AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 152 PM EDT THU MAY 12 2005 .AVIATION... SCATTERED THUNDERSTORMS ARE DEVELOPING ALONG A PREFRONTAL TROUGH THIS AFTERNOON ACROSS SOUTH SIDE VIRGINIA. OTHER MORE ISOLATED STORMS ARE DEVELOPING IN THE HIGHER TERRAIN IN SOUTHWEST VIRGINIA AND NORTHWEST NORTH CAROLINA. THUNDERSTORMS SHOULD BECOME MORE NUMEROUS HEADING INTO LATE AFTERNOON/EARLY EVENING. BEST CHANCE FOR A THUNDERSTORM WILL BE AT THE DAN AIRPORT. LITTLE OR NO CHCANCE FOR LWB. ALL SITES SHOULD SEE AN END TO SHOWER ACTIVITY AND TSTMS IN THE VICINITY BY LATE EVENING. WITH A NE TO SE FLOW AND PLENTY OF LOW LEVEL MOISTURE...THINK CIGS AND VSBYS WILL LOWER TO MVFR MOST SITES OVERNIGHT. && .PREVIOUS DISCUSSION... (ISSUED 1027 AM EDT THU MAY 12 2005) SHORT TERM (REST OF TODAY)... MODIFIED 12Z SOUNDINGS SHOW MODERATE INSTABILITY BY LATE AFTERNOON IN THE PIEDMONTS OF SW VA AND NW NC. WILL BE WEAK SHEAR THOUGH...AND NO UPPER LEVEL FORCING TO SPEAK OF. HOWEVER...THE SFC FNT CURRENTLY ACROSS MD AND EXTREME NRN VA IS STILL PROGGED TO MOVE BACK DOOR STYLE INTO THE CWA THIS AFTERNOON. THIS SHOULD PROVIDE ENOUGH SFC CONVERGENCE ARND PEAK HEATING TO PRODUCE SCT TO NUMEROUS TSTMS ALONG THE BOUNDARY. WITH MOISTURE POOLING AHEAD OF THE FNT...MODEL PWS INCREASE TO AROUND 1.5 INCHES IN THE PIEDMONT LATE THIS AFT. THIS IS 150% OF NORMAL. IN ADDITION...STROMS WILL BE SLOW MOVING AND TEND TO TRAIN ALONG THE FRONT...SO THERE IS A POTENTIAL FOR AREAS TO SEE VERY HEAVY RAINFALL. WILL ADD CHC OF HEAVY DOWNPOURS TO THE PIEDMONT AREAS. BEST INSTABILITY IS IN THE NW NC FOOTHILLS AND MTNS BY LATE AFT. STORMS WILL LIKELY BE LESS NUMEROUS DOWN THAT WAY...BUT THE ONES THAT DEVELOP MAY BE SRONG ENOUGH FOR SOME HAIL OR STRONG WINDS. THINK THERE WILL PROBABLY BE AN AREA THAT COULD HAVE LIKELY POPS THIS AFT...JUST NOT CONFIDENT OF THE MVMNT OF THE FNT. LOOKING AT SATELLITE TRENDS...THINK THE FNT MAY BE SLOWER THAN MODEL PROGS. SO...I AM PLANNING TO CONINUE THE HIGH CHC POPS ARND 50 PCT. THICKNESSES INDICATE CURRENT MAX TEMP FCST IS RIGHT ON TRACK...WILL ADJUST HOURLY TEMPS AND SKY COVER. PREVIOUS DISCUSSION... (ISSUED 700 AM EDT THU MAY 12 2005) AVIATION... SOME LIGHT FOG ARND THIS MORNING SHUD BURN OFF QUICKLY WITH VFR CONDS PREVAILING THRU EARLY AFTERNOON. SCTD SHOWERS AND TSTMS WILL DEVELOP AHEAD OF COLD FRONT CRNTLY DROPPING SOUTH INTO NRN VA. BETTER CHCS AT BLF/ROA/DAN. ACTIVITY CONTS DROPPING SOUTH INTO THE CAROLINAS THIS EVENING WITH THE FRONT. WINDS BECOME NE THEN E BEHIND THE FRONT TNGT WITH LOWER CIGS AND VSBYS MOVING IN. MOSTLY LKG AT MVFR BY 12Z FRIDAY. PREVIOUS DISCUSSION... (ISSUED 315 AM EDT THU MAY 12 2005) SHORT TERM (TODAY THRU SAT)... STRONG COLD FRONT MOVING INTO WV AND KY THIS MORNING WILL PUSH THRU THE REGION LATER TODAY AND TONIGHT THEN STALL JUST SW OF THE FCST AREA FOR FRIDAY. CONVERGENCE ALONG AND AHEAD OF THE FRONT WILL MEET WARM UNSTABLE AIR OVER THE AREA THIS AFTN AND SHUD RESULT IN SCTD SHOWERS AND TSTMS IN MOST AREAS. WITH DEGREE OF INSTAB THIS AFTN SOME STORMS COULD BE APPROACHG SVR LIMITS. ANOTHER CONCERN IS WELL ABOVE NORMAL PCPBL WATER NUMBERS EXPECTED ESP OVER SE PTNS OF THE FA (APPRCHG 1.70 INCHES). TSTMS LIKELY TO PRODUCE VERY HEAVY RAINFALL RATES. TSTMS WILL LINGER INTO TNGT ALONG AND NEAR THE FRONT AS IT SAGS FURTHER SOUTH AND LEAVES MUCH OF THE FA WITH COOLER ENE FLOW. LOOK FOR PLENTY OF LOW CLOUDS...FOG AND DRZL OVER NE SECTIONS OF THE FA INTO FRIDAY NIGHT WHILE CHC OF CONVECTION LINGERS ALONG THE WESTERN EDGE. WARM FRONT LIFTS BACK TO THE NORTH SAT AS NEXT UPR TROF DIGS INTO THE GREAT LAKES RGN AND BRINGS PROGRESSIVE FRONT TOWARD THE AREA LATE SAT AND EARLY SUNDAY. SAT COULD BE A TRICKY FCST IF COOLER AIR GETS SOCKED IN ACROSS THE NE AND DOESNT ERODE QUICKLY ENUF. OTHERWISE TEMPS COULD REALLY WARM UP AHEAD OF COLD FRNT. CRNT FCST REFLECTS TOTAL EROSION OF COOL WEDGE. PREVIOUS DISCUSSION... (ISSUED 135 AM EDT THU MAY 12 2005) AVIATION...UPDATED. SATELLITE LOOP SHOWED HIGH CLOUDS...FROM THE CONVECTION ACROSS OHIO VALLEY...DROPPING SOUTH ACROSS OUR REGION THIS MORNING. A FEW SHOWERS AROUND KSHD NOTED ON KFCX 88D THIS MORNING WILL DROP SOUTHEAST NORTH OF KLYH. THIS ACTIVITY HAS BEEN WEAKENING AS IT RUNS INTO THE DRY AIR ACROSS THE REGION. MOST AIRPORTS HAVE VFR CONDITIONS THIS MORNING. POCKETS OF MVFR FOG COULD FORMED LATER THIS MORNING ACROSS WESTERN AIRPORTS LIKE KLWB. COLD FRONT WILL DROP SOUTH ACROSS OUR AREA TODAY. SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG THE BOUNDARY THIS AFTERNOON AND THIS EVENING. THE FRONT SHOULD PUSH SOUTH INTO NORTH CAROLINA THURSDAY NIGHT. VFR CONDITIONS WILL DETERIORATE TO AREAS OF MVFR WITH ISOLD IFR IN CONVECTION AND LOW CLOUDS. PREVIOUS DISCUSSION... (ISSUED 732 PM EDT WED MAY 11 2005) SHORT TERM (REST OF TONIGHT)... UPDATE WILL BE ISSUED LATER ON THIS EVENING TO REMOVE EVENING THUNDERSTORM WORDING. WILL PROBABLY LEAVE SLIGHT CHANCE OF SHOWERS AFTER MIDNIGHT SINCE CANT RULE OUT ROUGE SHOWER DEVELOPING ALONG FRONTAL BOUNDARY ACROSS CENTRAL OHIO...AND THEN MOVING IN FROM THE NORTH TOWARDS MORNING. WILL ALSO TAKE QUICK LOOK AT TEMP AND DEWPOINT TRENDS...AND ADJUST AS NECESSARY. AVIATION... RAIN CHANCES ARE QUICKLY DIMINISHING THIS EVENING...SO PRECIP WILL NOT BE MENTIONED IN ANY TAFS. AREARS OF MVFR FOG HAD FORMED EARLY THIS MORNING...AND EXPECT MORE OF THE SAME AGAIN OVERNIGHT TONIGHT ACROSS AREAS WEST OF THE BLUE RIDGE. MEANWHILE...TOMORROW WILL SEE A COLD FRONT MOVING INTO THE AREA. SHOWERS AND THUNDERSTORMS WILL BE DEVELOPING ACROSS THE REGION BY TOMORROW AFTERNOON. SINCE IT WILL BE AT THE VERY TAIL END OF THE FORECAST PERIOD...HAVE ELECTED TO LEAVE OUT FOR NOW. PREVIOUS DISCUSSION... (ISSUED 347 PM EDT WED MAY 11 2005) SHORT TERM (TONIGHT THROUGH THURSDAY)... DIURNAL CONVECTION WILL END THIS EVENING. BACKDOOR FRONT TO MOVE INTO THE REGION FROM NORTH TO SOUTH LATE TONIGHT THRU THE DAY THU. LONG TERM (THURSDAY NIGHT THROUGH WEDNESDAY)... THU NIGHT-FRIDAY...SFC BOUNDARY TO WORKS ITS WAY THRU THE AREA THU EVENING BUT WILL IT MAKE IT TO BLF AND MTN EMPIRE? CONVECTION ALONG THE BOUNDARY WILL GRADUALLY SHIFT TO THE SOUTH AND EAST OVERNIGHT. ONCE FRONT SINKS SOUTH OF THE AREA...ISENTROPIC LIFT AND EASTERLY UPSLOPE COMPONENT TO KEEP A CHC FOR LIGHT RA AND/OR AREAS OF DZ THRU AT LEAST FRIDAY MORNING...MAYBE LONGER FOR THE S SHENANDOAH VALLEY AND LYH VICINITY. WITH CAD EVENT...TEMPS TRICKY ENOUGH...BUT WITH BOUNDARY NOT MAKING IT COMPLETE THRU THE AREA MAKES IT EVEN MORE TOUGH. WARMEST AREA WILL BE TOWARDS THE MTN EMPIRE (M/U 70S) AND MAY BE WARMER THAN FORECASTED IF CLOUDS BREAK. OTHER AREA...ESPECIALLY EAST WILL HAVE MORE CLOUDS AND AN EASTERN FLOW TO BRING TEMPS 5-10F BELOW NORMAL. SAT...IF/WHEN WEDGE BREAKS...BOUNDARY WILL RETREAT AS A WARM FRONT PLACING AREA IN A WARM SECTOR. NO SIGNIFICANT LIFTING MECHANISM IN THE AREA SO ANY CONVECTION FIRING UP WILL PRIMARILY BE DUE TO DIFFERENTIAL HEATING. WITH BEST DYNAMICS IN THE OH VALLEY AND MID WEST...HAVE REDUCED POPS ESPECIALLY IN THE MORNING. SAT NIGHT...COLD FRONT STRETCHING FROM THE OH/TN VALLEY BACK INTO THE TX COAST WILL MOVE THRU THE AREA SUNDAY MORNING. THIS FRONT SHOULD BE ALONG THE EAST COAST BY SUNDAY EVENING. INSTABILITY AHEAD OF THE FRONT COULD BRING TSRA INTO THE AREA BUT MAJORITY OF THE ENERGY STAYS WELL TO THE NORTH IN THE GREAT LAKES/OHIO VALLEY REGION. TIMING OF THE FRONT ALSO HAVING AN AFFECT TO REDUCE CONVECTION POSSIBILITIES WITH FRONT SLICING THE AREA SUNDAY MORNING. MON-WED...ONCE FRONT PASSES...SFC HIGH PRESSURE MOVES INTO THE REGION. UPPER LEVEL TROUGHINESS OVER THE SFC HIGH WILL ALLOW FOR A FEW FAIR WEATHER CU TO FORM IN THE AFTN...BUT FORECAST LOOKS DRY FOR THE FIRST PART OF NEXT WEEK. && .RNK WATCHES/WARNINGS/ADVISORIES...
