1230 PM EST MON DEC 27 2010
.UPDATE...
/ISSUED 1039 AM EST MON DEC 27 2010/
CURRENT FORECAST STILL IN LINE WITH FLURRIES ACROSS
MAINLY EXTREME NORTH GEORGIA THIS MORNING. THINK MOST SHOULD BE

THE MOST PART LOOK IN LINE.
49
&&
.SHORT TERM /TODAY THROUGH WEDNESDAY/...
/ISSUED 640 AM EST MON DEC 27 2010/
LATEST SATELLITE IMAGERY AND SURFACE ANALYSIS SHOW A LARGE UPPER
LEVEL LOW AND THE ASSOCIATED SURFACE LOW NEARLY VERTICALLY STACKED
ALONG THE NORTHEAST ATLANTIC COASTAL REGION. WRAP AROUND MOISTURE
AND CLOUDS CONTINUE TO SPREAD OVER NORTH GEORGIA THIS MORNING...WITH
WEB-CAMS AND AREA OBS INDICATING SCATTERED SNOW FLURRIES CONTINUING
ACROSS THIS AREA...MAINLY ALONG AND NORTH OF A BUCHANAN TO CANTON
TO CLEVELAND LINE. ANOTHER HALF INCH OR LESS OF SNOW IS POSSIBLE
WITH THESE FLURRIES THIS MORNING...ESPECIALLY IN THE HIGHER
ELEVATIONS OF FAR NORTH GEORGIA. WILL INDICATE THIS POTENTIAL IN THE
FORECAST AND HAZARDOUS WEATHER OUTLOOK THROUGH THE MORNING HOURS
TODAY. EXPECT THE MOISTURE AND CLOUDS TO GRADUALLY ERODE THROUGH THE
AFTERNOON...LEAVING MOSTLY CLEAR SKIES FOR MOST OF THE AREA
OVERNIGHT. THIS COUPLED WITH DIMINISHING WINDS SHOULD ALLOW STRONG
RADIATIONAL COOLING TONIGHT. THIS WILL HELP PLUMMET LOWS INTO THE
TEENS AND LOWER 20S FOR MOST OF THE AREA. RESIDENTS ACROSS NORTH AND
CENTRAL GEORGIA ARE ENCOURAGED TO TAKE ACTIONS TO PROTECT
PETS...PIPES... SENSITIVE PLANTS AND MOST OF ALL...CHECK ON THE
ELDERLY. OTHERWISE... MODELS ARE IN GOOD AGREEMENT WITH HIGH
PRESSURE DOMINATING AND PROVIDING A GRADUAL WARM-UP TO MORE
SEASONABLE HIGHS THROUGH WEDNESDAY. LOWS WILL REMAIN COOLER THAN
NORMAL THROUGH THE SHORT TERM. FOR TONIGHT...THE MAV GUIDANCE SEEMED
TOO COLD WHILE MET GUIDANCE A BIT WARM...SO TOOK A BLEND FOR MOST
AREAS.
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
/ISSUED 640 AM EST MON DEC 27 2010/
GFS AND ECMWF ARE HINTING AT AN UPPER DISTURBANCE BRINGING SOME
ISOLATED TO SCATTERED SHOWERS TO THE AREA ON THURSDAY. THIS EXITS
EAST AND SHOULD GIVE US A BREAK ON FRIDAY. BOTH MODELS SHOW A DEEP
UPPER LOW LIFTING OUT OF THE MID PLAINS AND ACROSS THE GREAT LAKES
REGION FRIDAY NIGHT-SATURDAY. THIS WILL GRADUALLY DRAG A WEAKENING
COLD FRONT INTO THE STATE SATURDAY NIGHT-SUNDAY. THEREFORE...EXPECT
INCREASING RAIN CHANCES OVER THE WEEKEND. HOWEVER...NO MENTION OF
THUNDER IS EXPECTED WITH NIL INSTABILITY AND UPPER SUPPORT LIFTING
WELL TO THE NORTH.
