The episode as NWS BGM wrote it up.
An intense cold front moved through Northeast Pennsylvania and Central New York 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 Harford Township in Susquehanna County and an EF0 tornado in Scranton and Dunmore in Lackawanna County. The combination of the severe thunderstorms and these tornadoes knocked down numerous trees and damaged several structures.
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 Apr 14, 7:01 PM EST, 4 hours 46 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.

Damage from the microburst was first detected to a property on Route 296 near North Baker Road. The roof from a large barn shifted off its frame with the west-facing exterior wall bowed out. The top to a nearby silo was blown over. Several large pine trees were snapped at the trunk in a cemetery on Owego Turnpike. Sporadic tree damage occurred farther northeast near Lake Ladore and Keen Lake. Interestingly, the most concentrated areas of tree damage occurred on the northern side of both lakes, possibly caused by winds accelerating off the water.
Maximum wind speeds from this microburst was estimated to be near 80 mph.
