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 Aug 5, 12:10 PM CST, 1 hour 5 minutes earlier.
AREA FORECAST DISCUSSION...AVIATION UPDATE NATIONAL WEATHER SERVICE MOBILE AL 110 PM CDT WED AUG 5 2009 ...AVIATION UPDATE...THUNDERSTORM ACTIVITY NOW DEVELOPING ACROSS THE LOCAL FLYING AREA WILL CONTINUE INTO THE EARLY EVENING. COVERAGE SHOULD REMAIN GREATEST OVER THE WESTERN FLORIDA PANHANDLE AND THE COASTAL COUNTIES OF ALABAMA. SOUNDINGS INDICATE STRONG MICROBURST POTENTIAL WITH THE STRONGER STORMS LIKELY CREATING LOCALIZED LLWS AND X-WIND CONCERNS. ASIDE FROM AREAS IN AND AROUND THUNDERSTORMS...VFR CONDITIONS WILL PREVAIL INTO THE EARLY EVENING WITH PATCHY AREAS OF MVFR FOG DEVELOPING NEAR WATER SOURCES AND ALONG THE COAST. /JW ***********************PREVIOUS FORECAST***************************** .MESOSCALE UPDATE...AN OUTFLOW BOUNDARY FROM A DECAYING MCS OVER THE MIDSOUTH CONTINUES TO MARCH SOUTH...NOW MOVING OVER THE NW CWA. THE NAM AND GFS HAVE NOT HAD A GOOD HANDLE ON THE EVOLUTION OF THE MCS...AND AS CAN BE EXPECTED HAS A HARD TIME HANDLING THE PROGRESS OF RESULTANT OUTFLOWS. THE BIGGEST PUSH TO THE OUTFLOW IS ACROSS MISSISSIPPI...WITH THE BOUNDARY LAGGING SOME ACROSS SOUTHWEST ALABAMA. AS THE OUTFLOW CONTINUES TO MOVE TOWARD THE COAST BY EARLY AFTERNOON...IT WILL INTERACT NOT ONLY WITH AN UNSTABLE AIRMASS WITH MLCAPES OF AROUND 2500 J/KG...BUT YET ANOTHER STRONG OUTFLOW BOUNDARY FROM A STRONG THUNDERSTORM COMPLEX THAT OCCURRED SOUTH OF DAUPHIN ISLAND THIS MORNING AND THE DEVELOPING AFTERNOON SEABREEZE. THIS SHOULD RESULT IN AN INCREASE OF THUNDERSTORM COVERAGE THIS AFTERNOON...ESPECIALLY ALONG AND EAST OF INTERSTATE 65. BASED ON THE PROGRESS OF THE AFOREMENTIONED BOUNDARIES...HAVE REORIENTED POPS TO BE HIGHEST (50S) IN THE SOUTH AND EAST ZONES...AND LOWEST (30S) IN THE NW ZONES WHERE THE BOUNDARY IS ALREADY PASSING. THE UPDATED WET MICROBURST CHECKLIST CAME IN WITH A HIGH RISK. THIS SUGGESTS THAT THE STRONGER STORMS WILL HAVE A LIKELY POTENTIAL TO PRODUCE 35-45 KT WIND GUSTS...WITH A SLIGHT RISK OF SEVERE GUSTS OF 50 KT OR GREATER. LARGE HAIL DOES NOT LOOK TO BE A SIGNIFICANT RISK WITH WETBULB ZEROES NEAR 13 KFT IN THE WEST. THESE VALUES ARE LOWER ACROSS THE FAR EASTERN CWA (AROUND 10.5 KFT)...SO A GREATER POTENTIAL FOR HAIL (PEA TO PERHAPS PENNY SIZE) EXISTS IN THOSE LOCATIONS. ALSO ADJUSTING MAX TEMPS TO LOWER THEM SLIGHTLY IN THE NW AND INCREASE THEM FURTHER EAST. THE NET RESULT IS STILL HIGHS IN THE LOW TO MID 90S. 34/JFB /PREVIOUS DISCUSSION ISSUED 401 AM CDT WED AUG 5 2009/ .SHORT TERM...(TODAY AND TONIGHT)...CURRENTLY WATCHING A DECAYING MCS ACROSS NORTHERN MISSISSIPPI AND ALABAMA EARLY THIS MORNING. THIS SYSTEM HAS PUT OUT AN OUTFLOW BOUNDARY THAT WILL MOVE SOUTHWARD INTO THE REGION TODAY. THIS BOUNDARY WILL ENCOUNTER A VERY UNSTABLE AIRMASS ACROSS THE CENTRAL GULF COAST WITH TEMPS IN THE LOW TO MID 90S AND DEWPOINTS IN THE LOW 70S...RESULTING IN SBCAPE VALUES OF 3-4K J/KG. THE MAV HAS BEEN TOO DRY WITH ITS POPS THE LAST FEW DAYS AND THAT WILL LIKELY BE THE CASE AGAIN TODAY ESPECIALLY WITH THE OUTFLOW BOUNDARY MOVING IN. DUE TO THE ABOVE FACTORS...HAVE LEANED TOWARD THE WETTER MET POP NUMBERS TODAY. FORECAST SOUNDINGS ACROSS THE AREA THIS AFTERNOON INDICATE A NEARLY CLASSIC WET MICROBURST PROFILE WITH WINDEX VALUES AROUND 65 KNOTS. PRELIMINARY ANALYSIS ALSO INDICATES A HIGH RISK OF MICROBURSTS WITH THUNDERSTORMS THIS AFTERNOON. IN ADDITION TO GUSTY WINDS...LARGE HAIL IS A POSSIBILITY DUE TO LARGE CAPE IN THE HAIL GROWTH REGION AND LOW WBZ LEVELS AS A RESULT OF THE MID LEVEL DRY AIR. SPC HAS INTERIOR PORTIONS OF THE AREA IN A SLIGHT RISK WITH 15% HAIL AND WIND THREATS. /13 TODAYS WET MICROBURST RISK: HIGH. THURSDAY THROUGH FRIDAY NIGHT...THURSDAY WILL CONTINUE TO BE DOMINATED BY INTERACTION OF OUTFLOW BOUNDARIES...THE SEA BREEZE AND THE TAIL END OF A MID LEVEL TROUGH. HIGHER POPS ON THURSDAY WILL BE OVER THE EASTERN HALF...CLOSER TO THE DEEPER MOISTURE AND UPPER TROUGH...BUT AS IN THE PAST SEVERAL DAYS...MOST ANYPLACE MAY CATCH A THUNDERSTORM ON THURSDAY. CHANGES BEGIN TO OCCUR THURSDAY NIGHT AS THE UPPER TROUGH DEPARTS AND THE UPPER HIGH OFF TO THE NORTHWEST EXPANDS EAST AS AN EASTERLY WAVE MOVES ACROSS THE NORTHEAST GULF. MAV MOS HAS POPS LESS THAN 20 PERCENT FOR FRIDAY ACROSS THE AREA SO WE WILL GO CLOSER TO THE NAM MOS WHICH HAS BEEN A BETTER FIT LATELY ANYWAY. WILL KEEP A SLIGHT CHANCE IN FOR FRIDAY NIGHT AS THE WAVE WEAKENS AS IT MOVES ON SHORE. AS USUAL TEMPERATURES WILL BE TIED TO THE CONVECTION INITIATION AND ATTENDANT CLOUD COVER BUT MOST PLACES SHOULD BE IN THE LOW TO MID 90S FOR HIGHS ON THURSDAY AND FRIDAY. /11 && .LONG TERM...(SATURDAY THROUGH TUESDAY)THE UPPER HIGH CONTINUES TO DRIFT EAST OVER THE WEEKEND...SETTING UP OVER THE MID ATLANTIC COAST BY SUNDAY THEN RIDGING BACK TO THE WEST THROUGH TUESDAY. THIS KEEPS THE FORECAST AREA IN A DEEP AND MOIST SOUTHEAST FLOW INTO MONDAY THEN MORE SOUTHERLY AS THE RIDGE DEVELOPS. FORECAST WILL HAVE A CHANCE FOR SHOWERS AND THUNDERSTORMS EACH DAY WITH HIGH TEMPERATURES AROUND 90...ABOUT NORMAL CONDITIONS FOR THIS TIME OF YEAR. /11 && .AVIATION (12Z ISSUANCE)...GENERALLY VFR CONDITIONS EXPECTED EARLY THIS MORNING WITH VCTS BY LATE MORNING. MVFR/IFR CONDITIONS EXPECTED IN AND AROUND SCATTERED SHOWERS AND THUNDERSTORMS DURING THE AFTERNOON HOURS. /13 && .MARINE...A GENERALLY LIGHT WEST TO SOUTHWEST FLOW WILL PREVAIL THROUGH MID WEEK AS WEAK HIGH PRESSURE REMAINS ACROSS THE NORTHERN GULF. A SOUTHEASTERLY FLOW RETURNS OVER THE WEEKEND AS HIGH PRESSURE OVER THE WESTERN ATLANTIC RIDGES WESTWARD. /13 && .PRELIMINARY POINT TEMPS/POPS...
