AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 341 PM EDT TUE AUG 6 2013 .SYNOPSIS... HIGH PRESSURE WILL BUILD INTO THE REGION FROM THE NORTHEAST MID WEEK...BEFORE SETTLING OVER THE ATLANTIC LATE IN THE WEEK THROUGH THE WEEKEND. A BACKDOOR COLD FRONT COULD POSSIBLY AFFECT THE AREA EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... THE REGION REMAINS SPLIT BETWEEN DRY HIGH PRESSURE TO THE EAST AND DEEPER GULF MOISTURE TO THE WEST. WE HAVE WATCHED AN AREA OF SHOWERS AND ISOLATED TSTMS MOVE THROUGH THE CENTRAL SC MIDLANDS AND THE PEE DEE THIS AFTERNOON. THIS ACTIVITY IS THE REMNANTS OF AN MCS THAT DROPPED OUT OF WESTERN NC EARLIER THIS MORNING. THOUGH SOME OF THIS MAY DROP INTO OUR INLAND SC ZONES LATE THIS AFTERNOON THE DRY AIR IN PLACE WILL LIMIT THE EASTWARD MOTION BEFORE IT DISSIPATES. THE SCATTERED CONVECTION THAT HAS DEVELOPED ACROSS INTERIOR SOUTHEAST GA WILL SLOWLY DISSIPATE THIS EVENING WITH THE LOSS OF HEATING WITH MAINLY DRY CONDITIONS EXPECTED OVERNIGHT. THE LOWER DEWPOINTS ACROSS SOUTHERN SC WILL ALLOW OVERNIGHT TEMPS TO DROP INTO THE UPPER 60S WHILE OTHER AREAS BOTTOM OUT IN THE LOWER 70S. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/... SURFACE HIGH PRESSURE CURRENTLY CENTERED OVER THE NEW ENGLAND STATES WILL CONTINUE TO RIDGE SOUTHWARD ON WEDNESDAY...BEFORE THE AXIS OF HIGH PRESSURE SETTLES OVER THE CENTRAL ATLANTIC THURSDAY AND FRIDAY. THE UPPER LEVEL PATTERN WILL BE DEFINED BY FLAT RIDGING STEADILY STRENGTHENING AS THE WEEK PROGRESSES. EXPECT LIMITED CONVECTIVE COVERAGE AGAIN ON WEDNESDAY WITHIN A SOMEWHAT UNSEASONABLY DRY AIR MASS...AS SEEN IN AFTERNOON DEWPOINTS LINGERING BETWEEN 69 DEGREES TO 71 DEGREES AWAY FROM THE IMMEDIATE COASTLINE. COOLER ONSHORE FLOW WILL LIMIT HEATING...ESPECIALLY CLOSER TO THE COAST WHERE MARINE INFLUENCES WILL BE GREATEST. HIGH TEMPERATURES WILL RANGE FROM THE UPPER 80S TO LOWER 90S...EXCEPT LOW TO MID 80S NEAR THE COAST...A DEGREE OR TWO BELOW SEASONAL NORMALS. WEAK IMPULSES WILL BE ABLE TO SHIFT THROUGH THE BROAD RIDGING...WITH THE MAIN IMPACTS BEING SLIGHTLY HIGHER SKY COVERAGE. LOW TEMPERATURES WEDNESDAY NIGHT WILL ALSO BE COOLER THAN NORMAL...RANGING FROM AROUND 70 TO 72 DEGREES AWAY FROM THE LOCALLY WARMER COASTLINE. A SLIGHT WARMING TREND IS EVIDENT BY THURSDAY AND FRIDAY...AS HEIGHTS ALOFT RISE WITHIN A SUBTLY STRENGTHENING UPPER RIDGE AND A MORE SOLID SOUTHERLY FLOW. AFTERNOON DEWPOINTS WILL ONLY FALL INTO THE LOW TO MID 70S...EVIDENCE OF INCREASING LOW LEVEL MOISTURE SUPPORTING MORE SEASONAL CONVECTIVE DEVELOPMENT. NUMERICAL MODEL SOLUTIONS ARE IN DECENT AGREEMENT THAT A WEAK COASTAL TROUGH WILL INITIATE MORNING SHOWERS/THUNDERSTORMS PUSHING LOCALLY ONSHORE THURSDAY...WITH SCATTERED CONVECTION DEVELOPING ALONG AND INLAND OF THE SEABREEZE DURING THE CLIMATOLOGICALLY FAVORED AFTERNOON/EARLY EVENING HOURS. LESS MORNING COVERAGE IS EXPECTED FRIDAY LACKING THE ENHANCED COASTAL CONVERGENCE FROM THE DIMINISHED TROUGH...YET STILL EXPECT ISOLATED TO SCATTERED COVERAGE ACROSS INLAND AREAS BY THE AFTERNOON HOURS. AS IS TYPICAL WITHIN A SUMMERTIME PATTERN...SHOWER/THUNDERSTORM COVERAGE WILL DECREASE FROM EAST TO WEST THROUGH SUNSET. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... MEDIUM RANGE GUIDANCE IS IN VERY GOOD AGREEMENT THROUGH MOST OF THE LONG TERM PERIOD...LEADING TO A HIGHER THAN NORMAL CONFIDENCE FORECAST. AN EXPANSIVE UPPER LEVEL RIDGE WILL PREVAIL OVER THE REGION THROUGH THE WEEKEND...BEFORE A LONG WAVE TROUGH BEGINS TO EXPAND ACROSS THE EASTERN U.S. EARLY NEXT WEEK. ATLANTIC HIGH PRESSURE AT THE SURFACE WILL PREVAIL THROUGH THE WEEKEND...THEN A BACKDOOR COLD FRONT APPEARS POISED TO DROP TOWARD...IF NOT INTO...THE AREA EARLY NEXT WEEK. CONVECTION WILL BE DIURNALLY DRIVEN THROUGH SUNDAY...WITH ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED ALONG AND AHEAD OF THE SEA BREEZE EACH AFTERNOON AND EARLY EVENING. THE PROBABILITY OF SHOWERS AND THUNDERSTORMS SHOULD INCREASE LATE IN THE WEEKEND BUT MORE LIKELY EARLY NEXT WEEK IN ASSOCIATION WITH THE BACKDOOR COLD FRONT. TEMPERATURES SHOULD BE NEAR NORMAL THROUGH MOST OF THE LONG TERM PERIOD...WITH THE WARMEST TEMPERATURES EXPECTED SUNDAY AND MONDAY AS A DOWNSLOPE FLOW AND COMPRESSIONAL HEATING OCCUR AHEAD OF THE FRONT. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... MAINLY VFR CONDITIONS WILL PREVAIL THROUGH THE 18Z TAF PERIOD... BUT DEEPER MOISTURE ACROSS SE GEORGIA COULD RESULT IN OCCASIONAL REDUCTIONS AT KSAV. THEREFORE...HAVE INCLUDED MVFR TEMPO GROUP WITH SCATTERED SHOWERS NEAR THE TERMINAL. AT KCHS...DRIER AIR WILL GREATLY HINDER SHOWER DEVELOPMENT...THUS WILL EXCLUDE ANY MENTION OF RA IN THE TAF. OVERNIGHT...MODEL SOUNDINGS ONCE AGAIN INDICATE THERE COULD BE LOW CEILINGS...BUT THIS SEEMS MOST LIKELY WEST OF THE TERMINALS. EXTENDED AVIATION OUTLOOK...ISOLATED SHOWERS AND THUNDERSTORMS ARE POSSIBLE EACH AFTERNOON/EARLY EVENING AND COULD RESULT IN BRIEF REDUCTIONS IN CEILINGS/VISIBILITIES. OTHERWISE...VFR CONDITIONS ARE EXPECTED TO PREVAIL. && .MARINE... ONSHORE FLOW WILL PERSIST INTO WEDNESDAY...AS THE MARINE ZONES REMAIN ON THE PERIPHERY OF HIGH PRESSURE BUILDING FROM THE NORTH. THE AXIS OF THE SURFACE HIGH WILL THEN SETTLE OVER THE CENTRAL ATLANTIC BY LATE WEEK INTO THE WEEKEND...SUPPORTING A SOLID SOUTH/SOUTHWEST FLOW. IN GENERAL...WINDS SHOULD REMAIN AT OR BELOW 15 KT... HIGHEST NEAR SEABREEZE CIRCULATIONS ALONG THE COAST. SEAS WILL RANGE BETWEEN 1 TO 3 FT...HIGHEST OVER THE GEORGIA OFFSHORE WATERS. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE.
