Area forecast discussion, Jun 13, 2:41 PM EDT, 1 hour 31 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
241 PM EDT FRI JUN 13 2014

.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...
UPPER TROUGH MOVING ACROSS THE AREA THIS AFTERNOON AND EVENING WITH
AMPLE MOISTURE AND DECENT INSTABILITY CAUSING SCATTERED TO NUMEROUS
SHOWERS AND SCATTERED THUNDERSTORMS...MOSTLY OVER N AND W GA AT
1830Z BUT MOVING EAST ACROSS THE AREA. WITH THE MAIN UPPER TROUGH
PASSING THE FIRST PART OF THE EVENING AND THE LOSS OF DAY TIME
HEATING...THE FEELING IS SHOWERS AND THUNDERSTORMS WILL DIMINISH
AND END DURING THE EVENING...AT LEAST FOR THE MOST PART.

SLOW MOVING COLD FRONT MOVES TO CENTRAL GA OR SO FOR SATURDAY AS AN
UPPER RIDGE BUILDS OVER THE LOW-MID MS VALLEY TOWARD THE OH AND TN
VALLEYS. BEST INSTABILITY FORECAST OVER CENTRAL GA INTO PARTS OF N
GA. THINKING THE BEST CHANCES FOR SHOWERS AND STORMS WILL BE ACROSS
MAINLY CENTRAL GA AND STRONGLY TIED TO THE DIURNAL BUILD UP OF
INSTABILITY AND WITHOUT SIGNIFICANT HELP FROM ANY SHORT WAVES.

SHOWER AND STORM POTENTIAL WILL DIMINISH SATURDAY EVENING.

FORECAST LOW TEMPERATURES NEAR NORMAL TONIGHT AND SATURDAY NIGHT.
FORECAST HIGH TEMPERATURES GENERALLY NEAR NORMAL FOR SATURDAY.

OVERALL CONFIDENCE IS MEDIUM.

BDL

.LONG TERM /SUNDAY THROUGH FRIDAY/...
NO SIGNIFICANT CHANGES MADE TO THE LONG TERM FORECAST GRIDS AT THIS
TIME. WEAK UPPER RIDGING IS FORECAST TO BUILD INTO THE REGION OVER
THE WEEKEND MINIMIZING DIURNAL CONVECTION SOMEWHAT. HOWEVER THE RIDGE
IS FAR FROM DOMINANT ENOUGH TO FULLY SUPPRESS CONVECTION EACH
AFTERNOON AND EVENING. PLEASE SEE PREVIOUS LONG TERM FORECAST
DISCUSSION BELOW.

20

PREVIOUS LONG TERM DISCUSSION/SATURDAY NIGHT THROUGH THURSDAY/...

500MB TROUGH REMAINS ACROSS THE CWFA LATE SATURDAY/EARLY SUNDAY.
MODELS NOW SHOWING RIDGING ALOFT TRYING TO BUILD IN LATE SUNDAY INTO
EARLY MONDAY BUT A WEAKNESS IN THE RIDGING WILL PERSIST INTO EARLY
TUESDAY. THE GFS HAS THE UPPER RIDGING FINALLY BUILDING IN A LITTLE
STRONGER BY MID-WEEK WITH A TROUGH DIGGING ACROSS THE WESTERN
ATLANTIC. THE ECMWF KEEPS THE WEAKNESS IN THE UPPER RIDGING AND
DEVELOPS A LINGERING CLOSED LOW OFF THE GA/FL COAST THROUGH THE END
OF THE WEEK.

AT THE SURFACE...AN OLD FRONTAL BOUNDARY LINGERS ACROSS SOUTHERN GA
INTO MONDAY BEFORE DISSIPATING. FOR THE REMAINDER OF THE WEEK...HIGH
PRESSURE WILL MOSTLY BE IN CONTROL OF THE SENSIBLE WEATHER. A LEE
TROUGH SHOULD DEVELOP BY MID WEEK...WITH ANOTHER POSSIBLE FROPA BY
THE END OF THE WEEK.

OVERALL...NOT REALLY A PATTERN CHANGE FOR THE EXTENDED PORTION OF
THE FORECAST. EXPECT MAINLY AFTERNOON/EVENING SHOWERS AND
THUNDERSTORMS EACH DAY. INITIALLY...THE OLD FRONT SHOULD PROVIDE A
FOCUS FOR CONVECTION EARLY IN THE WEEK BEFORE DISSIPATING.
OTHERWISE...GOOD SOURCES OF CONVECTIVE INITIATION WILL BE THE
SEA BREEZE OR ANY OTHER MESCAL BOUNDARIES PRESENT.
