What forecasters said that day

The local office's own words before this flash flood 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 flash flood warning went out at Jul 12, 6:53 AM EDT, 19 minutes earlier.

Area forecast discussion, Jul 12, 6:53 AM EDT, 19 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOUISVILLE KY
653 AM EDT Sun Jul 12 2015

...Updated Aviation Discussion...

.SHORT TERM (Now through Monday Night)...
Issued at 323 AM EDT Sun Jul 12 2015

...Multiple Rounds of Storms. Flooding and Severe Threat Likely...

The upper pattern will be characterized by a strong upper ridge over
the western CONUS and continually reinforced troughing over the NE
CONUS through the short term. This setup will leave the Ohio River
Valley situated in the NW flow aloft between the two upper features,
with several disturbances diving through the stronger flow. Given
strong to extreme instability developing on the periphery of the
upper ridge and the forcing/triggering from individual perturbations
in the NW flow, several rounds of strong and severe storms are
expected. The strongest storms are expected later Monday evening,
where a widespread heavy rainfall and damaging wind event is
possible. In fact, all severe weather modes are on the table through
the short term.

Today and Tonight...

The first round of scattered to numerous showers and storms are
expected this morning as redevelopment occurs. An MCV evident on
mosaic radar over central IN and an associated surface low over
eastern IL will slide SE along a stalled frontal boundary bisecting
our CWA through the morning, helping to provide focus (subtle LLJ
response) for shower/storm development. Some of these storms may be
strong with gusty winds and heavy rainfall being the main threats.
Best coverage looks to be along and north of I-64 through the
morning into midday, before the complex moves south and east out of
our region. Expect a relative lull through the late morning and
early afternoon hours as the atmosphere destabilizes. Scattered to
numerous thunderstorms are then expected to re-develop along
residual outflow boundaries/differential heating and the main
synoptic front still situated mainly across our NE CWA. Strong
instability underneath 30-35 knots of 0-6 km shear will be
supportive of some organization with multicell cluster and mini
bowing segments. Orientation of storm development/movement may also
lead to some training of heavy rain producing storms. So, main
threats will be localized hydro concerns and damaging winds.

One Note...Storms this afternoon are conditional upon clearing out
and being able to re-destabilize.

Expect coverage of storms to diminish through the late evening hours
into the overnight as triggering is lost and brief upper ridging
looks to develop over the area. Deterministic models keep an active
overnight, but am leaning toward the "quieter" hi res consensus at
this time given the lack of a defined trigger.

Look for highs west of I-65 in the upper 80s and low 90s, with highs
in the east confined to the mid 80s under better storm coverage.
Heat indices will approach 100 in the west as hot temps combine with
dew points above 70 F.

Monday - Monday Night...

...Significant Weather Event Possible...

Data continues to suggest that a significant severe weather event
will be possible across the entire CWA Monday evening into Monday
night. As was stated in the previous discussion, NW flow MCS
activity can be tricky as models tend to struggle with timing of
individual disturbances and their interaction with strong/extreme
instability. Nevertheless, something has to give between this
instability on the periphery of the upper ridge and what appears to
be a strong disturbance diving through the flow. Unfortunately, our
region has s good shot of being in the thick of things. The latest
Day 2 SPC outlook reflects this threat with a Moderate Risk.

Setup will continue to be characterized by NW flow aloft with a
likely stalled frontal boundary bisecting our CWA from NW to SE.
Strong/extreme instability will develop due to steepening mid level
lapse rates over top of surface heating and dewpoints over 70 F.
These ingredients combined with 40-50 knots of 0-6 km bulk shear
will support an organized MCS developing upstream and moving into
our area through the evening/overnight. Veering wind profiles would
also support some supercells most likely across our NE and in
vicinity of any localized differential heating boundaries.

Like the 12/00Z NAM solution of complex developing upstream and then
bowing out across our CWA as organized convection develops a cold
pool and then follows the instability gradient southward. This
solution seems to fit the given pattern/setup.

Bottom line is that all severe modes, including Flash Flooding, will
be on the table Monday evening into Monday night. Will be issuing a
"heads-up" Special Weather Statement in anticipation of the
potential hazards Monday evening. An eventual Flash Flood Watch will
probably be needed, but chose to hold off given the uncertainty of
MCS activity and the relative lull between today's
scattered/progressive activity and tomorrow's potential event.

.LONG TERM (Tuesday through Sunday)...
Issued at 300 AM EDT Sun Jul 12 2015

Main highlights in the long term are 1) severe storm chances Tuesday
2) precipitation chances mid/late week and 3) heat/humidity.

The synoptic pattern Tuesday is expected to feature the upper ridge
centered over Texas with a potent shortwave trough rotating through
the lower Great Lakes. At the surface, outflow boundaries and/or
washed out fronts are likely to be in place from Monday night's
severe storms /see above/ across the area. Given the fast mid/upper
level flow and approaching shortwave trough, there is good consensus
that we'll rapidly clear out and destabilize during the late morning
hours. The environment when the shortwave trough arrives during the
afternoon should be characterized by 2000-3000 J/kg of SBCAPE and
deep layer shear of 40 kts. Another round of strong to severe storms
are expected with damaging winds the main threat. Flash flooding may
become a concern as well if we see repeated rounds over the same
here. Regardless the the air mass will be supportive of efficient
rain producing thunderstorms. Placement remains the biggest
question, but 12.00z guidance hints that storms may initiate across
central to south-central Kentucky first, then move east/southeast.
If this scenario pans out, southern Indiana may not see as much of a
threat. Again, what happens Tuesday will be dictated on what
ultimately happens Monday night, so have kept higher POPs for most
of the area.

While we'll remain in northwesterly to zonal flow aloft Wednesday
through Friday, at this time there's not a strong signal for any
significant shortwave to move through, so precipitation chances will
be mainly in the 20-30 percent range. In fact, some areas could see
a few dry days. Though, that will allow the heat/humidity to build
and highs are expected to gradually increase during the week into
the low/mid 90s. This is especially true for the south/southwest
areas where mid-90s are looking more likely. Add in 70-73F dewpoints
and peak heat indices in the afternoon will approach 100 to
103F.

Next weekend, forecast models show the upper ridge over the
southern Plains with periodic shortwaves coming out of the northern
Plains into the Great Lakes region. Still some uncertainty in how
strong the ridge is and whether the lower Ohio Valley will remain on
the periphery. For now, a model consensus of chance POPs with highs
at or slightly above normal look good. If the ridge wins out, plan
on heat/humidity to be the main story but if it breaks down some,
then more rounds of storms would be the threat across the area.

&&

.AVIATION (12Z TAF Update)...
Updated 653 AM EDT Sun Jul 12 2015

A convective complex is sliding along and north of the I-64
corridor, impacting SDF/LEX. Expect that coverage of
showers/t-storms will be scattered at SDF at new TAF issuance, but
coverage should be high enough to include a TEMPO for brief IFR
visibility drop. LEX will likely see heavy t-storms at the start of
issuance time so will be more pessimistic through the whole morning.
BWG should only see iso-sct coverage.

Expect a lull through the late morning and early afternoon, and then
there is question as to whether we will destabiliize for more
afternoon/evening t-storms. If this occurs, it will be most likely
at LEX, where storms will be possible for much of the overnight. Too
much uncertainty at SDF to go with more than VCTS. BWG stands the
best shot at staying dry. Expect winds to mainly prevail out of the
WSW and W today around 10 mph.
