AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
300 PM EST FRI FEB 3 2006

.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...DEVELOPING SITUATION
THIS AFTERNOON WITH TWO MAIN SYSTEMS AFFECTING THE SOUTHEAST. ONE IS
AN AREA OF CONVECTION THAT HAS BEEN ACTIVE SINCE THIS MORNING OVER
FLORIDA. THE OTHER MASS OF CONVECTION OVER NORTHERN LOUISIANA HAS
JUST BEGUN TO PROGRESS SLIGHTLY EASTWARD. THE STORMS FURTHER WEST
ARE ASSOCIATED WITH AN UPPER LEVEL SHORTWAVE FORECASTED TO MOVE
NORTHEAST THROUGH THE SOUTHERN APPALACHIANS TONIGHT.

HOW THESE TWO SYSTEMS WILL AFFECT OUR AREA WILL NEED TO BE CLOSELY
WATCHED THROUGH THE AFTERNOON AND EVENING. EXTENSIVE CLOUD COVER HAS
REMAINED OVER COASTAL SC AND GA INTO THE EARLY AFTERNOON AND HAS
BEEN SUPPRESSING TEMPERATURES FOR THE DAY. MODEL GUIDANCE WAS GIVING
HIGHS TODAY IN THE MID 70S...HOWEVER MOST OF THE CWA HAS YET TO GET
OUT OF THE MID 60S. THE LACK OF DAYTIME HEATING MAY INDEED AFFECT
THE CHANCES OF SEVERE WEATHER.

MODEL GUIDANCE HAD BEEN HINTING AT RAINFALL REACHING THE CWA LATE
THIS AFTERNOON FROM THE SOUTHWEST AHEAD OF THE MAIN THUNDERSTORMS
CURRENTLY IN LA. CURRENTLY THERE IS NO INDICATION THAT AFTERNOON
STORMS WILL DEVELOP AND TRACK UP FROM THE SOUTH. AT THIS
POINT...BEST CHANCE FOR THUNDERSTORMS WILL BE LATER THIS EVENING AS
THE SURFACE LOW OVER THE LOWER MISS VALLEY CONTINUES TO MOVE
NORTHEASTWARD. WILL MAINTAIN CATEGORICAL POPS FOR THE CWA THIS
EVENING AND OVERNIGHT. POSSIBILITY OF SEVERE WEATHER APPEARS
MARGINAL AT THIS POINT AS INSTABILITIES HAVE NOT BEEN IMPRESSIVE.
SINCE THE STORMS ARE STILL QUITE FAR AWAY AT THIS TIME...WILL HAVE
TO PLAY THE WAITING GAME.

RAINFALL WILL TAPER OFF SATURDAY MORNING FROM SOUTHWEST TO NORTHEAST
AS THE FRONT MOVES OFFSHORE. A COOLING AND DRYING TREND WILL THEN
BEGIN SATURDAY...AS HIGH PRESSURE BUILDS IN FROM THE GULF OF MEXICO.
COLD ADVECTION PERSISTENT THROUGH SATURDAY NIGHT AS SEEN IN 850 MB
WINDS AND ISOTHERMS. WITH THE STRONG COLD ADVECTION...AS WELL AS A
IMPRESSIVE UPPER LEVEL JET...WINDS WILL INCREASE TO NEAR WIND
ADVISORY CRITERIA SATURDAY AFTERNOON. AT THIS POINT HAVE FORECASTED
WINDS BETWEEN 15 AND 20 KT...AND SO HESITANT TO ISSUE A WIND
ADVISORY FOR SECOND PERIOD. WILL ALLOW SUBSEQUENT SHIFTS TO ASSESS
FURTHER MODEL RUNS.
&&

.LONG TERM /SUN THRU FRI/...EAST COAST TROUGHINESS MUCH OF THE LONG
TERM SPELLS MORE SEASONABLE TEMPS. HIGH PRES IN CONTROL SUN INTO MON
BEFORE A LOW PRES SYSTEM APPROACHES FROM THE W AND MOVES QUICKLY OFF
THE COAST TUE MORNING. WILL KEEP 20-30 POPS GOING FOR NOW AS SYSTEM
WILL HAVE LIMITED MOISTURE TO WORK WITH. COLDER AIR FILTERING IN ON
THE BACK SIDE OF THE LOW EARLY TUE MORNING BUT DO NOT XPCT ANY
PRECIP TYPE ISSUES ATTM AS H85 TEMPS ARE PROGGED TO BE AOA FREEZING.
DRY WX TUE-THU WITH COOL MORNINGS AND NEAR NORMAL HIGHS AROUND 60.
12Z GFS SHOWING ANOTHER SYSTEM FOR FRI BUT WITH SUCH A PROGRESSIVE
PATTERN...TIMING OF FEATURES IS RATHER DIFFICULT TO PIN DOWN.
THUS...PREFER TO KEEP THINGS DRY THRU FRI AS WELL.
&&

.MARINE...CURRENT SEAS IN THE OUTER GA WATERS HAVE DROPPED TO 4
FT...HOWEVER WILL ALLOW SCA FOR AMZ374 TO CONTINUE IN ACCOUNT OF
INCREASING TREND IN SEAS THROUGH THE EVENING.

STRONG WIND REGIME WILL PEAK SATURDAY AFTERNOON...AS A
STRONG UPPER LEVEL JET AND VIGOROUS COLD ADVECTION INITIATES
FOLLOWING THE COLD FRONTAL PASSAGE. THE CORE OF A 170 KT JET AT 250
MB WILL BE LOCATED DIRECTLY OVER SC AND GA SATURDAY
AFTERNOON...ALONG WITH A 700 MB JET WITH 52 KT WINDS. WITH A
SUFFICIENT MIXING PROFILE DURING COLD ADVECTION...IT SEEMS QUITE
LIKELY THAT HIGHER WIND SPEEDS WILL REACH SURFACE LEVEL. WINDS ON
SATURDAY WILL BE AN ISSUE OVER THE MARINE ZONES AND BELIEVE FREQUENT
GALE FORCE GUSTS ARE POSSIBLE. AT THIS TIME WILL WAIT TO ISSUE GALE
WARNING AND INSTEAD ALLOW SCA TO COVER INCREASING WINDS OVER THE
MARINE ZONES BEGINNING TONIGHT AND INTO SATURDAY.

IMPROVING MARINE CONDITIONS SUN AS CAA CUTS OFF BEFORE A LOW PRES
SYSTEM APPROACHES MON WITH A COLD FRONT CROSSING THE WATERS MON
NIGHT. LGT TO MODERATE OFFSHORE FLOW PREVAILS POST FROPA THRU WED
WITH WINDS/SEAS REMAINING AOB SCA CRITERIA...XCPT POSSIBLY OVER THE
OUTER GA WATERS TUE WHERE WINDS COULD EXCEED 20 KT AND/OR SEAS COULD
BUILD TO 6 FT FOR A BRIEF PERIOD OF TIME.
&&

.AVIATION...LOW CLOUDINESS IS HANGING TOUGH THIS AFTERNOON AT BOTH
TERMINALS...DESPITE PARTIAL CLEARING JUST TO THE NORTH. AS THE LOW
DEVELOPS TO THE WEST...EXPECT A LOW LEVEL SOUTHEASTERLY FLOW TO
DEVELOP WHICH WILL ACT TO KEEP THE CLOUDS IN PLACE. THUS...HAVE
AMENDED TO KEEP MVFR CIGS IN PLACE THROUGH AROUND SUNSET.

EXPECT A ROUND OF SHOWERS AND THUNDERSTORMS AT BOTH TERMINALS
GENERALLY BETWEEN 01Z AND 05Z SATURDAY.
&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.

         SMALL CRAFT ADVISORY AMZ350-352 BEGINNING 1 AM SAT.
