AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
1218 PM EDT SAT APR 16 2011

.SYNOPSIS...
A STRONG STORM SYSTEM WILL PUSH A COLD FRONT THROUGH THE AREA
TODAY. AFTER A BRIEF COOL DOWN SUNDAY...WARMER WEATHER RETURNS ON
MONDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
THIS LATEST UPDATE IS BEING MADE TO REFLECT THE CANCELLATION OF
THE HIGH WIND WARNING IN THE EXTREME WESTERN TIER OF COUNTIES IN
THE FORECAST AREA...AND THAT THE WIND ADVISORY HAS BEEN EXTENDED
FURTHER TO THE EAST...AND WILL CONTINUE THROUGH 4 PM SUNDAY
AFTERNOON.

A TORNADO WATCH HAS ALSO BEEN ISSUED THROUGH 9 PM THIS EVENING FOR
MUCH OF THE NORTH CAROLINA PIEDMONT AND SOUTHSIDE VIRGINIA...
ALTHOUGH THE LINE OF STRONGEST THUNDERSTORM ACTIVITY WILL HAVE
CLEARED OUR FORECAST AREA TO THE EAST BY EARLY EVENING.

./PREVIOUS DISCUSSION ISSUED AT 1026 AM/...
LITTLE CHANGE FROM THE PREVIOUS FORECAST PHILOSOPHY THIS
MORNING... AND AM STILL KEEPING AN EYE ON A STRONG SHORT WAVE OVER
WESTERN KENTUCKY...WHICH IS WRAPPING AROUND THE MAIN UPPER LOW.
STILL BELIEVE THIS SHORTWAVE WILL HELP INTENSIFY THE SHOWER AND
THUNDERSTORM ACTIVITY ACROSS OUR AREA DURING THE EARLY
AFTERNOON...ESPECIALLY ACROSS THE NORTH CAROLINA PIEDMONT AND
SOUTHSIDE VIRGINIA. THE COLD FRONT HAS ENTERED EXTREME WESTERN
KENTUCKY AND IS MAKING STEADY PROGRESS TOWARD OUR WESTERN TIER OF
COUNTIES...MANY OF WHICH HAVE RECEIVED AT LEAST 2 INCHES OF
RAIN...AND SOME WHICH HAVE RECEIVED IN EXCESS OF 4 INCHES. ONCE
THE FRONT MOVES THROUGH...RAINFALL WILL DIMINISH ALTHOUGH A FEW
SHOWERS WILL REMAIN.

LATEST FORECAST UPDATE MADE BASICALLY TO LOWER TODAYS HIGH TEMPERATURES
A FEW DEGREES EAST OF THE BLUE RIDGE. THICK CLOUD COVER AND SHOWER
ACTIVITY WILL KEEP TEMPERATURES FROM LIFTING INTO THE UPPER 60S TO
NEAR 70 AS PREVIOUSLY THOUGHT. CIRRUS BLOWOFF FROM CONVECTION TO
OUR SOUTH SHOULD FILL THE HOLES WHICH DEVELOP IN THE LOWER CLOUD
COVER ACROSS OUR REGION. HOWEVER...IF ANY HOLES DO DEVELOP IN THE
CLOUDS FOR AN EXTENDED PERIOD OF TIME...EXPECT SURFACE TEMPERATURES
WILL SPIKE UPWARD 4 TO 6 DEGREES OVER A SHORT PERIOD OF TIME.

./PREVIOUS DISCUSSION ISSUED AT 747 AM/...
A COMPLEX...POTENT STORM SYSTEM CONTINUES TO MOVE ACROSS THE
MIDWEST. WATER VAPOR SHOWS THE MAIN UPPER LOW LIFTING NE INTO
ILL...BUT WITH MORE STRONG SHORT WAVES ROTATING AROUND THE LOW. ONE
STRONG WAVE...IN PARTICULAR...IS DIGGING SEWD TOWARD THE TN
VALLEY. THIS WAVE...AND ASSOCIATED JET MAX...WILL RE- ENERGIZE A
LINE OF SHOWERS/TSTMS ALONG THE SFC FRONT LATER THIS MORNING. THIS
LINE WILL THEN SWEEP EAST ACROSS THE FORECAST AREA.
MEANWHILE...AHEAD OF ANY CONVECTION ASSOCIATED WITH THE SFC
FRONT...WE ARE GETTING SOME HEAVY RAINFALL ALONG THE BLUE RIDGE IN
A VERY STRONG SOUTHEAST FLOW. PARTS OF WATAUGA COUNTY HAVE ALREADY
GOTTEN OVER 2 INCHES...AND THIS UPSLOPE MODERATE TO HEAVY RAIN
WILL CONTINUE WITH HOURLY RATES OF .25 TO .50...UNTIL THE FRONT
MOVES THROUGH. NEEDLESS TO SAY...THIS POSES A GENERAL FLOOD THREAT
JUST WITH THE UPSLOPE RAIN...BUT IF A LINE OF CONVECTION MOVES
THROUGH AS EXPECTED...IT WOULD POSE A SIGNIFICANT FLASH FLOOD
THREAT...WITH PWATS OF 1.25 INCHES OR HIGHER.

NOW THAT RAIN AND LOWER CLOUDS HAVE SPREAD INTO THE FORECAST
AREA...IT WILL BE HARDER TO GET STRONG WIND GUSTS TO THE
SFC...BUT THE STRONGEST LOW LEVEL JET OCCURS FORM ABOUT 500 AM
THROUGH 800 AM...SO WILL CONTINUE THE HIGH WIND WARNING AND
WIND ADVISORIES WHERE THEY ARE ALREADY IN EFFECT. LOOKING FOR
STRONGER GUSTS MAINLY IN ELEVATIONS ABOVE 3000 FEET...AND ALSO
THE CLINCH/HOLSTON VALLEY AND ADJACENT MTNS WHERE THEY GET THE
MTN WAVE EFFECT WITH A SOUTHEAST WIND. WILL PROBABLY BE ABLE TO
DROP THE WIND HEADLINES BEFORE NOON.

FINALLY...WE ARE STILL LOOKING AT A SEVERE TSTM THREAT WITH DAMAGING
WINDS AND POSSIBLE ISOLATED TORNADOES. THINK THE AREA WILL REMAIN
CLOUDY SO SURFACE BASED INSTABILITY WILL NOT BE MUCH. IT STILL LOOKS
LIKE A LOW CAPE/HIGH SHEAR ENVIRONMENT THAT WOULD SUPPORT LINEAR
BANDS OF TSTMS WITH A DAMAGING WIND THREAT...AND POSSIBLE
TORNADOES. THE MODERATE RISK FOR SVR NOW EXTENDS RIGHT UP TO
DANVILLE...CLIPPING OUR FAR SOUTHEAST CWA. FOLKS WHO LIVE FROM
MARTINSVILLE EAST TO SOUTH BOSTON SOUTH INTO THE NC PIEDMONT WILL
STILL NEED TO BE ALERT MAINLY THIS AFTERNOON FOR SVR WX. THIS IS
MENTIONED IN THE HWO. THE REST OF THE CWA WILL HAVE A THREAT OF
STRONG DAMAGING WIND GUSTS WITH ANY AS IT MOVES THROUGH.

MADE ONLY MINOR ADJUSTMENTS TO HIGH TEMPS TODAY WITH CLOUD COVER
MUCH OF THE DAY.

BEHIND THE FRONT TONIGHT...THERE IS FAIRLY STRONG COLD
ADVECTION...WITH 850 MB TEMPS DROPPING TO AROUND -2C IN THE MTNS.
IN ADDITION 6 HOUR PRESSURE RISES ARE AROUND 6 MBS...WITH 850 MB
WINDS AROUND 450 KNOTS FROM THE WEST. I HAVE INCLUDED WIND GUSTS
OF UP TO 50 MPH IN THE MTNS ALONG THE BLUE RIDGE IN FAR SW VA AND
NW NC. WE WILL LIKELY NEED ANOTHER WIND ADVISORY TONIGHT FOR THE
WEST WINDS BEHIND THE FRONT. I ADJUSTED LOW TEMPS CLOSER TO THE
COLDER MET GUIDANCE...WITH HIGH ELEVATIONS IN THE MTNS DROPPING TO
AROUND 32 DEGREES.

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
HIGH PRESSURE SLIDES QUICKLY EASTWARD ON SUNDAY FROM THE LOWER
PLAINS INTO THE SOUTHEAST UNITED STATES. AS THE HIGH PUSHES EAST
OF THE SOUTHERN APPALACHIANS SUNDAY AFTERNOON...OUR WINDS WILL
BECOME INCREASINGLY SOUTHWESTERLY...WHICH WILL BRING AN END TO ANY
RESIDUAL SHOWERS ACROSS THE WESTERN HALF OF THE FORECAST AREA.
STRONG WARM ADVECTION AND CLEARING SKIES DURING THE AFTERNOON
SUNDAY WILL ALLOW TEMPERATURES TO REBOUND NICELY...WITH HIGHS
RANGING FROM THE LOWER 60S IN SOUTHEAST WEST VIRGINIA...TO THE
LOWER 70S IN THE NORTH CAROLINA PIEDMONT.

MONDAY WILL PROVIDE OUR REGION ANOTHER DAY TO DRY OUT FROM SATURDAYS
HEAVY RAINS...WITH A CONTINUED SOUTHWEST FLOW AND WARM ADVECTION.
WIND SPEEDS FROM THE SOUTH AND SOUTHWEST WILL ALSO GRADUALLY
INCREASE DURING THE AFTERNOON AS THE PRESSURE GRADIENT TIGHTENS
BETWEEN HIGH PRESSURE OVER THE ATLANTIC...AND A DEVELOPING LOW
PRESSURE SYSTEM OVER THE PLAINS. LOOK FOR WARMER HIGH
TEMPERATURES ON MONDAY...WITH HIGHS RANGING THROUGH THE 70S. SPOTTY
SHOWER ACTIVITY WILL INCREASE LATE MONDAY NIGHT AND THE EARLY
MORNING HOURS OF TUESDAY IN THE CENTRAL APPALACHIANS AS A WARM
FRONT MOVES INTO THE OHIO RIVER VALLEY.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
LONG RANGE WEATHER FORECAST MODELS ARE IN AGREEMENT THAT TUESDAY
STARTS OFF WITH A WARM FRONT STRETCHING UP THE OHIO RIVER VALLEY
THROUGH WEST VIRGINIA. HOWEVER...MODEL DISAGREE SOMEWHAT AS TO THE
EXACT PLACEMENT OF THE WARM FRONT...WITH THE GFS MODEL INDICATING
THAT THE FRONT WILL BE NORTH OF OUR REGION...WHILE THE ECMWF MODEL
DRAPES THE FRONT ACROSS THE ALLEGHANY HIGHLANDS. BELIEVE THE WARM
FRONT WILL BE A LITTLE NORTH OF OUR REGION...BUT STILL CLOSE ENOUGH
TO PROVIDE FOCUS FOR SPOTTY SHOWERS AND THUNDERSTORMS NORTH OF
INTERSTATE 81 DURING TUESDAY MORNING AND AFTERNOON. SHOWER AND
THUNDERSTORM ACTIVITY WILL DIMINISH DURING THE LATE AFTERNOON AS THE
BOUNDARY CONTINUES NORTHWARD TOWARD THE GREAT LAKES.

SHOWERS AND THUNDERSTORMS INCREASE AGAIN WEDNESDAY AFTERNOON AND
EVENING AS A DEEP LOW PRESSURE SYSTEM CROSSES THE GREAT LAKES...
DRAGGING A COLD FRONT IN ITS WAKE. AS THE COLD FRONT APPROACHES...
THE COMBINATION OF AFTERNOON SURFACE TEMPERATURES IN THE UPPER 70S
TO LOWER 80S...AND A MODERATELY UNSTABLE ATMOSPHERE...WILL SET US UP
ONCE AGAIN FOR ANOTHER ROUND OF STRONG TO SEVERE STORMS. THESE
STORMS WILL BE CAPABLE OF STRONG WINDS...LARGE HAIL...AND ISOLATED
TORNADOES. THE COLD FRONT MOVES VERY CLOSE TO OUR REGION EARLY
THURSDAY MORNING...AND BECOMES STATIONARY FOR THE NEXT FEW DAYS. THE
LOCATION OF THE BOUNDARY WILL BE IMPORTANT TO KEEP AN EYE AS WE
APPROACH CLOSER IN TIME...AS THE SOUTH SIDE OF THE BOUNDARY WILL BE
WHERE THE BEST CHANCES OF SEVERE THUNDERSTORM ACTIVITY MAY BE FOUND
ON THURSDAY AND FRIDAY AFTERNOONS. THE BOUNDARY LIFTS NORTHWARD
AGAIN LATE FRIDAY EVENING AS A WARM FRONT...IN ADVANCE OF ANOTHER
LOW PRESSURE SYSTEM MOVING THROUGH THE GREAT LAKES ON SATURDAY.

&&

.AVIATION /16Z SATURDAY THROUGH WEDNESDAY/...
UPSLOPE MODERATE TO HEAVY RAIN CONTINUES ALONG AND EAST OF THE
BLUE RIDGE THIS MORNING...THE HEAVIEST SPREADING NORTHEAST ALONG
THE BLUE RIDGE IN SW VA. SHOWERS ALSO CONTINUE ACROSS THE REST OF
THE FORECAST AREA. FOR THE MOST PART...CIGS AND VSBYS ARE
MVFR...WITH OCNL IFR ALONG AND EAST OF THE BLUE RIDGE. HEAVIER
RAIN THRU THE MORNING WILL MAINLY AFFECT ROA AND LYH. A STRONG
LOW LEVEL JET WILL REMAIN AN AVIATION CONCERN THRU THE MORNING.
SFC GUSTS HAVE DIMINISHED MOST LOCATIONS...BUT WINDS AS STRONG AS
45 TO 50 KNOTS WILL BE WITHIN 2000 FT OF THE SFC...ESPECIALLY IN
THE MTNS. THIS WILL PRODUCE A STRONG LOW LEVEL WIND
SHEAR...LASTING THRU 100 AM TO NOON.

AS A SLOW MOVING STRONG COLD FRONT MOVES THROUGH THE REGION
BEGINNING AROUND NOON IN THE FAR WESTERN MTNS...AND EXITING EAST
OF DANVILLE AFTER 400 PM...ONE OR MORE LINES OF STRONG CONVECTION
WILL BE MOVING ACROSS THE FORECAST AREA. THIS CONVECTION WILL HAVE
VERY HEAVY DOWNPOURS...STRONG TO SEVERE WIND GUSTS...AND THERE IS
A POTENTIAL FOR TORNADOES IN THE PIEDMONT. DANVILLE HAS THE
GREATEST THREAT FOR TSTMS...SO I HAVE KEPT VCNTY TSTMS TO THE
DANVILLE TAF.

VFR RETURNS BY THIS EVENING EAST OF THE MTNS BEHIND THE FRONT
WITH A DOWNSLOPE WEST WIND. WESTERN SLOPES OF THE MTNS WILL SEE
LOWERING CIGS AND VSBYS HEADING INTO TONIGHT WITH A MOIST UPSLOPE
FLOW. HIGHER ELEVATIONS ALONG THE BLUE RIDGE WILL SEE WIND GUSTS
UP TO 50 MPH TONIGHT FROM THE WEST WINDS BEHIND THE FRONT.

VFR RETURNS TO ALL AREAS SUNDAY AND CONTINUES INTO TUESDAY WITH
HIGH PRESSURE ACROSS THE REGION BEHIND THE FRONT. ANOTHER FRONTAL
BOUNDARY MAY IMPACT THE AREA LATE TUESDAY BRINGING POTENTIAL MVFR
CONDITIONS TO THE MOUNTAINS BY LATE IN THE DAY.

&&

.HYDROLOGY...
WILL HAVE TO WATCH FLASH FLOOD POTENTIAL ALONG AND EITHER SIDE OF
THE BLUE RIDGE WEST INTO THE MTNS OF SE WV. UPSLOPE ENHANCEMENT
INTO THE BLUE RIDGE WILL BRING 1 TO 2 INCHES OF RAIN INTO THIS
MORNING...WITH THE SRN BLUE RIDGE FROM BOONE/BLOWING ROCK NORTH
INTO FLOYD COUNTY VA LIKELY RECEIVING 2+ INCHES. IF A LINE OF
CONVECTION WITH HEAVY DOWNPOURS MOVES THROUGH AHEAD OF THE SFC
FRONT AS EXPECTED...IT WILL POSE A SIGNIFICANT FLASH FLOOD THREAT.
IN ADDITION...WITH SATURATED SOILS IN THE STEEPER
TERRAIN...MUDSLIDES WILL ALSO BE A CONCERN.

BEYOND THE FLASH FLOODING...MAIN STEM RIVERS WILL ALSO NEED TO BE
MONITORED FOR RISES SAT AFTN INTO MONDAY. THERE IS A POTENTIAL FOR MINOR
TO MODERATE FLOODING ALONG PARTS OF THE JAMES...GREENBRIER AND DAN RIVERS.
