What forecasters said that day

The local office's own words before this special weather statement 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 special weather statement went out at Jun 13, 7:22 PM CDT, 1 hour 21 minutes earlier.

.Forecast Update...
Issued at 822 PM EDT Sun Jun 13 2021

Could still see a rogue shower or two this evening but otherwise we
can expect quiet weather for the rest of the night with clearing
skies. Given the decreasing cloud cover, light winds, low level
moisture lagging behind the front, and earlier rainfall, we should
see some patchy fog development in the Blue Grass toward morning.

Issued at 534 PM EDT Sun Jun 13 2021

Scattered storms developed earlier this afternoon in a very unstable
atmosphere with oppressive surface dew points in the lower and
middle 70s. Although there has been some isolated tree damage and
sub-severe hail, the greatest impact from these storms so far has
been flooding. K Index is in the mid 30s with PWAT of 1.8" ahead of
a cold front just south of the Ohio River, and storms northwest of
Lexington have been training along a narrow axis from western Scott
County into northeast Woodford County.

Recently many of the storms have begun to struggle as the atmosphere
becomes well worked over and mid/upper cloudiness spreads through
the area. The most robust convection recently has been along outflow
from Edmonson County to Metcalfe County. However those storms are in
a regime of even weaker effective bulk shear and mid-level lapse
rates than earlier storms, and have not grown quite as strong so far.

Still, additional widely scattered thunderstorm development can be
expected before sunset primarily from southern Kentucky to the
southern Blue Grass, especially along outflow boundaries. The best
location for any strong downdrafts will be within one or two
counties of the Tennessee state line where DCAPES are over 1000 J/kg.

&&

.Short Term...(This evening through Monday)
Issued at 230 PM EDT Sun Jun 13 2021

Cold front roughly paralleling the Ohio River just after 18Z, with a
fairly agitated Cu field and a few CB over northern Kentucky in just
the last 30 min or so. More favorable shear is passing north of our
area, but strong low-level lapse rates will support pulse convection
and some marginally severe wind gusts, mainly near an instability
axis that sits east of Interstate 65 and southeast of the Ohio
River. The strongest convection on Saturday affected the Bluegrass
region and points to the south, and that will likely be the case
again today.  Will message strong storms with gusty to locally
damaging winds.

Front is progged to push southward across Kentucky this evening, and
threats will diminish with the loss of heating. We'll clear from NW-
SE, and with less humid air filtering in tonight should be a few
degrees cooler than the last several nights.

Upper trof digs into the Great Lakes on Monday, with another weak
sfc boundary (in the cool season we would say "reinforcing cold
front") dropping south into the Ohio Valley late in the day. GFS
wants to spit out QPF in the late afternoon/early evening, but it
seems to be bringing too much mid-level moisture back into the
picture. Will stick with a dry forecast, leaving POPs at a silent 10
in the afternoon.

.Long Term...(Monday night through Sunday)
Issued at 315 PM EDT Sun Jun 13 2021

An upper level ridge stretching from the Four Corners region
northward into Saskatchewan will continue to expand Monday night
into Tuesday. This will deepen a trough across the Great Lakes and
Ohio pushing the first of two shortwaves through the region. Sfc
boundary will exit to the south Monday night/Tuesday morning. We
will be under a deep northerly flow advecting in cooler and drier
air over the region. Lows by Tuesday morning will be in the upper
50s to near 60 as afternoon highs will be near to slightly below
seasonal average in the low/mid 80s under mostly sunny skies. The
second shortwave will work across the Ohio Valley Tuesday night into
Wednesday but with limited moisture no precipitation is expected.
Sfc

Wednesday and Thursday sfc high pressure will drop southward out of
the Great Lakes and into the Ohio Valley by Thursday as the upper
level trough slides off the the east over the eastern US. Cool
mornings with lows in the low/mid 50s by Thursday morning. Highs
Wednesday and Thursday will be in the upper 70s Wednesday and near
80 on Thursday. Temperatures will start to warm back up as moisture
increases with a return southerly flow late Thursday and Friday as
weak ridging aloft noses into the region. Highs will return to the
mid/upper 80s and stay there as we go into the weekend.

Another trough and associated sfc cold front will start to work
across the Ohio Valley Friday night into the weekend and is expected
to stall across the OH/TN river valleys. This could lead to a return
of precipitation and unsettled weather for the area.

&&

.Aviation...(00Z TAF Issuance)
Issued at 657 PM EDT Sun Jun 13 2021

Although a surface cold front is still in the process of moving
through the region, the window for convection is closing rapidly as
the sun sets. Mostly clear skies and light winds can be expected for
the nighttime hours as a narrow ridge of surface high pressure noses
in. Given clearing skies, light winds, low level moisture lagging
behind the front, and earlier rainfall, will include a few hours of
MVFR BR at LEX.

Tomorrow another cold front will approach from the northwest and
cross into Kentucky by evening. However, no showers are expected
with this feature in the drier air behind today's cold front.
