AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS LA 353 PM CDT MON SEP 3 2007 .DISCUSSION... THE LATEST SURFACE ANALYSIS AND SATELLITE IMAGERY SHOW SURFACE AND MID LEVEL HIGH PRESSURE FIRMLY IN CONTROL ACROSS THE FORECAST AREA. ONLY WIDELY SCATTERED SHOWERS AND THUNDERSTORMS DOT THE RADAR SCOPE...MAINLY IN THE COASTAL AREAS. THE STRONGEST ACTIVITY LIES TO OUR WEST WHERE THE BEST MOISTURE SURGE IS. THE PATTERN REMAINS UNCHANGED OVER THE NEXT 24 HOURS...THUS WE CAN EXPECT ANOTHER ROUND OF DIURNALLY DRIVEN SHOWERS AND THUNDERSTORMS TOMORROW. IT LOOKS LIKE EASTERLY FLOW WILL BRING A BIT OF DRIER AIR TO COASTAL MISSISSIPPI WEDNESDAY THROUGH THE END OF THE WEEK. HOWEVER...THIS SHOULD NOT BE ENOUGH TO PROHIBIT CONVECTIVE DEVELOPMENT GIVEN DAYTIME HEATING AND LOCAL CONVERGENCE. FORTY PERCENT POPS FOR THE DAY...TWENTY PERCENT FOR THE NIGHT LOOKS GOOD FOR THE REMAINDER OF THE WEEK INTO THE WEEKEND. WITH THE CLOUD COVER AND EXPECTED PRECIPITATION ACTIVITY...TEMPERATURES WILL REMAIN AROUND AVERAGE THROUGH THE PERIOD. THE GFS IS HINTING THAT A COLD FRONT WILL APPROACH LATE IN THE WEEKEND. OF COURSE...THIS WOULD HELP TO KEEP RAIN CHANCES UP UNTIL THE PASSAGE EARLY NEXT WEEK. STAY TUNED. && .PRELIMINARY POINT TEMPS/POPS...
