The episode as NWS BGM wrote it up.
Dense fog quickly lifted Monday morning and scattered showers developed within its wake in a very unstable air mass. Late Monday afternoon a storm system approached the region from the west and forced a cold front into western New York and Pennsylvania. This front generated a line of showers and thunderstorms. The system quickly moved east and some of these storms became severe producing damaging winds and large hail.

NWS Binghamton, NY wrote its last area forecast discussion before the first event at Jun 5, 12:11 PM EST, 1 hour 3 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 111 PM EDT Mon Jun 5 2017 .SYNOPSIS... Periodic showers and thunderstorms will prevail through Tuesday as a storm system impacts the region today, then becomes stationary over the region. Warmer and drier weather will return towards the weekend. && .NEAR TERM /THROUGH TUESDAY/... 1000 am update... Not a lot of change from the forecast with the update this morning. Just trying to give a bit more detail to the forecast using the latest high res model guidance (mainly NAM3km and HRRR) which seem to have a decent handle on the convection rolling along the srn shore of Lake Ontario. Still expecting a more widespread area of convection to develop by early to mid afternoon (1-3pm) over wrn and w-central NY and track to the east into the early evening hours. Modest low level lapse rates, dry air entraining into the mid levels, and around 1000-1200 J/kg of Downdraft CAPE point to the threat of gusty winds within the storms. Sufficient CAPE in the hail growth zone, deep layer shear around 50 kt and wet bulb zero heights around 9kft point to the potential for large hail. Saturated soils and plenty of low level moisture (sfc dew points around 60 deg F) elevate the threat for flash flooding, but storms should be fairly transient which will limit the extent of hydro issues. Still not concerned with the potential for tornadoes as low level shear is very weak. 430 AM EDT Update... Just a couple of showers are still present over the area this morning, but over the next couple of hours expect all activity in cntrl NY and ne PA to end. The warm front that moved over the region yesterday is now stationary and is located over central NY. This has allowed sfc temps to hold fairly steady so far this morning ranging in the uppr 50s to low 60s. Dew points are near saturation due to copious amounts of low lvl moisture. The next storm system to impact the region is located over the great lakes, and we currently have zonal flow aloft. The mid-lvl low is also just to the NW of NY, with little impact attm over the area. Dense fog has developed over portions of NY/PA due to abundant amounts of low lvl moisture and a slight inversion over the region. The fog should mix out fairly quickly after sunrise this morning as the uppr level low will start to dig southward across the great lakes the and the mid-lvl low will shift further east.Sfc temps are forecast to range uppr 60s to low 70s today. Showers and and thunderstorms will likely develop early today as high dew points are present along with sfc warm temps. This will lead to destabilization most likely along the Finger Lakes region. Expect these showers to be scattered in nature. This afternoon a shortwave will be ejected over the region which will force a cold to move across the area. More organized showers are possible along this frontal boundary. During the afternoon hours MLCAPE could rise to around 1000 J/KG, 0-6 KM Bulk Shear is projected to be around 45 Knots, the upper level dynamic support large hail growth, and with dry mid-lvl air, this suggests the possibility of strong downdrafts. Thus, large hail and strong winds today is the main threat. The threat for severe weather could start as early as 17Z and last through 02Z. Showers and an occasional rumble of thunder is possible through the night. Monday's lows will be in the low to mid 50s. On Tuesday the sfc low will drift south and this will increase the chance of showers as the flow becomes NW. Showers are likely throughout the whole CWA, however the best chance for showers will be I-81 and east. Sfc temps will range in the uppr 50s to low 60s Tues afternoon. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/... 345 AM Update... Showers gradually diminish Tuesday night, yet scattered diurnally-driven showers can still be expected Wednesday through Thursday due to very cold pool of air aloft in vicinity of upper low. Cool east-northeast flow in the lower levels will depress temperatures to 10-12 degrees below climatology for highs Wednesday. Some moderation - up about 5 degrees - will occur Thursday as low level flow becomes variable, yet the upper low will also drift directly overhead posing a bit of instability aloft. So there will be a slight chance of thunder in addition to scattered showers Thursday. && .LONG TERM /FRIDAY THROUGH SUNDAY/... Approaching wave and surface front finally begins to kick the old 500mb low out of the area later Thursday and Friday. So, the chance of mainly afternoon showers and thunderstorms will lessen and daytime highs will rise. Of course, the approaching front will trigger another chance of showers and storms on Saturday, but system is progressive and should clear the area near the end of the period. && .AVIATION /18Z MONDAY THROUGH FRIDAY/... Showers and thunderstorms are developing over wrn /w-central NY and far nrn PA early this afternoon and will likely expand in coverage and intensity through 00Z. Flight conditions will range from VFR to MVFR in TS with brief gusty winds and locally heavy rain possible. Will likely see IFR restrictions later tonight with another round of rain showers by Tuesday morning and ceilings only improving to fuel alternate required or MVFR. Winds will remain light and variable through the forecast period. A gust to 30 kt or greater is possible if a thunderstorm impacts a terminal. Outlook... Tuesday night...Restrictions likely in rain showers. Wednesday-Thursday...Restrictions possible in morning fog, showers through the day...and afternoon thunderstorms. Friday...Restrictions possible in showers and storms. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
