What happened

The episode as NWS ILN wrote it up.

An unseasonably warm and moist air mass was in place across the region during the morning hours of March 1st. Showers and thunderstorms developed across the Ohio Valley during the early morning hours as a strong low pressure system lifted northeast into the Great Lakes region. These storms produced heavy rain, large hail and several tornadoes. A squall line then moved through the region during the mid morning hours ahead of an approaching cold front. These storms resulted in damaging winds and additional heavy rain.

What forecasters said that day

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 Wilmington, OH wrote its last area forecast discussion before the first event at Feb 28, 10:03 PM EST, 3 hours 13 minutes earlier.

Area forecast discussion, Feb 28, 10:03 PM EST, 3 hours 13 minutes before

Area Forecast Discussion
National Weather Service Wilmington OH
1003 PM EST Tue Feb 28 2017

.SYNOPSIS...
Several rounds of showers and thunderstorms will be possible
through Wednesday afternoon, as a warm front moves into the area
later today, and a cold front crosses the region tomorrow. Some
of these storms may be severe, and some of them may produce
heavy rain. Behind the cold front, cooler air will move into the
region for the rest of the week. A low pressure system will
bring a chance of snow on Thursday night, with dry weather
expected for Friday and Saturday.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Little change to previous thinking. Area is in a lull. But first
cluster thunderstorms in western Indiana will spread northeast
into the forecast area after 04Z and track across the northern
counties. Meanwhile another cluster near Memphis is forecast to
move northeast into the Tri-State around 06-07Z. Shear remains
highly favorable and will only become more pronounced overnight.
Thermodynamics will become more favorable as well as higher
theta-e air continues to get drawn into the region. All modes
of severe weather remain possible overnight including flash
flooding. Southern counties that saw a good deal of rain during
the day will be especially vulnerable to the flash flood threat.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
Models are somewhat unclear on how much of a break there will be
between the two potential rounds of severe convection -- the
initial round of storms during the overnight hours, and the
linear convection during the early to mid morning. Nonetheless,
there is good model agreement on a squall line / broken line /
QLCS developing along a pre-frontal trough. Before discussing
the line, it is important to note the changes to the environment
in front of it. Behind the initial cluster of convection,
boundary layer flow is expected to veer slightly and increase in
strength, which should allow for a slight bit of low-level
mixing (thus allowing instability to become more purely surface
based). Despite this, the preceding convection may disrupt the
thermodynamic profile aloft, leading to slightly weaker overall
CAPE values in advance of the next round of convection. Wind
flow will remain strong overall, though with slightly weaker
low-level directional shear. Thus, with the second round of
convection, the threat should shift toward damaging winds being
the most significant problem, with a secondary risk of QLCS
tornadoes or marginally severe hail. This risk will continue
through the morning from WNW-to-ESE across the ILN CWA, as the
convection moves forward. The SPC Day 2 outlook includes an ENH
risk ahead of this activity, with convection expected to clear
the forecast area during the late morning or early afternoon.
Heavy rain is certainly possible with these storms as well, but
they should be generally progressive, meaning that an additional
flash flood risk on Wednesday morning may be conditional on
where previous heavy rains have fallen.

Non-diurnal temperatures are an obvious necessity through the
forecast period, and depending on convective timing, the
temperature gradient across the ILN CWA from NW-to-SE by
mid-day Wednesday could be as much as 10-15 degrees.
Temperatures will fall more significantly Wednesday night, and
as a weak wrap-around trough moves through the Great Lakes
early Thursday morning, some light rain or snow showers will be
possible -- mainly north of I-70.

One final concern to mention is that synoptic-scale winds near
and behind the cold frontal passage on Wednesday could be gusty.
This forecast represents a significant increase from the
previous run, with gusts in the 30-35 knot range on Wednesday
afternoon. In fact, a few models (using BUFKIT momentum
transfer) suggest that gusts in the northern CWA may approach 40
knots. This may have to be looked into a little more closely
once the current weather threats have passed.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
A return to colder and more winter-like weather is expected during
the immediate long term forecast.

A clipper-like system is still forecast to dive southeast into the
Great Lakes and Ohio Valley Thursday into Thursday night. This will
bring a chance of rain and snow to the region. Precipitation chances
will be highest across the north and will also transition to all
snow overnight Thursday as temperatures fall.

Colder temperatures are in the offing on Friday in the wake of the
weather system as skies becoming partly cloudy. Highs will mostly
be in the 30s.

A ridge of high pressure will quickly push through the region early
Friday night.  Mid level ridging and WAA will be on the surface
ridges heels, which will bring some clouds and a low chance of snow
across the north.

Warmer weather will return for the upcoming weekend as low level
return southerly flow and mid level ridging take hold.

Next main weather system is expected to push through the region
Monday/Tuesday. Temperatures will warm into the 60s with the threat
for showers and thunderstorms increasing Monday/Monday night ahead
of low pressure and a cold front.

&&

.AVIATION /03Z WEDNESDAY THROUGH SUNDAY/...
MVFR to IFR ceilings will persist through the early part of the
TAF period. Thunderstorms developing to the west will spread
into the region after 04Z. Still some uncertainties in timing
and duration, but there will be multiple rounds of storms moving
through overnight and into Wednesday. Storms will bring heavy
rain with associated low visibilities as well as gusty winds.
Have attempted to time out the initial round of storms with a
TEMPO group and left a broad brush prevailing SHRA and VCTS
thereafter with the expectation of amending as the situation
becomes clearer, which admittedly may only provide a short (few
hour) lead time on changing conditions. It is possible that the
threat of storms will end earlier than what is in the TAFS.

Overnight south winds will increase in speed and become gusty,
even outside of areas of precipitation. A cold front will move
through the area towards midday. This will bring the threat of
precipitation to an end, allow for brief improvement in the
ceilings to VFR, result in veering and further strengthening to
the winds with gusts over 30 kt. MVFR ceilings will likely
spread back across the area late in the TAF period.

OUTLOOK...Wind gusts over 30 kt will likely continue into
Wednesday night and MVFR ceilings may linger as well. MVFR
ceilings and visibilities will be possible again Thursday night
into Friday morning.

Damage was first observed at a farm residence on the north side of Larkin Road, where one tree was downed and a barn was destroyed. Northeast of there, some minor tree damage was seen on State Route 72 and along tree lines in adjacent fields.

Structural damage occurred at a property on US Route 62 near the intersection with Old US 62, with several outbuildings destroyed or heavily damaged. The house at this location had minor damage, mainly to roofing materials, with shingles removed on multiple sides. One large evergreen tree was uprooted and other trees were snapped. At another property slightly northeast on US Route 62, a garage was destroyed and numerous trees behind the garage were snapped.

On Leaverton Road, a barn was partially collapsed. Two evergreen trees were also snapped and other tree damage was observed both at this location and across the field to the east. Slightly south of this location, also on Leaverton Road, several trees were downed along a low spot on the road and a fence was blown flat. Minor tree damage was also observed where the tornado crossed Smith Road and a garage door was blown in at a residence on State Route 771 with some trees snapped in the vicinity. A few trees were also damaged where the tornado crossed Monroe Road.

Tree damage was observed to be significant in several locations along Milner Road. A house on Milner Road sustained siding damage to both the east and west sides of the structure and tree damage was extensive at this property. An adjacent modular home had its roof removed and other outbuildings were damaged, with debris thrown northeast across an adjacent field.

A hay barn on Bridges Road had most of its top half removed with the top also removed from another adjacent outbuilding. A home on Big Oak Road had part of its roof removed with debris observed in an adjacent field, likely a result of damage further to the west.

The last observed damage from this tornado occurred along Cope Road, where an outbuilding was mostly destroyed and a garage had part of its roof removed. Debris was thrown across Cope Road into a field to the east and southeast.
