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 Jul 17, 4:17 PM EDT, 22 minutes earlier.

Area forecast discussion, Jul 17, 4:17 PM EDT, 22 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
417 PM EDT TUE JUL 17 2012

.SYNOPSIS...
ATLANTIC HIGH PRESSURE WILL EXTEND ACROSS THE REGION THROUGH LATE
WEEK....WHILE A WEAK TROUGH LINGERS INLAND. A COLD FRONT WILL
STALL NEAR THE FORECAST AREA THIS WEEKEND...LEADING TO UNSETTLED
CONDITIONS BEFORE DISSIPATING EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
A MORE CAPPED ATMOSPHERE TODAY RESULTED IN A LATER START TO THE
CUMULUS FIELD IN MOST AREAS AND SW LOW-LEVEL FLOW HAS DELAYED THE
INLAND SEABREEZE PENETRATION. THUS OUR INITIAL CONVECTION TODAY
WAS INLAND GA IN A REGION OF BETTER UPWARD VERTICAL VELOCITY
ASSOCIATED WITH THE UPPER LOW AND INLAND LEE TROUGH. A VERY WEAK
STEERING FLOW HAS RESULTED IN ERRATIC CELL MOTIONS WITH A LOT OF
MERGING...AND A RATHER UNUSUAL EAST OR SOUTHEAST MOTION. THE
SEABREEZE HAS FINALLY BEGUN TO LIGHT UP BUT MANY AREAS HAVE BEEN
SOMEWHAT STABILIZED BY CONVECTIVE OUTFLOWS. ISOLATED TO SCATTERED
CONVECTION SHOULD CONTINUE UNTIL EARLY THIS EVENING BEFORE
BEGINNING TO DISSIPATE. OVERNIGHT THE BEST MOISTURE CONVERGENCE
WILL SHIFT TO THE COASTAL WATERS.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
THE UPPER LEVEL PATTERN WILL CONSIST OF A BROAD TROUGH OVER THE
ENTIRE EAST COAST...WHILE AN ATLANTIC RIDGE STEADILY STRETCHES
TOWARD THE SOUTHEAST STATES BY LATE IN THE WEEK. THE SURFACE PATTERN
WILL MIRROR THIS SCENARIO...WITH ATLANTIC HIGH PRESSURE AND A WEAK
INLAND TROUGH PERSISTING THROUGH THE SHORT TERM PERIOD.

EXPECT DECENT DEEP LAYER MOISTURE TO REMAIN OVER THE MID ATLANTIC
AND SOUTHEAST STATES...AS SEEN IN PWAT VALUES NEAR OR SLIGHTLY
ABOVE 2 INCHES. WHEN COMBINED WITH WARM TEMPERATURES PEAKING IN
THE LOW TO MID 90S AND MODERATE INSTABILITY...EXPECT SCATTERED
SHOWERS AND THUNDERSTORMS TO DEVELOP BY LATE MORNING/EARLY
AFTERNOON EACH DAY. THE MAJORITY OF CONVECTIVE DEVELOPMENT WILL
OCCUR ALONG AND INLAND OF THE SEABREEZE...ALTHOUGH BOUNDARY
INTERACTIONS AND A WEST/SOUTHWEST SYNOPTIC FLOW COULD ALLOW
THUNDERSTORMS TO PUSH BACK TOWARD THE COASTLINE. WILL INDICATE
PRECIPITATION CHANCES IN THE 30 TO 40 PERCENT RANGE WEDNESDAY
THROUGH FRIDAY...HIGHEST ACROSS INLAND LOCATIONS.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
A SHARPENING TROUGH TO THE NORTH LATE IN THE WEEK WILL HELP SLOWLY
PUSH A COLD FRONT SOUTH TOWARD THE AREA THROUGH THE WEEKEND. THE
FRONT SHOULD STALL AND REMAIN NORTH OF THE AREA...AS CLIMATOLOGY
WOULD SUGGEST. HOWEVER...PLENTY OF DEEP MOISTURE AND INSTABILITY
WILL BE FOUND SOUTH OF THE FRONT ACROSS THE LOCAL AREA...SUPPORTING
UNSETTLED CONDITIONS WITH HIGHER THAN NORMAL RAIN CHANCES AND SOME
LOCALIZED HEAVY RAINFALL. LINGERING DEEP TROUGHING WILL RETURN
EARLY NEXT WEEK...WITH MORE TYPICAL RAIN CHANCES FOR THIS TIME OF
YEAR.

HIGH TEMPERATURES WILL BE HELD DOWN CLOSER TO NORMAL LATE IN THE
WEEK...BEFORE POSSIBLY RISING ABOVE NORMAL EARLY NEXT WEEK.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
VFR EXPECTED FOR THE FORECAST PERIOD WITH THE EXCEPTION OF
THUNDERSTORMS. AFTERNOON CONVECTION HAS SHIFTED MAINLY INTO
SOUTHERN SC AND SHOULD SOON INTERACT WITH THE SEABREEZE. BEST
CHANCE FOR TSRA AT KCHS WILL BE PRIOR TO 22Z.

EXTENDED AVIATION OUTLOOK...A WEAK TROUGH OF LOW PRESSURE WILL
ENHANCE CHANCES FOR SHOWERS AND TSTMS THROUGH THE WEEK. MVFR OR
LOWER CONDITIONS ARE POSSIBLE WITHIN ANY TSTMS.

&&

.MARINE...
AN ENHANCED GRADIENT BETWEEN AN INLAND TROUGH AND ATLANTIC HIGH
PRESSURE WILL SUPPORT SLIGHTLY HIGHER WINDS AND SEAS ACROSS THE
MARINE ZONES FOR MID WEEK. THERE IS A SMALL POTENTIAL FOR SMALL
CRAFT ADVISORY CONDITIONS TO BE MET...ESPECIALLY IN CHARLESTON
HARBOR AS WINDS ARE ENHANCED BY THE AFTERNOON SEA BREEZE. A WEAK
COLD FRONT WILL APPROACH FROM THE NORTH BY THE WEEKEND...AND WITH
WEAK LOW PRESSURE DEVELOPING ALONGSIDE...EXPECT A WEAKENING
PRESSURE GRADIENT TO RESULT.

RIP CURRENTS...THE COMBINATION OF ASTRONOMICAL INFLUENCES AND A 2
FT 10 SECOND SWELL WILL SUPPORT A MODERATE RISK FOR RIP CURRENTS
ACROSS THE SOUTHEAST SOUTH CAROLINA BEACHES ON WEDNESDAY. WILL
MAINTAIN A LOW RISK FOR THE SOUTHEAST GEORGIA COASTLINE AT THIS
POINT...HOWEVER SUBSEQUENT FORECASTS MAY NEED TO REASSESS WINDS
AND SWELLS FOR A POTENTIAL UPGRADE TO MODERATE.
