AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
500 AM CDT SAT APR 5 2008

.SHORT TERM...INTENSE RAINFALL OVERNIGHT FOR SOME FOLKS...ESPECIALLY
ACROSS GEORGE AND STONE COUNTIES IN MISSISSIPPI AND THE NORTHERN
PORTIONS OF MOBILE AND BALDWIN COUNTIES IN ALABAMA. NEARLY
CONTINUOUS RAIN TRAINED OVER THE SAME AREA FOCUSED IN THE VICINITY
OF A PERSISTENT SHALLOW SW-NE ORIENTATED BOUNDARY ACROSS OUR
FORECAST AREA...WITH GULF MOISTURE FEEDING INTO THE SYSTEM BY A LOW
LEVEL JET OVER-RUNNING THE BOUNDARY LAYER. AREA RAINFALL REPORTS AND
RADAR RAINFALL ESTIMATES INDICATE WIDESPREAD THREE TO SIX
INCHES...WITH HEAVIER BANDS OF SEVEN TO TEN INCHES. REPORTS OF
FLOODING...WITH SOME EVACUATIONS AND STRANDED VEHICLES CONTINUE TO
COME IN.

THIS SCENARIO WILL CONTINUE THROUGH THE MORNING HOURS...WITH AN
ADDITIONAL TWO TO FOUR INCHES POSSIBLE ACROSS OUR SOUTHERN AND
EASTERN ZONES. MANY DAILY RAINFALL RECORDS WILL LIKELY BE EXCEEDED
TODAY. THE RAIN WILL SLOWLY TAPER OFF FROM NORTHWEST TO SOUTHEAST
THROUGHOUT THE DAY AS A COLD FRONT MOVES THROUGH. ISOLATED SHOWERS
MAY LINGER INTO THE EARLY EVENING HOURS ACROSS THE WESTERN FLORIDA
PANHANDLE. WITH THE RAIN-COOLED AIR AND CLOUDY SKIES MOST OF THE
DAY...I GENERALLY WENT WITH THE 2M NAM TEMPS...OR ABOUT TWO TO THREE
DEGREES BELOW MAV GUID FOR TODAY MAXIMUM. /22

&&

.LONG TERM...BY 12Z SUN BROAD MID TO UPPER LEVEL TROF CONTINUES TO
MOVE SLOWLY EAST OVER THE CENTRAL CONUS AND MS RIVER VALLEY WITH
WEAK HIGH PRESSURE NEAR THE SFC BUILDING OVER THE SE CONUS AND
CENTRAL GULF STATES. TO THE SOUTH COLD FRONT STALLS OVER THE NORTH
CENTRAL GULF WITH ANOTHER WAVE OF LOW PRESSURE TRACKING EASTWARD
ALONG THE FRONT SOUTH OF THE AL AND NWFL COAST. LATEST GFS SOLUTION
LOOKS TO BE OVERDONE WITH THIS SYSTEM RESULTING IN MORE CONVECTIVE
FEEDBACK ISSUES IN THE THESE AREAS. THE CURRENT NAM SOLUTION ALSO
DEPICTS THIS WEAK LOW ALONG THE FRONT...LIKELY A BETTER
REPRESENTATION OF WHAT IS TO OCCUR LATER IN THE WEEKEND. AS A RESULT
HAVE KEPT A SMALL POP ALONG THE COAST IN THE MORNING WITH BETTER
POPS ALONG BOUNDARY LATE SUN AFT AND SUN EVENING GENERALLY OVER
INLAND AREAS OF SOUTH CENTRAL AL AND NWFL FL AFTER THE WEAK BOUNDARY
RETROGRADES INLAND LATER IN THE DAY. THE CURRENT GFS SOLUTION KEEPS
THIS BOUNDARY MOSTLY OFFSHORE WITH MOST OF THE PRECIP SUN AFT AND
EVE REMAINING OVER THE GULF. BY SUN NIGHT SFC RIDGE TO THE NE BUILDS
SSWESTWARD GIVING WAY TO A BETTER THERMAL/MOISTURE GRADIENT OVER
MUCH OF THE CWFA MON THROUGH EARLY TUE. BY LATE TUES INTO WED RETURN
FLOW INCREASE ALONG THE COAST MOSTLY IN RESPONSE TO SFC RIDGE
BUILDING SOUTHWARD ALONG THE ATLANTIC SEABOARD AND NEXT VIGOROUS
SHORTWAVE EJECTING EASTWARD AHEAD OF THE MAIN UPPER TROF STILL TO
THE WEST. THIS PATTERN WILL RESULT IN BETTER RAIN CHANCES...MOSTLY
IN THE FORM SHOWERS AND THUNDERSTORMS...FOR MUCH OF THE CWFA LATE
WED INTO THU. BY LATE THU INTO FRI MID TO UPPER TROF OVER THE
CENTRAL CONUS BEGINS TO MOVE BETTER TO THE EAST WITH A SFC COLD
FRONT MOVING ACROSS THE CWFA LATE FRI INTO SAT. SHOWERS AND
THUNDERSTORMS CAN BE EXPECTED ALONG THE FRONT. WILL CONTINUE TO USE
THE CURRENT 00Z MEX GUIDANCE FOR TEMPS IN THE EXTENDED PDS.
/32

&&

.MARINE...MODERATE TO STRONG SOUTHERLY WINDS WILL CONTINUE THIS
MORNING AHEAD OF A COLD FRONT APPROACHING FROM THE NORTHWEST.
SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS...MAINLY OVER INLAND
AREAS THIS MORNING...WILL MOVE OFFSHORE AS THE FRONT MOVES THROUGH.
A LIGHT TO MODERATE NORTHERLY WIND FLOW WILL FOLLOW IN THE WAKE OF
THE FRONT LATER TODAY THROUGH EARLY SUNDAY...AND THE BECOME EAST TO
SOUTHEAST AND INCREASE IN THE AFTERNOON. EASTERLY WINDS AND SEAS
WILL BUILD SLIGHTLY BY EARLY NEXT WEEK AS HIGH PRESSURE STRENGTHENS
ALONG THE EASTERN SEABOARD. /22

&&

.FIRE WEATHER...AFTERNOON RELATIVE HUMIDITIES WILL FALL TO THE MID
30 PERCENT RANGE FOR INLAND AREAS OF ALABAMA ON SUNDAY THEN CLIMBING
TO THE 50 TO 60 PERCENT RANGE FOR THE REMAINDER OF THE WEEK.
OTHERWISE...NO CONCERNS. /32

&&

.HYDROLOGY...AN EXTENDED PERIOD OF HEAVY RAINFALL HAS PRODUCED FLASH
FLOODING THIS MORNING...ESPECIALLY IN THE MOBILE METRO AREA EAST OF
I-65. RFC HOURLY PRECIP ANALYSIS INDICATES STORM TOTAL RAINFALL
ACCUMULATIONS OF 2 TO 8 INCHES IN A CORRIDOR EXTENDING FROM STONE
AND GEORGE COUNTIES IN MS EASTWARD THROUGH CENTRAL MOBILE AND
NORTHERN BALDWIN COUNTIES...WITH THE HIGHEST TOTALS OVER CENTRAL
MOBILE COUNTY. ANOTHER BAND OF HEAVY RAIN IS ALREADY APPROACHING
THESE AREAS SO FLASH FLOODING PROBLEMS WILL LIKELY PERSIST WELL INTO
THE MORNING HOURS.

WITH REGARDS TO AREA RIVERS...ATTM NONE OF THE MAJOR WATERWAYS IN
OUR HSA ARE FORECAST TO REACH FLOOD STAGE...BUT A FEW OF THE RIVERS
AND CREEKS IN THE FLORIDA PANHANDLE MAY APPROACH FLOOD STAGE. ALSO
THERE ARE SOME CONCERNS ABOUT FLOODING ALONG BAYOU SARA DUE TO VERY
HEAVY RAINFALL OVERNIGHT. WE WILL CONTINUE TO CLOSELY MONITOR THE
LATEST GAGE HEIGHT DATA FOR QUICK RISES AND ISSUE WARNINGS IF THEY
BECOME NECESSARY. TO MONITOR THE LATEST RIVER STATEMENTS...SEE THE
LATEST HYDROLOGIC STATEMENT (PRODUCT ID FGUS85/RVSMOB). /15

.DAY ONE...TODAY AND TONIGHT.

A BAND OF PERSISTENT HEAVY RAIN FELL LAST NIGHT FROM GEORGE AND
STONE COUNTIES IN MISSISSIPPI...ACROSS MOBILE AND BALDWIN COUNTIES
IN ALABAMA...AND INTO NORTHERN ESCAMBIA COUNTY IN FLORIDA. THESE
RAINS HAVE RESULTED IN WIDESPREAD INUNDATION...REPORTS OF LIFE
THREATENING FLASH FLOODING...AND SOME MODERATE RIVER FLOODING. THE
FLOODING THREAT WILL REMAIN THIS MORNING AS PERIODS OF HEAVY RAIN
CONTINUE TO TRAIN OVER PORTIONS OF THIS SAME AREA...WITH AN
ADDITIONAL ONE TO TWO INCHES POSSIBLE. PONDING OF WATER IN POORLY
DRAINED AREAS OR POSSIBLE ISOLATED INCIDENTS OF LOCALIZED FLASH
FLOODING MAY OCCUR ACROSS THE REMAINDER OF THE OUTLOOK AREA.

OCCASIONAL STRONG WINDS WILL OCCUR THROUGH EARLY AFTERNOON PROVIDING
A THREAT TO MARINERS OPERATING ON THE OFFSHORE WATERS AND AREA BAYS.
IN ADDITION...A FEW THUNDERSTORMS ALONG THE COASTAL SECTIONS AND
OVER THE GULF WATERS MAY BECOME STRONG WITH GUSTY SURFACE WINDS. THE
AREAS OF RAIN AND THUNDERSTORMS WILL BEGIN TO TAPER OFF BY MIDDAY AS
THE SYSTEM MOVES EASTWARD.

THERE IS AN INCREASED RISK FOR DANGEROUS RIP CURRENTS ALONG AREA
BEACHES TODAY.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.

AN INCREASING SOUTHEASTERLY WIND AND BUILDING SEAS TUESDAY THROUGH
THURSDAY WILL BRING AN INCREASED RISK FOR BOATERS ON THE COASTAL
WATERS AND AN INCREASED RISK OF DANGEROUS RIP CURRENTS ALONG AREA
BEACHES. A COLD FRONT WILL ADVANCE SOUTHEAST THROUGH THE OUTLOOK
AREA ON FRIDAY...BRINGING THE POTENTIAL OF STRONG TO SEVERE
THUNDERSTORMS.

.SPOTTER INFORMATION STATEMENT...

STORM SPOTTERS AND EMERGENCY MANAGEMENT ACROSS THE SOUTHERN AND
EASTERN PORTIONS OF THE OUTLOOK AREA WILL BE NEEDED TODAY DUE TO A
HEIGHTENED THREAT OF FLASH FLOODING.
