AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
331 PM CDT TUE JUL 8 2014
.DISCUSSION...
AN UPPER LEVEL TROUGH IS IN THE PROCESS OF DIGGING SOUTHWARD ACROSS
THE GREAT LAKES AND OHIO RIVER VALLEY TODAY AND WILL CONTINUE TO
PROTRUDE FURTHER SOUTH AS IT PROGRESSES EAST. AT THE SAME TIME...
MOISTURE HAS BEEN BACK ON THE INCREASE IN THE MID AND UPPER LEVELS.
THIS MORNING/S AT LIX SHOWED A PRECIP WATER VALUE OF NEAR 1.5 INCHES
AND MODEL SOUNDINGS INDICATE THAT THIS VALUE COULD BE NEAR 2 INCHES
BY THE 00Z FLIGHT. SO ITS NO SURPRISE THAT QUITE A BIT OF CONVECTION
HAS DEVELOPED TODAY. THE HRRR HAS DONE A PRETTY DECENT JOB OF
INITIALIZING AND KEEPING UP WITH THE CURRENT RADAR TRENDS. ITS
DEPICTION OF DIMINISHING ACTIVITY BY SUNSET AGREES WELL WITH TYPICAL
EXPECTATIONS OF STORM DISSIPATION WITH LOSS OF DAYTIME HEATING.
A WEAK COLD FRONT ASSOCIATED WITH THIS UPPER LEVEL TROUGH WILL
GRADUALLY SAG CLOSER AND CLOSER TO THE AREA AS WE APPROACH THE
WEEKEND. IT APPEARS THAT THE BOUNDARY WILL EVENTUALLY REACH THE
CWA BUT WILL BE IN A NEARLY INDISCERNIBLE STATE. LOCAL WEATHER
CONDITIONS FROM TODAY THROUGH THE WEEKEND WILL NOT BE VERY DIFFERENT
FROM DAY TO DAY. DAYTIME POPS SHOULD GENERALLY BE AROUND 30-50
PERCENT WITH A PEAK OF 60 PERCENT ON THURSDAY. NOCTURNAL OFFSHORE
SHOWERS POSSIBLE AS WELL. TEMPERATURES THROUGH THIS PERIOD WILL BE
NEAR NORMAL.

.AVIATION...
MOISTURE RETURN HAS TRIGGERED SCATTERED CONVECTION THAT CONTINUES TO
DEVELOP THIS AFTERNOON. WHILE MOST TERMINALS ARE VFR...CONVECTION
WILL PRODUCE BRIEF IFR CONDITIONS AS THEY AFFECT TERMINALS. CARRYING
VCTS WITH TEMPO IFR AS APPROPRIATE OVER THE NEXT 3-4 HOURS.
CONVECTION SHOULD DIMINISH AS WE APPROACH SUNSET. VFR CONDITIONS
WILL BE THE RULE OVERNIGHT...WITH CONVECTIVE DEVELOPMENT AGAIN
ANTICIPATED ON WEDNESDAY BY LATE MORNING TO EARLY AFTERNOON. 35
&&
.MARINE...
A BRIEF NOCTURNAL MAX OF 10 TO 15 KNOTS IN THE NEARSHORE WATERS OF
LA AND MS ARE EXPECTED TONIGHT AND TOMORROW NIGHT AS A WEAK SURFACE
TROUGH TO THE NORTH TIGHTENS THE PRESSURE GRADIENT. OTHERWISE...
RELATIVELY LIGHT WIND AND WAVE CONDITIONS ARE EXPECTED TO PREVAIL
THROUGH MOST OF THE UPCOMING WEEK DUE TO A RIDGE OF HIGH PRESSURE
OVER THE REGION. SCATTERED CONVECTION WILL CONTINUE TO BE A THREAT
THROUGH THE FORECAST PERIOD. 35
