AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1051 PM EDT TUE MAY 15 2012
.SYNOPSIS...
A BROAD AND SLOW MOVING UPPER LEVEL TROF WILL CONTINUE TO MOVE EAST
ACROSS THE AREA THROUGH THURSDAY. HIGH PRESSURE WILL THEN BUILD IN
FROM THE NORTH ON FRIDAY AND REMAIN THROUGH EARLY NEXT WEEK.
&&
.NEAR TERM /THROUGH WEDNESDAY/...
AS OF 1045 PM...HAVE OPTED TO KEEP THE FLASH FLOOD WATCH IN PLACE
FOR AT LEAST A COUPLE MORE HOURS AS THE INCOMING 00Z MODELS CONTINUE
TO SHOW UPPER DIVERGENCE INCREASING 03Z TO 06Z WITH SOME RESPONSE
FROM THE NRN UPSTATE THROUGH THE NC PIEDMONT DURING THAT PERIOD.
COVERAGE IS NOT VERY IMPRESSIVE RIGHT NOW...BUT SLOWLY MOVING
THUNDERSTORMS WILL PRODUCE TORRENTIAL RATES IN THE FEW AFFECTED
AREAS...AND CANNOT RULE OUT ISOLD FLASH FLOODING. WILL STEADILY
TAPER POPS THROUGH THE EARLY MORNING HOURS. OTHERWISE...THE FORECAST
IS ON TRACK WITH ONLY MINOR TEMPERATURE ADJUSTMENTS NEEDED.
THE WEAK TROUGH AXIS WILL SLIDE A LITTLE TO THE EAST ON WEDNESDAY
AND THE H5 WINDS WILL BE QUITE LIGHT. OVERALL...THIS SHOULD RESULT
IN MUCH LESS CONVECTIVE COVERAGE OVER THE MTNS. THE UPSTATE AND NE
GA WILL SEE THE BEST COVERAGE. I HAVE 40 POPS IN THIS AREA FOR
NOW...BUT IT WOULDN/T SURPRISE ME TO SEE GREATER COVERAGE THAN THIS
ACROSS THE SE ZONES.
&&
.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
AS OF 215 PM TUESDAY...ON THURSDAY...THE CWA WILL REMAIN IN THE
VICINITY OF THE MID LEVEL TROUGH DURING THE DAYLIGHT HOURS. AT THE
SFC...A NEARLY WEST TO EAST ORIENTED FRONT WILL SLIP SOUTHWARD
ACROSS THE THE SOUTHERN APPALACHIANS DURING THE AFTERNOON. FORECAST
SOUNDINGS INDICATE A WEAK H6 INVERSION...WITH SHALLOW DEEP LAYER
LAPSE RATES. CAPE VALUES MAY REMAIN LIMITED TO LESS THAN 1000 J/KG
DURING THE AFTERNOON. HOWEVER...THE COMBINATION OF THE CYCLONIC FLOW
ALOFT...WEAK INSTABILITY...AND A SFC BOUNDARY SHOULD SUPPORT CHC
POPS ACROSS THE MTNS RIDGES AND SCHC EAST. HIGH TEMPERATURES ARE
EXPECTED TO RANGE FROM THE U70S WITHIN THE MTN VALLEYS TO L80S EAST.
ON FRIDAY...THE H5 TROF AXIS SHOULD TRACK SE AND HEIGHTS SHOULD RISE
ACROSS THE MTNS DURING THE AFTERNOON. AT THE SFC...HIGH PRESSURE
SHOULD SE ACROSS THE WESTERN CAROLINAS AND NE GEORGIA THROUGH THE
DAY...RESULTING IN NE LLVL FLOW. FORECAST SOUNDINGS INDICATE WARM
MID LEVEL TEMPS...KEEPING CAPE VALUES LESS THAN THURSDAY. GIVEN THE
PATTERN...I WILL KEEP POPS LIMITED TO A SCHC ACROSS THE HIGHEST
ELEVATIONS...OTHERWISE...CONDITIONS WILL LIKELY REMAIN DRY.
TEMPERATURES SHOULD RANGE VERY CLOSE TO NORMAL.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AS OF 1230 PM TUESDAY...BASED ON HPC DISCUSSION...I WILL FAVOR THE
0Z ECMWF THROUGH THE EXTENDED PERIOD. BROAD H5 RIDGING IS FORECAST
TO REMAIN ACROSS THE REGION THROUGH THE WEEKEND...THEN A CLOSED LOW
MAY CUT OFF OVER FL ON MON AND LIFT NORTH INTO THE MIDDLE OF NEXT
WEEK. AT THE SFC...WEAK HIGH PRESSURE SHOULD REMAIN RIDGED NE TO SE
ACROSS THE CWA THROUGH MOST OF THE EXTENDED PERIOD. BASED ON THIS
PATTERN...I WILL FAVOR A DRY FORECAST ACROSS THE REGION THIS
WEEKEND. I WILL FORECAST INCREASING SCHC TO CHC POPS MON AND TUES
ACROSS THE CWA. TEMPERATURES SHOULD RANGE WITHIN A FEW DEGREES OF
NORMAL THROUGH THE PERIOD.
&&
.AVIATION /03Z WEDNESDAY THROUGH SUNDAY/...
AT KCLT...SCATTERED SHOWERS AND TSTMS CONTINUE TO DEVELOP OVER THE
NRN UPSTATE...BUT ARE MAKING VERY LITTLE PROGRESS TOWARD KCLT AT
PRESENT. WILL ALLOW THE VCSH MENTION TO END AT 03Z...BUT ADDITIONAL
COVERAGE MAY BE NEEDED INTO THE EARLY MORNING HOURS IF CONVECTION
LIFTS NE AS UPPER DIVERGENCE PASSES. OTHERWISE...MODEL PROFILES SHOW
SOME MVFR CIGS...SO WILL FEATURE A BRIEF WINDOW OF MVFR AROUND
DAYBREAK. FLOW WILL BE VERY LIGHT THROUGH THE PERIOD...MAINLY FROM A
NRLY DIRECTION. HAVE ADDED PROB30 TS FOR WED AFTN IN CONTINUED LOW
LEVEL CONVERGENCE WITH WEAK UPPER SUPPORT.
ELSEWHERE...ISOLD TSTMS ARE MOVING NE AWAY FROM KGSP AND ARE NOT
THREATENING ANY TAF SITES AT PRESENT. ISOLD TO SCT COVERAGE MAY
CONTINUE FOR A FEW MORE HOURS AS UPPER DIVERGENCE PASSES. ANY
AIRFIELDS RECEIVING APPRECIABLE RAINFALL LATE THIS EVENING MAY
EXPERIENCE IFR CONDITIONS OVERNIGHT...BUT ONLY KAVL HAD MUCH EARLIER
TODAY. BRIEF MVFR IS GENERALLY EXPECTED EVERYWHERE BUT KAVL...WHERE
SOME IFR IS LIKELY. WINDS WILL REMAIN LIGHT THROUGH THE
PERIOD...WITH A NRLY FLOW DEVELOPING. A FEW THUNDERSTORMS WILL BE
POSSIBLE TOMORROW AFTERNOON IN CONTINUED INSTABILITY...HIGH BOUNDARY
LAYER MOISTURE...WEAK SFC CONVERGENCE...AND WEAK UPPER TRIGGERING.
OUTLOOK...EXPECT ISOLD LATE DAY SHOWERS AND TSTMS THROUGH
FRIDAY...ESPECIALLY IN THE MOUNTAINS...WITH MORE DRYING OVER THE
WEEKEND. MORNING FOG WILL BE POSSIBLE...ESPECIALLY IN THE MTN
VALLEYS AND NEAR LAKES/RIVERS.
