NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Jul 22, 8:32 PM EST, 53 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 932 PM EDT WED JUL 22 2009 .SYNOPSIS... A COOL FRONT WILL MOVE OUT OF THE OHIO VALLEY AND THROUGH THE APPALACHIANS DURING THE DAY ON THURSDAY...BRINGING A GOOD CHANCE OF SHOWERS AS WELL AS ISOLATED THUNDERSTORMS BEGINNING TONIGHT AND THROUGH THE DAY ON THURSDAY. DRIER AIR WILL FILTER IN BEHIND THE FRONT BY THGURSDAY NIGHT...WITH HIGH PRESSURE INFLUENCING THE REGION THROUGH THE EARLY HALF OF THE WEEKEND. && .NEAR TERM /THROUGH THURSDAY/... WIDELY SCATTERED BANDS OF DEEPER CONVECTION CONTINUE ALONG THE LEADING EDGE OF THE PREFRONTAL TROF THIS EVENING AND EXPECT SOME OF THIS WILL LINGER OVERNIGHT PER INSTAB/PWATS. AGAIN THINK BEST COVERAGE WILL BE OVER THE NW LATER...CLOSER TO THE PASSING VORT AND ACROSS THE SOUTH WHERE FEED OF RH ALONG A WEAK CONVERGENCE AXIS LOOKS TO PERSIST. THIS SUPPORTED BY MOST SHORT TERM GUIDANCE SO EXTENDED CHANCE POPS A BIT FARTHER EAST OVERNIGHT AND BOOSTED COVERAGE OF LOW LIKELYS/HIGH CHANCE OVER THE WEST. LOBE OF DYNAMICS MAY ALSO KEEP A STRONGER STORM OR TWO AROUND DURING THE NEXT FEW HOURS...AND AGAIN LATE TONIGHT AS THE ACTUAL SURFACE FRONT APPROACHES. OTRW JUST SOME SMALL ADJUSTS TO INCREASE CLOUDS A LITTLE MORE OVERNIGHT AND TO RAISE TEMPS IN SPOTS GIVEN RATHER SOUPY DEWPOINTS AND CLOUD COVER. PREVIOUS DISCUSSION BELOW... WENT WITH LOW LIKELY POPS IN FAR WEST FOR TONIGHT....CHC ELSWHERE...BUT BETTER CHANCE THAN USUAL OF OVERNIGHT SHWRS AND ISOLD THUNDER GIVEN UPPER ENERGY AND INCREASING SRLY 850 JET. HARD TO TIME BEST CHANCES OF PRECIP THROUGHOUT THE DAY THURSDAY..BUT GENERALLY SHOULD BE IN THE WEST DURING THE MORNING...AND THE EAST DURING THE AFTERNOON WITH DIFFUSE FRONTAL BOUNDARY MOVING THROUGH. HOWEVER WRLY FLOW IN THE WEST BY AFTERNOON AND STILL PLENTY OF LOW LEVEL MSTR COULD KEEP SHWRS GOING FAR WEST. ALSO INCREASING TROPICAL MSTR AND ACTIVITY NEAR COASTAL FRONT TO THE EAST COULD BEGIN TO ROB MSTR FROM THE PIEDMONT AS BOUNDARY MOVES EAST...SO MAY BE A TENDECNY FOR ACTIVITY TO DISSIPATE AS IT GETS INTO THE PIEDMONT. MUCH ALSO DEPENDS ON ANY INSOLATION...WHICH APPEARS TO BE LIMITED. BLV ANY SEVERE THREAT IS VERY MINIMAL MAINLY DUE TO LACK OF HEATING THURSDAY...BUT SHEAR OVERNIGT AND EARLY TOMORROW WILL BE MARGINAL...SO WILL NEED TO KEEP ON EYE ON ANY DEEPER CONVECTION THAT CAN FORM...ESPECIALLY MIDDAY. TEMP WISE..LEANED TOWARD WARMER MET GUIDANCE FOR OVERNIGHT MINS GIVEN CLOUDS COVER...PRECIP...AND WEAK WARM ADVECTION. FOR HIGHS THURSDAY... STARTED WITH A BIAS-CORRECTED SREF SET OF TEMP GRIDS WHICH HAVE BEEN DOING WELL LATELY...BUT WARMED MORE TOWARD MET/MAV NUMBERS IN FAR EAST YET STILL ON COOL SIDE. && .SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/... LOW PRESSURE OVER THE GREAT LAKES WILL MARCH NORTHEAST THURSDAY AND PUSH A COLD FRONT ACROSS OUR REGION. THE COMBINATION OF A TROPICAL LOW OFF THE NORTH CAROLINA COAST AND THE UPPER TROUGH AMPLIFYING MAY SLOW OR STAFF THE FRONT DOWN...AS IT MOVES INTO CENTRAL VA THURSDAY EVENING. THERE STILL REMAIN A LARGE VARIABILITY IN THE EVOLUTION AND EVENTUAL TRACK OF SFC LOW ALONG THE COAST. IN ANYCASE...WITH THE BEST LIFT ASSOCIATED WITH UPPER/SFC LOW IN THE GREAT LAKES PULLING NORTH...BELIEVE THAT A BKN LINE OF SHOWERS/EMBEDDED TSRA SWING ACROSS CWA DURING THURSDAY EVENING INTO THURSDAY NIGHT. EXPECTING TO SEE A DIMINISHING TREND IN POPS THURSDAY NIGHT INTO FRIDAY...AS THE TROPICAL LOW AND SHORTWAVE MOVE TO THE NORTHEAST. 8H WINDS WILL BECOME NORTHWEST...AS RIDGE PUSHES NORTHEAST INTO THE TN VALLEY. CUT POPS IN THE EAST FRIDAY AS MODELS HAVE BACKED OFF LINGERING AREA OF TROFINESS. KEPT LIGHT POPS IN THE WEST WITH THE NW FLOW OVER THE SE WV MTNS...AS WEAK IMPULSES ROTATE AROUND THE UPPER TROUGH THAT HAS BEEN THE SEMI-PERMANENT PLAYER THIS SUMMER. OVERALL...FRIDAY SHOULD BE A DRIER AND WARMER DAY COMPARED TO THURSDAY. KEPT IT MAINLY DRY FRIDAY NIGHT AS WELL. THE NEXT FRONT LOOKS TO BE ARRIVING AT A LATER TIME FRAME THAN PREVIOUS FORECASTS SUGGEST. PLAYED NIGHTTIME LOWS FROM THE UPPER 50S IN THE WEST TO THE MID 60S IN THE EAST. WARMED HIGH TEMPERATURES ON FRIDAY INTO THE MID 70S IN THE NORTHWEST TO AROUND 90 IN THE SOUTHEAST. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... LEANED EXTENDED PERIOD TOWARDS HPC GUIDANCE WHICH FAVORED 00Z ECMWF WITH DASH OF THE 00Z/22 EC ENSEMBLE MEAN THROWN IN FOR GOOD MEASURE TO SMOOTH OUT SOME OF THE UNCERTAINTIES IN SYNOPTIC DETAILS. A COLD FRONT WILL APPROACH THE REGION SUNDAY AND SUNDAY NIGHT. WAVES OF LOW PRESSURE MAY DEVELOP ALONG THE FRONTAL BOUNDARY MONDAY AND SLOWS DOWN ITS EASTWARD MOVEMENT. UNSETTLED WEATHER WILL CONTINUE TUESDAY INTO WEDNESDAY. TEMPERATURES ARE EXPECTED TO MODERATE BACK TOWARDS NORMAL THROUGH THE WEEKEND AND COOL EARLY NEXT WEEK...THEN WARM UP BY MIDWEEK. && .AVIATION /01Z THURSDAY THROUGH MONDAY/... VFR CONDITIONS SHOULD PREVAIL THROUGH THIS EVENING WITH ISOLD SHRA/TSRA...BUT COVERAGE ONLY ENOUGH TO MENTION AS VICINITY OR IN A BRIEF PREVAILING GROUP MAINLY KLWB EARLY ON. PRE-FRONTAL BAND OF SHRA WILL ATTEMPT TO WORK IN FROM THE WEST OVERNIGHT...BUT EXPECT GIVEN LOSS OF HEATING THAT THE MAJORITY OF THE HEAVIER SHRA WILL REMAIN TO THE WEST UNTIL VERY LATE WHEN COVERAGE COULD REDEVELOP CLOSER TO THE BLUE RIDGE. LOWERING CIGS IN ADVANCE OF THIS PRECIP WILL LIKELY CAUSE PERIODS OF MVFR CONDITIONS...AND EVEN IFR OVERNIGHT IN PATCHY FOG AND PERHAPS IN A HEAVIER SHRA ACROSS SE WVA LATE. COULD ALSO SEE SOME IFR CIGS IN LYH BEFORE DAWN...PENDING CLOUDS/FOG BUT MORE SO AT KLWB WHERE LIFR POSSIBLE IN FOG GIVEN EARLIER RAINFALL. OFF AND ON PRECIP CHANCES LINGER THROUGH THE DAY THURSDAY...PROBABLY INCREASING AGAIN AT SOME POINT AS FRONT MOVES THROUGH MIDDAY ACROSS THE WEST AND OVER THE EAST IN THE AFTERNOON PENDING HOW MUCH HEATING TAKES SHAPE. THUS WILL COVER WITH CB MENTION OVER THE EAST...ESPCLY LATE IN THE TAF PERIOD AND KEEP A MORE SHRA VICINITY MENTION OVER THE WEST BEHIND THE FRONT IN THE AFTERNOON. DRIER WEATHER WILL FOLLOW THE FRONTAL PASSAGE THURSDAY NIGHT 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.
