AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
421 PM EDT SAT MAR 29 2014

.SYNOPSIS...
A POTENT STORM SYSTEM WILL TRACK EAST ACROSS THE REGION TONIGHT
THROUGH SUNDAY AFTERNOON. HIGH PRESSURE WILL BUILD INTO THE
CAROLINAS FROM THE WEST LATE SUNDAY THROUGH EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 300 PM SATURDAY...

OVERVIEW: AN AMPLIFYING UPPER LEVEL WAVE IN THE TN VALLEY AT 17Z
WILL PROGRESS INTO THE MID-ATLANTIC THIS EVENING/TONIGHT...WITH
A DEEPENING SFC LOW (CENTERED IN SOUTHWEST VA AT 17Z) TRACKING
NORTHEAST TOWARD THE DELMARVA.

PRECIPITATION CHANCES:
A NW-SE ORIENTED BAND OF SHOWER ACTIVITY EXTENDED FROM GOLDSBORO-
RALEIGH-DANVILLE AT 18Z...IN ASSOCIATION WITH LOW-LEVEL WARM
ADVECTION AND VERY WEAK ELEVATED INSTABILITY. THIS ACTIVITY WILL
CONTINUE TO SHIFT NORTH OF CENTRAL NC IN CONCERT WITH LOW-LEVEL
WARM ADVECTION. EXPECT LITTLE CHANCE FOR SHOWER ACTIVITY OVER THE
NEXT FEW HRS GIVEN WANING LOW-LEVEL WARM ADVECTION AND THE MID-
LEVEL DRY SLOT RAPIDLY ADVANCING NE INTO THE REGION. HOWEVER...
CHANCES FOR CONVECTION WILL INCREASE ACROSS THE W/SW PIEDMONT BY
~21Z AS STRONG DPVA/HEIGHT FALLS IMPINGE UPON WESTERN PORTIONS OF
THE STATE IN ADVANCE OF THE AMPLIFYING UPPER LEVEL WAVE...LOW-
LEVEL CONVERGENCE INCREASES AT THE LEADING EDGE OF SW FLOW
ADVECTING A DRIER LOW-LEVEL AIRMASS FROM GA INTO SC/NC...AND
GRADUAL DIURNAL DESTABILIZATION ASSOC/W A MOIST BOUNDARY LAYER
(CHARACTERIZED BY SURFACE DEWPOINTS OF 60-65F AND 925 MB DPTS OF
13-14C) AND SOME BREAKS OR THINNING OF CLOUD COVER (PER 18Z VIS
SAT IN UPSTATE SC). CHANCES FOR CONVECTION (INCLUDING ISOLD
STORMS) SHOULD INCREASE AND EXPAND EASTWARD BETWEEN 21-03Z AS
FURTHER DESTABILIZATION OCCURS FROM WEST-EAST IN ASSOC/W THE
LAYER-LIFTING OF A CONVECTIVELY UNSTABLE AIRMASS (THETA-E
DECREASING W/HEIGHT). SHOWER ACTIVITY MAY PERSIST THROUGH 12Z SUN
(ESP NORTH OF HWY 64) WHERE BOUNDARY LAYER MOISTURE WILL LINGER
THE LONGEST IN VICINITY OF STRONG DPVA ATTENDANT THE AMPLIFYING
UPPER LEVEL WAVE.

TEMPERATURES: A WEAK THERMAL/MOISTURE BOUNDARY WAS PRESENT OVER
THE NW PIEDMONT WHERE TEMPS AND DEWPOINTS WERE A GOOD 5F COOLER
THAN OBSERVATIONS SOUTH OF HWY 64. A THERMAL/MOISTURE BOUNDARY MAY
PERSIST INTO THIS EVENING FROM CLT-BUY-DAN AS SOUTHERLY FLOW AND
THINNING CLOUD COVER ALLOW TEMPS TO RISE INTO THE LOWER TO PERHAPS
MID 70S IN THE SOUTH. EXPECT HIGHS RANGING FROM THE LOWER/MID 60S
NW PIEDMONT TO LOWER 70S...PERHAPS MID 70S NEAR THE SC BORDER.
LOWS TONIGHT WILL DEPEND ENTIRELY ON COLD ADVECTION...WITH TEMPS
RAPIDLY FALLING FROM W-E OR SW-NE IN ASSOC/W A COLD FRONT SWEEPING
THROUGH CENTRAL NC.

SEVERE THREAT:
DEEP-LAYER SHEAR WILL BE MORE THAN ADEQUATE FOR ROTATING UPDRAFTS
/SUPERCELLS/ THIS AFTERNOON AND EVENING WITH 0-6KM SHEAR VALUES OF
40-50 KT. LOCALLY ENHANCED 0-1KM SHEAR WILL STILL BE POSSIBLE...
PRIMARILY FROM THE TRIANGLE INTO THE NORTHERN PIEDMONT WHERE A
STRONGER ISALLOBARIC COMPONENT TO SFC-925 MB FLOW WILL ALLOW
BACKED LOW-LEVEL FLOW TO PERSIST LONGER. OVERALL...FORECAST
SOUNDINGS SHOW LESS LOW-LEVEL SHEAR THAN INDICATED BY PRIOR MODEL
GUIDANCE AS FLOW VEERS TO THE SW LATE THIS AFT/EVE (ALREADY
OCCURRING UPSTREAM IN SC). DESTABILIZATION HAS BEGUN AS OF MID
AFTERNOON AND WILL LIKELY PERSIST THROUGH THIS EVENING IN ASSOC/W
BREAKS IN CLOUD COVER AT THE TAIL END OF PEAK HEATING...AND
MORE SUBTLY VIA LAYER-LIFTING OF A CONVECTIVELY UNSTABLE
ATMOSPHERE IN PLACE OVER CENTRAL NC. EXPECT ANALYZED MLCAPE
VALUES OF 250-500 J/KG NORTH TO 500-1000 J/KG NEAR THE SC BORDER.
UNCERTAINTY PERSISTS W/REGARD TO WHETHER OR NOT INGREDIENTS WILL
BE IN SUFFICIENT JUXTAPOSITION FOR DEEP CONVECTION TO DEVELOP
THIS EVENING...AND AT THIS POINT AN ISOLD SEVERE THREAT SEEMS
MORE CONDITIONAL THAN PREVIOUSLY INDICATED...THOUGH SUCH A
DETERMINATION MAY BE PREMATURE GIVEN THAT THE BEST
DESTABILIZATION AND FORCING WILL BE IN THE 21-03Z TIME FRAME. IF
DEEP CONVECTION DEVELOPS...ROTATING UPDRAFTS CAPABLE OF PRODUCING
DAMAGING WINDS AND MARGINALLY SEVERE HAIL WILL BE POSSIBLE. AN
ISOLD TORNADO ALSO REMAINS POSSIBLE...PRIMARILY IF A DISCRETE CELL
EXHIBITS DEVIANT MOTION IN VICINITY OF LOCALLY ENHANCED 0-1 KM SRH
ALONG AND NORTH OF HWY 64 BETWEEN 21-03Z. -VINCENT

&&

.SHORT TERM /SUNDAY AND SUNDAY NIGHT/...
AS OF 300 PM SATURDAY...

THE UPPER LOW WILL ASSUME A NEGATIVE TILT AS IT PIVOTS SLOWLY
NORTHEASTWARD ACROSS NC AND VIRGINIA DURING THE DAY ON
SUNDAY...MOVING OFF THE DELMARVA COAST SUNDAY EVENING/NIGHT.
SOUNDINGS SHOW STRONG COOLING/MOISTENING ALOFT AS THE COLD CORE LOW
MOVES THROUGH THE AREA...WITH TEMPERATURES STRUGGLING TOO WARM
DURING THE DAY WITH OVERCAST LOW CLOUDS AND RENEWED PRECIP WITHIN A
WRAP AROUND PRECIP BAND. HAVE LOWERED FORECAST HIGHS QUITE A
BIT...ESPECIALLY ACROSS THE NORTH WHERE HIGHER POPS/QPF IS EXPECTED.
HIGHS RANGING FROM NEAR 50 NE TO MID/UPPER 50S ACROSS THE
SOUTH/SOUTHWEST...AND EVEN THAT COULD BE TOO WARM IF SOME OF THE
WETTER SOLUTIONS VERIFY. DEEPENING SURFACE EXITING THE TIDEWATER
COAST SHOULD RESULT IN BREEZY CONDITIONS WITH SUSTAINED NWLY WINDS
15-20KTS...GUSTING TO 30KTS...REMAINING BELOW ADVISORY CRITERIA.
PRECIP WILL TAPER OFF AND MOISTURE WILL CLEAR OUT FROM SW TO NE
DURING THE EVENING AS THE UPPER LOW SHIFTS OFFSHORE. LOWS IN THE
LOWER TO MID 30S NW TO MID/UPPER 30S SE WITH A STEADY 7-10KT BREEZE
PREVENTING WIDESPREAD FROST. -CBL

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
AS OF 300 PM SATURDAY...

TEMPERATURES WILL QUICKLY MODIFY MONDAY WITH STRONG SYNOPTIC SCALE
SUBSIDENCE AS S/W RIDGING DEVELOPS ACROSS THE SOUTHEAST AND REMAINS
OVER THE AREA THROUGH LATE IN THE WORK WEEK. THIS WILL KEEP THE
PRIMARY STORM TRACK WELL NORTH OF THE AREA...THROUGH THE MIDWEST AND
GREAT LAKES REGION. THIS WILL SUPPORT DRY CONDITIONS THROUGH
THURSDAY. AFTER SEASONABLE HIGHS OF UPPER 60S/LOWER 70S ON MONDAY...
EXPECT ABOVE NORMAL TEMPERATURES OF 75-80 WED/THURS.

NEXT WEATHER SYSTEM COULD IMPACT THE AREA LATE FRIDAY AND INTO
SATURDAY WITH CURRENT MODEL PROJECTION SHOWING A WEAKENING BAND OF
CONVECTION ACROSS THE SOUTHEAST...AS IT BECOMES WELL REMOVED FROM
THE ATTENDANT S/W TROUGH LIFTING NEWD THROUGH THE GREAT LAKES.
IMPACTS/SEVERE THREAT APPEAR MINIMAL AT THIS TIME. -CBL

&&

.AVIATION /19Z SATURDAY THROUGH THURSDAY/...
AS OF 130 PM SATURDAY...

24-HR TAF PERIOD:
WIDESPREAD IFR CONDITIONS (CEILINGS 500-1000 FT AGL) AT 18Z WILL
IMPROVE TO MVFR (CEILINGS 1000-2000 FT AGL) IN MANY LOCATIONS
LATE THIS AFTERNOON (18-00Z) IN ASSOC/W DIURNAL HEATING AND A
WARMER AIRMASS ADVECTING INTO THE REGION FROM THE SOUTHWEST.
EXPECT AN INCREASING CHANCE FOR SHOWERS AND ISOLD THUNDERSTORMS
THIS AFTERNOON/EVENING AS AN AMPLIFYING UPPER LEVEL TROUGH
APPROACHES FROM THE WEST...ESPECIALLY BETWEEN 21-03Z. AN ISOLD
SEVERE STORM CAPABLE OF PRODUCING DAMAGING WINDS CANNOT BE RULED
OUT. SOUTHEAST WINDS AT 5-10 KT AT 18Z WILL GRADUALLY BECOME
SOUTH/SSW THIS AFT/EVE...THEN RAPIDLY STRENGTHEN AND VEER TO THE
WEST/WNW AT 13-17 KT WITH GUSTS UP TO 25 KT IN THE WAKE OF A COLD
FRONT MOVING EAST THROUGH CENTRAL NC BETWEEN ROUGHLY 03-07Z.
IFR/MVFR CONDITIONS ARE EXPECTED TO IMPROVE TO HIGH-END MVFR AND
EVENTUALLY VFR IN THE WAKE OF THE COLD FRONT AFTER MIDNIGHT
TONIGHT. GUSTY NORTHWEST WINDS ARE EXPECTED TO PERSIST ON SUNDAY
AS THE AFOREMENTIONED SYSTEM FURTHER AMPLIFIES ALONG THE MID-
ATLANTIC COAST.

LOOKING AHEAD:
VFR CONDITIONS WILL PREVAIL LATE SUNDAY THROUGH MID TO LATE WEEK
IN ASSOC/W A DRY PATTERN. -VINCENT
