AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NEW ORLEANS LA
1152 AM CDT FRI AUG 10 2012

.AVIATION...
FRONTAL ZONE IN THE AREA SHOULD SERVE AS FOCUS FOR CONVECTION THAT
WILL IMPACT TERMINALS WITH MVFR TO IFR REDUCTIONS IN CEILINGS AND
VISIBILITY FOR 30-40 MINUTE WINDOWS. LARGE CONCERN FOR WET MICROBURST
THAT MAY GET 40-50 MPH TODAY DUE TO DRY AIR ALOFT WORKING TO
SURFACE UNDER TALLER CB TODAY. PRIMARY PERIOD OF WET BURST
POTENTIAL WILL BE BETWEEN 18Z-23Z THOUGH OVERALL CONVECTION MAY
LINGER BEYOND 11/00Z.   24/RR

&&

.PREV DISCUSSION... /ISSUED 814 AM CDT FRI AUG 10 2012/

UPDATE...

SOUNDING DISCUSSION...

NO PROBLEMS WITH THE FLIGHT THIS MORNING. A VERY UNSTABLE SOUNDING
WITH PLENTY OF LOW LEVEL MOISTURE WITH A PW OF 2.04 INCHES AND AN
LI OF -9.8. A DRY AND COOL POCKET ALOFT ABOVE 55O MB WITH
TEMPERATURES AS LOW AS -7 CELSIUS AT 500 MB. AN EXTREMELY HIGH
CAPE OF 5331. WITH THIS IN MIND THE POTENTIAL FOR STRONG DOWNBURST
AND SMALL HAIL IS POSSIBLE AS STORMS FLARE UP LATER THIS MORNING
INTO EARLY AFTERNOON. A LIGHT TO MODERATE WESTERLY FLOW IN THE
LOWER TO MIDDLE LEVELS WITH A NORTHWESTERLY FLOW ALOFT.

PREV DISCUSSION... /ISSUED 347 AM CDT FRI AUG 10 2012/

SHORT TERM...

A VIGOROUS UPPER LEVEL TROUGH AXIS...AND ASSOCIATED SURFACE
FRONTAL BOUNDARY WILL SLIDE THROUGH THE FORECAST AREA TODAY AND
TONIGHT. WITH INCREASED FORCING ALOFT ASSOCIATED WITH THE TROUGH
AXIS...AND CONTINUED HIGH PW VALUES IN EXCESS OF 2 INCHES...EXPECT
TO SEE ANOTHER ROUND OF STRONG CONVECTION PRODUCING LOCALLY GUSTY
WINDS AND VERY HEAVY RAINFALL. RAINFALL RATES OF 1 TO 2 INCHES PER
HOUR CANNOT BE RULED OUT WITH THE STRONGEST CONVECTION. WITH
LITTLE IN THE WAY TO INHIBIT CONVECTIVE DEVELOPMENT WITH WENT WITH
LIKELY POPS FOR THE DAY. POPS WILL TRAIL OFF SIGNIFICANTLY OVER
THE COASTAL WATERS...WITH ONLY SCATTERED POPS EXPECTED DUE TO LESS
OVERALL INSTABILITY. HOWEVER...A FEW WATERSPOUTS WILL BE POSSIBLE
DURING THE MORNING AND EARLY AFTERNOON HOURS. THE CONVECTION WILL
BEGIN TO WANE BY LATE EVENING...AS OVERALL INSTABILITY VALUES
DECREASE.

HEADING INTO TOMORROW...STRONG DRY AIR ADVECTION WILL TAKE HOLD
ABOVE 700 MB. ADDITIONALLY...AS THE UPPER LEVEL TROUGH AXIS PULLS
TO THE EAST...STRONG NEGATIVE VORTICITY ADVECTION AND RESULTANT
SUBSIDENCE WILL BUILD IN ACROSS THE MID TO UPPER LEVELS. NORTHERN
ZONES WILL BE MOST IMPACTED BY THE DRY AIR ADVECTION AND INCREASED
CAPPING ALOFT...AND HAVE REMOVED POPS FROM THE FORECAST FOR
SOUTHWEST MISSISSIPPI FOR SATURDAY. ALONG THE I-12
CORRIDOR...ONLY ISOLATED CONVECTION IS EXPECTED. ALONG THE
COAST...THE WASHED OUT FRONTAL BOUNDARY WILL STILL BE IN
PLACE. INCREASED LOW LEVEL CONVERGENCE ALONG THE WEAK FRONTAL
BOUNDARY...COMBINED WITH HIGHER OVERALL PW VALUES WILL ALLOW FOR
SCATTERED CONVECTION THROUGH THE DAY ON SATURDAY. THIS WILL ALSO
TRANSLATE INTO THE OFFSHORE WATERS. TEMPERATURES WILL REMAIN
SEASONABLY WARM ON SATURDAY...BUT OVERALL HUMIDITY AND HEAT INDEX
VALUES WILL BE NOTICEABLY LOWER.

THE DRIER AND MORE STABLE AIRMASS WILL BE FIRMLY ENTRENCHED ACROSS
THE AREA BY SUNDAY. PW VALUES ARE EXPECTED TO PLUNGE TO 1.25
INCHES OR LOWER...AND STRONG CAPPING BETWEEN 850 AND 700MB WILL BE
IN PLACE. THIS WILL EFFECTIVELY PUT A DAMPER ON ANY CONVECTIVE
POTENTIAL...AND HAVE A DRY FORECAST IN PLACE FOR ALL OF THE
CWA...EXCLUDING THE OFFSHORE WATERS...WHERE SOMEWHAT HIGHER PW
VALUES WILL LINGER. THE DRIER AIRMASS...COMBINED WITH A SINKING
AIRMASS...WILL ALLOW FOR INCREASED TEMPERATURES ON SUNDAY. HIGHS
WILL CLIMB INTO THE MIDDLE 90S. HOWEVER...OVERNIGHT LOWS WILL ALSO
BE SIGNIFICANTLY COOLER...WITH READINGS FALLING INTO THE MIDDLE TO
UPPER 60S NORTH OF THE I-10 CORRIDOR.

LONG TERM...

MONDAY WILL BE A TRANSITIONAL DAY...AS THE STRONG RIDGING OVER THE
REGION BEGINS TO BREAK DOWN...AND MOISTURE ADVECTION TAKES HOLD IN
THE UPPER LEVELS. PW VALUES WILL INCREASE TO AROUND 1.75 INCHES BY
MONDAY AFTERNOON...AND OVERALL INSTABILITY WILL ALSO INCREASE.
CAPE VALUES WILL RISE TO AROUND 1200 J/KG BY MONDAY
AFTERNOON...WHICH SHOULD BE SUFFICIENT TO SPARK OFF A FEW
DIURNALLY INDUCED THUNDERSTORMS. HAVE INCLUDED A MENTION OF
ISOLATED AFTERNOON CONVECTION FOR MONDAY TO REFLECT THIS RISK. THE
CONVECTION WILL FORM ALONG ANY PRE-EXISTING MESOSCALE BOUNDARIES
SUCH AS SEABREEZE FRONTS AND LINGERING OUTFLOW BOUNDARIES.

TUESDAY THROUGH THURSDAY WILL BE MUCH MORE UNSETTLED...AS A WEAK
UPPER LEVEL TROUGH AXIS SLIDES THROUGH THE MIDWEST. THIS WEAK
SYSTEM WILL FORCE A FRONT INTO THE LOWER MISSISSIPPI VALLEY. THE
FRONT SHOULD SLOWLY DISSIPATE ACROSS THE FORECAST AREA BEGINNING
TUESDAY AND LINGERING INTO THURSDAY. AS THIS BOUNDARY STALLS OVER
THE REGION...CONTINUED MOISTURE ADVECTION ON THE BACK SIDE OF A
BROAD MID-LEVEL RIDGE OVER THE EASTERN GULF OF MEXICO WILL ALLOW
PW VALUES TO RISE BACK TO AROUND 2 INCHES. THE BOUNDARY WILL SERVE
AS A FOCUS FOR CONVECTIVE DEVELOPMENT EACH...WITH CONVECTION BEING
DIURNAL IN NATURE. HAVE BUMPED UP POPS FOR MIDWEEK INTO THE CHANCE
RANGE DUE TO THESE CONDITIONS. TEMPERATURES WILL REMAIN
SEASONABLE...WITH HIGHS IN THE LOWER 90S AND LOWS IN THE MIDDLE
70S EACH DAY.

AVIATION...
VFR CONDITIONS WILL PREVAIL THROUGH THE EARLY MORNING HOURS WITH THE
POSSIBLE EXCEPTION BEING AT SOME OF THE MORE FOG PRONE LOCATIONS
WHICH MAY EXPERIENCE A BOUT WITH LIGHT FOG PRIOR TO DAYBREAK...AND
MAYBE EVEN SOME LOW STATUS AT KMCB FOR A PERIOD OF TIME. SCATTERED
TO NUMEROUS SHOWERS AND THUNDERSTORMS ARE EXPECTED TO AFFECT ALL TAF
SITES TODAY. COASTAL SITES WILL BE AFFECTED STARTING BETWEEN 13Z AND
15Z...INLAND TAF SITES BETWEEN 15Z AND 17Z AND CONVECTION AFFECTING
ALL TAF SITES THROUGH THE AFTERNOON AND EARLY EVENING. 18

MARINE...
LIGHT SOUTH TO SOUTHWESTERLY FLOW WILL CONTINUE ACROSS THE MARINE
ZONES THROUGH TONIGHT AS THE SURFACE RIDGE OF HIGH PRESSURE TO THE
EAST EXTENDS WEST OF THE GULF. A COLD FRONT WILL PRESS SOUTH TOWARD
THE COASTAL WATERS LATE TONIGHT THROUGH SATURDAY. WEST WINDS WILL
REMAIN ELEVATED UP TO 15 KNOTS ON EASTERN WATERS WITH SEAS BUILDING
UP TO 4 FEET BY THIS EVENING AND TONIGHT. AT THIS TIME...IT APPEARS
THE FRONT WILL STALL BEFORE REACHING THE COAST ON SATURDAY ... THEN
RETREAT NORTH ON SUNDAY. AS A RESULT...WINDS WILL REMAIN WESTERLY
OVER THE COASTAL WATERS TODAY THROUGH SATURDAY. HOWEVER...TIDAL
LAKES MAY EXPERIENCE A NORTHWEST WIND ON SATURDAY WITH FRONT IN THE
AREA. THE FRONT IS EXPECTED TO RETREAT NORTH ON SUNDAY. A WEAK
SURFACE PRESSURE PATTERN WILL BE IN PLACE RESULTING IN WEAK SWRLY
WINDS SUNDAY THROUGH WEDNESDAY. 18
