Flash Flood in Virginia, June 29, 2014

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
336 PM EDT SUN JUN 29 2014

.SYNOPSIS...
WEAK HIGH PRESSURE CENTERED EAST OF THE NEW JERSEY COAST WILL
BEGIN TO DRIFT FURTHER OUT INTO THE NORTH ATLANTIC OVER THE NEXT
DAY OR SO AS A POTENTIAL TROPICAL SYSTEM DEVELOPS OFF THE
FLORIDA COAST. SCATTERED SHOWERS AND A FEW THUNDERSTORMS ARE
POSSIBLE THIS EVENING AND AGAIN ON MONDAY.

&&

.NEAR TERM /THROUGH MONDAY/...
AS OF 320 PM EDT SUNDAY...

FORECAST AREA REMAINS UNDER AN UPPER LEVEL RIDGE WITH WEAK HIGH
PRESSURE STILL OFF THE MID-ATLANTIC COAST AND A POTENTIAL TROPICAL
SYSTEM LOCATED EAST OF THE FLORIDA COAST. THIS PATTERN HAS
MAINTAINED AN EASTERLY FLOW FOR SEVERAL DAYS ACROSS THE AREA WITH
DRIER AIR...DEWPOINTS STILL IN THE MID-50S OVER EASTERN VA BACK
INTO THE PIEDMONT THAN OVER THE MOUNTAINS AND WESTWARD WHERE
MID-60S TO LOW 70S DEWPOINTS ARE FOUND.

NUMEROUS SHOWERS AND THUNDERSTORMS CONTINUE TO DEVELOP WEST OF
THE CWA THIS AFTERNOON IN THE MUCH MORE UNSTABLE AIR ACROSS
EASTERN KY AND SOUTHERN WV WHERE CAPES RANGE FROM 1500 TO 2500
J/KG. THESE STORMS HAVE PUSHED INTO OUR THE WESTERN COUNTIES OF
THE CWA EARLY THIS AFTERNOON AND COULD BRING POCKETS OF MODERATE
TO HEAVY RAINFALL...MEAN CELL MOVEMENT HAS BEEN GENERALLY 10 TO
15 MPH LIMITING RESIDENCE TIME OVER SMALL STREAM BASINS WHILE RATES
REMAIN MODEST EXCEPT IN A FEW ISOLATED CELLS...GENERALLY IN THE
1-2 INCH PER HOUR RANGE LIMITING THE FLOOD THREAT. SPC MESO-
ANALYSIS CONTINUES TO SHOW MUCH LESS INSTABILITY ACROSS MOST OF
THE CWA AND STILL PLENTY OF CLOUDS SO THE EXPECTATION IS THAT THE
INTENSITY OF STORMS WILL DIMINISH AS THEY PUSH EAST WHICH HAS BEEN
THE CASE SO FAR THIS AFTERNOON. COVERAGE AND INTENSITY OF
RAINFALL WILL DIMINISH LATE THIS EVENING AS DAYTIME ENDS. WIDELY
SCATTERED SHOWERS REMAIN POSSIBLE DUE TO OUTFLOW BOUNDARIES WELL
INTO THIS EVENING MAINLY ACROSS THE MOUNTAINS...HAVE KEPT A SLIGHT
CHANCE OF RAIN IN THE FORECAST FOR THE NIGHT. OVERNIGHT LOWS WILL
GENERALLY BE IN THE MID/UPPER 60S MOST LOCATIONS.

PATTERN FOR MONDAY SHOWS ONLY SLIGHT CHANGES AS THE UPPER LEVEL RIDGE
AXIS SHIFTS SLIGHTLY FURTHER EAST AND A SOMEWHAT MORE ZONAL FLOW
DEVELOPS ALOFT. THE ATLANTIC SURFACE HIGH WILL BE RELAXING ITS
INFLUENCE WITH A MORE TYPICAL WEST TO SOUTHWEST FLOW SLOWLY DEVELOPING.
STILL A CHANCE FOR SHOWERS AND A FEW THUNDERSTORMS WITH HIGHEST
POPS/QPF OVER THE NC MOUNTAINS AND TEMPS NOT MUCH DIFFERENT THAN
TODAY ALTHOUGH PERHAPS MORE SUN COULD GIVE A SLIGHT BUMP.

&&

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
AS OF 300 PM EDT SUNDAY...

THE NATIONAL HURRICANE CENTER (NHC) GIVES THE SURFACE LOW OFFSHORE
FLORIDA A 60 PERCENT CHANCE TO DEVELOP INTO A TROPICAL CYCLONE OVER
THE NEXT COUPLE DAYS. THIS SYSTEM WILL FIRST DRIFTS SOUTHWARD THEN
LIFTS NORTHEAST DURING THE PERIOD. THE LATEST NHC FCST IS CLOSE TO
THE ECMWF...WITH A LIKELY TROPICAL STORM LIFTING NORTHEAST JUST
OFFSHORE...AHEAD OF A COLD FRONT THAT IS EXPECTED TO CROSS OUR AREA
FROM THE WEST ABOUT THURSDAY. SO AT THIS TIME...STILL NOT EXPECTING
ANY DIRECT IMPACT FROM THAT SYSTEM. SEE NHC FOR THE LATEST
INFORMATION CONCERNING FURTHER DEVELOPMENT OF THIS SYSTEM INTO A
TROPICAL CYCLONE.

CLOSER TO HOME...HIGH PRESSURE WEAKENS MONDAY EVENING INTO MONDAY
NIGHT AS 5H HEIGHTS FLATTEN AND LOWER WITH TROUGH HEADING INTO THE
UPPER MS VALLEY. THE SFC FLOW BECOMES MORE SOUTH TO SOUTHWEST. WITH
FLOW ALOFT BECOMING WEST THE POTENTIAL FOR UPSTREAM CONVECTION
MOVING IN IS HIGHER...ESPECIALLY MONDAY NIGHT TOWARD TUESDAY.
INCREASED POPS MONDAY EVENING THEN DECREASED POPS INTO TUESDAY
MORNING. PLAYED LOW TEMPERATURES CLOSE TO ADJMAVBC WITH READINGS
FROM THE LOWER 60S IN THE MOUNTAINS TO AROUND 70 DEGREES IN THE
PIEDMONT.

ON TUESDAY...THE MAIN SFC FRONT REMAINS WEST AND NORTHWEST OF US
ACROSS THE OHIO VALLEY AND MIDWEST. THE RIDGE ALOFT LIFTS BACK A BIT
IN RESPONSE TO THE UPPER TROUGH OVER THE UPPER MIDWEST. INCREASED
POPS AND KEPT BEST CHANCES ACROSS THE NORTH WITH THE BETTER LIFT.
LEANED HIGH TEMPERATURES TUESDAY TOWARDS THE ADJMETBC WITH VALUES
FROM THE LOWER TO MID 80S IN THE WEST TO THE LOWER 90S ACROSS THE
PIEDMONT.

GFS...NAM AND ECMWF KEEP MOST OF TUESDAY NIGHT DRY. GFS AND ECMWF
BRING A FEW SHOWERS AND THUNDERSTORMS TO THE NORTHWEST BY WEDNESDAY
MORNINGS ESPECIALLY OVER SOUTHEAST WEST VIRGINIA. THE NAM DEPICTS A
SLIGHTLY FASTER SOLUTION. HELD ON TO LIGHT POPS FOR LATE TUESDAY
NIGHT INTO WEDNESDAY IN THE NORTHWEST.  TUESDAY NIGHT WILL BE MUGGY
WITH LOWS GENERALLY FROM THE MID 60S IN THE WEST TO THE LOWER 70S IN
THE EAST.

WEDNESDAY WILL BE A BETTER CHANCE OF SHOWERS AND THUNDERSTORMS AS
LOW LVL CONVERGENCE AHEAD OF THE FRONT PLUS LEE SIDE TROUGH
CONVERGENCE WILL BE ENOUGH TO OVERCOME THE CAP ALOFT. SPC DAY 4
SEVERE WEATHER OUTLOOK INDICATED POTENTIAL TOO LOW TO MENTION AT
THIS TIME. HIGH TEMPERATURES WEDNESDAY AFTERNOON WILL WARM TO HIGHS
FROM THE LOWER 80S IN THE MOUNTAINS TO THE LOWER 90S IN THE
SOUTHEAST.

FRIST FRONTAL BOUNDARY IS ACROSS OUR REGION WEDNESDAY NIGHT AS COLD
FRONT REACHES THE OHIO VALLEY. MEANWHILE...LOW PRESSURE REMAINS OFF
THE SOUTH CAROLINA COAST.  ALLOWED FOR SOME LIGHT POPS WEDNESDAY
NIGHT WITH SOME THINNING IN THE MIDDLE. LOWS WEDNESDAY WILL BE
MAINLY FROM LOWER 60S IN THE WEST TO LOWER 70S IN THE EAST.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
AS OF 300 PM EDT SUNDAY...

ON THURSDAY...THE COLD FRONT CONTINUES TO TRAVEL SOUTHEAST AND
SHOULD PUSH TOWARDS THE ATLANTIC IN THE WAKE OF THE FRONTAL
PASSAGE...HIGH PRESSURE WILL BUILD SOUTH FROM THE OHIO VALLEY.
MEANWHILE...LOW PRESSURE WILL LIFT NORTHEAST UP THE MID ATLANTIC
COAST.

SFC HIGH PRESSURE WILL BUILD SOUTH INTO OUR REGION ON FRIDAY...WITH
DRIER AND MORE STABLE AIR MASS. THERE ARE SOME CONCERNS THAT
SUBTROPICAL RIDGE AND PLACEMENT OF THE FRONT TO OUR SOUTH AND ITS
ASSOCIATED DEEPER MOISTURE...COULD TRIGGERS A FEW SHOWERS AND
THUNDERSTORMS ACROSS SOUTHERNEASTERN PORTIONS OF FORECAST AREA
FRIDAY AFTERNOON INTO FRIDAY EVENING.

LOW WILL SLOWLY LIFT NORTHEAST OFF THE COAST SATURDAY INTO SATURDAY
NIGHT. ITS IMPACTS TO THE MID-ATLANTIC COAST APPEAR MINIMAL AS
MODELS PUSH IT OUT TO SEA. WITH SOME LOW LEVEL MOISTURE STILL IN OUR
REGION...DECIDED TO USED HPCGUIDE LIGHT POPS FOR THE HOLIDAY WEEKEND.

TEMPERATURES EXPECTED TO BE SLIGHT ABOVE NORMAL THURSDAY AND
THEN NEAR NORMAL FOR THE HOLIDAY WEEKEND.

&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
AS OF 140 PM EDT SUNDAY...

WESTERN TAF SITES..ESP LWB/BLF COULD SEE SHOWER OR THUNDERSTORM
THIS AFTERNOON OR EARLY EVENING WITH BRIEF REDUCTIONS IN
CIGS/VSBYS BUT EXPECT EASTERN TAF SITES TO REMAIN DRY WITH SCT TO
BKN CLOUDS BUT MAINLY VFR CONDITIONS.

THIS EVENING...SHOWERS/TSRA END AND CIGS DROP BACK TO MVFR AT
LEAST IN THE MTNS WHILE THE ROA/LYH/DAN GROUPS STAY VFR.
FOG COULD BE AN ISSUE AT BLF/BCB/LWB WITH RAIN TODAY...AND SOME
CLEARING OF THE LOWER CLOUDS OVERNIGHT. ATTM...MAINLY STICKING
WITH IFR VSBYS AT LWB/BCB AND MVFR AT BLF. POTENTIAL IS THERE FOR
EVEN LOWER WITH STRATUS DECK UNDER 1KFT AT BLF.

EXTENDED AVIATION...

MONDAY WILL BE ALMOST A REPEAT OF TODAY...THOUGH BETTER CHANCE OF
STORMS TO THE EAST. OUTSIDE OF STORMS...EXPECT VFR CONDITIONS. A
BREAK IN THE WEATHER OCCURS TUESDAY...THOUGH CANNOT FULLY RULE OUT
ISOLATED SHRA/TSRA IN THE MTNS. ISSUES OF FOG AND STRATUS LINGER
MON NIGHT BUT AS FLOW BECOMES MORE SW THE EASTERN TAF SITES WILL
NOT BE DEALING WITH AS MUCH LOW DECK IN THE MORNING.

FRONTAL BOUNDARY AND UPPER TROUGH HEAD EAST INTO THE AREA BY
MIDWEEK...WITH GOOD CHANCE OF SHOWERS AND STORMS. FRONTAL SYSTEM
MAY LINGER INTO THURSDAY OVER THE MTNS...KEEPING THE CHANCE OF
SHOWERS AND STORMS AROUND. ALSO EXPECT SAME ISSUES AT NIGHT WITH
ANY FOG IN THE MTNS AND WHERE IT RAINS.
