AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
942 AM CDT SUN JUN 10 2012
.UPDATE...
MINOR CHANGES MADE TO THE FORECAST. BUMPED RAIN CHANCES TO NEAR
100 WHERE ALL AREAS SHOULD GET SOME COVERAGE. WITH SUCH DENSE
CLOUD COVER AND RAINFALL OVER THE AREA...HIGHS WILL STRUGGLE TO
REACH LOW 80S SO HAVE DROPPED HIGHS TO NEAR THAT.

.PREV DISCUSSION... /ISSUED 914 AM CDT SUN JUN 10 2012/
UPDATE...
..SOUNDING DISCUSSION...
NO PROBLEMS WITH THE FLIGHT THIS MORNING OTHER THAN A BIT OF GUSTY
WIND AT THE TIME OF LAUNCH. QUITE OBVIOUSLY THE SOUNDING IS
EXTREMELY MOIST THROUGHOUT WITH PW VALUES OF 2.2 INCHES. STORMS
THAT DEVELOP WILL CONTINUE TO BE VERY EFFICIENT RAIN PRODUCERS
WITH ONE HOUR RAINFALL RATES NEAR 2 INCHES POSSIBLE. THE STORM
MOTION FROM THE SOUNDING INDICATES STORMS WILL MOVE FAIRLY
WELL...HOWEVER SOME TRAINING OF THE LINES OF STORMS AS THE MOVE IS
ALREADY BEING NOTED. STRONG AND GUSTY WINDS WILL ALSO BE AN ISSUE
THROUGHOUT THE DAY TODAY. WINDS ARE UNIDIRECTIONAL OUT OF THE
SOUTHWEST THROUGH THE ENTIRE SOUNDING WITH THE EXCEPTION OF A MORE
NORTHERLY WIND RIGHT AT THE SURFACE.
98/SO
PREV DISCUSSION... /ISSUED 402 AM CDT SUN JUN 10 2012/
SYNOPSIS...
A WEAK STATIONARY FRONT IS BECOMING VERY DIFFUSE ACROSS SE LA AND
COASTAL MS. AN UPPER LOW IS LOCATED OVER THE LOWER MISSISSIPPI
VALLEY. A SURFACE LOW IS LOCATED OVER EXTREME SW NEBRASKA WITH A
DRY LINE EXTENDING FROM THE LOW SOUTHWARD THROUGH EASTERN COLORADO
AND INTO WEST TEXAS. A COLD FRONT EXTENDS FROM THE LOW
SOUTHWESTWARD INTO SOUTHERN CA.
LOCALLY...TEMPERATURES ARE GENERALLY IN THE LOW TO MID 70S WITH
DEW POINTS IN THE LOWER 70S. SCATTERED SHOWERS AND THUNDERSTORMS
BEGINNING TO SPREAD ACROSS THE AREA AGAIN...WITH THE MAIN AXIS OF
ACTIVITY CURRENTLY LOCATED ROUGHLY ALONG A LINE FROM MORGAN CITY
TO BOGALUSA.
DISCUSSION...
WET CONDITIONS EXPECTED AGAIN TODAY ACROSS MUCH OF THE AREA AS THE
UPPER LOW CONTINUES TO INTERACT WITH THE DISSIPATING STATIONARY
FRONT. CARRYING LIKELY TO DEFINITE POPS ACROSS THE ENTIRE AREA
WITH THE HIGHEST PROBABILITIES ACROSS THE SOUTHEAST HALF OF THE
AREA AND SLIGHTLY LOWER ACROSS THE NORTHWESTERN PORTION OF THE CWA.
00Z SOUNDINGS FROM AROUND THE AREA INDICATE PW VALUES NEAR OR
ABOVE 2 INCHES. THIS WILL RESULT IN SOME STORMS BEING VERY
EFFICIENT RAIN PRODUCERS WITH RAINFALL RATES OF 2 INCHES PER
HOUR COMMON THROUGHOUT THE DAY. A FEW STORMS MAY PRODUCE EVEN
HIGHER RAINFALL RATES OVER SHORT PERIODS OF TIME. THESE HIGH
RAINFALL RATES MAY LEAD TO NUISANCE FLOODING OR PONDING OF WATER
IN LOW LYING AREAS AND IN AREAS OF POOR DRAINAGE. THE AREAL FLOOD
WATCH REMAINS IN EFFECT FOR THE SOUTHEASTERN HALF OF THE
AREA...WHERE LOCALLY HEAVY RAIN WILL ONCE AGAIN BE POSSIBLE TODAY.
THE UPPER LOW IS FORECAST TO BEGIN MOVING AWAY FROM THE AREA ON
MONDAY. THIS WILL RESULT IN A DOWNWARD TREND IN THE POPS ACROSS
THE AREA. UPPER LEVEL WINDS WILL BECOME MORE ZONAL OR SLIGHTLY
NORTHWESTERLY THROUGH THE REMAINDER OF THE PERIOD AS DEEP RIDGING
BUILDS OVER NORTHERN MEXICO AND TEXAS. THIS WILL ALLOW TYPICAL
DIURNALLY FORCED THUNDERSTORMS TO DEVELOP EACH AFTERNOON. WILL
CARRY 20 TO 30 PERCENT POPS EVERY DAY THROUGH THE END OF THE
WEEK.
AS CLOUDS AND CONVECTIVE COVERAGE DECREASE OVER THE NEXT FEW
DAYS...TEMPERATURES WILL ALSO RETURN TO NEAR OR SLIGHTLY ABOVE
NORMAL.
AVIATION...
CONVECTIVE ACTIVITY ON THE INCREASE AGAIN THIS MORNING. THESE
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO BE VERY EFFICIENT RAIN
PRODUCERS DROPPING VISIBILITIES TO LESS THAN 2SM AND DROP CEILINGS
TO AROUND 1500 FT.
MARINE...
STALLED FRONT ALONG THE COASTLINE IS ALLOWING DEEP PLUME OF MOISTURE
AND CONVECTION TO TRACK THROUGH THE COASTAL WATERS AGAIN TODAY.
PERIODS OF MODERATE TO HEAVY RAIN WILL CONTINUE TO IMPACT THE
WATERS TODAY AS AN UPPER LOW MOVES SLOWLY THROUGH THE LOWER
MISSISSIPPI VALLEY. HAZARDOUS WINDS AND SEAS WILL CONTINUE TO
IMPACT THE COASTAL WATERS TODAY AND CAUTION HEADLINES AND SMALL
CRAFT ADVISORIES ARE IN EFFECT FOR PORTIONS OF THE WATERS.
CONDITIONS SHOULD BEGIN TO IMPROVE THIS AFTERNOON. HIGH PRESSURE
WILL BUILD OVER THE NORTHERN GULF DURING THE FIRST PART OF THE
WORK WEEK LEADING TO LIGHTER WINDS AND SEAS THROUGH THE REMAINDER
OF THE PERIOD.
