NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Aug 10, 2:54 PM EST, 11 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 354 PM EDT MON AUG 10 2009 .SYNOPSIS... A FRONTAL BOUNDARY WILL APPROACH THE REGION BY LATE TUESDAY AND STALL OVER THE AREA WEDNESDAY AND THROUGH THE REMAINDER OF THE WEEK. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... WHILE CONVECTION CROSSING THE NORTHERN PORTION OF THE FCST AREA THIS AFTERNOON SHOULD WEAKEN BY EVENING AS IT CROSSES THE BLUE RDG UNDER WRLY FLOW...KEPT A LINGERING LOW CHC POP ACROSS THE FOOTHILLS OF NW NC DUE TO LEE TROUGH AND SOME OF THE MODELS...NAM ESPECIALLY....CONTINUING ACTIVITY THROUGH THE EVENING HOURS. OTHERWISE SCATTTERED CONVECTION CLOSER TO THE FRONT IN THE OHIO VALLEY COULD ALSO LINGER MUCH OF THE OVERNIGHT...SO A LOW CHC POP FAR WEST AS WELL. WITH DEBRIS CLOUDS COVER...ESPECIALLY IN THE WEST...TEMPS SHOULD ONCE AGAIN BE MILD AS THEY WERE LAST NIGHT...SO WENT A LITTLE HIGHER THAN GUIDANCE IN MINS. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/... FRONTAL BOUNDARY APPROACHES BY LATE TUES...AND WILL BE RIGHT OVER THE FCST AREA BY WED AS WEAK UPPER TROUGH DIGS JUST WEST OF APPALACHIANS. TRICKY FCST IN TERMS OF THE DETAILS AND TIMING CONVECTION...WITH POSSIBILITY OF WEAKENING OVERNIGHT ACTIVITY IMPACTING THE WEST EARLY IN THE DAY...BUT AT THE SAME TIME ANY SHWRS OR CERTAINLY CLOUD COVER COULD PUT A DAMPER ON NEW CONVECTION LATER IN THE DAY. IF LITTLE MATERIALIZES OVERNIGHT TONIGHT...WILL SEE BETTER CHANCE ALL LOCATIONS IN THE WEST BY MIDDAY. WRLY FLOW SHOULD KEEP ACTIVITY AT A MINIMUM MOST OF THE DAY TUESDAY...BUT SFC-BASED CAPE IN THE 1000-1500 J/KG RANGE COULD STILL BE ENOUGH TO GET RELATIVELY WEAK AND LIKELY ISOLD CONVECTION GOING BY LATE AFT. A LITTLE MORE SUN EXPECTED IN THE EAST...SO SHOULD BE ANOTHER HOT ONE WITH TEMPS IN MID 90S AND HEAT INDEX VALUES UPPER 90S TO NEAR 100...DOWN JUST A CUPL DEG FROM TODAY. BY TUES NIGHT FRONTAL BOUNDARY SHOULD BE MOVING INTO WRN PORTION OF AREA AND GOOD CHC OF ONGOING CONVECTION MOVING IN FROM WEST OVERNIGHT. IF ORGANIZING ENOUGH...COLD POOLS COULD PUSH BOUNDARY TO THE SOUTHEAST DURING THE DAY WED...OTHERWISE WE MAY SEE ACTIVITY IN THE WEST DURING THE MORNING...JUMPING ACROSS INTO THE LEE TROUGH IN THE EAST BY AFTERNOON WITH A RELATIVE MINIMUM IN ACTIVITY IN THE MIDDLE...EXPECIALLY FROM ROANOKE UP THE I-81 CORRIDOR. WENT MAINLY WITH HIGH CHC POPS...EMPHASIS ON WEST EARLY AND EAST LATER...BUT WITH BAND OF LOW LIKELY POPS IN THE FAR SOUTHEAST WHICH WILL BE THE MOST LIKELY LOCATION FOR COMBINATION OF CONVERGENCE AND MAX HEATING. THURSDAY...BIG QSTNS AS TO HOW FAR OF A SOUTHEAST PUSH THE BOUNDARY GETS...WITH MOST GUIDANCE SUGGESTING IT GETS INTO CNTRL CAROLINAS...STILL CLOSE ENOUGH TO GIVE THREAT AGAIN ACROSS THE SOUTHERN PORTION OF CWA. 12Z NAM NOW HAS STRONGER WAVE LIFTING NORTH DURING THE DAY...SPREADING PRECIP NORTH AND WESTWARD AGAIN...BUT PROBABLY OVER SHALLOW FAIRLY STABLE AIRMASS...BUT BELIEVE THERE WILL BE SOME ELEVATED CONVECTION WITH THIS. SO WENT WITH CHC POPS EVERYWHERE...BUT HIGHER ACROSS THE SOUTH. COOLER HIGHS DUE TO PLENTY OF CLOUD COVER AND MAY NEED TO GO EVEN COOLER IF LOOKS LIKE WELL HAVE STEADIER RAIN OVER THE EASTERLY FLOW AT LOW LEVELS. TENDED TO GO WITH MILDER MET GUIDANCE FOR MINS AND COOLER GUIDACE FOR MAXS DURING THE PERIOD...EXCEPT FOR TUES GOING WITH WARMER MAV FOR HIGHS. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... REGARDLESS OF WHETHER THE FRONTAL BOUNDARY MANAGES TO MAKE IT SOUTHEAST OF THE AREA BY EARLY THURSDAY OR NOT...THERE APPEARS TO BE MODEL AGREEMENT THAT THE BOUNDARY WILL EITHER WASH OUT OR SLIDE BACK TOWARD THE NORTH BY THURSDAY EVENING. WITH WEAK UPPER TROUGH REMAINING JUST TO THE WEST OF THE CWA WHICH IS CONSENSUS THINKING FROM 00Z AND 06 OPERATIONAL AND ENSEMBLE GUIDANCE...AND NOW SUPPORTED BY THE 12Z GFS...THIS SHOULD KEEP A MOIST SOUTHERLY FLOW THROUGH THE WEEKEND WITH 850MB SOUTHERLY FLOW RETURNING BY FRIDAY. SFC FLOW MORE SOUTHEASTERLY THROUGH EARLY PART OF WKND...SO POSSIBLE ENHANCEMENT OF CONVECTION AND PRECIP ALONG THE BLUE RDG...THEN SHIFTING MORE SW BY LATE IN THE WKND AS UPPER TROUGH FADES AND RIDGE BUILDS A LITTLE. PLENTY OF CONVECTIVELY INDUCED WAVES HEADING IN FROM WEST DURING OVERNIGHT HOURS DURING THIS PERIOD SO COULD HAVE A NUMBER OF NIGHTS WITH CONVECTION CONTINUING...SO GENERALLY KEPT CHC POPS INTO THE NIGHT PERIODS. BY MONDAY...WARMER TEMPS ALOFT AND PERHAPS MORE WESTERLY FLOW...ALBEIT WEAK...COULD HELP SUPPRESS CONVECTIVE CHANCES...HOWEVER ENOUGH UNCERTAINTY THIS FAR OUT...AND CONSIDERING CLIMATOLOGY OF THE SEASON...CERTAINLY NOT GOING TO DROP POPS ALL THE WAY...BUT LOWERING TO SLIGHT CHC TO SUGGEST POSSIBILITY OF A DRIER DAY. CONSIDERING THAT THIS WILL BE AN EXTENDED RATHER WET PERIOD...WITH MANY AREAS GETTING A CHANCE TO PICK UP SOME HEAVY RAINFALL BY THE END OF THE WEEKEND...A DRY DAY MAY BE A WELCOME RELIEF...BUT NOT ENTIRELY SURE ITS GOING TO HAPPEN. ALSO SEEING SOME SIGNS OF TROPICAL WAVES MAKING IT INTO THE GULF BY EARLY NEXT WEEK..SO WILL HAVE TO KEEP OUR EYE ON THIS POTENTIAL ADDITIONAL MSTR SOURCE. WENT WITH HPC GUIDANCE FOR TEMPERATURES DURING THE PERIOD BUT WITH A SLIGHT UPWARD BOOST ON MONDAY. && .AVIATION /20Z MONDAY THROUGH SATURDAY/... HEATING TODAY ALONG WITH DEWPOINTS IN THE LOWER 70S HAS ALLOWED FOR A MODERATELY UNSTABLE AIRMASS...THOUGH TEMPS ALOFT ARE WARM ENOUGH THAT MID LEVEL LAPSE RATES ARE STILL FAIRLY WEAK. RADAR/SATELLITE SHOWS SCAT TSTMS DEVELOPING OVER THE WESTERN SLOPES OF THE MTNS. WESTERLY FLOW SHOULD TEND TO KEEP TSTMS FROM MOVING TOO FAR EAST OF THE MTNS. HAVE INCLUDED VCNTY TSTMS IN THE BLF AND LWB TAFS...WITH TEMPO GROUPS WHEN THEY HAVE THE BEST CHC TO SEE SHOWERS AND MVFR CONDS. FOR ROA...WITH TSTMS PASSING THRU RIGHT NOW...I HAVE A 1 HOUR TEMPO GROUP...WITH 2 HOURS OF VCNTY TSTMS. TSTM ACTIVITY SHOULD BE MAINLY DIURNAL TODAY...SO CHCS ARE TOO LOW TO MENTION IN TAFS AFTER MID EVENING. THINK THAT DEBRIS MID AND HIGH CLOUDS WILL KEEP MUCH FOG FROM DEVELOPING OVERNIGHT...BUT HAVE INCLUDED SOME MVFR FOG AND CIGS AT BLF/LWB...AND MVFR FOG AT DAN. THERE WILL BE A GOOD CHC FOR TSTMS AGAIN ON TUESDAY...BUT SHOULD BE MAINLY AFTER 18Z. THE APPROACH OF A COOL FRONT AND ASSOCIATED SHOWERS/THUNDERSTORMS IN THE TUESDAY AFTERNOON - THURSDAY TIME FRAME WILL RESULT IN A MORE WIDESPREAD THREAT OF MVFR/POSSIBLE IFR RESTRICTIONS WITH SHOWERS AND THUNDERSTORMS. MORE TYPICAL AIRMASS TYPE AFT/EVE THUNDERSTORMS ARE EXPECTED FRIDAY AND SATURDAY...WITH THE BEST COVERAGE IN THE MTNS. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...NONE. NC...NONE.
