The episode as NWS BGM wrote it up.
An intense cold front moved through Central New York and Northeast Pennsylvania during the late evening/overnight hours of the 14th into the 15th. This front eventually triggered a major squall line, which produced severe thunderstorms across the area. This squall line also produced an EF1 tornado in the Port Crane/Fenton/Colesville Area in Broome County. The combination of the severe thunderstorms and EF1 tornado knocked down numerous trees and damaged several structures.

NWS Binghamton, NY wrote its last area forecast discussion before the first event at Apr 14, 7:01 PM EST, 2 hours 32 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Binghamton NY 801 PM EDT Sun Apr 14 2019 .SYNOPSIS... A period of rain and scattered thunderstorms will impact the area late this evening and overnight. Some thunderstorms could be severe with damaging winds, heavy rain and small hail. Monday will be much cooler and cloudy with lingering rain showers, mixing with wet snow during the afternoon and evening. && .NEAR TERM /THROUGH MONDAY NIGHT/... 750 PM UPDATE...Severe thunderstorms just entering extreme western NY at this time. Over our area, just some widespread light to moderate showers associated with an ill defined warm front. Have adjusted the pops and weather to account for the break in the action ahead of the convection. Also adjusted the temps due to the wide variability depending pf precip and position to the fronts. 4 pm update... Minor changes mostly to the timing of a line of thunderstorms late this evening and overnight. This will be the biggest threat this period. Despite the hour of day, thunderstorms could be severe with damaging winds and maybe a tornado. This all being forced by a strong system in the Ohio Valley now moving through upstate NY late tonight. Very strong winds are pumping warm moist air into the area now. Dewpoints in the 40s will rise into the 50s. AVP already at 60. This will help with the low level instability. Cape will be between 500 and 1k. Also low level winds will be turning and increasing with height to provide bulk shear of over 50 kts. An approaching upper level jet will provide added lift. Model soundings indicate that our area will likely be in a low CAPE high shear environment this evening and tonight. Shear values are almost off the charts; with 0-6km bulk shear around 60-75 kts, 0-1km shear around 45-55 kts and 0-1km helicity up to 500 M2/S2. Effective inflow layer shear reaches 50 kts across NE PA between 00-06z tonight. The Storm Prediction Center (SPC) has a large portion of our forecast area under a Slight Risk for severe thunderstorms still. A small portion of the area along our southwest border (Bradford/Luzerne counties) is under an Enhanced Risk. WPC also has our entire forecast area under a Slight Risk for excessive rainfall. Warm frontal rain across the area now. Amounts mostly under half an inch. This will not cause any problems. Models show this moving out by 8 PM. Then wait for the next trigger late evening. Rain moves into NEPA while a line forms with the cold front towards midnight. This line progresses quickly across the area to be gone by 6 AM. Thunderstorms will have strong winds and heavy rain. With the wet ground this could cause localized flash flooding. Total rainfall of around an inch. This rain will run off and rivers will rise but not flood. River forecasts all below flood stages. This is true even in Oneida County where the bulk of the snow just melted. Temperatures fall late tonight then stay there with strong cold air advection from the northwest. Clouds will remain over NY with some showers. Colder temperatures falling through the 40s and even 30s by late in the day in CNY will give the area some snow mixing in. Some light snow accumulations possible across the higher terrain in CNY late Monday into Monday evening. The showers end around midnight. Temperatures fall mostly into the low 30s Monday night. High pressure builds into the area late Monday night into Tuesday. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... Tuesday: High pressure is expected to build eastward into our region from the Great Lakes. This may provide a temporary window of clearing. However, several ensemble members and the operational GFS are faster with a warm front approaching the area Tuesday afternoon. With that said, an isolated shower can not be ruled out Tuesday afternoon west of I-81. Highs Tuesday should warm into the 50's. Tuesday night through Wednesday night: A warm front is expected to move into the region and only slowly move throughout this period. Moisture is likely to overrun this boundary to produce clouds and some light showers on occasion. The ECMWF suite continues to be on the drier end with the operational GFS and the GEFS slowly coming down in terms of rainfall coverage and intensity. Therefore, rain chances have been lowered given the lower coverage of rainfall expected at this time. Clouds should keep lows around 40 Tuesday night with highs Wednesday a few degrees warmer than Tuesday. If we continue a drying trend in this time period, fire weather may become more of a concern if the warm front trends slower on tuesday with the moisture advection late in the day. Right now Minimum RH values look to be around 35-40% along with momentum transfer off of soundings showing the potential for some 20 mph gusts. Both of these do not reach critical values. The passage of a warm front should keep temperatures in the 40's again Wednesday night. && .LONG TERM /THURSDAY THROUGH SUNDAY/... Thursday and Thursday night: The warm frontal boundary is likely to lift north of the region allowing for a drier and warmer period ahead of the next cold front. A marine layer may keep low clouds around across the Southern Catskills during the day Thursday. This will keep that region slightly cooler with the rest of the region seeing highs in the 60's. Given the warm air advection and clouds thursday night, temperatures should only fall into the 50's. Friday through Sunday: Another very dynamic setup is likely with a strong cold front moving across our area. Plenty of warm and moist air should move into our region ahead of the front. Moisture should be lifted along the cold front for several rounds of showers. Ensembles are showing some instability riding northward ahead of the front leading to a thunderstorm threat as well. Given the likelihood of a high shear environment as well, another severe thunderstorm threat is possible. Timing of the front and northward extent of the instability are still somewhat uncertain being around 5 days out. The front looks to be slow exiting the region with more in the way of showers lingering around next weekend. Temperatures look to cool into the 50's and 60's this weekend with 40's for lows. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... Highly variable and difficult to forecast conditions this evening as a warm front with deep moisture and a southwest flow sweeps through the area. Conditions vary from IFR to VFR at times, especially over the hilly terrain. RME and SYR, benefiting from downslope conditions will be more solidly in the VFR category. Later tonight, a cold front will bring strong convection and gusty winds, but possibly improved ceilings as mixing brings the deck up. Behind the front on Monday, expect cold advection clouds and moisture bringing widespread MVFR to the area with lowered ceilings and visibilities in rain showers. Fronts in the vicinity will bring the threat of LLWS for much of the night. Outlook... Monday evening...Restrictions with wrap-around rain showers, possibly mixing with wet snow at higher elevation sites. Monday overnight through Tuesday...becoming mostly VFR. Wednesday through Thursday...Primarily VFR. Friday...Restrictions likely with rain. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.

Strong thunderstorm winds knocked down a tree, which blocked County Road 68.
Strong thunderstorm winds knocked down hundreds of trees.
A concentrated area of straight-line wind damage from a severe |thunderstorm was first observed in Chenango Valley State Park. |Dozens of pine trees were uprooted or snapped at the trunk near the |main park entrance. Sporadic damage to trees continued as the storm |moved eastward. A large tree fell on a house on Route 221 near Moot |Town Road. Farther east, minor roof damage from strong winds |occurred at a few businesses and residential houses in Harpursville. |The last of the substantial damage occurred near the intersection of |Route 26 and Route 40 in Afton. A large portion of a roof was blown |off a house while the metal roof of a barn across the street was |torn off.
Maximum wind speeds from this downburst was estimated to be near |80 mph.
Severe thunderstorms rolled through southern Broome County early in the morning of the 15th. A microburst with estimated winds at 70 mph blew through Conklin damaging the Conklin Fire Station as a few bricks were knocked off. Numerous trees and branches were blown down in the adjacent neighborhood to the fire station.
Strong thunderstorm winds knocked down numerous trees.
Several trees were uprooted just to the west of Monkey Run Road in |Fenton which was likely close to where the tornado touched down. |The most significant damage occurred as the tornado tracked |eastward through two residential properties on Monkey Run Road. |Several dozen softwood and hardwood trees were uprooted or snapped|in its path. One house sustained moderate damage to the roof. The|roof cover that was above the deck was lofted across the back |yard. Insulation from the attic and a trampoline in the back yard |was found 250 yards away in the middle of a densely wooded area. |Damage to another house included ten broken windows, loss of |shingles and a garage door that was torn off.
Farther east, several large pine trees were uprooted or snapped |while roof shingles were torn off a house on Tunnel Road. Tree |damage became much more sporadic farther east as the tornado lifted |near Walling Road in Colesville.
