The episode as NWS BGM wrote it up.
A warm front was stationary over central New York Wednesday morning and extended southward into central Pennsylvania. This warm front remained in place for much of the afternoon and created a very moist and unstable air mass. A weak wave moved across the region and interacted with the front which resulted in showers and thunderstorms developing over the area. Some of these showers and thunderstorms became severe over central New York.
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 Jul 13, 2:59 PM EST, 1 hour 9 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 359 PM EDT WED JUL 13 2016 .SYNOPSIS... Muggy conditions will persist for the next couple of days. Scattered to isolated showers will diminish in coverage over the area this evening with no rain expected overnight into Thursday morning. Showers and thunderstorms will become likely by Thursday afternoon as a cold front moves across the area. A few of the storms could be strong or marginally severe with gusty winds or hail. Isolated showers will be possible again Friday afternoon... otherwise high pressure will build over the area this weekend with dry seasonably warm weather expected. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... 255 PM EDT Update... Isolated to scattered showers and thunderstorms are starting to develop across central and western NY and central and NE PA this afternoon. These are generated by 2 separate waves moving across the region. Plenty of low lvl moisture is present along with instability, thus the combination of these two parameters and the previous two features mentioned above, should allow for an environment conducive for showers and thunderstorms to continue through the afternoon and evening. Activity should diminish near midnight. Mostly to partly cloudy skies are expected to continue as we are in sw flow aloft as waa prevails over the region. This SW flow has resulted in 850mb temps to rise to around 17 to 18 deg C, thus sfc temps will continue to be well above the seasonal norm. Sfc temps will rise into uppr 80s to low 90s. Since we have plenty of low lvl moisture, the combination of temps reaching the upper 80s to low 90s and dew points remaining in the uppr 60s to low 70s will create problematic heat indices if caution is not taken. Plan ahead if you will be outside for extended period of times. Tonight there will be a slight lull in activity before the next system moves into the region brining the next chance for precip across the area. Temps tonight will only fall into the uppr 60s to low 70s as strong waa continues over the region. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/... A mid-level short wave will track east across the Great Lakes toward the northeast during the day Thursday accompanied by a surface trough and cold front. Showers and scattered thunderstorms will develop ahead of the surface trough over the Finger Lakes east toward the Mohawk valley by early afternoon. This early convection may act to decrease solar heating during the afternoon... however models are all indicate at least some destabilization by mid-afternoon with the usual biases... ie the NAM is forecasting MLCAPES exceeding 2000 J/kg east of I-81 with 1000-1500 J/kg farther west... while GFS MLCAPES are closer to 1000 J/kg. Deep layer shear values increase to 30-35 kts with the approach of the mid-level trough. 12z 4km NAM is showing a significant bow echo-like system tracking east across central NY to the Mohawk valley Thursday afternoon... which is not completely unreasonable given the reasonably favorable stability/shear/forcing combination that will be present. These factors in combination with some forcing associated with the front and wave will be enough to trigger showers and thunderstorms with pops around 60 percent. Potential for isolated severe weather will exist and this is confirmed by margnial risk indicated by SPC. Storms will diminish and move east of the area Thursday evening. Weather will be more quiet Thursday night through Saturday. A secondary short wave and mid-level trough will track across the area Friday afternoon but the atmosphere will be dryer and more stabile than Thursday and we are expecting only scattered showers. High pressure will build in over the weekend with dry seasonably warm weather expected. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... Going with chance pops Monday and Tuesday as surface high pressure will be off the east coast and a series of weak short waves will be tracking across the area in northwest flow aloft. These systems may be able to tap some moderate instability which will be building over the Ohio Valley with thunderstorms possible. A weak surface high is expected to build across the area during the middle of next week with dry warm weather. && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/... Scattered to isolated showers will occur today as two waves aloft move across the region. Decided to put -shra in tafs for this afternoon but decided not add thunder in taf as confidence is to low attm on timing and location. For the most part taf sites should remain VFR. Tonight expect a MVFR deck to develop over the region ahead of an approaching cold front as low lvl moisture will continue to remain over the area. This MVFR deck should lift by mid day. Showers and thunderstorms are expected to develop along this fropa, however confidence is to low attm to place in tafs for Thurs. Winds will be southerly this afternoon around 5 to 12 knots, then become light and variable after sunset. Winds will increase from the SW around 5 to 10 knots Thurs afternoon. OUTLOOK... Thu night...Scattered showers and thunderstorms and associated restrictions, especially Thursday. Fri through Sat...Mainly VFR but widely scattered showers and an isolated thunderstorm possible. Sat night-Sun...VFR except for probable predawn valley fog especially KELM. Mon...Restrictions possible in -shra and TSRA. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
