Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day

The local office's own words before this tornado warning went out, 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 this tornado warning went out at May 23, 7:41 PM EDT, 27 minutes earlier.

Area forecast discussion, May 23, 7:41 PM EDT, 27 minutes before
AREA FORECAST DISCUSSION
National Weather Service Binghamton NY
741 PM EDT Thu May 23 2019

.SYNOPSIS...
A cold front will push through the area this evening bring
scattered thunderstorms, followed by cooler and drier air.
Another front will approach for Saturday and will bring you
another opportunity for showers and strong thunderstorms.

&&

.NEAR TERM /THROUGH FRIDAY/...

730 PM Update...Instability has increased out ahead of the final
shortwave, which is now quickly crossing lake Ontario. MLCAPE
has reached 500-900 J/Kg, with Effective SRH values 300-400
m2/s2 and 0-6km shear increased between 60-70 kts. Convection
has fired up just ahead of this wave across Central NY and parts
of NE PA. These thunderstorms will quickly race across the
region (WNW to ESE) over the next few hours. The activity should
move out of our CWA by 10PM to Midnight. Have issued several
severe thunderstorm warnings already, and several more may be
needed...please stay weather aware this evening and have an
effective way to receive timely warnings.

600 PM Update... Have made several adjustments to the
forecast based on latest trends and high resolution models.
Bottom line is that high shear has overcome very weak CAPE
today, limiting severe weather potential, and overall
thunderstorm development. Multiple upper waves also may not have
had enough wavelength separation from each other with a second
short wave running into an area of subsidence and drying air
behind the wave that came through this morning. A third upper
wave moving from northern Michigan into Ontario has triggered
isolated activity along the Niagara Frontier. The CAMS models
continue to want to fire convection ahead of this feature this
evening. Models have not performed well today, so confidence is
much, if any, storm activity is low. That said, will still sweep
some chance PoPs across our northern counties this evening to
account for this feature and residual moderate instability
lingering in the area. Most of the southern half of our forecast
area should be relatively rain free.

Previous discussion...
Threat for severe storms highly dependent on the amount of
heating and the accompanying instability we can develop. Sat
images show plenty of clouds all the way back to Michigan, but
it does look likes some partial clearing is developing over NE
Ohio into Western NY and PA trying to work into the area. Plenty
of low level shear in place so we will continue to monitor
thunderstorms and the possibility of another Watch. Best chance
it seems like would be over the NEPA counties where better
shear and the best chance for instability exists.

Otherwise cooler air behind the front will work in this evening
and Friday. Some cold advection clouds will likely develop over
the higher terrain, mainly east of I-81 where a few sprinkles
are possible into Friday morning. Beyond that, dry conditions
will continue into Friday night as high pressure builds into the
area.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
Rather complex but ill defined system races through on Saturday
and brings yet another chance for severe weather. Warm frontal
type feature races through Saturday morning developing a few
showers and perhaps a rumble of thunder. This barely clears the
northern area as a cold front plows on from the west with more
serious convection. With the warm front still nearby, concern
would be for low level shear/helicity would be available to any
cell that develops increasing the chance for damaging storms.

Of course there are model timing difference but the front should
clear the area in the late evening or just after midnight. Front
then stalls around the Mason/Dixon line early Sunday. This
should keep most convection south of the forecast area but
there is a chance that a few showers to even thunderstorms
could sneak back into NEPA.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
Sunday night through Monday night: High pressure builds in and moves
the region with another calmer period in time for the holiday. Still
pleasant temperature wise with lows in the 50's and highs in the 70's.

Tuesday through Wednesday night: A mid-level ridge over the
southeast deflects the next system into the Great Lakes. An
associated warm front will provide the lift and moisture for some
additional shower and thunderstorm chances in this period. Higher
chances are currently present across northern portions of central
New York but that will be dependent on the strength and location of
the ridge over the southeast. Our region may see 80's by Wednesday
with ensemble guidance potentially too cool if the boundary ends up
north of our region.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
Cold front sweeping through the area this evening will bring
showers and thunderstorms, along with brief restrictions to MVFR
levels and gusty winds. Behind the front, cold advections will
lower the ceilings to MVFR in most places as a solid strato-cu
deck moves in late overnight. Drier air and mixing will return
all stations to VFR later Friday afternoon.

Outlook...
Friday night and Saturday...VFR.

Saturday night...Showers and thunderstorms with associated
restrictions likely.

Sunday through Tuesday...Mainly VFR.
