The Greer radar (KGSP), 134 km from the middle of the area, began a volume at 18:10 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Peachtre/Fal Fld, GA (KFFC), launched 12:00Z, 6.1 hours before the alert went out and 185 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

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 Atlanta, GA wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 18, 7:34 AM EDT, 6 hours 33 minutes earlier.

Area forecast discussion, Jun 18, 7:34 AM EDT, 6 hours 33 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
734 AM EDT WED JUN 18 2014

.PREV DISCUSSION... /ISSUED 405 AM EDT WED JUN 18 2014/

SHORT TERM /TODAY THROUGH THURSDAY/...

UPPER RIDGE REMAINS IN PLACE THROUGH THE SHORT TERM BUT WITH A WEAK
BOUNDARY /TAIL END OF A SURFACE FRONT WITH THE ASSOCIATED SURFACE
LOW WAY UP IN MAINE/ SHOWING UP AS AN AREA OF CONVERGENCE ACROSS
NORTH GEORGIA WHICH WILL HELP TO FOCUS CONVECTION THIS AFTERNOON AND
EVENING. FOR NOW IT LOOKS LIKE CONVECTION TODAY WILL BE LIMITED TO
GENERAL PROXIMITY AROUND THIS BOUNDARY...AND SO HAVE LEFT POPS OUT
OF SOUTHEASTERN ZONES. CAPE VALUES FOLLOW SUIT WITH GENERALLY LESS
THAN 600 J/KG MUCAPE ACROSS SOUTHEASTERN ZONES BUT BETWEEN 2000-2500
J/KG ACROSS NORTH GEORGIA. EVEN THOUGH FLOW ALOFT IS WEAK...THE
PRESENCE OF THE SURFACE BOUNDARY WILL ALLOW FOR A FEW STORMS TO
BECOME STRONG AND CANNOT RULE OUT ISOLATED SEVERE...SPC DOES HAVE A
GOOD CHUNK OF NORTH GEORGIA IN THE 5% RISK AREA FOR WIND AND HAIL.
HEAVY DOWNPOURS AND LIGHTNING ARE OF COURSE ALWAYS THREATS WITH
SUMMERTIME CONVECTION.

THE BOUNDARY WILL CONTINUE TO BECOME MORE DIFFUSE AS THE
PARENT LOW PUSHES EVEN FURTHER NORTHEAST AND INTO THE CANADIAN
MARITIMES. FOR THURSDAY...A WEAK SHORTWAVE WILL PUSH THROUGH THE
OHIO VALLEY BRINGING ENOUGH INFLUENCE TO ENHANCE POPS EVEN FURTHER
ON WEDNESDAY. HOWEVER...THOUGH IT LOOKS LIKE THERE COULD BE MORE
COVERAGE OF STORMS ON THURSDAY...WHAT INTENSITY THERE IS TO THEM
TODAY SHOULD DROP OFF FOR TOMORROW WITH CONTINUED REDUCTION IN
INFLUENCE FROM THE SURFACE BOUNDARY.

TEMPS CONTINUE TO HOVER A FEW DEGREES ABOVE SEASONAL NORMALS FOR THE
SHORT TERM WITHOUT MUCH OF A BREEZE SO TAKE IT EASY IF YOU ARE
SPENDING ANY TIME OUTDOORS.

TDP

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...

UPPER RIDGE CONTINUES OVER THE SOUTHEAST AT THE START OF THE
PERIOD BUT BEGINS TO SHIFT TO THE WEST BY THE WEEKEND. THIS LEAVES
THE FORECAST AREA IN A MOSTLY NORTHWEST TO WEST UPPER FLOW AND
MODELS HINT AT SEVERAL IMPULSES MOVING NORTHWEST TO SOUTHEAST INTO
THE SOUTHERN APPALACHIANS. SOME WEAK RIDGING FOR THE FIRST OF THE
WEEK AHEAD OF A SHORT WAVE MOVING TOWARD THE MID MS VALLEY.
GENERALLY A MOIST ATMOSPHERE THROUGH THE PERIOD...BUT LITTLE IN
THE WAY OF DYNAMICS. LOOKS LIKE MOSTLY A DIURNAL PATTERN THROUGH
THE LONG TERM. HAVE FAVORED THE NORTHERN ZONES WITH SLIGHTLY
HIGHER POPS DUE TO THE INFLUENCE OF POSSIBLE SHORT WAVES IN THE
NORTHWEST FLOW. PERSISTENCE TEMPERATURES LOOK OKAY...A BIT WARMER
CENTRAL AND SOUTH.

.AVIATION...
12Z UPDATE...
PATCHY MVFR FOG THIS MORNING SHOULD LIFT WITHIN THE NEXT COUPLE OF
HOURS AS LOW VFR CU 4-5KFT DEVELOPS. EXPECT CONVECTION FOR
NORTHERN TAFS THIS AFTERNOON AND HAVE INTRODUCED TEMPO FOR 19-21Z
FOR BEST GUESS TIMING...OTHERWISE VCSH. WINDS GENERALLY LGT/VRB
BUT FAVORING SW TODAY...SE TONIGHT AND THU MORNING...AND SW TOWARD
THE END OF THE PERIOD AT ATL.
