Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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.

Area forecast discussion, Jul 1, 3:21 PM EDT, 8 minutes before

Area Forecast Discussion
National Weather Service Binghamton NY
321 PM EDT Sat Jul 1 2017

.SYNOPSIS...
Showers and thunderstorms will come to an end tonight. Another
quick shot of showers and storms will again be possible on
Sunday afternoon, then the weather pattern should finally quiet
down for a few days early next week courtesy of high pressure.
Warm and muggy conditions will also become more comfortable
heading into next week.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
A Severe Thunderstorm Watch remains in effect into this evening,
however, the prolific cloudiness across the region most of today
has helped to dampen any widespread threat, and we generally
expect any activity to be some passing small lines and bows.
High resolution reflectivity simulations suggest a couple areas
to focus on in opposite areas of our forecast area. Convection
will cross from the Finger Lakes to the Mohawk Valley in the
next few hours, while a secondary area is expected across
Northeast PA with disorganized convection in between. We should
be finishing up with any severe thunderstorm activity by 6 or 7
PM. The main upper trof and surface cold front then swings
through later this evening with another quick hit of showers, or
storms before midnight...then some drying works into the region
overnight with improving conditions and somewhat cooler weather.
Expecting areas of fog to develop overnight, especially in areas
where heavy rain and flooding occurred.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY/...
Near term models suggest a relative lull in most of the
convective activity on Sunday and Monday, but there are still
several weak surface, and trofs aloft to come through which will
each have a potential to trigger showers and thunderstorms on an
isolated to scattered basis. These features will definitely not
have deep moisture to work with like today, but there's still
enough uncertainty that we will have to carry low chance diurnal
PoPs each afternoon and early evening. SPC even has our NEPA
counties in a Marginal Outlook on Monday. High pressure finally
busts in for a 48 hour, or so dry spell after that.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As mentioned above, high pressure dominates the region on
Independence Day with weak ridging aloft, as well. Will start
to see a gradual warm up into the middle of the week with
widespread highs into the lower 80s by Wednesday. The surface
high shifts to the east Wednesday with a return southerly flow
helping to heat things up a bit. This will also help set up the
atmosphere for a redevelopment of showers and storms late Wed
and Thursday as an area of low pressure moves along the NYPA
region. Will need to watch this system through the next several
days as it appears to be capable of tapping into a deep
moisture source and be fairly dynamic...so there may be a hydro
concern again later next week.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
Low confidence forecast this go around with highly variable
ceilings due to low level moisture and areas of thunderstorms
passing through the region making for multi-flight category
changes. Generally speaking celings through 22Z-00Z will hoveron
the bubble of MVFR-VFR with locally worse restrictions,
especially in the vicninity of TSRA. Flight conditions should
stabilize a bit this evening as main area of storms moves east
with some drier air and prevailing VFR taking hold. Another shot
of showers during the late evening, followed by the possibility
of MVFR stratus developing and also some areas of fog where
there has been rain.

After some early morning restrictions, flight operations
improve on Sunday with most areas becoming VFR scattered to
broken.

Winds generaly S-SSW around 10 knots this afternoon, except near
thunderstorms. Wind shift occurs to the West this evening at
5-10 knots and remains this way into Sunday morning.

Outlook...

Sunday through Monday...Mainly VFR but still a small chance for
showers-thunder and associated restrictions mainly in the
afternoon hours.

Tuesday - Wednesday...mainly VFR.

Thursday...Flight restrictions possible in developing showers
and thunderstorms.

.BGM WATCHES/WARNINGS/ADVISORIES...
PA...None.
NY...None.
