NWS Mobile, AL wrote its last area forecast discussion before the first event at May 7, 8:35 PM CST, 25 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MOBILE AL 935 PM CDT THU MAY 7 2009 .UPDATE...SATELLITE ANALYSIS AND RADAR TRENDS HAVE NOTED VERY LITTLE MOVEMENT TO A SMALL MULTI-CELL CLUSTER OF CONVECTION OVER SOUTHWEST ALABAMA...PRIMARILY AFFECTING PARTS OF CHOCTAW COUNTY BUT ALSO PARTS OF CLARKE AND WILCOX COUNTIES AS WELL. LOCALLY SATURATED ENVIRONMENT FROM SLOW MOVING CONVECTION COMBINED WITH PRECIPITABLE WATER VALUES OF AROUND 1.60-1.70 SUGGEST RAINFALL RATES OF OVER 2.0/HR IN THE MOST INTENSE CONVECTIVE CORES...AND IN FACT RADAR ESTIMATES CONFIRM THIS AND ALSO INDICATE LOCALIZED HOURLY RATES OF 3 TO 4 INCHES. WE EARLIER ISSUED AN URBAN AND SMALL STREAM ADVSY FOR MUCH OF THIS AREA THAT EXPIRED AT 915 PM...AND A FLASH FLOOD WARNING IS NOW IN EFFECT FOR SOUTHERN CHOCTAW COUNTY UNTIL 1045 PM. OTHERWISE...CONVECTION HAS DIMINISHED ACROSS THE REMAINDER OF THE FCST AREA AND WILL GRADUALLY BEGIN TO DIMINISH ACROSS THE AREAS NOTED ABOVE AS THE EVENING WEARS ON. HAVE ADJUSTED GRIDS AND UPDATED THE ZONE FCST PRODUCT FOR THE OVERNIGHT HOURS TO REFLECT TRENDS MENTIONED ABOVE. WILL HAVE TO MONITOR THE MULTI-CELL CLUSTER OVER THE NWRN PART OF THE FCST AREA...ESPECIALLY OVER CHOCTAW COUNTY...FOR FURTHER POSSIBLE FLASH FLOOD WARNINGS AND FCST ADJUSTMENTS. 12/DS ...PREVIOUS FCST DISCUSSION FROM 400 PM CDT THU MAY 7 2009 FOLLOWS... .SHORT TERM...LATEST SAT PICS AND RADAR LOOPS CONTINUE TO SHOW A FEW SCATTERED SHOWERS AND THUNDERSTORMS OVER THE NORTHERN HALF OF THE CWFA MOSTLY FROM CONTINUED MOISTURE CONVERGENCE IN THE LOWER LEVELS COMBINED WITH WEAK MID LEVEL FORCING ALOFT FROM WEAK IMPULSE TRACKING EASTWARD OVER THE LOWER MS RIVER VALLEY AND COLD POOL IN THE LOWER LEVELS WITH PASSING MCS TO THE NE OF THE CWFA. LATEST WRF AND NAM12 SUGGEST INCREASE DRYING IN THE MID TO UPPER LAYERS LATER THIS AFT AND THIS EVENING RESULTING IN MOST OF THE CONVECTION TO THE NORTH ENDING QUICKLY AFTER SUNSET. WITH CONTINUED FLOW FROM THE SOUTH AND INCREASED SUBSIDENCE ALOFT MOVING IN FROM THE WEST FROM BETTER RIDGING ALOFT CONDITIONS WILL CONTINUE TO FEEL MUGGY THROUGH TONIGHT AND EARLY FRIDAY. WILL STAY CLOSE TO THE EARLIER FORECAST MINS FOR TONIGHT THOUGH GO A TAD COOLER THAN THE EARLIER PACKAGE GENERALLY OVER INLAND AREAS OF THE SE PART OF THE CWFA. /32 && .LONG TERM...MODELS CONTINUE TO SHOW MID TO UPPER ZONAL FLOW TO SHIFT NORTHWARD OVER THE WEEKEND WITH BETTER MID TO UPPER LEVEL SUBSIDENCE SHIFTING EASTWARD ACROSS THE DEEP SOUTH AND CENTRAL GULF COAST REGION...GENERALLY THROUGH SUN MIDDAY. AS A RESULT SFC RIDGE ACROSS THE WESTERN ATLANTIC AND EASTERN GULF WILL BUILD WEST ACROSS MUCH OF THE NORTHERN AND CENTRAL GULF THROUGH SUN GIVING WAY TO WARM TEMPS BOTH DAY AND NIGHT THROUGH EARLY NEXT WEEK. DEEP SOUTHERLY FLOW WILL SUBSIDE WITH THIS PATTERN ALSO WITH MOSTLY AFTERNOON SEABREEZE EFFECTS FROM HEATING THROUGH EARLY NEXT WEEK...THUS GIVING WAY TO LESS MOISTURE CONVERGENCE AND LIMITED COVERAGE OF SHOWERS AND THUNDERSTORMS OVER INLAND AREAS OF THE CWFA THROUGH SUN. BEST CHANCE FOR MEASURABLE RAIN WILL BE CLOSER TO THE COAST IN THE AFTERNOON MAINLY SHORT LIVED ALONG A WEAK SEABREEZE BOUNDARY EACH AFT. BY 12Z MON MID TO UPPER WESTERLY FLOW SHIFTS SOUTHWARD ACROSS THE LOWER MS RIVER AND CENTRAL GULF STATES IN RESPONSE TO NEXT IMPULSE MOVING EAST OF THE CENTRAL PLAINS LATE SUN NIGHT THROUGH EARLY TUES. DUE TO THE BROAD SFC RIDGE ACROSS THE DEEP SOUTH OVER THE WEEKEND INTO EARLY NEXT WEEK MOISTURE RETURN OUT AHEAD OF THIS NEXT SYSTEM LOOKS TO BE MUCH LESS THAN EARLIER IN THE WEEK. AS THIS MAIN IMPULSE SHIFTS NORTHEAST OF THE REGION BY MON EVE A WEAK SFC BOUNDARY IS NOTED IN THE GUIDANCE DROPPING SOUTH TO THE CENTRAL GULF COAST BY LATE MON NIGHT OR EARLY TUE MORNING. WILL STAY CLOSE TO THE CURRENT FORECAST TEMPS AND POPS IN THE EXTENDED GRIDS THROUGH EARLY NEXT WEEK NUDGING MOSTLY UP IF NEEDED DUE TO SUBSIDENCE AND CONSISTENCY WITH SURROUNDING OFFICES. /32 && .AVIATION...WE WILL KEEP THE THUNDERSTORM ACTIVITY NORTH OF THE KMOB...KBFM AND KPNS OPERATING AREAS FOR THE REST OF TODAY. SCATTERED TO OCCASIONALLY BROKEN DECK OF CU WILL PERIODICALLY BRING CIGS DOWN TO AROUND 3500 FT AGL. WILL SEE SOME PATCHY FOG TONIGHT...MORE-SO INLAND AND WILL KEEP VISIBILITIES AT OR ABOVE MVFR TONIGHT BUT WILL LIKELY BRING IN A PERIOD OF LOW CLOUDS AND CIGS DOWN TO IFR DURING THE PREDAWN HOURS. /05 && .MARINE...SOUTH TO SOUTHWEST WINDS WILL CONTINUE THROUGH EARLY NEXT WEEK AS HIGH PRESSURE REMAINS CENTERED OFF THE MID ATLANTIC COAST AND EASTERN GULF OF MEXICO. NEARSHORE WINDS WILL BE A BIT LIGHTER OVER THE WEEKEND AS THE SURFACE RIDGE BUILDS IN FROM THE EAST. /05 && .FIRE WEATHER...DRIER CONDITIONS ARE EXPECTED THROUGH THE WEEKEND AS HIGH PRESSURE BETTER SUBSIDENCE MOVES IN FROM THE WEST. AS A RESULT AFTERNOON RELATIVE HUMIDITIES WILL FALL TO AROUND 40 PERCENT OVER INLAND AREAS OF THE FORECAST AREA THROUGH SUNDAY WITH GENERALLY A LIGHT SOUTHERLY FLOW.
