AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 815 PM EDT WED JUN 9 2010 .SYNOPSIS... AFTER A COLD FRONT CROSSES THE UPPER OHIO VALLEY TONIGHT...HIGH PRESSURE WILL BUILD AND DRY THE WEATHER FOR THURSDAY AND FRIDAY. RAIN CHANCE WILL RETURN THIS WEEKEND WITH THE ADVANCE OF LOW PRESSURE TOWARD THE GREAT LAKES. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... A COLD FRONT EXTENDING FROM LOW PRESSURE ANALYZED OVER THE WESTERN GREAT LAKES THIS EVENING WILL COMPLETE A CROSSING OF THE REGION TONIGHT. RAIN SHOWERS THAT REMAIN IN ADVANCE OF THAT FEATURE WILL DIMINISH IN COVERAGE THROUGH THE EVENING AND CEASE DURING THE OVERNIGHT WITH DRY ADVECTION AND AS HIGH PRESSURE BEGINS TO BUILD. DESPITE THE LOWERING DEWPOINTS, RESIDUAL MOISTURE AND LACK OF A COOL INFLUX SUPPORTS A LOW TEMPERATURE FORECAST AT, OR A FEW DEGREES ABOVE NORMAL...PRETTY CLOSE TO MOS GUIDANCE. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... HIGH PRESSURE WILL BUILD ON THURSDAY...BECOMING CENTERED OVER THE GREAT LAKES...LEAVING REFRESHING NORTHWEST WIND OVER THE UPPER OHIO VALLEY WITH COMFORTABLE HUMIDITY AND SEASONABLY WARM TEMPERATURES. THE SURFACE HIGH IS PROJECTED RAPIDLY EASTWARD BY FRIDAY WITH INVERTED TROUGH FORECAST OVER THE WESTERN LAKES. THAT BOUNDARY LAYER PATTERN UNDER BROAD RIDGE ALOFT WILL MEAN A WARM CLOSE TO THE WEEK WITH INCREASING HUMIDITY. THE INCREASED INSTABILITY WITH THE ADVANCE OF THE TROUGH ON SATURDAY...WITH SHORTWAVE PROJECTED ACROSS THE RIDGE ALOFT...SUPPORTS THE CHANCE FOR THUNDERSTORMS IN THE WEEKEND FORECAST. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... A FRONTAL BOUNDARY IS EXPECTED TO DRAPE ACROSS THE CWA SUNDAY AFTERNOON...AND REMAIN NEARLY STATIONARY THROUGH MONDAY. THIS BOUNDARY IS EXPECTED TO BE THE FOCUS FOR INTERMITTENT SHOWERS AND THUNDERSTORMS DURING THE BEGINNING OF THE WEEK. SURFACE HIGH PRESSURE IS PROGGED TO BUILD AND PROVIDE DRIER WEATHER FOR MIDWEEK. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... AT TIME OF TAF ISSUANCE MOST TERMINALS REMAINED UNDER IFR CONDITIONS. IFR CONDITIONS ARE EXPECTED TO LIFT WITH THE PASSAGE OF A COLD FRONT DURING THE EVENING HOURS. STILL CANNOT RULE OUT THE POSSIBILITY THAT SOME LOCATIONS MAY SEE MVFR CONDITIONS OVERNIGHT...ESPECIALLY MGW WHERE THE FRONTAL PASSAGE WILL COME LAST...BUT HAVE DECIDED TO GO VFR WITH TAFS AFTER MIDNIGHT. SKIES HAVE GENERALLY CLEARED OUT BEHIND THE COLD FRONT TO THE WEST...AND THINK THAT WINDS AROUND 5 KTS SHOULD ALLOW FOR ENOUGH MIXING TO PREVENT STRATUS/FOG FORMATION. IF WINDS SLACK OFF A BIT...LOW LEVEL MOISTURE FROM RAINFALL TODAY WOULD LIKELY ALLOW FOR RESTRICTIONS TO CONTINUE THROUGH THE REST OF THE NIGHT. SURFACE HIGH WILL BUILD IN FROM THE MIDWEST TO PROVIDE PREVALENT VFR FOR THURSDAY AND FRIDAY. A LOW PRESSURE SYSTEM MOVING NORTHEAST FROM TEXAS WILL BRING SHOWERS AND THUNDERSTORMS WITH THE POTENTIAL FOR MVFR/IFR RESTRICTIONS FOR THE WEEKEND INTO MONDAY. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...NONE. OH...NONE. PA...NONE. WV...NONE. &&
