AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
330 PM EDT TUE MAY 24 2005

.SHORT TERM (TONIGHT THROUGH WEDNESDAY NIGHT)...
UPPER LOW REMAINS IN PLACE OVER SOUTHERN PA/NORTHERN VA WITH SPOKES
ROTATING AROUND IT. STORMS STARTING TO POP UP ON RADAR BUT OVERALL
COVERAGE SHOULD REMAIN AROUND 20 PERCENT ACROSS SC AND 30 PERCENT
ACROSS NC. BEST ACTIVITY STILL LOOKS AS IF IT WILL REMAIN NORTH OF
THE AREA.

ANOTHER VORT CURRENTLY MOVING ACROSS NORTHWEST PA WILL PASS JUST
NORTH OF THE CWA LATE TONIGHT. WHILE THE SECOND SHORT WAVE LOOKS
WEAKER IT STILL MAY FIRE A FEW STORMS. KEEPING 30 POPS NORTH WITH
20S SOUTH TONIGHT.

UPPER LOW DRIFTS A LITTLE FURTHER NORTH WEDNESDAY AND WEDNESDAY
NIGHT WITH BEST MOISTURE AND DYNAMICS FURTHER NORTH AS WELL. KEEPING
20 POPS CWA WIDE ON WEDNESDAY BECAUSE UPPER LOW AND ITS ASSOCIATED
COLD POOL WILL STILL BE CLOSE ENOUGH THAT AN ISOLATED SHOWER OR
THUNDERSTORM CANNOT BE RULED OUT. HIGHS WEDNESDAY WILL BE AROUND 10
DEGREES BELOW NORMAL. TEMPERATURES COULD BE UP TO 15 DEGREES BELOW
NORMAL IF UPPER LOW IS DRAGGED FURTHER SOUTH BY SHORT WAVES THAN
GUIDANCE IS ANTICIPATING.

&&

.LONG TERM (THURSDAY THROUGH TUESDAY)...
HEIGHTS INCREASE THURSDAY AS UPPER LOW/TROF MOVES NORTHEAST.
TEMPERATURES WILL STILL BE BELOW NORMAL...BUT ONLY BY A FEW DEGREES.
NO POPS THURSDAY THROUGH FRIDAY WITH DRY AIR MASS AND ZONAL FLOW IN
THE WAKE OF THE UPPER SYSTEM.

COLD FRONT APPROACHES FROM THE NORTHWEST FRIDAY...BUT TIMING OF
FROPA IS IN QUESTION. LATEST GFS/CANADIAN/ECMWF TIME FROPA AROUND
12Z SATURDAY WHILE THE NAM IS ABOUT 12 HOURS FASTER. FAVOR THE GFS
FRONT STALLS OFF THE COAST SATURDAY NIGHT THROUGH MONDAY...BUT HOW
FAR FROM THE ILM CWA? BROAD UPPER TROF AND SURFACE HIGH MOVING IN
FROM THE NORTHWEST SHOULD KEEP THE BOUNDARY STALLED FAR ENOUGH SOUTH
THAT THERE WILL BE LITTLE TO NO IMPACT ON THE AREA.

FRONT RETURNS NORTH AS A WARM FRONT TUESDAY ONCE UPPER TROF AND
SURFACE HIGH SHIFT OFF THE COAST. KEEPING SILENT POPS FRIDAY NIGHT
THROUGH TUESDAY DUE TO LARGE AMOUNT OF UNCERTAINTY IN THE EXTENDED
FORECAST.

&&

.AVIATION...
ALL TERMINALS INITIALIZE WITH VFR CONDITIONS THIS
AFTERNOON AS H500 VORT MAX IS POISED TO ROTATE THROUGH THE AREA
LATER WITH IMPLICATIONS FOR AVIATION CONCERNS.

STRONG DYNAMICS WITH LIMITED MOISTURE WARRANTS AN INCLUSION FOR TSRA
FOR ALL COASTAL TERMINALS FOR THE LATE AFTERNOON...EARLY EVENING
TIME FRAME IN COASTAL TERMINALS. FLO SHOULD BE FAR ENOUGH DISPLACED
FROM THE DYNAMICS TO PRECLUDE THUNDERSTORM ACTIVITY. HAVE ONLY
DROPPED FLIGHT CATEGORIES TO MVFR CONSIDERING THE RELATIVELY DRY
LOWER LEVELS.

COLD ADVECTION ENSUES OVERNIGHT IN THE WAKE OF THE SHORTWAVE AS A
STRATUS DECK IS EXPECTED TO DEVELOP. MAV GUIDANCE DROPPING CIGS TO
IFR LEVELS EARLY WEDNESDAY IN COASTAL TERMINALS. WILL NOT BE SO
PESSIMISTIC AND MAINTAIN MVFR CIGS.

LOW LEVEL MOISTURE MIXES OUT QUICKLY WEDNESDAY MORNING...ALLOWING
VFR CONDITIONS TO RETURN.

&&

.MARINE...
OUT OF THE ORDINARY...RETROGRESSION OF UPPER NORTHEAST LOW THIS
AFTERNOON INTO EARLY WEDNESDAY. POTENT UPPER S/W TROF ROTATING
AROUND UPPER LOW TO PASS THRU THE FA THIS EVENING...PUSHING SFC
BOUNDARY WELL SOUTH AND EAST OF THE AREA BY SUNRISE WEDNESDAY. THIS
WILL RESULT IN A TIGHT SFC PG COMBINED WITH CAA TO PRODUCE A DECENT
SURGE OF NW-N WINDS...MAINLY BETWEEN 06Z AND 16Z WED. THE WATERS
FROM CAPE FEAR NORTHWARD HAVE THE BEST POTENTIAL TO SEE SMALL CRAFT
ADVISORY CONDITIONS. SCEC WILL LIKELY BE REALIZED IN THE OTHER ZONES
AND WILL BE UPDATED WHEN WARRANTED. WILL ALSO PLACE GUSTY WINDS BUT
ONLY HIGHLIGHT THEM AS...FEW. UPPER LOW TO SLOWLY LIFT NE
THU...LOSING ITS SFC CYCLONIC GRIP ACROSS THE REGION BY FRIDAY. WEAK
S/W RIDGE TAKES HOLD FOR FRIDAY INTO SATURDAY BEFORE LONGWAVE TROF
RESUMES ITS PLACE ACROSS THE REGION. LATE WEEKEND APPROACH OF SLOW
MOVING 5H S/W TROF IN THE SOUTHERN STREAM SOMEWHAT SUSPECT...AND
HAVE NOT ENTIRELY BOUGHT THIS SOLUTION AS OF YET.

&&

.ILM WATCHES/WARNINGS/ADVISORIES...
NC...NONE.
SC...NONE.
