AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
1107 AM CDT SUN MAR 27 2016

.UPDATE...
FLASH FLOOD WATCH WAS ISSUED EARLIER FOR AREAS THAT WERE IN LINE
FOR POSSIBLY HIGH RAINFALL RATES OF 2 TO 3 INCHES PER HOUR BASED
ON RADAR TRENDS AND SOME OF THE CONVECTIVE ALLOWING MODELS. SINCE
THAT TIME...RADAR TRENDS ARE NOT NEARLY AS IMPRESSIVE AND THE
LATEST HRRR RUNS ARE ALSO GREATLY DOWNPLAYING THE HEAVY RAINFALL
POTENTIAL. THE SYNOPTIC SCALE ENVIRONMENT...PARTICULARLY THE
COUPLED UPPER JET PATTERN...REMAIN VERY FAVORABLE FOR STRONG
DYNAMIC LIFT FOR AT LEAST A FEW MORE HOURS...SO AM HESITANT TO
DROP THE FLASH FLOOD WATCH AT THIS TIME. REGARDING SEVERE
THUNDERSTORM POTENTIAL...IT STILL APPEARS MARGINAL AT BEST GIVEN
THE PERSISTENT SURFACE TROUGH OFFSHORE THAT IS KEEPING THE MORE
UNSTABLE AIRMASS OVER THE WATER...HOWEVER SOME OF THE
THUNDERSTORMS OVER SOUTHWEST TO SOUTH CENTRAL LOUISIANA DO NOT
HAVE AS MUCH COMPETITION AND COULD GET STRONG ENOUGH FOR BRIEF
STRONGER WIND GUSTS AND MAYBE SOME HAIL...HOWEVER MOST OF THE
INSTABILITY SHOULD REMAIN ELEVATED.

IF CURRENT TRENDS CONTINUE...AND SHOWERS AND THUNDERSTORMS
CONTINUE TO NOT ORGANIZE INTO ANY POTENTIALLY TRAINING BANDS WITH
HIGH REFLECTIVITY...IT IS POSSIBLE THE FLASH FLOOD WATCH COULD BE
CANCELLED EARLY. OVERALL TRENDS OF HIGH RAIN CHANCES DROPPING
DURING THE AFTERNOON AND ENDING BY AROUND SUNSET STILL LOOK
GOOD...BUT LATER UPDATES MAY BE NEEDED. 22/TD

&&

.AVIATION...

FLUCTUATING CONDITIONS FROM IFR TO VFR TO IFR REMAIN PROBLEMATIC
FOR CONFIDENCE IN THE TAF FORECASTS TODAY...SO AMENDMENTS WILL
CONTINUE TO BE ISSUED. LOWER CONDITIONS ARE DUE TO A COMBINATION
OF RESTRICTED VSBYS IN SHRA/FEW TSRA AND SCATTERED LOWER CIGS.
OVERALL CONDITIONS SHOULD BE IMPROVING DURING THE AFTERNOON AND
COVERAGE OF THE SHRA/TSRA DECREASES. PATCHY FOG IS EXPECTED IN
SOME AREAS TONIGHT FROM AROUND 06Z TO 14Z MONDAY
MORNING...DEPENDING QUITE A BIT ON WHETHER CIGS ABOVE 010 CLEAR
OUT AND/OR OTHER CIGS BELOW 010 BUILD DOWN TOWARDS THE GROUND.

.PREV DISCUSSION... /ISSUED 343 AM CDT SUN MAR 27 2016/

SYNOPSIS...L/W TROUGH AXIS CURRENTLY STRETCHES SOUTH FROM
CENTRAL CANADA THROUGH THE NRN PLAINS AND JUST EAST OF THE
ROCKIES. SW FLOW IS ALOFT FROM MEXICO THROUGH THE SERN CONUS AND
MUCH OF THE ATLANTIC COAST. OLD BNDRY DRAPED RIGHT ACROSS THE
COAST WITH THE NEXT COLD FRONT CURRENTLY MOVING THROUGH THE MID MS
VALLEY AND THE SRN PLAINS. HIGH PRESSURE IS PUSHING SOUTH ACROSS
THE HIGH PLAINS AND THE ROCKIES. WIDESPREAD CONVECTION IS ACROSS
SELA AND JUST INTO THE GULF. /CAB/

SHORT TERM...CONVECTION HAS INCREASED IN COVERAGE AND
INTENSITY THROUGH THE NIGHT...ESPECIALLY AFTER 5Z AS LIFT BEGAN TO
INCREASE.

MAIN FOCUS IN THE SHORT TERM IS CONVECTION TODAY. NO MAJOR CHANGES
IN THINKING AS WIDESPREAD SHRA AND TSRA WILL IMPACT MUCH OF THE AREA
THIS MORNING. THE GREATEST IMPACT WILL LIKELY BE ALONG AND EAST OF
THE I-55 CORRIDOR BUT THE ENTIRE AREA WILL SEE A DECENT AMOUNT OF
RAINFALL THROUGH THE MORNING. SHOWERS AND TSRA SHOULD BECOME MORE
WIDESPREAD AS LIFT CONTINUES TO INCREASE THIS MORNING.

AS FOR THE HEAVIEST RAINFALL IT IS THE EASTERN HALF OF THE CWA THAT
WILL SEE MORE INGREDIENTS LINE UP. FIRST WILL BE A STRENGTHENING LL
JET WHICH COULD APPROACH 35-40 KTS AS IT MOVES THROUGH THE SERN HALF
OF THE CWA B/T 12 AND 18Z THIS MORNING. IN ADDITION A MID LVL JET OF
40-55 KTS WILL WORK ACROSS THIS SAME AREA WITH DIFFLUENCE ALOFT.
COMBINE THAT WITH RICH H85 THETA E AIR PUMPING INTO THE SAME REGION
AND PWS OF 1.5-1.75 INCHES SHOULD YIELD SOME EFFICIENT RAIN
PRODUCTION. STORM MOTION WILL GENERALLY BE PARALLEL TO THE STALLED
BNDRY AND THIS COULD LEAD TO TRAINING OF STORMS WITH GREATEST
CONCERN ALONG THE SOUTHSHORE AND COASTAL MS.

AS FOR STRONG/SEVERE...CANT RULE OUT A ROGUE STORM OR TWO ALONG THE
COASTAL AREAS. MAIN CONCERN WOULD BE STRONG TO DAMAGING STRAIGHTLINE
WINDS AND FREQUENT LIGHTNING BUT AS ALWAYS IT DOESNT TAKE MUCH TO
GET A QUICK SPIN UP DOWN HERE. OVERALL NOT MUCH SFC BASED
INSTABILITY TO WORK WITH BUT A GOOD BIT OF ELEVLATED INSTABILITY.
CONCERN IS IF THE BNDRY CAN DRIFT FURTHER NORTH...THEN SOUTH OF THAT
BNDRY STORMS COULD BECOME ROOTED TO THE SFC. AGAIN IF THAT HAPPENS
IT LOOKS LIKE IT WOULD BE CLOSE TO THE COAST.

AS FOR WHEN CONVECTION WILL END...STILL LOOKS LIKE THINGS MAY BEGIN
TO SHUT OFF THIS AFTN IN THE NW AND COULD DO SO QUICKLY. AS
MENTIONED THE LAST FEW DAYS ISENTROPIC DOWNGLIDE COULD BEGIN AROUND
19/20Z IN THE FAR NW WITH DOWNGLIDE OVER THE ENTIRE CWA AROUND 00-
01Z. FRONTAL PASSAGE WILL OCCUR CLOSE TO THE SAME TIME AND ONCE THIS
HAPPENS ALL PRECIP SHOULD SHUT DOWN. THE ENTIRE CWA WILL LIKELY
BE RAIN FREE BY 3Z TONIGHT AND POSSIBLY MUCH SOONER THAN THAT.

MON AND INTO TUE SHOULD BE QUIET WITH COOLER TEMPS AND DRY
CONDITIONS HOWEVER MDLS ARE TRYING TO BRING SOME SHRA BACK INTO THE
REGION LATE TUE AS RETURN FLOW SETS BACK UP AND THE NEXT SYSTEM IS
TAKING SHAPE OUT WEST. /CAB/

LONG TERM...OVERALL THE MEDIUM RANGE MDLS SUGGEST AN ACTIVE PERIOD
FOR THE SECOND HALF OF THE WORK WEEK BUT THEY DO BEGIN TO DIVERGE AS
WE HEAD INTO THE WEEKEND. BOTH THE GFS AND ECMWF DIG AND DEEPEN THE
SYSTEM CURRENTLY ENTERING THE PAC NW TWRDS NV AND UT. THIS AMPLIFIES
THE PATTERN ACROSS THE CONUS PUTTING THE REGION BACK UNDER SW FLOW
AND THUS TAPPING INTO THE SUBTROPICAL JET AND THE PAC MOISTURE. THIS
WILL BRING SHRA AND TSRA BACK INTO THE AREA WED AND THU. PROBLEMS
BEGIN TO SHOW UP WITH FRI AND INTO THE WEEKEND. THE MAIN ISSUE IS
WHAT HAPPENS TO THE BASE OF THE L/W TROUGH. IF IT BREAKS AND CLOSES
OFF FROM THE MAIN L/W WE WILL DRY OUT FRI AND INTO THE WEEKEND AS WE
MOVE UNDER WEAK WNW FLOW AND THE COLD FRONT PUSHES THROUGH. IF THE
BASE DOESNT BREAK OFF AND THE L/W TROUGH REMAINS WEST OF THE AREA
THE FRONT WILL STRUGGLE TO MOVE THROUGH WHILE THE REGION REMAINS
UNDER SW FLOW ALOFT. THIS WOULD LEAD TO BETTER RAIN CHANCES FRI AND
FOR THE START OF THE WEEKEND. THAT ALL SAID OBVIOUSLY CONFIDENCE IS
RATHER LOW FOR THE BACK END OF THE FCST SO WILL USE A BLEND OF THE
MEDIUM RANGE MDLS SHOWING LOW END POPS FRI AND FRI NIGHT AND THEN
DRIER CONDITIONS LATE SAT. THE SAME FOR TEMPS AS WE WILL USE A BLEND
OF THE COLDER GFS AND WARMER ECMWF. /CAB/

AVIATION...CONDITIONS WILL GRADUALLY DEGRADE THROUGH THE EARLY
MORNING HOURS AS WIDE SWATH OF SHOWERS AND THUNDERSTORMS MOVES
ACROSS THE AREA. MVFR CIGS ARE ALREADY DROPPING TO LIFR AT SOME
TERMINAL AND SHOULD SPREAD TO ALL SITES WITHIN THE NEXT FEW HOURS.
PERIODS OF HEAVIER RAIN WILL DROP VISIBILITIES AS WELL. FREQUENT
LIGHTNING WILL ACCOMPANY STRONGER STORMS AND POSSIBLY GUSTY WINDS.
HEAVIER RAIN WILL SHIFT EAST THROUGHOUT THE AFTERNOON AND FOG MAY
BEGIN TO DEVELOP OVERNIGHT. /MEFFER/

MARINE...NUMEROUS THUNDERSTORMS ARE AND WILL CONTINUE TO MOVE
THROUGH THE COASTAL WATERS THIS MORNING. EXPECT THE STRONGEST
CELLS TO PRODUCE WIND GUST IN THE 40 TO 50 KNOT RANGE. ACTIVITY
SHOULD SHIFT EAST LATE MORNING/INTO THE AFTERNOON. CURRENT
ELEVATED SOUTHEAST WINDS WILL SHIFT TO SW AND RELAX THIS AFTERNOON
AS A SURFACE TROUGH APPROACHES FROM THE NORTH. THE FRONTAL
BOUNDARY WILL LIKELY NOT PUSH INTO THE COASTAL WATERS UNTIL MONDAY
JUST BEFORE SUNRISE. THE PRESSURE GRADIENT DOES NOT APPEAR TO BE
VERY TIGHT...SO MAY ONLY BRIEFLY REACH SCS CONDITIONS. WINDS WILL
QUICKLY RELAX BY THE AFTERNOON AS HIGH PRESSURE MOVES CLOSER IN TO
THE AREA. HIGH PRESSURE TO THE NORTH WILL THEN MOVE EAST TUESDAY
INTO WEDNESDAY AS A STRONG LOW PRESSURE SYSTEM DEVELOPS ACROSS THE
PLAINS. THIS WILL CAUSE WINDS TO RISE POSSIBLY TO NEAR SMALL CRAFT
ADVISORY CRITERIA LATE WEDNESDAY INTO THURSDAY. /MEFFER/
