NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Jun 4, 12:26 PM EST, 44 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 126 PM EDT FRI JUN 4 2010 .SYNOPSIS... A STATIONARY FRONT EXTENDS FROM THE MASON-DIXON WESTWARD INTO THE OHIO VALLEY...WITH A LEE TROUGH EAST OF THE APPALACHIANS. THE FRONT WILL DISSIPATE TODAY WITH NO SIGNIFICANT WEATHER FEATURES NOTED ASIDE FROM THE LEE TROF. A FAIRLY STRONG COLD FRONT WILL MOVE FROM THE UPPER MID WEST INTO THE OHIO VALLEY ON SATURDAY. THIS FRONT WILL MOVE SOUTHEAST ACROSS THE MID ATLANTIC REGION SUNDAY...SWEEPING WELL SOUTH OF THE AREA MONDAY. && .NEAR TERM /THROUGH TONIGHT/... RADAR RETURNS ACROSS THE AREA CLEAR THIS MORNING WITH A MUGGY EARLY SUMMER AIR MASS OVER THE ENTIRE AREA...DEWPOINTS IN THE MID-60S TO LOW 70S. MADE NO SIGNIFICANT CHANGES IN MORNING UPDATE AS HRRR AND WRF-RNK STILL SHOWING CONVECTIVE INITIATION ALONG THE SOUTHWESTERN BLUE RIDGE IN THE 18-20Z TIME FRAME FROM DIFFERENTIAL HEATING AND LEE TROUGHING WITH SCATTERED TO ISOLATED STORMS DRIFTING EAST THROUGH THE LATE AFTERNOON AND EVENING. THE FORECAST CLOUD LAYER MEAN WIND IS 250 DEGREES AT ABOUT 17 KTS. WITH WEAK WINDS ALOFT...NOT ANTICIPATING MUCH IN THE WAY OF ORGANIZATION. SEVERE THREAT WILL BE LIMITED TO A FEW PULSE STORMS WHICH MAY PRODUCE A STRONG DOWNBURST DUE TO THE HIGH DCAPE. TEMPS THIS AFTERNOON WILL BE SIMILARY TO THURSDAY WITH READINGS IN THE 80S...CLOSE TO 90 IN THE FOOTHILLS AND PIEDMONT. ANY SHOWER ACTIVITY THIS EVENING SHOULD DISSIPATE WITH THE LOSS OF INSOLATION...LEAVING US WITH ANOTHER MUGGY NIGHT...DEWPOINTS IN THE 60S KEEPING TEMPERATURES ELEVATED. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... WESTERLIES WILL BEGIN TO INCREASE AGAIN ON SATURDAY AS A COLD FRONT MOVES INTO THE OHIO VALLEY. A HIT OR MISS THUNDERSTORM IS POSSIBLE DURING THE AFTERNOON SATURDAY...BUT THINK MORE MISSES THAN HITS DUE TO A STRONGER DOWNSLOPE WESTERLY WIND COMPONENT. A STRONGER WEST WIND SUGGESTS TEMPERATURES MAY BE A DEGREE OR TWO WARMER...AND COMBINED WITH DEWPOINTS IN THE 60S WILL MAKE IT FEEL RATHER SULTRY. SUNDAY WILL BE A TRANSITION DAY WITH A THREAT OF ORGANIZED THUNDERSTORMS ALONG A COLD FRONT THAT WILL MOVE ACROSS THE AREA FROM THE NORTHWEST TO SOUTHEAST. MODELS BRING THE FRONT INTO THE NORTHWEST CWA SUNDAY MORNING...THEN SWEEP IT SOUTH AND EAST ACROSS THE FORECAST AREA DURING THE AFTERNOON...BRINGING A CHANGE IN AIRMASS SUNDAY NIGHT. ORGANIZED THUNDERSTORMS SUGGESTS POTENTIAL FOR SEVERE WEATHER. HOWEVER...TIMING OF THE FRONT IS KEY TO WHERE THE RISK WILL BE. IF THE FRONT MOVES INTO THE MOUNTAINS EARLY ENOUGH SUNDAY MORNING...THEN THIS MAY LIMIT THE THREAT OF SEVERE WEATHER TO JUST THE EASTERN CWA. TEMPERATURES SUNDAY WILL ALSO BE DEPENDENT ON FRONTAL TIMING AND ASSOCIATED CLOUD COVER. THINK TEMPS WILL STILL CLIMB INTO THE 80S...BUT MAY HAVE DIFFICULTY REACHING 90 PER THE EARLY FRONTAL TIMING. AT THE VERY LEAST IT WILL REMAIN HUMID WITH DEWPOINTS SPIKING CLOSE TO 70 PRIOR TO THE FRONTAL PASSAGE...WITH A REFRESHING DROP INTO THE 50S AFTER THE FRONTAL PASSAGE SUNDAY NIGHT. && .LONG TERM /MONDAY THROUGH THURSDAY/... MODELS STILL IN GENERAL AGREEMENT THAT ZONAL UPPER FLOW WILL TRANSITION TO A MORE AMPLIFIED PATTERN...WITH A 5H TROF ACROSS THE EASTERN CONUS EARLY NEXT WEEK. MAIN QUESTION IS STRENGTH OF EASTERN TROF...WITH MODELS INDICATING A RELATIVELY DRY NORTHWEST FLOW ON MONDAY...THEN DIVERGE ON VARIED DEGREE OF MOISTURE RETURN TUESDAY AND WEDNESDAY DEPENDING ON HOW AMPLIFIED THE TROF IS OR ISNT BY THE MIDDLE OF THE WEEK. FOR NOW WILL START OFF THE WEEK DRY... THEN SLOWLY TRANSITION TO A SOLUTION THAT IS A LITTLE MORE MOIST BY MID WEEK. HAVE KEPT TEMPS ABOVE GUIDANCE THRU THE EXTENDED...AS THEY LOOKED TOO COOL- ESPECIALLY HIGHS...FOR JUNE UNLESS WE HAVE CONSIDERABLE CLOUDINESS. I EXPECT TEMPS NEAR NORMAL MONDAY THRU THURSDAY...WITH HIGHS IN THE UPPER 70S MTNS AND LOWER TO MID 80S FOOTHILLS AND PIEDMONT. LOWS RANGING FROM THE MID 50S TO LOWER 60S. && .AVIATION /17Z FRIDAY THROUGH TUESDAY/... CONVECTION NOW DEVELOPING OVER THE WESTERN MOUNTAINS AND ALONG THE BLUE RIDGE SHOULD CONTINUE TO EXPAND IN COVERAGE WITH THE PEAK HEATING OF THE DAY. PLENTY OF INSTABILITY ACROSS THE AREA BUT NOT MUCH WIND SHEAR SO STORMS WILL BE "PULSY" IN NATURE. MAINTAINED VCTS WORDING AT ALL TAF SITES BEGINNING IN THE NEXT HOUR OR TWO WITH OVERALL COVERAGE EXPECTED TO BE SCATTERED UNTIL AN HOUR OR TWO AFTER DIURNAL HEATING CEASES AROUND 23Z/7PM TIME FRAME. FOG FORMATION TONIGHT WILL AGAIN BE DEPENDENT ON RESIDUAL CLOUD DEBRIS. MORE CLOUDS MEAN LESS FOG. LESS CLOUDS WILL MEAN MORE FOG. IF FOG DOES FORM IT SHOULD BE PATCHY AND CONFINED TO JUST THE LATE NIGHT HOURS...AND MAYBE AN HOUR OR TWO AFTER DAYBREAK SATURDAY. WIDESPREAD VFR CONDITIONS ARE EXPECTED AGAIN SATURDAY. ASIDE FROM A HIT OR MISS LATE AFTERNOON THUNDERSTORM...NO SIGNIFICANT HAZARDS EXPECTED. A COLD FRONT WILL MOVE THROUGH THE AREA SUNDAY WITH THE POTENTIAL FOR ORGANIZED DEEP CONVECTION. A BROKEN TO SOLID LINE OF THUNDERSTORMS IS EXPECTED TO DEVELOP ALONG THE FRONT...AND THIS WILL LIKELY RESULT IN A 2 TO 3 HOUR PERIOD OF MVFR/IFR CONDITIONS AT EACH TERMINAL WITH ITS PASSAGE. A CHANGE IN AIRMASS WILL TAKE PLACE SUNDAY NIGHT...WHICH SHOULD YIELD VFR CONDITIONS FOR MONDAY INTO TUESDAY WITH LITTLE OR NO THREAT OF DEEP CONVECTION. && .RNK WATCHES/WARNINGS/ADVISORIES...
