NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Jul 23, 2:27 PM EST, 35 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 327 PM EDT THU JUL 23 2009 .SYNOPSIS... DRIER AIR WILL EASE IN FROM THE WEST TONIGHT...WITH ONLY ISOLATED SHOWERS POSSIBLE ALONG THE WESTERN SLOPES OF THE ALLEGHANY MOUNTAINS ON FRIDAY. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO RETURN TO THE WEST AS EARLY AS SATURDAY NIGHT AHEAD OF THE NEXT COLD FRONT. && .NEAR TERM /THROUGH FRIDAY/... SCT SHOWERS AND THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON ALONG AND EAST OF THE BLUE RIDGE AHEAD OF THE COLD FRONT IN THE UNSTABLE AIR. THE COLD FRONT WILL SWEEP EAST TONIGHT ACROSS CWA. SHOWERS AND THUNDERSTORMS WILL BECOME MORE NUMEROUS THIS EVENING INTO TONIGHT. SOME OF THE STORMS COULD BE STRONG THIS AFTERNOON WITH CAPES AROUND 1500 TO 2000 J/KG AND MID LEVEL SOUTHWEST WINDS AROUND 30 KNOTS. WITH PWATS ABOUT 1.2 TO 1.5 INCHES EAST OF BLUE RIDGE...HEAVY RAINS MAY BE POSSIBLE WITH THUNDERSTORMS AND ECHO TRAINING. INCREASED POPS USING A WRFARW-RNK/SREF BLEND THEN TRENDED POPS TOWARDS NAM/GFS SOLUTION. KEPT TIMING OF FROPA AROUND 06Z WITH THE BEST CHC OF THUNDERSTORMS IN THE EAST EARLY...AND LEANED TOWARDS MET GUIDANCE FOR LOWS TONIGHT. KEPT FORECAST DRIER FOR FRIDAY WITH THE EXCEPTION OF SOME SMALL POPS IN THE WESTERN MTNS AS BOTH NAM AND GFS INDICATE AN IMPULSE ROTATING AROUND UPPER TROF. BUFKIT SOUNDINGS INDICATE DEEP WESTERLY FLOW...WHICH SHOULD BRING WARMER TEMPERATURES. ELECTED TO GO WITH HIGHS CLOSER TO WARMER MOS GUIDANCE FROM UPPER 70S IN THE NORTHWEST TO NEAR 90 IN THE SOUTHEAST. && .SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/... DRIER DEW PTS SHOULD ALLOW FOR COOLER OVERNIGHT LOWS...AND DESPITE SOME WEAK CONVERGENCE IN NW NC MTNS SHOULD BE DRY ENOUGH AIR ALOFT WITH SOME SUBSIDENCE TO KEEP SHWRS THAT NAM IS HINTING AT FRIDAY NIGHT AT BAY. GENERALLY DRY FOR SATURDAY...BUT WITH SW FLOW RETURNING LATE DECIDED TO INTRODUCE SLGHT CHC POP TO FAR WRN MTNS WITH DEEPER INSTABILITY DEVELOPING. MAY END UP HAVING TO EXPAND AT THE SLGT CHC TO MORE OF THE MTNS EVENTUALLY IF MODELS SHOW A CONTINUED TREND IN RETURN OF MSTR. BETTER CHANCES IN THE WEST OVERNIGHT SAT NIGHT AS CONVECTION AHEAD OF FRONTAL SYSTEM IN OHIO VALLEY APPROACHES. CANADIAN REALLY HINTING AT SOME KIND OF QUASI-LINEAR MCS WHICH COULD RACE WELL AHEAD...THIS ANOTHER REASON FOR SLIGHT CHC POPS BY LATE SATURDAY AND STEADILY INCREASING DURING THE OVERNITE HOURS. PRETTY GOOD CHC OF THUNDER WITH ANY SHWRS MVG IN REGARDLESS OF TIME OF NIGHT WITH THIS. WITH WESTERL FLOW DEVELOPING...EVEN THOUGH FROTNAL BOUNDARY HANGS BACK WELL TO WEST...ANY CONVECTION WILL HAVE DIFFICULT TIME GETTING TOO FAR EAST. LEANED TOWARD SOMEWHAT COOLER MET GUIDANCE FOR HIGHS SATURDAY BUT THIS STILL PUTS THE FAR SOUTHEAST AROUND 90 DEG OR SO WITH PLENTY OF SUNSHINE AND SW FLOW. && .LONG TERM /SUNDAY THROUGH THURSDAY/... LITTLE CHANGE IN MEDIUM RANGE MODEL GUIDANCE FROM 24 HRS AGO...AND THUS LITTLE CHANGE TO HPC GUIDANCE IS WELL. WENT LARGELY WITH ECMWF IDEA OF A LITTLE SLOWER PROGRESSION EARLY IN THE WEEK OF THE FRONTAL BOUNDARY. THIS WOULD MEAN FRONT REMAINS TO WEST ON SUNDAY WITH BEST PRECIP CHANCES IN WEST...PLAYED IT CHC EVERYWHERE FOR NOW...BUT MAY END UP BEING A TIHGT GRADIENT IN POPS FROM WEST TO EAST WITH WESTERLY FLOW ALOFT EVEN THOUGH SFC FRONT WELL TO THE WEST. SLOWER FRONTAL PROGRESSION WOULD ALSO MEAN KEEPING CHC OF SHWRS/TSTMS IN FOR ALL AREAS EVEN ON MONDAY INSTEAD OF JUST THE EAST. BY MONDAY NIGHT AND TUESDAY POSSIBLY A QUICK BREAK IN ACTIVITY...AT LEAST IN THE WEST...BUT STILL TOUGH TO CONFIDENTLY BELIEVE THE BOUNDARY WILL BE FAR ENOUGH TO EAST AND NOTICABLY DRIER AIR BEHIND IT TO COMPLETELY REMOVE PRECIP CHANCES. MODELS AGREE THAT NEXT WEAK FRONTAL BOUNDARY WILL BEGIN TO APPROACH BY WED WITH INCREASING MOIST SW FLOW AHEAD OF IT. WITH MEAN TROUGH POSITION RETROGRADING SOMEWHAT TO THE CENTRAL PART OF U.S. BY MID WEEK...APPEARS THIS FRONTAL BOUNDARY WILL STALL OUT TO THE WEST OF THE APPALACHIAN REGION...AND THICKNESSES WILL WARM SLIGHTLY AS WELL AS WEAK RIDGING OCCURS OVER THE MID ATLANTIC. THIS WILL LEAVE CHANCES FOR SCT SHWRS/TSTMS IN THE PICTURE THROUGH AT LEAST THURSDAY...BUT WITH BEST CHANCES OVER THE MTNS AS SW FLOW AND FRONTAL BOUNDARY LIKELY REMAIN JUST TO THE WEST. PROBABLY PLENTY OF CLOUD COVER ALONG WITH SHWR ACTIVITY...SO MAX TEMPS WILL BE MODERATED SOMEWHAT BY THAT...BUT CERTAINLY VERY MILD OVERNIGHTS...WITH AROUND 70 LIKELY IN THE PIEDMONT. WENT VERY CLOSE TO HPC GUIDANCE ON TEMPS AND DEW PTS. BOTTOM LINE...TYPICAL MID SUMMER PATTERN WITH DAILY CHANCES FOR MAINLY AFT/EVE SCATTERED CONVECTION...WITH SLIGHTLY BETTER CHANCES SUNDAY NIGHT AND MAYBE AGAIN BY WED NIGHT FOR S/WV ENERGY TO HELP SOME ACTIVITY LAST INTO THE OVERNIGHT HOURS. && .AVIATION /19Z THURSDAY THROUGH TUESDAY/... VFR CONDITIONS WILL PREVAIL WITH SCT MVFR CONDITIONS IN CLOUDS AND CONVECTION THIS AFTERNOON INTO TONIGHT. A COLD FRONT WILL MOVE EAST THROUGH THE AREA...CREATING SHOWERS AND THUNDERSTORMS. THE BEST CHANCE OF A THUNDERSTORM IS EAST OF THE BLUE RIDGE AT KDAN. THE FRONTAL BOUNDARY SHOULD CLEAR MOST OF CWA BY 06Z FRIDAY. DRIER WEATHER WILL FOLLOW THE FRONTAL PASSAGE TONIGHT INTO THE EARLY PART OF THE WEEKEND. THIS SHOULD ALLOW VFR CONDITIONS TO PREVAIL INTO THE WEEKEND BEFORE THE NEXT COLD FRONT ARRIVES LATER SUNDAY. THIS FRONT MAY BRING ANOTHER ROUND OF MVFR IN CONVECTION SUNDAY INTO SUNDAY NIGHT...AND PERHAPS ACROSS THE EAST ON MONDAY. OTRW TYPICAL MORNING FOG IS POSSIBLE ACROSS THE MOUNTAIN VALLEYS WITH IFR FOG IN THE GREENBRIER VALLEY (LWB). && .RNK WATCHES/WARNINGS/ADVISORIES... VA...NONE. NC...NONE.
