The episode as NWS BGM wrote it up.
A cold front moved through the area Friday the 29th, bringing scattered showers during the afternoon and evening as it tracked south across the region. Even with limited instability, strong shear supported a few thunderstorms, mainly across the Mohawk Valley and Tug Hill Plateau. The tightening pressure gradient along and behind the front also produced widespread gusty winds of 30-40 mph, especially across the higher elevations.

NWS Binghamton, NY wrote its last area forecast discussion before the first event at May 29, 6:26 PM EST, 1 hour 18 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Binghamton NY 726 PM EDT Fri May 29 2026 .WHAT HAS CHANGED... No significant changes were made from the previous forecast. && .KEY MESSAGES... 1) A cold front drops through the region this evening with a few rain showers and cooler temperatures in its wake. 2) An upper level blocking pattern will be in place for the weekend and much of next week, keeping conditions slightly cooler than normal, but mostly dry. 3) The blocking pattern erodes late next week, leading to warmer and drier conditions. && .DISCUSSION... KEY MESSAGE 1... A cold front is dropping south out of Canada and will be bringing increasing clouds later this afternoon and a few showers late this afternoon and this evening. The front, along with the showers, will exit the region overnight. NBM PoPs continue to be a bit too low, so kept previous forecast PoPs, which have 30 - 50 percent chance for rain across Central NY. The NAM indicates some mid level instability and MUCAPE values of 200 to 300 J/kg across Northern Oneida/Mohawk Valley and Tug Hill Plateau Region. Although confidence is low, there is enough instability to continue keeping a slight chance for thunderstorms in the forecast. Finally, decent thickness packing and pressure gradient along the front and surrounding it's associated low should produce gusty winds into the start of the weekend. Peak gusts are expected to exceed 25 to 30 mph for many locations and could exceed 40 mph for the higher elevations. Cold air advection on northerly flow pushes in overnight into Saturday morning with a sub- zero 850mb air briefly passing overhead. Cool air combined with the gusty winds expected Saturday morning will make it feel slightly blustery to start the day, especially for the end of May. Temperatures struggle to climb tomorrow, only maxing out in the upper 50s to mid 60s. Clear skies and cooler air overhead will lead to temperatures falling into the upper 30s to mid 40s Saturday night, but at this time, widespread frost is not expected. KEY MESSAGE 2... No major changes with the 12Z model suite as they continue to show an upper level Omega blocking pattern setting up and a trough remaining over the Northeast throughout the weekend and into next week. This will keep conditions close to or even slightly cooler than normal with highs in the 60s and low 70s and lows in the 40s. An upper low will drop south within the trough early next week. Exactly where this sets up will depend on how much of the region will observe off- and-on rain showers during this time. Isolated afternoon thunderstorms may be possible Monday and Tuesday, though most model guidance have little to no instability. Also, with the northerly flow, moisture will be limited, so any shower or storm development will be diurnally driven during peak heating in the afternoon. Despite the low drifting east, some by midweek, low chances for showers will remain in the forecast given some uncertainty in guidance on the low's location. KEY MESSAGE 3... By Thursday, the ridge over the Central US will flatten and the low over the Northeast will continue to slide eastward, leading to the Omega block eroding. Models sometimes tend to break these patterns down too quickly, so time will tell if this actually comes to fruition. If the pattern does break down, then this would result in warmer and dry conditions for the second half of the work week, with surface high pressure building in. Moisture may increase again on Friday and if there are weak perturbations pushing through, then some showers will be possible, but this is way too far out in the forecast and very low confidence at this time. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... Ceilings lowering into the MVFR category overnight from northeast to southwest in CNY. Could be a couple hour period where the ceilings alternate categories too. Ceilings should lift and burn off between 12-17Z Saturday. Westerly wind gusts actually look to be somewhat persistent through the night with a gradual shift to the north by Saturday. Outlook: Saturday night through Sunday night... Mainly VFR. Monday through Wednesday...Mainly VFR, but isolated showers each afternoon may result in brief restrictions. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && DISCUSSION...BTL/MPK AVIATION...MWG
