AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
443 PM CST FRI MAR 2 2012

.SYNOPSIS...

WATER VAPOR IMAGERY LOOPS SHOW A SPRAWLING AND STRONG UPPER LEVEL
STORM SYSTEM MOVING ACROSS THE MIDWEST AND SOUTHERN ROCKIES WITH A
BELT OF STRONG JET STREAM WINDS FROM NORTHWEST MEXICO ACROSS THE
NORTH GULF COAST STATES. A COLD FRONT EXTENDS SOUTHWEST FROM A
STRONG SURFACE LOW OVER THE OHIO VALLEY INTO NORTHWEST LOUISIANA AND
SOUTHEAST TEXAS. SCATTERED SHOWERS AND A FEW MOSTLY WEAK
THUNDERSTORMS HAVE OCCURRED THIS AFTERNOON ACROSS THE FORECAST
AREA...BUT THERE HAVE BEEN A COUPLE SUPERCELL STORMS...ONE THAT
PROMPTED A TORNADO WARNING EARLIER.

&&

.SHORT TERM...

STRONG SHORTWAVE TROUGH WILL DRIVE SOUTHEAST FROM THE CENTRAL AND
SOUTHERN ROCKIES INTO THE LOWER MISSISSIPPI VALLEY ON SATURDAY
NIGHT. A VERY STRONG BELT OF WINDS FROM 850 MB TO THE UPPER LEVELS
WILL CONTINUE TO INCREASE IN ADVANCE OF THE UPPER TROUGH ACROSS
THE GULF COAST STATES WHICH WILL CREATE STRONG SPEED SHEAR. THE
COLD FRONT WILL MOVE THROUGH MOST OF THE LAND FORECAST AREA
BETWEEN MIDNIGHT AND 6 AM SATURDAY...AND THE REMAINDER OF THE
COASTAL WATERS BY EARLY SATURDAY AFTERNOON. CONDITIONS REMAIN
FAVORABLE FOR STRONG TO SEVERE THUNDERSTORMS TONIGHT...MAINLY
DURING THE LATER EVENING HOURS TO SHORTLY AFTER MIDNIGHT.
SUPERCELL THUNDERSTORMS WITH STRONG DAMAGING WINDS...HAIL...AND
A FEW TORNADOES WILL BE THE INITIAL THREAT...THEN A WEAKENING
SQUALL LINE WILL HAVE A LESSER THREAT OF SEVERE AS THE NIGHT
PROGRESSES. LATE TONIGHT...IT APPEARS THE COLD FRONT WILL SURGE
THROUGH WITH MUCH OF THE PRECIPITATION BECOMING POST-FRONTAL.

DRIER AND COOLER AIR WILL MOVE IN FOR SATURDAY...BUT THERE WILL BE
SOME LINGERING RAIN BEHIND THE FRONT WITH CLOUDY SKIES HOLDING
THROUGH THE DAY. IT WILL BECOME BREEZY...ESPECIALLY DOWNWIND FROM
THE TIDAL LAKES AND NEAR THE COAST SATURDAY AFTERNOON AND EVENING.

HIGH PRESSURE AT THE SURFACE AND NORTHWEST FLOW ALOFT WILL BRING
CLEAR SKIES AND VERY COOL TEMPERATURES SATURDAY NIGHT AND SUNNY
SKIES...MILD TEMPERATURES...AND VERY LOW HUMIDITY ON SUNDAY.

.LONG TERM...

A QUIETER WEATHER PATTERN WILL PREVAIL...AND THERE IS CONSIDERABLE
MODEL SPREAD AS THE WEEK PROGRESSES. THE GFS BRINGS A COLD FRONT
INTO THE AREA IN THE WEDNESDAY TO THURSDAY TIME FRAME WHILE THE
ECMWF IS SLOWER BRINGING A WEAK COLD FRONT IN ON FRIDAY. AT THIS
TIME...HAVE NOT GONE HIGHER THAN A SLIGHT CHANCE OF RAIN DURING
THE WEDNESDAY TO FRIDAY PERIODS. 22/TD

&&

.MARINE...

COLD FRONT WILL MOVE THROUGH MARINE AREA LATE TONIGHT AND
SATURDAY. STRONG NORTH WINDS 20 TO 25 KNOTS WILL DEVELOP OVER MOST
WATERS SATURDAY AFTERNOON AND INCREASE TO 25 TO 30 KNOTS OVER
PORTIONS OF THE WATERS SATURDAY NIGHT BEFORE DIMINISHING BELOW 20
KNOTS BY LATE SUNDAY MORNING. HIGH PRESSURE WILL BRING ONE CALMER
DAY ON MONDAY BEFORE A TIGHTER PRESSURE GRADIENT BRINGS STRONGER
SOUTHEAST WINDS BACK ON TUESDAY. 22/TD

.AVIATION...

VFR CONDITIONS SHOULD PREVAIL AT MOST TERMINALS THROUGH THE
AFTERNOON. HOWEVER...A FEW PLACES MAY STILL SEE PERIODS OF CIGS
AROUND 2500 FT. EXPECT BREEZY CONDITIONS TO PERSIST THIS AFTERNOON
DUE TO A TIGHT PRESSURE GRADIENT WITH SUSTAINED WINDS IN THE 15 TO
20 KT RANGE AND FREQUENT GUSTS AROUND 25 KT. DURING THE LATE EVENING
AND OVERNIGHT HOURS...A STRONG COLD FRONT WILL AFFECT THE TERMINALS.
HAVE ATTEMPTED TO TIME THE CONVECTION USING TEMPO GROUPS...BUT THE
TIMING WILL CONTINUE TO BE REFINED WITH FUTURE ISSUANCES AND
EVENTUALLY AMENDMENTS IF NECESSARY. FRONT SHOULD BE THROUGH ALL OF
THE TERMINALS BY ABOUT 15Z WITH A WIND SHIFT TO THE NORTH OR
NORTHWEST AND LOW CIGS LIFTING SLOWLY THROUGH THE MORNING.

LOUISIANA...SOUTH MISSISSIPPI AND THE ADJACENT COASTAL WATERS.

.DAY ONE...TODAY AND TONIGHT

THERE IS A SLIGHT RISK OF SEVERE WEATHER TODAY...MAINLY ALONG AND
NORTH OF THE INTERSTATE 10 AND 12 CORRIDOR. THE MAIN CONCERNS WILL
BE DAMAGING WINDS AND LARGE HAIL ALTHOUGH AN ISOLATED TORNADO OR
TWO CANNOT BE RULED OUT. THE MAIN TIME FRAME WILL BE THIS

SEVERE WEATHER.

AHEAD OF THE COLD FRONT...A TIGHT PRESSURE GRADIENT WILL RESULT
IN STRONG WINDS ACROSS THE AREA TODAY. SUSTAINED WINDS OF 15 TO
20 MPH WITH FREQUENT GUSTS OF 25 TO 30 MPH MAY CAUSE HAZARDOUS
DRIVING CONDITIONS ON SOME ELEVATED ROADWAYS AND
BRIDGES...ESPECIALLY THOSE THAT ARE ORIENTED EAST TO WEST.

SMALL CRAFT EXERCISE CAUTION HEADLINES HAVE BEEN POSTED OVER ALL
OF THE COASTAL WATERS DUE TO SUSTAINED WINDS OF 15 TO 20 KNOTS. A
SMALL CRAFT ADVISORY MAY STILL BE NEEDED IF WINDS BECOME A TAD
STRONGER THAN EXPECTED.

PLEASE REFER TO THE LATEST RIVER FLOOD STATEMENTS FOR ADDITIONAL
DETAILS.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

ISOLATED TO SCATTERED THUNDERSTORMS WILL STILL BE POSSIBLE
SATURDAY MORNING ALONG AND AHEAD OF THE COLD FRONT WHICH SHOULD
QUICKLY BE ENTERING THE GULF. A FEW OF THESE STORMS COULD STILL
BE STRONG WITH MAINLY GUSTY WINDS...FREQUENT CLOUD TO GROUND
LIGHTNING...AND EVEN WATERSPOUTS ACROSS THE COASTAL WATERS.

SMALL CRAFT EXERCISE CAUTION HEADLINES OR SMALL CRAFT ADVISORIES
WILL BE NECESSARY TOMORROW THROUGH SUNDAY AFTERNOON BEHIND THE
COLD FRONT.
