AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
325 PM EDT FRI MAY 30 2014

.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...
MAINTAINING A MOSTLY PERSISTENCE FORECAST THROUGH TONIGHT WITH SOME
TWEAKS AS THE 500MB LOW DRIFTS S OVER THE LOWER MS VALLEY.
THIS IS KEEPING GULF MOISTURE OVER THE FORECAST AREA WITH AT LEAST
SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON INTO THE
EVENING...AND DIMINISHING/DISSIPATING WITH THE LOSS OF DAY TIME HEATING.

A BACKDOOR COLD FRONT LOOKS TO MOVE INTO/ACROSS THE AREA
SATURDAY/SATURDAY NIGHT AND SHOULD HELP TO INITIATE SCATTERED SHOWERS AND
THUNDERSTORMS WITH INCREASING DIURNAL INSTABILITY. RATHER STRONG
SURFACE HIGH PRESSURE MOVES TO THE EASTERN SEABOARD SATURDAY NIGHT
AND HELPS TO KEEP RATHER DEEP MOISTURE OVER THE FORECAST AREA IN THE
EAST LOW LEVEL FLOW. SCATTERED SHOWERS AND THUNDERSTORMS WILL
DIMINISH SATURDAY EVENING BUT MAY NOT COMPLETELY DISSIPATE WITH
ABUNDANT MOISTURE STILL FORECAST OVER MUCH OF THE CWA.

FORECAST LOW TEMPERATURES RUNNING 2-5 DEGREES ABOVE NORMAL TONIGHT
AND STAYED CLOSE TO PERSISTENCE FROM LAST NIGHT. FORECAST LOW
TEMPERATURES RUNNING A FEW DEGREES ABOVE NORMAL FOR SATURDAY NIGHT
AS WELL. FORECAST HIGH TEMPERATURES RUNNING CLOSE TO NORMAL FOR
SATURDAY USING A BIAS ADJUSTED MODEL BLEND.

OVERALL CONFIDENCE IS MEDIUM.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
THE EXTENDED PERIOD BEGINS WITH A SURFACE WEDGE NOSING INTO GA
FROM THE NORTHEAST UNDERNEATH GENERAL RIDGING ALOFT..ALBEIT WEAK.
BOTH THE ECMWF AND GFS IN GENERAL AGREEMENT WITH A FEW SCATTERED
STORMS POSSIBLE MAINLY ACROSS THE WESTERN PORTION OF THE
STATE SUNDAY...WEST OF I75 AND NEAR THE WESTERN PERIPHERY OF THE
WEDGE. BY MONDAY...THE SURFACE RIDGE AND ASSOCIATED DRIER AIR
PUSHES ALL THE WAY THROUGH THE REGION RESULTING IN VERY LOW END
RAIN CHANCES ON MONDAY. DEWPOINTS AND TEMPERATURES WILL BE
NOTICEABLY COOLER ON SUNDAY AND MONDAY RUNNING 3 TO 5 DEGREES
BELOW AVERAGE...WITH HIGHS GENERALLY IN THE UPPER 70S TO LOW 80S.

BY TUESDAY AND WEDNESDAY MOST OF THE UPPER LEVEL FEATURES ARE
GONE AS UPPER RIDGING DEVELOPS OVER TEXAS AND WE FALL INTO THE
EASTERN PERIPHERY OF THAT RIDGE WITH A GENERAL NORTH OR
NORTHWESTERLY FLOW ALOFT. MODELS ARE NOT TOO CRAZY ABOUT
WIDESPREAD CONVECTION TUES THROUGH THURS BUT THE PATTERN WOULD
ALLOW A GENERAL RETURN OF TYPICAL SUMMERTIME CONVETION POSSIBLY
ENHANCED BY GULF COAST AND OR ATLANTIC SEABREEZES. BY DAY 7..THE
ECMWF AND GFS DIVERGE IN THE EVOLUTION OF UPPER RIDGING OFF THE
EAST COAST WITH THE ECMWF SHIFTING THE TEXAS RIDGE EAST. THE GFS
HOLDS IT BACK FURTHER WEST. FOR NOW...WILL SIMPLY MAINTAIN LOW END
PRECIP CHANCES FOR THE LATE PERIOD WITH SLIGHTLY ABOVE NORMAL TEMPS.
