AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
330 PM EDT MON AUG 10 2015

.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...
LATEST REGIONAL RADARS SHOW A LINE OF ORGANIZED STRONG CONVECTION
MOVING INTO FAR NW GA THIS AFTERNOON... AND HIRES MODELS SUPPORT
THIS LINE OF SHOWERS AND THUNDERSTORMS PUSHING ACROSS THE REST OF
NORTH GA THROUGH 8 TO 9 PM THIS EVENING. TIMING TOOL INDICATES THESE
STRONG STORMS WILL PUSH ACROSS THE ATLANTA METRO AREA BETWEEN 6 PM
AND 9 PM THIS EVENING. THESE STORMS ARE EXPECTED TO REMAIN STRONG
AND EVEN A FEW POSSIBLY BECOMING SEVERE THROUGH THE EVENING HOURS
ACROSS NORTH GA WHERE SPC HAS A MARGINAL RISK INDICATED. EXPECT THIS
CONVECTION TO DIVE SOUTH TOWARD THE COLUMBUS AND MACON AREAS DURING
THE LATE EVENING AND EARLY TUE MORNING HOUR... BUT EXPECT A
WEAKENING TREND BY LATE THIS EVENING WITH LOSS OF DAYTIME HEATING.
ALL THIS ACTIVITY IS BEING DRIVEN BY A SERIES OF UPPER DISTURBANCES
THAT WILL HELP PUSH A COLD FRONT INTO NORTH GA BY 6-8 AM TUE
MORNING... THEN ACROSS ATLANTA METRO AREA SOMETIME EARLY-MID TUE
AFTERNOON. ALL THIS WILL WARRANT HOLDING ONTO A CHANCE A SHOWERS AND
THUNDERSTORMS ACROSS THE FORECAST AREA OVERNIGHT... WITH DIMINISHING
RAIN CHANCES EXPECTED ACROSS THE FAR NORTH TUE MORNING AS DRIER AIR
FILTERS IN BEHIND THE FRONT. WILL SHOW A GOOD CHANCE OF SHOWERS AND
THUNDERSTORM ACROSS MUCH OF CENTRAL GA ON TUE WHERE THE FRONT IS
EXPECTED TO PROVIDE A BETTER FOCUS DURING DAYTIME HEATING. MODELS
AGREE ON THE FRONT PUSHING SOUTH OF THE FORECAST AREA TUE NIGHT...
WARRANTING DECREASING POPS OVER CENTRAL GA AT THAT TIME.

RAINFALL AMOUNTS THROUGH TUESDAY WILL GENERALLY RANGE BETWEEN 0.5 TO
1.0 INCHES... SO NO WIDESPREAD FLOOD PROBLEMS ARE EXPECTED.
TEMPERATURES WILL HOLD IN THE 70S TONIGHT FOR MOST AREAS... BUT
SHOULD SEE HIGHS ACROSS PARTS OF NORTH GA ON TUE HOLD IN THE LOWER
TO MID 80S BEHIND THE FRONT... WITH UPPER 80S TO LOWER 90S EXPECTED
SOUTH OF THE FRONT. GUIDANCE IS SHOWING COOLER LOWS FOR TUE NIGHT
FOR AT LEAST NORTH GA... WITH LOWS MOSTLY IN THE 60S NORTH OF
ATLANTA... LOWER 70S ATLANTA AND SOUTHWARD. ENJOY.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
EXTENDED MODELS CONTINUE TO BE IN GOOD CONSENSUS WITH THE COLD
FRONT PUSHING INTO THE SOUTHERN CWA AND INTO SOUTHERN GA IN THE
INITIAL LONG TERM PERIODS. HAVE ONLY MADE MINOR ADJUSTMENTS TO
ACCOUNT FOR LATEST MODEL TIMING. HAVE ALSO MADE SLIGHT CHANGES TO
MAX/MIN TEMPERATURES AND DEW POINTS GIVEN THE LATEST MODEL TRENDS.
PREVIOUS FORECAST DISCUSSION IS INCLUDED BELOW.

/ISSUED 413 AM EDT MON AUG 10 2015/
GUIDANCE IN DECENT AGREEMENT WITH AFOREMENTIONED FRONTAL BOUNDARY
IN THE SHORT TERM LINGERING ACROSS THE SOUTHERN TIER OF THE CWA
FOR TUESDAY NIGHT INTO WEDNESDAY...THEN FINALLY PUSHING JUST SOUTH
OF THE AREA AND BECOMING MORE DIFFUSE THRU THE REST OF THE WORK
WEEK. HAVE TRENDED CHANCE TO SLIGHT POPS ACCORDINGLY AND ADVECTION
OF ABNORMALLY DRY AIR IN FROM THE NW WILL ALLOW FOR A RATHER
PLEASANT WED AND THURS WITH SLIGHTLY BELOW NORMAL HIGHS AND
RESULTANT AFTERNOON RH VALUES IN THE 40S.

FOR FRIDAY INTO THE WEEKEND...A BROAD/WEAK AREA OF LOW PRESSURE
LOOKS TO DEVELOP ACROSS THE NORTHERN GULF OF MEXICO ALLOWING FOR
SOME LOW LEVEL MOISTURE TRANSPORT OFF THE ATLANTIC. HAVE CONTINUED
TO ADVERTISE A RETURN OF SLIGHT TO LOW END CHANCE POPS FOR PORTIONS
OF THE AREA...MAINLY FOR DIURNALLY DRIVEN CONVECTION. NO OTHER CLEAR
FORCING MECHANISM LOOKS TO BE PRESENT SO NOT EXPECTING ANYTHING
WIDESPREAD AND RATHER STAGNANT AIRMASS IN PLACE SO DEVELOPMENT
SHOULD BE TYPICAL SUMMERTIME OUTFLOW DRIVEN. TEMPS SHOULD BE
SLIGHTLY WARMER THAN MIDWEEK BUT CLOSE TO NORMAL OR SLIGHTLY BELOW
WITH ENHANCED CLOUD COVERAGE.
