Damaging Wind in South Carolina, May 30, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
220 PM EDT SUN MAY 30 2004

.DISCUSSION...
THE EASTERN PORTION OF THE FORECAST AREA IS IN THE WAKE OF THE LEAD
IMPULSE WHICH IS NOW OFF THE COAST AND THE WARM FRONT PER STREAM-
LINES CONTINUES TO DRIFT NORTH ACROSS NC. THE NEXT IMPULSE IS
MOVING INTO ILM/S WESTERN FORECAST AREA. DECENT CAPE IN PLACE
PER LAPS PLOTS ALONG WITH MODERATE INSTABILITY SO EXPECT SCATTERED
AREAS OF CONVECTION TO CONTINUE TO PROGRESS ACROSS THE FORECAST AREA
THROUGH THE AFTERNOON AND THIS EVENING. A COLD FRONT IS EXPECTED TO
MOVE INTO THE AREA DURING MON WITH DECENT SOUTHWEST FLOW AND WARMER
LOW LEVEL AIR PRECEDING IT. THIS WILL ALLOW TEMPS TO WARM TO THE
UPPER 80S TO AROUND 90 MOST LOCATIONS. 925 MB FLOW IS ALSO EXPECTED
TO RANGE FROM 25-30 KTS MONDAY RESULTING IN BREEZY SURFACE WINDS.
WILL CONTINUE WITH CHANCE POPS THROUGH MON...THEN SLIGHT CHANCE MON
NIGHT. WILL HOLD OFF ON POPS FOR TUE AND TUE NIGHT...AND CONTINUE
WITH CHANCE POPS FOR MAINLY WED AFTERNOON AND NIGHT AS THE NEXT COLD
FRONT MOVES INTO THE REGION. ALTHOUGH POPS MAY EVENTUALLY BE NEEDED
I LEFT THE END OF THE WEEK DRY (SILENT 10-20 POPS) FOR NOW GIVEN THE
INCONSISTENCIES SHOWN FROM RUN TO RUN. THE MODELS ARE STILL HAVING A
DIFFICULT TIME WITH FEEDBACK... ESPECIALLY THE GFS SO CONFIDENCE
REMAINS LOW AFTER THE FIRST FEW PERIODS. FAVORED A BLEND OF FWC/MAV
NUMBERS IN THE FIRST FEW PERIODS AND THE ENSEMBLE MEANS IN THE
EXTENDED.

&&

.MARINE...
SOUTH SOUTHEAST WINDS OF 10 TO 15 KNOTS AND SEAS OF 3 FT CONTINUE
WITH SURF CONDITIONS REPORTED AT 1 TO 2 FT AROUND 11 THIS MORNING.
AS FRONT APPROACHES WATERS MODELS SHOW INCREASE OF SOUTHWEST WINDS
IN THE 15 TO 25 KNOT RANGE.  09Z SREF ENSEMBLE PROBABILISTIC WINDS
SHOWING BEST PROBABILITY OF WINDS TO RANGE BETWEEN 20 TO 25 KNOTS
MONDAY AFTERNOON INTO MONDAY EVENING.

MRP GUIDANCE IS RUNNING IN THE 30 KNOT RANGE BUT WITH LATEST 12Z
MODELS AND ENSEMBLE PREFER THE 20 TO 25 KNOT RANGE. SO WILL CONTINUE
HEADLINE OF POSSIBLE SMALL CRAFT MONDAY AFTERNOON AND EVENING NORTH
OF LITTLE RIVER.  WAVEWATCH AT ILM01 SHOWING SEAS APPROACHING 6 FEET
FOR 4 HOURS MONDAY EVENING.

FOR THE REMAINDER OF THE FORECAST FOLLOWED GFS AND WAVE WATCH.

HORRY-MARION-MARLBORO-NEW HANOVER-PENDER-ROBESON-WILLIAMSBURG-
424 AM EDT SUN MAY 30 2004

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEASTERN NORTH CAROLINA
AND NORTHEASTERN SOUTH CAROLINA.

.DAY ONE...TODAY AND TONIGHT

NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.

HOWEVER...SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP AND MOVE
ALONG A FRONTAL BOUNDARY THAT IS SLOWLY LIFTING NORTH ACROSS THE AREA
TODAY. A FEW STORMS OR THE HEAVIER SHOWERS COULD CROSS THE SAME
LOCATIONS DUMPING COPIUS AMOUNTS OF RAINFALL EACH TIME IN A SHORT
PERIOD OF TIME. THIS COULD RESULT IN TEMPORARY PONDING OR FLOODING OF
LOW SPOTS AND SLOW DRAINING AREAS.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

THERE IS A SLIGHT RISK FOR SEVERE THUNDERSTORM ACTIVITY DURING THE
DAY ON MONDAY...MAINLY AHEAD OF A COLD FRONTAL BOUNDARY. AT THIS
POINT IN TIME...DAMAGING WIND GUSTS LOOK TO BE THE BIGGEST POTENTIAL.
HOWEVER AS THE SYSTEM EVOLVES DURING ITS MOVEMENT TOWARDS THE EAST
COAST...A TORNADO THREAT MAY BECOME A POSSIBILITY.

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY...HOWEVER ACTIVATION MAY
BE NEEDED ON MONDAY.
