Northwest flow in the mid- and upper-levels of the atmosphere placed central Kentucky and southern Indiana on the edge of a ring of fire type pattern for several days at the end of July 2023. While most of the waves of convection remained to the north of the area thanks to building ridging aloft July 27th into the 28th, thunderstorms on July 27th clipped the Kentucky Bluegrass region.

The episode as NWS LMK wrote it up.
Northwest flow in the mid- and upper-levels of the atmosphere placed central Kentucky and southern Indiana on the edge of a ring of fire type pattern for several days at the end of July 2023. While most of the waves of convection remained to the north of the area thanks to building ridging aloft July 27th into the 28th, thunderstorms on July 27th clipped the Kentucky Bluegrass region. The primary impact from these storms were heavy amounts of rainfall, with over 5 inches of rain being reported at a CoCoRaHS station in Nicholas County. This resulted in scattered instances of flash flooding across Nicholas, Harrison, and Bourbon County, Kentucky late in the evening on July 27th into the early morning hours on July 28th. Sadly, one fatality resulted from a home being swept away in Nicholas County.
Otherwise, conditions were mainly quiet across the region until the early morning hours of July 29th, when a mid-level trough began to dig southwestward into the Ohio Valley, allowing a surface frontal boundary to sink closer to the region, placing central Kentucky and southern Indiana into a more convectively active domain. A bowing mesoscale convective system moved from the mid-Mississippi valley eastward into Kentucky and extreme southern Indiana during the late evening hours on July 29th. While this system was generally dissipating as it moved through the area, it still retained enough strength to cause sporadic wind damage across central Kentucky and southern Indiana.

Area Forecast Discussion
National Weather Service Louisville KY
1124 PM EDT Thu Jul 27 2023
.Forecast Update...
Issued at 1124 PM EDT Thu Jul 27 2023
Convection across our northern Bluegrass region has strengthened
considerably over the last hour or so. Of particular interest is a
small area of our CWA, mainly northern Scott county into Harrison
county Kentucky. Very strong convection has been persistent across
eastern Harrison county over the last hour with Doppler dual-pol
estimates of 2.5-3 inches of rainfall.
The storm has been has exhibited severe characteristics at times
with high reflectivity aloft. However, combination of a very warm
PBL with high freezing heights has led to virtually no reports of
hail thus far. The hail falling through that heavy rainfall is also
probably resulting in some melting as well. Mesoscale analysis
shows rather poor low-level lapse rates, though DCAPE values are
still over 1000 J/Kg in the region. Environmental shear is very
marginal, but PWATs are up near 2 inches. So while a marginally
severe hail threat exists, the primary severe weather hazard
overnight will be torrential rainfall, intense lightning, and flash
flooding.
Rainfall amounts of 2-3 inches will be possible over
Scott/Harrison/Nicholas/Bourbon counties over the next several
hours. Localized heavier amounts of 4 to even 5 inches can't be
ruled out before convection diminishes very late tonight.
Issued at 1020 PM EDT Thu Jul 27 2023
Convection this evening has been confined to our northeastern CWA
along our border with ILN and JKL. Storms fired along a composite
outflow boundary in this area where MLCAPEs earlier were in the 3000-
4000 J/Kg range. PWAT across the region are up near 2 inches. Bulk
shear values were and continue to be light. With a very warm PBL,
these storms were efficient rain producers with radar estimates of 2-
3 inches in spots, with possibly locally higher amounts.
The early evening convection has diminished over much of the region.
However, some redevelopment is likely over the next several hours as
new convection may tend to develop along intersecting and residual
outflow boundaries. Will be watching convection up near Covington
closely to see if it sends out additional outflows later this
evening.
In general, the best chances for additional convection overnight
look to be centered along and north of the I-64 corridor where the
aforementioned boundary exists. This boundary does extend back into
central IN. CAM guidance for the overnight period favors our
northeastern sections, though some additional scattered development
upstream over central IN is certainly possible.

.Short Term...(This evening through Friday)
Issued at 245 PM EDT Thu Jul 27 2023
---------------------------------------------------------------------
Key Messages:
- Showers and storms possible this afternoon and evening.
- Hot and Humid tomorrow with heat indices 104-110F in the afternoon.
---------------------------------------------------------------------
Now through Tonight... Temperatures are in the low 90s currently and
dew points are in the mid 70s, which means heat indices are in the
low-mid 100s in the western two-thirds of the CWA and upper 90s in
the eastern third. There was a decent storm that formed over
Southern Indiana and tracked over Jefferson and into Shelby
counties. We received some pea size hail reports and brief 30kt
gusts. The potential for storms will continue into this afternoon
and evening due to ample low-level moisture transport, although
there is a lack of forcing at mid-levels. Most model guidance
suggest the development of isolated-scattered showers and storms
this afternoon around 21Z and lasting through the evening. If a more
mature storm forms and develops a decent cold pool, this could surge
and create a high potential for storms to move south of the
Bluegrass PKWY. However, this is somewhat unlikely due to very weak
deep layer shear, which will prevent the organization of storms.
Storms are likely to stay sub-severe and the main concerns are heavy
rainfall (given PWATS near 2.0 inches), locally gusty winds, and
frequent lightning.
Storms will move through the region and dissipate around 04-06Z. The
rest of the night will be mostly dry, leaving in 15-20% PoPs until
sunrise for any lingering isolated showers. Cloud coverage will
stick around for most of the night and coupled with mid-high 70s dew
points, low temperatures in the morning are expected to be in the
mid-upper 70s.
Tomorrow... We will remain dry tomorrow with the upper-level ridge
over the region. High temperatures are expected to be in the mid-
upper 90s and dew points in the low-mid 70s. This will bring heat
indices into the mid-upper 100s. A heat advisory is out for the
entire CWA for tomorrow. Depending on the amount of convection we
receive tonight, this could bring down high temperatures tomorrow a
degree or two. However, it would not be enough to drop the heat
advisory. Tomorrow will be hot and humid. Be sure to stay hydrated,
wear protective gear, and find AC whenever possible.
Forecast Confidence... Confidence in storm development in the
afternoon and evening hours is low-medium. Confidence in
temperatures and heat indices for tomorrow is high.
.Long Term...(Friday night through Thursday)
Issued at 300 PM EDT Thu Jul 27 2023
---------------------------------------------------------------------
Key Messages:
- Hottest temperatures of the season Fri, possibly continuing into
Sat.
- Increased precip chances later Saturday & early Sunday
- Relief from the heat Sunday through early next week,
hotter with possible MCS activity by mid next week
---------------------------------------------------------------------
Friday Night - Sunday...
Our CWA will be sandwiched between the NE periphery of a strong
upper ridge, and a stronger belt of westerlies to the north. At the
surface, a frontal boundary will sink southward through our region
later Saturday into early Sunday. Tough to nail down particulars on
the shower and storm chances, however confidence is highest in the
later Saturday/early Sunday time frame just ahead of the sagging
cold front. Deep layer shear looks pretty marginal in the 20-25 knot
range, however should be unstable enough (1500-2000 J/KG) to support
a few stronger storms in more of a pulse mode.
The bigger story for Saturday will likely be the continued heat and
humidity ahead of any shower or storm development. With highs in the
mid 90s and dew points continuing in the low to mid 70s, heat
indices will once again be in the low 100s to around 105 degrees. At
this point, think it is pretty likely that we will need an
additional day of heat headlines, but still have to wade through
some lower confidence in convective potential that could bust a temp
forecast.
Showers and storm chances linger into the first part of Sunday,
however expect the bulk of the day to be drier in a post-frontal
regime, and with surface high pressure starting to build in. Most
likely place for any showers or storms would be in our south and
east CWA. HigKY...Heat Advisory until 10 PM EDT /9 PM CDT/ Friday for KYZ023>035-

083-084-089>092.hs will be notably cooler, back in the mid 80s
for most.
Monday - Thursday...
The upper pattern transitions to a NW flow regime through the early
to mid week time frame. This will result in a "cooler" stretch of
weather on Monday and Tuesday as highs stay in the mid and upper
80s, respectively. However, heat will begin to build again by
Wed/Thursday as we likely find our way back into the low 90s.
Previous discussions have noted that this pattern would allow for
some MCS potential to develop upstream and move into our region.
This is still the case, and think the most likely timeframe this
could happen would be in the Wed/Thur time frame where models seem
more active with mid level disturbances embedded in the flow. Can't
rule out some upstream activity earlier in the week, however with
surface high pressure more established over our area, an MCS
surviving into this environment would be a little less likely.

.Aviation...(00Z TAF Issuance)
Issued at 720 PM EDT Thu Jul 27 2023
Discussion...VFR conditions will predominate during this TAF period.
Current regional radar shows widely scattered storms along northern
Kentucky and southern Indiana. Most of this activity is expected to
stay far enough away from the terminals and decided to only mention
VCTS for SDF and LEX during the first two hours of the forecast.
However, an amendment or two might be necessary should convection
moves farther south. Then, calm weather will return for the
overnight hours along with light southerly flow. Tomorrow will be
another hot and humid day with mostly dry weather in place.
Extended Outlook...Another round of showers and storms could move in
to the TAF area Friday night into Saturday morning.
