Area forecast discussion, Mar 10, 4:22 PM CST, 2 hours 50 minutes before
AREA FORECAST DISSCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
422 PM CST THU MAR 10 2016

.SHORT TERM...
AS ADVERTISED A LONG DURATION HEAVY RAINFALL EVENT IS FINALLY
UNDERWAY ACROSS OUR FORECAST AREA. NO MAJOR CHANGES IN THE
THINKING FROM THE LAST FORECAST PACKAGE. HEAVY RAIN IS ONGOING
ACROSS THE FORECAST AREA THIS AFTERNOON MAINLY ALONG AND WEST OF
INTERSTATE 55. BATON ROUGE HAS ALREADY MEASURED THREE INCHES OF
RAIN THIS AFTERNOON. THIS SYSTEM HAS A LOT GOING FOR IT AS IT
SLOWLY MOVES ACROSS THE AREA THROUGH SATURDAY. DEEP MOISTURE WILL
BE IN PLACE...PRECIPITABLE WATER VALUES WILL BE AT A RECORD HIGH
OVER THE NEXT FEW DAYS. THE MEASURED PRECIPITABLE WATER VALUE FROM
THIS MORNING WAS 1.76 INCHES AND THAT WAS A DAILY RECORD...AND I
EXPECT THE NEXT FEW OBSERVATIONS TO BE RECORDS AS WELL. MODELS
INDICATE THAT THE VALUES OVER THE NEXT 24 TO 48 HOURS WILL BE IN
THE 1.8 TO 2.1 INCH RANGE. THAT IS A SIGNIFICANT AMOUNT OF
MOISTURE FOR THIS TIME OF THE YEAR. WARM CLOUD DEPTHS ARE IN THE
12K TO 14K FOOT RANGE...COUPLE THAT WITH THE SLOW MOVING AND
TRAINING NATURE OF THE SHOWERS AND STORMS AND YOU HAVE A RECIPE
FOR FLOODING. THE WEATHER PREDICTION CENTER HAS OUR AREA IN A
MODERATE RISK FOR FLASH FLOODING TONIGHT THROUGH FRIDAY EVENING.
JUST LOOKING AT A FEW TRENDS OF HIGH RES GUIDANCE IT LOOKS AS IF
THIS CURRENT BAND OF RAIN WILL STALL OVER THE NEXT FEW HOURS AND
PIVOT TO MORE OF AN EAST/WEST ORIENTATION BEFORE AN ADDITIONAL BAND
DEVELOPS OVERNIGHT AND MOVES IN BY DAYBREAK. I AM BECOMING MORE
CONCERNED OVERNIGHT WITH THE DEVELOPMENT OF SOME DEEPER CONVECTION
EMBEDDED IN THE OVERALL BAND THAT WOULD GREATLY ENHANCE RAINFALL
TOTALS. THERE IS SOME ELEVATED CAPE THAT WILL BE IN PLACE TONIGHT
AND WITH THESE LITTLE IMPULSES IN THE MAIN FLOW THAT COULD
TRIGGER A FEW STORMS WITH HEAVIER RAIN.

THE SEVERE WEATHER TREAT IS SMALL BUT NON ZERO...WE STILL MAINTAIN
A MARGINAL RISK FOR SEVERE WEATHER TONIGHT WITH DAMAGING WINDS
BEING THE MAIN CONVECTIVE CONCERN OUTSIDE OF HEAVY RAINFALL. AN
ADDITIONAL 3 TO 4 INCHES OF RAIN WITH LOCALLY HIGHER AMOUNTS COULD
IMPACT AREAS WEST OF INTERSTATE 55...BRINGING RAIN TOTALS OT 7 TO
10 INCHES. FOR AREAS EAST OF THE I-55 CORRIDOR IN SOUTHEAST
LOUISIANA AND SOUTHWEST MISSISSIPPI...INCLUDING METRO NEW
ORLEANS...HEAVY RAINFALL OF 3 TO 6 INCHES WITH LOCALLY HIGHER
AMOUNTS OVER 8 INCHES COULD OCCUR TONIGHT AND TOMORROW. AS STATED
IN THE PREVIOUS PACKAGE THERE WAS SHIFT IN THINKING FOR
SATURDAY...AND THAT INDICATION HAS BEEN REINFORCED WITH MODEL
RUNS FOR TODAY. THE HEAVY RAIN THREAT WILL LINGER OVER THE
FORECAST AREA THROUGH SATURDAY AFTERNOON. IT LOOKS LIKE THE
HIGHEST PROBABILITY AREAS FOR HEAVY RAINFALL WILL GENERALLY BE
FROM METRO NEW ORLEANS AND THE NORTHSHORE EASTWARD ACROSS THE
MISSISSIPPI GULF COAST. AN ADDITIONAL 3 TO 5 INCHES OF RAIN WITH
LOCALLY HIGHER AMOUNTS OF OVER 6 INCHES COULD IMPACT METRO NEW
ORLEANS AND NORTHSHORE. THE MISSISSIPPI COAST COULD EASILY SEE 3
TO 5 INCHES OF RAIN AS WELL WITH LOCALLY HIGHER AMOUNTS OVER 6
INCHES POSSIBLE. STORM TOTAL RAINFALL ACROSS THE AREA COULD VARY
FROM 7 TO 10 INCHES FOR THE BATON ROUGE AREA AND MISSISSIPPI GULF
COAST TO A BULLSEYE OF 10 PLUS INCHES FOR METRO NEW ORLEANS AND
THE NORTHSHORE BY THE TIME THE EVENT IS OVER. ALL OF THESE TOTALS
ARE HIGHLY DEPENDENT ON EXACTLY WHERE THE HEAVY RAIN BAND
DEVELOPS...AND IF MULTIPLE AREAS OF HEAVIER RAIN TRAIN OVER THE
SAME LOCATION. SIGNIFICANT FLOODING ISSUES COULD ARISE WITH THIS
EVENT GIVEN THE HIGH RAINFALL TOTALS EXPECTED. 13/MH

.LONG TERM...
THE SYSTEM FINALLY MOVES OUT LATE SATURDAY INTO SUNDAY. ANOTHER
QUICK MOVING IMPULSE WILL MOVE NORTH OF THE AREA. NOT EXPECTING
ANY RAINFALL FROM THAT IMPULSE...SO WE WILL DRY OUT FOR THE
LATTER HALF OF THE WEEKEND. TEMPERATURES WILL WARM INTO THE 80S BY
EARLY NEXT WEEK. THE NEXT CHANCE OF ORGANIZED RAINFALL LOOKS TO
OCCUR IN THE WEDNESDAY THURSDAY TIMEFRAME. A FRONT IS EXPECTED TO
MOVE THROUGH AROUND THAT TIME AND SHOULD BE THE FOCUS FOR
SCATTERED SHOWER AND THUNDERSTORM ACTIVITY. TEMPERATURES WILL
REMAIN MILD...WITH HIGHS IN THE MIDDLE TO UPPER 70S BOTH WEDNESDAY
AND THURSDAY. AS MOISTURE INCREASES OVER THE AREA...OVERNIGHT LOWS
SHOULD CLIMB BACK INTO THE 60S BY WEDNESDAY NIGHT. 13/MH

&&

.AVIATION...
CONDITIONS WILL BE ROUGH THROUGH THE FCST. ALL TERMINALS WILL
LIKELY BE DEALING WITH PERSISTENT MVFR TO IFR CONDITIONS AND COULD
EVEN DROP TO LIFR DURING THE HEAVIER SHRA AND TSRA. WITH THE
EXCEPTION OF THE MS COAST ALL TERMINALS WILL BE DEALING WITH SOME
CONVECTION BY NO LATER THAN 2230Z. WINDS ARE FINALLY RELAXING SOME
SO NOT ANTICIPATING ANY LLWS ISSUES TOMORROW MORNING AROUND MSY
AND NEW. /CAB/

&&

.MARINE...
STRONG ONSHORE FLOW WILL CONTINUE INTO TOMORROW AS THE GRADIENT
RELAXES AND TIGHTENS BACK UP WITH EACH WAVE. SOUTHEAST WINDS WILL
CONTINUE TO RANGE FROM 15 TO 25 KTS AT TIMES. EVEN WHEN THE WINDS
DROP BELOW 20 KTS FREQUENT GUSTS OF GREATER THAN 25 KTS WILL BE
OCCURRING OVER PRETTY MUCH ALL OF THE COASTAL WATERS. SCY FLAGS
WILL REMAIN IN EFFECT THROUGH FRI AND WILL LIKELY NEED TO BE
EXTENDED INTO THE WEEKEND.

THE STRONG ONSHORE FLOW IS ALSO LEADING TO MINOR TO MODERATE COASTAL
FLOODING AND THIS WILL CONTINUE TO BE THE CASE THROUGH TOMORROW AS
WELL. THERE IS A CHANCE THAT TIDES COULD BOUNCE BACK TO 3.5 FT ABV
NORMAL IN ISOLATED AREAS FRI NIGHT AND SAT MORNING WHEN THE WINDS
LOOK TO INCREASE ONCE AGAIN AND THE ASTRONOMICAL TIDE RANGES RAMP
BACK UP. /CAB/
