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 Mar 23, 3:48 PM EDT, 2 hours 25 minutes earlier.

Area forecast discussion, Mar 23, 3:48 PM EDT, 2 hours 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
348 PM EDT FRI MAR 23 2012

.SYNOPSIS...
A COLD FRONT WILL APPROACH SATURDAY AND WILL MOVE THROUGH THE REGION
SATURDAY NIGHT AND EARLY SUNDAY. LOW PRESSURE WILL DEVELOP NORTH OF
THE AREA SUNDAY AND WILL MOVE AWAY FROM THE REGION THROUGH MONDAY.
ANOTHER COLD FRONT WILL PUSH THROUGH THE REGION FROM THE NORTH
MONDAY NIGHT...THEN HIGH PRESSURE WILL BUILD INTO THE THROUGH THE
MIDDLE OF NEXT WEEK. ANOTHER COLD FRONT COULD ADVANCE THROUGH THE
AREA LATE NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
LATE THIS AFTERNOON...SCATTERED SHOWERS AND THUNDERSTORMS JUST TO
THE WEST CONTINUE TO DEVELOP AND SLOWLY MOVE EASTWARD INTO THE
FORECAST AREA. PREVIOUS REASONING FOR AFTERNOON POP TREND SEEMS TO
BE WORKING OUR REASONABLY WELL SO NO ADJUSTMENTS WERE MADE. I STILL
ADVERTISE A PERIOD OF LIKELY POPS ACROSS SE GA LATE THIS
AFTERNOON/EARLY THIS EVENING...WITH A DIMINISHING TREND INTO THE
OVERNIGHT. OVERALL SEVERE THREAT CONTINUES TO BE LOW...BUT AN
ISOLATED STRONG TO SEVERE STORM CANNOT BE TOTALLY RULED OUT. RIGHT
NOW THE ACTIVITY IS MADE OF UP PULSE STORMS WITH SOME DISORGANIZED
MULTICELLS PRESENT. DCAPE VALUES ARE UP TO AROUND 800 ACROSS
PORTIONS OF THE AREA SO SOME THREAT OF GUSTY WINDS AND PERHAPS HAIL
IS POSSIBLE FOR THE STRONGEST STORMS THAT DEVELOP THROUGH THE
AFTERNOON. OTHERWISE...TEMPS WILL LINGER IN THE LOW TO MID 80S OVER
THE NEXT FEW HOURS.

TONIGHT...THE BAND OF DEEPER MOISTURE ASSOCIATED WITH THE AREA OF
SHOWERS AND STORMS AHEAD OF THE MAIN COLD FRONT WILL PROGRESS ACROSS
THE FORECAST AREA AS THE UPPER RIDGE MOVES OFF TO THE EAST IN
RESPONSE TO HEIGHT FALLS FROM THE UPPER LOW. THE SHOWERS/STORMS
ACROSS SE GA THIS AFTERNOON WILL WEAKEN WITH THE LOSS OF HEATING AND
PUSH EASTWARD OVERNIGHT. I HAVE LET THE POPS FALL OFF TO HIGH CHANCE
OVERNIGHT FAVORING AREAS FURTHER TO THE NORTH AND EAST ACROSS THE
TRI-COUNTY AREA. OTHERWISE I THINK WE WILL SEE A RELATIVE LULL IN
SHOWER ACTIVITY THROUGH DAY BREAK. THE OTHER CONCERN FOR THE
OVERNIGHT IS THE POTENTIAL FOR FOG. WITH MOSTLY CLOUDY SKIES IN
PLACE FROM THE ONGOING SHOWERS/STORMS AS WELL AS INCREASING MID/HIGH
CLOUDS SHOULD PREVENT MUCH FOG FROM DEVELOPING. MODEL GUIDANCE
DOESN/T HIT IT TOO HARD AND IT APPEARS BASED OFF SREF PROBS THAT THE
BEST CHANCES FOR FOG WILL BE ACROSS SE GA. THIS AREA COULD SEE SKIES
SCATTER OUT FOR A FEW HOURS CLOSER TO DAY BREAK...BUT ALL IN ALL THE
OVERALL FOG THREAT APPEARS LOW. MIN TEMPS WILL BE QUITE WARM...ONLY
FALLING INTO THE LOW TO MID 60S TONIGHT.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/...
EARLY SATURDAY...AN INITIAL BAND OF ENHANCED/DEEP LAYER MOISTURE WILL
PUSH OFFSHORE...AND A LULL IN PRECIPITATION IS POSSIBLE UNTIL LATE
SATURDAY MORNING/EARLY SATURDAY AFTERNOON. THUS...LOWERED POPS TO
SLIGHT CHANCE/CHANCE FOR A FEW HOURS SATURDAY MORNING. THEN...AS A
SPRAWLING/WELL DEFINED UPPER LOW/ASSOCIATED COLD POOL TURN TOWARD
THE SOUTHEAST...MOISTURE ADVECTION FEATURING PWATS EXCEEDING 1.5
INCHES AND DEEP LAYER FORCING/ASCENT SUPPORTED IN PART BY MID/UPPER
LEVEL HEIGHT FALLS AND MASS DIVERGENCE WILL SUPPORT EXPANDING
COVERAGE OF DEEP/MOIST CONVECTION. DETAILS OF PRECIPITATION SCENARIO
REMAIN SOMEWHAT UNCLEAR. IN GENERAL...GUIDANCE DEPICTS A BAND OF
PRECIPITATION DEVELOPING CLOSE TO THE COAST...WHERE SEA BREEZE
CONVERGENCE WILL OCCUR...WHILE ANOTHER BAND OF CONVECTION DEVELOPS
UPSTREAM WITHIN AN AXIS OF LOW LEVEL CONVERGENCE/CLOSER TO THE UPPER
LOW. IN REALITY...MULTIPLE BANDS OF SHOWERS/THUNDERSTORMS WILL
LIKELY DEVELOP ACROSS THE REGION...THUS AFTERNOON POPS ARE GRADUATED
SLIGHTLY FROM LIKELY INLAND TO CATEGORICAL CLOSER TO THE COAST.

CLOUD COVER AND ASSOCIATED REDUCED INSTABILITY SHOULD LIMIT
THE POTENTIAL FOR SEVERE WEATHER. DESPITE LIMITED SURFACE BASED
INSTABILITY...COOLING MID LEVEL TEMPERATURES/STEEPENING MID LEVEL
LAPSE RATES AND INCREASING 0-6 KM BULK SHEAR WILL SUPPORT
ORGANIZED/MULTICELL THUNDERSTORMS WITH EMBEDDED SUPERCELLS WHICH
COULD PRODUCE ISOLATED DAMAGING WIND GUSTS AND LARGE HAIL ESPECIALLY
SATURDAY AFTERNOON.

SATURDAY NIGHT INTO SUNDAY...THE UPPER LEVEL LOW/ASSOCIATED COLD
POOL AS COLD AS -22C AT 500 MB WILL PROGRESS SOUTHEAST AND SHOULD
PASS DIRECTLY OVER THE FORECAST AREA. AHEAD OF THE UPPER TROUGH
AXIS...NUMEROUS PARAMETERS INCLUDING 500-300 MB Q VECTOR CONVERGENCE
AND INCREASING 700-300 HEIGHT FALLS INDICATE DEEP LAYER
FORCING/ASCENT...SUPPORTING AT LEAST SCATTERED TO NUMEROUS SHOWERS
AND THUNDERSTORMS. WHILE SURFACE BASED DIURNAL/PRECIPITATION INDUCED
STABILIZATION SHOULD OCCUR...STEEP MID LEVEL LAPSE RATES AND DYNAMIC
FORCING SUGGEST THAT THE POTENTIAL FOR ISOLATED SEVERE
THUNDERSTORMS...MAINLY FEATURING A THREAT FOR LARGE HAIL...COULD
CONTINUE THROUGH SATURDAY NIGHT INTO SUNDAY.

AS THE MAIN VORTMAX/CORE OF THE COLD POOL PUSH OFFSHORE SUNDAY
AFTERNOON...PRECIPITATION COVERAGE SHOULD WANE. HOWEVER...IF THE
UPPER LOW ADVANCES MORE SLOWLY THAN EXPECTED AND/OR LOW LEVEL
OFFSHORE FLOW REMAINS SUFFICIENTLY LIGHT...SEA BREEZE CONVERGENCE
AND COLD TEMPERATURES ALOFT COULD SUPPORT ANOTHER ROUND OF
THUNDERSTORMS WITH AN ISOLATED HAIL/DAMAGING WIND THREAT SUNDAY
AFTERNOON.

POPS GRADUALLY DIMINISH BELOW 15 PERCENT SUNDAY NIGHT AND REMAIN
VERY LOW MONDAY. TEMPERATURES SUNDAY SHOULD AVERAGE A COUPLE OF
DEGREES COOLER THAN SATURDAY...THEN TEMPERATURES MONDAY WILL WARM
INTO THE UPPER 70S/LOWER 80S MOST LOCATIONS.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
A DRY COLD FRONT IS EXPECTED TO CROSS THE AREA MONDAY NIGHT...THEN
SURFACE HIGH PRESSURE WILL BUILD FROM THE NORTH TUESDAY.
TEMPERATURES TUESDAY SHOULD TOP OUT A COUPLE OF DEGREES COOLER THAN
MONDAY ALTHOUGH STILL ABOVE NORMAL FOR LATE MARCH. BUILDING HEIGHTS
ALOFT WILL THEN SUPPORT A PERSISTENT SURFACE HIGH THROUGH THURSDAY.
AN ISOLATED SHOWER CANNOT BE RULED OUT TUESDAY NIGHT OR WEDNESDAY
ESPECIALLY OVER THE GA WATERS AS A WEAK COASTAL TROUGH DEVELOPS.
HOWEVER DRY WEATHER WILL FOR THE MOST PART PREVAIL WITH TEMPERATURES
5-8 DEGREES ABOVE NORMAL THROUGH MIDWEEK. A BACKDOOR COLD FRONT WILL
PROBABLY DROP IN FROM THE NORTH THURSDAY NIGHT OR FRIDAY BUT AT THIS
POINT MOISTURE APPEARS TOO LIMITED TO JUSTIFY ANY POPS ABOVE 15
PERCENT.

&&

.AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
NEAR TERM TAF CONCERNS REVOLVE AROUND THE THUNDERSTORM POTENTIAL
THIS AFTERNOON. THE BEST COVERAGE IS EXPECTED TO BE FURTHER WEST
ACROSS SE GA AND CLOSER TO KSAV THAN KCHS. I HAVE ADDED A TEMPO
GROUP FOR SHOWERS AND A CB AT KSAV TO COVER THE LATE AFTERNOON
THROUGH EVENING TIME PERIOD. WHATEVER CONVECTION GETS GOING TO THE
WEST WILL THEN MOVE EASTWARD TONIGHT...THOUGH IT WILL BE A ON
WEAKENING TREND. BY THE TIME IT MAKES IT TO KCHS...IT WILL LIKELY
BE JUST AN AREA OF SHOWERS. I HAVE JUST GONE WITH VCSH FOR NOW AT
KCHS IN THE EARLY MORNING HOURS DUE TO THE UNCERTAINTY WITH HOW
THE CONVECTION WILL EVOLVE. CONDITIONS ARE EXPECTED TO PRIMARILY
BE VFR OVERNIGHT...THOUGH SOME OF THE MODEL GUIDANCE HINTS AT
POTENTIAL MVFR CIGS/VSBYS AT TIMES THROUGH SUNRISE. THIS WILL BE
MOSTLY LIKELY AT KSAV WHERE THE SHOWER/THUNDERSTORM ACTIVITY WILL
WANE THE EARLIEST WITH THE POTENTIAL FOR SOME PARTIAL CLEARING
THEREAFTER. HAVE ADDED A PERIOD OF MVFR FOG FOR NOW BUT IF
CLEARING INCREASES...CONDITIONS COULD BE LOWER.

TOMORROW AS THE FRONT MOVES INTO THE AREA...SHOWERS AND
THUNDERSTORMS WILL INCREASE IN COVERAGE ACROSS THE REGION. HAVE
INTRODUCED SHRA MENTION WITH A CB STARTING AT 15Z. THIS WILL
REQUIRE SOME FINE TUNING AS THE TIME DRAWS CLOSER.

EXTENDED AVIATION OUTLOOK...PERIODIC CIG/VSBY RESTRICTIONS POSSIBLE
SATURDAY NIGHT INTO SUNDAY IN SCATTERED TO NUMEROUS SHOWERS/TSTMS.
THEN...VFR THROUGH MIDWEEK.

&&

.MARINE...
A COLD FRONT AND ASSOCIATED STRENGTHENING LOW LEVEL JET WILL DRAW
CLOSER TO THE LOCAL WATERS TONIGHT. AS IT DOES...WINDS WILL BE ON
THE INCREASE BUT ARE EXPECTED TO STAY BELOW SCA CRITERIA. 10-15 KTS
WILL BE PREVALENT BY THE PRE DAWN HOURS ON SATURDAY. SEAS ARE ALSO
EXPECTED TO REMAIN BELOW SCA CRITERIA...BUT WILL BE ON THE INCREASE
WITH THE STRENGTHENING WINDS. PERSISTENT 2-3 FT SWELL ENERGY WILL
CONTINUE THROUGH SATURDAY MORNING WITH COMBINED SEAS INCREASING TO
2-4 FT WITHIN 20 NM AND 4-5 FT BEYOND.

S/SW FLOW WILL STRENGTHEN SATURDAY INTO SATURDAY NIGHT AS A COLD
FRONT APPROACHES FROM THE WEST. HOWEVER...WINDS SHOULD REMAIN BELOW
SCA THRESHOLDS...AND 6 FT SEAS WILL MOST LIKELY REMAIN OUTSIDE
AMZ374. THEN...AS THE COLD FRONT PUSHES OFF THE COAST AND LOW
PRESSURE DEVELOPS NORTH OF THE WATERS SUNDAY...WINDS WILL BECOME
OFFSHORE BUT WILL REMAIN SOMEWHAT ELEVATED IF STILL BELOW SCA
LEVELS. MONDAY NIGHT...ANOTHER COLD FRONT WILL CROSS THE WATERS FROM
NORTH TO SOUTH AND HIGH PRESSURE WILL BUILD FROM THE NORTH.
INITIALLY...A SURGE OF E/NE WINDS AND BUILDING SEAS COULD PRODUCE A
PERIOD OF SCA CONDITIONS FOR SOME AREAS. HOWEVER...THE HIGH WILL
CONTINUE TO SHIFT SOUTH TUESDAY THROUGH MIDWEEK...AND RELAXING WINDS
WINDS SHOULD BE ACCOMPANIED BY SUBSIDING SEAS.

RIP CURRENTS...MODERATE RISK INTO THIS EVENING. LOW RISK SATURDAY.
