AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NEW ORLEANS LA 255 AM CDT WED AUG 17 2005 .DISCUSSION... UPPER LOW MOVING STEADILY WEST ACROSS THE NORTHERN GULF AND A LITTLE BEHIND SCHEDULE. A NICE AREA OF SUBSIDENCE IS FORMING ON THE NORTH END OF THE UPPER LOW THIS MORNING CAUSING A VORT LOBE TO FORM IN THAT REGION. THIS CAN BE SEEN VERY WELL ON WV IMAGERY. THIS SMALL SHORT WAVE SHOULD HELP IN FORMING A LINE OF SH/TS THIS MORNING. THE LINE SHOULD MARCH WESTWARD AS THE TS ALONG IT MOVE SOUTHWEST. WILL KEEP POPS AT 60% FOR THE AREA BUT WILL HAVE TO WATCH AS THIS VORT LOBE MOVES OVER THE GULF COAST BECAUSE IT MAY HELP PRODUCE TS ON IT LEADING EDGE BUT IT FREQUENTLY DESTROYS CONVECTION AT ITS CENTER. WITH ADDED HEATING OF THE DAY SOME OF THESE TS MAY NEED SOME EXTRA ATTENTION ESPECIALLY ON THE LEADING EDGE OF THE FORMING VORT LOBE. WITH THE UPPER LOW SLIGHTLY BEHING SCHEDULE...IT WILL KEEP POP NUMBERS STAY A LITTLE HIGHER ON THURSDAY. THE UPPER LOW SHOULD MAKE ITS WAY INTO TX BY LATE TOMORROW. ON THE EAST SIDE OF THE LOW A STACKED RIDGE EXISTS AND CONTINUES BUILDING THIS WAY. THIS RIDGE SHOULD CUT PRECIP NUMBERS BACK QUITE A BIT WHILE RAISING TEMPS INTO THE MID AND UPPER 90S BY THE WEEKEND. GFS HAS SHOWN TOTALLY DIFFERENT SOLUTIONS OVER THE PAST FEW DAYS. AND THIS MORNING IS NO EXCEPTION. IT IS STILL NOT INITIALIZING WELL WITH MASS FIELDS OVER THE ATLANTIC WHERE THE RIDGE IS LOCATED BUT TEMPORAL AND SPACIAL RESOLUTION IS QUITE GOOD. EVENTHOUGH THE SOULUTION FROM THE LATEST GFS SHOWS QPF AROUND THE AREA THROUGH THE WEEKEND...WILL SIMPLY NOT SHOW THIS TREND IN THE CURRENT PACKAGE. WE HAVE MENTALLY BOGUSED THE LARGE AREA OF DRY AIR INTO THE GFS SOLUTION AND LET THE MODELS TIMING PLACE THIS AREA OF DRY AIR OVER US STARTING FRIDAY. THIS WILL OFCOURSE DEPEND ON THE UPPER LOW MOVING WEST AND HOW LONG IT TAKES TO DO SO. REALITY CAN BE A LOT DIFFERENT. && .PRELIMINARY POINT TEMPS/POPS...
