NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Jul 8, 8:23 PM EST, 3 hours 37 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 923 PM EDT THU JUL 8 2010 .SYNOPSIS... LOW PRESSURE OFF THE CAROLINA COAST WILL SPREAD MOISTURE WESTWARD INTO THE AREA...AND THIS IS EXPECTED TO HELP GENERATE ISOLATED TO SCATTERED THUNDERSTORMS INTO THE OVERNIGHT. A WEAK COOL FRONT WILL MOVE SOUTHEAST ACROSS THE AREA SATURDAY...PROVIDING A BETTER CHANCE OF SHOWERS AND STORMS LATER FRIDAY INTO SATURDAY. WEAK HIGH PRESSURE WILL FOLLOW THE FRONT BRINGING DRIER AND SOMEWHAT COOLER WEATHER FOR SUNDAY INTO EARLY NEXT WEEK. && .NEAR TERM /THROUGH FRIDAY/... TYPICAL LATE EVENING CONVERGENCE ALONG THE BLUE RIDGE COMBO WITH OUTER RIM OF MOISTURE BAND FROM LOW OFF THE COAST HAS RESULTED IN A PERSISTENT BAND OF BROKEN TSRA DOWN THE RIDGELINE THIS EVENING. LATEST EVENING SOUNDINGS ALSO SHOW THAT THE CAP HAS ERODED WITH PWATS NEARING 1.3-1.5 SO OUTFLOW DRIVEN STORMS LIKELY WONT BE IN A HURRY TO FADE DESPITE LOSS OF HEATING. THIS ALSO SUPPORTED BY LINGERING HIGH INSTABILITY ALONG THE EASTERN SLOPES PER SPC MESO PAGE. LOCAL WRF ALSO SHOWS SOME OF THIS COVERAGE SPILLING BACK INTO THE LOWER ELEVATIONS SO UPDATED TO KEEP CHANCE POPS GOING INTO THE EARLY MORNING HOURS MAINLY ALONG/EAST OF THE BLUE RIDGE. HOWEVER IF COVERAGE DOES START TO DIMINISH WILL UPDATE AGAIN TO REMOVE OR LOWER POPS BACK TO JUST ISOLATED CHANCES BY MIDNIGHT. BASICALLY LEFT TEMPS STATUS QUO GIVEN SOME COOLING BY OUTFLOW/RAINFALL IN SPOTS...OTRW A VERY WARM/MUGGY OVERNIGHT WITH MOST SPOTS OUT EAST STAYING AT OR ABOVE 70 FOR LOWS. PREVIOUS DISCUSSION BELOW... STRONG HEATING COMBINED WITH A PLUME OF HIGH MOISTURE SHOULD RESULT IN ISOLATED TO SCT CONVECTION. AS EXPECTED FROM THIS MORNING MODIFIED RNK SOUNDING MLCAPE ARE AOA 2000 J/KG. NORTHEAST TO EAST FLOW IS INCREASING THIS AFTERNOON INTO TONIGHT AS THE UPPER LOW RETROGRADES WESTWARD TOWARDS THE OUT BANKS. THE WRFARW-RNK...NAM... SREF AND GFS SUPPORT THE MENTION OF ISOLATED CONVECTION. ANY THUNDERSTORM THAT DEVELOPS COULD CONTAIN HEAVY DOWNPOURS AND STRONG GUSTY WINDS. ADDED SOME PATCHY FOG TONIGHT ESPECIALLY IN THE WEST. OVERNIGHT LOWS WILL BE UNSEASONABLE MILD WITH READING CLOSE TO ADJMETBC FROM THE MID 60S IN THE WEST TO THE LOWER 70S IN THE SOUTHEAST. ON FRIDAY...THE UPPER LOW OFF THE COAST WILL SLOWLY MERGE WITH A COLD FRONT TO THE WEST THROUGH FRIDAY NIGHT. THIS WILL FORCE THE UPPER RIDGE TO THE SOUTHWEST. HIGH TEMPERATURES WILL BE A FEW DEGREES COOLER FRIDAY NEAR ADJMETBC BUT WITH DEWPOINTS IN THE MID TO UPPER 60S...IT WILL STILL BE MUGGY. PLACED THE HIGHEST POPS IN THE WEST FOR FRIDAY. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/... ONGOING FORECAST OF HIGHER POPS IN THE MTNS FRI NIGHT SEEM REASONABLE AS THE UPPER TROUGH MOVES INTO THE CENTRAL/SRN APPS WITH THE COLD FRONT SLOWLY TRACKING INTO THE LEE TROUGH BY 12Z SAT. DESPITE DEEP MOISTURE WITH PWATS ABOVE 2 INCHES...THE SYSTEM WEAKENS ENOUGH THRU THE PIEDMONT TO LOWER POPS TO CHANCE CAT. STILL POTENTIAL FOR HEAVY DOWNPOURS IN THIS ENVIRONMENT THOUGH WILL LEAVE OUT OF THE WEATHER GRIDS FOR NOW. THE FRONT WILL LINGER IN THE PIEDMONT SAT DURING THE MORNING B4 SECONDARY WAVE ALOFT AND THE SFC PUSHES ACROSS. DESPITE THIS...THE SVR THREAT WILL BE MINIMAL DUE TO MORE CLOUD COVER...BUT CANNOT RULE OUT STRONGER WINDS DOWN TOWARD THE SOUTHSIDE VA AREA SAT AFTN. BY SAT NIGHT...THE AIRMASS DRIES SOMEWHAT WITH TRANSITION TO CLEARING SKIES AND HIGH PRESSURE PUSHING INTO THE CENTRAL AND SRN APPALACHIANS WHILE FRONT SHIFTS TO THE COAST. SUNDAY SHOULD BE A LESS HUMID DAY IN THE MTNS WITH A WESTERLY TO NW FLOW AT THE SFC AND ALOFT. IT WILL STILL BE WARM BUT CLOSE TO NORMAL. THE DEWPOINTS MAY STAY UP ALONG THE PIEDMONT SINCE THE FRONT ACROSS THE COAST WILL BE HOLDING THE DRY POCKET BACK OVER THE MTNS. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... KEEPING THE FORECAST CLOSE TO HPC PREFERENCE OF ENSEMBLES BLENDED WITH 00Z ECMWF. STILL LOOKING AT EXTENDED PERIOD OF TYPICAL SUMMER HERE IN THE EAST WITH INCREASED HUMIDITY AS TROUGH REMAINS ACROSS THE MS VALLEY EAST TO THE OHIO VALLEY AND FLOW WILL BE MORE SW TO SOUTH. FRONTS WILL WEAKEN AS THEY MOVE TOWARD THE MTNS TUESDAY...BUT WITH INCREASED SFC DEWPOINTS AND CONVERGENCE SHOULD SEE A CHANCE OF POPS TUE-WED. HIGH TEMPS WILL BE AT OR JUST ABOVE NORMALS WITH THE HIGHER MOISTURE CONTENT IN THE AIR KEEPING OVERNIGHT LOWS ABOVE NORMAL...IN THE MID 60S TO LOWER 70S. ON THURSDAY...THERE IS A WEAK CONVERGENT AXIS LEFT OVER THE SE BUT WILL KEEP SLIGHT CHANCE POPS IN FOR NOW. && .AVIATION /01Z FRIDAY THROUGH TUESDAY/... WIDELY SCATTERED SHRA/TSRA CONTINUE TO DEVELOP AND PIVOT OFF TO THE SW THIS EVENING...MAINLY FROM THE BLUE RIDGE SE INTO THE PIEDMONT AROUND KDAN. EXPECT MAY SEE MORE TSRA DEVELOP AROUND KROA DESPITE LOSS OF HEATING GIVEN INSTABILITY SO INCLUDED A VICINITY/TEMPO MENTION OF MVFR CONDITIONS THERE THRU ABOUT MIDNIGHT. ALSO STORMS ENCROACHING ON KDAN WILL LIKELY MAKE FOR AN HOUR OR TWO OF MVFR/IFR WITH GUSTS TO 35 KTS POSSIBLE. EXPECT ALL OTHER SITES TO REMAIN VOID OF CONVECTION IN THE NEAR TERM SO WONT INCLUDE ATTM. OTRW WEAKENING HIGH PRESSURE AT THE SURFACE AND ALOFT OVER THE REGION WILL PROVIDE MAINLY VFR CONDITIONS LATER TONIGHT. INCREASING LOW LEVEL MOISTURE IN AN ONSHORE EASTERLY FLOW WILL CREATE POCKETS FOG/HAZE INTO EARLY FRIDAY...ESPCLY AFTER MIDNIGHT THRU DAYBREAK WHEN PERIODS OF MVFR LIKELY AT A FEW SITES. UPPER LOW ALONG THE COAST STARTS TO LIFT OUT FRIDAY AS A COLD FRONT SLOWLY APPROACHES FROM THE NW LATE IN THE DAY. LOOKS LIKE WILL STAY IN A VFR BUT HAZY REGIME BETWEEN THESE TWO SYSTEMS UNTIL LATE FRIDAY WHEN SOME PRE- FRONTAL STORMS LIKELY MOVE INTO THE FAR WESTERN AREAS. CONFIDENCE HIGH ENOUGH THAT HAVE INCLUDED A CB/VCTS MENTION ACROSS THE SE WVA LOCATIONS TOWARD THE END OF THE TAF PERIOD FRIDAY...AND CB AT KROA...BUT LITTLE CONVECTIVE MENTION OUT EAST. MORE WIDESPREAD SHOWERS AND THUNDERSTORMS WITH MVFR/POSSIBLE IFR ARE EXPECTED ACROSS THE ENTIRE AREA FRIDAY NIGHT INTO SATURDAY AS A WEAK COLD FRONT SLIDES THROUGH THE REGION. DRIER WEATHER UNDER VFR CONDITIONS WILL RETURN AGAIN ON SUNDAY AND LINGER INTO EARLY NEXT WEEK. && .CLIMATE...
