AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 321 PM EDT SUN JUN 8 2014 .SYNOPSIS... AFTER SHOWERS AND THUNDERSTORMS DURING THE LATE AFTERNOON AND EVENING...MONDAY IS EXPECTED TO BE DRY. THE CHANCE OF SHOWERS AND THUNDERSTORMS WILL RETURN TO THE FORECAST ON TUESDAY AND LAST THROUGH FRIDAY. && .NEAR TERM /THROUGH MONDAY/... LOW PRESSURE OVER CENTRAL OHIO WILL CONTINUE TO PULL TO THE NORTHEAST. WIDESPREAD SHOWERS WITH EMBEDDED THUNDERSTORMS HAVE BLOSSOMED OVER THE REGION...WITH THIS ACTIVITY EXPECTED TO CONTINUE INTO THE EVENING HOURS. IF ANY SEVERE THUNDERSTORM ACTIVITY DEVELOPS...STRONG WINDS WOULD BE THE BIGGEST CONCERN DUE TO DEEPER SHEAR MOVING INTO THE REGION. BULK OF PRECIPITATION SHOULD CLEAR EASTERN OHIO AND THE NORTHERN WEST VIRGINIA PANHANDLE BY SUNSET...WITH THE REST OF THE REGION DRYING OUT BY MIDNIGHT. EVEN AS PRECIPITATION ENDS...NOT MUCH DRY AIR WILL MOVE INTO THE REGION...WITH ANY CLEARING LIKELY LIMITED TO OHIO COUNTIES. REST OF THE REGION WILL REMAIN CLOUDY OVERNIGHT...WITH CLOUDS CONTINUING INTO MONDAY. WITH THE LOW FILLING AS IT MOVES INTO EASTERN PENNSYLVANIA...HAVE PULLED THE CHANCE OF RAIN ACROSS EASTERN COUNTIES WITH LITTLE SUPPORT FOR PRECIPITATION TO CONTINUE. CONSIDERING CLOUD COVER...OHIO COUNTIES WILL EXPERIENCE A BIGGER SWING IN TEMPERATURES OVER THE NEXT 24 HOURS DUE TO GREATER RADIATIONAL COOLING TONIGHT AND MORE SUNSHINE ON MONDAY. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... UPPER LEVEL TROUGH CURRENTLY ACROSS THE ROCKIES WILL BE THE MAIN WEATHER PLAYER FOR THE MIDDLE OF THE WEEK. AS THIS TROUGH MOVES SLOWLY EASTWARD...IT WILL SPAWN A SURFACE LOW ACROSS TEXAS THAT WILL SHIFT TO THE NORTHEAST. BY TUESDAY MORNING A WARM FRONT WILL LIE JUST SOUTH OF THE MASON-DIXON LINE AND MOVE NORTH TUESDAY AND TUESDAY NIGHT. WHILE THE FRONT WILL HAVE PLENTY OF MOISTURE TO WORK WITH...STILL UNSURE AS TO JUST HOW STRONG THE FORCING WILL BE FOR PRECIPITATION. ON WEDNESDAY THE LOW WILL SHIFT FROM SOUTHERN INDIANA TOWARDS MICHIGAN. HAVE KEPT CHANCE POPS IN THE FORECAST THROUGH MUCH OF THIS TIME PERIOD WITH A LACK OF CONFIDENCE TO COMMIT TO LIKELY POPS AT ANY GIVEN TIME. EXPECT TEMPERATURES TO BE ABOVE NORMAL THROUGH THE PERIOD. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... FOR THE MOST PART...THE DETERMINISTIC MODELS CONTINUE TO REMAIN CLOSE TO EACH OTHER IN RESPECT TO THE UPPER LEVEL PATTERN...LIFTING A 500MB LOW NORTHWARD TOWARDS THE GREAT LAKES THROUGH FRIDAY. AND AT THE SAME TIME DRAGGING A SURFACE FRONT SLOWLY CROSS THE REGION. HOWEVER...THERE SEEM TO BE SOME INHERENT DIFFERENCES IN HOW THE MODELS HANDLE SHORTWAVES WITHIN THE FLOW FRIDAY...WITH THE NEWEST GFS BRINGING IN ANOTHER SHORTWAVE AND LINGERING PRECIPITATION A BIT LONGER THAN THE PREVIOUS RUNS. WILL NEGLECT THIS FOR NOW AND END PRECIP CHANCES BY FRIDAY EVENING AS HIGH PRESSURE BUILDS OVERHEAD. WENT WITH A BLEND OF HPC GUIDANCE/MEX VALUES FOR TEMPS THROUGH THE PERIOD...WHICH KEPT HIGHS NEAR SEASONAL VALUES. && .AVIATION /20Z SUNDAY THROUGH FRIDAY/... FURTHER SHWR AND TSTM DVLPMNT IN CONJUNCTION WITH ENCROACHING STRATOCU...AND EVENTUAL FOG AND ST TNGT...WL CONTRIBUTE TO DETERIORATED CONDITIONS THROUGH TNGT. IFR WL INTIALLY BE LTD TO TSTMS...BUT MORE WIDESPREAD POTENTIAL IS POSSIBLE TNGT AS WEAK CDFNT SLIDES ACRS THE REGION IN THE WAKE OF TDAS LOW PRES CROSSING. VARIABLE SFC WND IS ASSOCIATION WITH THE CROSSING LOW PRES WL TAKE ON A MORE WNWLY COMPONENT WITH PASSAGE OF THE SYSTEM THIS EVE. .OUTLOOK.../MONDAY THROUGH THURSDAY/...
