What happened

The episode as NWS FFC wrote it up.

The upper ridge continued in place across the Southeast, with a weak shortwave pushing down the northwest flow aloft. Once again, scattered to numerous showers and thunderstorms developed and a few of these became severe with downed trees reported. Additionally, thunderstorms produced around two inches of rain in less than two hours in south central Gilmer County. The heavy rain fell over wet ground from previous rain the day before. Rapid runoff caused isolated flash flooding in that area.

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 Atlanta, GA wrote its last area forecast discussion before the first event at Jun 30, 6:25 AM EST, 2 hours 20 minutes earlier.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
725 AM EDT MON JUN 30 2014

.SHORT TERM /TODAY THROUGH TUESDAY/...

LINE OF WEAKENING CONVECTION ASSOCIATED WITH A MODERATE SHORT WAVE
RIDING OVER THE TOP OF THE WEAK UPPER RIDGE IS EXPECTED TO CONTINUE
WEAKENING AS IT SWEEPS ACROSS NORTH GEORGIA THROUGH THE EARLY
MORNING HOURS. THE SYNOPTIC SETUP TODAY REMAINS VERY SIMILAR TO
YESTERDAY WITH GEORGIA ON THE PERIPHERY OF THE WEAK UPPER RIDGE AND
A MODERATE SHORT WAVE RIDING OVER THE TOP ACROSS NORTH AND EAST
GEORGIA. I HAVE CONCENTRATED MY BETTER POPS ACROSS THAT AREA THIS
AFTERNOON BUT HAVE KEPT THE PERCENTAGES LIMITED TO THE MID TO HIGH
CHANCE RANGE FOR NOW. HAD A FEW STORMS REACH THE STRONG TO
MARGINALLY SEVERE LEVEL YESTERDAY AND CANNOT RULE OUT THE SAME THIS
AFTERNOON INTO THE EARLY EVENING...HOWEVER I DO NOT EXPECT
WIDESPREAD SEVERE THUNDERSTORMS. AMPLE PRECIP WATER WILL MAKE HEAVY
RAIN/MINOR FLOODING A POSSIBILITY AGAIN AS WELL. MODELS CONTINUE TO
SHOW THE SLOW...GRADUAL WEAKENING OF THE UPPER RIDGE INTO TUESDAY...
HOWEVER ALL ARE SHOWING A LACK OF THE MID/UPPER-LEVEL SHORT WAVE
FORCING THAT WE SAW YESTERDAY AND ANTICIPATE TODAY...SO I HAVE GONE
WITH A GENERAL LESSENING IN CONVECTIVE COVERAGE.

OVERNIGHT LOW TEMPERATURES ARE EXPECTED TO REMAIN NEAR SEASONAL
NORMALS...WITH AFTERNOON HIGHS REACHING A FEW DEGREES ABOVE IN MOST
AREAS OUTSIDE OF ANYONE WHO GETS SOME EARLY PRECIPITATION. HEAT
INDEX VALUES ARE FORECAST TO REMAIN BELOW ADVISORY LEVELS...BUT ARE
LIKELY TO APPROACH 100-102 ACROSS OUR CENTRAL GEORGIA COUNTIES TODAY
AND TUESDAY. AMOUNT OF CLOUD COVER AND CONVECTIVE COVERAGE WILL HAVE
A NOTICEABLE IMPACT ON WHICH AREAS PUSH THE 100 DEGREE HEAT INDEX
LINE EACH AFTERNOON AND BOTH ARE EXPECTED TO BE SOMEWHAT VARIABLE
TODAY BUT LESS ON TUESDAY.

20

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...

LONG RANGE MODELS CONTINUE TO SHOW HIGH PRESSURE WEAKENING ITS
GRIP TUESDAY NIGHT AND WEDNESDAY AS A LONG WAVE TROUGH DEEPENS
ACROSS THE MS VALLEY REGION. THIS SYSTEM PUSHES A COLD FRONT INTO
THE OHIO AND UPPER TN VALLEY REGIONS BY WEDNESDAY NIGHT. AT THIS SAME
TIME... THE GFS AND ECMWF ARE SHOWING A LOW PRESSURE SYSTEM ALONG
THE EAST CENTRAL FLORIDA COAST TUESDAY NIGHT... AND DRIFTING IT
NORTHWARD TO JUST OFF THE GEORGIA COAST ON WEDNESDAY AND WEDNESDAY
NIGHT. MODELS SHOW FAIRLY GOOD AGREEMENT WITH THE LONG WAVE
TROUGH PUSHING EASTWARD AND PUSHING A COLD FRONT INTO THE LOWER
TN VALLEY ON THURSDAY... WHILE IT ALSO SERVES TO LIFT THE LOW
PRESSURE SYSTEM NORTHEASTWARD AND ALONG THE SOUTH AND NORTH
CAROLINA COASTS ON THURSDAY AND THURSDAY NIGHT. BY FRIDAY... BOTH
MODELS SHOW THE FRONT PUSHING INTO SOUTH GA WITH DRY HIGH PRESSURE
BUILDING IN OVER THE FORECAST AREA BY FRIDAY AFTERNOON. AT THIS
SAME TIME... THE SURFACE LOW OFF THE CAROLINAS LIFTS NORTHEASTWARD
AND TRACKS ALONG THE EAST CENTRAL AND NORTHEAST ATLANTIC COASTAL
AREAS THROUGH SATURDAY...THEN DRIFTING FURTHER OUT TO SEA SATURDAY
NIGHT AND SUNDAY. THIS LOW PRESSURE SYSTEM WILL HAVE TO BE
MONITORED CLOSELY FOR POTENTIAL TROPICAL DEVELOPMENT WITHIN THE
NEXT 3 TO 5 DAYS.

THE APPROACHING COLD FRONT AND POSITION OF THE SURFACE LOW OFF
THE GA COASTS ON WEDNESDAY...THEN ALONG THE CAROLINAS ON THURSDAY
WILL WARRANT A CHANCE POPS FOR MOST AREAS ON WEDNESDAY AND THURSDAY.
THEN AS THE COLD FRONT PUSHES SOUTH ON FRIDAY... EXPECT ADDED HIGH
PRESSURE SUBSIDENCE AND DRY AIR TO HOLD POPS DOWN TO ISOLATED
NORTH AND MAYBE LOW SCATTERED CENTRAL FOR FRIDAY AND SATURDAY...
AND POSSIBLY INTO SUNDAY. AS A RESULT... EXPECTING A NICE QUIET
WEATHER PATTERN FOR THE 4TH OF JULY WEEKEND.

AS FOR TEMPS... HAVE LEANED CLOSE TO A MEX/HPC BLEND FOR THROUGH
THE EXTENDED PERIOD...WITH COOLER HIGHS EXPECTED TO FILTER IN OVER
THE AREA FOR FRIDAY AND SATURDAY BEHIND THE FRONT. 39
