AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 315 PM EDT SAT JUL 23 2005 .SHORT TERM...RADAR COVERAGE BEGINNING TO SLOWLY INCREASE THIS AFTERNOON WITH FAVORABLE CONDITIONS PRESENT FOR CONTINUED AREAL EXPANSION. RUC ANALYSIS INDICATES A LARGE AREA OF STRONG DIFFERENTIAL VORTICITY ADVECTION OVER EXTREME SOUTHEAST GEORGIA AND NORTHEAST FLORIDA...SLIDING SOUTH. BEST SURFACE CONVERGENCE THUS FAR HAS BEEN WHERE NORTHERLY FLOW ON THE BACK SIDE OF THE TROUGH AXIS IS INTERACTING WITH DEVELOPING WEST COAST SEABREEZE. PRETTY HIGH TRIGGER TEMPS ONCE AGAIN TODAY AND DESPITE THE FACT MOST AREAS ARE VOID OF CONVECTION...GOOD DYNAMICS AND PLENTY OF INSTABILITY THROUGH THE COLUMN WILL EVENTUALLY ALLOW FOR GOOD COVERAGE OF STORMS. WARM COLUMN SHOULD KEEP HAIL THREAT TO A MINIMUM...BUT WINDS COULD BECOME QUITE STRONG WITH INVERTED V SOUNDING INDICATED. MODELS CONTINUE TO ADVANCE FRONTAL BOUNDARY FURTHER SOUTH WITH SUBSEQUENT RUNS AND NORTHEAST FLOW NOW LOOKS TO SET UP OVER THE ENTIRE FORECAST AREA. ACCOMPANYING THE SURGE WILL BE SOME DRIER AIR AT THE SURFACE AND MID LEVELS. GFS LESS AGGRESSIVE WITH THESE FEATURES THAN THE NAM AND CONTINUES LIKELY POPS OVER THE EXTREME SOUTH. FEEL CONVECTION WILL AID NORTHERLY PROPAGATING OUTFLOWS TODAY...PUSHING MAIN MOISTURE AXIS TO A POSITION SIMILAR TO THE NAM. WILL THEREFORE GO WITH LOW END SCATTERED POPS FOR THE SOUTH ON SUNDAY AFTERNOON AND ISOLATED ELSEWHERE. SLIGHT INCREASE IN MOISTURE AT THE SURFACE THROUGH TUESDAY...BUT MID LEVELS SHOULD STAY DRY ENOUGH TO KEEP SLIGHT CHANCE TO LOW END SCATTERED POPS GOING THROUGH MID WEEK. LOOKS AS THOUGH DRIER AIR (LOWER 70S DEWPOINTS VS MID 70S) WILL PREVENT ANY HEAT INDEX VALUES ABOVE 105. THIS IS DESPITE TEMPERATURES IN THE UPPER 90S OVER THE NORTHERN ZONES SO DRY AIR EVOLUTION WILL NEED TO BE MONITORED CLOSELY. .LONG TERM...RIDGE AXIS TO RE-ESTABLISH ITSELF OVER THE AREA BY MID- WEEK WITH INCREASING MOISTURE AND MORE IN THE WAY OF CLIMO POPS. CURRENT GRIDS REFLECT THIS WELL AND LITTLE CHANGE WILL BE MADE. && .MARINE...NORTH TO NORTHEAST WINDS WILL INCREASE BEHIND THE WEAK COLD FRONT MOVING THRU THE AREA TONIGHT. HOWEVER...WINDS AND SEAS WILL REMAIN BELOW CAUTION CRITERIA. SWELLS FROM FRANKLIN ARE EXPECTED TO SLOWLY SUBSIDE SUN...ALTHO THE MOTION AND STRENGTH OF THE SYSTEM WILL AFFECT THIS DECREASE. && .PRELIMINARY POINT TEMPS/POPS...
