AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
305 AM EST MON DEC 27 2010
.SHORT TERM /TODAY THROUGH WEDNESDAY/...
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/...
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.
