AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
216 PM EDT THU SEP 4 2014

.SYNOPSIS...
A DIFFUSE FRONTAL BOUNDARY NEAR THE NORTH CAROLINA/VIRGINIA LINE
WILL DISSIPATE THROUGH FRIDAY...BUT ABUNDANT MOISTURE...HEAT...AND
INSTABILITY WILL REMAIN SUPPORTING SCATTERED SHOWERS AND THUNDERSTORMS.
A NEW FRONTAL SYSTEM WILL MOVE INTO THE REGION FROM THE NORTHWEST
SATURDAY ACCOMPANIED BY WIDESPREAD THUNDERSTORMS. THIS FRONT WILL
STALL SOUTH OF THE REGION INTO EARLY NEXT WEEK...WITH CHANCES FOR
SHOWERS AND THUNDERSTORMS LINGERING...ALTHOUGH COOLER...MORE
SEASONAL TEMPERATURES ARE EXPECTED BEHIND THE FRONT EARLY NEXT
WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 210 PM EDT THURSDAY...

SLOW MOVING SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ALONG
MOUNTAIN RIDGES THIS AFTERNOON. THERE ARE ALSO SCATTERED SHOWERS
AND THUNDERSTORMS MOVING ACROSS NORTHERN NORTH CAROLINA INTO
SOUTHERN VIRGINIA. ALL THESE STORMS ARE VERY EFFICIENT RAIN
PRODUCERS WITH UP TO AN INCH PER HOUR IN STRONGER STORMS TO A
HALF INCH IN OTHERS. THIS ACTIVITY WILL CONTINUE INTO EARLY THIS
EVENING.

AS OF 330 AM EDT THURSDAY...

THE NWS BLACKSBURG FORECAST AREA CONTINUES TO RESIDE IN A SOUPY AND
MOIST AIRMASS...WITH THE 00Z RNK AND GSO SOUNDINGS SHOWING PWAT/S
NEARLY 150% OF NORMAL. RESIDUAL INSTABILITY NORTH OF A WEAK SFC
FRONT CONTINUES TO HELP FIRE WIDELY SCATTERED SHOWERS AND STORMS
DURING THE PRE-DAWN HOURS.

THE SHORT RANGE MODELS ARE IN GOOD AGREEMENT THAT THE WEAK SFC
BOUNDARY TO OUR SOUTH THIS MORNING LIFTS NORTH AND WASHES OUT
TODAY...AS HEIGHTS ALOFT CLIMB. THIS WILL LEAVE OUR ENTIRE FORECAST
AREA AGAIN UNDER A VERY MOIST AIR MASS WITH THE GEFS FORECASTING
PWAT/S OVER 2 STANDARD DEVIATIONS ABOVE NORMAL IN THE EASTERN
PORTION OF OUR FORECAST AREA TODAY.

WITH FORECAST SOUNDINGS INDICATING SFC BASED CAPES BETWEEN 1000 AND
1500 J/KG AND LITTLE CONVECTIVE INHIBITION...WOULD EXPECT SCATTERED
SHOWERS AND STORMS TO AGAIN DEVELOP TODAY...AND EARLIER THAN
WEDNESDAY. PRECIPITATION SHOULD ALSO DEVELOP FARTHER NORTH AS THE
WEAK SFC BOUNDARY LIFTS NORTH THROUGH OUR REGION. LOCALLY HEAVY
RAINS AND THE POTENTIAL FOR URBAN FLOODING/FLOODING OF LOW LYING
AREAS IS POSSIBLE. BUT THE THREAT IS ISOLATED...AND STORMS SHOULD
MOVE AT 5-10 KTS BASED ON FORECAST SOUNDINGS.

TEMPS SHOULD BE SIMILAR TO YESTERDAY UNDER A MOSTLY CLOUDY
SKY...WITH A BLEND OF THE MAV/MET GUIDANCE USED.

SIMILAR TO WEDNESDAY NIGHT...EXPECT WIDELY SCATTERED SHOWERS AND
STORMS TO LINGER INTO THE OVERNIGHT HOURS TONIGHT AS CAPES 500-1000
J/KG PERSIST PER THE GFS. THE 21Z SREF ALSO IS MORE AGGRESSIVE WITH
DEVELOPING LOW CLOUDS AND FOG TONIGHT. THEREFORE...KEPT LOW TEMPS
CLOSER TO THE WARMER MAV GUIDANCE.

EVEN IF AN INSITU WEDGE DOES OVER TAKE THE AREA...IT WILL
BE SHALLOW WITH A CONSISTENT LIGHT SOUTHEASTERLY FLOW. WARM AIR
OVERRUNNING THIS WEDGE WILL KEEP THE CHANCE FOR LIGHT RAIN/DRIZZLE
AND FOG IN THE AREA INTO LATE TOMORROW MORNING. ONCE WE BREAK OUT
OF THE CLOUDS IN THE AFTERNOON...SOUTH-SOUTHEASTERLY FLOW WILL
BRING ANOTHER CHANCE FOR SHOWERS AND THUNDERSTORMS TO THE AREA.
AGAIN...STORMS WILL START ALONG THE BLUE RIDGE...THEN SPREAD OUT
FROM THERE. IF WE CAN HOLD AN EASTERLY WIND THROUGH
TOMORROW...TEMPERATURES SHOULD REMAIN IN THE 80S AREAWIDE.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/...
AS OF 415 AM EDT THURSDAY...

WHAT IS LEFT OF THE EARLY WEEK FRONTAL BOUNDARY APPEARS IN A VERY
DIFFUSE FASHION TO EXIST SOMEWHERE FROM SW VA INTO EAST CENTRAL
WV/WEST CENTRAL VA AT THE START OF THE PERIOD. A VERY
MOIST...UNSTABLE AIR MASS WILL REMAIN WITH TEMPERATURES AND
HUMIDITY LEVELS WELL ABOVE NORMAL FOR THIS TIME OF YEAR. GFS40
BUFKIT MODEL PWATS FRI-SAT ARE IN THE 1.9 TO 2.1 RANGE ACROSS THE
CWA...THUS NEAR ALL TIME MAX VALUES FOR THIS TIME OF YEAR. THIS
COMBINED WITH WELL ABOVE NORMAL TEMPERATURES WILL SUPPORT
CONTINUED SCATTERED PULSE-TYPE AFTERNOON CONVECTION. FOR FRI...THE
MOST FAVORED AREA APPEARS TO BE NEAR THE LINGERING FRONTAL
BOUNDARY/WEAK CONVERGENCE ZONE FROM SW VA NORTHEASTWARD TOWARD
CENTRAL VA. ALOFT...THERE IS LIMITED DYNAMICS THROUGH FRI AS A
BROAD SUBTROPICAL RIDGE REMAINS ACROSS THE REGION WITH 500MB
HEIGHTS IN EXCESS OF 590DM YET AGAIN. THE BIGGEST CONCERN FROM ANY
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO BE LOCALLY HEAVY RAIN
AND POTENTIALLY ISOLATED FLASH FLOODING WITH VERY WEAK STEERING
CURRENTS ALOFT. THIS WILL ESPECIALLY BE TRUE FRI AS THE BEST
POTENTIAL FOR CONVECTION SHOULD BE MORE INTO THE MOUNTAIN COUNTIES
AS OPPOSED TO THE FLATTER/PIEDMONT FOR TODAY. HOWEVER...THE LACK
OF SYNOPTIC/DYNAMIC FORCING PRECLUDES THE ISSUANCE OF ANY TYPE OF
HYDROLOGICAL PRODUCT AT THIS TIME.

BY SAT...A STRONG UPPER SHORT WAVE MOVING THROUGH THE GREAT LAKES
WILL PENETRATE THE UPPER RIDGE AND SUPPRESS IT ACROSS THE
SOUTHEAST STATES. THIS UPPER TROUGH WILL PUSH A FRONTAL SYSTEM
THROUGH THE REGION SAT-SUN. WITH VERY HIGH ANTECEDENT MOISTURE
AND ABOVE NORMAL TEMPERATURES...HENCE INSTABILITY...PRESENT IN
ADVANCE OF THE FRONTAL BOUNDARY...WIDESPREAD SHOWERS AND
THUNDERSTORMS SHOULD ACCOMPANY THE FRONT THROUGH THE REGION
SATURDAY/SATURDAY NIGHT. WIND FIELDS ALOFT ARE NOT PARTICULARLY
IMPRESSIVE AT THIS POINT...SO AGAIN THERMODYNAMICS AND ABUNDANT
MOISTURE ARE THE MAIN FEATURES IN PLAY. THUS...AGAIN THE MAIN
CONCERN WILL BE LOCALLY HEAVY RAINFALL AND POSSIBLY SOME GUSTY
WINDS WITH THE STRONGER CELLS...ESPECIALLY ANY LINEAR ORGANIZATION
THAT COULD DEVELOP ALONG THE FRONTAL BOUNDARY. CURRENTLY...SPC
DOES NOT INCLUDE THE REGION IN ANY TYPE OF SEVERE RISK...BUT WOULD
NOT BE SURPRISED IF A 5% RISK IS INTRODUCED WITH LATER OUTLOOKS AS
THE EVENT DRAWS NEARER. ALL- IN- ALL THE SITUATION APPEARS
SIMILAR TO THIS PAST TUESDAYS EVENT...ALBEIT THIS FRONT IS
DEFINITELY STRONGER THAN THE PREVIOUS ONE. TEMPERATURES FRI-SAT
SHOULD REMAIN WELL ABOVE NORMAL. HAVE FAVORED THE WARMER GFS MOS
FOR SAT ESPECIALLY ACROSS THE PIEDMONT. ONLY CLOUD COVER AND VERY
HIGH HUMIDITY LEVELS WILL KEEP MORE AREAS FROM REACHING THE LOW
90S...WHICH SHOULD GENERALLY BE CONFINED TO THE PIEDMONT...WITH
80S ELSEWHERE AND UPPER 70S IN THE MOUNTAINS.

SUPPORT FOR THE FRONT TO MOVE SOUTH OF THE REGION SUN IS ONLY
SLIGHTLY BETTER THAN WITH THE FRONTAL SYSTEM EARLIER THIS WEEK.
OVERALL...A BROAD RIDGE REMAINS ONLY TEMPORARILY SUPPRESSED ACROSS
THE SOUTHERN STATES AND THE FLOW ALOFT ACROSS OUR REGION AND THE
NORTHERN U.S. IS NEAR PURE ZONAL. PRECIPITATION WILL LIKELY NOT
CLEAR AND MOST LIKELY REDEVELOP ACROSS SOUTHERN SECTIONS OF THE
CWA SUN...THUS HAVE RETAINED GOOD CHC POPS GENERALLY SOUTH OF 460
AND INTO SW VA SUN AS A RESULT...WITH LOWER POPS NORTH. CLOUD
COVER AND SLIGHT CAA WILL RESULT IN MORE NORMAL TEMPERATURES FOR
THE SECOND HALF OF THE WEEKEND...ESPECIALLY AS 850MB TEMPS DROP
FROM THE CURRENT AND LATE WEEK +20C READINGS TOWARD MORE NORMAL
+16C READINGS FOR THIS TIME OF YEAR.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
AS OF 440 AM EDT THURSDAY...

AS NOTED ABOVE...A BROAD UPPER RIDGE REMAINS ACROSS THE SOUTHERN
U.S. AND IS POISED TO RETURN NORTHWARD THROUGH THE MID-PART OF THE
WEEK ONCE AGAIN. THUS...THERE DEFINITELY APPEARS TO BE SUPPORT
FOR THE FRONT TO STALL ONCE AGAIN TO THE SOUTH OF THE REGION...WITH
ATTENDANT MOISTURE AND PRECIPITATION TO REMAIN CLOSE AT HAND. THE
00Z ECMWF IS PARTICULARLY AGGRESSIVE WITH RETURN MOISTURE...BUT
BOTH THE GFS AND THE ECMWF SHOW DEEPER MOISTURE SURGING BACK INTO
THE REGION FROM THE SOUTHWEST LATE MON AS ANOTHER SHORT WAVE
TROUGH TRAVERSES THE REGION. A WEDGE ALSO DEVELOPS INTO THE REGION
EARLY NEXT WEEK...WHICH WOULD FURTHER DELAY ANY CLEARING OR DRYING
INTO THE REGION. THUS...CHC POPS REMAIN IN ORDER MOST AREAS
THROUGH THE PERIOD. THE BETTER FOCUS FOR CONVECTION UNTIL THE NEXT
FRONTAL SYSTEM ARRIVES MID OR LATE PART OF NEXT WEEK WILL BE
ACROSS THE SOUTHERN AND SOUTHWESTERN COUNTIES OF THE CWA...NEAREST
THE WEDGE BOUNDARY AND THE BETTER HEATING/INSTABILITY/MOISTURE.
THE WEDGE SHOULD HELP SUPPRESS CONVECTION SOME ACROSS NORTHEASTERN
PARTS OF THE CWA.

ECMWF/GFS BECOME CONSIDERABLY DISCREPANT WITH TIMING OF FUTURE
UPPER SHORT WAVES AND FRONTAL BOUNDARIES...SO HAVE MADE ONLY MINOR
CHANGES TO EXTENDED POPS. OVERALL...THE EXTENDED REMAINS WARM AND
UNSETTLED WITH CHC TO PERHAPS EVEN LIKELY POPS AS A POTENTIALLY
STRONGER FRONTAL SYSTEM AND UPPER SHORT WAVE MOVE INTO THE REGION
DURING THE LATER HALF OF THE WEEK.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
AS OF 215 PM EDT THURSDAY...

UNSTABLE...VERY MOIST ATMOSPHERE WILL PROMOTE DEVELOPMENT OF SCT-
NMRS SHRA/TSRA. THE ACTIVITY WILL TEND TO DRIFT NORTH WITH TIME.
HAVE INCLUDED VCTS FOR ALL TAF SITES FROM MID-AFTERNOON THROUGH
EARLY EVENING. A REPEAT OF LOW CLOUDS AND FOG WITH AREAS OF IFR-
LIFR CIGS/VSBYS CAN BE EXPECTED AGAIN FRI MORNING...ESPECIALLY IN
AREAS THAT RECEIVE RAIN LATE TODAY AND THIS EVENING. WINDS WILL
TREND TO LIGHT SSW SOUTH OF THE DIFFUSE BOUNDARY AND E-SE TO THE
NORTH...ESPECIALLY ACROSS THE PIEDMONT WHERE A VERY WEAK WEDGE
APPEARS EVIDENT.

MEDIUM CONFIDENCE IN CIGS AND VSBYS THROUGH THE TAF VALID PERIOD.
MEDIUM CONFIDENCE IN WIND DIR...HIGH CONFIDENCE IN LOW WIND SPD
THROUGH THE TAF VALID PERIOD.

EXTENDED AVIATION DISCUSSION...THE FRONT WASHES OUT COMPLETELY BY
FRI...BUT SCT-NMRS SHRA/TSRA ARE AGAIN EXPECTED FRI
AFTERNOON...ESPECIALLY ACROSS SW VA AND SE WV WHERE THE BETTER
CONVERGENCE WILL LINGER. A NEW FRONTAL SYSTEM AND UPPER TROUGH
APPROACH FROM THE NW BY SAT OR SUN WITH WIDESPREAD MORE ORGANIZED
CONVECTION SLATED TO IMPACT THE REGION FROM WEST TO EAST OVER THE
WEEKEND.
