.Mesoscale Update...
Issued at 925 AM EDT Thu Jun 29 2023

A Severe Thunderstorm Watch has been issued in collaboration with
PAH and SPC for a portion of our western CWA including Dubois,
Crawford, Perry counties in Indiana and Hancock, Breckinridge,
Meade, Hardin, Grayson, Ohio, Butler, Edmonson, Hart, and Warren
counties in KY.

A belt of increased westerlies aloft between high pressure over
south central US and low pressure over central Canada has helped
trigger convection across NE/IA/MO and a cluster of storms in
western IL, which has now moved into SW Indiana and moving towards
KY. Initially, storms appear to be moving along an elevated
instability gradient that puts storms on a trajectory towards the
aforementioned KY counties within the Watch. Main hazards will be
large damaging hail and possible damaging winds, with several
reports of 2-3 inch hail having been observed upstream.

Diurnal heating and further destabilization should see storms become
more surface based as we move into the later morning hours and into
the afternoon. CAMs vary widely in their evolution of storms today.
The HRRR appears to be initializing best, which advertises another
round of severe storm potential this afternoon when more impressive
CAPE and shear values become realized across central KY. This will
lead to a greater damaging wind threat along with large hail and a
non-zero tornado threat within a potential bowing line of
thunderstorms that could affect the Louisville Metro and other
portions of southern Indiana and central KY from 29/20Z through
30/00Z.

.Short Term...(Today and tonight)
Issued at 325 AM EDT Thu Jun 29 2023

...Increasing Risk of Strong to Severe Storms Possible Today with
Still a Fair Amount of Uncertainty...

Summary...The potential for multiple rounds of strong to severe
storms has increased for today. The strongest storms could be
capable of producing large hail, damaging winds, and a couple of
tornadoes.

Synopsis...The combination of an upper high over the lower
Mississippi valley and tight Canadian shortwave clipping the Upper
Midwest will allow a corridor of enhanced westerlies and vorticity
advection over the western Ohio Valley today. Simultaneously, a warm
and moist airmass will be present at the surface with a well-defined
instability gradient draped across the western half of the CWA right
at the leading edge of notable low-level warm air advection.

Model Confidence/Evaluation...It is important to keep highlighting
the substantial amount of uncertainty regarding the convective
coverage, timing, and evolution of today's weather event. Therefore,
there is still low confidence on specific mesoscale details 1)as
convection has barely started (29/7Z) to manifest, 2)convective
evolution will depend on outflows and boundary interactions, and
3)best available model guidance is far from agreement. Some models
depict supercellular storms firing up along a north-to-south
oriented boundary right after sunrise over IL, or IN, with a later
upscale growth towards one or several bowing segments. Other models
indicate a linear, bowing MCS since the beginning and quieter
weather (although cloudy) during the afternoon and evening. The
official forecast is more in line with the first scenario but
recognizes the need of frequent meso-updates to account for latest
trends.

Weather Hazards...Taking into account mean thermodynamic profiles
throughout the day and the intermittent bursts of better shear values
and hodograph shapes, it seems that the main weather hazards for
today will be large hail and sub-severe winds during the first part
of the morning (29/12-15Z) which then could migrate more to a
damaging wind and isolated tornado threat as daytime heating erodes
the surface inversion. Given the hodograph shape evolution and the
fact that cellular convection actually materializes, left-moving
supercells are favored during the early morning period (hail threat)
with a transition to a splitting profile by late morning (combined
hail/tornado threat). Cold pool interactions and strengthening low
to mid level winds can also boost the damaging wind threat as bowing
segments will be more likely during the late morning/early afternoon
period.

Last but not least, there is a non-negligible risk of isolated flash
flooding where the heaviest rainfall tracks given the possibility
for convective training, highly-efficient rain rates, and wet
antecedent conditions over the western half of the CWA where today's
storms should concentrate. In addition, it is very likely that the
ongoing Heat Advisory is canceled as the rain and clouds will limit
the temperature increase to below advisory criteria.

.Long Term...(Friday through Wednesday)
Issued at 316 AM EDT Thu Jun 29 203

========================================
Key Messages
========================================

- Conditionally hot/humid conditions into the weekend
- Rounds of strong/severe storms through the weekend
- Large uncertainty in timing and tracks of storm clusters
- Excessive rainfall will be possible in some areas

========================================
Synoptic Overview
========================================

Broad upper level ridge will be centered over AR/LA at the beginning
of the period on Friday.  The Ohio Valley will be on the
northeastern periphery of this ridge with multiple perturbations
moving along the ridge axis producing episodic bouts of
strong/severe convection and heavy rainfall.  The latest guidance
suggests this ridge axis will flatten out a bit by Sunday with a
slow moving upper trough coming into the region from the west.  This
upper level trough will be slow moving, so additional rounds of
convection with heavy rainfall will be possible into early next
week.  For the later period, the upper level pattern may relax a
bit, though diurnally driven convection may continue across the
region.

========================================
Meteorological Discussion and
Sensible Weather Impacts
========================================

Friday through Saturday Night...

Generally speaking, the forecast for Friday remains highly uncertain
due to uncertainties in where convective complexes may be located or
moving during the day.  Spatial and temporal spread among the
mesoscale models remains high, which is quite common in these
situations with the CAMs.  It is possible that we may be dealing
with a convective complex at the start of the period, which some
models show.  Other solutions suggest a dry start to the day with
another convective complex moving through at some point.  The timing
and placement of convection also results in low confidence on
temperatures for Friday.

Two scenarios are possible here.  In the first case, if morning
convection occurs and is slow to clear, highs could only reach the
lower-mid 80s.  On the other hand, if convection holds off until
later in the day, we could have temperatures in the lower-mid 90s.
The NBM continues to show temps across southern KY in the mid-upper
90s Friday afternoon.  I have my doubts here for a couple of
reasons.  First, we have quite a bit of damp ground from earlier
rainfall in the week.  Second, given the recent rainfall, we have
quite lush/green vegetation which could hold back temperatures.  For
now, I have undercut temps for Friday a bit, in anticipation of some
convection coming through and augmenting highs.  I do not think
we'll have a convection free day allowing for full insolation.  As
far as the Heat Advisory is concerned, it still is possible for the
current advisory area to reach criteria, but admittingly it is a
very low confidence advisory here.  Rather than yank an advisory and
possibly have to re-issue it, I'm going to leave it in the forecast
now, but if convective trends become more clear and suggest lower
temp scenarios, we could drop that advisory in subsequent forecasts.

In terms of convective risks for Friday, this really comes down to
when storms will be coming through and the effects of convective
overturning.  The morning convection scenario outlined above would
feature heavy rainfall, damaging winds, and plenty of lightning.
Model soundings do show 35-45 kts of bulk shear across the region
which would support organized convection.  If convection ends up
developing later in the day, kinematic and thermodynamic profiles
would be supportive of supercellular and multicellular convection in
the initial stage, later congealing into a wind driven MCS.  Given
the model profiles, the SPC slight risk for Friday is reasonable
given the high amount of convective uncertainty.

For Saturday into Saturday night, we'll see the ridge axis compact a
little bit as a mid-level trough axis moves in from the west.  A
stalled out frontal boundary will be in place across the region.
With the upper level trough axis coming in, additional rounds of
strong/severe convection will be possible.  However, timing these at
this forecast period remains a low confidence forecast.   Again
temperatures for Saturday will be subject to convective trends, but
a general high in the upper 80s to the lower 90s seems most
reasonable here.

Sunday through Wednesday...

Not much change in the overall pattern is expected for Sunday as
wavy surface frontal boundary will remain in the vicinity of the
Ohio and Tennnesse valleys.  With the upper level trough axis still
to our west, more rounds of convection will be possible through
Sunday night.  Excessive rainfall may become an issue by the late
weekend depending on where convection tracks.  It's hard to say
exactly how much rainfall will occur, but a broad band of 2-4 inches
with locally higher amounts will be possible.  Highs on Sunday are
likely to be near normal with readings in the upper 80s to around 90.

Moving into next week, the pattern looks to calm down a bit as the
upper level flow looks to revert to a zonal flow with the
aforementioned frontal boundary settling further south and east. The
deamplification of the flow aloft will result in less overall bulk
shear which would suggest that at least a downturn in organized
convection looks more likely than not.  Climatological PoPs are
forecast by the NBM and for now those will be accepted.  Based on
the latest Euro and Euro ensembles, we may be able to lower those a
bit more next week in subsequent forecasts.  As for temps, more
seasonal readings are expected with afternoon highs in the upper 80s
to the very low 90s with overnight lows in the upper 60s to the
lower 70s.

========================================
Forecast Confidence
========================================

In terms of forecast confidence, we're highly confident that we'll
see unsettled weather through the long term period.  So our
precipitation forecast confidence is high.  Given the convective
uncertainties, our confidence on timing and severity of convection
remains low.  With temperatures depending on convective evolution,
our confidence remains low on temperatures for Friday/Saturday and
generally medium for Sunday through Wednesday.

.Aviation...(12Z TAF Issuance)
Issued at 647 AM EDT Thu Jun 29 2023

Impacts/Confidence:
- Medium to high confidence in short period of MVFR VIS through
sunrise due to haze. Then, VFR for all terminals.
- Medium confidence in thunderstorm chances by sunrise and later
this morning. There is a fairly good chance that storms last through
the afternoon.

Discussion...Regional radar imagery shows some pretty healthy storm
cores over Illinois and Indiana this morning, also providing some
initial evaluation of previous hi-res model guidance. The mean storm
motion today is roughly from north to south, so expect this activity
to filter in a few hours or less and possibly lasts through the
afternoon due to repeated storm propagation. However, confidence in
specific weather impacts to terminals is not as high; therefore,
only VCTS is mentioned in the code for now. Be aware that any heavy
shower/storm will be capable of brief periods of MVFR/IFR VIS due to
intense rain rates. Furthermore, there is a risk of strong to severe
storms with large hail and damaging winds being the main weather
hazards. As a result, be ready for quick TAF AMD as needed.

Extended Outlook...Another round of storms and heavy rain might be
plausible Thursday night into Friday morning, but coverage and
timing uncertainty preclude any PROB30 mention at this point.
