The episode as NWS CHS wrote it up.
A stationary front in combination with a weakening upper level shortwave resulted in scattered thunderstorm development across southeast Georgia.
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 Jul 10, 1:48 PM EST, 3 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 248 PM EDT SUN JUL 10 2011 .SYNOPSIS... A WEAK SURFACE FRONT WILL DISSIPATE ACROSS THE AREA BY MONDAY. A WEAK AREA OF HIGH PRESSURE WILL THEN BUILD IN FROM THE NORTH THROUGH WEDNESDAY. A COLD FRONT WILL SLOWLY MOVE INTO THE AREA THURSDAY WITH STRONGER HIGH PRESSURE TO MOVE BACK IN FROM THE NORTH FOR THE WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... A SOMEWHAT SLOW START TO THE CONVECTION TODAY AS WE HAVE SEEN A RATHER STUNTED CUMULUS FIELD ON VISIBLE SATELLITE OVER THE LAST FEW HOURS. WATER VAPOR IMAGERY AND OUR 12Z SOUNDING SHOW SIGNIFICANT DRY AIR ABOVE ABOUT 500 MB WHERE THE UPPER RIDGE IS BUILDING ACROSS SOUTH CAROLINA. WATER VAPOR ALSO CLEARLY SHOWS A PRONOUNCED VORT MAX OFF THE SC COAST MOVING SW TOWARD SOUTHEAST GA. A CONVERGENCE AXIS ACROSS CENTRAL AND SOUTHERN GA IS CURRENTLY THE FOCUS FOR THE STRONGEST CONVECTION...MOST OF WHICH IS SOUTH OF OUR FORECAST AREA. THE APPROACHING SHORTWAVE SHOULD HELP FOCUS A BIT MORE ACTIVITY LATER THIS AFTERNOON INTO EARLY THIS EVENING OVER OUR FAR SOUTHERN GA COUNTIES. ELSEWHERE...VERY WARM MID- LEVELS WILL RESTRICT COVERAGE AND INTENSITY OF CONVECTIVE DEVELOPMENT SO THE SEABREEZE AND CONVECTIVE OUTFLOW BOUNDARIES WILL ALLOW FOR ISOLATED/SCATTERED SHOWERS/STORMS. MOST ACTIVITY WILL TAPER OFF AFTER SUNSET BUT WE HELD ONTO SOME 20-30 POPS OVER FAR SOUTHERN AREAS OVERNIGHT SINCE THE APPROACHING SHORTWAVE AND DEEP TROPICAL MOISTURE PLUME COULD PRODUCE A SHOWER OR STORM AT JUST ABOUT ANY TIME. && .SHORT TERM /MONDAY THROUGH WEDNESDAY/... DANGEROUS HEAT AND HUMIDITY TO BE THE MAIN HEADLINES THIS PERIOD AS UPPER HIGH PRESSURE BUILDS ACROSS THE AREA FROM THE WEST AND A WARM/MOIST SOUTHERLY FLOW REMAINS IN PLACE. EXPECT HIGH TEMPS IN THE MID TO UPPER 90S AWAY FROM THE COAST EACH DAY WITH HEAT INDICES REACHING ADVISORY LEVELS /105 DEGREES/ FOR MOST OF THE AREA MONDAY...EXCEPT POSSIBLY THE CHARLESTON METRO...AND THEN THE ENTIRE AREA TUESDAY AND WEDNESDAY. EXPECT LITTLE RELIEF FROM SHOWERS AND THUNDERSTORMS...ESPECIALLY ACROSS SOUTH CAROLINA...UNTIL POSSIBLY WEDNESDAY WHEN COVERAGE COULD BE A BIT GREATER DUE TO A MORE PRONOUNCED LEE SIDE TROUGH OF LOW PRESSURE AND SLIGHTLY LOWER HEIGHTS ALOFT...ALTHOUGH THE SEA BREEZE SHOULD BE LESS OF A FACTOR DUE TO THE STRONGER OFFSHORE LOW-LEVEL FLOW. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... NO SIGNIFICANT CHANGES. STILL SOME DIFFERENCES WITH THE TIMING/STRENGTH OF THE COLD FRONTAL PASSAGE FRIDAY...ALTHOUGH THIS IS NOT SURPRISING GIVEN HOW UNUSUAL SUCH AN EVENT WOULD BE FOR THIS TIME OF YEAR. GENERALLY LOOKS A BIT COOLER...CLOSER TO CLIMO...WITH HIGHER THAN NORMAL RAIN CHANCES FRI-SUN. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... MAINLY VFR CONDITIONS WILL PREVAIL TODAY AT KCHS AND KSAV. HOWEVER...HAVE INCLUDED CBS ALONG WITH VCSH FOR BOTH SITES AS CONVECTION DEVELOPS ALONG THE SEA BREEZE AND OTHER BOUNDARIES THIS AFTERNOON. STILL...OVERALL COVERAGE OF CONVECTION REMAINS UNCERTAIN. THEREFORE WILL EXCLUDED ANY MENTION OF TSRA FOR NOW...BUT BRIEF PERIODS OF MVFR TO POSSIBLY IFR CONDITIONS CAN NOT BE RULED OUT AS CONVECTION DEVELOPS LATER THIS AFTERNOON. LINGERING LOW LEVEL MOISTURE...LIGHT WINDS AND DECREASING CLOUD COVERAGE COULD LEAD TO SOME PATCHY FOG DEVELOPMENT EARLY MONDAY MORNING. ALSO...PATCHY SMOKE COULD ONCE AGAIN ADVECT ACROSS SOUTHEAST GEORGIA OVERNIGHT...POSSIBLY REDUCING VISIBILITIES AT KSAV EVEN LOWER THAN MVFR LEVELS. ANY LINGERING FOG/SMOKE SHOULD DISPERSE BY LATE MORNING. EXTENDED AVIATION...MAIN CONCERN FOR THE TERMINALS MON THROUGH WED IS THE POSSIBILITY OF EARLY MORNING FOG/SMOKE. RIGHT NOW...IT DOES NOT LOOK LIKE WE WILL SEE MAJOR ISSUES WITH VSBYS...BUT CERTAINLY PERIODS OF MVFR WITHIN A COUPLE HOURS OF SUNRISE IS PLAUSIBLE. CONVECTIVE ACTIVITY SHOULD BE MINIMAL THROUGH MID WEEK AND THEN HIGHER THAN NORMAL TOWARD THE END OF THE WEEK WITH A COLD FRONT IN THE REGION. && .MARINE... WINDS WILL BE GENERALLY LIGHT TONIGHT THROUGH TUESDAY WITH WEAK HIGH PRESSURE NEARBY. BY TUESDAY NIGHT AND WEDNESDAY...WINDS WILL PICK UP A LITTLE OUT OF THE SOUTH AND SOUTHWEST AHEAD OF THE NEXT FRONT...BUT STILL NO HEADLINES EXPECTED. A COUPLE MODELS DO SUGGEST A PRETTY SIGNIFICANT SURGE OF WINDS FROM THE NORTH AND NORTHEAST BY THE END OF THE WEEK BEHIND THE FRONT...BUT TIMING DIFFERENCES HAVE MADE ME GO SOMEWHAT CONSERVATIVE FOR THE TIME BEING. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && JRL/RJB
