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.

1) Several rounds of showers and thunderstorms are expected this
afternoon and evening. Some of the thunderstorms may contain

.DISCUSSION...
KEY MESSAGE 1...

***UPDATE***

Low level wind shear along a warm front over the area is
allowing for increased tornado chances across eastern portions
of the CWA. Several tornado warnings have been issued in the
past 30 min, with 1 report of a tornado. Because of this, a
Tornado Watch has been issued.

---
Complicated setup today with many factors playing into
thunderstorm development and severe storm chances.

A strong shortwave trough moving into the western portion of the
area is driving the development of scattered showers and
storms. Cirrus blow off from storms earlier over OH has limited
the instability over this region, allowing for a few weak
storms but mostly just periods of moderate to heavy rain. East
of this area, we have seen more breaks in the clouds which has
allowed stronger CAPE to develop, with values above 1000 j/kg
currently growing from a N/S line bisecting the the Central
Finger Lakes and to the east. 0-6 bulk shear values are
currently in the 35-40kt range and should remain around this
range through the afternoon hours thanks to the strong shortwave
overhead. With the current storms moving into a much more
favorable environment, we expect some of the storms to grow and
become severe, with damaging winds and heavy rain and tornadoes
will be the main threats as the afternoon progresses.
Hodographs show tornadic signatures, with multiple swirls
located along a line of storms moving into Otsego, Delaware and
Sullivan counties. Tornadoes will be possible as these storms
develop through the afternoon hours.

Guidance suggests we may have a brief lull in activity late
this afternoon and early evening. This would bring a potential
for some clearing that could reinforce some early evening
surface instability. At the same time, a 2nd shortwave
currently over eastern MI is progged to track over the region.
This synoptic lift combined with surface instability and
increased 0-6km shear of 40-50kts would allow for more severe
storms to develop. The big question is will we get enough
clearing to introduce sufficient CAPE. If we do not and the CAPE
remains under 1000 j/kg, the amount of severe storms would be
lower but severe chances will remain given the high shear values
and synoptic lift provided by the transiting shortwave.

Heavy rains will also accompany these storms, allowing for a
potential for isolated flash flooding where multiple rounds of
storms impact an area. Currently, NEPA has a heightened chance
for isolated flash flooding with storms currently rolling
through and the expected 2nd round of storms later this
afternoon and evening.

The severe threat looks to end late this evening. Scattered rain
showers are going to linger through the night, especially north
of the Southern Tier as the trough axis moves over the area.

KEY MESSAGE 2...

With the trough lingering overhead into Wednesday, we expect
some scattered light rain showers to remain streaming across the
area.

After the trough axis moves east of the area, cool Canadian air
is expected to move into the region and plant itself through the
rest of the work week as high pressure dominates the weather
pattern. Wednesday will be the coolest, with highs in the upper
60s to mid 70s. We will see a slight warming trend through the
rest of the week, with low to mid 80s by the weekend. Showers
and storms may return Sunday or Monday as a trough tries to work
its way into the region, but it will depend on if the ridge
overhead weakens or flattens enough to allow for precip to move
in.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Scattered showers and thunderstorms are expected across the
area this afternoon and early evening. Tempos were added at each
TAF site for IFR/MVFR thunderstorms, generally from 19-23z or
00z. BGM is already getting a heavy thunderstorm, but this will
move away between 18-18:30z. Also added in PROB30 groups at RME,
SYR and ITH in the 23z to 03/04z timeframe for a possible second
round of thunderstorms, with restrictions as the next front
pushes in from the northwest.

After the bulk of the showers and thunderstorms move east of
the area in the mid to late evening, a deck of lower clouds is
expected to move in and result in at least MVFR restrictions
(mainly after 03Z). IFR restrictions will be possible late
tonight/early Wednesday morning at some of the TAF sites (RME,
and perhaps AVP).

Winds will generally be south-southwesterly throughout the TAF
period. Winds will be around 10kts and occasional gusts up to
20kts this afternoon. Locally higher gusts are possible in any
thunderstorms.

Outlook:

Wednesday Afternoon...Lingering ceiling restrictions possible;
otherwise becoming VFR.

Thursday through Sunday...Mainly VFR; morning fog at KELM may
result in restrictions.
