The extreme heat event began to subside somewhat on the 2nd as the upper ridge began to weaken, but hot conditions continued. Scattered showers and thunderstorms again developed across the area, but mainly across east central Georgia where a surface trough lingered.

The episode as NWS FFC wrote it up.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
155 PM EDT MON JUL 2 2012
.PREV DISCUSSION... /ISSUED 1112 AM EDT MON JUL 2 2012/
.UPDATE
CLOUDS WILL BE A BIG CONTRIBUTOR IN REDUCING THE MAX TEMP ACROSS
NORTH AND WEST GEORGIA. WHERE SKIES HAVE CLEARED...TEMPS ARE
SURGING...WHERE CLOUDS REMAIN...TEMPS ARE RISING BUT NOT AS QUICK.
CONVECTION CONTINUES OVER ALABAMA WITH A STEADY STREAM OF CIRRUS
MOVING INTO NORTH AND WEST GEORGIA. THESE CLOUDS SHOULD HOLD TEMPS
DOWN A FEW DEGREES FROM PREVIOUS THINKING. HAVING STATED THIS...IF
THE CLOUDS THIN ENOUGH...TEMPS WILL BEGIN START RISING FASTER. WITH
THIS IN MIND HAVE REDUCE MAX TEMPS BY AROUND 4 DEGREES ACROSS NORTH
AND WEST GEORGIA. WITH THE REDUCTION IN TEMPS...HEAT ADVISORY INDEX
WILL REACH 100 TO 103 OVER NORTH AND WEST GA...BUT WITH THE THREAT
OF TEMPS RISING HIGHER IF THE SUN BREAKS THROUGH GIVING A HIGHER
HEAT INDEX...WILL THEREFORE MAINTAIN THE CURRENT HEAT ADVISORY.
HAVE ALSO RAISED POPS ACROSS NORTHWEST GA BASED ON LATEST SHORT TERM
GUIDANCE WHICH SHOWS REINITIALIZATION OF CONVECTION AROUND 20Z AND
AFTER.
&&
PREV DISCUSSION...
SHORT TERM /TODAY THROUGH TUESDAY/...
/ISSUED 432 AM EDT MON JUL 2 2012/
HAVE SEEN AN OVERALL WEAKENING TREND BUT CONVECTION HAS SURE BEEN
SLOW TO DIMINISH OVERNIGHT. IN FACT HAVE EVEN SEEN A FEW STORMS
JUST DEVELOPING IN EASTERN AL. GIVEN OVERALL TRENDS...THINK
STORMS WILL CONTINUE THROUGH SUNRISE AND THEN DIMINISH. STORMS
SHOULD GET STARTED AGAIN LATE IN THE AFTERNOON AND CONTINUE INTO
TONIGHT. TO DRIVE STORMS TODAY...SFC TROUGH IS ACROSS CENTRAL
GEORGIA AND MULTIPLE VORT MAXIMUMS ARE PROGGED IN THE FLOW TODAY
AND TONIGHT. SPC 3HR CALIBRATED SEVERE THUNDERSTORM GUIDANCE SHOWS
HIGHEST VALUES ACROSS CENTRAL GEORGIA. STUCK CLOSELY TO THIS AND
ADVERTISED BEST POPS ACROSS EAST AND CENTRAL GEORGIA. SIMILAR
SITUATION TO YESTERDAY AS OUR CAPE IS VERY HIGH...PARTICULARLY
ACROSS CENTRAL GEORGIA...BUT NEAR ZERO SHEAR. EXPECT TO SEE SOME
SEVERE STORMS AGAIN TODAY WITH BEST CHANCES LATE IN THE DAY. WITH
UPPER RIDGE WEAKENING MORE INTO TUESDAY AND ADDITIONAL SHORTWAVES
IN THE FLOW...WILL CONTINUE THE TREND OF HIGHER THAN SEASONAL
POPS...WITH SEVERE AGAIN A POSSIBILITY.
WITH UPPER RIDGE SLIDING SOUTHWARD AND 850MB TEMPS COOLING ABOUT A
DEGREE THINK MAX TEMPS SHOULD BE A LITTLE COOLER TODAY...BUT STILL
MOSTLY IN THE 100S. WENT ON THE WARM SIDE OF GUIDANCE SO LEANED
TOWARD THE MAV. COMPLICATING FACTOR TODAY WILL BE PRECIP AND JUST
HOW MUCH IT WILL AFFECT TEMPS. YESTERDAY WE WERE ABLE TO REACH OUR
HIGHS BEFORE PRECIP REALLY AFFECTED TEMPS BUT TODAY WE ARE
STARTING WITH TSRA ALREADY ACROSS SOME AREAS. WOULDNT BE SURPRISED
IF SOME PLACES DID NOT REACH THE ADVERTISED MAX TEMP TODAY.
11
&&
.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
/ISSUED 432 AM EDT MON JUL 2 2012/
LONG TERM PERIOD WILL FEATURE STRONG MID AND UPPER LEVEL HIGH
WEAKENING SIGNIFICANTLY AND MORE IMPORTANTLY SINKING SOUTH OVER THE
GULF COAST. BY WEDNESDAY...THIS WILL LEAVE OUR AREA FIRMLY
ENTRENCHED IN WEST TO NORTHWEST FLOW ALOFT...VERY CONDUCIVE FOR
SHORT WAVE INTRUSIONS. SEVERAL OF THESE SHORT WAVES LOOK TO BE ON
TAP AND VERY DIFFICULT TO TIME BUT MOST SIGNIFICANT APPEAR TO BE
WED AFTERNOON AND AGAIN ON FRIDAY AFTERNOON. THESE WILL LARGELY
DRIVE THE POP DISTRIBUTION ON A DAY TO DAY BASIS...BUT DID INDICATE
A GRADIENT FROM SOUTH TO NORTH EACH DAY MAINLY BASED ON MOISTURE
DISTRIBUTION IN PLACE ACROSS THE AREA.
AS FOR SEVERE POTENTIAL...AGAIN MUCH WILL BE SHORTWAVE
DEPENDENT...BUT MODELS DO NOT SHOW MUCH IN THE WAY OF ANY COLD
POOLS MOVING INTO THE AREA. VALUES AT 500MB AVERAGE AROUND -8C TO
-9C...CONDUCIVE FOR SOME SEVERE STORMS BUT NOTHING TO INDICATE
MORE THAN TYPICAL SUMMERTIME CONDITIONS AT THIS TIME. CAPE VALUES
MIRROR THIS FINDING WITH 2000 TO 3000 J/KG EXPECTED EACH DAY WITH
LITTLE SHEAR EXPECTED.

IN ADDITION...MOST STORMS WILL BE CAPABLE OF PRODUCING STRONG TO SEVERE WIND GUSTS DUE TO THE PRESENCE OF ENHANCED DOWNDRAFT PARAMETERS. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY... BORDERLINE HEAT ADVISORY CONDITIONS WILL BE IN PLACE FOR TUESDAY AFTERNOON OVER EAST CENTRAL PORTIONS OF THE AREA.
