The episode as NWS CHS wrote it up.
A few thunderstorms developed over the area as a mid-level shortwave shifted over a moist and warm environment in the southeastern United States.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Charleston, SC wrote its last area forecast discussion before the first event at Aug 18, 4:46 PM EST, 1 hour 32 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 546 PM EDT MON AUG 18 2014 .SYNOPSIS... THROUGH FRIDAY...ATLANTIC HIGH PRESSURE WILL REMAIN SOUTHEAST OF THE REGION AND A TROUGH OF LOW PRESSURE WILL PREVAIL INLAND. A COLD FRONT WILL ADVANCE THROUGH THE AREA THIS WEEKEND...THEN HIGH PRESSURE WILL BUILD FROM THE NORTH INTO EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... EARLY MONDAY EVENING...ADJUSTED POPS BASED ON RECENT/EXPECTED NEAR TERM TRENDS. INTO THIS EVENING...MULTIPLE MESOSCALE BOUNDARIES EMBEDDED WITHIN DEEP LAYER WESTERLY FLOW AND A PERSISTENT LOW-LEVEL POOL OF HIGH THETA-E AIR WILL CONTINUE TO SUPPORT ISOLATED/SCATTERED THUNDERSTORMS WHICH WILL GENERALLY MOVE TOWARD THE EAST AT 15-20 MPH. 850-500 MB WINDS 20-25 KT...MLCAPES 2500-3500 J/KG AND DCAPES EXCEEDING 1000 J/KG SUGGEST THAT MULTICELL THUNDERSTORMS COULD PRODUCE ISOLATED/DAMAGING WIND GUSTS. MAINTAINED A MENTION OF ISOLATED SEVERE THUNDERSTORMS WITHIN THE HAZARDOUS WEATHER OUTLOOK. AFTER DARK...DIURNAL STABILIZATION WILL TRANSLATE TO A GRADUAL DECREASE IN THUNDERSTORMS COVERAGE/INTENSITY. AFTER MIDNIGHT...POPS TAPER TO LESS THAN 15 PERCENT ALL AREAS. CLOUDS LEFT BEHIND BY EVENING CONVECTION SHOULD THIN WITH TIME. LOW TEMPS BY DAYBREAK WILL AVERAGE IN THE MID 70S MOST AREAS... CLOSE TO 80F AT THE COAST AND PERHAPS ISOLATED LOWER 70S WHERE RAIN FALLS FAR INLAND. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/... TUESDAY...THE LARGE SCALE PATTERN SHOWS A SUB-TROPICAL RIDGE ALIGNED EAST-WEST ACROSS THE SW ATLANTIC...FLORIDA AND INTO THE GULF OF MEXICO. WE/RE SITUATED ON THE NORTHERN SIDE OF THIS FEATURE WITHIN A FAIRLY ZONAL FLOW ALOFT. WHILE WE STILL DO HAVE SOME CAP IN PLACE DURING THE MORNING...A FAIRLY WELL PRONOUNCED SHORT WAVE...LOCATED IN THE WESTERN TN VALLEY THIS EVENING WILL ARRIVE DURING THE AFTERNOON. IT/LL TAP INTO CONSIDERABLE PWATS GREATER THAN 2 INCHES AND A MOISTURE PROFILE THAT EXTENDS THROUGH MUCH OF THE TROPOSPHERE. CONVECTION WILL START DEVELOP ALONG THE RESULTANT SEA BREEZE DURING THE EARLY AND MID AFTERNOON AS WE HIT OUR CONVECTIVE TEMPS. BUT ADDITIONAL ACTIVITY WILL TRIGGER JUST UPSTREAM IN RESPONSE TO DIFFERENTIAL HEATING BOUNDARIES AND DUE TO THE PROXIMITY TO THE INLAND SURFACE TROUGH. SOME ORGANIZATION OF STORMS WILL LIKELY OCCUR IN RESPONSE TO THE APPROACHING SHORT WAVE...WITH THE GREATEST COVERAGE TO OCCUR ACROSS OUR CHARLESTON QUAD-COUNTY WHERE 50 POPS HAVE BEEN INTRODUCED. FURTHER SOUTH/SW WE HAVE ALSO SHOWN CHANCE POPS...BUT MAINLY IN THE 30-40 PERCENTILE. THERMODYNAMICS AREN/T OVERLY IMPRESSIVE...BUT EVEN SO MLCAPES 2500-3500 J/KG AND DCAPES AROUND 1000 J/KG SUGGEST A POTENTIAL FOR ISOLATED AND BRIEF WET MICROBURSTS. IT/LL BE ANOTHER HOT AND HUMID DAY WITH 850 TEMPS RISING TO NEAR 19-20C AIDED BY DOWNSLOPE FETCH OFF THE APPALACHIANS WITHIN A DEEP WESTERLY FLOW. BUT ACTUAL MAX TEMPS WILL BE DETERMINED BY THE ONSET OF SHOWERS/T-STORMS AND THE THICKER/WIDESPREAD CLOUD COVER. FOR NOW WE HAVE PLAYED A MORE CONSERVATIVE MID-UPPER 90S...WITH EVEN 90 OR LOWER 90S AT THE COAST PRIOR TO THE SEA BREEZE FORMATION. DEW POINTS WON/T BE ABLE TO MIX OUT MUCH WITH PLENTIFUL MOISTURE...AND WHEN COMBINED WITH THESE TEMPS WILL SUPPORT A MAX HEAT INDEX OF 103-108...OR A LITTLE SHY OF THE HEAT ADVISORY CRITERIA. A FEW COMMUNITIES NEAR THE COAST COULD BRIEFLY HIT A HEAT INDEX OF 110 DEGREES WITH POOLING OF DEW POINTS NEAR THE PASSAGE OF THE SEA BREEZE. BUT THIS WOULD BE A SHORT-LIVED OCCURRENCE AND ENCOMPASS TOO SMALL OF AN AREA TO REQUIRE ANY HEAT ADVISORY. WEDNESDAY THROUGH THURSDAY...THE PATTERN ALOFT WILL AMPLIFY THROUGH THE PERIOD AS A THE MID/UPPER LOW OVER THE GREAT LAKES WEDNESDAY WILL HEAD TOWARD THE MASON-DIXON LINE THURSDAY. SIMULTANEOUSLY THE SUB-TROPICAL ANTICYCLONE OVER THE GULF WILL EXPAND NORTHWARD. RISING MID LEVEL HEIGHTS...850 MB TEMPS CLIMBING ANOTHER DEGREE OR SO AND AN EXPANSION OF THE LOW LEVEL THICKNESS IMPLIES THAT THE HEAT WILL BE CRANKED UP. WITH NVA ACROSS THE REGION WEDNESDAY THERE IS LITTLE CHANCE OF CONVECTION...AND AT BEST ONLY HINTS OF A WEAK SHORT WAVE WITHIN THE NW FLOW THURSDAY. FOR NOW WE/LL GO WITH ONLY SLIGHT CHANCE POPS EACH AFTERNOON/EVENING WITH THE WARM MID LEVELS AND ASSOCIATED SUBSIDENCE CAP...WITH THE OPTION TO INCREASE POPS ON THURSDAY SHOULD A BETTER DEFINED FEATURE INDEED ARRIVE. GIVEN THE LIMITATION OF SHOWERS/T-STORMS WE LOOK FOR TEMPS TO CLIMB ANOTHER DEGREE OR TWO EACH DAY...PERHAPS MAKING A RUN FOR RECORDS AND MAYBE EVEN THE CENTURY MARK IN A COUPLE OF SPOTS /SEE THE CLIMATE SECTION BELOW MORE ADDITIONAL INFORMATION/. THERE WILL BE SOME MIXING OUT OF AFTERNOON DEW POINTS WITH THE DEEP OFFSHORE TRAJECTORIES...BUT WE CERTAINLY COULD BE CLOSE TO OUR HEAT INDEX CRITERIA OF 110 DEGREES BOTH AFTERNOONS...ESPECIALLY THURSDAY. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... THE UPPER RIDGE AXIS TO OUR WEST WILL BECOME MORE AMPLIFIED WHILE A TROUGH CARVES OUT ACROSS THE MID-ATLANTIC REGION. MEDIUM RANGE GUIDANCE IS IN GOOD AGREEMENT THAT A BACKDOOR COLD FRONT WILL DROP TOWARD THE AREA ON FRIDAY...PUSHING THROUGH ON SATURDAY. COMPRESSIONAL HEATING ON FRIDAY AHEAD OF THE FRONT WILL YIELD HIGHS IN THE MID TO UPPER 90S. SOMEWHAT COOLER CANADIAN HIGH PRESSURE BUILDS IN FROM THE NORTH SUNDAY INTO MONDAY WITH INCREASING RAIN CHANCES AS BETTER CONVERGENCE DEVELOPS. && .AVIATION /22Z MONDAY THROUGH SATURDAY/... MAINLY VFR CONDITIONS THROUGH 18Z TUESDAY. THUNDERSTORMS SHOULD DEVELOP IN THE VICINITY OF THE TERMINALS INTO THIS EVENING. WILL AMEND AS DICTATED BY NEAR TERM CONVECTIVE TRENDS. THUNDERSTORMS WILL REDEVELOP TUESDAY...BUT MOST LIKELY NOT BEFORE 18Z. EXTENDED AVIATION OUTLOOK...DECENT SHOT AT FLIGHT RESTRICTIONS IN SCATTERED SHRA/TSRA TUESDAY AFTERNOON/EVENING AS A DISTURBANCE MOVES BY IN THE MID LEVELS OF THE ATMOSPHERE. THEN VFR MUCH OF THE TIME THROUGH FRIDAY...WITH THE NEXT GOOD CHANCE OF SUB-VFR WEATHER TO OCCUR SATURDAY AS A COLD FRONT MOVES IN WITH SCATTERED SHRA/TSRA. && .MARINE... ANY THUNDERSTORMS WHICH EMERGE FROM LAND COULD PRODUCE STRONG WIND GUSTS THROUGH THIS EVENING. OUTSIDE ANY THUNDERSTORMS...THE SEA BREEZE WILL GIVE WAY TO ANOTHER ROUND OF ELEVATED SW WINDS TONIGHT. CAPPED WINDS AT 20 KT...BUT ISOLATED GUSTS AS HIGH AS 25 KT CANNOT BE RULED OUT ESPECIALLY WITHIN AMZ350 AND AMZ374. WINDS WILL THEN VEER TOWARD THE W/SW AND WILL DIMINISH AS THE LAND BREEZE DEVELOPS LATER TONIGHT. SEAS WILL RANGE FROM 2-4 FT WITHIN NEARSHORE WATERS TO AS HIGH AS 4-5 FT BEYOND 20 NM. TUESDAY...WINDS WILL BE SOMEWHAT ELEVATED ACROSS THE MARINE COMMUNITY FOR MID-LATE AUGUST...WITH A SOMEWHAT ENHANCED GRADIENT BETWEEN THE SUB-TROPICAL ATLANTIC RIDGE TO THE SE AND SOUTH AND AN INLAND TROUGH TO THE NW. GIVEN SOME BOOST FROM THE SEA BREEZE CIRCULATIONS SW AND SOUTH WINDS WILL PEAK AS HIGH AS 15-20 KT. SEAS WILL HOLD AT OR BELOW 4 FT. MARINERS ARE ADVISED THAT SOME STRONGER STORMS WILL MOVE OFF THE COAST IN THE LATE AFTERNOON AND EARLY AT NIGHT. SOME OF THESE WILL PRODUCE FREQUENT LIGHTNING STRIKES...HEAVY RAINS AND POSSIBLE WIND GUSTS IN EXCESS OF 30-40 KT. WEDNESDAY THROUGH THURSDAY...THE PATTERN TRENDS TOWARD MORE TRANQUIL CONDITIONS AS THE GRADIENT GRADUALLY RELAXES BETWEEN THE INLAND TROUGH AND THE RIDGING ACROSS FLORIDA. WEST AND SW WINDS WILL HOLD UNDER 10 OR 15 KT AND SEA AT OR BELOW 3 FT. FRIDAY THROUGH SATURDAY...AN UPSTREAM COLD FRONT WILL APPROACH FRIDAY AND LOOKS TO SHIFTS THROUGH ON SATURDAY...AS WINDS CLOCK AROUND TO THE NE. EVEN SO WE DON/T ANTICIPATE THE NEED FOR ANY SMALL CRAFT ADVISORY HEADLINES. && .CLIMATE... RECORD MAX TEMPS... TUE 8/19...
