The episode as NWS ALY wrote it up.
An upper level trough and embedded disturbance moved through the region during the late afternoon and evening hours of Wednesday, June 26th, 2019. The passage of these features allowed for strong to severe thunderstorms to develop, resulting in numerous reports of trees and wires down. A microburst also occurred in the town of Mechanicville, with dozens of trees snapped and a little league dugout destroyed by the wind.
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 Albany, NY wrote its last area forecast discussion before the first event at Jun 26, 2:39 PM EST, 2 hours earlier.
AREA FORECAST DISCUSSION National Weather Service Albany NY 339 PM EDT Wed Jun 26 2019 .SYNOPSIS... Scattered showers and thunderstorms will move across the area this afternoon and evening, with clearing skies overnight. Mainly dry and seasonably warm weather is expected Thursday and Friday. Periods of showers and thunderstorms return to the forecast Friday night into the weekend. && .NEAR TERM /THROUGH TONIGHT/... As of 315 pm, shortwave trough now approaching central portions of NY/PA. The surface pattern is muddled, but thunderstorms have developed ahead of this trough and along a weak wind shift boundary from near Saranac Lake to Rome to Clearfield, PA. Over the local area, cumulus development has been limited owing to slightly drier air in the boundary layer. The thunderstorms have been developing in an environment of 500-1000 J/kg MLCAPE. MLCAPE will increase over the local area due to a combination of advection of slightly moister boundary layer air and slightly steeper midlevel lapse rates along with diurnal heating, although this will likely be offset by drier air mixing to the surface. The question is whether the boundary layer has become too stable over the local area to allow the storms over central NY to maintain their intensity. Some of these storms have been strong to severe. CAMs and observations suggest these showers and thunderstorms approach our western zones by 20Z and exit our eastern zones and weaken with the loss of diurnal instability by around 02Z. The dry air both near the surface and at midlevels will be a limiting factor in the coverage of convection this afternoon, but gusty winds will be possible in any taller updraft given the evaporational cooling potential due to this dry air. Some marginally severe hail cannot be ruled out in the strongest storms. Deep- layer shear values around 25-30 kt suggest marginal organization of convection in the form of multi-cells. Tonight, aside from some lingering showers and thunderstorms east of the Hudson through around 02Z, a dry night with decreasing clouds is expected with subsidence in the wake of the departing wave. Some patches of fog in low-lying areas cannot be ruled out, especially in any areas that see a downpour with thunderstorms this afternoon. Lows will be slightly elevated compared with normal. && .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... Thursday, we will start the day under subsidence from the departing wave. A slightly drier airmass will be in place as well with PWATs generally under an inch. A weak wave will be tracking across northern NY into northern New England late in the day, but should be far enough removed from the local area to spare us any noticeable weather. Expect a good deal of sunshine with high temps a bit above normal. Humidity will not be too oppressive for this time of year with dewpoints in the upper 50s to low 60s in the afternoon. Tranquil weather again Thursday night with weak high pressure over the area and lows slightly warmer than normal. Tranquil weather continues into at least the first part of Friday. Deep moisture will increase in the afternoon and evening as low to mid-level winds strengthen and bring in higher theta-e values from the west. Chances for rainfall increase late Friday into Friday night, although there is quite a bit of uncertainty. Showers and thunderstorms look to develop to our west during the day where instability is greater, with some of this activity tracking toward our northern and western zones by Friday evening. Some of this activity may spread across our forecast area by Friday night, or convectively generated vorticity maxima may generate additional convection over the local area, although possibly in a weakened state due to it encountering a more stable airmass. The NAM solution of a well- organized MCS tracking into our forecast area Friday night appears to be an outlier, and it appears more likely that we will be on the more stable side of the instability gradient. Still, enough signal to keep chance PoPs with slight chance thunder in the forecast Friday night. Much of the forecast area looks to stay dry during the daytime hours Friday. Seasonably warm weather continues Friday into Friday night with dewpoints increasing Friday night, becoming more muggy. && .LONG TERM /SATURDAY THROUGH TUESDAY/... Upper energy dropping south out of SE Canada will affect our region Saturday into Saturday night with showers and thunderstorms. Then just some lingering isolated to scattered activity Sunday as cooler and drier air moves in. Considerable cooling aloft Sunday will also support some isolated to scattered showers and a possible rumble of thunder Sunday. There will be a brief cool down into Monday before the upper energy builds east and flat upper ridging very slowly builds east into our region. There are hints that one piece of more organized upper energy could track along the leading edge of better warm advection and leading edge of the flat upper ridging around Tuesday into Wednesday but there are disagreements in timing, track and strength of low level forcing. So, after dry weather Sunday night into early Tuesday, more scattered showers and thunderstorms Tuesday into Wednesday. Highs Saturday ahead of the cold front in the 80s but cooler in higher terrain. Highs Sunday in the 70s to around 80 but some 60s in northern areas. Highs Monday in the 70s to around 80. Highs Tuesday in the upper 70s to lower 80s but cooler in higher elevations. Highs Wednesday in the lower to mid 80s but some 70s in higher terrain. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... Mainly VFR conditions are expected through the TAF period ending 18Z/27. Scattered showers and storms are possible between 22Z and 01Z as a weak cold front tracks through the region. High res guidance continues to indicate a line of storms that will move through the TAF sites with the cold front so have included a TEMPO for TSRA with MVFR to account for the thunderstorm coverage. KGFL may have some radiational fog late tonight, especially if they get some rain this evening. Winds will be from the south to west at 5 to 10 kts today outside of thunderstorms. Strong westerly wind gusts are possible where thunderstorms occur. Winds become light and variable overnight tonight. Westerly winds at 5 to 10 kt are forecast for Thursday. Outlook...

In their wake, a period of mainly dry and seasonably warm weather is expected Thursday and Friday. Minimum RH values will be generally in the 40 to 50 percent range each day. A moderate westerly breeze will develop during the day on Thursday, becoming lighter on Friday. Periods of showers and thunderstorms return to the forecast Friday night into the weekend. && .HYDROLOGY... Scattered showers and thunderstorms are expected this afternoon and evening. Activity should be progressive and deep moisture is not impressive, so the potential for flooding is low. Brief heavy downpours are always possible in thunderstorms. After a mainly dry period Thursday and Thursday night, periods of showers and thunderstorms are expected Friday night into the weekend. No significant flooding is expected at this time and all rivers and creeks should stay well within bank full. && .ALY WATCHES/WARNINGS/ADVISORIES... CT...None. NY...None. MA...None.
