NWS Charleston, SC wrote its last area forecast discussion before the first event at Jul 7, 2:51 PM EST, 1 hour 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 351 PM EDT SAT JUL 7 2007 .SYNOPSIS... A WEAK FRONTAL BOUNDARY ACROSS THE INLAND CAROLINAS WILL STALL NW OF THE AREA TONIGHT. HIGH PRESSURE OVER THE ATLANTIC EXTENDING W OVER FL AND INTO THE GULF OF MEXICO WILL ACT TO PREVENT THE FRONT FROM MOVING FURTHER S. THE FRONT WILL LINGER OVER INLAND AREAS BEFORE DISSIPATING MON. HIGH PRESSURE WILL RE-ESTABLISH ITSELF OVER THE AREA DURING THE MIDDLE OF NEXT WEEK...THEN GIVE WAY TO ANOTHER COLD FRONT FOR THE END OF THE WEEK. && .NEAR TERM /THROUGH TONIGHT/... A WEAK FRONTAL BOUNDARY/SURFACE TROUGH NW OF THE AREA WILL REMAIN THERE THROUGH TONIGHT WHILE AN UPPER LOW OVER NRN AL/MS SENDS PIECES OF ENERGY EWD ACROSS SC. MAY SEE A FEW STRONG TO SEVERE STORMS MAINLY THROUGH THE EARLY EVENING HOURS BUT WITH PLENTY OF CLOUD COVER IN PLACE...DO NOT ANTICIPATE A BIG EVENT. WILL MAINTAIN CHANCE POPS ACROSS THE AREA TONIGHT...HIGHEST OVER OUR NW TIER WHICH WILL BE CLOSER TO THE UPPER LEVEL ENERGY AND POSSIBLY THE SLOWLY-MOVING SEA BREEZE. MAY SEE A BIT OF FOG TONIGHT...ESPECIALLY IN AREAS THAT SEE RAIN TODAY AND THEN TRY TO CLEAR OUT LATER TONIGHT. HOWEVER...CONFIDENCE IS TOO LOW IN INTENSITY AND COVERAGE TO MENTION IN THE FORECAST AT THIS TIME. ANOTHER MILD NIGHT CAN BE EXPECTED FOR TONIGHT WITH MOSTLY CLOUDY TO CLOUDY SKIES AND LOWS IN THE MID TO UPPER 70S. && .SHORT TERM /SUNDAY THROUGH SUNDAY NIGHT/... HAVE BUMPED UP POPS TO THE LIKELY RANGE FOR INLAND AREAS SUN AS MORE UPPER-LEVEL SHORTWAVE ENERGY PUSHES ACROSS THE CWFA...INTERACTING WITH A MOIST AND UNSTABLE ATMOS IN PLACE. AGAIN THE POTENTIAL IS THERE FOR STRONG THUNDERSTORMS WITH POSSIBLY ISOLATED SEVERE WEATHER...ESPECIALLY GIVEN CONTINUED HIGH PWATS...MODEST INSTABILITY AND A RELATIVELY STRONG BAND OF MID-LEVEL WINDS. AS THE SHORTWAVE PUSHES FURTHER OFFSHORE SUN NIGHT...AND THE STALLED FRONT INLAND WEAKENS AND BEGINS TO LIFT N...PRECIP CHANCES FALL TO THE 20-30 PERCENT RANGE AFTER MIDNIGHT. ALTHOUGH FORECAST THICKNESSES SUPPORT AT LEAST MID 90S ON SUN...PREFER TO GO AROUND 90 MOST LOCALES WITH A GOOD DEAL OF CLOUD COVER STILL EXPECTED OVER THE AREA. THE WARMEST TEMPS WILL LIKELY BE FOUND ACROSS SE GA WHICH WILL HAVE THE BEST CHANCE OF SEEING MORE SUN. MIN TEMPS SUN NIGHT WILL REMAIN MILD...IN THE MID TO UPPER 70S. && .LONG TERM /MONDAY THROUGH SATURDAY/... EXITING SHORT WAVE TO THE NE MON MORNING WILL BE FOLLOWED BY ANOTHER SHORT WAVE LATE IN THE DAY. AT THE SURFACE...ATLC RIDGE TO REMAIN TO OUR SE WHILE WEAK AREA OF LOW PRES WILL BE FOUND TO THE NW OVER THE SRN APPALACHIANS. MODEST INSTABILITY IS FOUND ACROSS THE AREA BY LATE IN THE DAY AHEAD OF NEXT SHORT WAVE...AND PWATS CONTINUE HIGH AT AROUND 2 INCHES OR MORE. AS A RESULT I WILL CARRY CHANCE POPS ACROSS THE FCST AREA IN THE AFTN...WITH RESULTANT SEA BREEZE TO ALSO HELP FOCUS CONVECTION. ALTHOUGH LAPSE RATES ARE WEAK...THERE IS SOME INCREASE IN VERTICAL WIND FIELDS TO PRODUCE A RISK OF ISOLATED STRONG OR SVR TSTMS. TEMPS WILL BE HELD DOWN A BIT BY CLOUD COVER...BUT STILL LOOKING FOR LOWER-MID 90S MOST AREAS AWAY FROM THE COAST. HEAT INDEX WITH DEWPTS IN THE LOWER-MID 70S LOOK TO REACH ABOUT 100-105 DEGREES...OR JUST BELOW HEAT ADVISORY CRITERIA. BUILDING RIDGE ALOFT BEGINS ACROSS THE AREA TUE AND CONTINUES THROUGH THU OR FRI...BEFORE BREAKING DOWN BY NEXT WEEKEND AHEAD OF A POSSIBLE APPROACHING COOL FRONT TO OUR NW. WITH LOW LEVEL ATLC RIDGE TO OUR SE AND LEESIDE TROUGH DEVELOPING...THIS WILL SHIFT OUR SYNOPTIC FLOW TO A HOTTER WSW DIRECTION AND WILL LIKELY KEEP THE SEA BREEZE PINNED CLOSER TO THE COAST...ESP THROUGH THE MIDDLE PART OF THE WEEK. THIS IN TURN WILL ALLOW FOR HIGHER TEMPS...AND WITH DEWPTS IN THE LOWER-MID 70S WE WILL LIKELY NEED A HEAT ADVISORY FOR AT LEAST A PART OF THE MID AND LATE WEEK PERIOD /HEAT INDICES TUE AND WED LOOK TO BE THE HIGHEST THROUGH THE WEEK/. RAIN CHANCES TUE THROUGH THU WILL BE DIURNALLY DRIVEN...AND WE HAVE GONE WITH NO MORE THAN SLIGHT CHANCE POPS WITH THE ONLY FOCUS THE SEA BREEZE AND ANY BOUNDARIES THAT MOVE IN FROM THE W IN ASSOCIATION WITH THE LEESIDE TROUGH. SLIGHTLY LOWER TEMPS WITH A SMALL INCREASE IN RAIN CHANCES LATE IN THE WEEK AHEAD OF THE FRONTAL BOUNDARY. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... EXTENSIVE MID AND HIGH CLOUDINESS WILL STREAM FROM W TO E ACROSS THE TERMINALS DURING THE NXT 24 HRS IN ASSOCIATION WITH UPPER- LEVEL ENERGY AHEAD OF A TROUGH OVER THE LOWER MS VALLEY. THE MAIN AVIATION CONCERN REMAINS TRYING TO PIN DOWN TIMING AND COVERAGE OF TSTMS THIS AFTN AND EVE. WILL WATCH FOR THE SEA BREEZE TO TRY TO DEVELOP AND PUSH INLAND LATER THIS AFTN AND WITH A MODERATELY UNSTABLE ATMOS IN PLACE...EXPECT SCT SHOWERS AND TSTMS TO DEVELOP. FEEL THAT THE BEST CHANCE OF SEEING TSTMS WILL BE OVER SE GA...THUS THE TEMPO GROUP FOR TSRA AT KSAV. ADDITIONAL TSTM CLUSTERS THAT FIRE ACROSS INTERIOR SE GA AND THE SC MIDLANDS MAY VERY WELL IMPACT BOTH CHS AND SAV AFT DARK GIVEN THE W/NW FLOW ALOFT. SINCE MUCH WL DEPEND ON EVENTUAL MESOSCALE BNDRY INTERACTIONS WITH THE SEA BREEZE WL TAKE A CONSERVATIVE APRCH AND JUST MAINTAIN CB/S AT BOTH SITES THROUGH MID EVNG. WILL CONTINUE TO MONITOR AND AMEND AS NEEDED. COULD SEE SOME LIGHT FOG TONIGHT...ESPECIALLY WHERE RAIN OCCURS AND CLOUDS THIN OVERNIGHT BUT CONFIDENCE NOT HIGH ENOUGH IN THE TIMING AND INTENSITY TO MENTION IN THE 18Z TAFS. EXTENDED AVIATION OUTLOOK...PERHAPS A PERIOD OF MVFR CONDITIONS IN CONVECTION MON...OTHERWISE VFR WX TO PREVAIL. && .MARINE... ATLC HIGH PRES WL REMAIN THE DOMINATE FEATURE ACROSS THE MARINE AREA THROUGH AT LEAST SUN NIGHT. THE GRADIENT WL BEGIN TO PINCH SUN NGT INTO MON WITH THE AREA BECMG CAUGHT BTWN HIGH PRES WELL OFFSHORE AND LWR PRES ACROSS THE SE STATES. A 2-3MB GRADIENT WL LIKELY SUPPORT WNDS OF AT LEAST 15-20 KT...MAINLY ACROSS THE SC WTRS AND GA OFFSHORE WTRS. THIS WL HELP BUILD SEAS INTO THE 3-5 FT RANGE HIGHS ACROSS THE OFFSHORE WTRS. ATTM IT APPEARS CONDITIONS WL REMAIN BELOW SCA THRESHOLDS BUT HEADLINES FOR SMALL CRAFT TO EXERCISE CAUTION MAY EVENTUALLY BE NEEDED. OTRW WNDS WL REMAIN AOB 15 KT WITH SEAS OF 2-3 FT. STILL LOOKS LIKE A PINCHING OF THE PRES GRADIENT WILL AFFECT THE COASTAL WATERS MON...WITH ATLC RIDGE TO THE SE AND WEAK LOW PRES TO THE NW. THIS WILL ALLOW FOR WINDS TO REACH UP TO 15-20 KT AND SEAS TO CLIMB TO 4 OR 5 FT...PERHAPS RESULTING IN SCSEC HEADLINES AT A LATER TIME...EVEN IN CHARLESTON HARBOR WITH ENHANCEMENT FROM THE SEA BREEZE. WITH BUILDING RIDGE ALOFT TUE THROUGH THU AND PRES GRADIENT TO RELAX WILL SEE SWLY WINDS THE REMAINDER OF THE FCST PERIOD...WITH TYPICAL SEA BREEZE AND BACKING OF WINDS TO MORE SLY IN THE AFTN/EVE...THEN VEERING AROUND TO MORE WSW LATE NIGHT/EARLY MORNING. WINDS LOOK TO BE CAPPED AT 15 KT...WITH SEAS GENERALLY 4 FT OR LESS. IT REMAINS TO BE SEEN IF FRONTAL BOUNDARY TO THE NW IS ABLE TO APPROACH BY LATE IN THE WEEK...SO LITTLE CHANGE TO CONDITIONS ARE FCST AT THIS TIME FOR FRI AND SAT. RIP CURRENTS...IF WE ARE ABLE TO SEE ANY SMALL SWELLS REACHING THE BEACHES MON AND/OR TUE WE MIGHT BE LOOKING AT AN ENHANCED RISK OF RIP CURRENTS WITH THE HIGHER WINDS AS A RESULT OF THE SEA BREEZE AND PINCHED GRADIENT. HOWEVER...IT LOOKS TO BE MARGINAL FOR A MODERATE RISK OF RIP CURRENTS EVEN WITH THE SMALL SWELLS...SO NO NEED TO INCLUDE IN THE HWO AT THIS TIME. WILL CONTINUE TO MONITOR. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && RJB/33
