.UPDATE...
MORNING SHOWER ACTIVITY WILL CONTINUE TO DIMINISH OVER THE NEXT
COUPLE OF HOURS. SCATTERED SHOWERS AND THUNDERSTORMS WILL
REDEVELOP BY THE EARLY AFTERNOON WITH DAYTIME HEATING. WITH HIGH
PWATS ACROSS THE AREA AND LIGHT WINDS ALOFT...LOCALLY HEAVY
RAINFALL WILL BE THE PRIMARY THREAT.

UPPER RIDGING BEGINNING TO BUILD INTO THE REGION BY FRIDAY. AMPLE
MOISTURE FOR AT LEAST SCATTERED...MAINLY DIURNAL...CONVECTION

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...

FORECAST RATIONALE FOR THE EXTENDED STILL HOLDS TRUE WITH DRIER

NOT AS CLEAR CUT AS ONE WOULD THINK WITH A 594DM UPPER HIGH.
DESPITE THE OVERALL SUBSIDENCE...MODELS CONTINUE TO INDICATE AMPLE
MOISTURE UNDER THE RIDGE AND OMEGA DURING THE AFTERNOONS.
EXPERIENCE SAYS MODELS ARE WAY OVERDOING THIS ASPECT OF THE
FORECAST BUT NOT CONFIDENT ENOUGH TO REMOVE POPS COMPLETELY. WILL
MAINTAIN ISOLATED RAIN CHANCES THROUGH MUCH OF THE EXTENDED
PERIOD. OTHERWISE THE STORY WILL BE THE HEAT WITH EXTENDED
GUIDANCE CATCHING UP AND NOW INDICATING SOME MID TO CLOSE TO UPPER
90S FOR CENTRAL GEORGIA EARLY NEXT WEEK. NO REASON NOT TO FOLLOW
SUIT GIVEN STRENGTH OF RIDGE AND WILL ADJUST GRIDS AS SUCH WITH
THIS ISSUANCE.
