The toll

Deaths: 0
Injuries: 0
Property damage: $56,000
Crop damage: None recorded
Events: 14

Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.

What happened

The episode as NWS CHS wrote it up.

A very unstable atmosphere was present as hot and humid conditions led to surface based CAPE values between 3000 to 3500 J/KG and low level lapse rates of between 8 to 9 degrees Celsius. Inverted-v soundings and DCAPES between 1000 to 1200 J/KG suggested thunderstorms capable of producing strong downbursts as strong heating occurred during the afternoon and evening hours. Storms first began to initiate during the afternoon along an inland moving seabreeze. The focus then switched to inland areas where a Midland trough was approaching the southeast coastline.

What forecasters said that day

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 Jun 15, 12:45 PM EST, 35 minutes earlier.

Area forecast discussion, Jun 15, 12:45 PM EST, 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
145 PM EDT TUE JUN 15 2010

.SYNOPSIS...
ATLANTIC HIGH PRESSURE WILL PREVAIL THROUGH EARLY NEXT WEEK. A
TROUGH OF LOW PRESSURE WILL LINGER OVER OR NEAR THE AREA THROUGH
WEDNESDAY...WITH VERY HOT AND HUMID CONDITIONS CONTINUING. THE
TROUGH WILL SHIFT CLOSER TO THE COAST LATER IN THE WEEK BEFORE
DISSIPATING...ALLOWING FOR LESS OPPRESSIVE CONDITIONS.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
TEMPERATURES ARE OFF TO A WARM START TODAY UNDER SUNNY SKIES AND
STRONG MID-LEVEL RIDGING. ALONG AND WEST OF US-17 THE DEWPOINTS
HAVE MIXED OUT AS ANTICIPATED BY STATISTICAL GUIDANCE. READINGS
ARE GENERALLY IN THE MIDDLE 70S AT 15Z. WITHIN ABOUT 10 MI OF THE
COAST DEWPOINTS CONTINUE TO HOVER NEAR 80 DEGREES. THESE MUGGY
CONDITIONS COMBINED WITH TEMPS ALREADY IN THE 90S HAVE PUSHED HEAT
INDICES ABOVE 105 IN MANY AREAS. LATEST TWEAKS OF TEMP AND
DEWPOINT GRIDS KEEPS HEAT INDICES ABOVE ADVISORY CRITERIA THROUGH
ABOUT 8 PM. WE ONLY MADE MINOR CHANGES TO HOURLY TEMPERATURES AND MAX
TEMP FORECAST REMAINS ON TRACK. HIGHS INLAND SHOULD TOP OUT AROUND
101 WITH AREAS CLOSER TO THE COAST IN THE 98-100 DEGREE RANGE.

ONE REGION WE ARE WATCHING FOR A POSSIBLE EXCESSIVE HEAT WARNING
IS THE COASTAL SOUTH CAROLINA ZONES. WITH CURRENT DEWPOINTS AROUND
80 WITHIN A COUPLE MILES OF THE COAST...A TEMPERATURE OF 95 WOULD
RESULT IN A 115F HEAT INDEX. OR...AN INCREASE TO 82 DEWPOINT WOULD
ONLY REQUIRE A 92F DRY BULB TO REACH CRITERIA. WE EXPECT TO SEE
DEWPOINTS MIX DOWN A DEGREE OR SO THROUGH 1 PM...BUT AS THE
SEABREEZE BEGINS TO DEVELOP AND PUSH INLAND...DEWPOINTS MAY SURGE.

REGARDING CONVECTION...THERE IS ANOTHER STRONG CAP ACROSS THE AREA
THIS MORNING...SOME 5-6 DEGREES...BUT IT DOES BEGIN TO WEAKEN
EARLY THIS AFTERNOON AS WE REACH OUR CONVECTIVE TEMP IN THE MID
AND UPPER 90S. WITH SUCH HOT AND HUMID CONDITIONS THERE WILL
CERTAINLY BE IMPRESSIVE SBCAPES OVER 3000-3500 J/KG AND LOW LEVEL
LAPSE RATES OF AT LEAST 8-9C. GIVEN INVERTED-V SOUNDINGS AND
DCAPES OF 1000-1200 J/KG THERE IS MOST DEFINITELY A RISK OF
DOWNBURSTS IN ANY T-STORMS THAT BREAK THE CAP AND/OR ADVECT INTO
THE AREA THIS AFTERNOON/EVENING. THUS A COUPLE OF STORMS COULD
BECOME STRONG OR EVEN LOCALLY SEVERE. IN ADDITION...THE STORM
MOTION IS ALMOST NON-EXISTENT TODAY...AND WITH PWATS CLIMBING TO
NEAR 2 INCHES OR GREATER THERE IS CERTAINLY A HEAVY RAIN RISK AS
WELL. LOOK FOR STORMS TO FORM ALONG THE SEA BREEZE BOUNDARY ALONG
THE US-17 CORRIDOR DURING THE MID-LATE AFTERNOON...WITH COVERAGE
INCREASING AS THE BOUNDARY MOVES INLAND. AT THE SAME TIME CONVECTION
WILL ALSO BEGIN TO FORM ALONG THE SURFACE TROUGH...WHICH IS FOUND
ACROSS THE CENTRAL ZONES THIS MORNING...BUT SHIFTS BACK TO THE NW
INTO THE MIDLANDS DURING THE AFTERNOON. SLIGHT CHANCE TO CHANCE
POPS ARE SUFFICIENT FOR TODAY...WITH HIGHEST COVERAGE ACROSS
INTERIOR SE GA.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
WITH PROXIMITY TO THE SURFACE TROUGH OVER THE MIDLANDS...A
BACKDOOR COLD FRONT NEAR THE NC/SC BORDER AND THE INTERACTION OF
THE SEA BREEZE WITH BOUNDARIES FROM NEARBY CONVECTION...SHOWERS
AND T-STORMS WILL LINGER THROUGH AT LEAST THE FIRST PART OF
TONIGHT. SLIGHT CHANCE OR LOW END CHANCE POPS WILL OCCUR
INLAND...HIGHEST ACROSS FAR INLAND AREAS OF SE GA. THERE WILL BE A
LITTLE FOG IN AREAS THAT RECEIVE RAINFALL...AS GEOSTROPHIC WIND
FIELDS FALL TO LESS THAN 10 KT. HOWEVER...THERE LOOKS TO BE TOO
MUCH DEBRIS CLOUDINESS TO ALLOW FOR IDEAL RADIATION CONDITIONS.
THUS NO NEED TO ADD TO THE FORECAST. MIN TEMPS TONIGHT WILL BE
SIMILAR TO RECENT WARM AND MUGGY NIGHTS...FALLING NO LOWER THAN
THE MID AND UPPER 70S INLAND AND STRUGGLING TO FALL TO 80 AT THE
BEACHES.

THE PERSISTENT MID AND UPPER LEVEL RIDGE IN PLACE OVER THE REGION
WILL BEGIN TO FLATTEN ON WEDNESDAY AS A TROUGH PASSES TO THE NORTH
ACROSS THE GREAT LAKES REGION AND INTO NEW ENGLAND. MEANWHILE AT THE
SURFACE...A LEE SIDE TROUGH WILL GRADUALLY SHIFT EASTWARD TOWARD THE
EASTERN MIDLANDS AND CENTRAL SAVANNAH RIVER AREA. WEAKER SUBSIDENCE
AND ENHANCED LOW LEVEL CONVERGENCE WELL INLAND NEAR THE TROUGH WILL
INCREASE THE POTENTIAL FOR CONVECTION ACROSS THE AREA WEDNESDAY
AFTERNOON AND EVENING AS ONGOING UPSTREAM CONVECTION SHIFTS INTO
WESTERN PARTS OF THE FORECAST AREA. CHANCES OF PRECIPITATION RANGE
FROM 30 PERCENT NEAR THE COAST TO 50 PERCENT INLAND. TEMPERATURES
WILL BE SLIGHTLY COOLER ON WEDNESDAY GIVEN THE LOWERING HEIGHTS AND
INCREASE IN CLOUD COVER...BUT WILL STILL BE RATHER OPPRESSIVE WITH
HIGHS RANGING FROM THE MID TO UPPER 90S AWAY FROM THE COOLER
BEACHES. HEAT ADVISORIES MAY BE NEEDED ONCE AGAIN FOR PARTS OF THE
AREA...BUT IT WILL MORE MARGINAL THAN PAST DAYS.

THE RIDGE WILL WEAKEN/FLATTEN FURTHER ON THURSDAY AS THE TROUGH
AMPLIFIES WHILE TRACKING OFF THE NEW ENGLAND COAST...WITH MORE OF A
ZONAL FLOW EXPECTED ACROSS THE REGION. THE WEAKER RIDGING WILL ALLOW
THE INLAND SURFACE TROUGH TO SHIFT NEAR OR EVEN INTO PART OF THE
FORECAST AREA. EVEN WEAKER SUBSIDENCE ALOFT AND THE PROXIMITY OF THE
SURFACE TROUGH WILL ALLOW FOR A SOLID CHANCE OF SHOWERS AND
THUNDERSTORMS ACROSS THE AREA THURSDAY AFTERNOON INTO THURSDAY
EVENING. CLOUD COVER AND COOLER 850 MB TEMPERATURES WILL RESULT IN
HIGHS IN THE LOWER 90S AWAY FROM THE BEACHES...WHICH IS STILL
SLIGHTLY ABOVE NORMAL BUT NO LONGER OPPRESSIVE.

THE MID AND UPPER LEVEL RIDGE WILL BEGIN TO STRENGTHEN ONCE AGAIN
ACROSS THE DEEP SOUTH ON FRIDAY...WHILE THE SURFACE TROUGH SHIFTS
TOWARD THE COAST. SCATTERED AFTERNOON/EVENING SHOWERS ARE EXPECTED
ONCE AGAIN WITH THE TROUGH IN PLACE OVER THE AREA. HIGH TEMPERATURES
MAY BE A DEGREE OR TWO HIGHER WELL INLAND CLOSER TO THE BUILDING
RIDGE...BUT SHOULD OVERALL RANGE FROM THE LOWER TO MID 90S ACROSS
THE AREA.

&&

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
A MID AND UPPER LEVEL RIDGE WILL CONTINUE TO STRENGTHEN WEST OF THE
REGION THROUGH THE WEEKEND...BEFORE SHIFTING OVER THE SOUTHEASTERN
STATES EARLY NEXT WEEK. AT THE SURFACE...ATLANTIC HIGH PRESSURE AND
AN INLAND TROUGH OF LOW PRESSURE WILL PREVAIL. THE SEA BREEZE AND
INLAND TROUGH SHOULD BE SUFFICIENT TO SUPPORT SCATTERED DIURNAL
CONVECTION THROUGH THE LONG TERM PERIOD. TEMPERATURES WILL REMAIN
SLIGHTLY ABOVE NORMAL.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
WIDESPREAD SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS THE
LOWCOUNTRY THIS AFTERNOON. AT LEAST THROUGH 20/21Z THUNDERSTORMS
LOOK LIKELY ON AND OFF AT THE TERMINALS...THUS HAVE WENT AHEAD AND
INSERTED TEMPO TSRA INTO THE TAFS THROUGH THAT TIME PERIOD WITH
GUSTY WINDS UP TO 25 KNOTS. THERE IS ALSO A SLIGHT CHANCE OF A
STRONG TO SEVERE STORM THIS AFTERNOON. IT IS POSSIBLE STORMS WILL
CONTINUE LATER INTO THE AFTERNOON AND AMENDMENTS WILL BE ISSUED AS
NEEDED. CURRENTLY CONTINUE CB THROUGH 02Z WEDNESDAY.

CLOUD COVER WILL BE ON THE INCREASE THROUGH THE AFTERNOON AND
OVERNIGHT AS DEBRIS CLOUDINESS SPREADS OVER THE AREA.
THUNDERSTORMS WILL ONCE AGAIN BE POSSIBLE WEDNESDAY AFTERNOON BUT
DEVELOPMENT WILL LIKELY HOLD OFF UNTIL AFTER 18Z SO STORMS HAVE NOT
BEEN INCLUDED IN THIS TAF UPDATE.

EXTENDED AVIATION OUTLOOK...INCREASING CHANCES OF AFTN/EVE
CONVECTION AT THE TERMINALS THROUGH SAT WHICH MAY RESULT IN MVFR
OR LOWER CONDITIONS...OTHERWISE VFR CONDITIONS EXPECTED.

&&

.MARINE...
RELATIVELY QUITE CONDITIONS ACROSS THE COASTAL WATERS TODAY AND
TONIGHT. MOSTLY WEST AND SW WINDS THIS MORNING WILL BECOME SOUTH AND
SE THIS AFTERNOON...WITH SPEEDS NO MORE THAN 10 OR 15 KT. A VERY
SUBTLE NOCTURNAL SURGE MAY FORM WITHIN THE SOUTH TO SW FLOW
TONIGHT...BUT AGAIN LIMITED TO 10 OR 15 KT. SEAS WILL BE A
COMBINATION OF 1-2 FOOT WIND WAVES MAINLY FROM THE SOUTH OR SW ON
TOP OF A 1-2 FOOT SWELL FROM THE EAST AND SE EVERY 8-9 SECONDS.

WEDNESDAY THROUGH SUNDAY...ATLANTIC HIGH PRESSURE WILL PREVAIL
THROUGH THE WEEKEND...WHILE A TROUGH OF LOW PRESSURE LINGERS INLAND.
THE RESULT WILL BE A SOUTH TO SOUTHWEST FLOW ACROSS THE WATERS.
WHILE WEAK NOCTURNAL SURGING IS POSSIBLE WEDNESDAY NIGHT AND AGAIN
THURSDAY NIGHT...THE GRADIENT WILL BE WEAK ENOUGH THROUGH THE
PERIOD TO KEEP WIND SPEEDS AT 15 KT OR LESS. SEAS WILL BE NO GREATER
THAN 2-3 FT THROUGHOUT THE WATERS.
