The episode as NWS BGM wrote it up.
A stationary upper level storm system located over Quebec forced a weak wave across the northeast United States Monday afternoon. This wave initiated a few showers and thunderstorms across central New York. A couple of these storms became severe.
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 15, 2:26 PM EST, 44 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 326 PM EDT FRI JUL 15 2016 .SYNOPSIS... A cold front will drop south across NY and stall near the NY-PA border overnight. Isolated to scattered showers with a few thunderstorms will form ahead of this front into this evening and also again Saturday as the front eventually moves south of northeast PA. High pressure with less humidity will build into the region for Sunday. && .NEAR TERM /THROUGH SATURDAY NIGHT/... Scattered showers and isolated thunderstorms were moving across north central NY into the western Catskills and far northeast PA. This activity has fired in response to an upper level wave which was moving northeast across the eastern Great Lakes toward southern Quebec. SPC analysis shows mixed layer CAPEs of between 500 J/kg and 1000 J/kg as cold air advection occurs aloft above strong July heating. Dewpoints dropped to the upper 50s to around 60F prior to the showers limiting instability so activity was mainly showers with isolated thunder. As this wave moves northeast more showers and isolated thunderstorms will move into north central NY to the western Catskills. This activity will wind down after sunset. Then another short wave will pass by late tonight and could bring a few light showers mainly to north central NY as it pushes a weak boundary southward to the NY-PA border by 12z. Otherwise it will be a dry night. Then for Saturday yet another wave will arrive during max heating and trigger scattered showers and a few thunderstorms. This wave will push the front farther south Saturday afternoon. Again, dewpoints will be around 60F with projected CAPEs similar to today of between 500 and 1000 J/kg. So we have chance POPs Saturday mainly in the afternoon with higher chances farther south Saturday vs Today closer to boundary which will be sinking southward into northern PA. For Saturday night, upper level trough moves east overnight and and thus trended down POPs as all precipitation should die off after midnight. && .SHORT TERM /SUNDAY AND MONDAY/... High pressure at the surface will be in place across the region Sunday with quasi-zonal flow aloft likely producing a layer of high clouds...and keeping the weak/cool cyclonic flow around enough to keep temperatures in the lower to mid 80s. An upper level trough begins to dig southward through the Great Lakes late Sunday night and early Monday with showers and storms spreading NW to SE through central NY and NE PA. A warming and unstable air mass ahead of the front will allow conditions to become favorable for possibly strong storms later in the day Monday. Temperatures will warm into the mid to upper 80s on Monday with dewpoints in the 60s making it feel even warmer. && .LONG TERM /MONDAY NIGHT THROUGH THURSDAY/... Another push of slightly cooler and drier behind the front will allow temperatures to rebound back into the upper 70s and lower 80s on Tuesday with lingering light rain showers and isolated weak storms in the morning. High pressure building into the region through the middle of the week will keep weather conditions quiet through at least Thursday. Temperatures will gradually warm into the second half of the week...from the low 80 into the upper 80s. Overnight lows will trend upwards as well...from the upper 50s and lower 60s early in the week, to the upper 60s close to 70 by the end of the work week. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... VFR conditions will prevail into this evening. There will be mainly VFR cumulus under some higher clouds. There will be isolated showers and storms around that could restrict visibility to MVFR/IFR briefly at KSYR/KRME and KITH. The storms will die off by sunset. Then a lower cloud shield is projected to work into north central NY later tonight with a boundary and we are projecting MVFR CIG from RME- ELM and points north and west. All ceilings and vsbys will go to VFR by late morning on Saturday. No major issues overnight as skies will be partly cloudy with mostly VFR. The only exception will be KRME where fog will be possible due to Thursday's rain. Continue to indicate TEMPO MVFR visbys there. For Friday, expect a scattered to broken deck of Cu near 5 k ft to develop with the some isolated to scattered afternoon showers and storms. However, confidence not high enough to warrant inclusion in TAFs. Winds will be light overnight...generally around 5 knots or less. For Friday west winds increase to around 10 knots with gusts up to 20 knots. Winds will be west to southwest 5 to 15 knots this afternoon and light tonight and more west to northwest 5-10 knots Saturday morning in NY and remain west to southwest in ne PA. OUTLOOK... Sat PM...Mainly VFR but widely scattered afternoon showers and an isolated thunderstorm possible...mainly for central NY. Sat night-Sun...VFR except for probable predawn valley fog especially KELM. Mon and Tue...Restrictions possible in -shra and TSRA. Wed...VFR. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
