERNOON TO NOCTURNAL CONVECTION INTO THE FORECAST AREA
BUT DIFFICULT AT THIS POINT TO DETERMINE TIMING AND PLACEMENT. FOR
NOW WILL HAVE LOW END CHANCE POPS OVER THE WESTERNMOST PORTION OF
THE AREA ON TUESDAY...WITH COVERAGE LIMITED BY THE LESS FAVORABLE
CONVECTIVE ENVIRONMENT FROM THE RIDGING ALOFT...INCREASING TO GOOD
CHANCE POPS OVER THE EASTERN PORTION WHERE COVERAGE WILL BE ENHANCED
BY A SHORTWAVE SYSTEM MOVING ACROSS THE SOUTHEAST STATES...AND MAY
ALSO SEE CONVECTION LEFT OVER FROM MCS MENTIONED FOR MONDAY NIGHT.
0-1 KM MLCAPES WILL REACH AROUND 2500 J/KG AND SPC HAS PLACED MUCH
OF THE FORECAST AREA IN A SLIGHT RISK EXCEPT FOR THE WESTERN THIRD
OF THE AREA...WHERE EFFECTS OF RIDGING IS EXPECTED TO LIMIT
CONVECTIVE DEVELOPMENT. ANY SEVERE STORMS THAT DEVELOP WILL BE OF
THE PULSE VARIETY WITH WIND GUSTS IN EXCESS OF 60 MPH. SIMILAR
CONDITIONS ARE PRESENT FOR WEDNESDAY EXCEPT THAT WHILE ANOTHER
SHORTWAVE IS EXPECTED TO MOVE ACROSS THE AREA...THIS IS A WEAKER
FEATURE THAN THE ONE MOVING ACROSS THE REGION ON TUESDAY. THE
EASTERN STATES TROF STRENGTHENS SLIGHTLY ON WEDNESDAY WHICH REDUCES
THE EFFECTS OF THE UPPER RIDGING ON THE AREA AND 0-1 KM MLCAPES ARE
EXPECTED TO REACH 2500-3000 J/KG. WILL CONTINUE WITH CHANCE POPS
FOR THE AREA FOR WEDNESDAY AND LIKE TUESDAY THERE WILL BE THE
POTENTIAL FOR STRONG TO POSSIBLY SEVERE STORM DEVELOPMENT. THE
STRONGER STORMS THROUGH THE PERIOD WILL BE CAPABLE OF PROLIFIC
LIGHTNING AND HEAVY DOWNPOURS AS WELL. AFTERNOON HEAT INDICES WILL
BE 102-107 BOTH DAYS THOUGH A FEW SPOTS MAY HIT AROUND 108 BUT NOT
SUFFICIENT COVERAGE FOR A HEAT ADVISORY...AT LEAST AT THIS TIME. /29
.LONG TERM (THURSDAY THROUGH SUNDAY)...THE LONGWAVE TROF WEAKENS
THROUGH THURSDAY NIGHT LEAVING THE FORECAST AREA MAINLY UNDER THE
INFLUENCE OF THE EASTERN EXTENSION OF THE SOUTHERN PLAINS UPPER
RIDGE. A SURFACE RIDGE PERSISTS OVER THE NORTHERN GULF AND
MAINTAINS A SOUTHERLY FLOW WITH SCATTERED CONVECTION EXPECTED WITH
THE SEA BREEZE DEVELOPMENT EACH DAY. DEEP LAYER MOISTURE REMAINS
ELEVATED EARLY ON IN THE PERIOD...WITH PRECIPITABLE WATER VALUES
NEAR 2.2 INCHES THOUGH DECREASES SOMEWHAT TO AROUND 2 INCHES INTO
THE WEEKEND DUE TO INCREASING SUBSIDENCE EFFECTS. AFTERNOON HEAT
INDICES WILL BE GENERALLY 100-106 EACH DAY. /29
.MARINE...SFC RIDGE MAINTAINS OVER MUCH OF THE NORTHERN GULF THROUGH
THE FORECAST PD. WEAK FRONTAL BOUNDARY STALLED OVER INTERIOR
SECTIONS OF AL AND MS COMBINED WITH STRONG SFC RIDGE OVER THE
NORTHERN GULF...ALONG WITH GOOD AFTERNOON HEATING INLAND...RESULTS
IN A MODERATE SW FLOW OVER THE MARINE AREA THIS AFTERNOON AND EARLY
TONIGHT. GENERALLY A WEST TO SOUTHWEST FLOW CONTINUES THROUGH THE
WEEK WITH HIGHER WINDS AND SEAS MOSTLY FROM THE SW DURING THE
AFTERNOON AND EARLY EVENING HOURS. SEAS MOSTLY AROUND 2 FEET THROUGH
FORECAST PD BUILDING TO 3 FEET AT TIMES EACH AFTERNOON MOSTLY OVER
THE NORTHERN HALF OF THE MARINE AREA DUE TO DAYTIME HEATING AND
BETTER SEABREEZE CIRCULATIONS. BAYS AND INLAND WATERWAYS WILL BE
MOSTLY A LIGHT TO MODERATE CHOP THROUGH THE FORECAST PD. IF STRONG
IMPULSE/MCS HOLDS TOGETHER OVERNIGHT THERE COULD BE A FEW STRONG
THUNDERSTORMS MOVING SOUTHWARD TOWARDS THE COAST AND OFFSHORE
OVERNIGHT TONIGHT. 32/EE
.AVIATION...[12Z ISSUANCE]...VFR TO MVFR CONDITIONS THROUGH 12Z TUE.
LOWER CEILINGS WILL BE MAINLY IN AND AROUND SCATTERED SHOWERS AND
THUNDERSTORMS OCCURRING MOSTLY DURING THE AFTERNOON AND EARLY
EVENING HOURS NEAR THE COAST FOLLOWED BY MORE CONVECTION MOVING DOWN
FROM THE NORTH OVERNIGHT. MOSTLY A WEST TO SOUTHWEST WIND FLOW AT 5
TO 10 KNOTS EARLY TODAY BECOMING MOSTLY SOUTHWEST AT 8 TO 12 KNOTS
WITH POSSIBLE HIGHER GUSTS BY MID TO LATE AFTERNOON THEN BECOMING
WEST AT 4 TO 6 KNOTS LATER THIS EVENING AND OVERNIGHT OR THROUGH 12Z
TUE. 32/EE
.FIRE WEATHER...WHILE AFTERNOON RELATIVE HUMIDITIES REMAIN ABOVE
CRITICAL LEVELS THROUGH THE WEEK...FREQUENT LIGHTNING AND BRIEF
STRONG WIND GUSTS OF VARYING DIRECTION WILL ACCOMPANY SCATTERED
STORMS THAT DEVELOP EACH DAY. DAILY DISPERSION VALUES WILL BE
GENERALLY GOOD THROUGH WEDNESDAY. PATCHY LIGHT FOG IS POSSIBLE
DURING THE EARLY MORNING HOURS...BUT IS NOT FORECAST TO BE A
WIDESPREAD CONCERN. /29
