The episode as NWS BGM wrote it up.
An upper level storm system moved east across the Ohio Valley region Monday and the attendant surface low propagated northeast in central Quebec. The mentioned surface low forced a cold front across the region as it lifted north. A line of organized thunderstorms developed along the advancing cold front by Monday afternoon. Strong to severe thunderstorms quickly developed and produced wind damage as the front advanced east through the early evening.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Binghamton, NY wrote its last area forecast discussion before the first event at Jun 8, 10:10 AM EST, 1 hour 35 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BINGHAMTON NY 1110 AM EDT MON JUN 8 2015 .SYNOPSIS... SHOWERS AND THUNDERSTORMS WILL BE PREVALENT THROUGH TONIGHT...AHEAD OF A SLOW MOVING COLD FRONT. A FEW STRONG TO SEVERE STORMS ARE POSSIBLE THIS AFTERNOON AND EVENING...WITH LOCALLY GUSTY WINDS AND HEAVY RAINFALL. SHOWERS WILL BECOME MORE WIDELY SCATTERED ON TUESDAY...WITH DRIER WEATHER EXPECTED ON WEDNESDAY. && .NEAR TERM /THROUGH TONIGHT/... 1055 AM UPDATE...TRICKY SCENARIO UNFOLDING...WE HAVE AN ENVIRONMENT WITH VERY STRONG SHEAR (FAVORABLE FOR SEVERE WEATHER) BUT STILL A LOT OF CLOUD COVER WHICH MAY ACT TO LIMIT HOW UNSTABLE WE GET. THAT SAID, SEE AT LEAST SOME BREAKS OCCURRING SO STILL A POTENTIAL THAT STORMS INITIATED BY SHORTWAVE/HEATING COULD BECOME SEVERE, POSSIBLY EVEN SUPERCELLULAR, IF WE GET ENOUGH HEATING. FOR THIS REASON BEEFED UP ENHANCED WORDING IN GRIDS TO MORE EXPLICITLY MENTION SEVERE THUNDERSTORM THREAT FOR THIS AFTERNOON. DAMAGING WINDS STILL LOOK TO BE THE BIGGEST THREAT BUT HEAVY RAIN, HAIL, EVEN TORNADIC DEVELOPMENT CAN'T BE RULED OUT GIVEN THE VERY STRONG DEEP LAYER SHEAR. THINKING IS INITIAL THREAT WILL BE HIGHEST AROUND 18Z OVER THE FINGER LAKES REGION AS INITIAL SHORTWAVE MOVES IN FROM WESTERN NY WITH HIGHEST SEVERE WEATHER THREAT MIGRATING SOUTH BY LATER THIS AFTERNOON INTO THIS EVENING. 430 AM UPDATE... AN ACTIVE PD MAY BE ON TAP FOR CNY/NE PA. A BATCH OF SHWRS AND ISOLD/ELEVATED THUNDER IS PUSHING THROUGH THE FA THIS MRNG...ASSOCD WITH STG WAA FORCING AND THE PASSAGE OF A WEAK S/WV AT MID-LVLS OF THE ATMOSPHERE. ACRS OUR NRN ZNS (THE NRN FINGER LAKES...MOHAWK VLY...AND SRN TUG HILL RGNS)...SHWRS AND EMBEDDED THUNDER SHOULD REMAIN FAIRLY NUMEROUS THROUGH THE MRNG HRS...CLOSER TO THE ACTUAL SFC WARM FRNT AND RIBBON OF ISEN LIFT. MEANWHILE...ACRS THE SRN TIER AND NE PA...SHWRS WILL BE MORE SCTD IN NATURE...WITH A FEW BREAKS OF SUNSHINE EVEN PSBL INTO EARLY AFTN...SPCLY OVER PTNS OF NE PA AND OUR WRN CATSKILL ZNS. THE MOST INTERESTING PD IS THIS AFTN AND EVE...AS THE COMBO OF DAYTIME HEATING AND HGT FALLS ALOFT...AT THE LEADING EDGE OF AN UPR-LVL TROUGH...DESTABILIZES THE ATMOSPHERE. CURRENTLY...WE PROJECT THE GREATEST INSTABILITY TO RESIDE OVER NY'S SRN TIER AND NE PA...WHERE ML CAPES COULD APPROACH 1000-1500 J/KG. GIVEN MORE PERSISTENT CLDS/PCPN...OUR NRN/FAR WRN ZNS SHOULD REMAIN MORE STABLE. WE FEEL THE NAM AND RGNL GEM HAVE A MUCH BETTER HANDLE ON THE EVOLVING CAPE PROFILES...WITH THE GFS/RAP/HRRR MODELS TOO LOW...AS HAS BEEN THE CASE MANY TIMES THE LAST SVRL WEEKS. ALSO...WIND FIELDS ARE FAIRLY IMPRESSIVE...WITH GOOD NWP AGREEMENT ON 0-1/0-3/0-6 KM SHEARS OF 20/35/40 KT RESPECTIVELY...BY LATE AFTN/EARLY EVE. SUCH AN ENVIRONMENT...IF REALIZED...COULD SUPPORT A FEW ROTATING SUPERCELLS...WITH SPC SSEO GRAPHICS INDICATING THIS POTENTIAL. OUR IN-HOUSE SVR WX ANALOG SYSTEM IS ALSO SHOWING THE PSBLTY OF ISOLD TORNADIC SUPERCELLS. ALL OF THIS WILL HAVE TO BE CLOSELY WATCHED LTR TDY...SPCLY AFTER 2-3 PM...AND ALSO NEAR AND E OF I-81...AS WELL AS NEAR AND S OF I-88. BESIDES THE SVR WX POTENTIAL...ATMOSPHERIC INGREDIENTS ALSO SUPPORT HEAVY CONVECTIVE RAINFALL...SPCLY THIS EVE AFTER 6-8 PM. PROGGED PWAT VALUES (1.75-2") ARE CLOSE TO 200% OF NORMAL...WITH DEEP WCD'S (10-12 K FT)...AND FAIRLY SMALL MBE VECTORS (PSBL TRAINING/REPEAT CELLS). SLUGGISH APPROACH OF THE MAIN SFC FRNT (DEEP-LYRD FLOW NEARLY PARALLEL TO IT) AND CONTINUED ENTRANCE RGN UPR JET DYNAMICS OVERNIGHT...COULD KEEP THE THREAT OF LOCALLY HVY RAIN GOING THROUGH MUCH OF THE EVE (NEAR OR EVEN PAST MIDNIGHT)...UNTIL MORE ROBUST CONVECTIVE ELEMENTS/RAIN RATES START TO WEAKEN WITH SLOW DIURNAL STABILIZATION. IF A SPECIFIC TARGET AREA BCMS MORE CONCRETE LTR TDY OR THIS EVE...THEN A FF WATCH WOULD BE CONSIDERED. UNTIL THEN...WE'LL SIMPLY CONTINUE TO MENTION DUAL SVR WX/HVY RAIN THREAT IN THE HWO. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... 330 AM UPDATE... WITH AN UPPER LEVEL TROF AXIS STILL TO OUR WEST, AND OUR AREA IN THE FAVORABLE REGION FOR LIFT AHEAD OF THE TROF, STEADY RAIN WILL CONTINUE THROUGH A GOOD CHUNK OF THE DAY. WHILE PWATS WHICH WILL BE AROUND 1.5 INCHES EARLY SLOWLY DROP OFF, ANY ADDITIONAL MODERATE PERIODS OF RAIN THROUGH MIDDAY MAY STILL CAUSE PROBLEMS WITH FLOODING, ESPECIALLY IN AREAS THAT SEE HEAVY RAIN TODAY/TONIGHT. RAIN WILL GRADUALLY LESSEN IN INTENSITY BY AFTERNOON BUT WE DO NOT EXPECT ANY PERIOD OF DRYING UNTIL TUESDAY NIGHT WHEN THE TROF AXIS MOVES TO OUR EAST BY 06Z WED. WEAK SURFACE RIDGING WILL BRING DRIER WEATHER FOR THE FIRST HALF OF WEDNESDAY. 0Z MODEL GUIDANCE IS A GOOD 12 HOURS FASTER WITH THE NEXT SYSTEM WEDNESDAY EVENING. THE CANADIAN/GFS/NAM ALL BRING IN PRECIP BY 0Z THURSDAY FROM STEUBEN COUNTY UP THROUGH THE NORTHERN FINGER LAKES. INCREASED POPS WEDNESDAY AFTER 22Z TO ACCOUNT FOR THIS. && .LONG TERM /THURSDAY THROUGH SUNDAY/... 330 AM UPDATE... WITH THE MAIN FOCUS ON SEVERE AND FLOOD POTENTIAL TODAY/TONIGHT, JUST TOOK A QUICK LOOK AT THE EXTENDED. OVERALL WE ARE IN GOOD SHAPE. AFTER A WEAKER SYSTEM THURSDAY EXITS, WE SHOULD SEE SOME DRY WEATHER THURSDAY NIGHT INTO THE FIRST PART OF FRIDAY. THE NEXT SYSTEM BRINGS UNSETTLED WEATHER BACK TO THE REGION FRIDAY AFTERNOON AND NIGHT. MOST MODEL CONSENSUS IS THIS LINGERS INTO PART OF SATURDAY BUT AS OF NOW, DRIER WEATHER COULD ARRIVE AS EARLY AS SATURDAY EVENING. THE PREVIOUS AFD IS BELOW... 130 PM UPDATE... FOLLOWING WPC GUIDANCE. MODEL DIFFERENCES WITH EURO NOT IN. GFS FASTER WITH THE FIRST SYSTEM LATE WED TO THU. A WEAK UPPER LEVEL TROF MOVES ACROSS SE CANADA. A COLD FRONT GOES SE THROUGH THE CWA THURSDAY. THE FRONT STALLS IN PA FRIDAY. AFTER THAT MODELS DIFFER ON WHEN AND IF THE FRONT LIFTS BACK NE. UNSETTLED WITH TEMPERATURES AT OR ABOVE NORMAL. && .AVIATION /15Z MONDAY THROUGH FRIDAY/... 12Z MON UPDATE... MVFR RESTRICTIONS CAN BE EXPECTED EARLY THIS MRNG AT KELM/KITH/KBGM...WITH LWR CLDS IN THE VICINITY. AFTER 14-15Z...WE SHOULD SEE MAINLY UNRESTRICTED CONDS INTO EARLY AFTN. THEREAFTER...FROM MID-AFTN INTO THIS EVE...SHWRS/TSTMS WILL BECOME MORE FREQUENT...HENCE RENEWED DEVELOPMENT OF RESTRICTED CONDS. WE INSERTED A TEMPO GROUP FOR TSRA AT KELM/KITH/KBGM/KAVP...WITH JUST SHWRS FOR NOW AT KSYR/KRME. RESTRICTIONS WILL CONTINUE OVERNIGHT...WITH WIDESPREAD SHWRS/ISOLD EVE THUNDER. GUSTY S TO SW WINDS THIS MRNG (LOCALLY 25-30 KT...SPCLY KSYR)...WILL DECREASE A BIT BY LTR THIS AFTN AND TNT. .OUTLOOK... TUE...RESTRICTIONS POSSIBLE IN SCATTERED SHOWERS AND THUNDERSTORMS.
