NWS Charleston, SC wrote its last area forecast discussion before the first event at Aug 13, 3:11 PM EST, 2 hours 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 411 PM EDT MON AUG 13 2007 .SYNOPSIS... A WEAK SURFACE TROUGH WILL MOVE ACROSS THE AREA TONIGHT AND TUE. A LEESIDE TROUGH WILL THEN SET UP WED AND MOVE LITTLE THROUGH LATE IN THE WEEK...AS THE ATLC RIDGE REMAINS NEARBY TO THE S AND SE. WE WILL CONTINUE TO HAVE TO KEEP AN EYE ON THE TROPICS EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... WE HAVE SEEN A FEW SHRA AND TSRA IN AND NEAR THE CWFA THIS AFTN...BUT COVERAGE HAS BEEN 10 PERCENT OR LESS. OBVIOUSLY THE STRONG CAP HAS BEEN HOLDING ACROSS MOST OF THE AREA. HOWEVER...WITH INTERACTION OF THE SEA BREEZE BOUNDARY AND A FEW OUTFLOW BOUNDARIES...AIDED BY WEAK SHORT WAVE ALOFT AND APPROACH OF THE SURFACE TROUGH...WE HAVE OPTED TO CARRY ISOLATED CONVECTION THROUGH SUNSET. A FEW LOCATIONS COULD APPROACH THEIR CROSS-OVER TEMPS LATE TONIGHT...PRODUCING A LITTLE FOG ESP IN LOCATIONS THAT WERE FORTUNATE TO RECEIVE A LITTLE RAIN TODAY. THIS IS NOT ENOUGH TO WARRANT INCLUSION IN THE FCST HOWEVER. LOW TEMPS TONIGHT WILL GENERALLY BE IN THE LOWER TO MID 70S...EXCEPT CLOSER TO 80 NEAR THE COAST...AND PERHAPS A FEW CO-OP SITES DROPPING TO NEAR 70 FAR INLAND. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/... THE FCST AREA REMAINS POSITIONED BETWEEN A MID AND UPPER RIDGE TO THE W AND THE TROUGH ALOFT TO OUR E TUE AND TUE NIGHT. SURFACE TROUGH THAT MOVES INTO THE AREA TONIGHT WILL LINGER NEARBY TUE AND TUE NIGHT. ALTHOUGH THERE IS THIS BOUNDARY IN PLACE AND THE SEA BREEZE...THERE IS STILL A STRONG CAP WITH SUBSIDENCE ALOFT...BUT THERE IS NO SHORT WAVE LIKE TODAY. CERTAINLY COULD SEE ISOLATED SHOWERS OR TSTMS GIVEN THAT SREF GUIDANCE DOES HAVE SOME 20 PERCENT PROBABILITIES...BUT MOS GUIDANCE IS CLOSE TO ZERO POPS. WE WILL MAINTAIN THE RAINFREE FCST WITH RAIN PROBABILITIES TOO LOW TO INCLUDE MENTION IN THE PUBLIC FCST. OF CONCERN TUE IS THE POSSIBILITY OF A HEAT ADVISORY. BEST CHANCE FOR ANY HEAT INDICES REACHING 105 OR GREATER IS ALONG THE COASTAL COUNTIES WHERE THERE WILL BE SLIGHT POOLING OF DEWPTS IN THE LOWER TO MID 70S. THIS ALONG WITH MAX TEMPS IN THE MID TO PERHAPS UPPER 90S WILL PRODUCE HEAT INDICES AROUND 105 OR 106 DEGREES. HOWEVER IT DOES LOOK MARGINAL...AND NOT SURE IT WOULD LAST FOR THE REQUIRED TWO HOUR MINIMUM TIME PERIOD. AFTER COORDINATION WITH WFO ILM AND JAX HAVE DECIDED AGAINST A HEAT ADVISORY AT THIS TIME. WILL LET EARLY MORNING FCST STAFF TAKE ANOTHER LOOK TO SEE IF IT IS NECESSARY. FURTHER INLAND THE TEMPS WILL BE CLOSE TO 100 DEGREES IN SOME LOCATIONS...BUT AFTN DEWPTS WILL FALL INTO THE 60S...THUS KEEPING HEAT INDICES BETWEEN 100 AND 105 DEGREES. MIN TEMPS TUE NIGHT WILL BE SIMILAR TO TONIGHT. AGAIN WE WILL APPROACH CROSS-OVER TEMPS IN SOME LOCATIONS SO LIGHT FOG WILL OCCUR. NOT ENOUGH TO INCLUDE IN THE FCST HOWEVER. && .LONG TERM /WEDNESDAY THROUGH MONDAY/... THE REGION WILL REMAIN UNDER THE INFLUENCE OF AN UPPER LEVEL RIDGE THROUGH FRIDAY...WHILE AT THE SURFACE ATLANTIC HIGH PRESSURE AND A PIEDMONT TROUGH WILL DOMINATE. THIS PATTERN WILL LEAD TO A MOIST SOUTHERLY FLOW AT THE SURFACE...WHILE A DOWNSLOPE FLOW AT THE LOW-MID LEVELS OF THE ATMOSPHERE WILL RESULT IN ANOTHER ROUND OF EXCESSIVE HEAT. IN ADDITION TO THE HEAT...HUMID AND HAZY CONDITIONS ARE ALSO EXPECTED. HEAT INDEX VALUES COULD WARRANT THE ISSUANCE OF HEAT ADVISORIES AND/OR PERHAPS EXCESSIVE HEAT WARNINGS WEDNESDAY THROUGH FRIDAY. PRECIPITATION CHANCES LOOK MINIMAL DURING THIS PERIOD...AS SUBSIDENCE AND DRY LOW-MID LEVELS OF THE ATMOSPHERE SHOULD HELP SUPPRESS CONVECTION. CANNOT RULE OUT ISOLATED SHOWERS AND THUNDERSTORMS DURING THE AFTERNOON/EARLY EVENING HOURS HOWEVER. A COLD FRONT SHOULD DROP THROUGH THE AREA FRIDAY NIGHT...BUT MOISTURE REMAINS LIMITED. THIS FRONT WILL USHER IN COOLER...OR A RETURN TO NEAR NORMAL...TEMPERATURES INTO EARLY NEXT WEEK. ISOLATED TO SCATTERED CONVECTION IS POSSIBLE SATURDAY THROUGH MONDAY...ESPECIALLY DURING THE AFTERNOON AND EARLY EVENING HOURS. FORECASTS FROM THE NATIONAL HURRICANE CENTER REGARDING TROPICAL DEPRESSION FOUR SHOULD BE MONITORED. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... CUMULUS IS BUILDING OVER THE AREA AND THERE CONTINUES TO BE ISOLATED CONVECTION NEARBY. THUS HAVE ADDED MENTION OF CB AT BOTH TAF SITES THROUGH THE AFTERNOON. WITH THE SEA BREEZE PUSHING INLAND...THIS WILL COLLIDE WITH A SHORTWAVE AND VARIOUS SMALL BOUNDARIES FROM OTHER CONVECTION. WILL MONITOR THE SITUATION AND AMEND IF/WHEN NECESSARY SHOULD SHRA OR TSRA GET CLOSE ENOUGH TO THE TERMINALS. THERE IS A SMALL POSSIBILITY FOR PATCHY FOG WITH MVFR VSBYS BUT WITH SOME MID LEVEL CLOUDS THAT MAY BE MOVING IN FROM THE NORTHWEST AND THE CROSSOVER TEMPERATURE SEEMS UNLIKELY TO BE REACHED...DID NOT MENTION LOWER THAN VFR AT THIS TIME. EXTENDED AVIATION OUTLOOK...MAINLY VFR CONDS ARE EXPECTED THROUGH SAT...WITH A CHANCE OF SEEING VSBYS OCCASIONALLY DROP TO MVFR LEVELS DURING THE EARLY MRNG HRS IN MIST AND IN ANY AFTN CONVECTION OR HAZE. && .MARINE... SEA BREEZE CAUSING SOME WINDS TO APPROACH 15 KT ALONG THE SC COAST THIS AFTN...CLOSER TO 10 IN GA. AS SYNOPTIC FLOW BECOMES S-SW TONIGHT AHEAD OF THE APPROACHING SURFACE TROUGH AND SHORT WAVE ALOFT...THERE WILL BE A SLIGHT NOCTURNAL SURGE IN WINDS. BUT NOTHING HIGHER THAN 15 KT NOR 3 FOOT SEAS. WINDS WILL THEN VEER TO W AND DECREASE TOWARD DAYBREAK ON TUE. LIGHT OFFSHORE WINDS TUE MORNING WILL BECOME ONSHORE AND INCREASE WITH THE SEA BREEZE AND SYNOPTIC SELY FLOW IN THE AFTN...BUT WILL AGAIN CAP WINDS AND SEAS AT 15 KT AND 3 FT RESPECTIVELY. VEERING WINDS TO THE S-SW TUE NIGHT WITH AGAIN A SMALL SURGE UP TO 15 KT ACROSS MUCH OF THE ATLC WATERS. THIS MAY OCCUR FOR A SLIGHTLY LONGER TIME THAN TONIGHT WITH SMALL BUT STEADY PRES RISES AS ATLC RIDGE STARTS TO WORK ITS WAY BACK TOWARD THE WATERS. AS A RESULT WE MIGHT GET SEAS UP TO AS HIGH AS 4 FT ACROSS THE OUTER GA WATERS. THE COMBINATION OF ATLANTIC HIGH PRESSURE AND A TROUGH OF LOW PRESSURE INLAND WILL RESULT IN S/SW WINDS ACROSS THE COASTAL WATERS WEDNESDAY THROUGH FRIDAY. A RATHER TIGHT SURFACE PRESSURE GRADIENT BETWEEN THESE TWO SYSTEMS AND OCCASIONAL LOW LEVEL JETTING OVER THE COASTAL WATERS COULD RESULT IN RATHER STRONG WINDS AT TIMES. SMALL CRAFT SHOULD EXERCISE CAUTION HEADLINES MAY BE NEEDED IN THE FUTURE...AND SMALL CRAFT ADVISORIES CANNOT BE RULED OUT FOR AT LEAST THE OUTER GEORGIA WATERS LATER THIS WEEK. A COLD FRONT PASSING THROUGH THE AREA FRIDAY NIGHT SHOULD RESULT IN LIGHTER WINDS FOR SATURDAY. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && 33/REV/JAQ
