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 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Louisville, KY wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 9, 1:19 PM EDT, 1 hour 29 minutes earlier.

Area forecast discussion, Apr 9, 1:19 PM EDT, 1 hour 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
119 PM EDT Thu Apr 9 2015

...Updated Aviation Discussion...

...Forecast Update...
Issued at 1032 AM EDT Thu Apr 9 2015

Atmosphere is slowly destabilizing this morning although a late
morning/early afternoon round of showers and storms could slow this
process a bit through mid afternoon. Meanwhile, what little mid
level inverstion there was around 700-800 mb appears to be eroding
per the lastest AMDAR soundings. We are seeing a response with a few
clusters of showers/storms beginning to pop up this morning. We will
have to watch these storms to see if they are able to get organzied
or if they struggle.

Overall thinking remains unchanged on how today and tonight will
evolve. However, did make a few edits to the forecast for the
morning hours. Lowered pops intitially this morning with isolated to
scattered t-storms mainly across our western CWA where better warm
advection ascent and moisture transport currently resides. By early
afternoon, do have better coverage (40-50%) of storms as we continue
to destabilize and individual disturbances move through our SW flow.
The big question with these afternoon storms is whether or not they
will become strong/organized enough. If so, vertical wind profiles
would support supercells. This potential will be our main focus in
the very short term.

Two more rounds of strong/severe storms are then expected in the
evening and overnight, one with a pre-frontal trough and the other
with the main synoptic cold front. As mentioned in the previoud
discussion, we'll lose peak heating with the overnight storms,
however stronger forcing and dynamics should allow for a sustained
severe threat.

.SHORT TERM (Now through Friday)...
Issued at 308 AM EDT Thu Apr 9 2015

...Strong to Severe Storms Possible Today and Tonight...

As of 07z, surface analysis shows a developing low pressure over the
TX/OK panhandles with a warm front stretched east/northeastward
through southern Iowa, central Illinois and northern Indiana. Aloft,
water vapor imagery shows several ripples moving through the central
Plains into the lower Ohio Valley with deep southwesterly flow. A
potent shortwave trough was coming off the Rockies into western
Kansas. Locally, another warm/muggy night has prevailed with
temperatures holding in the upper 60s to lower 70s and dewpoints in
the low/mid 60s.

The main focus is on the severe storm potential/timing/impacts later
this afternoon through tonight as the aforementioned weather
features track through the area. Overall, synoptic features in the
09.00z guidance didn't stray too far from previous solutions. For
this morning, lingering showers/storms associated with the low-level
jet and broad warm air advection should be confined along our
northern areas. Hi-res models model generally support this thinking
as well. The best chances look to be across southern Indiana and
maybe far northern Kentucky. It will be a warm, muggy day with
highs in the lower to mid 80s. Strong south/southwest gradient winds
15-20 mph with gusts near 30 mph are anticipated this afternoon.

As the upper level trough swings north of the area this afternoon
and the 300 mb jet strengthens, large scale forcing for ascent will
increase. Soundings show MLCAPE values across the area to be
1000-2000 J/KG by afternoon in the presence of 0-6 km bulk shear of
40-50 kts. Hodographs have modest low level clockwise turning.
Expecting a round of storms to initiate ahead of the main cold front
in the mid/late afternoon to early evening hours, with a mix of
supercells and bowing line segments possible. Main threat is
damaging winds but could not rule out a few tornadoes as well. Large
hail is also possible, especially with any discrete cells that form
out ahead.

Frontal passage still looks to arrive late evening through the
overnight. These storms will also pose a severe threat, mainly
damaging winds, as broken line segments approach from the west.
We'll lose our daytime heating but sufficient dynamics and
instability will keep strong to severe storms a threat.

The surface front clears out of the way early Friday morning, though
kept slight chances in the far south/east during the morning hours.
Plan on westerly flow to bring drier air and overall quieter
conditions by Friday evening. Seasonable temperatures look on tap
with highs in the upper 60s to near 70.

.LONG TERM (Friday Night through Wednesday)...
Issued at 310 AM EDT Thu Apr 9 2015

...A Pleasant Weekend Ahead Before Another Week of Active Weather...

Saturday - Sunday...

After the cold front passes Friday, sfc high pressure will spill
into the region for the weekend providing dry, seasonal conditions.
Expect mostly sunny skies Saturday with highs in the 60s, and partly
cloudy skies Sunday with highs mostly in the lower 70s.  Low temps
will range through the 40s both Fri/Sat nights with some upper 30s
possible Fri night.

Monday - Wednesday...

A weakening cold front from a northern stream system will approach
our area late Sun night and become stationary or wash out over the
Ohio Valley Monday.  This will provide focus for showers and
storms.  Upper level ridging will attempt to work into the region
Monday possibly working to weaken the boundary and/or convection
chances, but still think rounds of scattered storms will be possible
Sun night/Monday.

Monday night models begin to significantly diverge on placement of
synoptic features which makes the forecast lower confidence.
The ECMWF is a little more aggressive in phasing upper level troughs
to our northwest for mid week.  Thus, it gives a little more of a
break in convection Monday night and then lifts a warm front north
through our area Tues night.  The GFS is slower phasing the upper
level troughs to our northwest resulting in a stalled boundary over
the region Mon/Tues and then lifting the warm front north on Wed.
Either soln paints on and off rounds of showers and storms, but the
differences make each wave and resultant storm strength/QPF hard to
pin down.  At this point given the pattern, some strong storms seem
possible for the first half of the work week.

Both long term model solns indicate another strong cold front will
push through the region by the end of the week potentially providing
strong to severe storms.

Temperatures should hover above seasonal averages by 5 to 10 degrees
next week.

&&

.AVIATION (18Z TAF Update)...
Updated at 119 PM EDT Thu Apr 9 2015

The first of wave of convection has moved through SDF and only
expect isolated showers and perhaps a rumble of thunder through the
afternoon. The main concern through much of the afternoonu will be
south winds sustained between 10 to 20 mph gusting up around 30 mph
at times. Scattered to broken clouds should stay VFR.

As we move into the evening have mention of a potential secoond
round of convection that could impact all terminals. Have included 2
hours of VCTS around sunset for now, and will amend if it
materializes.

Have more confidence in overnight convection with pre-frontal trough
and cold frontal passage and have tried to time some prevailing
thunder from just after Midnight to the pre-dawn hours at BWG/SDF.
LEX will come a couple hours later.

Cold front passes in the pre-dawn hours for SDF/BWG and around
sunrise at LEX with steady west winds.

Expect VFR outside of thunderstorms, however conditions will likely
drop into IFR visibilities in any storm. Some strong to severe
storms are possible with damaging winds and large hail threats.
