SHOWERS AND THUNDERSTORMS TAPERING OFF OVER WESTERN ZONES...AS EXPECTED. NEW CONVECTION IS FIRING UP OVER LAKE PONTCHARTRAIN AND SURROUNDING PARISHES ALONG OUTFLOW BOUNDARY DROPPING SOUTHWARD FROM EARLIER CONVECTION. WE WERE ONLY ADVERTISING A SLIGHT 20 PERCENT POP FOR UPPER JEFFERSON... ORLEANS...UPPER PLAQUEMINES AND UPPER ST. BERNARD PARISHES. BUT WITH NEW CONVECTION DEVELOPING AND DROPPING SOUTH...WILL NEED TO BUMP POPS UP TO CHANCE CATEGORY FOR THOSE ZONES FOR THE REMAINDER OF THE EVENING. WILL ALSO RAISE POPS TO SMALL CHANCE CATEGORY FOR THE REMAINDER OF THE EVENING FOR LOWER LAFOURCHE AND LOWER TERREBONNE PARISHES AS WELL...WHERE CONVECTION CONTINUES ALONG COASTAL AREAS. ALL OF THIS NEW...AND LINGERING CONVECTION...WILL MOST LIKELY HAVE ENDED BY AROUND MIDNIGHT...WHEN ONE MORE ZONE UPDATE WILL BE NEEDED TO LOWER/REMOVE ALL OVERNIGHT POPS. AS JUST MENTIONED...SINCE PRECIP STEADILY DECREASING IN COVERAGE OVER WESTERN AND NORTHERN ZONES...WILL ALSO GO AHEAD AND LOWER AND/OR REMOVE POPS FROM THOSE ZONES FOR THE OVERNIGHT. AS BULK OF CLOUDINESS ASSOCIATED WITH THE THUNDERSTORM ACTIVITY SHIFTS SOUTH OUT OVER THE GULF TONIGHT...EXPECT SKIES TO BECOME PARTLY CLOUDY TO MOSTLY CLEAR ACROSS FCST AREA FROM NORTH TO SOUTH THROUGH SUNRISE. ZONE UPDATE WILL BE OUT SHORTLY... /12 ...PREVIOUS DISCUSSION FOLLOWS........................... .DISCUSSION... WE HAVE FAVORED THE NAM AND AWIPS ETA12 PLACEMENT OF THE WEAKENING COLD FRONT NEXT 12-24 HOURS...ESSENTIALLY STALLING IT OUT OVER THE INLAND ZONES NORTH OF LAKE PONCHARTRAIN TOMORROW MORNING AS THE SHORTWAVE ENERGY LIFTS OUT TO THE NORTHEAST. WE WILL CONTINUE WITH CHANCE POPS OVER SOUTH CENTRAL MISSISSIPPI AND AREAS NORTH OF LAKE PONCHARTRAIN AND MAUREPAS EARLY THIS EVENING...THEN WE TAPER THE POPS BACK A BIT OVERNIGHT INTO TOMORROW MORNING. WITH THE UPPER ENERGY MORE LACKING TOMORROW...WE EXPECT LOWER COVERAGES OF SHOWERS AND THUNDERSTORMS ALONG AND SOUTH OF THE STALLED/WEAKENING FRONT. WE WILL GO WITH 20 POPS OR LESS MOST AREAS TOMORROW. THERE WILL BE A FEW CHANGES TO THE COASTAL WINDS ACCOUNTING FOR A MORE INLAND POSITIONING OF THE STALLED FRONT TOMORROW INTO SUNDAY. THE NORTHWESTERLY FLOW OVER THE COASTAL WATERS TONIGHT WILL BE MORE A REFLECTION OF THE RIDGE TO THE SOUTH OVER THE CENTRAL GULFMEX VERSUS ANY RESULT OF A FROPA. WE HAVE NOT MADE ANY SIGNIFICANT CHANGES TO THE REMAINDER OF THE FORECAST THROUGH THE EXTENDED PERIODS. UPPER RIDGE TO THE WEST BUILDS BACK TO THE EAST WITH RISING HEIGHTS AND LOWER MEAN LAYERED HUMIDITY VALUES. IN THE EXTENDED...WE WILL CONTINUE TO GO WITH THE BROAD NOTION OF A TROUGH/LOW WORKING FROM EAST TO WEST ACROSS THE CENTRAL/SOUTHERN GULFMEX THROUGH THE MIDDLE OF NEXT WEEK. WE THEREFORE CONTINUE TO ADVERTISE BRINGING THE WINDS UP A BIT OVER THE OFFSHORE COASTAL WATERS NEXT WEEK. RIDGING ALONG THE GULF COASTAL STATES STILL APPEARS LIKELY TO KEEP ANYTHING OF SIGNIFICANCE SOUTH OF OUR AREA. && .PRELIMINARY POINT TEMPS/POPS...
