NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Jun 12, 1:42 PM EST, 19 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 242 PM EDT SUN JUN 12 2011 .SYNOPSIS... A WEAK COOL FRONT WILL MOVE SOUTHEAST THROUGH THE MID APPALACHIAN AND MID ATLANTIC REGION TODAY...ACCOMPANIED BY WIDELY SCATTERED TO SCATTERED SHOWERS AND THUNDERSTORMS. SLIGHT COOLER AND DRIER AIR WILL SPREAD INTO THE AREA BEHIND THE FRONT TONIGHT INTO TUESDAY. && .NEAR TERM /THROUGH TONIGHT/... LATEST VISIBLE SATELLITE IMAGERY INDICATES THAT THE EARLY MORNING FOG BANKS HAVE BURNED AWAY FOR THE MOST PART...AND WE HAVE MOSTLY CLEAR SKIES ACROSS OUR REGION. LOW CLOUD COVER MOVING IN FROM THE WEST CONTINUES TO DIMINISH DUE TO THE DOWNSLOPE WIND DIRECTION. FARTHER TO THE NORTHWEST...A COLD FRONT CAN BE FOUND DRAPED FROM THE INDIANA KENTUCKY BORDER...THROUGH OHIO AND INTO WESTERN PENNSYLVANIA. THIS SOUTHWARD MOVING FRONT WILL TRIGGER ADDITION SHOWERS AND THUNDERSTORMS ACROSS OUR REGION DURING THE AFTERNOON. MADE A FEW UPDATES TO THE EARLY MORNING FORECAST PACKAGE. ADJUSTED AFTERNOON HIGHS A LITTLE UPWARD TO REFLECT THE DECREASED CLOUD COVER AND INCREASED HEATING WE CAN EXPECT FOR TODAY. ALSO... DECREASED RAIN CHANCES FOR THE REMAINDER OF THE MORNING. WITH NO BOUNDARIES EXPECTED TO MOVE INTO THE AREA WITHIN THE NEXT FEW HOURS TO TRIGGER THUNDERSTORM ACTIVITY...EXPECT THAT WE WILL SEE THE DEVELOPMENT BEGIN ALONG THE RIDGELINES DURING THE EARLY AFTERNOON. .PREVIOUS DISCUSSION... WEAK SHORT WAVE TROF LIFTING NORTHEAST THROUGH THE OHIO VALLEY WILL ALLOW WEAK COOL FRONT TO PROGRESS SOUTHEAST THROUGH THE BLACKSBURG FORECAST AREA THIS AFTERNOON INTO EARLY TONIGHT. AIR MASS AHEAD OF FRONT CONTINUES TO BE MOIST AND MARGINALLY UNSTABLE...WITH MOST UNSTABLE CONVECTIVE AVAILABLE POTENTIAL ENERGY EXPECTED TO ONCE AGAIN BE IN THE 1000-2000 J/KG RANGE ALONG WITH LIFTED INDEX VALUES IN -2 TO -4 RANGE DURING TIME OF PEAK HEATING. HOWEVER...UNLIKE PAST SEVERAL DAYS...LOWER TROPOSPHERIC WINDS WILL BE MORE FROM THE WEST TODAY...WHICH WILL INITIALLY SUPPORT DEVELOPMENT OF WIDELY SCATTERED TO SCATTERED SHOWERS/THUNDERSTORMS MAINLY WEST OF THE BLUE RIDGE THIS MORNING INTO EARLY AFTERNOON BEFORE STORMS TRANSITION TO CONVERGENCE/CONFLUENCE ZONE IN VICINITY OF DEEPENING LEE TROF EAST OF THE BLUE RIDGE DURING THE AFTERNOON AS WESTERLY WINDS SLOWLY INCREASE. WITH BEST COVERAGE OF STORMS EXPECTED TO BE NEAR THE LEE TROF DURING TIME OF BEST HEATING THIS AFTERNOON...BEST THREAT OF SEVERE WEATHER IN BLACKSBURG FORECAST AREA WILL LIKELY BE OVER SOUTHSIDE VA INTO NORTH CENTRAL NC...ALTHOUGH CAN NOT RULE OUT AN EARLIER MID MORNING TO EARLY AFTERNOON ISOLATED SEVERE STORM FURTHER WEST. COOL FRONT/LEE TROF EXPECTED TO MOVE SOUTHEAST AND OUT OF THE BLACKSBURG FORECAST AREA BY EARLY EVENING...SO OTHER THAN A LINGER LOW CHANCE OF A LINGERING EARLY EVENING SHOWER/STORM ALONG IN THE EXTREME SOUTHEASTERN COUNTIES...WEATHER FOR TONIGHT SHOULD BE DRY AS DRIER AND COOLER AIR FILTERS IN FROM THE NORTH AND WEST BEHIND THE FRONTAL SYSTEM. HIGH TEMPERATURES TODAY WILL BE LARGELY INFLUENCED BY CLOUD COVER AND PROXIMITY TO SHOWER/STORM OUTFLOW BOUNDARIES...BUT WITH TEMPERATURES GENERALLY SIMILAR TO THAT ON SATURDAY...MAINLY 80S IN THE MOUNTAINS AND LOWER 90S ACROSS THE PIEDMONT. ARRIVAL OF LOWER DEW POINTS AND CLEARING SKIES SHOULD SUPPORT TEMPERATURES FALLING BACK INTO THE 50S IN THE MOUNTAINS...WITH MAINLY LOWER 60S IN THE PIEDMONT TONIGHT. && .SHORT TERM /MONDAY THROUGH WEDNESDAY NIGHT/... COLD FRONT IS WELL SOUTH OF THE FORECAST AREA BY MONDAY...WITH HIGH PRESSURE BUILDING INTO THE REGION WITH A COOLER/DRIER AIR MASS. BIG SPREAD IN GUIDANCE TEMPS...WITH THE MAV 3 TO 5 DEGREES WARMER THAN THE MET IN MOST LOCATIONS. LOOKS LIKE THE STRONGER SURGE OF HIGH PRESSURE OCCURS TUESDAY NIGHT INTO WEDNESDAY BEHIND A STRONG VORT LOBE THAT ROTATES AROUND A DEEPENING UPPER LOW OFF THE NERN U.S. COAST...AND ACROSS THE FORECAST AREA BY TUE NIGHT. HAVE LEANED TEMPS TOWARD THE WARMER MAV GUIDANCE FOR HIGHS MONDAY...THEN TOWARD THE COOLER MET GUIDANCE FOR HIGHS TUE. MODELS ARE IN AGREEMENT IN SHOWING AN MCS DEVELOPING MON NIGHT IN RESPONSE TO A WEAKER SHORT WAVE AHEAD OF THE STRONG VORT LOBE. THIS MCS RIDES SOUTHEASTWARD ALONG THE FRONT...AND INTO THE SRN APPALACHIANS. THIS SHOULD NOT AFFECT MOST OF THE FORECAST AREA...BUT WITH FAIRLY GOOD AGREEMENT IN THE MODELS...FELT IT BEST TO ADD SOME LOW POPS TO THE SW MTNS OF VA AND NW MTNS OF NC TUE AFT INTO TUE NIGHT. MODELS ARE A LITTLE FASTER IN BRINGING THE OLD FRONT SOUTH OF THE FORECAST AREA NEWD AS A WARM FRONT ON WEDNESDAY IN RESPONSE TO THE NEXT UPSTREAM WAVE MOVG THRU THE UPPER MIDWEST AND DROPPING INTO THE TROUGH ALONG THE EAST COAST. I HAVE RAISED THE POPS SOME WED INTO WED NIGHT TO ACCOUNT FOR THIS FASTER MOVEMENT...AND ALSO LOWERED MAX TEMPS A FEW DEGREES FOR WED EXPECTING MORE CLOUD COVER AND POSSIBLE SHOWERS. && .LONG TERM /THURSDAY THROUGH SATURDAY/... HIGH PRESSURE AT THE SFC WILL BE OVER THE NE TUE NIGHT-WED WITH A TROF OFF THE EAST COAST. THIS WILL BE PROVIDING SOME COOLER WEATHER EARLY IN THE PERIOD. 00Z ECWMF/06Z GFS SEEM OUT OF PHASE MOST OF THIS PERIOD...BUT SHOW A STRONGER SHORTWAVE PUSHING INTO THE OHIO VALLEY BY 12Z/8AM THURSDAY. A FRONTAL BOUNDARY WILL BE PROGRESSING INTO THE OHIO VALLEY SOUTH INTO THE TENNESSEE VALLEY BY THIS TIME INCREASING THE CHANCES OF RAIN...WITH SFC HIGH OFF THE EAST COAST RETURNING THE FLOW AROUND TO THE SOUTHEAST AND SOUTH. UPPER LEVEL 5H PATTERN STAYS FASTER THIS PERIOD AND FLATTER SO TEMPS SHOULD BE ABOUT OR JUST BELOW NORMAL EARLY THEN AT OR ABOVE NORMAL BY SAT. THIS FRONT IS FORECAST BY HPC TO SHIFT EAST ACROSS THE FORECAST AREA THU NIGHT INTO FRIDAY THEN STALL JUST SOUTH OF THE CWA SAT. THIS LINES UP WITH A BLEND OF THE GFS/ECMWF AS THE GFS KEEPS THE FRONT ACROSS THE OHIO VALLEY/MID ATLANTIC WHILE THE ECMWF DROPS IT SOUTH. WITH THIS IN MIND WILL HOLD ONTO POPS FROM WED LATE AFTN THRU SAT WITH BEST CHANCE THU-FRI. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... KBCB AWOS OBSERVATIONS ARE NOT TRANSMITTING TO AWIPS SYSTEM...BUT INFORMATION CAN BE OBTAINED BY DIALING INTO THE SYSTEM. WILL REGULARLY CALL SYSTEM TO ASSURE THAT CURRENT TERMINAL FORECAST FOR THIS SITE REMAINS REPRESENTATIVE OF LOCAL WEATHER CONDITIONS. SHOWERS AND THUNDERSTORMS HAVE REDEVELOPED THIS AFTERNOON...MAINLY WEST OF THE BLUE RIDGE...AND ARE CURRENTLY IN THE VICINITY OF LWB... BCB...AND BLF. THESE STORMS WILL SPREAD EASTWARD THROUGH THE NEXT FEW HOURS...AND SHOULD BE AFFECTING ROA...LYH AND DAN BEFORE OR BY 12/21Z. MANY OF THESE STORMS ARE EXPECTED TO BE COMPACT IN NATURE... MEANING VERY HIT AND MISS ACTIVITY. EXPECT PERIODS OF VERY HEAVY BY BRIEF DOWNPOURS WHERE THE STORMS DO OCCUR...WHICH WILL DROP VISIBILITIES TO LESS THAN 1SM MILE. ALSO...THE ATMOSPHERE IS FAVORABLE FOR LOCALLY STRONG WINDS AND LARGE HAIL IN AND AROUND THE LARGER THUNDERSTORMS. THESE STORMS ARE EXPECTED TO PUSH EAST OF OUR REGION LATE THIS EVENING AS A COLD FRONT MOVES THROUGH. SKIES WILL CLEAR AND WINDS WILL BECOME NORTHWESTERLY BEHIND THE FRONT...WITH WIND SPEEDS EXPECTED TO BE LESS THAN 10KT. STILL LOOKING AT THE POSSIBILITY OF LOCALIZED FOG EARLY MONDAY MORNING...WHICH IS EXPECTED TO BURN OFF BY 13/13Z. VFR CONDITIONS ARE EXPECTED TO BE THE NORM THEREAFTER. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...NONE. NC...NONE.
