NWS Charleston, WV wrote its last area forecast discussion before the first event at Jun 17, 7:05 PM EST, 1 hour 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON WV 805 PM EDT SUN JUN 17 2012 .SYNOPSIS... UPPER LEVEL WAVE MOVES THROUGH TONIGHT...AND ANOTHER ON MONDAY. UPPER LEVEL RIDGE ALLOWS FOR BUILDING HEAT THRU MID WEEK. COLD FRONT PUSHES SOUTH FRIDAY...BECOMING STATIONARY ACROSS THE SOUTH. && .NEAR TERM /THROUGH MONDAY/... 730PM UPDATE... SCT CONVECTION BEGINNING TO WANE ACROSS THE AREA WITH LOSS OF HEATING AND MANY AREAS ACROSS THE WEST IN MORE OF A STABLE WORKED OVER AIRMASS. FINESSED POPS OVERNIGHT BASED ON CURRENT RADAR TRENDS...DROPPING SIGNIFICANTLY OVERNIGHT. HOWEVER WITH UPR TROF AXIS WORKING THRU...DID LEAVE HIGH CHC ACROSS NORTHERN LOWLANDS INTO NORTHERN MTNS THIS EVENING. MODELS SHOW RESIDUAL LIFT ARND H7 TRAILING THRU CENTRAL WV LOWLANDS BACK INTO NE KY LATE TONIGHT AND HAVE LEFT SOME LOW CHC POPS THERE. MAY SEE LOW STRATUS DEVELOP AFTER MIDNIGHT ALONG AND NORTH OF I64 WITH AREAS OF FG THROWN IN...ESPECIALLY WHERE IT HAS RAINED. HOWEVER...WITH AREAS OF STRATUS AND 25 TO 30 KT FLOW AT H925...THINK WIDESPREAD DENSE FG IS LESS OF A FACTOR. PREVIOUS DISCUSSION BELOW... SEVERAL LINES OF CONVECTION WILL BE MOVING ACROSS THE CWA OVER THE NEAR TERM PERIOD. THE FIRST IS CURRENTLY JUST EAST OF CRW AND APPEARS TO BE ROOTED ALONG A WEAKENING DEWPOINT GRADIENT. IT HAS BEEN FALLING APART OVER THE LAST SEVERAL HOURS. STILL...EVERY ONCE IN A WHILE A CELL POPS UP ALONG THIS LINE...AND AS IT RUNS INTO THE MOUNTAINS COULD SEE SOME LOCAL ENHANCEMENT THERE TOO. THE NEXT LINE OF CONVECTION IS CURRENTLY ENTERING THE CWA FROM THE WEST. THIS LINE IS TIED TO A WEAK UPPER LEVEL SHORTWAVE AHEAD OF THE MAIN SHORTWAVE...WHICH IS THE THIRD LINE OF CONVECTION ON REGIONAL RADAR...CURRENTLY RUNNING FROM WESTERN LAKE ERIE DOWN TOWARDS CINCINNATI. VISIBLE SATELLITE SHOWS SOME BREAKS IN THE CLOUDS BETWEEN EACH LINE...WHICH MAY HELP ADD ENOUGH TO THE INSTABILITY TO KEEP THE STORMS SURFACE BASED A BIT LONGER. DID SEE ONE GUST AROUND 30KTS AT KCMH WITH THE LINE THAT IS CURRENTLY ENTERING OUR CWA...SO WHILE NOT REAL IMPRESSED WITH SEVERE POSSIBILITIES...COULD STILL GET SOME MODERATE TO STRONG WINDS GUSTS OUT OF THE STRONGEST STORMS. LOCALIZED HEAVY RAINFALL WILL ALSO BE POSSIBLE. ITS HARD EXACTLY TO TIME OUT EACH LINE WITH HOW CLOSE THEY ARE TO EACH OTHER...SO GENERALLY WENT WITH CHANCE TO LIKELY POPS MOVING THROUGH TODAY THROUGH TONIGHT. ONE MORE TRAILING PIECE OF UPPER LEVEL ENERGY WILL MOVE THROUGH MONDAY AS AN UPPER RIDGE BEGINS TO BUILD BACK IN...SO CHANCE POPS CONTINUE...ESPECIALLY ACROSS NORTHERN HALF OF CWA. MIXED IN MET GUIDANCE FOR OVERNIGHT LOWS...WHICH RESULTED IN LITTLE CHANGE TO PREVIOUS FORECAST. MONDAYS HIGHS ARE A BIT MORE TRICKY...NAM SHOWS WARMING 850S AS THE UPPER RIDGE BUILDS...BUT STILL LOOKING AT CLOUDS/PRECIP HANGING AROUND. COOLED MONDAYS HIGHS BY BLENDING IN BIAS-CORRECTED MET GUIDANCE...WHICH RESULTS IN THE WARMEST HIGHS IN THE TRI-STATE AREA...AND THEN COOLER TO THE NORTH AND EAST. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... KEPT LINGERING SHOWERS EXITING OUR EASTERN MOUNTAINS...AS A BUILDING RIDGE ALOFT BUILDS FROM THE WEST AND SOUTH...AND A SURFACE HIGH BUILDS ACROSS THE MID ATLANTIC STATES...WEST INTO THE APPALACHIANS MONDAY NIGHT. EXPECT DRY CONDITIONS MAINLY LOWLANDS ON TUESDAY THROUGH THURSDAY...WITH THE EXCEPTIONS OF ISOLATED AFTERNOON STORMS DEVELOPING ALONG THE EASTERN ELEVATED HEAT SOURCES...AND DYING OFF SHORTLY AFTER SUNSET. ALLOWED CHANCE POPS AHEAD OF AN APPROACHING FRONT...AND THE AFOREMENTIONED DIURNAL HEATING MAINLY ALONG THE OH RIVER ON THURSDAY. MODELS CONTINUE SHOWING H85 TEMPERATURES REACHING 20C AT 00Z WED THRU 00Z FRI. IN ADDITION...SKY COVER GUIDANCE SHOW MOSTLY CLEAR TO PARTLY CLOUDY SKIES...TO PRODUCE DESCENT AMOUNT OF SUNSHINE...ALLOWING AFTERNOON TEMPERATURES TO REACH THE MID TO LOWER 90S THRU THE SAME TIME FRAME. USED MOSTLY BIAS CORRECTED MOS RAW THRU THE PERIOD. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... A COLD FRONT PUSHES SOUTH EARLY FRIDAY WITH FRESHER AIR MASS MOVING IN UNDER NORTHWEST FLOW. THIS FRONT COULD BECOME STATIONARY AS IT WEAKENS ACROSS OUR SOUTHERN COAL FIELDS THROUGH THE WEEKEND. LOWERED HIGH TEMPS FOR FRIDAY AND SATURDAY AS FLOW BECOMES NORTHWEST ALOFT PER ECMWF...ALIGNED WITH A BLEND OF HPC WITH THE GMOS GUIDANCE. LET SLIGHT CHANCE POPS TO COVER FOR UNCERTAINTY ON PCPN DURING THE AT LAST 48 HOURS OF THE PERIOD. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... LOOKING AT VFR CONDITIONS OUTSIDE OF SCT SHRA/TSRA ASSOCIATED WITH UPR TROF MOVING THRU. HAVE SOME TEMPO GROUPS TO COVER THIS IN TAFS NEXT FEW HRS BASED ON RADAR TRENDS. ACTIVITY SHOULD BECOME MORE ISOLATED IN NATURE BY 06Z. FOG IS A TRICKY FORECAST TONIGHT...WITH MDLS SHOWING 25 TO 30 KTS OF FLOW IN BL. THIS MAY RESULT IN MORE STRATUS THAN WIDESPREAD FG. HOWEVER ON THE OTHER HAND...SEVERAL OF TAF SITES HAVE RECEIVED RAINFALL THIS AFTN AND EARLY EVE WHICH WILL THROW A WRENCH IN THINGS. WITH DEEPER MOISTURE SLATED TO MOVE EAST OUT OF AREA BY 09Z...EXPECT LOW STRATUS TO ALREADY HAVE FORMED ACROSS NE KY/SE OH INTO WESTERN WV LOWLANDS AND HAVE CODED UP MVFR AND IFR CIGS FOR KHTS...KCRW...KPKB...WITH KHTS SLATED FOR IFR CIGS. KEPT FG IN MVFR RANGE GIVEN FLOW IN BL BUT DID ALLOW FOR SOME IFR CIGS FOR SITES THAT HAVE RECEIVED MOST RAINFALL...IE KHTS. THINK KEKN WILL BE THE EXCEPTION WITH LIFR FG AND STRATUS DEVELOPING AFTER 09Z WITH DEPARTURE OF DEEPER MOISTURE. FG AND STRATUS WILL BE SLOW TO BURN OFF...WITH FG LIFTING BY 13Z AND STRATUS BREAKING UP BY 15Z FOR A RETURN TO LOW END VFR CONDITIONS FOR TAF SITES. BKN CU FROM HEATING BY LATE MORNING MAY GET DOWN INTO MVFR RANGE BUT KEPT LOW END VFR FOR NOW. ISO TO SCT SHRA/TSRA IN AFTN AND HAVE VCTS IN TAF SITES TO COVER AT THIS DISTANCE. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z TUESDAY... FORECAST CONFIDENCE: LOW. ALTERNATE SCENARIOS: FORMATION AND DENSITY OF FOG TONIGHT WILL GREATLY DEPEND ON WHEN AND WHERE SHOWERS FALL. STRATUS MAY BE LESS ABUNDANT THAN FORECAST WHICH MAY RESULT IN MORE FOG.
