AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
329 PM CDT MON AUG 16 2010
.SYNOPSIS...
REMNANTS OF TD 5 ARE NOW OFFSHORE SOUTH OF PENSACOLA AND MOVING
WEST. NHC SAYS WEAK CIRCULATION RIGHT NOW...BUT NOT ENOUGH TO
DECLARE A DEPRESSION...PER SPECIAL TROPICAL WEATHER OUTLOOK. MOST
CONVECTION IS AWAY FROM THE CENTER AT THIS TIME ALTHOUGH A RECENT
BLOWUP SOUTH OF MOBILE MAY BE AN INDICATION OF THINGS TRYING TO
FIRE NEAR THE CENTER. MOST OF CWA HAS BEEN IN THE NORTHWEST
SUBSIDENT SIDE OF THE SYSTEM DURING THE DAY AND THIS HAS LIMITED
LAND BASED CONVECTION. COASTAL MISSISSIPPI HAS STARTED SEEING
CONVECTION IN LAST HOUR OR SO...AND EXPECT THIS TO MOVE WESTWARD.
SOME INDICATIONS THAT THERE MAY BE MULTIPLE CIRCULATION CENTERS
BASED ON SURFACE OBS...ALTHOUGH THIS DOES NOT SEEM TO BE REFLECTED
IN SATELLITE LOOPS.
&&
.SHORT TERM...
HAVE OPTED TO MAKE NO SIGNIFICANT CHANGES TO GOING FORECAST. NAM
LOSES SURFACE LOW WITHIN FIRST DAY OF FORECAST. WILL CONTINUE
CURRENT ADVISORIES AS IS. QPF FORECAST FROM EARLIER OF 3 TO 5
INCHES STILL APPEARS REASONABLE WITH LOCALLY HIGHER AMOUNTS.
EXPECT CONVECTION TO REDEVELOP CLOSER TO THE CENTER
OVERNIGHT...ESPECIALLY AS IT NEARS LAND. 35
&&
.LONG TERM...
SOME CLEARING EXPECTED ON THURSDAY NIGHT AS THE REMNANTS OF AN AREA
OF LOW PRESSURE...FORMALLY TROPICAL DEPRESSION FIVE MOVE INTO THE
TENNESSEE RIVER VALLEY AND AN AREA OF HIGH PRESSURE BUILDS OVER THE
GULF OF MEXICO. ON FRIDAY AND SATURDAY...DIURNAL SHOWERS AND
THUNDERSTORMS ARE POSSIBLE SO KEPT CHANCE POPS WITH LESSER CHANCES
IN THE EASTERN PORTIONS OF THE FORECAST AREA. HIGH TEMPERATURES ON
BOTH DAYS WILL REMAIN ABOVE AVERAGE IN THE LOWER 90S WITH HEAT
INDICES IN THE LOWER 100S. SHORTWAVE ENERGY EMBEDDED WITHIN A
LARGE-SCALE UPPER LEVEL RIDGE OVER THE SOUTHERN U.S. MAY BRING A
BETTER OPPORTUNITY FOR SHOWERS AND THUNDERSTORMS FOR SUNDAY ALONG
WITH GUSTY WINDS BOTH ON AND OFF SHORE. A CHANCE OF SHOWERS AND
THUNDERSTORMS WILL CONTINUE INTO EARLY NEXT WEEK WITH HIGH
TEMPERATURES CLOSER TO SEASONAL AVERAGES. MLS
&&
.AVIATION...
CURRENT VFR CONDITIONS SHOULD CONTINUE THROUGH THE EVENING OUTSIDE
OF CONVECTION. EXPECT REDEVELOPMENT OF CONVECTION NEAR COASTAL
SITES BEFORE SUNRISE...WITH MVFR CIGS/VSBYS NEAR CONVECTION.
LOCALLY IFR VSBYS IN HEAVY RAIN. 35
&&
.MARINE...
WILL CONTINUE SMALL CRAFT ADVISORIES AS EARLIER ISSUED. IN
ADDITION...HAVE ISSUED EXERCISE CAUTION FOR LAKE PONTCHARTRAIN FOR
TONIGHT...THEN ADVISORY FOR TOMORROW. WINDS WILL GENERALLY COME
DOWN ON WEDNESDAY AS SYSTEM MOVES AWAY FROM THE AREA. SEAS WILL
GENERALLY INCREASE TO 5 TO 8 FEET OVER NEXT 12-18 HOURS...THEN
GENERALLY COME DOWN ON WEDNESDAY. 35
