NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Jun 21, 6:37 PM EST, 1 hour 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 737 PM EDT MON JUN 21 2010 .SYNOPSIS... A STRONG HIGH PRESSURE ALOFT WILL MAINTAIN ITS GRIP OVER MUCH OF THE SOUTHERN HALF OF THE NATION FOR THE NEXT SEVERAL DAYS. THIS WILL KEEP THE FORECAST AREA HOT AND MAINLY DRY. HOWEVER...THE UPPER RIDGE IS EXPECTED TO GRADUALLY WEAKEN THROUGH THE WEEK...ALLOWING AN INCREASING CHANCE FOR A COOL FRONT AND ASSOCIATED SHOWER AND THUNDERSTORM ACTIVITY TO AFFECT THE REGION. && .NEAR TERM /THROUGH TUESDAY/... ANOTHER UPDATE TO UP POPS FARTHER EAST WITH STORMS CONTINUING TO REDEVELOP JUST WEST OF THE BLUE RIDGE IN VIRGINIA ALONG AXIS OF MOISTURE TRANSPORT. STILL THINK GIVEN WEAK RIDGING AND LACK OF UPPER SUPPORT THAT WILL SEE SHRA QUICKLY DIMINISH WITH LOSS OF HEATING. PREVIOUS DISCUSSIONS BELOW... QUICK UPDATE TO RAISE POPS TO HIGH CHANCE ACROSS SE WVA AND FAR WESTERN VA FOR LEADING EDGE OF MCS APPROACHING FROM THE NW. ALTHO MESO ANALYSIS SHOWS FADING SUPPORT...MOMENTUM AND COLD POOL ALOFT LIKELY TO KEEP THE BAND OF STORMS GOING A BIT LONGER. ALSO OUTFLOW MAY DEVELOP STRONGER CELLS AHEAD OF THE MAIN BAND SO MAY HAVE TO EXTEND POPS FARTHER SE INTO NW NC IF TRENDS CONTINUE. MAIN FCST ISSUE IN THE SHORT TERM IS THE UPSTREAM MCS MOVG INTO ERN KY AT THIS TIME. THE MEAN WIND FAVORS BRINGING THE SHOWERS/TSTMS INTO THE FAR WESTERN CWA...WHILE THE STRONGEST INSTABILITY REMAINS WELL WEST OF THE CWA. THE 12Z OP NAM BRINGS THE CONVECTION TO THE SW MTNS OF VA AND NRN MTNS OF NC...AND SO DOES OUR LOCAL 15Z RUN WRF-ARW MODEL...IN THE 6 PM TO 900 PM TIME FRAME. THE AIRMASS REMAINS VERY WARM AND FAIRLY DRY OVER MOST OF THE CWA. HAVE DECIDED TO ADD IN A SLIGHT CHC POP AT THIS TIME... THINKING THAT THE CONVECTION WILL LIKELY STAY WEST OF THE CWA WITH THE BETTER INSTABILITY. SHOULD BE ANOTHER WARM NIGHT...BUT WITH DECENT RADIATIONAL COOLING...SO HAVE KEPT LOWS CLOSER TO THE COOLER MAV GUIDANCE AND ADDED IN FOG TO THE MTN VALLEYS. FOR TUESDAY...THE AIRMASS BECOMES MORE UNSTABLE IN THE WAKE OF THIS EVENINGS MCS. THE WARMER TEMPS AROUND 700 MBS DROP SOME AND WE LOSE OUR STRONG MID LEVEL CAP. LOW LEVEL FLOW REMAIN WEAK...BUT IS WESTERLY INTO THE MTNS...AND SOUTH OR SOUTHWEST EAST OF THE MTNS...PROVIDING SOME CONVERGENCE ALONG THE BLUE RIDGE. IN ADDITION...ALL MODELS HAVE A SHORT WAVE MOVG THRU THE OHIO VALLEY AND CENTRAL APPLNS TUE AFTERNOON...AND THE TAIL END OF THIS FEATURE MAY HELP ORGANIZE TSTMS ACROSS THE NRN CWA. HAVE RAISED POPS TO LOW CHC FOR TUE AFT FROM THE BLUE RIDGE WESTWARD INTO THE MTNS. WILL BE ANOTHER HOT DAY...WITH TEMPS EVEN WARMER THAN TODAY. GUIDANCE SUGGESTS BLF BLF WILL HAVE A GOOD CHC TO REACH 90...WHICH WOULD TIE THEIR RECORD. ALL OTHER RECORDS LOOK OUT OF REACH. SEE CLIMATE SECTION BELOW FOR RECORD HIGHS TUE. FINALLY...WILL ISSUE AN AIR QUALITY ALERT FOR THE NE PIEDMONT OF NC FOR TUE. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... SHORTWAVE GOES BY JUST NORTH OF THE COUNTY WARNING AREA WHICH WILL RESULT IN LINGERING SHOWERS/THUNDERSTORMS FOR SOUTHEAST WEST VIRGINIA AND THE ALLEGHANY HIGHLANDS TUESDAY NIGHT. AT THIS TIME...HAVE MAINTAINED THE SLIGHT CHANCE POPS EARLY TUESDAY NIGHT AS EXPECT THE COVERAGE AREA TO STAY SMALL. PRECIP CHANCES WILL INCREASE THROUGH THURSDAY AFTERNOON TO LATE EVENING AS A SHORTWAVE TROUGH APPROACHES THE AREA. WILL HAVE MAINLY AFTERNOON AND EVENING ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS MAINLY ACROSS THE MOUNTAINOUS AREAS THROUGH WEDNESDAY WITH GREATER COVERAGE FOR THURSDAY. MAX TEMPERATURES EACH DAY WILL BE MAINLY THE MID TO UPPER 80S IN THE MOUNTAINS AND LOW TO MID 90S EAST OF THE BLUE RIDGE. LOWS WILL RANGE FROM THE LOW TO MID 60S WEST TO UPPER 60S TO NEAR 70 EAST. && .LONG TERM /FRIDAY THROUGH MONDAY/... CLOSED UPPER LOW SLOWLY PUSHES EAST BUT BEGINS TO BREAK DOWN BY LATE WEEK AS MORE SHORTWAVE ENERGY CROSSES THE GREAT LAKES. THIS WILL ALLOW A COLD FRONT TO PUSH TOWARDS THE FORECAST AREA. VERY LITTLE CHANGES TO THE LONG TERM FORECAST AS THE MODELS CONTINUE TO DISAGREE ON STRENGTH AND TIMING OF THE COLD FRONT. CONTINUE VARYING SLIGHT CHANCE TO CHANCE POPS EACH DAY THROUGH THE WEEKEND. PWATS ARE STILL PROGGED TO BE CLOSE TO 2 INCHES AND AT THIS TIME...EXPECT BEST CONVECTION TO BE AROUND THE FRIDAY AFTERNOON TIME FRAME. TEMPERATURES WILL REMAIN ABOVE SEASONAL NORMS THROUGH THE PERIOD. && .AVIATION /23Z MONDAY THROUGH SATURDAY/... ONGOING CONVECTION AROUND THE KBLF VICINITY AND POINTS SOUTH SHOULD REMAIN CONFINED TO THAT REGION THRU EARLY THIS EVENING BEFORE SLOWLY FADING. COULD SEE AN ISOLATED SHRA/TSRA DEVELOP OUT TOWARD KROA OTRW WILL BE LEAVING OUT ANY RESTRICTIONS DUE TO SHOWERS ELSW THIS EVENING. STILL APPEARS THAT KBLF COULD EXPERIENCE ANOTHER HOUR OR SO OF MVFR IN SHRA AND PERHAPS BRIEFLY IFR IF A HEAVIER DOWNPOUR MOVES ACROSS. OTRW HIGH PRESSURE IN PLACE WILL RESULT IN LIGHT WINDS AND MOSTLY CLEAR SKIES LATER TONIGHT...THINK THERE WILL BE FAIRLY WIDESPREAD GROUND FOG...ESPCLY IN THE WEST WHERE RAIN IS OCCURRING. THIS WILL LIKELY BRING MVFR VSBYS TO ALL TAF SITES EXCEPT FOR KROA UNLESS THEY SEE AN ISOLATED SHRA IN THE NEXT COUPLE OF HOURS. LWB WILL LIKELY SEE VLIFR RIVER FOG. FOG SHOULD BE SHALLOW ENOUGH THAT IT WILL LIFT BY 10 AM TUESDAY. ANOTHER IMPULSE WILL TRACK NORTH OF THE REGION LATER TUESDAY WITH THE POTENTIAL TO SEE ANOTHER MCS BAND OF CONVECTION TURN THE CORNER AND DROP SE INTO PARTS OF THE REGION. HOWEVER FLOW WILL BE QUITE UNIFORM FROM THE WEST/NW WHICH SHOULD LIMIT COVERAGE HEADING SE OFF THE MOUNTAINS. LATEST LOCAL WRF SHOWS THIS AXIS OF STORMS FROM KLWB TO AROUND KLYH LATE IN THE DAY SO WILL INCLUDE VCTS/CB MENTION THERE AND CB AT ALL EXCEPT KDAN FOR NOW. BEYOND 24 HOURS...PREDOMINANTLY VFR WEATHER WITH UNRESTRICTED CONDITIONS ARE EXPECTED AT ALL BLACKSBURG TERMINAL FORECAST SITES (KROA...KLYH...KDAN...KBLF...KLWB) THROUGH THE UPCOMING WEEK...WITH THE EXCEPTION OF A BRIEF PERIOD OF LOCALIZED LATE NIGHT/EARLY MORNING FOG. IN ADDITION...THERE WILL ALSO BE A LOW THREAT FOR BRIEF RESTRICTIONS IN VICINITY OF ISOLATED TO SCATTERED MAINLY DIURNALLY DRIVEN SHOWERS/THUNDERSTORMS WEDNESDAY. ANOTHER WEAK COOL FRONT WILL DIVE IN FROM THE NW THURSDAY BEFORE STALLING OR WASHING OUT BY WEEKS END. THIS MAY BRING A BETTER SHOT AT SEEING MORE CONVECTIVE COVERAGE ESPCLY LATE THU AND ACROSS THE SOUTH FRIDAY. && .CLIMATE...
