AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 215 PM EDT THU JUN 17 2010 ...SCATTERED STRONG TO SEVERE STORMS THIS AFTERNOON... ...SOME RELIEF FROM THE HEAT EXPECTED THROUGH EARLY NEXT WEEK... .SHORT TERM...LATEST MSAS ANALYSIS SHOWS LOW PRESSURE DEPARTING THE NEW ENGLAND COAST WITH A TRAILING COLD FRONT OFF THE MID ATLANTIC COAST AND THROUGH THE COASTAL CAROLINAS. MORE OF A SURFACE TROUGH AXIS EXISTS THIS FAR SOUTH AND CURRENTLY STRETCHES THROUGH JESUP AND THE SUWANNEE VALLEY OF FLORIDA. HAVE ACTUALLY SEEN SOME SLIGHTLY DRIER AIR NORTH OF THIS FEATURE WITH DEWPOINTS "ONLY" IN THE LOWER 70S ALONG THE GEORGIA COAST VERSES MID 70S ON PREVIOUS DAYS. THIS WILL ALLOW FOR A SLIGHTLY LATER START TO ROBUST CONVECTION ACROSS THESE AREAS. TO THE SOUTH HOWEVER...MOISTURE REMAINS PLENTIFUL AND ACTIVITY ALONG THE WEST COAST SEABREEZE HAS BEEN PLENTIFUL EARLY TODAY. EXPECT EAST COAST SEABREEZE TO BECOME MORE ACTIVE THROUGH MID AFTERNOON WITH SATELLITE INDICATIONS OF AN INLAND COLLISION APPEARING MORE LIKELY. MAIN FEATURE OF NOTE ALOFT IS THE STRONG 700MB-400MB DIFFERENTIAL VORTICITY BULLSEYE OVER SOUTHEAST GEORGIA. THIS FEATURE IS READILY APPARENT ON VISIBLE IMAGERY AND INITIALIZED WELL BY THE RUC. EXPECT THIS FEATURE TO ENHANCE ACTIVITY ACROSS THE NORTHERN ZONES THIS AFTERNOON WITH SCT STRONG TO SEVERE ACTIVITY LIKELY. MID LEVEL DRY AIR HAS BECOME MORE ENTRENCHED ACROSS THE AREA AND RATHER THAN LIMITING CONVECTION...FEEL THIS WILL ONLY ENHANCE DOWNDRAFT MOMENTUM IN THE STRONGER ACTIVITY THROUGH LATE EVENING. FOR FRIDAY...DRIER AIR WILL CONTINUE TO PUSH IN FROM THE NORTH AND AFFECT MAINLY THE LAYERS ABOVE 700MB. THIS DEGREE OF DRY AIR WILL LIKELY IMPEDE ROBUST CONVECTION OVER THE GA PORTION WITH THE STRONGER ACTIVITY LIMITED TO THE FLORIDA ZONES. STILL...EVEN IN GA...SUFFICIENT MOISTURE IN PLACE IN THE BOUNDARY LAYER ALONG WITH PRESENCE OF LOW LEVEL TROUGH ALL POINTS TO CONTINUED LIKELY POPS FOR THE AFTERNOON AND EVENING. BY SAT...MID LEVEL DRY AIR WILL QUICKLY ERODE AS FRONT WASHES OUT AND RETURN FLOW MOISTENS UP THE COLUMN. STILL SPOKES OF ENERGY EXPECT ON EASTERN SIDE OF RIDGE WHICH WILL ENHANCE ACTIVITY THROUGH THE AFTERNOON HOURS AND ACTIVE EAST AND WEST COAST SEABREEZE ALL POINT TO A DAY OF CONTINUED LIKELY POPS. ONE OF THE AFOREMENTIONED SPOKES OF ENERGY BECOMES A PROMINENT FEATURE FOR SUNDAY AFTERNOON. TIMING OF THIS FEATURE IS STILL IN QUESTION BUT IF CURRENT MODEL TRENDS HOLD THIS WILL PROVE TO BE ANOTHER ACTIVE DAY WITH ENHANCED CHANCES FOR STRONG TO SEVERE STORMS. WILL CAP POPS AT 50 FOR NOW BUT MAY NEED TO BE UPPED TO LIKELY WITH SUBSEQUENT FORECASTS. .LONG TERM...HIGH PRESSURE RIDGE AT THE SURFACE AND ALOFT WILL RE-BUILD TO THE NORTH OF THE REGION AND THIS WILL ALLOW A MORE ONSHORE FLOW TO DEVELOP ALONG WITH LESS ATMOSPHERIC MOISTURE AND THIS WILL DROP POPS BACK DOWN TO CLIMO OR SLIGHTLY BELOW CLIMO LEVELS AT 30-40%. MAX TEMPS WILL ALSO REMAIN NEAR CLIMO VALUES WITH LOWER TO MID 90S INLAND AND UPPER 80S ALONG THE COAST. && .AVIATION...HAVE TEMPO FOR TSRA AT VQQ AND GNV THIS AFTN AND OTHERWISE HAVE VCTS AT REMAINING TERMINALS...AS BULK OF ACTIVITY WILL OCCUR INLAND WITH SBRZ AND OUTFLOW BOUNDARY MERGERS. HAVE KEPT CB AND VCSH FOR SSI TONIGHT WITH POSSIBILITY OF NOCTURNAL STORMS NEAR AREA OF STRONG DIFFERENTIAL VORTICITY MENTIONED IN PARAGRAPH TWO IN SHORT TERM SECTION. && .MARINE...ISOLATED THUNDERSTORMS ARE EXPECTED...BUT WITH LIGHT WINDS THERE WILL BE NO HEADLINES. && .PRELIMINARY POINT TEMPS/POPS...
