AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
1000 AM EST SAT JAN 4 2014

.UPDATE...
NO SIGNIFICANT CHANGES TO FORECAST AT THIS TIME. HAVE INCREASED SKY
COVER FOR TODAY. WITH THIS MUCH CLOUDINESS...MAX TEMPERATURES MAY BE
A BIT TOO HIGH...BUT WILL MONITOR FOR A WHILE. A FEW BREAKS SHOWING
UP ON SATELLITE PICTURES.

41

.PREV DISCUSSION... /ISSUED 455 AM EST SAT JAN 4 2014/

.FREEZING DRIZZLE POSSIBLE SATURDAY NIGHT NORTHEAST
MOUNTAINS......WINTRY MIX CHANGING TO LIGHT SNOW LIKELY OVER EXTREME
NORTH GEORGIA...

SHORT TERM /TODAY THROUGH MONDAY/...
QUIET START TO THE BEGINNING OF THE SHORT TERM AS STRONG HIGH
PRESSURE RIDGE REMAINS ANCHORED OVER THE CAROLINAS WITH RIDGING
THOUGH EAST CENTRAL GEORGIA. LIGHT WINDS ALLOWING FOR DECENT
RADIATIONAL COOLING CONDITIONS WITH TEMPERATURES FALLING INTO THE
LOWER TO MID 20S WITH EVEN A FEW TEENS NOTED AS WELL. BEGINNING TO
SEE THE FIRST SIGNS OF RETURNING MOISTURE IN LATEST FOG CHANNEL IR
SATELLITE IMAGERY WITH INFLUX OF STRATO CU COMING OFF THE ATLANTIC
AND INTO SOUTHEAST GEORGIA. THIS MAY EVENTUALLY CURB TEMPERATURE
DROP FOR MY FAR SOUTHERN ZONES BUT ANY ADDITIONAL IMPACTS WILL BE
MINIMAL FOR THE REMAINDER OF TONIGHT.

INVERTED TROUGH TO DEVELOP OFF THE SE GEORGIA COAST THROUGH THIS
AFTERNOON AND CONVERGENT FLOW WILL GENERATE ADDITIONAL LOW TO MID
CLOUDS FOR THE SOUTHEAST ZONES BUT AGAIN IMPACTS AS FAR AS SENSIBLE
WEATHER WILL BE MINIMAL. DID GO ON THE LOW SIDE OF GUIDANCE FOR
MOST LOCATIONS AS MODEL PLANE FIELDS OF MOISTURE DISTRIBUTION ARE
FASTER IN PROVIDING CLOUD COVER TODAY THAN GUIDANCE WOULD SUGGEST.

STARTS TO GET A LITTLE DICEY OVERNIGHT AS LOW PRESSURE DEVELOPS
FURTHER OFF THE SE COAST AND CONVERGENCE GENERATED BY PERSISTENT
RIDGE BRINGS CIGS DOWN AND ACTUALLY GENERATES SOME DRIZZLE FOR THE
EASTERN HALF OF THE FORECAST AREA. MEANWHILE...TEMPS WILL HAVE
FALLEN TO AROUND FREEZING FOR THE EXTREME NORTHEAST SECTIONS.
ALTHOUGH THERE MAY BE SOME RISING OF TEMPS AS PRECIP
APPROACHES...FEEL THERE WILL BE A FEW LOCATIONS STILL RIGHT AROUND
FREEZING SO HAVE ADDED SOME PATCHY FREEZING DRIZZLE TO THE GRIDS.
NOT ENOUGH AT THIS TIME FOR AN ADVISORY BUT WILL ISSUE AN SPS FOR
POSSIBILITY OF SOME SLICK ROADS.

MODELS IN EXCELLENT AGREEMENT WITH RESPECT TO TIMING OF THE NEXT
SYSTEM WITH CATEGORICAL RAIN CHANCES PUSHING INTO NORTHWEST ZONES
BY 18Z SUNDAY. THIS WILL BE A VERY QUICK MOVING SYSTEM WITH MOST
OF THE IMPACT BEING DONE WITH FOR THE ENTIRE CWA WITHIN A 12 HOUR
PERIOD. WILL BE A VERY INTERESTING 12 HOUR PERIOD THOUGH AS COLD
AIR RUSHES IN ON THE BACK SIDE...CHANGING PRECIP TO A MIXTURE
INITIALLY BUT VERY QUICKLY TO ALL SNOW FOR AREAS NORTH OF A ROME
TO CLEVELAND LINE. STILL A BRIEF MIX POSSIBLE SOUTH OF THIS
LOCATION WITH TOP DOWN METHOD EVEN INDICATING A PERIOD OF FREEZING
RAIN POSSIBLE AS PRECIP ENDS FROM LAGRANGE THROUGH ATLANTA.
AMOUNTS WILL BE TOUGH AS I AM WORRIED HOW RAPIDLY PRECIP PULLS
OUT. GENERALLY 1 TO 2 INCHES SUPPORTED BY THE MODELS AND WPC
GUIDANCE BUT AM LEANING ON THE LOW END AT THIS POINT GIVEN LIMITED
WRAP AROUND INITIALLY. BIGGER ISSUE FOR THESE AREAS WILL BE HOW
QUICKLY TEMPERATURES DROP RELATIVE TO PRECIP ENDING WHICH COULD
CREATE A BLACK ICE SITUATION AT THE WORST TIME...NAMELY MORNING
RUSH HOUR TRAFFIC. WILL HOLD OFF ON WINTER STORM WATCH AT THIS
POINT BUT WILL LIKELY ISSUE EVEN BEFORE AFTERNOON PACKAGE...MAYBE
WITH THE MORNING UPDATE.

DEESE

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
A VERY COLD START FOR THE LONG TERM. HIGH PRESSURE BUILDS IN BEHIND
THE EXITING COLD FRONT WITH A VERY COLD AIRMASS IN PLACE. THE
VERY COLD TEMPS BEHIND THE EXITING FRONT IS EXPECTED FOR MONDAY
THROUGH TUESDAY AS VALUES 15-20 DEGREES BELOW NORMAL ARE POSSIBLE.
MONDAY AND TUESDAY NIGHT LOOK TO BE THE COLDEST TIMES. LOOKING FOR
SINGLE DIGIT TO TEENS MONDAY NIGHT AND TEENS TO 20S TUESDAY
NIGHT. HIGHS TUESDAY ARE LOOKING TO REMAIN BELOW FREEZING FOR MUCH
OF NORTH AND CENTRAL GA. TEMPS WILL REBOUND WED/THU GETTING BACK
TO SEASONAL NORMS BY THU/FRI. MOISTURE BEGINS TO INCREASE ACROSS
THE STATE THU WITH A SHORT WAVE MOVING NORTH OUT OF THE GULF FRI.
HAVE GONE WITH SLIGHT CHANCE TO CHANCE POPS THU/FRI BUT NOT
EXPECTING ANY MIXED OR FROZEN PRECIP AS TEMPS STAY ABOVE FREEZING
FOR THIS SYSTEM.
