NWS Mobile, AL wrote its last area forecast discussion before the first event at Aug 10, 4:18 AM CST, 6 hours 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOBILE AL 518 AM CDT FRI AUG 10 2012 .SHORT TERM (TODAY AND TONIGHT)...SCATTERED SHOWERS HAVE DEVELOPED EARLY THIS MORNING ALONG AND EAST OF THE I-65 CORRIDOR AS A SHORTWAVE TROUGH MOVES THROUGH THE EASTERN CWA. THIS FEATURE WILL CONTINUE TO GRADUALLY SHIFT EAST THIS MORNING. MEANWHILE...A COUPLE OF ADDITIONAL UPPER LEVEL DISTURBANCES WILL MOVE IN ON THE HEELS OF THE DEPARTING SHORTWAVE. ONE SUCH FEATURE HAS PRODUCED SEVERAL ROUNDS OF CONVECTION OVER THE ARKLAMISS LATE LAST EVENING THROUGH EARLY THIS MORNING. THIS FEATURE WILL GRADUALLY MOVE SOUTHEAST TOWARD US THIS MORNING. MEANWHILE...ANOTHER SHORTWAVE OVER NE OK/NW AR WILL MOVE INTO THE NORTHERN CWA BY MID TO LATE AFTN. THESE FEATURES COMBINED WITH PRECIPITABLE WATERS STILL NEAR 2 INCHES ARE EXPECTED TO RESULT IN ROUNDS OF SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS THROUGH THE DAY. THE AMOUNT OF INSTABILITY WE WILL SEE TODAY IS STILL SOMEWHAT UNCERTAIN GIVEN THAT A STRONG OUTFLOW BOUNDARY YESTERDAY EVENING DROPPED DEWPOINTS INTO THE UPPER 60S OVER MUCH OF THE CWA. HOWEVER...SW WINDS ARE FORECAST TO STRENGTHEN TODAY...WHICH WILL USHER BACK IN DEWPOINTS IN THE LOW TO MID 70S...WHICH ARE OBSERVED BACK TO OUR SW OVER SE LOUISIANA. IR SATELLITE ALSO SHOWS MID AND HIGH CLOUDS THINNING OUT IN THE WAKE OF THE FIRST SHORTWAVE...WHICH SHOULD ALLOW US TO WARM QUICKLY THIS MORNING (ESPECIALLY OVER THE WESTERN ZONES). THEREFORE...MLCAPES OF 1500-2500 J/KG APPEAR ATTAINABLE...WHICH WOULD RESULT IN SOME STRONG STORMS PRODUCING GUSTY WINDS...FREQUENT TO NEAR CONTINUOUS LIGHTNING...AND TORRENTIAL DOWNPOURS. THE STORMS WILL BE VERY EFFICIENT RAIN PRODUCERS...WHICH WILL RESULT IN POSSIBLE LOCALIZED FLOODING ISSUES...ESPECIALLY IN URBAN AND LOW LYING AREAS. WENT A FEW DEGREES BELOW MAV GUIDANCE AGAIN TODAY GIVEN THE EXPECTED INCREASE IN CLOUDS/RAIN CHANCES. TODAY'S WET MICROBURST RISK IS MODERATE. RAIN CHANCES CONTINUE INTO TONIGHT AS A COLD FRONT MOVES INTO THE NW FORECAST AREA BY EARLY SATURDAY MORNING. THE BEST CHANCE FOR STORMS WILL SHIFT TO SOUTH AND EAST OF I-65 AFTER MIDNIGHT. THEREFORE... WILL MAINTAIN HIGH END CHANCE POPS (40-50%) THIS EVENING FOR ALL LOCATIONS...WITH POPS DECREASING OVER THE FAR NORTHERN ZONES AFTER MIDNIGHT. LOWS AGAIN IN THE LOW TO MID 70S. 34/JFB .SHORT TERM (SATURDAY THROUGH SUNDAY NIGHT)...COLD FRONT SHOULD BE NEAR I65 EARLY ON SATURDAY MORNING STALLING BRIEFLY BEFORE MOVING OFFSHORE LATER ON SATURDAY. IT APPEARS THIS WILL BE MAINLY A DROP IN SURFACE DEWPOINT ALTHOUGH DRY BULBS WILL DROP SOME AS WELL. THICKNESS WON'T FALL TOO FAR BELOW 5730 METERS OR SO. 500 MB TROUGH IS SHOWING A SLIGHT TILT WESTWARD WITH HEIGHT INDICATING A SMALL AMOUNT OF "COLD" ADVECTION IS STILL THERE. IT WOULD SEEM RATHER ANOMALOUS TO BE DISCUSSING BAROCLINITY IN AUGUST...BUT THERE IT IS. DEEP RIDGE TO THE WEST POINTS TO A DEEP NORTHWEST FLOW ALOFT AT LEAST FOR A COUPLE OF DAYS UNTIL THE WESTERLIES GO SLIGHTLY MORE ZONAL AND THICKNESS RETURNS TO GREATER THAN 5800 METERS. NOT MUCH OF A CHANGE IN LAYER TEMPERATURE...BUT EVEN THIS SMALL AMOUNT IS SOMEWHAT UNUSUAL FOR SUMMERTIME ALONG THE GULF COAST. VORTLOBES ARE SHOWN BY THE GFS TO BE RELATIVELY WEAK AND FEW IN NUMBER FOR THE NEXT 72 HOURS. AS FOR THE CONVECTIVE PICTURE...PRECIPITABLE WATER IS ABOUT 2.0 TO 2.25 INCHES...LAYER HUMIDITY IS ABOUT 60 TO 80 PERCENT...LI IS -4 AND CAPE IS ABOUT 2000 TO 2200. BEHIND THE FRONT PASSING THROUGH LATE SATURDAY...THESE PARAMETERS DROP SHARPLY EXCEPT FOR LI WHICH INCREASES TO +4 INDICATING RAPID INCREASE OF STABILITY. VERTICAL PROFILE SHOWS RH DROPPING WITH A FRONTAL INVERSION FORMING BETWEEN 800 AND 750 MB. Q VECTOR DIVERGENCE IS PRETTY DRAMATIC TOO CONSIDERING IT IS REACHING -8 AT 30N TO 35N IN THE MIDDLE OF SUMMER. HOWEVER THE CROSS SECTION INDICATES WEAKENING OMEGAS AHEAD OF A DEEP DRY PUSH. MODEL COMPARISON INDICATES SURPRISINGLY CLOSE PHASING FROM TAU 0 TO TAU 72...AND CLOSE TO MAV GUIDANCE FOR LOW CHANCE POP CATEGORY AS WELL AS TEMPERATURE WHICH AGAIN WILL BE NOT FAR BELOW NORMAL WITH THE FRONTAL PASSAGE. 77/BD .LONG TERM (MONDAY THROUGH THURSDAY)...RELATIVELY FEW CHART FEATURES TO SPEAK OF SAVE THE WEST EDGE OF AN ANTICYCLONE PUSHING IN FROM OUT OF WESTLANT. NO SURFACE FRONTS ALTHOUGH LONG WAVE TROUGH IS WELL ANCHORED ALONG 95W FROM MANITOBA TO SOUTHEAST TEXAS. WAVENUMBER 5 ANALYSIS KEEPS IT THERE FOR THE NEXT 7 DAYS. MODEL COMPARISON INDICATES CLOSE PHASING FROM TAU 72 TO TAU 120...THEN ALL THE WAY OUT TO TAU 168 BETWEEN ONLY THE EURO AND GFS. WE STAYED CLOSE TO MAV GUIDANCE FOR LOW CHANCE POP CATEGORY. TEMPERATURES REBOUNDING TO NORMAL. && .AVIATION (12Z ISSUANCE)...ANOTHER ROUND OF SCATTERED TO NUMEROUS STORMS EXPECTED AGAIN TODAY...CONTINUING INTO TONIGHT ESPECIALLY FOR COASTAL LOCATIONS. MVFR/IFR CIGS EXPECTED IN AND AROUND TSTM ACTIVITY ALONG WITH GUSTY AND ERRATIC WINDS. GENERAL WIND FLOW BEGINS LIGHT OF THE SW THIS MORNING...BUT WILL INCREASE TO NEAR 15 KT AT TIMES LATE MORNING THROUGH THE AFTERNOON. 34/JFB && .MARINE...A RIDGE OF HIGH PRESSURE ACROSS THE WESTERN ATLANTIC AND NORTHERN GULF WILL PERSIST THROUGH EARLY NEXT WEEK. MEANWHILE... A WEAK COLD FRONT WILL APPROACH FROM THE NORTHWEST...STALLING NEAR THE COAST OR JUST OFFSHORE BY SATURDAY NIGHT. SOUTHWEST FLOW ACROSS THE MARINE AREA WILL INCREASE SLIGHTLY (LIGHT TO MODERATE FLOW) THROUGH AHEAD OF THE APPROACHING FRONT. A LIGHT S-SW FLOW WILL CONTINUE THIS WEEKEND WEEKEND AS THE FRONT STALLS. SEAS WILL GENERALLY BE 3-5 FEET THROUGH EARLY SATURDAY...SUBSIDING TO 1-2 FEET BY THE SECOND HALF OF THE WEEKEND. SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED OVER THE COASTAL WATERS AHEAD OF THE FRONT...WITH RAIN CHANCES DECREASING BY SUNDAY. 34/JFB && .FIRE WEATHER...AN UPPER LEVEL TROUGH MOVING ACROSS THE REGION WILL KEEP RAIN CHANCES AND RELATIVE HUMIDITY HIGH THROUGH TODAY. LIGHT SOUTHWEST WINDS WILL PREVAIL THROUGH TODAY DUE TO A SURFACE RIDGE EXTENDING ACROSS THE NORTHERN GULF OF MEXICO. AFTERNOON DISPERSION GENERALLY IN THE 40S AND 50S BOTH TODAY AND SATURDAY WITH DAYTIME MIXING HEIGHT GENERALLY AROUND 6000 FEET DURING THE DAY...PLUS OR MINUS 300 FEET OR SO.
