NWS Charleston, SC wrote its last area forecast discussion before the first event at Aug 17, 3:01 PM EST, 19 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 401 PM EDT FRI AUG 17 2012 .SYNOPSIS... AN INLAND TROUGH OF LOW PRESSURE WILL PREVAIL THROUGH FRIDAY. A COLD FRONT WILL APPROACH FROM THE NORTH SATURDAY AND STALL ACROSS NORTHERN SOUTH CAROLINA SATURDAY NIGHT INTO SUNDAY. THE FRONT WILL LINGER TO THE NORTH THROUGH EARLY NEXT WEEK BEFORE SHIFTING OFFSHORE. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... SCATTERED SHOWERS AND THUNDERSTORMS NOW MOVING IN FROM THE WEST AND IMPACTING OUR WESTERN COUNTIES. OTHER MORE ISOLATED STORMS FORMING ALONG THE SEA BREEZE...MAINLY OVER CHARLESTON COUNTY. EXPECT SCATTERED CONVECTION TO CONTINUE THROUGH THE AFTERNOON AND EARLY EVENING AS STORMS MOVE GENERALLY FROM WEST TO EAST. THERE IS STILL THE POTENTIAL FOR ISOLATED STRONG TO SEVERE STORMS...BUT LATEST TRENDS SEEM TO BE FAVORING LOWER CHANCES FOR ANY SEVERE STORMS. FOR TONIGHT...MODELS ARE HINTING AT ANOTHER ROUND OF CONVECTION TO FIRE UP LATER TONIGHT WITH ASSOCIATED WITH A SHORT WAVE TROUGH. SEEMS MODELS TYPICALLY OVERDO THESE TYPE OF NOCTURNAL EVENTS DURING THE SUMMER...AND HAVE CONTINUE LOW/SLIGHT CHANCE POP FORECAST FOR NOW. LOW TEMPS WILL BE IN THE LOWER 70S MOST AREAS...EXCEPT MID 70S CLOSER TO THE COAST. THE POTENTIAL FOR PATCHY FOG HAS INCREASED FOR LATER TONIGHT GIVEN THE MORE WIDESPREAD RAINFALL THIS AFTERNOON...BUT CONFIDENCE NOT HIGH ENOUGH TO INCLUDE IN FORECAST AT THIS TIME. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/... SATURDAY...A COLD FRONT WILL SAG SOUTH INTO THE SOUTH CAROLINA MIDLANDS AND PEE DEE SATURDAY AFTERNOON IN RESPONSE TO SHORTWAVE ENERGY DIGGING ACROSS THE EASTERN OHIO VALLEY AND CENTRAL APPALACHIANS. THE EVOLUTION OF CONVECTION IS RATHER UNCERTAIN WITH MODELS SHOWING A POTENTIAL FOR SOME FAIRLY SIGNIFICANT LOWER MID- LEVEL THETA AIR ADVECTING INTO THE REGION AHEAD OF THE FRONT DURING PEAK HEATING. THE LATEST NAM IS THE MOST AGGRESSIVE WITH THE MID-LEVEL DRYING WHILE THE SIGNALS IN THE GFS/ECMWF ARE NOT AS PRONOUNCED. THE EVENTUAL COVERAGE OF SHOWERS/TSTMS WILL BE CLOSELY TIED TO THIS GIVEN THE LACK OF SIGNIFICANT UPPER FORCING. PLAN TO LOWER POPS SLIGHTLY TO 20-40 PERCENT GIVEN THE LATEST MODEL TRENDS WITH THE HIGHEST GRIDDED POPS PLACED ACROSS THE INTERIOR AND FAR NORTHERN ZONES WHICH WILL BE CLOSEST TO THE COLD FRONT ITSELF. CONVERGE MAY BE MORE LIMITED ACROSS SOUTHEAST GEORGIA WHERE CONVECTION WILL BE PRIMARY CLUSTERED ALONG THE SEA BREEZE AND VARIOUS CONVECTIVE OUTFLOWS. MODIFIED SOUNDINGS SHOW MODEST INSTABILITY WILL BE IN PLACE WITH FAIRLY WEAK SHEAR PROFILES. 0-6KM BULK SHEAR IS FORECAST TO INCREASE TO 20-25 KT BY LATE AFTERNOON ACROSS THE CHARLESTON TRI-COUNTY WHICH MAY PROVIDE ENOUGH SUPPORT FOR MORE ORGANIZE MULTI-CELLULAR CLUSTERS...ESPECIALLY IF MESOSCALE BOUNDARY INTERACTIONS OCCUR. THE SPC DAY 2 SEVERE WEATHER OUTLOOK GUIDANCE PRODUCT CURRENTLY HIGHLIGHTS THE NORTHERN PARTS OF THE FORECAST AREA IN A SLIGHT RISK FOR SEVERE TSTMS...BUT CURRENT DATA SUGGEST THE GREATEST RISK FOR ORGANIZED SEVERE WEATHER WILL BE DISPLACED FARTHER TO NORTH AND NORTHEAST WHERE SHEAR PROFILES WILL BE THE STRONGEST. THE RISK FOR ORGANIZED SEVERE WEATHER LOOKS TOO MARGINAL TO INCLUDE A MENTION IN THE HAZARDOUS WEATHER OUTLOOK ATTM. HOPEFULLY...THE NEXT FEW MODELS RUNS WILL YIELD A CLEARER PICTURE ON HOW CONVECTION WILL EVOLVE. SUNDAY...SCATTERED SHOWERS/TSTMS ARE EXPECTED DURING THE AFTERNOON/ EARLY EVENING HOURS AS A RATHER POTENT SOUTHERN STREAM SHORTWAVE CROSSES THE REGION DURING PEAK HEATING. A STATIONARY FRONT TO THE NORTH...LINGERING CONVECTIVE OUTFLOWS FROM TSTMS SATURDAY AS WELL AS THE AFTERNOON SEA BREEZE CIRCULATION WILL THE PRIMARY FOCI FOR CONVECTIVE DEVELOPMENT. SOUNDINGS SHOW MODEST SBCAPE...BUT CONSIDERABLE CLOUD COVER WILL LIMIT OVERALL INSTABILITY SOMEWHAT. 0-6KM BULK SHEAR ON THE ORDER OF 15-20 KT COULD SUPPORT A FEW SEVERE MULTI-CELLULAR CLUSTERS A FEW OF WHICH COULD BECOME SEVERE. AN ORGANIZED SEVERE EVENT IS UNLIKELY ATTM. GRIDDED POPS OF 40-50 PCNT LOOK REASONABLE DURING THIS TIME FRAME...BUT HIGHER POPS MAY EVENTUALLY BE NEEDED. MONDAY...ANOTHER ROUND OF SCATTERED SHOWERS/TSTMS IS EXPECTED AS A PLETHORA OF IMPULSES ROUNDING THE BASE OF THE LONG-WAVE TROUGH TRAVERSE THE REGION AND INTERACTS WITH INCREASING TROPICAL MOISTURE...LIKELY ASSOCIATED WITH THE REMNANTS OF TROPICAL DEPRESSION 7 IN THE BAY OF CAMPECHE. WILL CAP POPS AT 40 PERCENT...BUT HIGHER POPS MAY BE NEEDED AS TEMPORAL AND SPATIAL DETAILS BECOME MORE CERTAIN. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... THE UPPER TROUGH WILL REMAIN ANCHORED ACROSS THE EASTERN HALF OF THE UNITED STATES THROUGH MID WEEK. INITIALLY A STALLED COLD FRONT WILL REMAIN OFFSHORE BEFORE PULLING AWAY FROM THE AREA AROUND WEDNESDAY. THE UPPER TROUGH WILL BEGIN TO WEAKEN THEREAFTER...BUT MODELS STILL SHOW A SERIES OF WEAK DISTURBANCES SWINGING ACROSS THE AREA. OVERALL...EXPECT ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS THROUGH THE EXPENDED PERIOD...ESPECIALLY DURING THE TRADITIONAL AFTERNOON HOURS. SLIGHTLY BELOW NORMAL TEMPERATURES ARE ALSO EXPECTED TO CONTINUE WITH HIGHS IN THE UPPER 80S AND LOWS POSSIBLY DIPPING INTO THE MID TO UPPER 60S. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... CONVECTION HAS KICKED OFF RATHER EARLY AGAIN TODAY. THE BEST CHANCE FOR CONVECTION WILL BE AT KSAV WITH STORMS ALREADY DEVELOPING TO THE SOUTH AND WEST OF THE AREA. HAVE GONE FOR TEMPO STORMS THROUGH THE AFTERNOON...BUT HAVE KEPT VFR CIGS FOR NOW. CHANCES FOR CONVECTION LESS FOR KCHS...BUT THINK THEY WILL HAVE ISOLATED STORMS AROUND THE AREA LATER THIS AFTERNOON WITH THE SEA BREEZE AND OTHER STORMS THAT FORM AND MOVE IN FROM THE WEST. CONVECTION SHOULD DISSIPATE THIS EVENING WITH VFR EXPECTED TO PREVAIL. WILL MONITOR THE POTENTIAL FOR PATCHY FOG LATER TONIGHT...ESPECIALLY IN AREAS THAT RECEIVED RAINFALL. EXTENDED AVIATION OUTLOOK...THERE IS A CHANCE OF SOME LOW CLOUDS AROUND EACH MORNING THROUGH THE WEEKEND...POSSIBLY ENOUGH TO LOWER CIGS TO MVFR FOR AN HOUR OR TWO. OTHERWISE...SCATTERED SHOWERS AND THUNDERSTORMS...MAINLY DURING THE AFTERNOON/EVENING HOURS...COULD RESULT IN TEMPORARY REDUCTIONS IN CIGS/VSBYS THIS WEEKEND. && .MARINE... NO HIGHLIGHTS EXPECTED THROUGH TONIGHT. A TROUGH OF LOW PRESSURE WILL REMAIN INLAND WITH AN ATLANTIC RIDGE CENTERED WELL SOUTHEAST OF THE REGION. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED MAINLY THIS EVENING...BUT ADDITIONAL SHOWERS AND THUNDERSTORMS COULD DEVELOP AGAIN LATER TONIGHT. WINDS ARE EXPECTED TO REMAIN GENERALLY 15 KTS OR LESS AND SEAS 3 FEET OR LESS THROUGH TONIGHT. WINDS MAY BRIEFLY SURGE TO 15-20 KTS LATER TONIGHT OVER THE SC WATERS. HOWEVER...DUE TO A RELATIVELY SHORT DURATION AND UNCERTAINTY IN THE FORECAST FOR THIS SURGE TO OCCUR...HAVE KEPT OUT OF FORECAST FOR NOW. A COLD FRONT WILL APPROACH FROM THE NORTHWEST THROUGH THE WEEKEND...BEFORE STALLING JUST OFF THE SOUTHEAST COAST BY THE MIDDLE OF NEXT WEEK. OVERALL...A SOUTH-SOUTHWEST FLOW IS GENERALLY EXPECTED EACH DAY...WITH THE FLOW VEERING OFFSHORE DURING THE NIGHTTIME/EARLY MORNING HOURS. GENERALLY BRIEF SURGES UPWARDS OF 15-20 KT WILL OCCUR AT TIMES...ESPECIALLY SUNDAY THROUGH MONDAY NIGHT AS THE PRESSURE GRADIENT TIGHTENS IN ASSOCIATION WITH THE APPROACHING COLD FRONT. && .CHS WATCHES/WARNINGS/ADVISORIES...
