AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON WV 150 PM EDT SAT JUL 11 2009 .SYNOPSIS... A COLD FRONT ARRIVES TODAY...BECOMING STATIONARY JUST SOUTH OF WEST VIRGINIA INTO EARLY NEXT WEEK. HIGH PRESSURE TUESDAY. && .NEAR TERM /THROUGH TONIGHT/... SHOWERS/STORMS CONTINUE TO TREK ACROSS WEST VIRGINIA THIS MORNING...LIKELY AIDED BY WEAK DISTURBANCE IN THE MIDLEVEL FLOW. DO NOT EXPECT THESE STORMS TO BE SEVERE...AND THEY WILL DEPART OVER THE NEXT FEW HOURS. CLEAR SLOT BEHIND THE STORMS WILL ALLOW FOR DESTABILIZATION AHEAD OF FRONTAL BOUNDARY. COULD SEE PREFRONTAL STORMS IMPACT OUR SOUTHEAST OHIO COUNTIES AS EARLY AS 16Z. MIDLEVEL FLOW WILL BE INCREASING. UP TO 2000 J/KG OF CAPE WHICH IS FORECAST TO DEVELOP...AND MODEL SOUNDINGS INDICATE DRY MIDLEVEL AIR. WITH FREEZING LEVELS RELATIVELY HIGH...LOOKING MORE LIKE A WIND THREAT THAN A HAIL THREAT FOR THE AFTERNOON. KEEPING LIKELY POPS IN THE NORTHERN COUNTIES FOR NOW...BUT WILL AMEND AS NEEDED. COULD BE A BUMPY RIDE FOR SOUTHEAST OHIO AND NORTHERN WEST VIRGINIA LATER TODAY. TEMPERATURES TWEAKED. && .SHORT TERM /SUNDAY THROUGH TUESDAY/... WEAK HIGH PRESSURE WILL WAGE A BATTLE AGAINST A STUBBORN COLD FRONT THAT WILL BE REACHING ITS SOUTHWARD EXTENT...EFFECTIVELY KEEPING THE COAL FIELDS UNDER THE THREAT FOR SCATTERED SHOWERS AND THUNDERSTORMS WHILE THE NORTHERN ZONES LOOK TO BE DRY. NORTHWEST FLOW ALOFT CONTINUES NECESSITATING THE WATCH FOR VORT MAXES EMBEDDED WITHIN THE FLOW. ALONG THE STATIONARY BOUNDARY...SURFACE LOW PRESSURE APPROACHES FROM KENTUCKY SUNDAY NIGHT AND MONDAY. THIS WILL PUSH SCATTERED SHOWERS BACK NORTH INTO CENTRAL WEST VIRGINIA. HIGH PRESSURE BUILDS IN ONCE AGAIN ACROSS THE NORTH INTO TUESDAY...WITH ONLY SOME HIGH CLOUDS TO DEAL WITH IN THE NORTHWEST FLOW...BUT LOOKING TO BE CONVECTION FREE OTHERWISE FOR THE END OF THE SHORT TERM PERIOD. BLENDED THE MET...SREF...AND MOSGUIDE BIAS CORRECTED NUMBER FOR THE TEMPERATURES GENERALLY...USING THESE AS A STARTING POINT. OVERALL TREND LOOKS TO BE NEAR NORMAL FOR MID SUMMER. && .LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/... GENERALLY FOLLOWING HPC GUIDANCE. STATIONARY FRONT TO THE SOUTH WEAKENS SO THAT DRIER AND SLIGHTLY COOLER WEATHER WILL GRADUALLY TAKE OVER LATER MONDAY AND TUESDAY. DOWNGRADED OUR CHANCE POPS MONDAY TO SLIGHT CHANCE...KEEPING SLIGHT CHANCE ONLY BECAUSE SOME MODELS SHOW AN UPPER DISTURBANCE DROPPING ACROSS THE AREA. HPC THINKS THE MONDAY FEATURE IS WAY OVERDONE WITH FEEDBACK PROBLEMS. THE VERY WEAK FRONT THEN LIFTS BACK NORTH BY WEDNESDAY...WITH LITTLE FANFARE. AN AREA OF LOW PRESSURE AND COLD FRONT WILL DROP SOUTHEAST OVER THE WESTERN UPPER RIDGE AND ACROSS OUR AREA LATER WEDNESDAY AND THURSDAY. THIS WILL BRING MORE SHOWERS AND THUNDERSTORMS...ALONG WITH WARMER AND MORE HUMID AIR BY MIDWEEK. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... 12Z SATURDAY THROUGH 12Z SUNDAY... VARIABLE CONDITIONS TODAY...HONESTLY NOT THE BEST DAY TO FLY. SCT-BKN CU FORMING UNDERNEATH CI VEIL CURRENTLY...WITH CIGS IN MVFR RANGE AT TIMES. EARLIER SHRA/TSRA ACTIVITY IS CROSSING MOUNTAINS AT THIS TIME. HOWEVER...ACTIVITY ASSOCIATED WITH COLD FRONT WILL BE DROPPING IN DURING THE LATE AFTERNOON/EARLY EVENING HOURS. WENT WITH PREVAILING MVFR CONDITIONS FOR A TIME AT MOST TAF LOCATIONS...BUT BRIEF PERIODS OF IFR CERTAINLY EXPECTED IN THE HEAVIEST SHOWERS/STORMS. WATCH OUT FOR WIND GUSTS OF UP TO 30 KNOTS NEAR ANY STORM. COVERAGE OF RAIN SHOULD TAIL OFF A BIT AFTER SUNSET BUT SCATTERED SHRA AND A FEW THUNDERSTORMS WILL LIKELY CONTINUE AHEAD OF THE FRONT. THE BOUNDARY WILL SINK INTO CENTRAL WEST VIRGINIA BY 06Z...BUT SLOW TO A CRAWL THEREAFTER. TAF SITES SHOULD BE FREE OF RAINFALL FOR THE MOST PART BY 12Z AND AFTER...ALTHOUGH FAR SOUTHERN WEST VIRGINIA AND SOUTHWEST VIRGINIA WILL STILL BE UNDER THE GUN. PATCHY FOG EXPECTED AT ANY LOCATION THAT CAN CLEAR OUT TOWARDS SUNRISE. MOST SITES WILL ACHIEVE VFR CONDITIONS ONCE AGAIN BY 14Z OR SO. AFTER 18Z SUNDAY... IFR POSSIBLE EARLY MONDAY MORNING DUE TO FOG. && .RLX WATCHES/WARNINGS/ADVISORIES... WV...NONE. OH...NONE. KY...NONE.
