Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched 6 storm reports to this flash flood warning; the first came 217 minutes after it went out.

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.

* Flash Flood Warning for...
  Clinton County in south central Kentucky...
  Cumberland County in south central Kentucky...
  Southern Metcalfe County in south central Kentucky...

* Until 715 AM CDT.

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 Jun 28, 2:34 AM CDT, 46 minutes earlier. Its key messages:

  • * Scattered showers and storms will move southeast over west-central and south-central KY this morning. These storms could produce locally excessive rainfall and flash flooding in areas that see repeated rounds of torrential rainfall. * Strong upper ridge over the region will result in the hottest temperatures of the summer for all of next week. Highs around the mid 90s, dew points in the mid/upper 70s will result in heat index values above 100 to near and even above 105. Heat related headlines will likely be needed. * High heat and humidity will continue into the Independence Day Holiday with the potential for isolated to scattered thunderstorm during the afternoon and evening.

* Scattered showers and storms will move southeast over west-central
  and south-central KY this morning. These storms could produce
  locally excessive rainfall and flash flooding in areas that see
  repeated rounds of torrential rainfall.

* Strong upper ridge over the region will result in the hottest
  temperatures of the summer for all of next week. Highs around the

  during the afternoon and evening.

&&

.SHORT TERM /THROUGH TONIGHT/...
Issued at 333 AM EDT Sun Jun 28 2026

One last convectively-induced mid-level impulse is swinging over the
Lower OH Vally early this morning. A subtle sfc boundary and low-
level moisture gradient stretches from St. Louis southeast into
south-central KY. Scattered showers and storms are already
developing along this axis, where PWATs remain 2.1-2.2 inches.
Moderate 25-30 kt WSW low-level flow and moisture transport will
feed this convective axis through the remainder of the morning
hours. This setup is likely to lead to additional convective
training across portions of west-central and south-central KY,
where a Flood Watch is now in effect through Noon EDT / 11 AM
CDT. The Flood Watch remains in effect through 8 AM EDT for
portions of SW Indiana, where scattered convection remains
possible early this morning. The Flood Watch for the rest of
southern IN and areas north of I-64 in KY (our northeastern CWA)
has been cancelled, as convection is likely to remain southwest
of these areas.

A swath of 1 to 3 inches of rainfall (fairly narrow) is expected
from NW to SE through portions of central and southern KY, centered
on a Owensboro to Columbia axis. Localized totals of 4+ inches
cannot be ruled out due to training storms, which may lead to
considerable flash flooding in isolated areas.

These showers and storms are expected to sink south of the TN border
by 15-16Z today. A few rogue cells will be possible through the
afternoon and evening, but the second half of the day will trend
drier due to increasing subsidence aloft. Mid and upper level
ridging will amplify considerably over the MS Valley and Lower OH
Valley later today into tonight.

As low clouds gradually scatter and lift into the afternoon hours,
temperatures will have an opportunity to rebound quite a bit.
Afternoon highs are forecast to top out in the mid 80s (Bluegrass
Region) to around 90 (Bowling Green and surrounding areas). With a
very humid airmass still in place (mid 70s dewpoints), afternoon
heat index values will range from the lower 90s (Bluegrass Region)
to the low 100s west of I-65. Temperatures will drop back into the
low to mid 70s early Monday morning.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 333 AM EDT Sun Jun 28 2026

As we start a new week, end the month of June, start July and head
into the 4th of July Holiday, the main weather story will be the
hottest temperatures so far this summer.

A strong sprawling 594-597 ridge will build in over the Ohio Valley
and be centered over the Commonwealth for a good portion of the
week. This will allow for daily high temperatures to climb into the
low/mid 90s through the first half and potentially the upper 90s by
the end of the week. Along with the heat will be the oppressive dew
point values into the mid to upper 70s and even near 80. The
combination of the high heat and oppressive humidity will result in
heat index values approaching Heat Advisory criteria around 105 and
potentially Excessive Heat Warning criteria by late in the week
around 110. While forecast confidence is high that the week ahead
will feature our first heatwave of the season (three or more
consecutive days above 90) and that we will likely issue heat
related headlines as early as Monday there are some potential
limiting forecast factors that lower confidence for highs into the
upper 90. The first is model bias towards towards a much warmer
solution. The NBM continues to show a heat bias and that is showing
up in the extended. The second is the saturated ground currently
over central KY and southern IN. As the heat builds in over the area
it will start to evaporate the moisture in the ground, this takes
energy out of the atmosphere and cools temperatures through the
evaporation process.

By the end of the week and into the weekend an upper level shortwave
will work along the northern peripheral of the ridge weakening it
slightly. Forecast models hint that this could be enough to
introduce isolated to scattered convection to form in the afternoon
heading into the 4th of July Holiday. While this could bring some
slight relief, the forecast remains hot and humid through the long
term.

This is potentially dangerous heat and warrants those working
outside to take longer breaks, drink plenty of water and find ways
to cool down when possible. This week is a good time to check on
those who may not have AC in their home and check on your neighbors
during the day when you can.

&&

.AVIATION /06Z TAFS THROUGH 12Z MONDAY/...
Issued at 209 AM EDT Sun Jun 28 2026

SCT thunderstorms are drifting east across southern KY early this
morning, near BWG. LEX will see showers nearby at the start of this
TAF period. However, the main aviation impact for most terminals
will be the development of IFR and low-end MVFR clouds early this
morning. These clouds will expand and lower between 06-09Z, with
most terminals returning to VFR by 17-18Z.

The other concern will be a band of SHRA/TSRA that is forecast to
set up from NW to SE centered on an axis from roughly OWB/KY8 to
EKQ. This band will train southeast over south-central KY between 08-
16Z this morning. BWG has the highest chance (80%) at seeing TSRA
impacts, including lightning and torrential rainfall. HNB should be
on the northern fringe of this activity, with a 30-40% chance for a
storm between 08-12Z. Much of this convection should remain
southwest of SDF and RGA, but there is a lower-end chance (20-30%)
for a brief shower or storm.
