A line of thunderstorms moved across northeast Georgia ahead of a cold front. An environment of weak wind shear and high instability supported some isolated areas of wind damage with the line.

The episode as NWS GSP wrote it up.
A line of thunderstorms moved across northeast Georgia ahead of a cold front. An environment of weak wind shear and high instability supported some isolated areas of wind damage with the line.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
235 PM EDT THU JUN 13 2013
.SYNOPSIS...
A COLD FRONT WILL CROSS THE AREA LATE THIS AFTERNOON THROUGH THIS
EVENING. DRY HIGH PRESSURE WILL BUILD IN FROM THE NORTH BEHIND THE
FRONT FRIDAY...AND SETTLE ACROSS THE REGION THROUGH THE WEEKEND. THE
NEXT COLD FRONT WILL APPROACH FROM THE NORTHWEST BY THE MIDDLE OF
NEXT WEEK.
&&
.NEAR TERM /THROUGH FRIDAY/...
AS OF 225 PM EDT THURSDAY...SEVERE STORMS ARE JUST BEGINNING TO MOVE
INTO THE NC MTNS. WESTERLY WINDS HAVE INCREASED TO AROUND 50 KTS AT
10KFT ACROSS THE REGION...WITH 0-3KM BULK SHEAR VALUES GENERALLY
RANGING BETWEEN 30-40 KTS. DCAPE VALUES ARE HIGH AND THE ATMOSPHERE
IS SUPPORTIVE OF STRONG COLD-POOL GENERATION. THEREFORE I EXPECT THE
LINE TO SURVIVE IT/S TRIP ACROSS THE MOUNTAINS AND DEVELOP QUICKLY
INTO A SQUALL LINE OVER OR JUST EAST OF THE BLUE RIDGE. THIS SHOULD
RESULT IN WIDESPREAD STRAIGHT-LINE WIND DAMAGE ACROSS THE FORECAST
AREA AS IT RAPIDLY MOVES OFF TO THE EAST-SOUTHEAST. THIS FIRST ROUND
OF STORMS MAY MISS THE SOUTHWEST MOUNTAINS AND EXTREME NORTHEAST
GEORGIA TO THE EAST...THOUGH I WOULD EXPECT ADDITION CONVECTION TO
DEVELOP UPSTREAM AND AFFECT THESE AREAS DURING THE EARLY EVENING
HOURS. BY LATE EVENING THINGS WILL QUIET DOWN CONSIDERABLY AS COLD
FRONT CROSSES THE REGION. FOR FRIDAY IT WILL BE SUNNY AND MUCH LESS
HUMID.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
AT 230 PM EDT THURSDAY...AN UPPER TROUGH WILL BE ALONG THE EAST
COAST ON FRIDAY EVENING...WHILE AN UPPER RIDGE WILL BE OVER THE
LOWER MS RIVER VALLEY. ON SATURDAY THE TROUGH PROGRESSES FARTHER
OFFSHORE...WHILE THE RIDGE BROADENS ACROSS THE GULF STATES. THE
PATTERN DEAMPLIFIES ON SUNDAY...WITH A FLAT RIDGE ACROSS THE
SOUTHERN TIER OF STATES...AND ZONAL FLOW ACROSS THE NORTHERN TIER.
HIGH PRESSURE WILL BUILD INTO OUR AREA FROM THE NW ON FRIDAY NIGHT
AND SATURDAY. MODEL TIME HEIGHTS SHOW LIMITED LOW LEVEL MOISTURE
LINGERING UNDER A MID LEVEL INVERSION...BUT WITHOUT FORCING OR
BUOYANCY TO SUPPORT CONVECTION.
MOISTURE WILL INCREASE OVER OUR AREA ON SATURDAY NIGHT AND SUNDAY ON
THE BACK SIDE OF THIS HIGH PRESSURE...ESPECIALLY OVER THE MOUNTAINS.
THE MID LEVEL CAP REMAINS...BUT IS WEAKER. SMALL POPS WILL MAINLY
FAVOR MOUNTAINOUS TERRAIN...WHERE AN UPSLOPE FLOW MAY ASSIST IN
OVERCOMING THE WEAK CAPPING INVERSION.
TEMPERATURES WILL RUN A FEW DEGREES BELOW NORMAL ON SATURDAY IN THE
WAKE OF A DEPARTING COLD FRONT AS COOL HIGH PRESSURE ARRIVES.
TEMPERATURES WILL MODERATE UPWARD TOWARD NORMAL VALUES ON SUNDAY AS
HEIGHTS RISE ALOFT AND SOUTHERLY LOW LEVEL FLOW SETS UP.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
AT 230 PM EDT THURSDAY...AN UPPER TROUGH BEGINS TO AMPLIFY FROM THE
GREAT LAKES TO THE GULF STATES ON MONDAY. ON TUESDAY THIS TROUGH
REACHES THE CENTRAL AND SOUTHERN APPALACHIANS. ON WEDNESDAY THE
TROUGH REACHES THE EASTERN SEABOARD...AND ON THURSDAY IT MOVES OFF
THE EAST COAST...WHILE AN UPPER RIDGE AMPLIFIES OVER THE PLAINS.
ATLANTIC HIGH PRESSURE WILL EXTEND OVER THE CAROLINAS AND GA ON
MONDAY...WITH A LEE TROUGH EXPECTED EAST OF THE MOUNTAINS. THIS HIGH
PRESSURE WEAKENS ON TUESDAY WHILE A COLD FRONT APPROACHES FORM THE
NW. THE FRONT IS EXPECTED TO CROSS OUR AREA ON TUESDAY NIGHT...
STALLING JUST SOUTH OF OUR AREA ON WEDNESDAY AND THURSDAY.
CONVECTIVE CHANCES WILL IMPROVE AS THE FRONT APPROACHES AND HEIGHTS
FALL ALOFT. ACTIVITY WILL DECREASE BEHIND THE FRONT...BUT WITH THE
BOUNDARY AND ASSOCIATED MOISTURE REMAINING IN THE VICINITY...SOME
ACTIVITY CAN BE EXPECTED TO LINGER IN THE SOUTHERN PORTION OF THE
AREA ON WEDNESDAY AND THURSDAY. TEMPERATURES WILL EXHIBIT A REDUCED
DIURNAL TREND DUE TO CLOUDS AND MOISTURE...WITH HIGHS JUST BELOW
NORMAL...AND LOW A BIT ABOVE NORMAL.
&&
.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
AT KCLT...TIMING THE CONVECTION DEVELOPING OVER ERN TN AT THIS TIME
BRINGS IT ACROSS THE AIRFIELD BETWEEN 20-21 UTC. CONSIDERING THE
SHEAR AND INSTABILITY CHARACTERISTICS OF THE AIRMASS THIS
AFTERNOON...THE STORMS WILL PUT OUT STRONG OUTFLOW BOUNDARIES AND
THEY SHOULD MOVE RAPIDLY TO THE EAST AS THEY EVOLVE. THEREFORE I
THINK THAT TIMING WILL WORK WELL. I DIDN/T ADD GUSTS TO THE TEMPO
GROUP YET...BUT I PROBABLY WILL ONCE I CHAT A LITTLE MORE WITH THE
CWSU AS THERE IS A GOOD CHANCE OF AT LEAST A 40KT GUST WITH THE
LINE...POSSIBLY HIGHER. OTHERWISE WINDS WILL BE GUSTY OUT OF THE
SOUTHWEST AHEAD OF THE LINE...WITH WINDS VEERING AROUND TO WEST AND
THEN NORTHWEST BEHIND THE LINE DURING THE COURSE OF THE EVENING.
GUSTS UP TO 18 KTS OR SO WILL BE POSSIBLE AFTER SUNRISE TOMORROW AS
WE START TO MIX BEHIND A COLD FRONT.
ELSEWHERE...CONDITIONS ELSEWHERE WILL BE THE SAME AS AT KCLT AS A
SQUALL LINE SWEEPS OUT OF THE MOUNTAINS IN A FEW HOUR/S TIME.
OUTLOOK...HIGH PRESSURE WILL BUILD IN THU NITE AND PRODUCE GENERALLY
QUIET WEATHER AND VFR CONDITIONS THROUGH THE WEEKEND.
