AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
108 AM EST THU JAN 17 2013

.PREV DISCUSSION... /ISSUED 1019 PM EST WED JAN 16 2013/

UPDATE...
NO MAJOR CHANGES TO THE SHORT TERM PORTIONS OF THE FORECAST. I'VE
MADE MINOR TWEAKS TO THE HOURLY TEMPERATURES AND POPS/WEATHER
BASED UPON CURRENT TRENDS. STILL LOOKS LIKE A WINTER EVENT SETTING
UP PARTICULARLY ACROSS THE HIGHER ELEVATIONS OF NORTH GEORGIA AS
AN UPPER LOW ROTATES ACROSS THE AREA. WHILE FURTHER SOUTH WILL NOT
HAVE SIGNIFICANT ACCUMULATIONS DUE TO THE WARM AIR IN PLACE
INITIALLY...THERE WILL BE WINTER WEATHER IMPACTS EXPECTED. SEE THE
WINTER WEATHER MESSAGE /ATLWSWFFC/ FOR DETAILS CONCERNING THE
WINTER STORM WATCH FOR PORTIONS OF NORTH GEORGIA THURSDAY.

PREV DISCUSSION... /ISSUED 653 PM EST WED JAN 16 2013/

SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...
STATIC PATTERN THAT HAS PERSISTED ACROSS THE REGION IS ABOUT TO GET
A SWIFT KICK OUT OF HERE AS A STRONG UPPER LOW/SHORT WAVE APPROACHES
FROM THE WEST. MODELS CONTINUE TO SHOW THIS SYSTEM OPENING UP AND
WEAKENING A BIT AS IT PASSES THURSDAY...BUT PLENTY OF MOISTURE IN
PLACE OVER THE REGION WITH AMPLE COLD AIR TO THE NORTHWEST OF THE
STATE FOR A SHOT OF WINTRY WEATHER ACROSS NORTH GEORGIA. MODERATE
RAIN SPREADS NORTHEAST ACROSS THE FORECAST AREA LATE TONIGHT IN THE
STRONG WARM/MOIST ADVECTION AHEAD OF THE APPROACHING SYSTEM. CURRENT
FLOOD WATCH WILL BE CONTINUED THROUGH THE DAY THURSDAY...SEE THE
HYDRO SECTION BELOW AND THE FLOOD WATCH STATEMENT /ATLFFAFFC/ FOR
DETAILS CONCERNING THE FLOOD THREAT. AS THE UPPER LOW MOVES ACROSS
DURING THE DAY...COLD AIR ALOFT BEGINS TO PROVIDE A SUITABLE
ENVIRONMENT FOR A MIXTURE OF RAIN AND SNOW ACROSS NORTH GEORGIA.
LOWEST LEVELS REMAIN TOO WARM FOR THIS TO REACH THE GROUND INITIALLY
AS WE START THE DAY...BUT COOLER AIR IN THE LOWER LAYERS SPREADS IN
FROM THE NORTHWEST THROUGH THE DAY ALLOWING A RAIN/SNOW MIXTURE TO
SPREAD SOUTHEAST AS WELL...REACHING AS FAR SOUTH AS THE ATLANTA
METRO AREA BY LATE AFTERNOON. WE ARE STILL NOT EXPECTING SIGNIFICANT
ACCUMULATIONS IN THE ATLANTA AREA BUT WILL LIKELY SEE SOME EVENTUAL
ACCUMULATIONS FARTHER NORTH. SEE THE WINTER WEATHER MESSAGE
/ATLWSWFFC/ FOR DETAILS CONCERNING THE WINTER STORM WATCH FOR
PORTIONS OF NORTH GEORGIA THURSDAY.

MOISTURE EXITS QUICKLY THURSDAY NIGHT WITH MUCH COLDER...BUT DRY...
AIR MASS FILLING IN BEHIND.

20

LONG TERM /FRIDAY THROUGH WEDNESDAY/...
MADE ONLY MINOR CHANGES TO TEMPS AND CLOUDS THROUGH THE EXTENDED AS GFS
AND ECMWF CONTINUE TO SHOW GOOD AGREEMENT... WITH A COOL DOME OF DRY
HIGH PRESSURE DOMINATING THROUGH THE LONG TERM. THIS WILL GIVE US
A NORTHWEST FLOW ALOFT... USHERING IN A MUCH DRIER AND COLDER AIR
MASS... WHICH WILL BRING MORE SEASONABLE TEMPERATURES BACK TO THE
REGION FOR THIS WEEKEND AND EARLY NEXT WEEK.

39

HYDROLOGY...
ALL GUIDANCE AND HPC ARE IN FAIRLY GOOD AGREEMENT WITH ANOTHER
ROUND OF 1 TO 2 INCHES OF PRECIP EXPECTED FROM TONIGHT THROUGH
THURSDAY EVENING ACROSS MUCH OF NORTH AND CENTRAL GEORGIA...WITH
SOME ISOLATED HIGHER AMOUNTS POSSIBLE. MANY RIVERS AND STREAMS
ACROSS NORTH GEORGIA CONTINUE TO EXPERIENCE FLOODING... AND WITH
THESE RAINFALL AMOUNTS... EXPECT A FEW MORE TO POSSIBLY EXPERIENCE
FLOODING. THEREFORE... WILL CONTINUE WITH THE FLOOD WATCH FOR
NORTH GEORGIA THAT INCLUDES THE NORTH METRO ATLANTA THROUGH
THURSDAY EVENING. THE RAINS WILL FINALLY PUSH EAST OF THE AREA BY
MID TO LATE THURSDAY EVENING...WITH A MUCH DRIER AIR MASS
SPREADING IN BEHIND A DEPARTING COLD FRONT.  20/39

&&

.AVIATION...
06Z UPDATE...
PRIMARY CONCERN THIS FCST IS CHC FOR FROZEN PRECIP THURS AFTERNOON
AND EVENING. EXPECT PERIODS OF RAIN WITH IFR CIGS AND VSBYS TO
CONTINUE THROUGH THE DAY INTO THE AFTERNOON AFTER WHICH UPPER STORM
SYSTEM WILL MOVE IN AND COOL TEMPERATURES ALOFT. COULD SEE SNOW
MIX WITH RAIN AROUND 22Z NORTH OF ATL TO GVL LINE. SFC WINDS WILL
BE STRONG IN THE AFTERNOON/EVENING AS SFC LOW PRESSURE MOVES
EAST ROUGHLY ALONG I-20/I-85. NORTH GA AIRPORTS WILL SEE NW WINDS
SHIFT TO SW BY 17Z THEN BACK TO NW AROUND 22Z AT 15-20KTS WITH
GUSTS TO 30KTS THRU THE EVENING. PRECIP AND CLOUDS SHOULD CLEAR OUT
RAPIDLY AROUND 03-05Z AS SYSTEM LIFTS OUT.

//ATL CONFIDENCE...06Z UPDATE...
MEDIUM TO LOW CONFIDENCE ON LIKELIHOOD OF SNOW OVER NORTH GA.
HIGH CONFIDENCE ON ALL OTHER ELEMENTS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH AND CENTRAL GEORGIA.

.DAY ONE...TONIGHT...

...FLOODING POTENTIAL CONTINUES ACROSS NORTH GEORGIA TONIGHT...

GULF MOISTURE WILL CONTINUE ACROSS THE REGION THROUGH TONIGHT. A
STATIONARY FRONT ACROSS NORTH GEORGIA WILL BE THE FOCUS FOR
WIDESPREAD RAIN WHICH COULD PRODUCE AN ADDITION 1 TO 2 INCHES
THROUGH TONIGHT. THIS WILL KEEP THE RISK OF FLOODING OF SMALL
STREAMS...RIVERS AND LOW LYING AREAS ACROSS NORTH GEORGIA. FOR THIS
REASON A FLOOD WATCH HAS BEEN ISSUED FOR MUCH OF NORTH GEORGIA
THROUGH THURSDAY EVENING.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY...
RAIN WILL CONTINUE THURSDAY WITH ADDITIONAL AMOUNTS OF UP TO 1
INCH ACROSS NORTH GEORGIA. AMOUNTS WILL BE LIGHTER ACROSS CENTRAL
AND SOUTH GEORGIA.

ARCTIC AIR WILL BEGIN TO SPREAD INTO GEORGIA THURSDAY AFTERNOON.
THIS WILL CAUSE THE RAIN TO CHANGE TO SNOW ACROSS NORTH GEORGIA
THURSDAY AFTERNOON AND INTO THURSDAY EVENING. TWO TO FOUR INCHES
OF SNOW ARE POSSIBLE OVER THE NORTHEAST GEORGIA MOUNTAINS WITH
LESSER AMOUNTS ELSEWHERE. PLEASE REFER TO THE LATEST WINTER
WEATHER ADVISORY.

.SPOTTER INFORMATION STATEMENT...
