AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 208 AM EDT SAT MAY 8 2010 .SYNOPSIS... A DEVELOPING STORM WILL MOVE ACROSS THE LOWER GREAT LAKES TONIGHT...DRAGGING A STRONG COLD FRONT ACROSS THE REGION SATURDAY MORNING. GUSTY WINDS AND STRONG TO SEVERE THUNDERSTORMS WILL BE POSSIBLE OVERNIGHT. WINDY CONDITIONS AND MUCH COLDER TEMPERATURES WILL FOLLOW FOR THE REMAINDER OF WEEKEND. THERE WILL BE A CHANCE FOR SNOW SHOWERS ACROSS THE NORTHERN MOUNTAINS SATURDAY NIGHT. TEMPERATURES WILL SLOWLY MODERATE BY MID WEEK...AS HIGH PRESSURE BUILDS OFF THE EAST COAST. SOME SHOWERS COULD OCCUR AGAIN BY MID WEEK...AS ANOTHER COLD FRONT NEARS THE AREA. && .NEAR TERM /UNTIL 6 AM THIS MORNING/... REGIONAL RADAR ATTM SHOWING LINE OF STRONG TO SVR TSRA HAVE DEVELOPED ALONG NOSE OF POTENT LL JET OVR NW OHIO. LINEAR EXTRAPOLATION PUTS THIS LINE OF CONVECTION INTO THE NW MTNS ARND 05Z. SHORT RANGE MDL DATA CONTINUE TO TARGET NW PA FOR THE HIGHEST RISK OF SVR WX IN THE 05Z-09Z TIME FRAME. BEST LG SCALE FORCING SHOULD LIFT NORTH OF THE AREA LATE TONIGHT. THIS COMBINED WITH FROPA ARRIVING DURING DIURNAL MINIMUM WILL RESULT IN A SOME WEAKENING OF CONVECTION LATE TONIGHT ACROSS CENTRAL PA. HOWEVER...SIG LG SCALE FORCING AND DESTABILIZATION ALONG LL JET AXIS SHOULD SUSTAIN SCT TO LIKELY POPS INTO THE SUSQ VALLEY. SHORT RANGE MDL DATA INDICATING 1KM WINDS ARND 50KTS COINCIDENT WITH FROPA...SO SIMILAR WIND GUSTS COULD POTENTIALLY MIX TO GROUND LVL WITH STRONGER CONVECTION. && .SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/... FOCUS SHIFTS TO A SYNOPTIC HIGH WIND EVENT SATURDAY...AS COLD FRONT PUSHES EAST OF THE AREA EARLY IN THE DAY. LATEST BUFKIT SOUNDING DATA SUPPORTS GUSTS TO AT LEAST 40KTS OVR THE ENTIRE AREA BY AFTN...WITH GUSTS CLOSE TO 50KTS POSSIBLE OVR THE NW MTNS. HAVE THUS EXPANDED THE WIND ADVISORY TO COVER THE ENTIRE CWA. COLDER AIR POURS IN BEHIND THE FRONT AND EXPECT MOST TO REACH MAX TEMPS EARLY IN THE DAY BEFORE STEADY AND FALLING TEMPS BECOME THE RULE. DRY SLOT LIKELY TO BRING PTSUNNY SKIES DOWNWIND OF THE MTNS BY LATE AM...WHILE SKIES AVERAGE MCLDY OVR THE ALLEGHENY MTNS SAT. TEMPS GET DOWNRIGHT COLD SAT NIGHT WITH LOWS IN THE LOWER 30S IN THE HIGHER TERRAIN AND A40 IN THE LOWER SUSQ. WITH A STIFF WIND IT WILL FEEL EVEN COLDER. SHOWERS WILL BE DIMINISHING ACROSS THE HIGHER TERRAIN...BUT GOOD CHANCE THAT SOME WET SNOW WILL MIX IN WITH THE RAIN SHOWERS IN THESE AREAS AS GFS AND NAM BOTH DROP 850MB TEMPS TO AROUND -7C. A LIGHT COATING OF SNOW APPEARS QUITE POSSIBLE ACROSS THE HIGH TERRAIN OF THE NW. CHILLY/BREEZY WEATHER CONTINUES SUNDAY. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... THE LONG RANGE STARTS OFF UNSEASONABLY COOL. 12Z GEFS 850 TEMPS HOLDING AROUND -2SD FROM SATURDAY NIGHT INTO MONDAY AM...BOTTOMING OUT SUNDAY AM AROUND -6C ACROSS THE CWA. ASIDE FROM THE BELOW- NORMAL TEMPS...THE WX SHOULD BE FAIRLY BENIGN FROM SUNDAY INTO MONDAY. A SYSTEM WILL APPROACH THE AREA MONDAY NIGHT INTO TUESDAY...BRINGING AN INCREASE IN CLOUDS AND EVENTUALLY SOME PRECIP. 12Z OPERATIONAL RUNS OF THE GFS AND ECMWF BOTH SHOW A DECENT SLUG OF MOISTURE SLIDING ACROSS THE REGION TUES INTO TUES NIGHT...AND 12Z GEFS SHOWS POPS INCREASING SIGNIFICANTLY DURING THIS TIME. THIS SYSTEM DRAGS A COLD FRONT THROUGH THE AREA WEDNESDAY. HIGH PRESSURE MAY BRIEFLY NOSE INTO THE AREA BEHIND THIS SYSTEM...ALLOWING FOR A TEMPORARY RESPITE FROM THE UNSETTLED WEATHER ON THURSDAY. HOWEVER...ANOTHER SYSTEM IS EXPECTED TO APPROACH BY THE END OF NEXT WEEK OR EARLY NEXT WEEKEND. && .AVIATION /06Z SATURDAY THROUGH WEDNESDAY/... STRONG COLD FRONT NOW SWEEPING THROUGH THE AREA...WITH A LINE OF BROKEN TSRA EXTENDING FROM MANSFIELD TO RENOVO AND CLEARFIELD. LOCALIZED MVFR/IFR CONDITIONS EXIST WITHIN THE LINE...WITH LOCALIZED WIND GUSTS OF 40 TO 50 MPH POSSIBLE WITH FROPA. THIS FEATURE WILL SWEEP THROUGH ALL TAF LOCATIONS BY 12Z FROM WEST TO EAST OVERNIGHT. BEHIND THE FRONT...STRONG WINDS WILL DEVELOP FROM THE WEST IN ASSOCIATION WITH DEEPENING LOW PRESSURE NORTH OF THE REGION. NUMEROUS SHRA IN WESTERN AND NORTHERN AREAS TODAY...WITH MORE SCATTERED TO ISOLATED SHOWERS IN THE EAST AND SOUTH. GENERALLY...VFR CONDITIONS EXPECTED...BUT MAY SEE SOME MVFR CONDITIONS (MAINLY CIGS) IN PRECIPITATION. SCATTERED SHOWER ACTIVITY WILL LINGER INTO TONIGHT...WITH RAIN SHOWERS TRANSITIONING TO SNOW SHOWERS AS COLDER TEMPERATURE BUILD OVER THE REGION. OUTLOOK...SUN...STILL WINDY WITH SCT SHRA IN THE WESTERN AND CENTRAL AREAS. MON...NO SIG WX EXPECTED. TUE AND WED...RAIN/TSRA POSSIBLE. && .FIRE WEATHER... RECENT RAINS AND FOLIAGE GREEN UP HAVE DIMINISHED THE OVERALL FIRE DANGER TO LOW OVER MOST OF THE AREA SO NO HEADLINES PLANNED AT THIS POINT. HOWEVER...ABNORMALLY STRONG WINDS THIS WEEKEND ARE OF CONCERN. LATER SHIFTS CAN MONITOR THE SITUATION. && .CTP WATCHES/WARNINGS/ADVISORIES...
