AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
1241 PM EST THU NOV 7 2013

.PREV DISCUSSION... /ISSUED 1018 AM EST THU NOV 7 2013/

UPDATE...
CLOUDS AND CEILINGS HAVE HUNG AROUND LONGER THAN ANY GUIDANCE HAD
FORECAST. RIGHT NOW THE LAMP IS THE ONLY MODEL TO HAVE WHAT
APPEARS TO BE A DECENT HANDLE ON THE CURRENT SITUATION. WITH
STRONG WINDS MOISTURE FROM THE PRECIP AND CAA INTO THE AREA THESE
CLOUDS HAVE STUCK AROUND LONGER THAN EXPECTED. AS SUCH...CHANGED
THE FORECAST HIGH TEMPS AND CLOUD CONDITIONS ACROSS THE AREA
TODAY. THE RAIN HAS GREATLY DIMINISHED LIKE EXPECTED. NO OTHER
CHANGES ARE EXPECTED AT THIS TIME

ARG

PREV DISCUSSION... /ISSUED 744 AM EST THU NOV 7 2013/

SHORT TERM /TODAY THROUGH FRIDAY/...
/ISSUED AT 327 AM EST THU NOV 7 2013/
LATEST SURFACE CHART SHOWS THE EXPECTED COLD FRONT MOVING ACROSS
CENTRAL TN-NORTH AL... AND PROGGED TO PUSH INTO NW GA BY 5-7AM...
ATLANTA 10AM TO NOONISH... COLUMBUS AND MACON AROUND 1-3 PM THIS
AFTERNOON. RADAR SHOWS AN AREA OF MOSTLY LIGHT RAIN ALONG AND AHEAD
OF THE FRONT...AND ALREADY PUSHING ACROSS NW AND NORTH CENTRAL GA.
TIMING TOOL INDICATES THE LIGHT RAIN FIELD WILL MOVE ACROSS THE
ATLANTA METRO AREA BETWEEN 6-11AM THIS MORNING... WITH CLEARING
CONDITIONS EXPECTED FAIRLY QUICKLY BEHIND THE FRONT. RAINFALL
AMOUNTS WILL BE LIGHT... GENERALLY LESS THAN ONE QUARTER INCH.
EXPECT THE LIGHT RAIN FIELD TO GRADUALLY WEAKEN/DISSIPATE AS IT
PUSHES INTO CENTRAL GA TODAY... WARRANTING ONLY A SLIGHT CHANCE OF
RAIN FOR AREAS GENERALLY SOUTH OF ATLANTA... WITH MANY AREAS
POSSIBLY ONLY SEEING A FEW SPRINKLES AT BEST. THE TRAILING RIDGE OF
HIGH PRESSURE IS DIVING OUT OF CANADA... SO DO EXPECT STRONG GUSTY
WINDS AND A SHARP COOL DOWN BEHIND THE FRONT. SHOULD SEE NW WINDS
GUST TO NEAR 30 MPH AT TIMES THIS AFTERNOON AND EARLY EVENING. THIS
WILL MAKE MID EVENING TEMPERATURES FEEL LIKE 40S FOR ATLANTA
NORTHWARD... SO BUNDLE UP THIS EVENING IF GOING OUT. EXPECT 5 TO 10
MPH WINDS TO PERSIST OVERNIGHT. THIS WILL GREATLY HINDER FROST
DEVELOPMENT DESPITE LOWS DIPPING INTO THE MID 30S ACROSS MOST OF
NORTH GA. NEVERTHELESS... WILL CONTINUE TO INCLUDE WORDING FOR
PATCHY FROST ACROSS PARTS OF NORTH GA TOWARD MORNING AS WINDS MAY
SUBSIDE JUST ENOUGH TO ALLOW A FEW PATCHES IN PROTECTED COLD SPOTS.
HIGH PRESSURE WILL SETTLE OVER THE AREA ON FRIDAY...RESULTING IN
LIGHT WINDS AND AMPLE SUNSHINE. DESPITE SUNNY SKIES... AFTERNOON
TEMPS WILL STRUGGLE TO GET OUT OF THE 50S NORTH... AND INTO THE
LOWER TO MID 60S FURTHER SOUTH. A MAV AND MET BLEND OF TEMPS LOOKED
REASONABLE THROUGH THE SHORT TERM.

39

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
/ISSUED AT 327 AM EST THU NOV 7 2013/
LONG TERM BEGINS WITH SFC HIGH PRESSURE THAT IS CENTERED OVER THE
VIRGINIA/NORTH CAROLINA AREA DOMINATING ACROSS THE CWA. THIS
WEAKENS AND SHIFTS EASTWARD OVER THE WEEKEND...HOWEVER ANOTHER
RIDGE OVER THE CENTRAL CONUS SHIFTS EAST AND DOMINATES THROUGH THE
FIRST HALF OF NEXT WEEK. IN THE TUESDAY TO WEDNESDAY TIME FRAME...A
SHORTWAVE DEEPENS IN THE TROUGH AND BECOMES A CUTOFF LOW ON
WEDNESDAY. THIS BRINGS THE ONLY CHANCE OF RAIN IN TO THE EXTENDED.
HELD OFF ON THE MENTION OF POPS FOR TUESDAY NIGHT SO ONLY MENTION
OF PRECIP IN THE EXTENDED IS ON WEDNESDAY WITH A SLIGHT CHANCE OF
RAIN NORTH AND CENTRAL AND A CHANCE OF RAIN ACROSS THE EXTREME
NORTH. ECMWF IS A LITTLE SLOWER WITH THE SYSTEM AND IS MORE
LIMITED IN TERMS OF PRECIP COMPARED TO THE GFS.

11

FIRE WEATHER...
/ISSUED AT 327 AM EST THU NOV 7 2013/
A MUCH DRIER AIRMASS WILL SPREAD OVER THE REGION THIS AFTERNOON AND
OVERNIGHT. AS A RESULT... A FEW AREAS ACROSS MAINLY NE AND EAST
CENTRAL GA COULD SEE A FEW HOURS OF CRITICALLY LOW RH VALUES FRIDAY
AFTERNOON. HOWEVER... WINDS WILL BE LIGHT AND STILL SOME UNCERTAINTY
ON DRYING OF FUELS. THEREFORE... WILL CONTINUE TO MONITOR FUELS
THROUGH THE AFTERNOON AND POST ANY FIRE STATEMENTS/WARNINGS TONIGHT
FOR FRIDAY AFTERNOON IF FUELS AND EXPECTED RH VALUES WARRANT.

39

.AVIATION...
18Z UPDATE...
CLOUDS HAVE HUNG AROUND LONGER THAN FORECAST. THIS MEANS THAT MVFR
CEILINGS ARE STILL AFFECTING THE AREA. CLOUDS ARE STARTING TO
SCATTER OUT FROM THE NORTH...EXPECT THIS TO CONTINUE UNTIL WE HAVE
SKC AREA WIDE. EXPECT THE GUSTS TO DIE DOWN AFTER SUNSET TODAY.
TOMORROW HIGH PRESSURE MOVES INTO THE AREA AND CAUSES OUR WINDS TO
COME NNE IN THE LATE AM. WOULDNT BE SURPRISED IF THE WINDS DANCED
AROUND 340-030 DURING THE DAY...THE UNFORTUNATE PART IS THAT THE
WINDS WILL BE AROUND 10 KTS.

//ATL CONFIDENCE...18Z UPDATE...
MEDIUM CONFIDENCE ON TIMING OF CEILINGS....HIGH ON ALL OTHER
ELEMENTS
