Area forecast discussion, Apr 16, 11:18 AM EDT, 1 hour 12 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1118 AM EDT SAT APR 16 2011

.SYNOPSIS...
A COLD FRONT WILL TRACK MOVE OFF THE COAST THIS EVENING. A SURFACE
RIDGE WILL BUILD OVER THE REGION SUNDAY AND REMAIN INTO MID WEEK.
ANOTHER COLD FRONT IS EXPECTED TO AFFECT THE AREA FOR THE LAST PART
OF THE WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AT 1115 AM...UPDATED TO ADD THE NW PIEDMONT TO TORNADO WATCH 149.
THINKING FROM THE 1045 UPDATE REMAINS THE SAME.

THE LINE OF STORMS ASSOCIATED WITH THE COLD FRONT WILL CONTINUE TO
MOVE EAST. BEHIND THE LINE EXPECT CLEARING SKIES...INCREASING
GRADIENT WINDS AND AN END TO THE PRECIP. HAVE LOWERED FCST HIGHS
BASED ON CURRENT OBS AND LATEST FCST DATA. STILL EXPECT CLOUDS AND
SCT SHOWERS TO COME BACK INTO THE MTNS IN WRAP AROUND MOISTURE AND
NW FLOW.

LATEST WV IMAGES INDICATED A MID LEVEL LOW OVER THE CENTRAL CONUS
WITH A PLUME OF MOISTURE FROM THE FL PANHANDLE NORTH ACROSS THE
APPALACHIANS. DRY AIR WRAPPING ON THE SOUTHERN SIDE OF THE LOW
SHOULD BEGIN TO MOVE EAST ACROSS THE SOUTHERN APPALACHIANS DURING
THE PRE DAWN HOURS...PUSHING ACROSS THE REMAINDER OF THE CWA THROUGH
THE AFTERNOON. RECENT RADAR IMAGES SHOW A SHARP LINE OF WEAK
REFLECTIVITY ASSOCIATED WITH THE SFC COLD FRONT/DRY AIR NEAR THE
AL/GA/TN LINE. AREAS OF MODERATE SHRA AND ISO EMBEDDED TSRA EXTENDED
FROM THE VICINITY OF THE COLD FRONT EAST ACROSS THE PIEDMONT OF THE
CAROLINAS. CAPE ACROSS THE REGION REMAINS VERY LIMITED TO NEAR ZERO.
HOWEVER...0 TO 1 KM HELICITY VALUES RANGE FROM 300 TO 400 M2/S2
AHEAD OF THE FRONT. IN ADDITION...QG FORCING ASSOCIATED WITH THE
CENTRAL CONUS LOW WILL PEAK ACROSS THE CWA BETWEEN 12 TO 18Z. IT
APPEARS THAT THE SHRA CLUSTERS WILL CONTINUE ACROSS THE CWA AHEAD OF
THE COLD FRONT. THE COLD FRONT IS FORECAST TO MOVE ACROSS THE UPPER
SAVANNAH RIVER VALLEY AROUND 15Z...AND REACHING THE CLT METRO AREA
AROUND 21Z. POPS WILL REMAIN NEAR 100 PERCENT AHEAD OF THE
FRONT...BUT WILL FALL SHARPLY AS THE BOUNDARY BEGINS TO MOVE WEST TO
EAST ACROSS THE FORECAST AREA. SVR TSRA POTENTIAL APPEARS VERY
LIMITED THIS MORNING. INSTABILITY IS EXPECTED TO INCREASE RAPIDLY
AFTER SUNRISE...ESPECIALLY ALONG AND EAST OF THE I-77 CORRIDOR. 4KM
WRF INDICATES THAT A LINE OF ORGANIZED TSRA WILL DEVELOP ALONG THE
FRONT OVER THE NC PIEDMONT THIS AFTERNOON. BASED ON THE TIMING OF
THE FRONT I WOULD ANTICIPATE THAT THE LINE WILL INITIATE EAST OF
I-77 DURING THE MID TO LATE AFTERNOON. THE STORMS THAT DEVELOP
WITHIN THE CWA WILL HAVE THE POTENTIAL FOR DAMAGING WINDS/HAIL AND
BRIEF TORNADOES...WILL HIGHLIGHT IN THE HWO.

OBSERVED RAINFALL ACROSS THE EAST FACING SLOPES OF THE WESTERN NC
MTNS RANGED FROM NEAR 3 INCHES TO 1 INCH. AREA RIVERS AND STREAMS
HAVE STARTED TO RISE...POSSIBLE YIELDING NEAR BANKFULL LEVELS WITHIN
THE HEADWATERS LATER TODAY. AN ADDITIONAL 1 TO 1.5 INCHES MAY FALL
OVER THE REGION BEFORE RAINFALL ENDS.

FORECAST SOUNDINGS INDICATE THAT POST FRONTAL MIXING HEIGHTS WILL
INCREASE TO 6 TO 8 KFT THIS AFTERNOON. WINDS WITHIN THE MIXED LAYER
WILL GENERALLY RANGE FROM 30 TO 40 KTS...WITH SFC GUSTS REACHING
NEAR 30 KTS. BASED ON THE CURRENT WIND OBS AND EXPECTED MIXING WINDS
TODAY...I WILL ISSUE A LAKE WIND ADVISORY FOR THE ENTIRE
CWA...KEEPING THE MORNING WIND ADVISORY FOR THE TN BORDER COUNTIES.

TEMPERATURES WILL PEAK NEAR NORMAL THIS AFTERNOON.
TONIGHT...CLEARING CONDITIONS WILL CAA SHOULD RESULT IN MIN TEMPS 3
TO 5 DEGREES BELOW NORMAL. TEMPERATURES ACROSS THE MTNS WILL RANGE
IN THE MID TO UPPER 30S...WITH BREEZY NORTHWEST WINDS.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
AS OF 330 AM SATURDAY...FRONT MOVES WELL E OF CWA SAT NIGHT WITH NW
FLOW SHWRS LINGERING OVER TN BORDER MTNS AND A PERIOD OF LGT SNOW
MIXING IN WITH RAIN AT THE HIGHER ELEVATIONS BEFORE PRECIP ENDS
AROUND DAYBREAK. LOWS WILL BE WITHIN A DEG OR TWO OF AVG SAT
NIGHT...THEN A DEG OR TWO ABOVE AVG SUN AS A RIDGE BUILDS INTO THE
AREA UNDER MSUNNY SKIES. RIDGE AXIS MOVES OFFSHORE MON WITH S FLOW
DEVELOPING ACROSS THE REGION. TEMPS SHOULD BE A COUPLE CATEGORIES
ABOVE AVG.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
AS OF 330 AM SATURDAY...A WEAK UPPER RIDGE BUILDS OVER THE AREA MON
NIGHT INTO TUE WITH A SFC HIGH OFF THE SE COAST RIDGING UP INTO THE
AREA. EXPECT PCLOUDY SKIES WITH ABOVE AVG TEMPS FOR THE FIRST PART
OF THE WEEK. A SERIES OF WEAK UPPER WAVES MOVE ACROSS THE REGION
WED-THU WITH A COLD FRONT EXPECTED TO APPROACH THE CWA FROM THE NW
WED NIGHT-THU. THIS WILL BRING A CHC OF SHWRS AND TSTMS TO THE
AREA...ESP TO THE MTNS. THE ECMWF PUSHES THE FRONT THRU THE CWA THU
AND WASHES IT OUT TO THE S WHILE THE GFS STALLS THE FRONT ALONG THE
S CWA AND MAINTAINS HIGHER CHC POPS THRU FRI. USED A BLEND FOR
SLIGHT CHC TO CHC POPS...ESP OVER THE MTNS...WED AFTN-FRI. TEMPS ARE
EXPECTED TO REMAIN ABOVE AVG.

&&

.AVIATION /15Z SATURDAY THROUGH WEDNESDAY/...
AT KCLT...GUSTY SOUTHEAST WINDS WILL CONTINUE ACROSS THE TERMINAL
THROUGH THE PRE DAWN HOURS...THEN VEERING SOUTH AN HOUR OR TWO AFTER
SUNRISE. SHRA WILL BRING TEMPO REDUCTIONS TO VIS THIS MORNING AND
AFTERNOON. MOS AND FORECAST SOUNDINGS INDICATE THAT CEILINGS WILL
REMAIN OR LOWER TO IFR THIS MORNING...WITH A GRADUAL IMPROVEMENT TO MVFR
BY MID DAY. WINDS WILL CONTINUE TO VEER THROUGH THE DAYLIGHT
HOURS...ESPECIALLY AS A COLD FRONT CROSSES THE TERMINAL DURING THE
MID AFTERNOON. CB SHOULD HOLD OFF UNTIL MID MORNING AND REMAIN UNTIL
