What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Aug 15, 2:04 PM EDT, 50 minutes earlier.

Area forecast discussion, Aug 15, 2:04 PM EDT, 50 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
204 PM EDT FRI AUG 15 2014

.SYNOPSIS...
A WEAK FRONT ACROSS THE AREA WILL LIFT NORTH TODAY AND TONIGHT.
ATLANTIC HIGH PRESSURE WILL BE THE DOMINANT FEATURE SATURDAY THROUGH
MUCH OF NEXT WEEK WHILE A WEAK TROUGH PERSISTS INLAND.

&&

.NEAR TERM /THROUGH TONIGHT/...
EARLY THIS AFTERNOON...SHOWERS AND THUNDERSTORMS HAVE STARTED TO
DEVELOP ACROSS INLAND AREAS AND ARE TRACKING EASTWARD WITHIN THE
MEAN FLOW. THE OVERALL THINKING REMAINS THE SAME THAT COVERAGE
WILL STILL BE LIMITED TO SCATTERED AT BEST AND POPS HAVE BEEN
ADJUSTED BASED ON CURRENT AND EXPECTED RADAR TRENDS. SO
FAR...UPDRAFTS HAVE STRUGGLED TO GET TOO TALL LIKELY THANKS TO THE
LESS THAN IMPRESSIVE MID LEVEL ENVIRONMENT. SPC MESOANALYSIS PAGE
SHOWS THAT THE FORECAST AREA IS WITHIN A LARGE AREA OF 1000 J/KG
OF DCAPE DUE TO THE EXPANSIVE MID/UPPER LEVEL DRY AIR. SO...THE
STRONGER STORMS THAT DEVELOP WILL BE CAPABLE OF PRODUCING GUSTY
WINDS. THE OVERALL SEVERE THREAT REMAINS ON THE LOW END BUT WE
CANNOT RULE OUT NEEDING A WARNING OR TWO.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY/...
A ZONAL UPPER LEVEL FLOW WILL PREVAIL WHILE ATLANTIC HIGH PRESSURE
PREVAILS AT THE SURFACE. A LEE TROUGH WILL GRADUALLY DEVELOP SUNDAY
INTO MONDAY...WITH LOW-LEVEL FLOW BECOMING MORE SOUTHWESTERLY. DEEP
WESTERLY FLOW AND THICKNESS ADVECTION WILL ALLOW HIGH TEMPS TO REACH
THE LOWER TO MIDDLE 90S EACH DAY. DRIER LOW-LEVEL AIR AND
CONSIDERABLE MID-LEVEL CAPPING WILL REDUCE PRECIP POTENTIAL SATURDAY
AND SUNDAY. WE ARE ONLY SHOWING A SLIGHT CHANCE OF SHOWERS AND TSTMS
DURING THE AFTERNOON AND EARLY EVENING HOURS...DUE MAINLY TO SEA
BREEZE CONVERGENCE. PWATS RISE ABOVE 1.75" ON MONDAY WHILE THE
INLAND LEE TROUGH STRENGTHENS. CONDITIONS SHOULD BE SOMEWHAT MORE
FAVORABLE FOR DIURNAL CONVECTION ON MONDAY SO WE ARE CARRYING 20-30
POPS.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
A ZONAL FLOW WILL PERSIST MONDAY NIGHT THROUGH WEDNESDAY BEFORE A
BROAD UPPER RIDGE DEVELOPS ACROSS THE EASTERN UNITED STATES LATE
NEXT WEEK. A MOIST AIRMASS WILL BE IN PLACE WITH PWATS GENERALLY
GREATER THAN 1.80". THE AFTERNOON SEA BREEZE AND INLAND LEE TROUGH
WILL BE THE PRIMARY FORCING MECHANISMS FOR DIURNAL CONVECTION.
COVERAGE MAY BEGIN TO DECREASE LATE NEXT WEEK AS THE UPPER RIDGING
CREATES SOME MID-LEVEL CAPPING AND SUBSIDENCE. HIGH TEMPS WILL BE IN
THE LOWER TO MIDDLE 90S EACH DAY.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
THE BIGGEST CONCERN REVOLVES AROUND THE POTENTIAL FOR IMPACTS FROM
SHOWERS AND THUNDERSTORMS THROUGH THIS EVENING. BASED ON THE
CURRENT DEVELOPMENT...KSAV HAS THE HIGHEST LIKELIHOOD AND A VCTS
HAS BEEN ADDED IN THERE THROUGH 22Z. KCHS IS POSITIONED WITHIN
SOME DRIER AIR SO THE THINKING IS THAT THE BULK OF THE ACTIVITY
WILL REMAIN WEST OF THE TERMINAL. STORMS WILL DISSIPATE THIS
EVENING WITH THE LOSS OF HEATING AND VFR CONDITIONS WILL PREVAIL
THROUGH 18Z SATURDAY.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL PREVAIL. VERY LOW
CHANCES FOR FLIGHT RESTRICTIONS IN AFTERNOON/EVENING TSTMS...WITH
THE BEST CHANCE EARLY NEXT WEEK.

&&

.MARINE...
LIGHT AND VARIABLE FLOW THIS MORNING WITH SEAS FAIRLY GLASSY ALONG
THE LAND/SEA INTERFACE GIVEN THE ONGOING TRANQUIL CONDITIONS AND
LACK OF SWELL COMPONENT. LIGHT WINDS SHOULD BECOME MORE SOUTHERLY
LATER TODAY WITH AN OFFSHORE COMPONENT POSSIBLY BY DAYBREAK ON SAT.
SEAS 1 TO 2 FT. CONDITIONS DO NOT LOOK PERFECT FOR WATERSPOUT
DEVELOPMENT ON THE MOISTURE FRONT THIS MORNING...BUT WIND PROFILES ARE
FAVORABLE. WILL HAVE TO SEE WHAT THE DAY/S FIRST VISIBLE SATELLITE
IMAGES SHOW BUT OVERALL POTENTIAL IS LOW END MODERATE AT BEST.

ATLANTIC HIGH PRESSURE WILL BE THE DOMINANT FEATURE SATURDAY THROUGH
WEDNESDAY. SOUTHWESTERLY FLOW WILL BE THE RULE...EXCEPT MORE
SOUTHERLY ALONG THE COAST DURING THE AFTERNOON SEA BREEZE. AN
ENHANCED PRESSURE GRADIENT CAUSED BY A PRONOUNCED LEE TROUGH WILL
SUPPORT DECENT NOCTURNAL SURGES WITH WINDS PEAKING AT 15-20 KT
SUNDAY NIGHT AND MONDAY NIGHT.

&&

.EQUIPMENT...
THE CHARLESTON SC WSR-88D /KCLX/ REMAINS OUT OF SERVICE DUE TO A
SIGNIFICANT MECHANICAL FAILURE. REPAIR WORK CONTINUES TO PROGRESS
WELL AND A RECENT ESTIMATE FOR THE RADAR TO COME BACK INTO
OPERATION IS PERHAPS AS EARLY AS AUGUST 20TH OR 21ST. UNTIL THAT
TIME WE SUGGEST USING THE SURROUNDING RADAR SITES THAT AREA
AVAILABLE AT KJAX...KJGX...KVAX...KLTX AND KCAE.
