Severe Thunderstorm Warning 217, NWS Raleigh, NC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
300 PM EDT THU SEP 10 2015

.SYNOPSIS...
A COLD FRONT WILL MOVE EAST THROUGH THE AREA
OVERNIGHT. A WEAK AREA OF LOW PRESSURE WILL DEVELOP OVER THE
CAROLINAS FRI AND FRI NIGHT...WHERE IT WILL LINGER UNTIL A STRONGER
COLD FRONT MOVES EAST ACROSS THE  REGION SAT AND SAT NIGHT.

&&

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

A VERY MOIST AND UNSTABLE ATMOSPHERE (18Z MESO ANALYSIS INDICATES
MODERATE INSTABILITY (3000 J/KG)OVER THE SANDHILLS AND COASTAL
PLAIN) COUPLED WITH THE APPROACH/PASSAGE OF A VORTICITY SHEAR AXIS
WILL TRIGGER SCATTERED CONVECTION ACROSS CENTRAL NC LATE THIS
AFTERNOON...PERSISTING THROUGH MOST OF THE EVENING HOURS.  DUE TO
THE HIGH MOISTURE CONTENT OF THE ATMOSPHERE...TORRENTIAL DOWNPOURS
WILL OCCUR WITH THE STRONGER STORMS. BULK OF WIND GUSTS WILL BE
BELOW 35KTS THOUGH AN ISOLATED DAMAGING WIND GUSTS CANNOT BE RULED
OUT. ANY PARTIAL CLEARING THAT OCCURS LATE THIS EVENING OR OVERNIGHT
WILL QUICKLY FILL IN WITH LOW CLOUDS AND PATCHY FOG. MIN TEMPS IN
THE UPPER 60S-LOWER 70S.

&&

.SHORT TERM /FRIDAY AND FRIDAY NIGHT/...
AS OF 300 PM THURSDAY...

FRIDAY...VORTICITY SHEAR AXIS LIFT E-NE AWAY FROM OUR REGION. THIS
FEATURE WILL LEAVE BEHIND A SURFACE TROUGH THAT SHOULD LIE ACROSS
SECTIONS OF OUR COASTAL PLAIN AND SANDHILLS. MOISTURE POOLING ALONG
THIS FEATURE AND AVAILABLE INSTABILITY SHOULD TRIGGER SCATTERED
CONVECTION BY MID-LATE AFTERNOON. BASED ON EXPECTED POSITION OF THE
SURFACE TROUGH...EXPECT HIGHEST THREAT FOR SCATTERED CONVECTION TO
OCCUR ROUGHLY ALONG AND EAST OF A WADESBORO-SANFORD-TARBORO LINE.
OVER MOST OF THE PIEDMONT...HARD TO DISCERN ANY FEATURE TO INITIATE
CONVECTION ASIDE FROM STRONG DIURNAL HEATING. THUS WILL MAINTAIN
SLIGHT CHANCE POPS OVER THIS REGION

MAX TEMPS FRIDAY DEPENDENT UPON WHEN LOW STRATUS LIFTS/DISSIPATE
OVER THE REGION. LATEST SREF GUIDANCE SUGGEST THAT LOW CLOUDS MAY
LINGER OVER THE EASTERN COUNTIES THROUGH MOST OF THE MORNING WHILE
PARTIAL SUN PROBABLE/LIKELY IN THE WEST PRIOR TO 15Z. CAVEAT...IF
WESTERN PIEDMONT RECEIVES WIDESPREAD RAINFALL LATE THIS
AFTERNOON/EVENING...THEN A SATURATED TOP SOIL MAY CAUSE LOW CLOUDS
TO PERSIST LONGER HERE AS WELL. BASED ON THE SOLUTION OF PARTIAL
SUNSHINE DELAYED IN THE EAST...EXPECT A FAIRLY UNIFORM TEMP FIELD IN
THE MID-UPPER 80S.

FRIDAY NIGHT...ISOLATED-SCATTERED CONVECTION SHOULD DIMINISH WITH
LOSS OF HEATING THOUGH A STRAY SHOWER POSSIBLE ALMOST ANYWHERE
OVERNIGHT. MIN TEMPS IN THE 65-70 DEGREE RANGE.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
AS OF 215 PM THURSDAY...

SAT/SAT NIGHT: STILL LOOKS LIKE THE BEST CHANCE FOR NUMEROUS SHOWERS
AND STORMS... PROMPTED BY THE PRESENCE OF THE OLD FRONTAL
ZONE/TROUGH THROUGH CENTRAL NC... AND THE APPROACHING SYNOPTIC COLD
FRONT EXPECTED TO MOVE THROUGH CENTRAL NC TO THE COASTAL PLAIN BY
SUN MORNING. A BAND OF MID LEVEL SHEARED VORTICITY WILL STREAM
NORTHEASTWARD FROM THE WRN GULF ACROSS THE FL PANHANDLE AND THROUGH
ERN NC SAT... PROVIDING DYNAMIC FORCING FOR ASCENT ABOVE THE BEST
LOW LEVEL MOISTURE... WHILE TO OUR WEST THE APPROACHING LONGWAVE
TROUGH WILL GENERATE 60-80 M HEIGHT FALLS AND MID LEVEL LAPSE RATES
APPROACHING 6.5 C/KM OVER THE REGION. WE SHOULD ALSO SEE STRONG
UPPER DIVERGENCE IN THE RIGHT ENTRANCE REGION OF THE SHARPENING
UPPER JET CORE... ADDING TO OVERALL ASCENT. THE 0-6 KM BULK SHEAR
WILL BE STRENGTHENING TO 40-50 KTS... WITH MARGINAL TO MODERATE
MUCAPE VALUES... AS MUCH AS 1000-1500 J/KG IN THE EASTERN CWA.
HOWEVER... MODELS SUGGEST A LACK OF GOOD LOW LEVEL MOISTURE
TRANSPORT OVER MUCH OF WRN/CENTRAL NC (CONFINED MOSTLY TO ERN NC)...
DUE IN LARGE PART TO A NOTABLE WESTERLY COMPONENT TO THE LOW LEVEL
WINDS AT 925/850 MB... AND MODELS SHOW JUST A NARROW BAND OF MODEST
700 MB MOISTURE MOVING THROUGH THE AREA LATE SAT AND PW VALUES
BARELY AT OR JUST ABOVE NORMAL IN THE EAST ONLY. SO THIS ALL MAY
SERVE TO LIMIT COVERAGE A BIT PARTICULARLY IN THE WEST... BUT A WELL-
MIXED BOUNDARY LAYER COULD AUGMENT THE RISK OF DAMAGING DOWNBURST
WINDS... AND THE INCREASED MID LEVEL FLOW ITSELF ORIENTED ROUGHLY
PARALLEL TO THE SURFACE FRONT SHOULD HEIGHTEN THE THREAT OF
ORGANIZED LINES AND BOWING SEGMENTS PROGRESSING QUICKLY ACROSS THE
CWA DURING THE AFTERNOON INTO EVENING. WILL ADJUST POPS TO HAVE
SLIGHT CHANCES IN THE MORNING... INCREASING IN COVERAGE TO NUMEROUS
NW TO SE THROUGH THE AFTERNOON INTO EARLY EVENING... BEFORE TRENDING
BACK DOWNWARD FROM WEST TO EAST OVERNIGHT AS THE FRONT AND DRIER AIR
GRADUALLY SWEEP THROUGH. WILL KEEP A SLIGHT CHANCE IN THROUGH THE
NIGHT HOWEVER WITH MODELS SHOWING LINGERING MOISTURE BELOW 8K FT AND
A BRIEF RESURGENCE OF UPPER DIVERGENCE AS SPEED MAXIMA ROTATE INTO
THE BASE OF THE UPPER TROUGH. THICKNESSES SUPPORT HIGHS FROM THE LOW
80S NW TO THE UPPER 80S SE. THICKNESSES DROP TO AROUND 15 M BELOW
NORMAL BY SUN MORNING... SUGGESTING LOWS FROM THE UPPER 50S NW TO
THE UPPER 60S SE... WHERE ANY BREAKS IN THE CLOUD COVER MAY NOT BE
SEEN UNTIL AFTER SUNRISE.

SUN/SUN NIGHT: A FEW SHOWERS MAY LINGER INTO THE MORNING HOURS SUN
ACROSS THE SE CWA... BUT AS THE SURFACE FRONT CONTINUES ITS EASTWARD
PROGRESSION... ALLOWING COOL SURFACE HIGH PRESSURE CENTERED OVER MO
TO BEGIN TO BUILD IN FROM THE WEST... RAIN CHANCES WILL BE ON THE
DECLINE AND SHOULD BE COMPLETELY GONE BEFORE NOON WITH THE ONSET OF
STRONG SUBSIDENCE AND THE ARRIVAL OF SUB-1.0 INCH PW. EXPECT FLAT CU
TO FILL IN BY AFTERNOON AS THE LONGWAVE TROUGH AXIS AND VORTICITY
MAX SWING THROUGH... BUT OTHERWISE CLOUD COVER SHOULD BE DECREASING.
EXPECT A SOMEWHAT BREEZY AND SEASONABLY COOL DAY... WITH THICKNESSES
SUPPORTING HIGHS OF 72-79. LOWS IN THE 50S WITH WINDS DYING OFF
AFTER SUNSET.

MON-THU: HIGH CONFIDENCE IN DRY WEATHER AND PLENTY OF SUNSHINE
DURING THIS PERIOD. THE SURFACE HIGH WILL SHIFT OVERHEAD THEN TO OUR
NORTHEAST THROUGH THE WEEK... SETTLING OVER NEW ENGLAND BY THU WHILE
EXTENDING DOWN THE EASTERN SEABOARD THROUGH CENTRAL NC. WE MAY SEE A
AN INCREASE IN CLOUDS AREAWIDE THU AFTERNOON ALONG WITH A FEW
SHALLOW SHOWERS IN THE EAST (ALONG/E OF I-95) WITH INCREASING
ATLANTIC-SOURCE NE FLOW. THE MID LEVEL TROUGH AXIS LIFTS ENE AWAY
FROM OUR AREA MON/TUE... WITH HEIGHTS CONTINUING TO RISE THROUGH MID-
LATE WEEK AS ATLANTIC RIDGING SLIDES WESTWARD BENEATH THE EXITING
TROUGH AND BUILDS OVER THE MIDATLANTIC AND SOUTHEAST... ENSURING
CONTINUED DEEP LAYER SUBSIDENCE. THICKNESSES START OUT AT THEIR
LOWEST MON MORNING (ABOUT 20 M BELOW NORMAL) THEN RISE INCREMENTALLY
EACH DAY... BACK TOWARD NEAR-NORMAL VALUES BY THU... SO EXPECT HIGHS
IN THE 70S TO NEAR 80 MON/TUE... INCHING UP TO 80-85 RANGE BY THU.
MON AND TUE WILL BE OUR COOLEST MORNINGS WITH LOWS WELL DOWN INTO
THE 50S... WITH SOME UPPER 40S IN OUTLYING AREAS IN THE PIEDMONT.
LOWS WILL RECOVER BACK TO THE MID 50S TO AROUND 60 WED/THU MORNINGS.

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
AS OF 115 PM THURSDAY...

A MOIST AND UNSTABLE AIR MASS ALONG WITH THE APPROACH AND PASSAGE OF
A COUPLE OF SURFACE COLD FRONTS WILL RESULT IN PERIODS OF MVFR/IFR
CEILINGS AND VISIBILITY DUE TO CONVECTION. THE CONVECTIVE THREAT
APPEARS HIGHEST ACROSS CENTRAL NC BETWEEN 19Z-03Z...AND AGAIN FRIDAY
AFTERNOON-EVENING THOUGH MAINLY ALONG AND EAST OF HIGHWAY 1. IN
VICINITY OF THE STORMS...EXPECT WIND GUSTS 25-33KTS AND VISIBILITY
AOB 1SM.

LATER TONIGHT....AFTER 06Z...A LAYER OF LOW CLOUDS WILL DEVELOP
RESULT IN CEILINGS AOB 1000FT. THESE LOW CEILINGS WILL LIKELY
PERSIST WELL INTO FRIDAY MORNING...ESPECIALLY IN VICINITY OF KFAY
AND KRWI.

THE UNSETTLED WEATHER PATTERN WILL PERSIST INTO SATURDAY AS A WELL
DEFINED COLD FRONT APPROACHES FROM THE NW...CROSSING CENTRAL NC
SATURDAY NIGHT. A DRIER MORE STABLE AIR MASS AND ASSOCIATED VFR
CONDITIONS WILL OVERSPREAD CENTRAL NC SUNDAY...LINGERING INTO EARLY
NEXT WEEK.
