NWS Binghamton, NY wrote its last area forecast discussion before the first event at Apr 18, 10:15 AM EST, 3 hours 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 1115 AM EDT SUN APR 18 2004 .UPDATE... WE ARE CURRENTLY CLOSELY WATCHING THE MCS MOVING EAST ACROSS FAR WESTERN NY LATE THIS MORNING. THAT SYSTEM WILL BE MOVING INTO A MORE STABLE ATMOSPHERE ACROSS CENTRAL NY EARLY THIS AFTERNOON... BUT COULD STILL HOLD TOGETHER LONG ENOUGH TO PRODUCE SOME PROBLEMS FOR OUR NORTHERN COUNTIES BETWEEN 1 AND 4 PM. WARM FRONT CURRENTLY IS LOCATED TO OUR SOUTH... WITH THE STRONG SHEAR PROFILES THAT ONE WOULD NORMALLY EXPECT NORTH OF A WARM FRONT LOCATED OVER OUR AREA. THE QUESTION TODAY WILL BE WHETHER OR NOT THE ATM CAN GET UNSTABLE ENOUGH TO SUPPORT STRONG / SEVERE CONVECTION. THE ETA IS SHOWING CAPES REACHING OVER 1000 J/KG ACROSS OUR NORTHERN CWA THIS AFTERNOON WHILE THE LATEST RUC IS MORE CONSERVATIVE...ONLY SHOWING 300 TO 500 J/KG. LARGE CANOPY OF MID AND HIGH CLOUDS WILL BE OVERSPREADING THAT AREA SOON... AND LATEST SURFACE OBS NOT INDICATING A BIG RETURN OF LOW-LEVEL MOISTURE. STILL... FEEL THAT WITH MARGINAL INSTABILITY THERE COULD STILL BE ENOUGH INSTABILITY TO SUPPORT A FEW STORMS THAT WILL APPROACH SEVERE LIMITS... AND WILL UPDATE THE FORECAST TO INCLUDE ENHANCED WORDING INCLUDING GUSTY WINDS AND HAIL FOR THE NORTHERN 1/3 OF THE CWA. WITH STRONG... TURNING SHEAR PROFILES IN PLACE ACROSS OUR AREA WE WILL HAVE TO WATCH FOR ROTATING STORMS IN ADDITION TO A BOW ECHO TODAY... ALTHOUGH FAIRLY HIGH LCL HEIGHTS AND WEAK STABILITY IN THE LOWEST LEVELS WILL NOT BE FAVORABLE FOR TORNADOES. .DISCUSSION... MAIN CHALLENGE FOR TDA WILL BE MAX TEMPS AND THE POTNL FOR (SVR?) CONVECTION. CDFNT HAS SAGGED OF THE RGN, BUT WILL RETURN AS A WMFNT LATER TDA. AT 925 MB, THA ETA/NGM SHOW A 19-20C 925 MB THERMAL RDG OVER CNTRL SRN TIER INTO FINGER LAKES BY 00Z WITH GRADIENT TO COOLER TEMPS ACRS THE WRN MOHAWK VLY/WRN CATSKILLS/ERN POCONOS THIS AFTN. THE 700 AND 500 MB VORT PROGS SHOW THE PSSG OF A WEAK S/WV THIS AFTN. THE ETA PROFILES ARE QUITE IMPRSV, SHOWING CAPES OF 1000-1500 AND LIS FROM -3 TO -6 THIS AFTN, COUPLED WITH VERY IMPRSV SHEAR PROFILES LEADING TO VALUES OF BRN, HELICITY AND EHI WHICH SUGGEST SVR POTNL - ASSUMING WE CAN GET STORMS TO DVLP. ON THE NEG SIDE, NCAPES ARE NOT IMPRSV, AND THE ETA DOES SHOW A CLOSED -18C COLD POCKET OVER CNTRL NY AT 18Z, WHICH IS NOT INDICATED BY THE NGM. HOWEVER, THE FCST LOW LVL TDS IN THE ETA PROFILE LOOK RSNBL, SPCLY SINCE TDS IN THE U50S AND L60S ARE AS CLOSE TO OUR RGN AS WRN PA AND ERN OH. THIS LOW LVL MSTR WILL WORK NEWD TDA ON FAIRLY STRONG LOW LVL SW FLOW. OUR NRN ZONES ARE OUTLOOKED WITH SLIGHT RISK THIS AFTN, AND THIS LOOKS GOOD, BUT WOULD NOT RULE OUT STRONG STORMS INTO THE SRN TIER TDA (ASSUMING THEY DVLP OF COURSE). NGM/MAV POPS ARE CHC AREA-WIDE TDA, WITH ETA INDICATING HIGH CHC OR LIKELY POPS OVER THE FINGER LAKES AND WRN MOHAWK VLY. HATE TO FLIP-FLOP BUT WILL HAVE TO RE-INTRODUCE CHC POPS FOR AFTN SHRA/TSRA ACRS ALL AREAS, WITH HIGHEST POPS ACRS THE FINGER LAKES/WRN MOHAWK VLY AND SRN TUG. WILL HOLD OFF ON ENHANCED VERBAGE, TO LET DAY CREW LOOK AT LATEST GUIDANCE, BUT WILL MENTION SVR POTNL IN THIS MRNGS HWO FOR NRN ZONES. AS FOR TEMPS, I LIKE THE 80F FOR ELM THIS AFTN, WHICH IS SUPPORTED BY THE FCST 925MB TEMPS, BUT THINK THE 80F FOR SYR IS TOO WARM SINCE THE WMFNT WONT BE PASSING THERE UNTIL LATE TDA. WILL LEAN TWDS CONTINUITY FOR TDAS MAXES, WITH LOWER READINGS FAR NRN ZONES, WRN CATSKILLS AND ERN POCONOS WHERE MDLS INDICATE SELY FLOW PERSISTING TDA. ETA SHOWS MUCH DRIER AIR WORKING IN AT 850 MB TNGT ON A GOOD SW BREEZE. ANY LINGERING CONVECTION IN THE EVNG SHUD GIVE WAY TO MAINLY CLEAR OR PC SKIES. LTL IF ANY CHG TO LATTER PDS. NXT CDFNT WILL PASS ON MONDAY WITH ANOTHER CHC FOR CONVECTION, AND THIS IS REFLECTED IN THE CRNT GRIDS/FCST. BRADY. && .EXTENDED (MON NITE-SAT) SOME SIG CHANGES MADE TO MIDDLE-END PART OF THIS FCST PERIOD PER TREND OF OPERATIONAL AND ENSEMBLE GFS MODELS MOVING SERIES OF LOW PRES AREAS FASTER WITH EACH RUN. HPC 3-7 DAY PROGS A GOOD GUIDE... AND BRING COLD FRONT AND SOME SHOWERS CROSS THE AREA MON NITE. THIS FROPA BREAKS THE ABOVE NORMAL WARMTH IN PLACE ...AND IS FOLLOWED BY DRY AND MORE SEASONABLE WX TUES. RAIN CHANCES PREVIOUSLY EXPECTED THURS...HAVE BEEN BUMPED UP TO WEDS AS PROGS SHOW LOW MOVING FROM UPR MIDWEST EARLY WEDS TO GULF OF ST. LAWRENCE EARLY THURS...WITH A ONE-TWO PUNCH FROM A WARM FRONT THEN COLD FRONT MOVING THROUGH CNY/NEPA WEDS-WEDS NITE. MOST OF THURS THRU FRI NOW DRY AND COOLER POST FROPA...WITH NEXT IN SERIES OF LOWS TO MOVE IN FOR SAT AND BEYOND. && .AVIATION... MID CLDS WORKG ACRS CWA ATTM...SHUD SCT OUT SOON. SEE SOME MVFR AND EVEN IFR FOG (ELM) DVLPG AFTER 08-09Z AS COOLER BNDRY LYR SNEAKS IN UNDER INCREASING LL MOISTURE FROM THE SW JUST ABV BNDRY LYR. THIS SHUD ALLOW FOR SOME LIGHT FOG MOST TAFS...WITH SOME THICKER FOG PSBL IN THE COOLER VALLEYS LIKE ELM. && .BGM WATCHES/WARNINGS/ADVISORIES... NY...NONE. PA...NONE.
