AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
236 AM EST TUE NOV 26 2013

.SHORT TERM /TODAY THROUGH WEDNESDAY NIGHT/...
MODELS CONTINUE IN GOOD AGREEMENT WITH THE CURRENT SYSTEM MOVING
ACROSS THE CWA. RAIN HAS ALREADY SPREAD ACROSS THE NORTHERN AND
WESTERN PART OF THE CWA. SOME OF THE RAIN WAS STILL MIXED WITH
LIGHT SLEET ACROSS NORTH GA BUT THIS WILL END BY DAYBREAK. WILL
THEREFORE CANCEL THE WINTER WEATHER ADVISORY FOR NORTH GEORGIA.
RAIN WILL CONTINUE THROUGH TONIGHT. ALL MODELS BRING THE SURFACE
LOW INTO CENTRAL GA THIS EVENING WITH A DRY SLOT SPREADING ACROSS
THE CWA. THERE WILL LIKELY BE A TEMPORARY END TO THE PRECIP THIS
EVENING ONLY TO HAVE A BRIEF SHOT OF WRAP AROUND MOISTURE SPREAD
ACROSS THE CWA LATE TONIGHT AND WEDNESDAY. THIS IS WHERE THE
PROBLEM BEGINS. VERY STRONG CAA WILL SPREAD ACROSS THE CWA BEHIND
THE SURFACE LOW. TEMPERATURES WILL DROP WITH STRONG NORTHWEST
WINDS SPREADING ACROSS THE CWA AS WELL. THE RAIN WILL BECOME MIXED
WITH AND CHANGE OVER TO SNOW IN EXTREME NORTHWEST GA LATE TONIGHT.
THIS RAIN/SNOW MIX WILL SPREAD ACROSS THE REST OF NORTH GA
WEDNESDAY MORNING BEFORE ENDING BY NOON. THE SOUTHERN EXTENT OF
THE RAIN/SNOW MIX WILL BE FROM NEAR LAGRANGE TO ATHENS. THE ONLY
AREAS EXPECTED TO SEE ALL SNOW ON WEDNESDAY WILL BE THE MOUNTAIN
COUNTIES.

SNOW AMOUNTS...
THIS WILL BE A QUICK SHOT OF SNOW LATE TONIGHT AND WEDNESDAY AS DRY
AIR WILL QUICKLY MOVE INTO THE CWA. AT THIS TIME EXPECT A DUSTING TO
A HALF INCH NORTH OF A ROME TO CLEVELAND LINE WITH 1 TO 2 INCHES
ACROSS THE HIGHER ELEVATIONS OF THE MOUNTAINS. THERE IS STILL A LOT
OF UNCERTAINTY TO THESE AMOUNTS AND WILL THEREFORE HOLD OFF ON
ISSUING A WINTER WEATHER ADVISORY.

THUNDERSTORMS...
MODELS CONTINUE TO BRING INSTABILITY INTO CENTRAL GA AHEAD OF THE
SURFACE LOW. SPC GUIDANCE HAS A 5 PERCENT RISK OF HIGH WINDS AND A 2
PERCENT RISK OF TORNADOES. THIS CANNOT BE RULED OUT AS HELICITY WILL
BE HIGH IN THE WARM SECTOR. THIS AREA WILL NEED TO BE WATCH FOR AN
ISOLATED SEVERE STORM THIS AFTERNOON...GENERALLY SOUTH OF A LINE FROM
COLUMBUS TO MACON TO LOUISVILLE.

WINDS...
WITH THE STRONG VORT MAX PASSING TO OUR EAST AND THE VERY
STRONG CAA...WINDS WILL INCREASE TO 20 TO 30 MPH WITH GUSTS OF 30 TO
40 MPH ACROSS MANY LOCATIONS LATE TONIGHT AND WEDNESDAY. SOME
AREAS OF THE MOUNTAINS COULD SEE GUSTS OVER 40 MPH ON WEDNESDAY.
THE MODELS HAVE BEEN VERY CONSISTENT WITH THIS AND THEREFORE THERE
IS A HIGH CONFIDENCE THAT THESE WINDS WILL OCCUR. THE HIGHER WINDS
WILL ENTER NORTHWEST GA AFTER MIDNIGHT...THEN SPREAD ACROSS THE
REST OF THE CWA WEDNESDAY. WILL THEREFORE ISSUE A WIND ADVISORY
FOR EXTREME NORTH GA AFTER MIDNIGHT TONIGHT...AND FOR THE REST OF
THE CWA FOR WEDNESDAY.

17

.LONG TERM /THURSDAY THROUGH MONDAY/...
DRY CONDITIONS WILL PREVAIL THROUGH THE WEEKEND AS WE TRANSITION TO
A MORE ZONAL FLOW WHICH WILL ALSO BRING A SLOW MODERATION IN
TEMPERATURES. TEMPERATURES THURSDAY MORNING SHOULD BE SOME OF THE
COLDEST WE HAVE SEEN SO FAR THIS SEASON WITH READINGS IN THE TEENS
TO LOWER 20S ACROSS NORTH GA AND THE MID TO UPPER 20S ACROSS CENTRAL
GA. BY THE WEEKEND WE SHOULD BE CLOSER TO NORMAL...ALTHOUGH STILL
SEVERAL DEGREES BELOW NORMAL. THE NEXT SYSTEM IS PROGGED BY BOTH THE
GFS AND ECMWF TO BRING ANOTHER CHANCE OF RAIN TO THE CWA MONDAY.

17

&&

.HYDROLOGY...
LATEST HPC GUIDANCE HAS SLIGHTLY LESS QPF FOR THE CWA FOR TODAY
THROUGH WEDNESDAY. HOWEVER AMOUNTS OF 2 TO 2.5 INCHES ARE STILL
POSSIBLE ACROSS NORTH GEORGIA AND WILL THEREFORE MAKE NO CHANGES TO
THE CURRENT FLOOD WATCH.

&&

.AVIATION...
06Z UPDATE...VFR TO IFR CEILINGS AND VSBYS ACROSS THE AREA.
PRECIP IS STARTING TO MOVE INTO THE TAF SITES SO EXPECTING MAINLY
IFR CEILINGS WITH VSBYS FLUCTUATING IN THE AREAS OF HEAVIER
PRECIP. THE CEILINGS SHOULD STAY IFR THROUGH THE TAF PERIOD. WINDS
WILL START OUT OF THE EAST THEN TURN TO THE NW BY 00Z WED. WINDS
SPEEDS WILL STAY IN THE 8 TO 12KT RANGE THROUGH 00Z. THE PRESSURE
GRADIENT TIGHTENS ACROSS THE AREA TONIGHT WITH WINDS GETTING INTO
THE 14 TO 18KT RANGE GUSTING 25-28KT.

//ATL CONFIDENCE...06Z UPDATE...
CONFIDENCE IS MEDIUM TO HIGH FOR ALL ELEMENTS.
