AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOBILE AL
447 AM CDT SAT JUN 9 2012

.SHORT TERM [TODAY THROUGH SUNDAY NIGHT]...THE EARLY MORNING WATER VAPOR
SATELLITE IMAGERY LOOP CONTINUES TO SHOW A SLOW MOVING UPPER LEVEL
LOW CENTERED IN THE VICINITY OF THE UPPER TEXAS COAST. A VERY MOIST
SOUTH TO SOUTHWEST FLOW ALOFT CONTINUES TO SPREAD ACROSS THE GULF
COAST IN ADVANCE OF THIS FEATURE EARLY THIS MORNING...WHILE A WEAK
STATIONARY FRONTAL BOUNDARY REMAINS DRAPED ALONG THE NORTHERN GULF
OF MEXICO. A LARGE BAND OF MODERATE TO HEAVY RAIN SHOWERS WITH
ISOLATED EMBEDDED THUNDERSTORMS HAS CONTINUED TO DEVELOP OVER THE
NORTHERN GULF OF MEXICO NEAR THIS BOUNDARY EARLY THIS MORNING...
WITH PRECIPITATION SPREADING INLAND ACROSS CENTRAL AND SOUTHERN
PORTIONS OF THE FORECAST AREA.

THE OVERALL SURFACE AND UPPER AIR PATTERN WILL CONTINUE TO FAVOR A
FAIRLY WIDESPREAD HEAVY RAIN EVENT ACROSS MUCH OF THE FORECAST AREA
TODAY AND TONIGHT. THE UPPER LEVEL LOW WILL SLOWLY MOVE EASTWARD
INTO THE VICINITY OF LOUISIANA AND ARKANSAS THROUGH TONIGHT...WITH A
MOIST AND DIFFLUENT UPPER FLOW PATTERN PERSISTING ACROSS THE GULF
COAST STATES ON THE EAST SIDE OF THIS FEATURE. THE STATIONARY
FRONTAL BOUNDARY IS ALSO EXPECTED TO REMAIN IN THE VICINITY OF THE
GULF COAST THROUGH TONIGHT. ABUNDANT MOISTURE AND LIFT WILL CONTINUE
TO GENERATE NUMEROUS SHOWERS AND A FEW THUNDERSTORMS ACROSS THE
REGION THROUGH TONIGHT. THE 09/00Z SLIDELL LA SOUNDING DEPICTED HIGH
ATMOSPHERIC MOISTURE CONTENT LAST EVENING WITH PRECIPITABLE WATER (PW) VALUES
JUST OVER 2.1 INCHES. SHORT TERM SOLUTIONS ARE ALL IN AGREEMENT WITH
SPREADING THESE PW VALUES OF 2.0 TO 2.1 INCHES INLAND ACROSS ALL OF
OUR FORECAST TODAY AND TONIGHT...SO VERY HEAVY RAINFALL WILL LIKELY
ACCOMPANY THE STRONGER SHOWERS AND THUNDERSTORMS. THE MOBILE WSR-88D
PRECIPITATION ESTIMATES INDICATE THAT HEAVY RAINFALL MAINLY OCCURRED
WITHIN A NARROW ZONE FROM FAR SOUTHEAST MISSISSIPPI THROUGH LOWER
PORTIONS OF MOBILE AND BALDWIN COUNTIES YESTERDAY. THESE LOCATIONS
WILL HAVE TO BE MONITORED FOR POTENTIAL FLOODING PROBLEMS TODAY. IF
HEAVY RAINS CONTINUE TO SPREAD OVER THESE AND OTHER LOCATIONS...LATER
SHIFTS MAY HAVE TO CONSIDER A FLOOD WATCH FOR PORTIONS OF THE REGION.
RAINFALL TOTALS OF 1 TO 2 INCHES LOOK TO BE COMMON ACROSS THE REGION
THROUGH TONIGHT...WITH ISOLATED AMOUNTS OF 4 INCHES OR MORE.
PRECIPITATION CHANCES WERE BUMPED TO 80-90 PERCENT COVERAGE ACROSS
ALL OF THE FORECAST AREA THROUGH EARLY THIS EVENING...WITH COVERAGE
DECREASING A BIT THIS EVENING INTO TONIGHT...THOUGH RAIN WILL STILL
BE LIKELY. RAIN AND CLOUD COVER SHOULD KEEP TEMPERATURES A BIT BELOW
NORMAL TODAY...AND GUIDANCE NUMBERS GENERALLY LOOKED GOOD.

THE WET MICROBURST RISK FOR TODAY IS LOW. /21

SUNDAY AND SUNDAY NIGHT...UPPER LEVEL LOW OVER THE LOWER MISSISSIPPI
RIVER VALLEY INTO THE WESTERN GULF SUNDAY...PROGGED TO BEGIN PHASING
WITH ENERGY MOVING EASTWARD ACROSS THE NORTHERN HIGH PLAINS SUNDAY
NIGHT. COASTAL SURFACE FRONTAL BOUNDARY BEGINS TO BE ABSORBED BY
SYNOPTIC SCALE SOUTHERLY FLOW. REGARDLESS OF THE WEAKENING SURFACE
BOUNDARY...THE FORECAST AREA REMAINS ON THE FAVORED EAST => WET SIDE OF
THE HIGH LEVEL TROF AXIS. DEEP LAYER LIFT COMBINES WITH PRECIPITABLE
WATERS AVERAGING NEAR 2 INCHES...FOR LIKELY TO CATEGORICAL
PROBABILITIES OF SHOWERS/STORMS TO REMAIN IN THE FORECAST. LOCALLY
HEAVY RAINS CONTINUE TO BE POSSIBLE.

.LONG TERM [MONDAY THROUGH FRIDAY]...UPPER LEVEL TROF AXIS FROM THE
TENNESSEE VALLEY INTO THE CENTRAL GULF COAST ON MONDAY...PHASES WITH ENERGY
MOVING EASTWARD OVER THE MID MISSISSIPPI RIVER VALLEY AND UPPER
MIDWEST. THIS WOULD CAUSE AN EASTWARD MOVEMENT TO THE TROF AXIS...MORE
INTO THE SOUTHEAST STATES BY TUESDAY. BROAD TROF AXIS REMAINS
POSITIONED THERE WEDNESDAY THROUGH FRIDAY. AT THE BASE OF THE
TROF...DEEP LAYER MOISTURE HANGS TOUGH WITH (PRECIPITABLE WATER
VALUES 1.7-1.9 INCHES) COVERING A SUBSTANTIAL AREA FROM THE MID
ATLANTIC INTO THE CENTRAL GULF COAST THROUGH THE UPCOMING WEEK. A
SERIES OF MID LEVEL IMPULSES IN THE EVOLVING HIGHER LEVEL NORTHWEST
FLOW ON THE WEST SIDE OF THE TROF WILL CONTINUE TO OPERATE ON HIGH
MOISTURE CONTENT AIR. THUS...MODEST LIFT AND A CONTINUED CHANCE OF
SHOWERS/STORMS WILL BE ADVERTISED DURING THE MEDIUM RANGE. WEAK
MESOSCALE BOUNDARIES THAT SET UP OVER THE REGION WILL ALSO PLAY A
ROLE IN BEING A FOCUS FOR STORM DEVELOPMENT. SURFACE HIGH PRESSURE
OVER THE GULF NEXT WEEK WILL BRING A GENERAL...LIGHT WEST/NORTHWEST
FLOW DURING THE NIGHT PERIODS WHICH TAKE ON A SOUTHWEST COMPONENT IN
THE AFTERNOONS MAINLY NEAR THE COAST. DAILY HIGHS WILL NOT BE FAR OFF
THE MARK FROM NORMAL...AROUND 90. LOW TEMPERATURES 68-72 OVER THE
INTERIOR TO MID 70S BEACHES. /10

&&

.AVIATION [12Z KMOB/KBFM/KPNS TERMINAL FORECAST ISSUANCE]...
MVFR CEILINGS AND WIDESPREAD SHRA WILL REMAIN OF IMPACT ACROSS THE
LOCAL TERMINALS THROUGH THE DAY...WITH LOCALIZED IFR CEILINGS THIS
MORNING. A FEW TSRA WILL ALSO BE POSSIBLE. VISIBILITY MAY BE
RESTRICTED TO IFR LEVELS AT TIMES WITHIN THE HEAVIER SHRA/TSRA THAT
DEVELOP. EAST WINDS AROUND 10 KNOTS THIS MORNING WILL BECOME
SOUTHEAST TO SOUTH AT 10-15 KNOTS WITH HIGHER GUSTS LATER THIS
MORNING INTO THIS AFTERNOON. /21

&&

.MARINE...SURFACE LOW PRESSURE WILL CONTINUE TO DEEPEN ACROSS THE
WESTERN GULF OF MEXICO TODAY...WHILE SURFACE HIGH PRESSURE RIDGING
EXTENDS ALONG THE EAST COAST. A TIGHTENING SURFACE PRESSURE GRADIENT
BETWEEN THESE TWO FEATURES WILL RESULT IN MODERATE TO STRONG
SOUTHEASTERLY TO SOUTHERLY WINDS ACROSS THE MARINE AREA THROUGH
SUNDAY...AND SMALL CRAFT SHOULD CONTINUE TO EXERCISE CAUTION. WIND
SPEEDS AND BUILDING SEAS MAY NECESSITATE THE NEED FOR A SMALL CRAFT
ADVISORY BY TONIGHT. WINDS WILL BECOME SOUTHWESTERLY AND DECREASE IN
SPEED EARLY TO MIDDLE OF NEXT WEEK AS SURFACE RIDGING BUILDS OVER THE
EASTERN GULF OF MEXICO.

A HIGH RISK OF RIP CURRENTS WILL ALSO CONTINUE ALONG AREA BEACHES
THROUGH THIS EVENING. /21

CONDITIONS IN PLACE. /10
