Damaging Winds in Georgia, March 8, 2005

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
310 AM EST TUE MAR 8 2005

.SHORT TERM /TODAY THROUGH THURSDAY/...STRONG COLD FRONT GATHERING
STEAM OVER GA/AL WILL MOVE RAPIDLY THROUGH THE CWA THIS MORNING.
SHOWERS AND MAYBE A THUNDERSTORM WILL END FROM WEST TO EAST. STRONG
GUSTS TO 50 MPH ARE POSSIBLE WITH ANY CONVECTION ALONG THE FRONT
MIXING DOWN VERY FAST WINDS IN THE LOW LEVELS.

BEHIND THE FRONT...STRONG COLD ADVECTION WILL SETTLE IN BY LATE
MORNING. BRISK WINDS WILL CONTINUE TO MIX DOWN THROUGH MID DAY WITH
GUSTS TO 45 MPH OR HIGHER IN SPOTS. I HAVE REISSUED THE WIND
ADVISORY FOR TODAY.

WINDS DROP QUICKLY THIS EVENING AS LOW PULLS RAPIDLY AWAY AND WEAK
HIGH TRIES TO BUBBLE INTO THE AREA. WITH CLEAR SKIES AND LOW DEW
POINTS...TEMPS WILL SETTLE OUT IN THE LOWER 30S OVER THE NORTH AND
INTERIOR. NOT CONFIDENT ENOUGH OF TEMPS GETTING TO FREEZING TO PUT
UP WARNINGS AT THIS POINT...BUT WILL MENTION IN ZONES AND HWO. DAY
SHIFT CAN LOOK AT ANOTHER SET OF MODEL RUNS BEFORE PULLING THE
TRIGGER.

WEDNESDAY WILL BE PARTLY SUNNY AND COOL WITH ARCTIC AIR MASS IN
PLACE. AFTERNOON TEMPS WILL BE ABOUT 10 TO 15 DEGREES BELOW.

WEDNESDAY NIGHT A WEAK CLIPPER DIVES ALL THE WAY INTO THE EASTERN
GULF OF MEXICO...THROWING A SHIELD OF CLOUDS INTO THE AREA. LOW
LEVELS WILL BE QUITE DRY...SO 20 POPS AT BEST SHOULD DO IT. 850
TEMPS SUPPORT FROZEN PRECIP...BUT LOW LEVEL THICKNESSES ARE TOO
WARM. THE SYSTEM SHOULD MOVE INTO THE ATLANTIC THURSDAY...AND MOST
OF THE CLOUDS SHOULD MOVE AWAY AS WELL.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...ANOTHER CLIPPER SYSTEM WILL
MOVE THROUGH THE NORTHEASTERN U.S LATE FRIDAY AND FRIDAY
NIGHT...DRAGGING A WEAK COLD FRONT THROUGH. UPPER LEVEL DYNAMICS ARE
MUCH FARTHER NORTH WITH THIS SYSTEM...SO CHANCE OF RAIN LOOK TO BE
ON THE LOW SIDE.

FAIR AND MILDER CONDITIONS ARE EXPECTED OVER THE WEEKEND. ONLY FLY
IN THE OINTMENT WOULD BE THE POSSIBILITY OF A BACK DOOR COLD FRONT
SLIPPING INTO SC ZONES...COOLING US DOWN AND INTRODUCING LOW CLOUDS
LATE SUNDAY. HAVE NOT GONE WITH THAT SOLUTION YET...BUT CHANGES MAY
NEED TO BE MADE WITH FUTURE FORECASTS.

&&

.MARINE...DEEP LOW PRES OVER THE MID ATLC REGION TO LIFT NE TO NEW
ENG BY LATE TODAY. BUT CIRCULATION AROUND THE LOW AND HIGH PRES
TRYING TO PUSH E WILL MAINTAIN EXTREMELY STRONG PRES GRADIENT ACROSS
THE AREA. IN ADDITION STRONG CAA GETS UNDERWAY TODAY AND CONTINUES
INTO TONIGHT AS IT WEAKENS. SUFFICE TO SAY THAT GALE WARNINGS THAT
ARE ALREADY IN PLACE WILL REMAIN UP FOR TODAY.

WINDS TO BEGIN TAILING OFF IN CHS HARBOR BY LATE TODAY...BUT WILL
TAKE UNTIL TONIGHT FOR THE DROP IN WINDS OVER THE ATLC. AND
CONSIDERING WE HAVE GALES FOR TODAY...ITS AMAZING THAT THERE MAY
ACTUALLY BE A WEAK RESULTANT SEA BREEZE WED AFTERNOON AND AGAIN THU
AFTERNOON.

LOW PRES MOVING THRU THE GULF OF MEX TOWARD FL WED NIGHT/THU WILL
SHIFT TOWARD THE SW ATLC BY THU NIGHT...WITH NEXT COLD FRONT BY LATE
IN THE WEEK.

&&

.AVIATION...VERY STRONG WINDS AT BOTH TERMINALS TODAY...REACHING
35-45 KT AT TIMES. COLD FRONT THRU BY 13-15Z...PRECEDED BY A BAND OF
SHRA/TSRA...WITH OCCASIONAL IFR CONDITIONS.

IMPROVING CIGS/VSBYS IN WAKE OF FRONT...WITH SKIES BECOMING SKC BY
THIS EVE. WINDS TO DROP OFF DRAMATICALLY BY SUNSET...THEN REMAIN
LIGHT TONIGHT.
