AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
318 PM CDT SUN SEP 6 2015

.DISCUSSION...SCATTERED CONVECTION HAS AGAIN DEVELOPED IN A RATHER
HODGEPODGE THIS AFTERNOON. THE THUNDERSTORMS ARE EXPECTED TO ONCE
AGAIN LINGER THROUGH A PORTION OF THE EVENING HOURS BEFORE
DISSIPATING OVER LAND. THE FORECAST AREA IS LOCATED INBETWEEN A
WEAK MID/UPPER LEVEL LOW OVER THE SOUTHEAST CONUS AND AN UPPER
RIDGE CENTERED OVER TEXAS. MODERATELY STRONG NORTHERLY FLOW WAS
NOTED ACROSS THE LOWER MISSISSIPPI VALLEY AND CENTRAL GULF COAST
REGION BETWEEN THESE TWO FEATURES. MODELS FORECAST THE MID/UPPER
LOW TO RETROGRADE ACROSS THE NORTHERN GULF THROUGH THE WORK WEEK
AND GRADUALLY WEAKEN. IT APPEARS THAT SOME DRIER AIR MAY WORK
INTO THE AREA EARLY IN WEEK WHICH WILL LIMIT CONVECTIVE
DEVELOPMENT TO SOME DEGREE...ESPECIALLY ACROSS THE NORTHWESTERN
HALF OF THE FORECAST AREA...BEFORE DEEPER MOISTURE RETURNS FOR THE
MIDDLE AND LATTER PORTIONS OF THE WEEK. AS A RESULT...THE BETTER
RAIN CHANCES ON MONDAY AND TUESDAY WILL BE OVER THE COASTAL AREAS
AND ADJACENT COASTAL WATERS WITH HIGHER RAIN CHANCES SHIFTING
WESTWARD FROM WEDNESDAY ONWARD. IN ADDITION...AN UPPER TROUGH WILL
SWING THROUGH THE UPPER MIDWEST AND GREAT LAKES REGIONS LATE IN
THE WEEK WHICH WILL PUSH A COLD FRONT INTO THE GULF SOUTH
ENHANCING THE CHANCES FOR CONVECTION. THIS COLD FRONT IS EXPECTED
TO BE APPROACHING THE AREA FROM THE NORTH FRIDAY AND MOVE INTO THE
FORECAST AREA FRIDAY NIGHT AND SATURDAY. AT THIS TIME...IT APPEARS
THAT THE FRONT WILL STRUGGLE TO PUSH THROUGH THE FORECAST AREA AND
WILL LIKELY STALL OUT NEAR THE CENTRAL GULF COAST OVER THE
WEEKEND. SOME DRIER AND LESS HUMID AIR STILL SHOULD WORK INTO AT
LEAST THE NORTHERN SECTIONS OF THE FORECAST AREA THOUGH. 11

&&

.AVIATION...
SHOWERS AND THUNDERSTORMS HAVE AGAIN DEVELOPED TODAY AND SHOULD
IMPACT ALL TERMINALS AT SOME POINT THIS AFTERNOON AND EVENING.
EXPECT VFR CONDITIONS OUTSIDE OF THE THUNDERSTORMS THAT COULD YIELD
PERIODS MVFR TO IFR CONDITIONS. THERE HAVE BEEN PLENTY OF LIGHTNING
WITH THE STORMS TODAY. STORMS SHOULD DIMINISH AFTER SUNSET. EXPECT
VFR CONDITIONS TONIGHT BUT THERE IS A CHANCE FOR SOME PATCHY FOG TO
DEVELOP WHERE THE RAINFALL OCCURS THIS AFTERNOON/EVENING. HAVE
INDICATED THAT IN TAFS. EXPECT MORE OF THE SAME CONDITIONS FOR
TOMORROW AS WELL. 13/MH

&&

.MARINE...
NOT MUCH CHANGE IN THE MARINE FORECAST AS AN UPPER LOW SHOULD DEVELOP
OVER THE NORTHERN GULF THROUGH MONDAY AND SLOWLY MOVE WEST THROUGH
THE WEEK. EXPECT GENERALLY LIGHT WINDS THROUGH THE WEEK OVER THE
COASTAL WATERS WITH THE NOCTURNAL JET BRIEFLY KICKING WINDS UP TO
AROUND 10 TO 14 KNOTS OVERNIGHT SEAS SHOULD REMAIN AT 3 FEET OR
LESS THROUGH MID WEEK. SCATTERED THUNDERSTORMS WILL BE POSSIBLE
EACH DAY...MAINLY DURING THE OVERNIGHT AND MORNING HOURS. 13/MH
