NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Jun 18, 3:04 PM EST, 4 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 404 PM EDT MON JUN 18 2012 .SYNOPSIS... A WEAK UPPER LEVEL DISTURBANCE WILL PASS OVERHEAD TODAY EXITING THE AREA TONIGHT. HIGH PRESSURE ALOFT WILL STRENGTHEN OVER THE AREA BY MID WEEK...RESULTING IN A WARMING TREND AND HUMID CONDITIONS FOR THE REMAINDER OF THE WEEK. && .NEAR TERM /THROUGH TUESDAY/... AS OF 1130 AM EDT MONDAY... SCATTERED SHOWERS IN THE EASTERN COUNTY WARNING AREA WILL CONTINUE TO MOVE SOUTHEAST. SHOWERS AND THUNDERSTORMS IN SOUTHEAST WEST VIRGINIA WILL MOVE SOUTHEAST AND WILL TRIGGER MORE STORMS OVER THE MOUNTAINS THIS AFTERNOON. RAISED MAXIMUM TEMPERATURES FOR SOME LOCATIONS WEST OF THE BLUE RIDGE BASED ON CURRENT TRENDS IN OBSERVATIONS. AS OF 430 AM EDT MONDAY... A WEAK UPPER LEVEL DISTURBANCE WILL PASS OVERHEAD TODAY EXITING THE AREA TONIGHT. THIS FEATURE WILL RESULT IN CONSIDERABLE CLOUDINESS ALONG WITH SCATTERED SHOWERS AND STORMS OVER THE REGION TODAY. VORT AXIS IS ALONG THE ALLEGHANY FRONT THIS MORNING...AND IS FORECAST TO SLOWLY MOVE EAST...EXITING THE CWA BY THIS EVENING. MODEL POPS ARE HIGHEST THIS MORNING...THEN WANE THIS AFTERNOON. ANY CLEARING HOWEVER MAY RESULT IN INCREASED INSTABILITY...MODIFIED SOUNDING CAPES 1000 ISH...FUELING ADDITIONAL SHRA/TSRA DURING THE AFTERNOON/EVENING. ANY INSTABILITY DRIVEN ACTIVITY SHOULD DISSIPATE AFTER SUNSET. TEMPS TODAY WILL AGAIN BE SIMILAR TO THE LAST FEW DAYS...READINGS MAINLY IN THE 70S...BUT TESTING L80S FOR A FEW HOURS DURING THE MID/LATE AFTERNOON. MOST NOTICABLE DIFFERENCE TODAY COMPARED TO THE LAST FEW DAYS WILL BE THE MOISTURE CONTENT OF THE AIRMASS...DEWPOINTS NOW INTO THE L60S...COMFORT FACTOR EDGING DOWN. THESE HIGHER DEWPOINTS WILL ALSO SUPPORT HIGHER TMINS...TONIGHTS LOWS AOA 60. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... AS OF 345 PM EDT MONDAY... AN UPPER LEVEL DOME OF HIGH PRESSURE...BUILDING IN FROM THE CENTRAL GULF COAST REGION...WILL BE THE DOMINANT FEATURE OF OUR WEATHER PATTERN THROUGH THE MIDDLE OF THE WEEK. AS SUCH...THIS UPPER LEVEL HIGH PRESSURE WILL HELP WARM TEMPERATURES ACROSS OUR AREA TO THOSE MORE COMMONLY FOUND DURING MID TO LATE SUMMER...WITH WEDNESDAY AND THURSDAY AFTERNOON HIGHS RANGING FROM THE MID TO UPPER 80S ACROSS THE MOUNTAINS...AND FROM THE LOW TO MID 90S ACROSS THE PIEDMONTS. OVERNIGHT LOWS WILL HOLD IN THE 60S ACROSS MOST OF THE AREA. THIS UPPER LEVEL HIGH PRESSURE WILL ALSO HAVE A STABILIZING EFFECT ON OUR ATMOSPHERE...HELPING TO STRICTLY LIMIT THE DEVELOPMENT OF ANY SHOWERS OR THUNDERSTORMS ACROSS THE PIEDMONT REGION. HOWEVER... DIFFERENTIAL HEATING AND LOW LEVEL WIND CONVERGENCE ALONG SOME OF THE HIGHER RIDGELINES WILL LIKELY BECOME STRONG ENOUGH EACH AFTERNOON TO ALLOW A FEW THUNDERSTORMS TO DEVELOP OVER THE MOUNTAINS. ONE OR TWO OF THESE STORMS MAY BECOME STRONG FROM TIME TO TIME...BUT WITH NO REAL SUPPORT IN THE UPPER LEVELS OF THE ATMOSPHERE...ANY STORMS WHICH DO DEVELOP WILL NOT STAY STRONG FOR EXTENDED PERIODS OF TIME. SHOWER AND THUNDERSTORM ACTIVITY SHOULD FADE QUICKLY EACH EVENING AFTER SUNSET. && .LONG TERM /FRIDAY THROUGH SUNDAY/... AS OF 345 PM EDT MONDAY... THE MAIN FEATURE TO KEEP AN EYE ON DURING THE LONGTERM PERIOD WILL BE A COLD FRONT THAT WILL PASS THROUGH THE AREA ON FRIDAY AND EARLY SATURDAY MORNING. THIS FRONT WILL BRING MORE WIDESPREAD SHOWERS AND THUNDERSTORMS TO THE AREA DURING THE EARLY HALF OF THE WEEKEND... BEFORE MOVING TO THE SOUTHEAST BY SATURDAY AFTERNOON. NORTHWESTERLY FLOW TAKES OVER DURING THE LATER HALF OF THE WEEKEND AS AN UPPER LEVEL TROUGH SETS UP OVER THE HUDSON BAY OF CANADA...SO WILL HAVE TO KEEP AN EYE ON UPPER LEVEL DISTURBANCES PUSHING INTO OUR AREA FROM THE GREAT LAKES REGION. TEMPERATURES WILL BE A LITTLE COOLER BEHIND THE COLD FRONT...BUT WILL REMAIN SUMMERLIKE WITH HIGHS RANGING FROM THE MID 80S WEST...TO THE LOW 90S EAST. && .AVIATION /20Z MONDAY THROUGH SATURDAY/... AS OF 130 PM EDT MONDAY... SCATTERED THUNDERSTORMS THIS AFTERNOON WERE FORMING ALONG THE BLUE RIDGE. THE STORMS WILL IMPACT ROA...LWB AND BCB AROUND THE START OF THE 18Z TAF PERIOD THEN LYH AND DAN BEFORE 22Z. EXPECT COVERAGE AND INTENSITY OF STORMS TO DIMINISH AFTER SUNSET. SURFACE DEW POINTS WILL BE IN THE UPPER 50S TO MID 60S. MODERATE TO HIGH CONFIDENCE OF MVFR FOG IN THE WESTERN VALLEYS OVERNIGHT...ESPECIALLY IN LOCATIONS THAT GET RAIN THIS AFTERNOON. TUESDAY THROUGH FRIDAY...THERE IS A CHANCE FOR WIDELY SCATTERED AFTERNOON/EVENING SHRA/TSRA...ESPCLY OVER THE MTNS...BUT LIMITED COVERAGE SHOULD BE NAVIGABLE. A WEAK COLD FRONT DROPPING IN FROM THE NW MAY BRING SLIGHTLY BETTER COVERAGE OF SHRA/TSRA BY THE END OF THE WEEK. LATE NIGHT MVFR TO IFR VALLEY OR RIVER VALLEY FOG ARE POSSIBLE AROUND DAYBREAK EACH MORNING...BUT MAINLY IN THE MOUNTAINS. ANY FOG FORMATION SHOULD BE LIMITED TO A FEW HOURS NEAR DAYBREAK... DISSIPATING QUICKLY AFTER SUNRISE. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...NONE. NC...NONE. WV...NONE. && SYNOPSIS...PM NEAR TERM...AMS/NF SHORT TERM...NF LONG TERM...RCS AVIATION...AMS/PM
