AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS/BATON ROUGE LA 345 PM CDT SAT JUL 19 2003 THE RADAR SCOPE IS LIT UP WITH THUNDERSTORMS...BUT ANY SEVERE WEATHER HAS BEEN VERY ISOLATED THUS FAR. THE BIG FORECAST PROBLEM IS DETERMINING WHERE AND HOW MUCH CONVECTION WILL BE LEFT AT 7 PM FOR THE START OF THE TONIGHT PERIOD. FOR THE REMAINDER OF THIS AFTERNOON...THE LINE OF CONVECTION GENERATED BY THE OUTFLOW BOUNDARY OVER THE NORTHERN CWA/PWA HAS WEAKENED WHILE SEA/LAKE BREEZE CONVECTION HAS INCREASED FROM THE NORTH SHORE OF LAKE PONTCHARTRAIN TO THE MS COAST. CURRENT ACTIVITY OVER THE SOUTHWEST MS AND ADJACENT LA PARISHES SHOULD HAVE EITHER DIMINISHED OR MOVED SOUTH BY 7 PM. WILL MAINTAIN A CHANCE THERE THIS EVENING IN CASE ADDITIONAL ACTIVITY FORMS TO THE NORTH. ISOLATED SEVERE THUNDERSTORMS MAY OCCUR THROUGH SUNSET MAINLY WHERE THE OUTFLOW BOUNDARIES INTERSECT THE SEA BREEZE. FOR SUNDAY...THE GFS APPEARS TO HAVE A PROBLEM WITH CONVECTIVE FEEDBACK AS IT SPINS UP A VORT MAX OUT OF NOWHERE ACROSS THE FORECAST AREA. FOR THIS TO VERIFY...THERE WOULD HAVE TO BE MCS DEVELOPMENT IN NORTHERN MS LATE THIS AFTERNOON OR TONIGHT WHICH WOULD SEND AN MCV INTO OUR AREA ON SUNDAY. THIS CANNOT BE COMPLETELY RULED OUT...BUT FOR NOW WILL MAINTAIN CONTINUITY AND LEAN TOWARDS THE DRIER ETA/NGM SOLUTIONS. SCATTERED THUNDERSTORMS AND A FEW SEVERE STORMS ARE A GOOD BET BY AFTERNOON ON SUNDAY. THE GFS SHOWS A SUBSTANTIAL SHORTWAVE TROUGH ROTATING SOUTHEAST EAST OF THE UPPER HIGH INTO THE AMPLIFYING EASTERN CONUS TROUGH ON MONDAY. MOST OF THE PVA FROM THIS SYSTEM REMAINS EAST OF FORECAST AREA AND DRIER AIR BEGINS TO FILTER IN THE MID LEVELS. WILL MAINTAIN POPS IN THE CHANCE CATEGORY ALTHOUGH THE MODELS LOWER THEM TO SLIGHT CHANCE. THE GFS CONTINUES TO HAVE CONTINUITY...AND IN FACT SPEEDS UP THE COLD FRONTAL PASSAGE TO THE NORTHERN ZONES LATE TUESDAY AND THE COASTAL AREAS ON WEDNESDAY. AFTER COORDINATION WITH ADJOINING WFO/S...WILL CONTINUE TO DELAY THE FRONTAL PASSAGE SOMEWHAT...BUT WILL DECREASE POPS TO SLIGHT CHANCE ACROSS THE NORTHERN HALF OF THE AREA FRIDAY AND SATURDAY. THE MAIN IMPACT OF THE FRONT WILL BE SLIGHTLY LOWER DEWPOINTS AND NIGHTTIME TEMPERATURES NORTH OF LAKE PONTCHARTRAIN AND I-10 THURSDAY THROUGH SATURDAY.
