The episode as NWS BGM wrote it up.
A cold front moved through the area during the afternoon and evening on the 19th into a high shear environment. Unseasonable warmth with highs in the 70s combined with modest amounts of instability led to the development of a line of showers and thunderstorms ahead of the boundary. A few storms embedded in the line became severe producing isolated wind damage.
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 19, 2:54 PM EST, 1 hour 12 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 354 PM EDT Sat Apr 19 2025 .SYNOPSIS... Scattered showers and thunderstorms will be around through this evening as a cold front makes its way across the area. A brief cool down tomorrow will be followed by warmer, more springlike temperatures the rest of next week. Aside from scattered showers and thunderstorms on Monday, much of the upcoming week will be dry. && .NEAR TERM /THROUGH SUNDAY NIGHT/... 345 PM Update... A cold front currently located across eastern Ontario and stretching back through western Lake Ontario, eastern Lake Erie and into far northeastern Ohio will continue to push south and east through this evening across the CWA. Scattered showers and isolated thunderstorms will persist along and ahead of the front. The risk for thunder looks to be waning though through the rest of the afternoon and evening. There is currently about 500-1000 J/kg of surface-based CAPE with strong 0-6km bulk shear on the order of 50-60 knots. Low- level lapse rates are around 7-8 degrees C/km, but mid-level lapse rates are pretty poor. What thunder there is looks to diminish around 8PM and any showers are expected to come to an end around or shortly after midnight. Winds will shift out of the northwest tonight and overnight lows will be more seasonable, but still a few degrees above average in the upper 30s to mid 40s. Some spots in the Wyoming and Delaware River Valleys in NE PA will be in the upper 40s to near 50 degrees with the cooler air slower to push in. High pressure will be building in overhead from the northwest tomorrow with partly to mostly sunny skies. It will be a noticeably cooler day in comparison to this afternoon as winds remain out of the northwest, but the cool down is expected to be brief in nature. In fact, tomorrow looks to be the coolest day of the week before more spring-like conditions take hold. High temperatures tomorrow range from the low to mid 50s across CNY and from the mid 50s to the lower 60s from the Twin Tiers on south. As high pressure gradually slides off to the east tomorrow night, a warm front will start to approach from the southwest leading to an increase in clouds, especially across NE PA and the southern Finger Lakes region. Lows tomorrow night will be in the 30s to lower 40s. && .SHORT TERM /MONDAY THROUGH TUESDAY/... A warm frontal boundary Monday will attempt to pull northeast into the region. However, flow off of the Atlantic Ocean will bring in more of the way in terms of clouds and moisture. Given the increase in cloud cover have trended temperatures a couple of degrees cooler with most areas getting to around 60. The front looks to become occluded by Monday night increasing the lift needed for some showers to move through the area. Tuesday should see a fairly quick clearing trend as high pressure builds in. Modeled boundary layer temperatures warm quite a bit indicating most areas should get well into the 60's. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... Tuesday night looks to be the coldest night under clear skies and light winds thanks to high pressure. Most locations look to fall to around 40. High pressure looks to remain in place Wednesday and Thursday with an area of low pressure riding along a frontal boundary for Friday and Saturday. Timing of the system for Friday and Saturday still has quite a bit of variation in the ensemble guidance. For now, included chance pop for both days. Temperatures look to trend a bit warmer with highs into the 70's Thursday. Most other days of the week look to end up in the 60's. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... Scattered showers are expected across mainly the NY terminals this afternoon along and ahead of an approaching cold front. A few thunderstorms are also expected, with the main window looking to be between 19-23Z. Any thunderstorm can produce brief bouts of MVFR to IFR visibility, which we have seen already a few times today across the NY terminals. AVP will have a chance of seeing some scattered showers this evening as the activity shifts off to the south and east, but the chance for any thunder was too low to include at this time. Showers are expected to come to an end between 03-05Z, but some lingering MVFR ceilings are expected, especially at RME, SYR, ITH and BGM. Mainly VFR conditions are expected to return after 06Z tonight as high pressure begins to build in. Southwest to westerly winds this afternoon and evening will gust on average between 20-25 knots, but locally higher gusts are possible, especially with any thunderstorm. Winds will become northwesterly later tonight through tomorrow. Outlook... Sunday...Mainly VFR. Monday...Chance of showers and possible restrictions. Tuesday...Becoming mainly VFR.
