AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 915 PM EDT SAT JUN 12 2010 .SYNOPSIS... WITH THE AREA IN A WARM AND MOIST AIR MASS...SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE THROUGH EARLY NEXT WEEK. HIGH PRESSURE WILL BUILD IN BRIEFLY ON TUESDAY BEFORE ANOTHER WARM FRONT LIFTS INTO THE AREA FOR THE MID-WEEK. && .NEAR TERM /THROUGH SUNDAY/... THE LATEST RUC 500 MB ANALYSIS INDICATES A WEAKENING 500MB SHORT WAVE TROUGH ACROSS SOUTHEASTERN OHIO. BEST DEEP LAYER MOISTURE IS ASSOCIATED WITH THIS FEATURE...MOVING ACROSS NORTH-CENTRAL WV...WITH DRY AIR ALOFT ACROSS AREAS NORTH OF PITTSBURGH. AT THE SURFACE...A 1012 MB LOW IS LOCATED ACROSS JUST NORTH OF LAKE ERIE WITH A WARM FRONT EXTENDING EASTWARD ACROSS THE EASTERN GREAT LAKES. WITH THE WARM FRONT HAVING LIFTED NORTH OF THE AREA...A MOIST SOUTHWESTERLY FLOW IS IN PLACE. DEW POINTS IN THE TO LOWER 70S HAVE ADVECTED NORTHEASTWARD INTO THE AREA. AHEAD OF THE SHORT WAVE...A CLUSTER OF SHOWERS AND THUNDERSTORMS ARE MOVING ACROSS SOUTHERN WEST VIRGINIA. MORE ISOLATED CONVECTION IS DEVELOPING LOCALLY. THIS EVENING AND TONIGHT...THE MID-LEVEL SHORT WAVE CROSSING SOUTH OF THE AREA WILL CONTINUE TO TRACK FURTHER SOUTHWARD. SCATTERED CONVECTION WILL CONTINUE ACROSS THE AREA THROUGH THIS PERIOD. CLOUD COVERAGE WILL CONTINUE TO LIMIT INSTABILITY AND STRENGTHENING OF STORMS DESPITE THE MOIST ENVIRONMENT. CONVECTION WILL CONTINUE TONIGHT...BECOMING MORE ISOLATED OVERNIGHT. WITH THE AREA NEAR SATURATED AND TDS NEAR 70...IT WILL BE A HUMID AND UNSEASONABLY WARM NIGHT WITH LOWS IN THE LOWER 70S. SUNDAY...WITH THE FRONTAL BOUNDARY REMAINING NORTH OF THE AREA...ANOTHER HUMID DAY CAN BE EXPECTED WITH AFTERNOON CONVECTION DEVELOPING ONCE AGAIN. WITH THE LACK OF A FORCING MECHANISM AND WEAK SHEAR ALOFT...CONVECTION SHOULD BE MORE DIURNALLY DRIVEN. WEAK TO MODERATE INSTABILITY MAY ALLOW FOR A FEW STORMS TO BECOME STRONG. WEAK WINDS ALOFT AND FCST PWAT VALUES INDICATE THE BEST CHANCE FOR LOCALLY HEAVY RAINFALL WITH STORMS WILL BE ACROSS EASTERN OHIO AND NORTH CENTRAL WV. WITH TODAYS TEMPS TRENDING WARMER THAN GUIDANCE... AND FCST NAM/GFS BLEND OF 850 TEMPS OF 16-18C...FORECAST IS CLOSER TO THE WARMER MAV GUIDANCE WITH HIGHS IN THE MID 80S ACROSS MUCH OF THE AREA. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/... WITH THE FRONTAL BOUNDARY REMAINING NORTH OF THE AREA INTO MONDAY...AN UNSETTLED WEATHER PATTERN WILL CONTINUE WITH CONVECTION TRIGGERING AGAIN IN AFTERNOON HEATING MONDAY AFTERNOON. INSTABILITY SHOULD BE LIMITED AGAIN...WITH CHANCE POPS FORECAST DURING THE DAYTIME...DIMINISHING AS THE BOUNDARY BEGINS TO DROP SOUTH OF PITTSBURGH MONDAY NIGHT. SUNDAY NIGHT WILL BE ANOTHER WARM AND HUMID NIGHT WITH LOWS RANGING FROM THE MID 60S ALONG THE INTERSTATE 80 CORRIDOR TO NEAR 70 SOUTH OF INTERSTATE 70. HIGHS ON MONDAY WILL BE A FEW DEGREES ABOVE NORMAL. WITH THE BOUNDARY DROPPING SOUTHWARD...COOLER TDS AND DIMINISHED CLOUD COVERAGE OVERNIGHT SHOULD ALLOW FOR SOME RADIATIONAL COOLING TO KICK BACK IN FOR MONDAY NIGHT. FORECAST LOWS RANGE FROM THE MID 50S ACROSS THE INTERSTATE 80 CORRIDOR TO THE LOWER 60S ACROSS NORTH CENTRAL WV. TUESDAY...HIGH PRESSURE WILL BUILD IN FROM THE NORTH WITH THE FRONTAL BOUNDARY FINALLY DROPPING SOUTH OF THE AREA. THIS WILL ALLOW FOR A DEEP LAYER OF DRY AIR TO BUILD IN BRIEFLY ON TUESDAY. HIGHS WILL BE NEAR NORMAL VALUES ACROSS THE AREA. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... WEAK SHORT WAVES IN THE FLAT RIDGE WILL BRING A CHANCE OF SHOWERS FOR TUESDAY NIGHT INTO WEDNESDAY NIGHT. HIGH PRESSURE WILL BRING DRIER WEATHER FOR THURSDAY THROUGH FRIDAY NIGHT. A WEAK COLD FRONT MAY BRING A CHANCE OF SHOWERS FOR LATE SATURDAY. EXPECTING NEAR SEASONAL TEMPERATURES FOR THE PERIOD. && .AVIATION /01Z SUNDAY THROUGH THURSDAY/... GENERALLY MVFR CONDITIONS ARE EXPECTED OVERNIGHT AS LOW PRESSURE MOVES EAST ACROSS THE EASTERN GREAT LAKES. WHILE SOME SCATTERED CONVECTION IS POSSIBLE OVERNIGHT...COVERAGE DOES NOT LOOK TO WARRANT TAF MENTION AT THIS POINT. AS THE LOW MOVES EAST...THE COMBINATION OF SURFACE TROUGHING AND INSTABILITY WILL LEAD TO MORE COVERAGE OF CONVECTION SUNDAY AFTERNOON. AS THE COLD FRONT MOVES EAST OF THE DISTRICT SUNDAY NIGHT THE RISK OF SHOWERS WILL DIMINISH...BUT A SERIES OF WEAK SHORT WAVES WILL KEEP A CHANCE OF SHOWERS FOR MONDAY AND TUESDAY WITH GENERAL VFR CONDITIONS AND A CHANCE OF RESTRICTIONS WITH SHOWERS. A WEAK SHORT WAVE MOVING ACROSS THE NORTHERN LAKES WEDNESDAY MAY BRING A CHANCE OF SHOWERS...MAINLY IN THE NORTH BUT NOT A LARGE RISK OF FLIGHT RESTRICTIONS. HIGH PRESSURE WILL BRING DRY WEATHER FOR THURSDAY. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...NONE. OH...NONE. PA...NONE. WV...NONE. &&
