AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
341 PM EST TUE FEB 26 2013

.SYNOPSIS...
A POTENT UPPER LEVEL LOW AND ATTENDANT SURFACE LOW WILL TRACK
NORTHEAST INTO THE OHIO VALLEY THIS AFTERNOON...WHILE A SECONDARY
LOW PRESSURE SYSTEM TRACKS NORTHEAST ALONG THE CAROLINA COAST. AN
ASSOCIATED COLD FRONT WILL CROSS CENTRAL NORTH CAROLINA LATE
TONIGHT AND WEDNESDAY MORNING AS THE SECONDARY LOW TRACKS
NORTHEAST ALONG THE MID ATLANTIC COAST.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 330 PM TUESDAY...

OVERVIEW:
A POTENT VERTICALLY STACKED LOW OVER MO/IL AT 19Z WILL TRACK
NORTHEAST INTO THE OH VALLEY THROUGH TONIGHT...WHILE A SECONDARY LOW
WHICH HAS RECENTLY DEVELOPED UPSTREAM OVER GA/SC TRACKS NORTHEAST
THROUGH EASTERN NC THIS EVENING...AND ALONG THE MID-ATLANTIC COAST
TONIGHT.

REST OF TODAY:
WIDESPREAD MODERATE RAIN AIDED BY A 50-60 KT SOUTHEASTERLY LLJ OFF
THE ATLANTIC HAS STEADILY WANED FROM SW-NE ACROSS CENTRAL NC THIS
AFTERNOON AS LOW-LEVEL FLOW VEERS TO THE SOUTHWEST...CUTTING OFF THE
ATLANTIC MOISTURE FEED AND ENDING STRONG LOW-LEVEL WARM ADVECTION/
ISENTROPIC LIFT. SFC ANALYSIS INDICATED A SECONDARY SFC LOW OVER
SOUTHERN SC AT 20Z...WITH A NARROW WARM SECTOR IN FAR NORTHEAST SC
AND FAR SOUTHEAST NC. ALTHOUGH LITTLE IF ANY DEVELOPMENT HAS
OCCURRED UPSTREAM IN THE WARM SECTOR...ELEVATED SHOWER ACTIVITY HAS
DEVELOPED OVER WESTERN PORTIONS OF THE CAROLINAS IN THE PAST FEW
HOURS IN ASSOC/W A COLD FRONT ALOFT...AND AT THE LEADING EDGE OF
SLIGHTLY STEEPER MID-LEVEL LAPSE RATES WHERE MARGINAL MUCAPE IS
PRESENT PER LATEST SPC MESOANALYSIS. IF THE COLD FRONT ALOFT AND
SLIGHTLY STEEPER MID-LEVEL LAPSE RATES PROGRESS INTO EASTERN
PORTIONS OF THE STATE AT THE RIGHT TIME...I.E. COINCIDENT WITH THE
BRIEF/NARROW WARM SECTOR SPREADING NORTHEAST FROM FLORENCE SC INTO
EASTERN NC...IT IS POSSIBLE THAT SOME RENEWED CONVECTIVE DEVELOPMENT
COULD OCCUR BETWEEN 21-00Z. IF THAT IS THE CASE...AND IF ANY ROBUST
UPDRAFTS CAN DEVELOP...THEN AN ISOLD SEVERE STORM COULD NOT BE RULED
OUT GIVEN THE MAGNITUDE OF DEEP LAYER SHEAR. LOW-LEVEL SHEAR
PROFILES ARE BECOMING INCREASINGLY UNIDIRECTIONAL THIS AFT/EVE...
STRAIGHTENING HODOGRAPHS IN THE LOWEST 1 KM AND REDUCING THE
POTENTIAL FOR LOW-LEVEL ROTATION W/ANY ROBUST CONVECTION (IF ANY
DEVELOPS). ALTHOUGH LOCALLY ENHANCED 0-1 SRH CAN BE EXPECTED IN
VICINITY OF THE BAROCLINIC ZONE AND IN ADVANCE OF THE SFC LOW WHERE
BACKED SFC FLOW WILL BE PRESENT...THE AREA THIS WOULD OCCUR (AND
POTENTIALLY COINCIDE WITH THE COLD FRONT ALOFT) WOULD MOST LIKELY BE
EAST OF THE WFO RAH CWA. WITH THE ABOVE IN MIND...WILL INDICATE
PRECIP CHANCES ENDING FROM SW-NE IN NORTHEAST COASTAL PLAIN AND
NORTHERN PIEDMONT BY 23Z...WITH A SLIGHT CHANCE OF SHOWERS OR AN
ISOLD STORM IN THE SOUTHEAST COASTAL PLAIN.

TONIGHT:
EXPECT DRY CONDITIONS OVERNIGHT IN THE WAKE OF THE CFA...ASIDE
PERHAPS FROM DRIZZLE IN THE LINGERING COLD AIR DAMMING WEDGE.
CHALLENGING TEMPERATURE FORECAST. TEMPS ARE EXPECTED TO RANGE FROM
THE UPPER 30S AT INT/GSO TO LOWER/MID 50S ALONG THE HWY 1 CORRIDOR
TO THE MID 60S IN THE FAR SE COASTAL PLAIN THIS AFT. AS THE
AFOREMENTIONED SFC LOW PROGRESSES THROUGH EASTERN NC...LOW-LEVEL
FLOW WILL BACK TO THE N/NW AND SHOULD ALLOW THE WEDGE TO ADVECT BACK
EAST THIS EVENING...WITH TEMPS FALLING FROM WEST-EAST OVERNIGHT. THE
PRIMARY FCST PROBLEM WILL BE ASSOC/W A TIGHTENING PRESSURE GRADIENT
AND IMPETUS FOR SOUTHWEST SFC FLOW OVERNIGHT...WHICH COULD
POTENTIALLY ADVECT A DRIER UPSTREAM AIRMASS INTO PORTIONS OF CENTRAL
NC AND HELP ERODE THE WEDGE BETWEEN MIDNIGHT-SUNRISE. EXPECT THAT
THE CAD WEDGE AND ASSOCIATED MESO-HIGH WILL DELAY THE TIGHTENING
PRESSURE GRADIENT AND ALLOW THE WEDGE TO HOLD IN MOST LOCATIONS.
GIVEN CLEARING ALOFT IN THE PRESENCE OF A SATURATED SFC AIRMASS...
EXPECT A POTENTIAL FOR WIDESPREAD DENSE FOG OVERNIGHT... UNLESS THE
AFOREMENTIONED SOUTHWEST BREEZE DEVELOPS AND ADVECTS A DRIER AIRMASS
INTO THE AREA. WILL INDICATE LOWS RANGING FROM THE MID/UPPER 30S FAR
NW TO MID/UPPER 40S FAR SE. -VINCENT

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
AS OF 1245 PM TUESDAY...

DRY AND MILD WSW FLOW IS EXPECTED TO BRING PARTLY TO MOSTLY SUNNY
SKIES ACROSS OUR REGION WEDNESDAY. BREEZY CONDITIONS WITH SW WINDS
10-20 MPH WITH GUSTS TO 25 MPH. HIGHS 60-65 EXCEPT UPPER 50S NW.

WEDNESDAY NIGHT AND THURSDAY... EXPECT THE MEAN FLOW TO BECOME MORE
WESTERLY TO NORTHWESTERLY... AND INCREASE ESPECIALLY THURSDAY. THIS
WILL BRING PROGRESSIVELY COOLER TEMPS TO OUR REGION. AN UPPER LEVEL
DISTURBANCE SHOULD BRING AN INCREASE IN CLOUDINESS WEDNESDAY
NIGHT...THEN DECREASING CLOUDINESS THURSDAY AS STRONG DAA/CAA ARRIVE
FROM THE NW. A MOISTURE STARVED COLD FRONT IS EXPECTED TO PUSH
THROUGH OUR REGION OVERNIGHT... WITH ONLY A FEW SPRINKLES EXPECTED.

VARIABLY CLOUDY SKIES WEDNESDAY NIGHT WITH WESTERLY WINDS 5-15 MPH.
LOWS 35-40. VARIABLY CLOUDY BECOMING PARTLY TO MOSTLY SUNNY THURSDAY
AFTERNOON. WINDY AND CHILLIER. NW WINDS 15-25 MPH WITH GUSTS TO
30-35 MPH. HIGHS 50-60 NW TO SE. MOSTLY CLEAR AND CHILLY THURSDAY
NIGHT. LOWS 30-35.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
AS OF 1245 PM TUESDAY...

COLDER... AND WATCHING WINTER WEATHER POTENTIAL THIS WEEKEND THROUGH
NEXT WEEK.

WE CONTINUE TO PREFER THE EUROPEAN GUIDANCE PER HPC VERIFICATION OF
THE MID/UPPER FLOW PATTERN EXPECTED THIS WEEKEND INTO NEXT WEEK. THE
LOCAL SPECIFIC DETAILS SUCH AS HONING IN ON EXACTLY THE
STRENGTH/POSITION/TIMING OF POTENTIAL SYSTEMS THAT DIRECTLY AFFECT
OUR REGION REMAINS PROBLEMATIC.

THE GENERAL PATTERN FOR OUR REGION WILL BE FOR PROGRESSIVELY COLDER
TEMPERATURES AND THE POTENTIAL FOR A COUPLE OF SYSTEMS (EITHER
NUISANCE OR OTHERWISE)... ONE THIS WEEKEND... AND ANOTHER NEXT TUE
NIGHT OR WED. THE LATTER OF THE TWO LOOK MORE PROBLEMATIC... WITH
THE CURRENT TRACK/STRENGTH ADVERTISED BY THE LAST 2-3 RUNS OF THE
OPERATIONAL EUROPEAN SUPPORTIVE OF A WINTER STORM POTENTIAL. THIS
IS ESPECIALLY TRUE GIVEN THE EXPECTED DRY COLD AIR IN PLACE BEFORE
THE SYSTEM COURTESY OF COLD SURFACE HIGH PRESSURE LOCATED IN A
FAVORABLE POSITION AND OF FORECAST FAVORABLE STRENGTH TO DELIVER
CAA/DAA INTO OUR PIEDMONT DAMMING REGION... ALTHOUGH AGAIN
PROGRESSIVELY MOVES OFFSHORE AS THE FORECAST PRECIPITATION ARRIVES.
WE WILL NOT CARRY PRECIPITATION CHANCES NOW OUT DAYS 6-7 AS DETAILS
WITH ANY SYSTEM THIS FAR OUT CAN NOT BE IRONED OUT.

THE POSSIBLE WINTER TYPE SYSTEM THIS WEEKEND APPEARS TO BE LOOKING
MORE AND MORE INTERESTING BY THE MODEL RUN. THE LATEST GFS SUGGESTS
A MID/UPPER LEVEL "CUT OFF" LOW PRESSURE PROGRESSIVELY DIVING ESE
INTO THE TENNESSEE VALLEY AND SOUTHERN APPALACHIANS SAT-SUN... THEN
NE OVER NC SUNDAY AND SUNDAY NIGHT. WHILE THIS SOLUTION HAS SOME
SUPPORT FROM THE LATEST NAM AND EC... THOSE OPERATIONAL MODELS ARE
WEAKER AND NORTHWARD WITH THE PLACEMENT OF THE MID/UPPER LOW TRACK
CLOSER TO THE NC/VA BORDER... UNFAVORABLE SOLUTIONS FOR A
SIGNIFICANT WINTER EVENT. GIVEN THE CONTINUED UNCERTAINTY... WE LIKE
THE CURRENT LOW CHANCE POP FOR RAIN/SNOW SHOWERS AS CURRENTLY
ADVERTISED FOR SAT NIGHT AND SUNDAY... WITH AT LEAST TRENDS
SUGGESTING MORE IN THE WAY OF WINTERY WEATHER POTENTIAL FOR THIS
EVENT. MUCH MORE ON THIS POTENTIAL DURING THE COMING DAYS.

SENSIBLE WEATHER...

FRIDAY... PARTLY SUNNY WITH HIGHS 50-55.
SATURDAY... MOSTLY CLOUDY. A CHANCE OF SHOWERS. POSSIBLY SNOW
SHOWERS ESPECIALLY WEST AND NORTH. LOWS 28-33. HIGHS 38-48.
SUNDAY... A CHANCE OF RAIN OR SNOW SHOWERS... LOWS IN THE 30S. HIGHS
IN THE UPPER 30S AND 40S.
MONDAY... MOSTLY CLEAR. LOWS IN THE MID 20S. HIGHS 45-50.
TUESDAY... INCREASING CLOUDINESS. LOWS IN THE 20S. HIGHS IN THE 40S
TO LOWER 50S.

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
AS OF 100 PM TUESDAY...

24-HR TAF PERIOD:
EXPECT IFR/LIFR CONDITIONS TO PREVAIL AT ALL TERMINALS THIS AFT/EVE
INTO AT LEAST PORTIONS OF TONIGHT...IN ASSOC/W A COLD AIR DAMMING
WEDGE IN PLACE ACROSS CENTRAL NC. SOUTHEASTERLY LLWS WILL REMAIN IN
PLACE FOR SEVERAL MORE HOURS (THROUGH ~21Z)...BEFORE LOW-LEVEL WINDS
UNDERGO SOME WEAKENING AND VEER TO THE SOUTHWEST. A BRIEF
IMPROVEMENT TO MVFR WITH BREEZY SOUTHERLY WINDS AND A CHANCE FOR
SHOWERS/STORMS WILL BE POSSIBLE AT THE FAY TERMINAL BETWEEN 20-00Z.
OVERNIGHT...DRYING ALOFT IN THE PRESENCE OF A LINGERING COLD AIR
DAMMING WEDGE COULD RESULT IN WIDESPREAD DENSE FOG AND LIFR/VLIFR
CONDITIONS...THOUGH IT IS ALSO POSSIBLE THAT A TIGHTENING PRESSURE
GRADIENT OVER THE SOUTHEAST AND CAROLINAS WILL RESULT IN A
SOUTHWESTERLY BREEZE THAT WILL GRADUALLY ERODE THE COLD AIR DAMMING
WEDGE FROM SE-NE WITH IMPROVING CONDITIONS BETWEEN 06-12Z WED
MORNING. AT THIS TIME... PREFER TO ERR ON THE SIDE OF CAUTION AND GO
WITH A MORE CLIMATOLOGICAL FORECAST...INDICATING IFR/LIFR CONDITIONS
PERSISTING TONIGHT. REGARDLESS...EXPECT CONDITIONS TO IMPROVE
QUICKLY BETWEEN 12-16Z WED IN ASSOC/W BREEZY SOUTHWEST FLOW...WITH
VFR CONDITIONS RETURNING BY MID/LATE MORNING TO EARLY WED AFTERNOON.

LOOKING AHEAD:
EXPECT VFR CONDITIONS TO PREVAIL WEDNESDAY INTO THIS WEEKEND...
THOUGH PERIODIC MVFR CEILINGS AND SHOWER ACTIVITY CANNOT BE RULED
OUT...ESPECIALLY SAT NIGHT INTO SUN. -VINCENT
