AREA FORECAST DISCUSSION...UPDATED FOR AVIATION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
740 PM EDT FRI OCT 9 2015

.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...

NAM... GFS AND ECMWF INITIALIZE WELL AT 18Z WITH THE OVERALL
SYNOPTIC PATTERN... SHOWING STRONG SHORT WAVE ENERGY QUICKLY
APPROACHING THE MID TO LOWER MS VALLEY REGIONS... AND A SURFACE COLD
FRONT PUSHING INTO FAR WESTERN TN. ALTHOUGH THERE IS SOME SUBTLE
DIFFERENCES IN FRONTAL TIMING AND WHETHER THE DRIVING SHORT WAVE
WILL CUT OFF AN UPPER LOW EITHER OVER GA OR THE CAROLINAS SATURDAY
MORNING. THE NAM IS SLOWEST AND MORE AGGRESSIVE... CUTTING OFF THE
UPPER LOW OVER NORTH GA BY MID-LATE SATURDAY MORNING... KEEPING
CLOUDS AND PRECIP AROUND MUCH LONGER THROUGH SATURDAY NIGHT. THE GFS
AND LATEST ECMWF HINT AT CUTTING OFF THE UPPER LOW ALONG THE
CAROLINA COAST EITHER LATE SATURDAY OR EARLY SUNDAY MORNING. EITHER
WAY... STILL EXPECT A COLD FRONT TO PUSH INTO FAR NW GA SOMETIME
AROUND MID THIS EVENING... ACROSS THE ATLANTA METRO AREA SHORTLY
AFTER MIDNIGHT... THEN ACROSS CENTRAL GA THROUGH SATURDAY MORNING
AND POSSIBLY INTO EARLY SATURDAY AFTERNOON. HIRES MODELS SHOW THE
STRONGEST AND GREATER COVERAGE OF CONVECTION... MAINLY SHOWERS WITH
ISOLATED EMBEDDED THUNDERSTORMS... PUSHING INTO NW GA BY MID TO LATE
THIS EVENING... ACROSS THE REST OF NORTH GA THROUGH 3-4 AM SATURDAY
MORNING... THEN WEAKENING AND PUSHING ACROSS CENTRAL GA BETWEEN 5 AM
AND NOONISH ON SATURDAY. INSTABILITIES AND WIND SHEAR VALUES REMAIN
MODEST... SO NO SEVER STORMS ARE EXPECTED. MODELS ARE INCREASING
OVERALL RAINFALL TOTALS A BIT... NOW SHOWING AROUND 1/2 TO 1 INCH
ACROSS NORTH GA AND 1/4 TO 1/2 INCH ACROSS CENTRAL GA THROUGH
SATURDAY EVENING. OF COURSE... ISOLATED HIGHER AMOUNTS ARE POSSIBLE.
AREA CREEKS AND RIVERS SHOULD BE ABLE TO HANDLE THESE AMOUNTS WITH
NO PROBLEM... SO NO SIGNIFICANT FLOOD PROBLEMS ARE EXPECTED. CLOUDS
AND PATCHY LIGHT RAIN WILL LIKELY LINGER ON SATURDAY AND POSSIBLY
SATURDAY NIGHT... AS AMPLE WRAP AROUND MOISTURE/CLOUDS ARE EXPECTED
ON THE BACK SIDE OF THE UPPER LOW. HOWEVER... WILL SHOW GRADUAL
SCATTERING OF CLOUDS FROM WEST TO EAST SATURDAY NIGHT FOR NOW.

OTHERWISE...A MOS BLEND OF TEMPS AND POPS LOOKED REASONABLE THROUGH
PERIOD... WITH CLOUDY AND COOL CONDITIONS EXPECTED... AND DECREASING
RAIN CHANCES ON SATURDAY BEHIND THE FRONT.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
THE EXTENDED FORECAST CONTINUES TO LOOK LARGELY BENIGN. THE NEXT
FRONT WILL PUSH INTO THE REGION MONDAY NIGHT INTO
TUESDAY...BRINGING A CHANCE OF RAINFALL ACROSS PRIMARILY THE
NORTHWESTERN HALF OF THE AREA. NOT LOOKING AT MUCH IN THE WAY OF
RAINFALL TOTALS GIVEN LIMITED MOISTURE AND INSTABILITY. HIGH
PRESSURE WILL DOMINATE FOR THE REST OF THE EXTENDED. PREVIOUS LONG
TERM DISCUSSION FOLLOWS.

RW

PREVIOUS DISCUSSION... /ISSUED 421 AM EDT FRI OCT 9 2015/

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
MODELS ARE IN GOOD AGREEMENT IN THE LONG TERM. THEY START OUT BY
SHOWING THE FRONTAL SYSTEM IN THE SHORT TERM EXITING THE SE CORNER
OF THE STATE SAT NIGHT/SUNDAY MORNING. STILL KEEPING IN A SLIGHT
CHANCE OF PRECIP SUNDAY MORNING BUT THIS SYSTEM IS EXPECTED TO
PUSH OFF THE GA COAST BY DAY BREAK. THERE WILL BE A BREAK IN THE
CHANCE OF PRECIP BEFORE NEXT FRONTAL SYSTEM ENTERS THE AREA TUE.
THIS SECOND FRONT IS MUCH WEAKER AND DRIER AND NOT EXPECTING MUCH
MORE THAN A CHANCE OF PRECIP WITH THIS FRONT ACROSS THE CWA.
INSTABILITIES ARE VERY WEAK AS IT MOVES THROUGH SO KEEPING MOSTLY
SHOWERS IN THE FORECAST. THIS SECOND FRONT BEGINS ENTERING NW GA
BETWEEN 06Z AND 12Z TUES. THIS FRONT PUSHES QUICKLY THROUGH THE
STATE AS A LARGE HIGH PRESSURE CENTER BEHIND IT PUSHES EAST. THIS
FRONT WILL BE EAST OF THE STATE BY 06Z WED AS THIS HIGH PRESSURE
RIDGE BECOMES CENTERED OVER THE WESTERN GULF COAST STATES BY
12-18Z WED. THIS RIDGE IS EXPECTED TO DOMINATE THE WEATHER PATTERN
THROUGH THE END OF NEXT WEEK.
