AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 949 AM EDT SAT JUL 7 2012 .SYNOPSIS... ONE MORE HOT DAY FOR NORTHEAST PENNSYLVANIA AND MUCH OF CENTRAL NEW YORK...BEFORE THE HEAT IS FINALLY BE KICKED OUT BY A COLD FRONT. AS THE FRONT SAGS SOUTHWARD THIS AFTERNOON AND EVENING...THERE WILL BE A CHANCE OF THUNDERSTORMS...SOME OF WHICH COULD CONTAIN STRONG GUSTY WINDS. A SHOWER OR THUNDERSTORM COULD LINGER INTO SUNDAY IN NORTHEAST PENNSYLVANIA AS THE FRONT EXITS. BEHIND THE FRONT...DRY WITH SEASONABLE TEMPERATURES THROUGH WEDNESDAY. && .NEAR TERM /THROUGH TONIGHT/... 930 AM UPDATE... SHOWERS ASSOCIATED WITH A COLD FRONT ARE MOVING INTO THE SYRACUSE-UTICA AREA AT THIS TIME. THUNDERSTORMS ARE BACK OVER ROCHESTER AND WILL EVENTUALLY MAKE THEIR WAY IN. INCREASED THE POP OVER THE NORTHERN FORECAST AREA TO LIKELY WITH THUNDER POSSIBLE. AREA OF SHOWERS AND STORMS WILL SAG SOUTH AND EAST WITH THE FRONT THROUGH CENTRAL NY THROUGH MID DAY WITH FOCUS MOVING INTO NE PA BY MID TO LATE AFTERNOON. SLIGHT RISK FOR SEVERE TSTMS OVER NE PA LATE THIS AFTERNOON AND EVENING. CURRENTLY FAIRLY STABLE THROUGH CENTRAL NY. SOME DESTABILIZATION OVER WESTERN NY...BETTER CAPE AND SHEAR...SO WILL HAVE TO KEEP EYE ON DEVELOPMENT OUT. FROM PREVIOUS DISCUSSION... HEAT ADVISORY REMAINS IN EFFECT FROM NOON TO 8 PM FOR SULLIVAN- LACKAWANNA- PIKE-LUZERNE COUNTIES...WHERE HEAT INDICES WILL BE AROUND 100 DEGREES. 850MB TEMPERATURES THERE WILL BE AN IMPRESSIVE 22-24 DEG C. FARTHER NORTH...INCREASING CLOUDS...FALLING HEIGHTS...AND FRONT ITSELF WILL DAMPEN AMOUNT OF HEATING TODAY. LARGE GRADIENT IN TEMPERATURES ACROSS OUR AREA...WITH HIGHS RANGING FROM MID TO UPPER 90S IN LOWER ELEVATIONS OF WYOMING VALLEY AND SOUTHERN DELAWARE VALLEY...TO LOW-MID 80S IN NY THRUWAY COUNTRY. SURFACE-BASED INSTABILITY QUICKLY DROPS SOUTH OF THE AREA TONIGHT...AS FRONT CONTINUES TO SAG SOUTH...BUT ELEVATED INSTABILITY COULD STILL YIELD AT LEAST SOME EMBEDDED THUNDER IN PORTIONS OF NORTHEAST PA MUCH OF THE NIGHT. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... 445 AM UPDATE... FRONT CONTINUES TO SLIDE SOUTH SUNDAY. LINGERING SMALL CHANCE OF SHOWERS OR A THUNDERSTORM ALSO QUICKLY SHIFTS SOUTH...YIELDING TO DRIER COOLER AIR MASS AND BUILDING CANADIAN HIGH PRESSURE. QUIET DRY PATTERN THROUGH MONDAY NIGHT...WITH FEW CLOUDS AND NEAR NORMAL TEMPERATURES THAT WILL SEEM QUITE COOL AFTER THE RECENT HEAT. DEW POINTS MAINLY IN THE 50S WILL ALSO FEEL VERY COMFORTABLE. && .LONG TERM /TUESDAY THROUGH FRIDAY/... NE US WILL CONT TO ESCAPE THE WORST OF THE HEAT...CONTD INTO THE XTNDD PD. BROAD TROF OVER THE NE QUARTER OF THE US AND ERN CANADA WILL KEEP A NW FLOW OF COOL AIR...AND THE SFC BDNRY WELL SOUTH OF THE AREA. SHRT WV DROPPING IN THE FLOW WITH A WEAK SFC REFLECTION COULD TRIGGER SOME ISLTD SHWRS AND TRWS LATE IN THE PD...BUT IN GNRL...CONDS WILL REMAIN DRY. TEMPS WILL BE VERY NEAR NRML THRU THE PD...BUT CREEPING UPWARD LATE AS THE TROF BEGINS TO FILL AND SOMEWHAT WARMER AIR BEGINS TO RETURN. && .AVIATION /14Z SATURDAY THROUGH WEDNESDAY/... MAINLY VFR CONDITIONS THIS MORNING AHEAD OF A COLD FRONT THAT WILL MOVE INTO THE AREA LATER TODAY. THERE ARE A FEW LOCALIZED SPOTS OF MVFR DUE TO SOME LIGHT FOG. THIS SHOULD NOT LAST LONG AS DAYTIME HEATING AND MIXING BEGIN THIS MORNING. AS FOR THE COLD FRONT MOVING INTO THE AREA TODAY, THE MODELS ARE STILL DIFFERING GREATLY WITH STRENGTH AND LOCATION OF ANY CONVECTION. CURRENTLY THINKING KEEP SOME VERY LIGHT SHOWERS, IF ANYTHING IN THE KSYR AND KRME TAF SITES BEGINNING AROUND 16Z TO 17Z. KITH AND KBGM WILL SEE A LITTLE STRONGER DEVELOPMENT AND AN ISOLATED THUNDERSTORM WILL BE POSSIBLE , BUT CURRENT LIKELIHOOD IS LESS THAN 30 PERCENT, SO ONLY A MENTION OF SHRA IN THE TAF FOR NOW. THE BEST CHANCE FOR SHOWERS AND THUNDERSTORMS LOOKS TO BE AT KELM AND KAVP LATER THIS AFTERNOON AND EVENING, AS THE COLD FRONT WILL HAVE THE BENEFIT OF SOME DAYTIME HEATING AND A LITTLE MORE INSTABILITY IN THE AREA. AS PREVIOUSLY THOUGH, SOME OF THE STORMS COULD BECOME STRONG TO SEVERE, ESPECIALLY FROM THE SOUTHERN TIER SOUTH, INTO NEPA. WINDS ARE LIGHT AND VARIABLE THIS MORNING. THEY WILL PICK UP OUT OF THE WEST TO WEST NORTHWEST AFTER SUNRISE AROUND 5 KTS. WITH THE FRONTAL PASSAGE TODAY, THEY WILL BECOME NW TO NORTHERLY AROUND 10 TO 15 KTS. A RETURN TO LIGHT AND VARIABLE IS EXPECTED LATE THIS EVENING. OUTLOOK... SAT NGT (AFTER 00Z)...LINGERING SHWRS/STORMS ACROSS NE PA WITH POSSIBLE MVFR CONDITIONS AT AVP THROUGH 03Z.
