AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE BINGHAMTON NY 940 AM EDT SUN AUG 29 2004 .SHORT TERM... LOTS OF SUNSHINE ACRS THE FCST AREA WITH A FEW -SHRA ACRS THE WRN FINGER LAKES. SFC ANYLS SHOWS FNLY BNDRY ACRS LAKES ERIE AND ONTARIO INTO FAR NRN NY, WITH A WEAK LOW SITUATED ALONG THE FNT OVER LAKE ERIE. MODIFIED BUF/ALY/PIT SNDGS USING A MEAN LOW LVL PARCEL AND SFC T/TD OF 82/70 GIVES CAPES FROM 1300-2000 J/KG AND LIS FROM -3 TO -5. WET BULB ZERO VERY HIGH (ABV 13K FT) SO THERE APPEARS TO BE A MINIMAL THREAT FOR HAILERS. WIND FIELDS ARE ABOUT 10-15 KTS STRONGER THAN YDA, AND 0-1,0-3 AND 0-6 BULK SHEAR PARAMS INDICATE POTNL FOR SOME ORGANIZATION ACRS UPSTATE NY, PRIMARILY FROM THE FINGER LAKES INTO THE WRN MOHAWK VLY. ALSO NOTE THAT BRNS ARE IN THE SUPERCELL RNG ACRS NRN ZONES THIS AFTN. ACRS NE PA THE BULK SHEAR PARAMS ARE WEAKER. FORTUNATELY, THERE IS NO SIG CAP IN THE 12Z PROFILES. XPCT STORMS TO EXHIBIT THE BEST ORGANIAATION ACRS UPSTATE NY, SPCLY NRN ZONES. ACRS NE PA, A LESSER THREAT BUT STILL POTNL FOR SOME ISOLD TO WDLY SCT PUSLE-TYPE SVR. THERE WILL ALSO BE A THREAT FOR FOR HEAVY RAINERS, AS MBE VECTORS SHOW POTNL FOR SOME TRAINING TDA, THE FLOW IS PRIMARILY UNIDIRECTIONAL ALOFT AND PARALLEL TO THE FNTL BNDRY, WARM CLD DEPTHS ARE WELL ABOVE 10K FT, AND PRECIPITABLE WATER VALUES ARE VERY HIGH (1.75 TO 2 INCHES). QUESTION IS WHERE WILL THE STORMS INITIATE? 06Z MESO ETA SUGGESTS THAT CONVECTION COULD FIRE UP ALONG A WEAK PRE-FNTL TROF FROM CNTRL PA INTO THE SUSQ RGN OF NY THIS AFTN. 12Z SFC ANYLS DOES SHOW A WEAKNESS HERE. OTHER STORMS LIKELY TO FIRE UP JUST EAST OF THE FNT ACRS WRN NY, THEN PROPAGATE NEWD INTO CNTRL NY. ACRS NE PA, PULSE-TYPE CONVECTION MAY TEND TO INITIATE OVER THE HIGHER TERRAIN. WE WILL ISSUE AN SVR WX OUTLOOK FOR THE ENTIRE AREA, WITH EMPHASIS ON UPSTATE NY/GUSTY WINDS AND +RA. OTRW NO SIG CHGS TO THE FCST AT THIS POINT. .PREV DISCUSSION... SHORT TERM (MONDAY-TUESDAY NIGHT)... STATIONARY FRONT REMAINS DRAPED JUST NW OF CWA. WAVES CONTINUE TO ROTATE ALONG AND OVER THE FRONT ENHANCING CONVECTION IN THE WARM MOIST AIR. TROF DIGS SOUTH INTO IL AND IN TODAY EDGING THE STATIONARY FRONT EASTWARD. JET ENERGY FINALLY MAKES ITS WAY INTO NY/PA. GIVEN STRENGTHENING WIND FIELD AND MOIST UNSTABLE AIR IN PLACE...APPEARS WE NEED TO CONSIDER SEVERE CONVECTION THIS AFTERNOON AND EVENING. STILL WARM AT ALL LEVELS SO CAPES NOT LIKELY TO EXCEED 600-1000 J/KG. HOWEVER WIND FIELD COMBINED WITH SOME INSTABILITY SHOULD PRODUCE A FEW PULSE CELLS CAPABLE OF CAUSING TORRENTIAL DOWNPOURS AND ISOLATED DAMAGING WINDS. NOT MUCH OF A COOL AIR PUSH BEHIND FRONT, AND HUMID AIR IS RATHER DEEP TO THE SOUTHEAST. SO RESULT IS FRONT WILL VERY SLOWLY SLOG ITS WAY SOUTHWARD. NOW IT APPEARS IT MAY NOT EXIT THE REGION UNTIL TUESDAY MORNING...SO WE ARE KEEP SKIES MOSTLY CLOUDY AND POPS ON THE HIGH SIDE THROUGH LATE MONDAY. DJP && LONG TERM (WEDNESDAY-SUNDAY)... PCPN XPCTD TO TAPER OFF MON NGT FROM W TO E AS FNTL SYSTEM FINALLY MOVES OUT OF THE RGN. REMAINDER OF THE WEEK LOOKS DRY WITH HIGH PRES IN CONTROL. TEMPS CLOSE TO MEX VALUES. && AVIATION... ALREADY HUMID AIRMASS CONTINUES TO MOISTEN. DEW POINT DEPRESSIONS NEAR ZERO IN MOST SPOTS OVER SOGGY TERRAIN...SO WIDESPREAD MIST/FOG HAS DEVELOPED. VIS RESTRICTIONS OF 1/4 MILE OR LESS AND CIGS BELOW 100 FEET WILL OCCUR FROM TIME TO TIME ACROSS MOST SITES THROUGH 12Z. STATIONARY FRONT WILL BRING SCATTERED CONVECTION TO REGION THIS AFTERNOON AND EVENING WITH HEAVY DOWNPOURS AND GUSTY WINDS. DJP && .BGM WATCHES/WARNINGS/ADVISORIES... NY...NONE. PA...NONE. &&
