Area forecast discussion, May 24, 8:40 AM EST, 4 hours 16 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PITTSBURGH PA 940 AM EDT SUN MAY 24 2009 .SYNOPSIS... A WEAK FRONT WILL CONTINUE TO MEANDER OVER THE UPPER OHIO VALLEY REGION FOR THE NEXT COUPLE OF DAYS PROVIDING FOCUS FOR SCATTERED SHOWERS AND THUNDERSTORMS. && .NEAR TERM /THROUGH TONIGHT/... NORTHEN STREAM SHORTWAVE WILL CROSS QUEBEC TODAY AND PROVIDE SUPPORT FOR THUNDERSTORMS FOCUSED VIA WEAK COLD FRONT ANALYZED FROM NEAR BRADFORD TO A LITTLE NORTH OF ZANESVILLE THIS MORNING. AFTERNOON HEATING AND DEWPOINTS ON EITHER SIDE OF 60F WILL PROVIDE LIMITED INSTABILITY, AND THAT FACTOR COMBINED WITH RATHER WEAK SHEAR AND MID LEVEL WIND, SHOULD INHIBIT SEVERE POTENTIAL. TEMPERATURES WILL REMAIN ABOVE NORMAL WITH MARGINALLY MOIST SURFACE DEWPOINTS CONTINUING THE SOMEWHAT HUMID CONDITIONS. && .SHORT TERM /MONDAY THROUGH MONDAY NIGHT/... WITH LOW PRESSURE DIGGING OVER THE LOWER MISSISSIPPI VALLEY, TODAYS CANADIAN DISTURBANCE WILL NOT PULL THE FRONT VERY FAR TO THE SOUTH...POSSIBLY ACROSS WEST VIRGINIA AND SOUTHERN OHIO. SO, PRECIPITATION MENTION WILL REMAIN IN THE FORECAST FOR COUNTIES ROUGHLY FROM PITTSBURGH ON SOUTH. POP NUMBERS IN THE CHANCE CATEGORY SHOULD SUFFICE FOR NOW AS THAT AREA WILL ALSO BE UNDER THE INFLUENCE OF BUILDING RIDGE ON THE VAN OF THE AFORE-MENTIONED LOW. && .LONG TERM /TUESDAY THROUGH SATURDAY/... WARM AND HUMID CONDITIONS WILL RETURN AREAWIDE BY MID WEEK AS MOISTURE DEPTH/SUPPLY INCREASES IN ADVANCE OF PLAINS-STATES LOW PRESSURE. HOWEVER, EASTERN CONUS RIDGE WITH WARM MID LEVEL TEMPERATURES WILL LIMIT EXTENT AND POWER OF THUNDERSTORMS. SHOWERS WILL REMAIN IN THE FORECAST, BUT WILL ADJUST BETTER POP NUMBERS TO BETTER ALIGN WITH EXPECTED MID-WEEK BOUNDARY POSITIONING. FOR LATE WEEK, FORECAST WILL BE OF APPROACH AND PASSAGE OF NEXT COLD FRONT ACCOMPANIED BY MORE SHOWERS AND STORMS FOLLOWED BY A DRY WEEKEND UNDER HIGH PRESSURE. && .AVIATION /13Z SUNDAY THROUGH THURSDAY/... WEAK FRONTAL BOUNDARY STRETCHED ACROSS THE REGION WILL BE THE FOCUS FOR WIDELY SCATTERED THUNDERSTORMS THROUGH MONDAY. GENERALLY VFR FLIGHT CONDITIONS WILL CONTINUE TODAY. ISOLATED THUNDERSTORMS WILL CONTINUE TO POP UP ACROSS THE SOUTH EARLY THIS MORNING, BUT COVERAGE IS TOO SPARSE TO INCLUDE IN ANY TERMINALS. EXPECT VISIBILITIES TO BE REDUCED IN AREAS OF FOG AND HAZE AT SOUTHERN TERMINALS MAINLY BETWEEN 08Z-14Z SUNDAY. EXPECT SLIGHTLY GREATER COVERAGE OF THUNDERSTORMS SUNDAY AFTERNOON AS ADDITIONAL LOW LEVEL MOISTURE SHIFTS NORTHWARD AND BOUNDARY DIPS TO THE SOUTH. OVERALL VFR CONDITIONS STILL EXPECTED. MAINLY VFR CONDITIONS EXPECTED TO CONTINUE MONDAY WITH THE RISK FOR THUNDERSTORMS SOUTH OF KPIT. FOR TUESDAY NIGHT THROUGH THURSDAY THERE IS STILL A CHANCE FOR SHOWERS AND THUNDERSTORMS AND POSSIBLE RESTRICTIONS AS GFS ENSEMBLE SHOWS A LOW PRESSURE AREA MOVING FROM THE LOWER OHIO RIVER VALLEY TO THE MID ATLANTIC COAST. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...NONE. OH...NONE. PA...NONE. WV...NONE. && 15
