AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
320 AM EDT SAT MAY 23 2015

.SHORT TERM /TODAY THROUGH SUNDAY/...
HIGH PRESSURE RIDGE CURRENTLY STRETCHES FROM THE CENTRAL GREAT LAKE
DOWN TO THE CENTRAL GULF COAST. HIGH PRESSURE WILL SHIFT OFFSHORE
THE MID ATLANTIC COAST LATER TODAY AS LOW PRESSURE ACROSS THE
CENTRAL US SHIFTS EASTWARD.

CONDITIONS ARE EXPECTED TO REMAIN DRY THROUGH THE PERIOD. MODELS ARE
TRYING TO PRODUCE SOME PRECIP ACROSS THE VERY SOUTHERN TIER OF ZONES
SUNDAY...POSSIBLY IN ASSOCIATION WITH THE EASTERLY FLOW AND/OR
SEABREEZE. CHANCES REMAIN TOO SMALL TO MENTION AT THIS TIME...SO
WILL LEAVE OUT FOR NOW.

TEMPS WILL SLOWLY MODERATE A FEW DEGREES TODAY AND SUNDAY...BUT
REMAIN NEAR NORMAL VALUES FOR THIS TIME OF YEAR.

NLISTEMAA

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
A SERIES OF UPR LVL SHORTWAVES EMBEDDED WITHIN DEEP S/SW FLOW WILL
BEGIN TO AFFECT PORTIONS OF N/CNTRL GA BY MEMORIAL DAY...INCREASING
THE CHANCE FOR SHOWERS/THUNDERSTORMS. EARLY IN THE WEEK...UPR RIDGE
REMAINS FIRMLY IN PLACE ALONG THE CAROLINA/MID ATLANTIC COAST...WITH
A GRADUAL SHIFT TO THE NORTH AND EAST BY MIDWEEK AS EJECTING
LONGWAVE TROUGH CROSSES THE MID MS VALLEY/OHIO VALLEY REGION. THE
POSITION OF THIS RIDGE WILL HAVE AN INFLUENCE ON AREA POPS/COVERAGE
OF CONVECTION...WITH DEEPER MOISTURE/DYNAMICS WEST OF I-75. THE
RIDGE IS NOT EXPECTED TO MOVE MUCH THROUGHOUT THE WEEK AS IT BECOMES
"SANDWICHED" BETWEEN A MIGRATING /WEST/ CUT-OFF LOW IN THE ATLANTIC
AND A DEEP LONGWAVE TROUGH OVER THE WESTERN CONUS.

TOWARD THE END OF THE WORK WEEK (THURS/FRI)...REMNANT DEEPER
MOISTURE PLUME COUPLED WITH WEAK S/W ENERGY AND DAYTIME HEATING
SHOULD SUPPORT AT LEAST SCATTERED DIURNAL CONVECTION. WILL ALSO BE
MONITORING UPR WAVE/LOW NORTHEAST OF THE BAHAMAS AS IT IS PROGGED TO
REMAIN NEARLY STATIONARY INTO NEXT WEEKEND.

TEMPERATURES SHOULD NOT DEVIATE MUCH DAY TO DAY WITH HIGHS GENERALLY
IN THE LOWER TO MID 80S. OVERNIGHT TEMPS WILL GENERALLY BE IN THE
60S TO NEAR 70F AS HIGHER HUMIDITY RETURNS ACROSS THE STATE.
