AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
450 PM EST WED NOV 25 2009
.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
A WEAK DRY COLD FRONT IS SWEEPING THROUGH THE STATE AT THE MOMENT
CLEARING THINGS OUT FROM NW TO SE. THIS FRONT WILL USHER IN A
LARGE...MODIFIED MARITIME POLAR AIRMASS OVER THE REGION TONIGHT
ALLOWING TEMPS TO COOL SOME. THE MODELS ARE ALL SHOWING A DEEP 500
MB LOW SWINGING THROUGH THE UPPER MS/GREAT LAKES/OHIO VALLEY TONIGHT
THURSDAY THE BASE OF ITS TROF PUSHES THROUGH GA THU NIGHT/FRI
MORNING BRINGING SOME MOISTURE WITH IT TO EXTREME N GA. LOOKS LIKE
THIS MOISTURE WILL BE MAINLY IN THE FORM OF CLOUDS SO NO PRECIP
EXPECTED WITH THIS SYSTEM. AFTER THIS TROF MOVES EAST OF THE WE STAY
IN DRY WEST TO NWLY UPPER LEVEL FLOW WITH A SURFACE RIDGE BUILDING
IN FROM THE TX/LA GULF COAST FOR THE WEEKEND.
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
WEEKEND WILL BE DRY AND SEASONABLE AS LARGE SFC HIGH BUILDS INTO THE
SOUTHEAST. GFS DEVELOPS A STOUT LOW ACROSS THE GULF COAST...THEN
LIFTS AND DEEPENS IT ACROSS THE APPALACHIANS...IN CONJUNCTION WITH A
WEDGE FRONT ACROSS CENTRAL GA. THIS IS A POTENTIAL COOL SEASON
SEVERE PATTERN FOR US BUT THE GFS IS DECIDEDLY DIFFERENT FROM ITS
ENSEMBLE COUSINS. THEY LIFT THE LOW QUICKLY INTO THE MID-ATLANTIC
STATES AND BOMB IT OUT...KEEPING GA DRY. ECMWF AND CANADIAN MODELS
ARE MORE IN LINE WITH THE OPERATIONAL GFS RUN. WILL LEAN TOWARD
THIS GFS/ECMWF/CANADIAN SOLUTION AND KEEP HIGHER POPS IN FOR MONDAY
AND TUESDAY. STILL A LONG WAY OUT...BUT NEED TO KEEP AN EYE ON
SEVERE THREAT FOR MONDAY NIGHT INTO TUESDAY IF THESE SOLUTIONS ARE
CLOSE.
