AREA FORECAST DISCUSSION...UPDATED FOR AVIATION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
740 AM EDT WED MAY 27 2015

.SHORT TERM /TODAY THROUGH THURSDAY/...
TUESDAYS SHORT WAVE HAS DRIFTED MOSTLY TO THE EAST BUT A PORTION OF
IT MAY TRAIL ACROSS THE CENTRAL ZONES TODAY. MODELS CONSISTENT IN
SHOWING A BRIEF PERIOD OF DRYING MAINLY NORTH TODAY. HAVE REDUCED
THE POPS FOR THE DAY ACROSS THE NORTH...BUT WITH AFTERNOON HEATING
AND REMNANTS OF THE SHORT WAVE...LIKELY POPS LOOK OKAY FOR CENTRAL
ZONES THIS AFTERNOON. HEAVY RAIN AND STRONG WINDS SHOULD BE THE MAIN
THREATS. THURSDAY LOOKS UNSETTLED WITH LINGERING MOISTURE AND
INSTABILITY. NO REAL FEATURE TO FOCUS ON EXCEPT SOME WEAK RIPPLES IN
THE SOUTHWEST FLOW. SO GENERALLY HAVE CHANCE POPS FOR THE DAY MOST
AREAS...35 TO 45 PERCENT.

HAVE ADDED A MENTION OF FOG THIS MORNING AS SOME PLACES HAVE DROPPED BELOW
3 MILES VISIBILITY. NOT THINKING DENSE FOG WILL BE WIDESPREAD
ENOUGH FOR AN ADVISORY.

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
A MOIST AIRMASS WILL CONTINUE OVER THE AREA TO START THE LONG TERM
WITH A MUCH WEAKER SW FLOW ALOFT. PRECIP CHANCES ARE EXPECTED TO
HAVE A MORE DIURNAL TENDENCY WITH THE HIGHEST CHANCES OVER N GA
THURSDAY NIGHT AND FRIDAY WITH SOME DRIER AIR MOVING OVER PORTIONS
OF CENTRAL GA.

THE TENDENCY TO FAVOR N GA WITH THE HIGHEST POPS CONTINUES SATURDAY
AS THE RIDGE ALOFT BUILDS SOME ON SATURDAY FAVORING CENTRAL GA.
SLIGHTLY INCREASED SW FLOW ALOFT ON SUNDAY WILL FAVOR ONCE AGAIN N GA
WITH THE HIGHEST POPS AND THIS IS WHERE THE BEST MOISTURE AND INSTABILITY
WILL BE...AS WILL BE THE CASE FOR FRIDAY AND SATURDAY.

INCREASED DEEPER MOISTURE MONDAY AND TUESDAY WILL ALLOW FOR CHANCE TO
LIKELY POPS ACROSS THE AREA AS AN UPPER TROUGH DRIFTS TOWARD THE STATE.
THE EUROPEAN BRINGS THE TROUGH TO GA WHILE THE GFS HOLDS THE TROUGH
OVER THE LOWER MS VALLEY.

TEMPERATURES RUNNING AROUND TO SEVERAL DEGREES ABOVE NORMAL THROUGH
THE LONG TERM.
