AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MOBILE AL
719 PM CDT SAT APR 18 2015

.AVIATION...
19.00Z KMOB/KBFM AND KPNS TAF CYCLE...
AN AREA OF RAIN SHOWERS WITH EMBEDDED THUNDERSTORMS OVER THE GULF OF
MEXICO WILL SPREAD INLAND ACROSS THE NORTHERN GULF COASTAL REGION
THIS EVENING...WITH MVFR CEILINGS DEVELOPING. PATCHY FOG WILL DEVELOP
AFTER MIDNIGHT BETWEEN THE PASSING RAIN SHOWERS...SO THERE COULD BE
PERIODS OF IFR VISIBILITIES AND CEILINGS DEVELOPING MAINLY BETWEEN
18.10Z THROUGH 18.14Z. AREAS OF LIGHT RAIN WITH EMBEDDED MODERATE
THUNDERSTORMS WILL MOVE INTO THE AREA AGAIN FROM THE SOUTHWEST LATE
TONIGHT INTO SUNDAY MORNING...SO ADDED A PROB30 GROUP FROM 19.09Z TO
19.15Z. THE FOG WILL LIFT QUICKLY SUNDAY MORNING...WITH CEILINGS
LIFTING TO MVFR CRITERIA BY LATE MORNING. WINDS WILL ALSO INCREASE
FROM THE SOUTH TO SOUTHWEST AT 10 TO 15 KNOTS ON SUNDAY. /22

&&

.PREV DISCUSSION... /ISSUED 411 PM CDT SAT APR 18 2015/

SHORT TERM...(TONIGHT THROUGH MONDAY NIGHT)...FOR TONIGHT THROUGH
SUNDAY...AN UPPER LOW OVER THE CENTRAL
PLAINS BEGINS TO BE ABSORBED BY A LONGWAVE TROF WHICH EVOLVES OVER
THE CENTRAL STATES.  A SERIES OF STRONG SHORTWAVES WILL MOVE ACROSS
THE REGION IN THE SOUTHWEST FLOW ALOFT AND BRING HIGH RAIN CHANCES
TO THE AREA DUE TO BOTH AN MCS...MESOSCALE CONVECTIVE
SYSTEM...EXPECTED TO TRAVERSE THE MARINE AREA...AND ASSOCIATED WITH
A SURFACE LOW WHICH DEVELOPS OVER THE LOWER MISSISSIPPI RIVER VALLEY
AND MOVES WELL NORTH OF THE AREA.  STORM SCALE INTERACTIONS AND
SUB-SYNOPTIC FEATURES HAVE IMPACTED THE FORECAST SUCH AS THE
LINGERING AREA OF CONVECTION OVER THE MARINE AREA...A REMNANT OF AN
OVERNIGHT MCS...AND ANOTHER MCS WHICH APPEARS TO BE CURRENTLY
DEVELOPING SOUTH OF LOUISIANA.  THE LATTER MCS HAS DEVELOPED ON A
850 MB THETA-E RIDGE IN A REGION OF DIFFLUENT 850-300MB
THICKNESS...AND BASED ON THE PLACEMENT OF THESE FEATURES...EXPECT
THE MCS TO TRANSLATE GENERALLY EASTWARD OVERNIGHT AND EVENTUALLY
INTO THE NORTHEASTERN GULF.

WITH ABUNDANT CONVECTION EXPECTED OVER THE MARINE AREA THROUGH MUCH
OF THE PERIOD...THIS WILL SIGNIFICANTLY LIMIT SURFACE BASED
INSTABILITY OVER THE LAND PORTION OF THE AREA AND DO NOT SEE MUCH OF
A SEVERE STORM POTENTIAL AT LEAST THROUGH SUNDAY MORNING.  BETTER
INSTABILITY DOES DEVELOP LATER IN THE DAY ON SUNDAY...BUT FORCING IS
WEAKER OR NEGATIVE WHICH WILL LIMIT CONVECTIVE DEVELOPMENT
SUFFICIENTLY THAT AM NOT EXPECTING MUCH OF A SEVERE STORM RISK ON
SUNDAY EITHER AS THE 850 MB FLOW WILL BE SOUTHWESTERLY ALONG WITH
THE SURFACE FLOW AND NOT PARTICULARLY STRONG.  THE EXCEPTIONS TO
THIS ARE POSSIBLY OVER THE NORTHWEST FLORIDA PANHANDLE LATE TONIGHT
INTO EARLY SUNDAY MORNING SHOULD THE MCS TRANSLATE FURTHER NORTHWARD
ALLOWING FOR BETTER SURFACE BASED INSTABILITY...AND WILL NEED TO
MONITOR.

EXPECT CURRENTLY NEGLIGIBLE/ISOLATED PATCHES OF LIGHT RAIN TO BECOME
MORE WIDESPREAD OVERNIGHT AS THE LOUISIANA MARINE AREA MCS
STRENGTHENS...AND AS ADDITIONAL CONVECTION DEVELOPS FURTHER INLAND
OVER THE AREA. HAVE GONE WITH LIKELY POPS FOR MUCH OF THE AREA THIS
EVENING...EXCEPT FOR GOOD CHANCE POPS OVER SOUTH CENTRAL
ALABAMA...THEN CATEGORICAL POPS FOLLOW FOR ABOUT THE SOUTHERN HALF OF
THE AREA OVERNIGHT WITH LIKELY POPS ELSEWHERE AS THE EXPANDING MCS
ADVANCES FURTHER EASTWARD. QPF AMOUNTS LOOKS TO BE INCREASING
OVERNIGHT MAINLY OVER THE SOUTHERN PORTION OF THE AREA...THEN THE
HEAVIER AMOUNTS LOOK CONFINED TO ROUGHLY EAST OF I-65 SUNDAY MORNING
AS SUBSIDENCE BEGINS TO WORK INTO THE WESTERN PORTION OF THE AREA.
WILL HAVE LIKELY/CATEGORICAL POPS ROUGHLY EAST OF I-65 SUNDAY MORNING
THEN CHANCE POPS FOR THE REMAINING PORTION...WITH CHANCE POPS FOR THE
ENTIRE AREA SUNDAY AFTERNOON.

HAVE KEPT THE FLASH FLOOD WATCH IN AFFECT ACROSS THE AREA
TONIGHT...THEN HAVE TRIMMED TO WATCH TO JUST BE IN EFFECT ROUGHLY
ALONG AND EAST OF I-65 SUNDAY MORNING AS QPF AMOUNTS ARE TOO LOW TO
SUPPORT THE WATCH ELSEWHERE. /29

SUNDAY NIGHT...A STRONG SHORTWAVE SWEEPS AROUND THE BASE OF THE
CLOSED LOW OVER THE US/CA BORDER...PUSHING A SURFACE FRONT TOWARDS
THE LOWER MISS RIVER. GUIDANCE IS ADVERTISING SIGNIFICANT DRY
SLOTTING AHEAD OF THE FRONT...WITH A DECREASE IN POPS OVER THE FA.
WITH DAYTIME HEATING SUNDAY ALLOWING FOR A FEW STORMS TO BECOME
STRONG TO SEVERE...AM EXPECTING THIS TO BLEED INTO EARLY SUNDAY
EVENING. AM EXPECTING THIS ACTIVITY TO DECREASE WITH THE SETTING SUN
AND PRETTY MUCH GONE BY MIDNIGHT.

MONDAY INTO MONDAY NIGHT...THE SHORTWAVE SWEEPS NORTHEAST AHEAD OF
THE BORDER UPPER LOW...PUSHING THE FRONT ACROSS THE FA LATE MONDAY
INTO MONDAY EVENING...THEN STALLING OVER THE CENTRAL GULF BY TUESDAY
MORNING. SURFACE HIGH PRESSURE MOVES QUICKLY EAST FROM OVER THE
SOUTHERN PLAINS TO OVER THE LOWER MISS RIVER VALLEY...EASING THE
POST-FRONTAL WINDS (WHICH AM NOT EXPECTING TO BE THAT STRONG WITH THE
DRIVING DYNAMICS WELL NORTH OF THE FA)...SO A PLEASANT TUESDAY
MORNING IS EXPECTED. ANOTHER SEASONABLE WARM DAY MONDAY IS
EXPECTED...WITH TEMPS DROPPING TO AROUND SEASONAL MONDAY NIGHT.

LONG TERM...(TUESDAY ON)...TUESDAY THROUGH WEDNESDAY...THE UPPER LOW
OVER THE US/CA PLAINS MENDERS EASTWARD TO OVER THE GREAT
LAKES...THEN STALLS. THE PIECES OF ENERGY SWINGING AROUND THE BAS OF
THIS SYSTEM PUSH THE SURFACE HIGH FROM OVER THE LOWER MISS RIVER
VALLEY TO OFF THE ATLANTIC COAST. A SURFACE RIDGE REMAINS OVER THE
NORTHER GULF COAST...WITH ONSHORE FLOW RETURNING TO THE FA BY
WEDNESDAY EVENING. TUESDAY AND TUESDAY NIGHT SEE TEMPS DROP TO A BIT
BELOW SEASONAL(70S TUESDAY...50S TUESDAY NIGHT)....BUT BEGIN TO
MODERATE BACK UP WEDNESDAY....WITH TEMPS IN THE 80S RETURNING FOR
WEDNESDAY.

WEDNESDAY NIGHT THROUGH THURSDAY...A LOBE UP ENERGY SWIRLS AROUND
THE BASE OF THE GREAT LAKES UPPER LOW...PUSHING A WEAK BOUNDARY
TOWARDS...THEN PARTIALLY OVER...WITH THE BOUNDARY STALLING OVER THE
NORTHERN HALF OF THE FA BY THURSDAY EVENING. CONTINUE TO REBOUND TO
SEASONABLY WARMS VALUES WITH MOST OF THE FA UNDER ONSHORE FLOW. AS
THE BOUNDARY WORKS ITS WAY NEAR AND OVER THE FA...RAIN AND
THUNDERSTORMS RETURN TO THE AREA...WITH THE BEST CHANCE BEING
THURSDAY.

THURSDAY NIGHT THROUGH SATURDAY NIGHT...UPPER ENERGY THAT HAD
ORGANIZED INTO A CLOSED LOW OVER THE DESERT SOUTHWEST BREAKS DOWN AND
GETS DRAWN EAST BY MORE ENERGY SWEEPING AROUND THE GREAT LAKES
SYSTEM. GUIDANCE AGREES ON A SURFACE LOW FORMING AND MOVING EAST
FRIDAY THROUGH FRIDAY NIGHT. DISAGREEMENT IS WHERE. THE ECMWF IS
ADVERTISING THE LOW FORMING OVER THE OK/KS BORDER AND MOVING EAST-
SOUTHEAST TO OVER THE MS DELTA BY SATURDAY MORNING. THE GFS TAKES A
MORE SOUTHERLY/FASTER PATH...WITH DEVELOPMENT OVER TX AND MOVING EAST
NORTH OF THE NORTHERN GULF COAST BEFORE ENDING UP OVER THE FA BY
SATURDAY MORNING. UP TO THIS POINT...BOTH ARE ADVERTISING RAIN
CONTINUING...WITH THE GFS IS ADVERTISING A COOLER SCENARIO...THOUGH
THAN THE ECMWF. HAVE TRIED BEST TO BLEND...WITH EITHER SCENARIO
POSSIBLE.

SATURDAY AND SATURDAY NIGHT...BOTH ARE ADVERTISING THE SYSTEM'S POST-
SYSTEM FRONT MOVING ACROSS THE FA SATURDAY AND THE FA DRYING OUT. GFS
IS ADVERTISING A STRONGER POST SYSTEM PUSH OF NORTHERLY AIR THAN THE
ECMWF. HAVE WENT IN THE MIDDLE FORE THE FORECAST...WITH THE RESULT
BEING TEMPS AROUND TO A BIT BELOW SEASONAL THE LAST TWO PERIODS OF
THE FORECAST.

MARINE...A LIGHT TO OCCASIONALLY ONSHORE FLOW PREVAILS THROUGH
SUNDAY. A COLD FRONT APPROACHES THE AREA FROM THE WEST SUNDAY NIGHT
INTO MONDAY AND MOVES ACROSS THE MARINE AREA MONDAY NIGHT WITH A
LIGHT TO MODERATE OFFSHORE FLOW IN THE WAKE OF THE FRONT. AN ONSHORE
FLOW RETURNS BY WEDNESDAY AS HIGH PRESSURE MOVES ACROSS THE REGION IN
THE WAKE OF THE FRONT. WINDS AND WAVES WILL BE HIGHER IN AND AROUND
SHOWERS AND THUNDERSTORMS. /29
