AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 944 PM EDT WED AUG 29 2007 .SYNOPSIS... HIGH PRESSURE OFF THE MID ATLANTIC COAST WILL CONTINUE TO RIDGE SOUTHWEST INTO THE REGION TONIGHT INTO THURSDAY. A COLD FRONT WILL APPROACH THE AREA FROM THE NORTHWEST FRIDAY AND SLOWLY SLIDE SOUTH INTO NORTH CAROLINA ON SATURDAY. COOLER HIGH PRESSURE SHOULD BUILD IN BEHIND THE FRONT FROM THE NORTH LATER IN THE WEEKEND BRINGING A RETURN TO DRIER WEATHER INTO EARLY NEXT WEEK. && .NEAR TERM /THROUGH THURSDAY/... WATER VAPOR SHOWS A WEAK VORT MAX CROSSING THE CENTRAL APPALACHIANS AT THIS TIME. THE 00Z RNK SOUNDING SHOWED WEAK TO MODERATE INSTABILITY WITH 1100 CAPE AND ONLY WEAK CIN AS OF 00Z. ISOLD SHOWERS ARE POPPING UP ACROSS THE MTNS OF SW VA AT THIS TIME...AND I THINK THEY WILL CONTINUE THROUGH AT LEAST MIDNIGHT AND THEN WIND DOWN. SO I HAVE EXTENDED THE AREA OF COVERAGE FOR ISOLD SHOWERS/TSTMS...AND TAPER THEM OFF MORE SLOWLY THAN THE PREVIOUS FCST. ONLY OTHER CHANGE WAS TO LOWER MIN TEMPS A FEW DEGREES IN VALLEYS CLOSER TO THE CURRENT DEWPOINTS. FOG WILL PROB FORM AGAIN IN THE VALLEYS...ALTHOUGH MAYBE NOT TO THE EXTENT OF YESTERDAY IN THE BCB-ROA-PSK CORRIDOR IF SHWRS DO NOT DEVELOP. MODELS CONTINUE TO SHOW LITTLE IF ANY QPF WITH UPPER AIR DISTURBANCE... BOUNDARY APPROACHING FROM THE NW LATE DAY FRIDAY. JUST TOO MUCH INSTABILITY TO IGNORE STORM CHCS LATE DAY THURSDAY. FIGURE MAX T WILL BE AT OR A FEW DEGREES ABOVE TODAYS LEVELS...EXCEPT IN THE EXTREME WEST WHERE CLDS MAY HOLD TEMPS DOWN A BIT. WENT AT LEAST A FEW DEGREES ABV WARMEST GUIDANCE OVERNIGHT TONIGHT...AS MOS CONTINUES TO BUST ON THE COOL SIDE IN THIS REGIME. && .SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/... EXPECT ANY LINGERING PREFRONTAL CONVECTION TO BE CONFINED MAINLY OVER THE WEST THURSDAY EVENING BEFORE LOSS OF HEATING CAUSES RESIDUAL TSRA BAND TO FADE. SINCE MODELS A LITTLE SLOWER SHIFTED HIGHER CHANCE POPS WEST OF THE BLUE RIDGE THURSDAY EVENING AND MAINLY ALONG THE BLUE RIDGE OVERNIGHT...OTRW PC. COLD FRONT SHOULD BE NEAR THE BLUE RIDGE FRIDAY WITH TRAILING 850 MB THETA-E GRADIENT NEARING THE REGION LATE IN THE DAY. MODELS SHOW RIBBON OF HIGHER PWAT AS WELL NEAR THE BLUE RIDGE ALONG WITH WEAK AFTERNOON INSTABILITY AHEAD OF UPSTREAM S/W AXIS. CONVERGENCE ALSO APPEARS STRONG ENOUGH TO SUPPORT REDEVELOPMENT OF A BROKEN BAND OF CONVECTION SO UPPED POPS EASTERN SLOPES WITH SLIGHT CHANCES FAR NW AND SE PIEDMONT FOR NOW. LOOKS LIKE AXIS OF TSRA WILL SLIDE TO THE SE WITH 850 MB FRONT FRIDAY NIGHT BEFORE WEAKENING OVER NORTHERN NC OVERNIGHT INTO EARLY SAT. THUS GOING WITH CHANCE POPS SE FRIDAY EVENING WITH SLIGHT CHANCE ESLWHERE WITH SOME POST FRONTAL CLEARING NW. A BIT TRICKY AS TO NORTHWARD EXTENT OF RESIDUAL DEEP MOISTURE SAT WITH DEEPENING NE FLOW DEVELOPING AND SURFACE FRONT WELL SOUTH. GUIDANCE HINTING AT STUCK LEFTOVER RH NW NC PER UPSLOPISH FLOW SO LEAVING LOW POPS NC SIDE INTO FAR SW VA THRU SAT AFTERNOON AT THIS POINT. SURFACE HIGH WEDGES IN FROM THE NE A BIT MORE SAT NIGHT BASICALLY ENDING SHRA THREAT ALTHO WILL NEED TO WATCH POTENTIAL FOR LOW CLOUDS ESPCLY SW/SOUTHERN ZONES OVERNIGHT. FOLLOWING CLOSER TO WARMER MAV MOS FOR HIGHS SINCE THINK THE NAM A BIT WET WHILE LEANING SIMILAR TO THE MET LOW TEMP VALUES AT NIGHT WHICH HAVE BEEN BEST OF LATE. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... THE SURFACE COLD FRONT WILL BE WELL TO THE SOUTH BY SUNDAY WITH DRIER/COOLER AIR WEDGING SOUTH INTO THE AREA IN RESPONSE TO DECENT SURFACE HIGH RIDGING SW FROM OFF THE MID ATLC COAST. THIS SHOULD SET THINGS UP FOR A MAINLY SUNNY AND COOLER DAY ON SUNDAY. SURFACE HIGH WILL THEN SHIFT OFFSHORE EARLY NEXT WEEK ALLOWING A BRIEF PERIOD OF RETURN FLOW TO SETUP AHEAD OF ANOTHER WEAK DRY COOL FRONT SET TO DROP THROUGH BY MIDWEEK. HOWEVER ANY MOISTURE LOOKS QUITE SHALLOW GIVEN CUTOFF OF RH TRANSPORT BY GULF STATES CONVECTION SO PLANNING TO LEAVE OUT ANY OROGRAPHIC SHRA NW NC RIDGES ON MONDAY FOR NOW. BOTH GFS/ECMWF SHOW STRONGER UPPER RIDGE SLIDING BACK INTO THE SE STATES TUE/WED WITH ANOTHER ROUND OF INCREASING 850 MB TEMPS IN STORE. THIS SHOULD AGAIN CAP OFF ANY TSRA CHANCES SO KEEPING THE REST OF THE EXTENDED DRY AS WELL WITH MAINLY SUNNY/CLEAR SKIES AND QUITE DRY CONDITIONS IN PLACE. TEMPS SHOULD COOL BACK CLOSER TO NORMAL LEVELS EARLY ON WITH COMFORTABLE LOWS THRU EARLY WEEK. THINK COMBO OF ONLY WEAK SURFACE HIGH TO THE NORTH...DRY GROUND...AND PLENTY OF SUN UNDER TOASTY 850 MB VALUES WILL MAKE FOR ABOVE GUIDANCE HIGHS BY MIDWEEK WITH MORE UPPER 80S/LOW 90S LIKELY. && .AVIATION /02Z THURSDAY THROUGH MONDAY/... LOW LEVEL MOISTURE WITH EASTERLY FLOW WILL BRING BACK LOW CLOUD DECK AND FOG TO AREAS ALONG AND EAST OF THE BLUE RIDGE LATE TONIGHT. IFR FOG POSSIBLE IN MOUNTAIN VALLEYS...ESPECIALLY IN THE MOUNTAIN EMPIRE OF SOUTHWEST VIRGINIA AND NORTHWEST NORTH CAROLINA MOUNTAINS AND FOOTHILLS WHERE ISOLATED THUNDERSTORMS DEVELOPED THIS AFTERNOON. ANY CLOUDS AND FOG WILL BURN OFF BY MID MORNING FOR THE AREA TO RETURN TO VFR CONDITIONS. PREFRONTAL SHORT WAVE ENTERS THE AREA THURSDAY MORNING WHICH WILL BRING THUNDERSTORMS TO THE AREA DURING THE AFTERNOON AND EVENING. COLD FRONT WILL DISSIPATE BEFORE CROSSING CENTRAL VA THUR NIGHT...BUT ENOUGH OF IT WILL REMAIN FOR STORMS SE OF LWB THROUGH THE AFTERNOON FRIDAY...WITH TEMPO IFR CONDITIONS IF TERMINALS TAKE DIRECT HITS. AS HIGH PRESSURE CROSSES INTO THE MIDDLE ATLANTIC THIS WEEKEND...LYH MAY EXPERIENCE A FEW MORNINGS OF IFR CIGS AFTER MIDNIGHT EACH DAY WITH STRONG NE FLOW DEVELOPING. && .RNK WATCHES/WARNINGS/ADVISORIES...
