The episode as NWS BGM wrote it up.
A cold front swept through the state of New York Monday evening. Ahead of this cold front was a warm and very unstable air mass. When the front moved across the region thunderstorms develop ahead and along the front. As the front moved eastward across the state, some of the thunderstorms became severe.
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 20, 9:44 PM EST, 46 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 1044 PM EDT MON JUN 20 2016 .SYNOPSIS... A cold front will move across the region tonight and spread scattered showers and thunderstorms through the area. Cooler temperatures expected Tuesday with dry weather. Another shot of rain showers Wednesday morning before widespread showers and isolated storms Thursday. Quiet weather expected this weekend. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... 1040 pm update... Convection is now filling in between the severe complexes in far northern NY, and western NY. Though surface based cape is limited, mixed layer CAPE is around 1500 J/kg. Severe Thunderstorm Watch continues for the Finger Lakes through Mohawk Valley until midnight. It may become necessary to extend in time and area /southeast of current watch/. Forecast adjusted accordingly as confidence continues to increase. That said, instability will drop off quickly as the front moves southeast so at some point the storms will also lessen in coverage and intensity. By the time it reaches Northeast PA-Sullivan Co. NY, shear and especially instability will be lower. For now though significant shear remains throughout the column, favoring damaging winds within the strongest cells, and a secondary threat for large hail. Column overall is pretty warm which may limit hail size. 820 pm update... Severe Thunderstorm Watch has been issued for our northern Finger Lakes zones through Syracuse and Mohawk Valley. Environment remains favorable for severe thunderstorms in those locations, where convection manages to occur. Cold pools of upstream convection may provide additional focus for new convection the next few hours. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/... 400 pm update... Conditions behind the front will dry out and stabilize as a drier air mass drops in from the north. The synoptic scale flow will remain cyclonic through Wednesday and an embedded s/w will move across nrn NY late Tue and early Wed with a few light rain showers along and north of the Mohawk valley. Heights will rise aloft and a weak area high pressure builds in from the west late Wednesday ahead of the next system expected to move in from the w/sw on Thursday. There are still quite a few differences in the timing and track of this surface low...which will be critical in determining the potential for thunder and the possibility of heavy rainfall. The latest NAM is the furthest north across central NY...and the GEM is the further south through OH/WV/DE...with the GFS and ECMWF in between. Will continue with a middle of the road track through PA...placing most of the heavy precip on the nrn side of the low across srn NY and nrn PA. Rainfall amts will be challenging as well...may see up to a half to 1 inch in some locations. Temperatures will remain pleasant and steady behind the front with highs in the 70s and lows in the 50s. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... 2 PM Update... Warm dry airmass getting warmer and more humid with convection to end period. Temperatures near normal becoming above normal. Highs around 80 warming into the 80s, and lows in the 50s warming into the 60s. At upper levels on the back side of an upper level trof centered in extreme se Canada. At the surface a large area of surface high pressure with dry weather. Over the weekend a ridge builds as the surface high moves off the East coast. Increasing heat and humidity ahead of a weakening cold front. UL heights fall little through Monday but surface convergence should cause convection given airmass. Little change to previous forecast. && .AVIATION /03Z TUESDAY THROUGH SATURDAY/... Cold front will drop through 03Z NW to 07Z SE with veering wind shift and gusty showers-thunder. Confidence in thunderstorms at specific TAF sites high for KSYR-KRME-KITH 03Z-05Z. Watch for amendments for other terminals further south; storms will have a tendency to weaken. Behind the front, 5-7 kft agl deck of clouds will gradually clear, leaving VFR conditions for the day on Tuesday. Only expecting some high thin clouds around 25 kft agl, except for a few cumulus towards KAVP. SW winds 8-12 knots pre- frontal this evening, becoming WNW behind the front overnight through Tuesday. OUTLOOK... Tue Night to Sat...VFR. Maybe some MVFR conditions for AVP Thursday in light rain. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && SYNOPSIS...BJT/MDP NEAR TERM...BJT/MDP SHORT TERM...BJT LONG TERM...TAC AVIATION...MDP
