AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
749 PM EDT SAT JUL 17 2010

.SYNOPSIS...
A WEAK COLD FRONT WILL DRIFT SOUTH INTO THE AREA TONIGHT BEFORE
DISSIPATING. WEAK HIGH PRESSURE WILL SPILL INTO THE REGION SUNDAY
INTO SUNDAY NIGHT AHEAD OF ANOTHER WEAK COLD FRONT APPROACHING
FROM THE NORTHWEST. THIS FRONT SHOULD SAG SOUTHEAST TOWARD THE
AREA MONDAY INTO TUESDAY BRINGING A BETTER CHANCE OF SHOWERS AND
STORMS FOR EARLY IN THE WEEK.

&&

.NEAR TERM /THROUGH SUNDAY/...
HAVE UPDATED POPS REST OF TONIGHT TO FOCUS ON THE FAR WESTERN CWA-
THAT IS WHERE ALL THE REMAINING INSTABILITY IS. THUNDERSTORMS JUST
TO THE WEST OF THE CWA HAVE BEEN STRUGGLING TO MOVE EAST...SEEM TO
BE TRYING TO MOVE EAST...BUT MOSTLY RE-DEVELOPING ON THE WESTERN
RIDGES AND PROPAGATING SOUTHWARD. ANOTHER SMALLER CLUSTER OF
STORMS ARE MOVG NEWD TOWARD THE NRN NC MTNS AS WELL. HAVE LEFT THE
HIGHEST POP OUT TOWARD TAZEWELL AND SMYTH COUNTIES...AND ALSO NRN
NC MTNS THIS EVENING.

PREVIOUS DISCUSSION...
MAIN AXIS OF CONVECTION CONTINUES TO SHIFT SE INTO THE PIEDMONT
ALONG THE TRAILING TAIL OF THE CONVERGENCE BAND FROM THE WEAK MID
LEVEL S/W PASSING TO THE NORTH. EXPECT THIS AREA TO TAKE THE MAIN
LIFT OUT OF THE REGION THIS EVENING ESPCLY GIVEN DRYING ALOFT SEEN
ON WATER VAPOR TO THE WEST. COULD AGAIN SEE SOME REDEVELOPMENT OF
SHRA/TSRA EARLY THIS EVENING IN THE WEST WHERE HEATING MAY BE ABLE
TO REBOUND INSTABILITY GIVEN HIGH SFC THETA-E VALUES ATTM. OTRW
WEAK COLD FRONT TO THE NORTH WILL SHIFT SLOWLY SOUTH OVERNIGHT IN
THE WAKE OF THE EXITING S/W WITH ONLY THE GFS SHOWING ADDED SHRA
ACROSS THE NW WHICH LOOKS IFFY. THUS CUTTING POPS BACK TO CHANCE
EARLY ON AND SLIGHT POPS OVERNIGHT OR JUST DRY ESPCLY OUT EAST.

NEXT S/W ROUNDS THE UPPER RIDGE BY EARLY SUNDAY AND PASSES TO THE
NORTH LATER IN THE AFTERNOON. FRONT ASSOCIATED WITH THIS FEATURE
WILL AGAIN REMAIN WELL TO THE NW WHERE LOBE OF DEEPER RH AND LIFT
WILL RESIDE SUNDAY AFTERNOON. HOWEVER DECENT NW FLOW ALOFT OVERTOP
SOME AFTERNOON LOW LEVEL BACKING MAY BE ENOUGH TO SPARK AT LEAST
SCATTERED TSRA COVERAGE ESPCLY NW PER PROGGED CAPES AND ALONG THE
BLUE RIDGE. ELSW SINCE BASICALLY IN BETWEEN UVV SOURCES AND NOT
QUITE AS HOT APPEARS CONVECTIVE COVERAGE A BIT LESS ORGANIZED SO
BASICALLY CHANCE POPS FOR MORE SCATTERED NATURE FROM LATE MORNING
ON. DEWPOINTS REMAIN QUITE SOUPY TONIGHT WITH LOWS REMAINING AT OR
ABOVE 70 OUT EAST WITH MID/UPPER 60S WEST. GIVEN SLIGHTLY COOLER
85H TEMPS IN THE WAKE OF THE CURRENT WAVE...FOLLOWED CLOSER TO THE
LOWER MAV MOS FOR HIGHS ON SUNDAY WHICH STILL PUTS THE EAST INTO
THE 90-95 RANGE.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
A SURFACE COLD FRONT WILL SLOWLY PUSH SOUTHEAST ACROSS THE FORECAST
AREA INTO MONDAY NIGHT. WHILE SLIGHTLY ZONAL FLOW ALOFT WITH
EMBEDDED SHORTWAVES WILL BE PRESENT THROUGH THE SHORT TERM PERIOD.
THIS COMBINATION WILL ALLOW FOR SCATTERED SHOWERS AND THUNDERSTORMS
TO DEVELOP EACH DAY OVER THE FORECAST AREA. SOME CONVECTION WILL
CONTAIN MODERATE TO HEAVY RAIN IN LOCALIZED AREAS.

THE HOT AND HUMID AIRMASS WILL CONTINUE OVER THE FORECAST AREA
ALLOWING MAX AND MIN TEMPERATURES TO RUN ABOVE SEASONAL NORMS
THROUGH THE PERIOD.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
MODELS SUGGESTS AN UPPER RIDGE OVER THE SOUTHEASTERN STATES BEING
SUPPRESSED AS SHORTWAVES RIDE ALONG ITS NORTHERN PERIPHERY. WHILE AT
THE SURFACE...HIGH PRESSURE SLOWLY WEAKENS THROUGH THE END OF THE
WEEK. THESE WILL AID IN UNSETTLED WEATHER IMPACTING THE COUNTY
WARNING AREA THROUGH MOST OF THE EXTENDED PERIOD. MODELS PROG
ANOTHER COLD FRONT PUSHING DOWN FROM THE NORTHWEST BY THE WEEKEND.

THE HOT AND HUMID AIRMASS WILL PERSIST OVER THE FORECAST AREA
LEADING TO BOTH MAX AND MIN TEMPERATURES TO REMAIN ABOVE SEASONAL
NORMS THROUGH THE EXTENDED.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
CONVECTION HAS MOVED SOUTH OF THE AREA...AND MOST OF THE AREA HAS
BECOME STABLE WITH ONLY A SLIGHT CHC OF ANY ADDITIONAL TSTMS.
HOWEVER...THE FAR WEST RECEIVED ENOUGH HEATING TO DE-STABILIZE
AGAIN. THERE IS A CHANCE THAT BLF WILL SEE A TSTM THROUGH ABOUT
04Z...BUT I THINK LOW ENOUGH THAT I DID NOT INCLUDE IN THE TAF.

STILL LOOKS THERE WILL BE AREAS OF MVFR FOG DEVELOP AFTER THE
WIDESPREAD RAIN...BUT ENOUGH DEBRIS CLOUDS AND LOW LEVEL MIXING TO
PREVENT ANY WIDESPREAD IFR FOG. LWB WILL HAVE THE BEST CHC OF
SEEING IFR FOG...AND I HAVE TAKEN THEM DOWN FOR A FEW HOURS AROUND
18/12Z.

YET ANOTHER UPPER LEVEL DISTURBANCE WILL SWING ACROSS THE AREA SUN
AFTERNOON...AND SHOULD HELP GENERATE AT LEAST SCT TSTMS. BEST CHC
LOOKS TO BE IN THE MTNS WITH MORE OF A WEST FLOW...SO HAVE
INCLUDED VICINITY TSTMS IN THE BLF AND LWB TAFS. HAVE JUST ADDED
IN CB TO THE ROA...LYH AND DAN TAFS SUN AFTERNOON.

THE WX PATTERN THROUGH THURSDAY FAVORS CHANCES OF SHOWERS/STORMS
AS WEAK FRONTS SHIFT ACROSS THE OHIO VALLEY INTO THE MID ATLANTIC
WITH BERMUDA HIGH OVER THE SOUTHEAST. WITH ANY TSRA EXPECT SUB VFR
CONDITIONS. POTENTIAL FOR FOG AT NIGHT EXISTS AS WELL AT
LYH/DAN/LWB.
