AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
727 PM EDT SUN JUN 25 2006

.AVIATION...

CHALLENGING AVIATION FORECAST THE NEXT 24 HOURS. LATE SUNDAY
AFTERNOON...A OUTFLOW BOUNDARY PROGRESSED WEST ACROSS THE REGION
AN INTERSECTED ONE PROGRESSING TOWARDS THE EAST. THE INTERSECTION
OF THESE TWO BOUNDARIES COINCIDED CLOSE TO A STALLED FRONTAL
BOUNDARY NEAR A KHSP-KBCB-KGEV LINE. A CONTINUOUS LINE OF SHOWERS
AND STORMS EXTEND NORTHEAST TO SOUTHWEST ALONG THIS FEATURE. EAST
OF THIS LINE OF STORMS...THE AIR HAS STABLIZED FOR THE TIME WITH
PROGRESSIVELY LOWERING STATO-CUMULUS AND STATO-FRACTUS CEILINGS
INTO THE IFR AND LIFR RANGE. ANTICIPATE THIS LEVEL OF CEILING TO
CONTINUE THROUGHOUT THE NIGHT WITH VISIBILITIES FALLING INTO THE
IFR RANGE. ADDITIONAL SHOWERS MAY IMPACT THIS REGION LATER THIS
EVENING AND TOWARDS MIDNIGHT. WEST OF THE CONVECTIVE LINE...EXPECT
SHOWERS AND STORMS TO INCREASE IN COVERAGE AS THE CONVECTIVE LINE
SLOWLY LIFTS NORTH. THUNDERSTORMS IN THE KLWB AND KBLF AREAS WILL
BE VERY COMMON THROUGH AT LEAST MIDNIGHT WITH CEILINGS AND
VISIBILITIES ANYWHERE BETWEEN LIFR AND VFR.

EXPECT MUCH OF THE PRECIPITATION TO HAVE ENDED ACROSS THE ENTIRE
REGION BY THE PRE-DAWN HOURS WITH IFR OR LOWER CEILINGS/VIS IN
MOST PLACES. RECOVERY TO VFR CONDITIONS SHOULD BE GRADUAL AFTER
SUNRISE...WITH CONVECTION FIRING AGAIN BY THE EARLY AFTERNOON.

.PREV DISCUSSION...
 (ISSUED 314 PM EDT SUN JUN 25 2006)

SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...

MAIN CONCERN IS OBVIOUSLY CONTINUED HEAVY RAIN POTENTIAL THRU LATE
TUESDAY. LATE MORNING ANALYSIS REVEALED STATIONARY FRONTAL BOUNDARY
LAYING THRU CENTRAL WEST VIRGINIA...WITH PLENTY OF JUICE SOUTH OF
THE FRONT AS EVIDENCED BY DEW POINTS IN THE UPPER 60S TO MIDDLE 70S
AND MORNING SOUNDING PWATS OF 1.7+ INCHES. TO THE WEST...INITIAL
SHORTWAVE HUNG ACRS SOUTHERN IN/IL WITH MUCH STRONGER IMPULSE DIVING
SOUTH INTO NRN IA. THIS IN ASSOCIATION WITH ONSHORE PUSH OF COPIOUS
TROPICAL MOISTURE FROM WEAK SYSTEM OFF THE EAST COAST OF
FLORIDA...HAS HELPED SUFFICIENTY BACK THE FLOW TO SHOVE THE H85
FRONT JUST ENOUGH WEST TO FOCUS THE HEAVY RAIN THIS MORNING OVR THE
FAR WESTERN CWA INTO WEST VIRGINIA. IN ADDITION...WEAK SUBSIDENCE ON
NRN FRINGE OF APPROACHING SYSTEM FROM THE SOUTHEAST HAS ALLOWED FOR
CLEARING SKIES AND GOOD DESTABILIZATION TO TAKE PLACE. AS
SUCH...EXPECT COVERAGE OF SHRA/TSRA WILL AGAIN INCREASE QUICKLY THIS
AFTN AND EVENING AND WILL RUN WITH CATEGORICAL POPS THRU EARLY
MONDAY AS SLUG OF TROPICAL MOISTURE PUSHES INTO THE REGION. COULD
CATCH A BREAK FOR A TIME TOMORROW AFTN AS MID LEVEL DRY AIR WRAPPING
INTO TROPICAL SYSTEM GETS DRAWN UP OVR THE AREA...ALTHOUGH STILL
ANTICIPATE SOME PRECIP AROUND.

BETTER CHANCES LOOK TO RETURN LATE MONDAY INTO EARLY TUESDAY AS
REMNANTS OF SYSTEM HEAD NORTH INTO THE REGION AND FRONTAL BOUNDARY
REMAINS SUFFICIENTLY CLOSE TO FOCUS HEAVIER PRECIP. ALSO SOME
POTENTIAL FOR UPSLOPE ENHANCEMENT COME MONDAY NIGHT AS WEAK SFC LOW
APPROACHES AND HELPS BACK THE LOW LEVEL FLOW EVEN MORE
EASTERLY...ALTHOUGH EXACT TRACK OF THIS SYSTEM STILL REMAINS A BIT
UNCERTAIN. THAT SAID...AND GIVEN MANY AREAS ALREADY PRIMED BY HEAVY
RAIN OVER THE PAST FEW DAYS...WILL EXTEND THE FLASH FLOOD WATCH
UNTIL 23Z ON TUESDAY AND ALSO EXPAND IT TO COVER THE ENTIRE CWA.

TEMPS THRU THE PERIOD NOT LIKELY TO SHOW ANY BIG DIURNAL RANGES AS
AIRMASS REMAINS TROPICAL IN NATURE AND CLOUDS LIKELY HANG TOUGH. HAVE
GENERALLY GONE A FEW DEGREES ABOVE GUIDANCE FOR OVERNIGHT LOWS AND
STAYED CLOSE ON HIGHS...ALTHOUGH AS ALWAYS ANY QUICK BREAKS OF SUN
CAN RESULT IN SLIGHTLY WARMER TEMPS.

LONG TERM /WEDNESDAY THROUGH SUNDAY/...

PATTERN LOOKS TO TAKE A SMALL BREAK ON WEDNESDAY AS WESTERN ATLANTIC
RIDGE SHIFTS ENOUGH TO ALLOW THE SFC BOUNDARY TO SLIP EAST INTO THE
PIEDMONT BEFORE HANGING UP THRU THE END OF THE PERIOD AS FLOW ALOFT
TURNS PARALLEL TO BOUNDARY. COVERAGE OF SHOWERS/STORMS DOES NOT
APPEAR AS WIDESPREAD AS WHAT IS ONGOING...HOWEVER STILL ENOUGH TO
JUSTIFY CHANCE POPS AS UPR TROUGH TO THE WEST SLOWLY INCHES EAST. IN
EFFECT...AREA WILL REMAIN PINNED IN BETWEEN APPROACHING UPR TROUGH
FROM THE WEST AND STUBBORN ATLANTIC RIDGE WITH TEMPS REBOUNDING
CLOSER TO NORMAL UNDER WEST/SOUTHWEST FLOW ALOFT. PERHAPS SOME
COOLER TEMPS AND DRIER WEATHER BY THE UPCOMING WEEKEND WITH GOOD
AGREEMENT AMONG ENSEMBLES/GFS/ECMWF/CANADIAN THAT UPR TROUGH WILL
BE NEARLY OVERHEAD OR JUST EAST OF THE AREA.

AVIATION...

VFR/MVFR CONDITIONS WITH WIDESPREAD IFR/LIFR CONDITIONS IN
CONVECTION AND FOG. A FRONTAL BOUNDARY WILL REMAIN STALLED ACROSS
THE MOUNTAINS DURING THE PERIOD. VERY MOIST AND UNSTABLE AIRMASS
WILL RESULT IN NUMEROUS SHOWERS AND THUNDERSTORMS. SOME OF THE
STORMS WILL CONTAIN HEAVY RAINS. MOUNTAINS OBSCURATIONS ARE POSSIBLE
DURING THE PERIOD.
