The episode as NWS BGM wrote it up.
A few showers and thunderstorms moved across area early Monday morning. These showers created a moist and unstable air mass over central New York and Northeast Pennsylvania. By Monday afternoon, a cold front swept across the region and generated showers and thunderstorms. Some 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 18, 10:51 AM EST, 1 hour 34 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 1151 AM EDT MON JUL 18 2016 .SYNOPSIS... An approaching front will bring a round of thunderstorms today, some of which could be strong to severe with damaging winds and large hail, mainly late morning through afternoon. Cooler and more comfortable weather will visit Tuesday and Wednesday before heat returns for the end of the week. The midweek period looks dry, but there will be a chance of thunderstorms towards the weekend. && .NEAR TERM /THROUGH TONIGHT/... Updated at 1130 am... Band of showers with isolated thunderstorms is moving east across the area late this morning. These storms have not been severe but have produced some localized heavy downpours and some lightning. Latest SPC meso-analysis indicates MLCAPE values near to just above 1000 J/kg for areas that have not gotten rain today... with just below 1000 J/kg for areas that have seen some rain. With some clearing expected during the mid-afternoon behind this system still think that many areas could see about 1500 J/kg. Meanwhile visible satellite is showing lines of cu development acrosss western NY late this morning and suspect that this might develop into another batch of thunderstorms moving across our area late this afternoon into early this evening. Plenty of wind/shear will be available for these storms with 12z BUF sounding showing 50 kt at 500 mb and 40 kts at 700 mb, so instability will be the main question mark for this afternoon. Area remains in a slight risk for severe weather for this afternoon into this evening. Previous discussion is below. 725 am update... Lead wave of thunderstorms now carrying through northwestern PA into western NY has been very poorly handled by the models. It will likely weaken while moving across the Finger Lakes-Central Southern Tier-NY Thruway, as it runs into less unstable air. That being said, this is definitely throwing a quirk into the forecast for today. It is becoming apparent that the shortwave will not organize as much into a line as originally envisioned, except perhaps on its way east of I-81 early-mid afternoon. However, environment will still be supportive of severe weather. Instead of being a line, new cells this afternoon will probably take the form of clusters. Coverage of those cells will be hit-or-miss. 325 AM update... Severe weather potential remains our primary concern Today. Main risk is for damaging winds but large hail and even an isolated tornado cannot be ruled out. Though the models differ slightly in how to handle convection today, they have come into better agreement on timing of the shortwave aloft that will serve as the trigger. This will coincide with diurnal heating. Based on model depictions of the shortwave, which matches well with current upstream convection, the main period of concern will be late morning-early afternoon in the west-northwest (Central Twin Tiers-Finger Lakes-NY Thruway corridor), to early-mid afternoon in the east-southeast (Wyoming Valley- Poconos-Catskills). After that main wave goes through, there could still be a few solitary cells into late afternoon- early evening. As for severe parameters, if anything they have trended a little more worrisome. It has been typical for the NAM to be much higher than the GFS on CAPE values this season, but this time even the GFS peaks around 2000 J/kg, primarily due to fairly steep midlevel lapse rates which have been fairly hard to come by so far this year. Shear values are also on the high side. 0-6km bulk shear is projected into the 40-50 knot range, along with 0-3km values into the 30s knot range. The good amount of synoptic wind flow, and the generally unidirectional nature of it, would suggest potential for damaging winds via persistent line segments as mentioned by the Storm Prediction Center in the Severe Weather Outlook. Based on our expected atmospheric parameters, our local severe weather analog tool turns up several past events featuring many damaging wind reports and instances of hail, and even a couple events with isolated tornadoes. We are still designated as a slight risk for severe thunderstorms areawide, though SPC notes there will be a corridor which will be more vulnerable to damaging wind potential from northern PA northeastward. This is due to overlapping of large scale ascent from a well placed right entrance region of a jet maximum aloft, and enhanced mid level flow as evidenced by the bulk shear values. Highs will be in the 80s though with dewpoints sneaking into the mid to upper 60s which will make it more uncomfortable. Temperature details of course will be affected by the expected passing of the line of storms; if not for that, more of the area would eclipse 90 degrees. A southwest breeze ahead of the approaching front may help the combination of warmth and humidity feel a little more tolerable. Then for tonight, behind the storms and frontal passage, cool air advection and falling dewpoints will allow for lows in the upper 50s to mid 60s. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... High pressure builds in for midweek bringing fair weather under mainly sunny skies with low humidity. Temperatures will be a little cool Tuesday on NW winds behind Monday's cold front with highs mostly in the 70s to around 80 in the Wyoming Valley. This will be followed by a cool night Tuesday night with lows mostly in the low to mid 50s except some upper 40s in the Catskills. Temperatures warm a couple degrees Wednesday over Tuesday's highs with continuing mostly sunny skies. && .LONG TERM /THURSDAY THROUGH SUNDAY/... The main story for the long range will be the return of heat and humidity as high pressure moves off the coast and a SW flow develops. This will bring in some of the heat from the central part of the country. As far as details, highs Thursday climb well into the 80s for most areas with humidity levels still not too high and continuing mainly sunny skies. However by Friday into next weekend highs in the 80s to low 90s look to be accompanied by dew points well into the 60s resulting in conditions feeling quite muggy. Also, Friday through next weekend will see the return of scattered showers and thunderstorms. && .AVIATION /16Z MONDAY THROUGH FRIDAY/... Wave ahead of cold front is producing showers and thunderstorms this morning upstream of the terminals. TSRA will weaken while carrying into the NY terminals, though CB will be probable for KSYR-KRME later this morning-midday. New scattered TSRA will then develop for most terminals midday through afternoon, and these may contain strong gusts. Best estimate for timing of CB is as per TEMPO groups noted in the TAFs, but monitor for amendments due to uncertainty for specific placement. Behind the TSRA, wind will veer W-WNW into evening while slackening. OUTLOOK... Tue-Wed-Thu...VFR except for potential valley fog for KELM in predawn hours Wed and Thu mornings. Thu Night-Fri...Mainly VFR but there will be a chance of SHRA- TSRA and associated brief restrictions. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
