NWS Mobile, AL wrote its last area forecast discussion before the first event at Aug 7, 3:35 AM CST, 9 hours 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOBILE AL 435 AM CDT TUE AUG 7 2012 .SHORT TERM [TODAY THROUGH WEDNESDAY NIGHT]...MID LEVEL CIRCULATION STILL VERY APPARENT ON RADAR IMAGERY THIS MORNING ACROSS SE AL...WHICH HAS SPARKED A RATHER SOLID BAND OF CONVECTION FROM SE AL INTO THE FL PANHANDLE...RIGHT ALONG AND EAST OF OUR FORECAST AREA BORDER. A SHORTWAVE NOW MOVING SOUTHEAST ACROSS NORTH AL/MS WILL BEGIN TO KICK THE AFOREMENTIONED FEATURE EAST TODAY...RESULTING IN THE BEST COVERAGE OF PRECIP BEING JUST EAST OF OUR FORECAST AREA. THIS IS SUPPORTED BY MOST OF THE GUIDANCE...ESPECIALLY THE NSSL WRF AND LATEST HRRR RUNS. DRIER AIR IN THE 700-500 MB LAYER IS FORECAST TO FILTER INTO MUCH OF THE AREA TODAY AS THE SHORTWAVE OVER NORTH AL/MS CONTINUES SOUTHEAST. THIS WILL LOWER PRECIPITABLE WATER VALUES TO AROUND 1.75 INCHES ACROSS FAR INLAND SE MS/SW AL...WITH 1.8-2.0 INCHES STILL PRESENT FURTHER SOUTH AND EAST. THIS IS STILL SUPPORTIVE OF DIURNAL CONVECTION...BUT THE DRIER MID LEVEL AIR MAY INHIBIT A GREATER AREAL COVERAGE (AS UPDRAFTS ENCOUNTER THIS INCREASINGLY DRY ATMOSPHERE). MEANWHILE...THE SHORTWAVE TO THE NORTH MAY SERVE AS AN ADDITIONAL TRIGGER FOR CONVECTION...BUT EASTERN MOST AREAS WILL EXPERIENCE SOME SUBSIDENCE ON THE WESTERN SIDE OF THE MID LEVEL LOW OVER SE AL. GIVEN THE CONFLICTING SIGNALS REGARDING PRECIP POTENTIAL...WILL GENERALLY GO WITH A 30-50 POP...EXPECTING THE GREATEST COVERAGE OF STORMS CORRELATING TO THE BETTER DEEP LAYER MOISTURE IN SOUTHERN AND EASTERN ZONES. HIGHS LOW TO MID 90S WEST OF I-65...NEAR 90 TO LOWER 90S FURTHER EAST. WILL MAINTAIN CHANCE POPS THROUGH THE EVENING HOURS...ESPECIALLY OVER SOUTHERN ZONES IN RESPONSE TO THE WEAK SHORTWAVE MOVING INTO THE SOUTHERN CWA BY 06Z. CONVECTIVE COVERAGES SHOULD DECREASE LATE EVENING/OVERNIGHT...LEAVING US WITH ANOTHER TYPICAL EARLY AUGUST NIGHT IN THE MUGGY LOW TO MID 70S...WITH UPPER 70S AT THE BEACHES. 34/JFB THIS AFTERNOON'S WET MICROBURST RISK IS MODERATE WEDNESDAY AND WEDNESDAY NIGHT...SUMMERTIME CONVECTIVE MODE EXPECTED THESE PERIODS WITH CHANCES OF SHOWERS/STORMS THROUGH THE DAY...WITH NIGHTTIME ACTIVITY DECREASING OVER LAND AND SCATTERED COVERAGES OVER THE COASTAL WATERS. /10 .LONG TERM [THURSDAY THROUGH MONDAY]...TO BEGIN THE LATTER HALF OF THE WEEK...THE 07.00Z GFS/ECMWF ARE CONSISTENT IN SHOWING THE CENTRAL GULF COAST AT THE BASE OF A LONG WAVE TROF. MID LEVEL IMPULSES SLIDING EASTWARD COMBINED WITH DEEP GULF MOISTURE AND AFTERNOON INSTABILITY SUPPORTS A MID/HIGH CHANCE PROBABILITY OF SEEING STORMS THROUGH THE COURSE OF THE DAY THURSDAY. NORTHWARD MOVING COASTAL SEABREEZE AND MESOSCALE STORM OUTFLOW BOUNDARIES WILL ALSO AID IN ADDITIONAL STORM INITIATION. WILL FOLLOW THE EXTENDED RANGE MOS GUIDANCE OF RAINFALL PROBABILITIES INTO THURSDAY NIGHT. THE BETTER FOCUS FOR STORM COVERAGE EXPECTED TO SET UP OVER THE COASTAL WATERS THURSDAY NIGHT AS SHEAR ZONE...DEEPEST GULF MOISTURE AND HIGHER INSTABILITY SIGNAL BECOMES ALIGNED THERE. FOR FRIDAY...LITTLE OVERALL CHANGE PERSISTS IN THE UPPER AIR PATTERN EXPECTED...WITH DIURNAL CHANCE OF DAILY STORMS. MOVING INTO THE WEEKEND...THE LATEST GLOBAL MODELS IN AGREEMENT WITH MANUAL MEDIUM RANGE PROGS BRINGS A PATTERN CHANGE...SHOWING A SURFACE FRONTAL BOUNDARY SLIPPING SOUTHWARD ALL THE WAY TO THE COAST SATURDAY THEN STALLING. A FEW RESULTS TO OCCUR. FIRST A SOUTHWARD DISPLACEMENT TO RAIN CHANCES. A GRADIENT OF HIGHER CHANCES...SOUTH OF THE FRONT...LOOK TO BE POSITIONED OVER THE COASTAL WATERS WITH PROGRESSIVELY LOWER CHANCES NORTHWARD...ACROSS AND NORTH OF THE FRONTAL ZONE. SECONDLY...MAY SEE LOW TEMPERATURES DOWN INTO THE MID/UPPER 60S OVER THE NORTHERN COUNTIES BY SUNDAY MORNING. AND THIRDLY...A BIT MORE DRY AIR FILTERING IN...RESULTS IN LOWER WEEKEND HEAT INDEX VALUES. BY MONDAY...THE FRONTAL BOUNDARY BEGINS TO LIFT BACK TO THE NORTH WITH A GRADUAL RETURN TO DIURNAL CHANCES OF STORMS. HIGH TEMPERATURES FORECAST TO RANGE FROM THE LOWER/MID 90S. /10 && .TROPICS...TROPICAL STORM ERNESTO FORECAST TO STRENGTHEN TO HURRICANE STATUS AS IT NEARS THE EAST CENTRAL YUCATAN PENINSULA TODAY. THE LATEST GWW/WNA WAVE MODEL DATA INDICATES A NORTHWARD PROPAGATION OF LONG PERIOD SWELL THROUGH THE YUCATAN CHANNEL AND SOUTHERN GULF THIS AFTERNOON AND TONIGHT. THE ARRIVAL OF 8 TO 11 SECOND SWELL PERIODS ON WEDNESDAY MAY BRING AN INCREASED RISK OF RIP CURRENTS ALONG THE BEACHES. /10 .AVIATION [12Z ISSUANCE]...EARLY MORNING MVFR/IFR STRATUS AND FOG WILL GIVE WAY TO PREDOMINATE VFR CONDITIONS BY MID MORNING. CHANCE FOR CONVECTION WILL INCREASE PRIMARILY AFTER 15Z...WITH SCATTERED STORMS EXPECTED BY THE AFTERNOON HOURS. SCATTERED STORMS MAY AFFECT COASTAL TERMINALS THROUGH MID TO LATE EVENING. PATCHY MVFR/IFR STRATUS AND FOG LIKELY TO RETURN BY EARLY WED MORN. 34/JFB && .MARINE...A GENERAL SOUTHWEST FLOW IS EXPECTED THROUGH THE END OF THE WEEK AS HIGH PRESSURE OVER THE CENTRAL AND WESTERN ATLANTIC RIDGES INTO THE GULF OF MEXICO. WINDS WILL GENERALLY BE LIGHT...BUT WILL BE ENHANCED SLIGHTLY NEAR SHORE DURING THE AFTERNOON HOURS DUE TO THE SEABREEZE. WINDS WILL INCREASE SLIGHTLY ACROSS THE ENTIRE MARINE AREA BY THE END OF THE WEEK AS A FRONT APPROACHES FROM THE NORTHWEST. THE FRONT IS FORECAST TO ALONG OR JUST NORTH OF THE COASTLINE BY SATURDAY...RESULTING IN LIGHTER AND VARIABLE WINDS OVER THE COASTAL WATERS. WINDS AND WAVES WILL BE HIGHER NEAR SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE FORECAST PERIOD. SEAS WILL START OUT 1-2 FEET THROUGH TONIGHT...BUT LONG PERIOD SWELL FROM T.S. ERNESTO IS FORECAST TO IMPACT THE COASTAL WATERS MID TO LATE WEEK WHICH WILL INCREASE SEAS TO 3-5 FT LATE WED THROUGH THURSDAY WITH WAVE PERIODS 10-12 SECONDS. THE STORM ITSELF IS FORECAST TO STAY WELL SOUTH OF THE AREA...MOVING INTO THE BAY OF CAMPECHE BY THURSDAY. 34/JFB && .FIRE WEATHER...DAILY DISPERSION LOOKS FAIR TO GOOD THE NEXT COUPLE DAYS. SCATTERED STORMS WILL BRING FREQUENT LIGHTNING ACTIVITY AND VARYING...BRIEF STRONG WIND GUST HAZARDS TO AGENCIES CONDUCTING DAILY CONTROL BURN OPERATIONS. LIGHT PATCHY FOG IS POSSIBLE DURING THE EARLY MORNING HOURS...MORE PROBABLE IN THOSE AREAS THAT SEE HEAVIER RAINS TODAY. /10 && .PRELIMINARY POINT TEMPS/POPS...

A FEW OF THE STORMS ARE EXPECTED TO BECOME STRONG WITH FREQUENT...POTENTIALLY DEADLY LIGHTNING...BRIEF STRONG WIND GUSTS FROM 35 TO 45 MPH AND LOCALLY HEAVY RAINS RESULTING IN LOCALIZED FLOODING IN POOR DRAINING AREAS. ALTHOUGH THE RISK OF SEVERE WEATHER IS LOW...A BRIEF SEVERE STORM CAN OCCUR ON AN ISOLATED BASIS. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY A MOIST AND UNSTABLE AIRMASS WILL KEEP THE RISK OF A HIGHER PROBABILITY OF THUNDERSTORMS EACH DAY THROUGH THE END OF THE WEEK...WITH SOMEWHAT LOWER PROBABILITIES AT NIGHT. DAILY STORMS CAN BE STRONG AT TIMES...WITH FREQUENT...POTENTIALLY DEADLY LIGHTNING...BRIEF STRONG WINDS AND LOCALLY HEAVY RAINS RESULTING IN LOCALIZED FLOODING IN POOR DRAINING AREAS. AS TROPICAL STORM ERNESTO MOVES WESTWARD OVER THE WEST CENTRAL CARIBBEAN INTO THE BAY OF CAMPECHE...HIGHER SWELL WILL MOVE NORTHWARD...ARRIVING OVER THE CENTRAL GULF COAST WEDNESDAY THROUGH FRIDAY.
