AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
1127 AM CDT MON APR 4 2011

.DISCUSSION...OVERALL THINGS ARE GOING ALONG AS EXPECTED. SNDG DID
HAVE A STRONG CAP RIGHT AT H85 AND WE WILL DO AN 18Z SNDG TO SEE HOW
THAT IS DOING. WE HAD A WEIRD FEATURE MOVE IN FROM THE SOUTH OUT OF
THE GULF THAT APPEARED LIKE A GRAVITY WAVE BUT WASNT WHAT YOU WOULD
TYPICALLY CONSIDER A GRAVITY WAVE. IT DID HAVE SUBSIDENCE ON THE
BACK SIDE WHICH HELPED CLEAR OUT SOME OF THE CLOUDS. THE ADDITIONAL
HEATING FROM MORE SUN REACHING THE SFC HAS MADE IT EASIER FOR THE
STRONGER WINDS TO MIX DOWN TO THE SFC AND WITH WINDS BECOMING MORE
UNIDIRECTIONAL WITH TIME WE SHOULD HAVE NO PROBLEM MIXING DOWN QUITE
A BIT OF WIND GUSTS NEAR THE 35 TO 40 MPH RANGE POSSIBLY EVEN
HIGHER. WITH WINDS ALREADY SUSTAINED IN THE 20 TO 25 MPH RANGE IN
ABOUT HALF OF THE CWA AND HIGHER WINDS EXPECTED THIS AFTERNOON WE
HAVE ISSUED A WIND ADV FOR ALL OF THE CWA THROUGH 00Z. AS FOR THE
SVR ASPECT...AS OF YET THINKING IS STILL THE SAME. WE ARE CURRENTLY
GETTING A LOT OF SUN SO WE MAY BECOME MORE UNSTABLE THAN INITIALLY
EXPECTED BUT WE ARE STILL LIKELY GOING TO HAVE TO WAIT ON THE FRONT
AND TROUGH TO GET CONVECTION GOING AND THIS SHOULD BEGIN B/T 17-19Z.
CAP IS STILL AN ISSUE BUT THIS CAP WILL ERODE AS THE DAY WEARS ON SO
EXPECT TO SEE MUCH MORE ACTIVITY ALONG THE FRONT THIS AFTN. CURRENT
TIMING OF CONVECTION/FRONT NEAR BTR AROUND 19Z PUSHING TO I55 AROUND
20-22Z...AND THEN THE SOUTH SHORE AND MS COAST B/T 21-00Z. NPW FOR
THE WIND ADV IS ALREADY OUT AND ZONES AND GRIDS WILL BE OUT SHORTLY.
/CAB/

&&

.SYNOPSIS...
LATEST UPPER AIR ANALYSIS SHOWED THE TROUGH AXIS HUDSON BAY TO
NORTHERN NEW MEXICO. JET ANALYSIS AT 250MB SHOWED A 100 TO 110 KTS
JET STREAK OF 130 KTS FROM TEXAS PANHANDLE TO WISCONSIN AND
ANOTHER JET STREAK ON THE BACK SIDE OF THE TROUGH FROM WEST
MONTANA TO NORTH UTAH. REGIONAL PW PLOTS SHOWED GENERALLY AROUND
AN INCH TO 1.3 FROM EASTERN OKLAHOMA TO TEXAS/LOUISIANA COAST.
SURFACE ANALYSIS SHOWED THE DEEP 988MB LOW OVER LAKE MICHIGAN WITH
THE TRAILING FRONT SOUTHWEST THROUGH SOUTHEAST MISSOURI TO NORTH
CENTRAL TEXAS

&&

.PREV DISCUSSION.../ISSUED AT 343 AM CDT MON APR 4 2011/

SHORT TERM...TODAY AND TONIGHT...
AS THE MAIN WEATHER FEATURE APPROACHES THE FORECAST AREA WITHIN 12
TO 24 HOURS PERIOD...SHORT RANGE MODELS ARE IN AGREEMENT WITH
TIMING. PRESSURE GRADIENT WILL TIGHTENED AS THE SYSTEM MOVES EAST
TODAY. IN ADDITION...PW VALUES WILL INCREASE UP TO 1.7 INCHES
ALONG THE TROUGH AXIS THIS AFTERNOON. LOW LEVEL JET IS EXPECTED
TO DEVELOP FROM TENNESSEE TO SOUTHWEST LOUISIANA WITH THE
STRONGEST WINDS OVER WEST TENNESSEE AND MISSISSIPPI DELTA. GFS
REVEALED BL WINDS INCREASING UP TO 25 KNOTS OVER SOUTHWEST
MISSISSIPPI BY 18Z...STRONGEST FOR THE FORECAST AREA. WIND
ADVISORY HAVE BEEN POSTED NORTH OF THE AREA WITH THESE SOUTH WINDS
AND THINKING 80 TO 90 PERCENT OF BL WINDS WILL LIKELY MIX DOWN TO
THE SURFACE AND YIELD WINDS OF 20 TO 25 MPH WITH UP TO 35 MPH OVER
NORTHWEST ZONES...JUST BELOW WIND ADVISORY. AS THE MAIN TROUGH
MOVES EAST...IT WILL REMAIN POSITIVELY TILTED...KEEPING THE
WAVELENGTH LONG AND THE WINDOW SMALL FOR VEERING WINDS WITH HEIGHT
TODAY. WINDS WILL VEER LESS WITH HEIGHT ALONG THE FRONT. WB ZERO
WAS 10300 FEET AT 00Z AND SHOULD INCREASE TO 12000 FEET WITH
STRONG WAA THIS MORNING THROUGH THIS AFTERNOON. IN ADDITION...5H
TEMP WAS -11C AT 00Z AND SHOULD DECREASE TO -13C. SIGNIFICANT
FORCING WILL BE NEEDED TO PRODUCE HAIL STORMS AND SURFACE HEATING
WILL BE PRESENT FOR STRONG UPWARD VERTICAL MOTION NEEDED FOR HAIL
STORMS. THE MAIN THREAT WILL BE DAMAGING WINDS AS SIGNIFICANT
SPEED SHEAR WILL BE PRESENT THIS AFTERNOON AND EVENING ACROSS THE
FORECAST AREA. STRONG VORT MAX ASSOCIATED WITH THE SYSTEM WILL
SWING ACROSS THE NORTH LOUISIANA AND MISSISSIPPI TONIGHT PRODUCING
A SHARP DECREASE IN THICKNESS LAYERS ACROSS THE FORECAST AREA
AFTER THE FRONTAL PASSAGE. WATER TEMPS ON TIDAL LAKES HAVE CLIMBED INTO
THE MID 70S AND 90 TO 95 PERCENT OF THE BL WINDS BEHIND THE FRONT
WILL MIX DOWN TO THE SURFACE SOUTH OF THESE LAKES. THEREFORE...WILL
MAINTAIN A WIND ADVISORY THIS EVENING. 18

LONG TERM...TUESDAY THROUGH SUNDAY...
TEMPS WILL RESPOND DOWNWARD BELOW NORM TUESDAY AND
WEDNESDAY. THE MAIN TROUGH WILL QUICKLY SHIFT EAST AS A BROAD
RIDGE MOVES OVER THE AREA BY WEDNESDAY. RIDGE WILL CONTINUE TO
SHIFT EAST AS A WEAK TROUGH MOVES ACROSS THE MID MISSISSIPPI
VALLEY THURSDAY INTO FRIDAY. ZONAL FLOW WILL KEEP DEEP MOISTURE
FROM COMING BACK BUT ASSOCIATED DISTURBANCE MAY PRODUCE ISOLATED
CONVECTION ACROSS THE NORTH ZONES LATE THURSDAY INTO FRIDAY.
ANOTHER SYSTEM...SLIGHT STRONGER...WILL BRING A FRONT INTO THE
AREA LATE SUNDAY. 18

&&

.AVIATION...
MAINLY MVFR CEILINGS THIS MORNING WITH THE EXCEPTION OF KGPT WHERE
CLOUD COVER HAS NOT REACHED YET. THIS SHOULD OCCUR IN THE NEXT FEW
HOURS. EXPECT MVFR CONDITIONS TO BE THE PREDOMINANT CONDITION UNTIL
AFTER FRONTAL PASSAGE THIS EVENING. CARRYING CONVECTION IN A 4 HOUR
WINDOW JUST AHEAD OF THE COLD FRONTAL PASSAGE. MAIN ISSUE ASIDE FROM
THE CEILINGS WILL BE WINDS. EXPECT ALL TERMINALS TO BE AFFECTED BY
GUSTS ABOVE 25 KNOTS BY MID DAY...AND SOME GUSTS ABOVE 40 KNOTS
POSSIBLE WITH THUNDERSTORMS. IN ADDITION...WINDS BEHIND THE COLD
FRONT WILL BE IN THE 25 TO 35 KNOT RANGE FOR A TIME IN PROXIMITY TO
LAKE PONTCHARTRAIN AT KMSY AND KNEW. WINDS WILL CONTINUE GUSTY
THROUGH 12Z TUESDAY AT KMSY AND KNEW...BUT SUBSIDE BETWEEN 06Z AND
12Z ELSEWHERE. 35
&&

.MARINE...
WINDS HAVE RESPONDED SLOWER THAN EXPECTED OVERNIGHT...GENERALLY IN
THE 15 KNOT RANGE WHICH IS MORE TYPICAL OF EXERCISE CAUTION
CONDITIONS. THAT BEING SAID...WINDS ARE EXPECTED TO INCREASE OVER
THE NEXT 6 HOURS OR SO TO ADVISORY RANGE...SO WILL LEAVE ADVISORY IN
PLACE. STILL LOOKS BORDERLINE FOR A GALE WARNING AND WILL RIDE WITH
WATCH FOR ONE MORE PACKAGE. WINDS SHOULD RAPIDLY DIMINISH AFTER 18Z
TUESDAY. SEAS MAY GET AS HIGH AS 8 TO 10 FEET OVER THE OUTER WATERS
AFTER FRONTAL PASSAGE...BUT SHOULD QUICKLY SUBSIDE BY TUESDAY
EVENING. 35

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF COASTAL WATERS
OF SOUTHEAST LOUISIANA AND SOUTH MISSISSIPPI...SOUTHEAST
LOUISIANA AND SOUTHERN MISSISSIPPI.

.DAY ONE...TODAY AND TONIGHT
THERE IS A SLIGHT RISK OF SEVERE WEATHER ACROSS THE ENTIRE
OUTLOOK AREA THIS AFTERNOON AND THIS EVENING. ISOLATED TO
SCATTERED THUNDERSTORMS ARE EXPECTED TO AFFECT THE AREA TODAY
AHEAD OF AN APPROACHING COLD FRONT. A FEW OF THESE THUNDERSTORMS
WILL HAVE THE POTENTIAL TO PRODUCE DAMAGING STRAIGHT LINE WINDS.

THE THIS AFTERNOON AND THIS EVENING.

AS THE COLD FRONT MOVES THROUGH THE AREA...IT WILL BE ACCOMPANIED
BY A STRONG SQUALL LINE WITH NUMEROUS THUNDERSTORMS...SOME OF
WHICH WILL BE STRONG TO SEVERE. THE MAIN THREAT FROM THESE
THUNDERSTORMS WILL BE DAMAGING STRAIGHT LINE WINDS...THOUGH LARGE
HAIL AND ISOLATED TORNADOES WILL REMAIN POSSIBLE. THE MOST LIKELY
TIMING FOR SEVERE WEATHER APPEARS TO BE IN THE AFTERNOON AND
EVENING HOURS. THE THREAT OF SEVERE WEATHER SHOULD END BY LATE
EVENING AS THE FRONT MOVES EAST OF THE AREA.

MARINE...
SMALL CRAFT ADVISORY CONDITIONS ARE EXPECTED TO DEVELOP IN
ADVANCE OF THE COLD FRONT BY THIS MORNING THROUGH TONIGHT. IN
ADDITION...A GALE WATCH IS IN EFFECT FOR THIS EVENING THROUGH
TONIGHT FOR STRONG NORTH WINDS AFTER THE FRONTAL PASSAGE.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

MARINE...
SMALL CRAFT ADVISORY CONDITIONS ARE EXPECTED TO CONTINUE EARLY
TUESDAY. OTHERWISE...HAZARDOUS WEATHER IS NOT ANTICIPATED MONDAY
THROUGH SATURDAY.
