The National Weather Service conducted a storm survey on Wednesday, March 18th for the storms that occurred on Sunday night, March 15th. A tornado was determined to have occurred in Warren County with max winds of 90 MPH (EF1).

Damage was first observed along Pisgah Ridge near White Road south of Richardson Road. A nearby residence had minor shingle damage, but several farm outbuildings had significant roof damage. While most of the damage had a northeast direction with the storm motion, there was evidence of rotation. One barn roof was lofted to the northeast, however there were wood planks that were impaled into the ground in the opposite direction to the southwest. Also, a nearby shed was leaning to the northwest, which was toward the tornado circulation path. The tornado continued uphill toward more farm outbuildings where a roof was lofted to the north and to the east, which was slightly offset from the northeast storm motion and evidence of rotation. Max wind speeds in this location were estimated to be 90 mph.

The tornado continued to the northeast along Richardsville Road and damage was observed at a residence. A carport awning overhang roof was damaged and lifted to the northeast, however nearby tree damage occurred to the northwest toward the center of the tornado circulation. Winds at this location were between 80 and 90 mph.

The damage continued to the northeast along James Elkins Road where several trees had snapped damage. The nearby barn had roofing material loss, and the building was shifted and leaning to the northeast after being hit by the tornado. The roof damage was laying in several different directions and the snapped tree damage had evidence of breaking and twisting with the passing of the tornado. The tornado continued across Hall Road and toward Karl Young Road where damage to a home and nearby outbuildings occurred. The homeowner mentioned that the tornado had picked up a zero turn mower and placed it back down on top of the shed roof damage. A nearby barn was destroyed as well. Debris was lofted into a nearby field to the north and northeast of the location. Several wood plank and plywood impalements were noted facing north and west, which was continued evidence of rotation. Beyond the field north of Karl Young Road, no additional damage was observed.

The National Weather Service would like to thank Warren County Emergency Management for their assistance on the storm survey, as well as the helpful homeowners who allowed access to their properties.

Written by NWS LMK in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

38 damage points were recorded along this path by NWS LMK, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 93 mph.

• Impalement in nearby field
• Twisted branches in a few to east and southeast
• Shed is missing, likely in the nearby field destroyed and lofted
• Unit shifted but remains upright

During the late evening and overnight hours March 15th into March 16th, a strong upper level trough and associated cold front moved across the Ohio Valley. Ahead of the cold front, temperatures were in the 70s with dew point temperatures in the upper 50s and low 60s. This corridor of modest low-level destabilization contained between 250 and 500 J/kg of MLCAPE which was oriented immediately ahead of the surface front and the main line of showers and thunderstorms. With a corridor of 80 knot mid-level winds approaching from the west, effective bulk shear was between 40 and 50 knots for this event, creating a typical high-shear, low-CAPE setup for central Kentucky and southern Indiana. While the primary forcing mechanism was lifting along the cold front, resulting in a quasi-linear convective system, some scattered cells developed ahead of the main line of storms across western Kentucky. These storms had transient supercellular characteristics, and would go on to produce a swath of stronger winds and a few embedded tornadoes across Butler, Grayson, Breckinridge, Hardin, and Meade County. Elsewhere across Kentucky, scattered wind damage was produced by the main line of storms, with more favorably oriented segments of the line producing additional weak spin-up tornadoes. As the line of storms pushed east toward the I-75 corridor early in the morning on March 16th, there was a general weakening trend as MLCAPE values dropped to only around 100 J/kg across the Bluegrass. However, the portion of the line across southern Kentucky had access to slightly greater instability, resulting in additional instances of wind damage and a spin-up tornado in Clinton County. The line of storms eventually pushed into eastern Kentucky by around 3 AM on March 16th, with much cooler air rushing into the region behind the cold front.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

7 minutes of warning. NWS LMK issued a tornado warning for this county at 02:59 UTC, 7 minutes before the tornado touched down, in force until 03:34 UTC.

The county was under a tornado watch, issued at 00:27 UTC and running to 04:23 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Enhanced Risk, with a 0.05 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:43 UTC.

.SHORT TERM /THROUGH MONDAY/...
Issued at 314 PM EDT Sun Mar 15 2026

Strong, deep S/SW flow is in place ahead of a deepening low pressure
system moving across the Midwest. A potent mid/upper level trough
will continue to dig over the Midwest and MS Valley through tonight,
while a sub-990 mb sfc low lifts northeast over Lower MI. We have
seen widespread 40-50 mph gusts out of the south today, with brief
gusts of 50-60 mph across southern IN and northern KY. We did
consider an upgrade to a High Wind Warning for 60+ mph damaging
gusts, but the strongest gradient winds were occurring 17-18Z and
current ASOS/AWOS/KY Mesonet obs are all in the 35-50 mph range. The
strongest core of the LLJ also continues to lift northeast across
central IN.

This afternoon, a thin QLCS is pushing east across central MO along
the cold front. This line of very gusty showers and thunderstorms is
still expected to sweep west to east across central KY and southern
IN between 9 PM EDT - 3 AM EDT tonight. The low-level moisture
quality and sfc-based instability still look marginal (up to 250-500
J/kg SBCAPE), but the wind damage threat should be taken seriously.
The southerly LLJ ramps up significantly tonight immediately ahead
of the convective line, with 60-70 kts noted in the 1-3 km layer.
With increased turbulent mixing and convective downdrafts, scattered
to numerous instances of wind damage are expected along the leading
edge of the QLCS. Isolated 70+ mph gusts will be possible,
especially with any bows or surges along the line. Tornadoes are
also possible, but the tornado potential will be limited by the
overnight timing and waning sfc-based instability as the line pushes
east.

Showers are expected to clear the Bluegrass Region around 4 AM EDT,
with strong westerly cold air advection behind the cold front.
Expect a brief lull in precipitation, with rapidly falling
temperatures and gusty westerly winds of 25-35 mph. The upper trough
swings overhead on Monday, with wrap-around moisture pivoting across
IN and central KY. Steepening lapse rates and a cooling/moistening
profile up through 700 mb will yield scattered snow showers late
Monday morning through the afternoon hours. A quick dusting of
accumulation will be possible, perhaps up to an inch in very
localized swaths. Temperatures will struggle in the 30s through the
daytime in the CAA regime.

&&

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
Issued at 314 PM EDT Sun Mar 15 2026

It will remain somewhat breezy Monday night as temperatures fall
through the 20s, evening dropping into the mid/upper teens early
Tuesday morning across southern IN and north-central KY. Wind chills
in the single digits and teens are likely Tuesday morning.

High pressure builds across the region on Tuesday, and afternoon
temps will recover into the low to mid 30s. It will remain chilly
into Tuesday night, with lows in the low to mid 20s. Increasing SW
winds and WAA will help boost temperatures into the mid 40s to mid
50s on Wednesday ahead of a weak clipper. This system could spread
light rain and snow as far south as southern IN and central KY.
Relatively drier and warmer weather is expected heading into late
week.

&&

.AVIATION /00Z TAFS THROUGH 06Z TUESDAY/...
Issued at 745 PM EDT Sun Mar 15 2026

Winds will remain strong out of the south ahead of the approaching
cold front. Radar mosaic shows a line of strong to severe storms
working westward. Currently this line stretches from KCMI to KMVN
with another area of development out ahead of this approaching line.
These two areas merge with a main line working from HNB around 02z
to SDF/BWG around 04z to LEX/RGA around 06z. The storms themselves
could have strong damaging winds of over 50-60kts. Winds will remain
gusty with lingering rain and then a change over to snow as colder
air moves in. There may be a period of dry air with this but winds
will shift from the south to the west as the boundary moves through.
Scattered light snow along with gusty winds will be around during
the day with lingering MVFR CIG that arrive behind the passing front
during the overnight into tomorrow morning. Could see CIG return to
VFR after 18z tomorrow.
