AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE COLUMBIA SC
106 PM EDT TUE JUN 25 2013

.SYNOPSIS...
A DEEPENING UPPER LEVEL TROUGH OVER THE EASTERN US...ALONG WITH
ABUNDANT ATMOSPHERIC MOISTURE...WILL PROVIDE ABOVE NORMAL CHANCES
OF MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS THROUGH
THE FORECAST PERIOD.

&&

.NEAR TERM /THROUGH TONIGHT/...
THIS AFTERNOON...HIGH PRESSURE WILL REMAIN OFFSHORE WITH A MOIST
SOUTHERLY FLOW PERSISTING ACROSS THE REGION. CHANCES OF SHOWERS
AND THUNDERSTORMS WILL CONTINUE TO INCREASE THROUGH THE AFTERNOON
HOURS. SEVERE THUNDERSTORM THREAT REMAINS LOW. WITH PWAT VALUES
OF 1.9 INCHES OR GREATER THE POTENTIAL FOR HEAVY RAIN WILL BE THE
BIGGEST ISSUE. WITH FLOW ALOFT ALSO REMAINING WEAK THE HEAVY
RAINFALL COULD COMBINE WITH SOME SLOW MOVING CELLS TO CREATE HYDRO
RELATED ISSUES...ESPECIALLY IN LOW LYING AREAS AND AREAS WHICH
HAVE RECEIVED LARGE AMOUNTS OF RAINFALL IN THE PAST COUPLE OF
DAYS. TEMPERATURES WILL BE AROUND 90...WITH SHOWERS AND THUNDERSTORMS
CREATING A WIDE VARIANCE IN TEMPERATURES THROUGH THE AFTERNOON.

TONIGHT...CONVECTION WILL DIMINISH WITH SUNSET AND LOSS OF
HEATING...WITH FOG POTENTIAL LATE TONIGHT ONCE AGAIN BEING A
CONCERN. WINDS ALOFT WILL BE A BIT STRONGER OVERNIGHT RESULTING IN
A POTENTIAL FOR FOG AND STRATUS. HAVE CONTINUED WITH MENTION OF
PATCHY FOG IN THE FORECAST. OVERNIGHT LOWS WILL AGAIN BE IN THE
LOWER 70S.

&&

.SHORT TERM /WEDNESDAY THROUGH FRIDAY NIGHT/...
UPPER HIGH WILL BUILD OVER THE SW US...WHILE UPPER ENERGY SHIFTS
EAST AND CUTS OFF OVER THE E GREAT LAKES...RESULTING IN A
DEEPENING UPPER TROUGH OVER THE SE CONUS. WEAK SURFACE RIDGE AXIS
WILL REMAIN GENERALLY JUST TO OUR SOUTH INTO WED...THEN SHIFT TO
THE S AND E WED NT/THU AHEAD OF AN UPPER DISTURBANCE AND SURFACE
TROUGH THAT WILL MOVE THROUGH LATE THU/THU NT. HIGH LEVELS OF
ATMOSPHERIC MOISTURE ARE EXPECTED TO CONTINUE THROUGH THURSDAY.
GENERALLY DIURNAL HIGH CHANCE TO LOW LIKELY POPS WED/THU...WITH
INDICATIONS OF SOME DRIER AIR ENTERING THE WESTERN CAROLINAS AND
OUR NORTHERN FA BEHIND THE TROUGH FRIDAY. SO...TRENDED POPS DOWN
FRIDAY...ESP NORTH FA.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
GFS/ECMWF INDICATE UPPER ENERGY ROUNDING THE BASE OF THE UPPER
TROUGH AND MOVING THROUGH OUR REGION SAT/SUN. CONTINUED VERY HIGH
PW VALUES. BY MON INTO MID WEEK...ADDITIONAL UPPER ENERGY WILL
DIVE DOWN THE BACK SIDE OF THE NEARLY STATIONARY UPPER LOW OVER
THE LAKES...AND DEEPEN THE UPPER TROUGH TO OUR WEST OVER THE MISS
VLLY...AS STRONG UPPER RIDGE CONTINUES OVER THE W CONUS. THERE
APPEARS TO BE THE POSSIBILITY THAT A PROLONGED PERIOD OF A DEEP S
TO SW FLOW AND A VERY MOIST ATMOSPHERE COULD SET UP OVER OUR
REGION...PROVIDING ABOVE NORMAL POPS/RAINFALL...AND POSSIBLE
FLOODING. A BLEND OF MOS AND HPC GUIDANCE GENERALLY PROVIDING HIGH
CHANCE TO LIKELY POPS...WHICH LOOKS GOOD.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
MIX OF CONDITIONS ARE EXPECTED TO OCCUR THROUGH THE PERIOD.
CONDITIONS THROUGH THE DAY WILL BE DEPENDENT UPON WHETHER SHOWERS OR
STORMS CAN IMPACT A TAF SITE.  OUTSIDE OF THE PRECIP...EXPECT VFR
CONDITIONS WITH SCATTERED TO BROKEN CLOUDS BETWEEN 3.5KFT AND 5KFT.
IF A SITE IS IMPACTED BY RAINFALL...BRIEF PERIODS OF MVFR
VISIBILITIES AND CEILINGS ARE EXPECTED TO OCCUR.  CONFIDENCE RIGHT
NOW IN REGARDS TO SHOWERS IMPACTING A TAF SITE ARE ABOUT 50
PERCENT...WHICH MATCHES THE SCATTERED NATURE OF THE CONVECTION
THROUGH THE AFTERNOON.  WILL PROBABLY GO WITH VCSH/VCTS SINCE
SHOWERS WILL BE AROUND AND NEAR AIRPORTS...THEN AMEND AS STORMS MOVE
INTO TAF LOCATION.  WINDS THROUGH THE PERIOD WILL GENERALLY BE
SOUTHERLY AT 7 KNOTS OR LESS. MAY SEE A RETURN OF MVFR/IFR FOG OR
STRATUS AGAIN WEDNESDAY MORNING.  THE REST OF WEDNESDAY SHOULD BE
SIMILAR TO WHAT WE HAVE SEEN THE PAST FEW DAYS...SKIES BREAKING OUT
AROUND 14Z...THEN VFR THROUGH 18Z WITH ISOLATED SHOWERS STARTING
AROUND 16Z.

EXTENDED AVIATION OUTLOOK...CIG/VSBY RESTRICTIONS POSSIBLE EACH
DAY IN MAINLY AFTERNOON/EVENING THUNDERSTORMS...AS WELL AS LATE
NIGHT/EARLY MORNING FOG/STRATUS.
