AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
130 AM EDT THU AUG 4 2011

.PREVIOUS DISCUSSION.../ISSUED AT 1115 PM EDT WED AUG 3 2011/...

UPDATE...
RUC/NAM HAVE A SLIGHT CONSENSUS ON WHAT TO DO WITH THE CURRENT
CONVECTION OVER TENNESSEE WHICH IS TO BRING IT INTO EXTREME NORTH
GA...THEN DISSIPATE IT RATHER QUICKLY. BASED ON CURRENT TRENDS OVER
EASTERN TENNESSEE...THE CONVECTION HAS BECOME MORE WIDESPREAD
ALTHOUGH THIS COULD BE DUE TO SOME OROGRAPHIC LIFTING. HOWEVER
EXPECT A GOOD PART OF IT TO MAKE IT INTO EXTREME NORTH GA AFTER 06Z.
WILL THEREFORE RAISE POPS TO LIKELY ALONG THE NORTHERN BORDER
COUNTIES. WILL GO WITH THE MODEL TRENDS OF DIMINISHING THE PRECIP AS
IT MOVES FURTHER INTO THE CWA. DUE TO UNCERTAINTY I HAVE A LOW
CONFIDENCE IN THE MODEL SOLUTION.

17
&&

PREV DISCUSSION... /ISSUED 635 PM EDT WED AUG 3 2011/

UPDATE...
UPDATED TO ADD SLIGHT CHANCE POPS EAST CENTRAL THIS EVENING. A FEW
SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP THERE...BUT RAPIDLY
DISSIPATE.

SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
STRONG RIDING ALOFT CONTINUING THROUGH MUCH OF THE SHORT TERM WITH
THE CWA ON THE EASTERN EDGE OF UPPER HIGH. MODELS INDICATE SEVERAL
SHORT WAVES MOVING SOUTHEASTWARD DURING THE NEXT COUPLE OF DAYS.
ALSO WATCHING AN MCS TO OUR NORTH THIS AFTERNOON THAT MAY AFFECT
OUR CWA THIS EVENING OR OVERNIGHT. SLIGHT CHANCE OR CHANCE POPS
LOOK OKAY FOR MUCH OF THE CWA THROUGH THE PERIOD. HARD TO PIN DOWN
ANY ONE AREA THAT MAY BE FAVORED...BUT A WEAK FRONT PUSHING INTO
NORTH GA AREA TOMORROW MAY FAVOR THE NORTH. HOT TEMPERATURES
REMAIN THE BIG STORY TODAY AND HAVE CONTINUED THE HEAT
ADVISORY...ADDING A FEW COUNTIES IN NORTHEAST GA. FRIDAY MAY NOT
BE AS HOT...DEPENDING ON COVERAGE OF CONVECTION AND CLOUDS. MODELS
SHOWING A WEAK UPPER LOW MAY FORM ACROSS THE STATE.

LONG TERM /SATURDAY THROUGH WEDNESDAY/...
HAVE MADE NO CHANGES TO THE EXTENDED EXCEPT ONE TWEAK. ADDED
SLIGHT CHANCE POPS MONDAY NIGHT...MAINLY TO KEEP THE TREND OF
DIURNAL POPS THROUGH THE PERIOD. UNSETTLED WEATHER TO CONTINUE AS
SHORT WAVES AFFECT THE CWA INTO THE MIDDLE OF THE WEEK. AT THIS
POINT...TROPICAL STORM EMILY DOESNT APPEAR TO BE A FACTOR FOR OUR
CWA.

41

.AVIATION...
06Z UPDATE...
MAIN CONCERN IS REMNANT TN MCS AND ASSOCIATED OUTFLOW APPROACHING
FROM THE NORTH. WRF/HRR...AS WELL AS GFS/NAM SHOW THAT THIS ACTIVITY
WILL MAIN ITSELF TO SOME EXTENT AND REACH THE ATL METRO AREA IN THE
08Z-10Z TIME FRAME. LATEST IR SAT SHOWS EXTENSIVE DEVELOPMENT OF AC
FROM ATL-AHN...A SIGN OF INCREASING MID-LEVEL INSTABILITY. FOR
NOW...HAVE SHOWN CB/TS IN THE 08Z-13Z TIME FRAME. EXTENSIVE
MID-LEVEL CLOUDS/SHRA WILL LINGER ACROSS THE AREA THROUGH THE
MORNING HOURS...THEN LIKELY REDEVELOP AS TSRA GENERALLY SOUTH OF
I-20 BY MIDDAY. SOLUTION NOT ENTIRELY CLEAR...BUT IF OUTFLOW MOVES
SOUTH OF ATL-AHN BY MIDDAY...AFTERNOON/EVENING CONVECTION MAY REMAIN
SOUTH OF I-20. CIGS/VSBYS SHOULD REMAIN VFR...EXCEPT MVFR IN/NEAR
SHRA/TSRA. OUTFLOW BOUNDARY SHOULD PROVIDE NW WINDS NEAR 10KTS
TOWARD ATL-AHN 08Z-10Z...THEN WNW-WSW THROUGH REMAINDER OF TAF VALID
PERIOD 5-7KTS.

//ATL CONFIDENCE...06Z UPDATE...
MEDIUM TO HIGH CONFIDENCE IN CIGS AND VSBYS THROUGH TAF VALID PERIOD.
HIGH CONFIDENCE IN WIND DIR/SPD THROUGH TAF VALID PERIOD.
LOW CONFIDENCE IN TIMING AND DURATION OF THUNDERSTORMS THROUGH TAF
VALID PERIOD.
