.Short Term...(This evening through Friday)
Issued at 325 PM EDT Thu Jun 6 2019

...Localized Heavy Rainfall A Threat This Afternoon/Evening...

Convection has blossomed this afternoon in a moderately unstable
airmass. Overall deep layer shear is weak, especially below 500mb so
not seeing any organization. The main threat is localized heavy
rainfall due to slow storm motion and efficient rainfall rates,
although a few of the stronger storms have produced a decent amount
of CG lightning and some weaker wind signatures. Can't rule out a
few stronger wind gusts if a core is strong enough to produce a wet
microburst, but overall not too concerned about that threat.

Overall coverage is expected to continue in the scattered to
numerous range through late evening, gradually lifting northward as
it does so. Expect to see a relative lull in precipitation coverage
(although will still keep some low pops) in overnight before another
surge in deeper moisture arrives in the pre-dawn and morning hours
of Friday ahead of the cutoff low. Will go with pretty high pops
(categorical) across southern and central KY tomorrow, with
scattered to numerous wording across southern IN and northern KY. We
look to maintain what resembles a tall/skinny CAPE profile through
tomorrow, in addition to a weak vertical shear profile. All of this
will continue to favor slow moving heavy rainfall producers. The
stronger storms will be able to produce some lightning, but will
keep those probabilities capped in the chance range. Most locations
along and south of the Ohio River should expect between .5 and 1.5
inches of rain through tomorrow evening, with locally higher amounts
possible. Southern IN looks to see the least amount of coverage
through the short term, with amounts generally less than a half an
inch.

Expect a mild overnight with temps in the upper 60s to around 70 for
lows. Highs on Friday should struggle under heavy cloud cover and
precipitation. Look for mid to upper 70s and most spots. Any
location that breaks out of the clouds for a bit will have the
chance to get into the low 80s.

.Long Term...(Friday night through Thursday)
Issued at 300 PM EDT Thu Jun 6 2019

Friday Night through Sunday...

The persistent, and near-stationary, cut-off low will take residence
over the Tennessee Valley by Friday evening. Expect to see mostly
cloudy conditions due to the close proximity to the low center with
more consistent chances of rain showers. Best chances of showers and
storms will continue to be during the afternoon/early evening hours
each day due to diurnal heating/destabilization. Convection should
be able to generate efficient rain producers given that precipitable
water values range from 1.70 to 2.00 inches through Sunday evening.
Dynamics and kinematics suggest storms should be sub-severe with the
main hazards mainly consisting of locally gusty winds and heavy
rain. Model soundings continue to indicate relatively light upper
level winds, which means that any showers and storms will be slow
movers, resulting in increased chances of localized flooding issues.
Temperatures will be more consistent as well with morning lows in
the mid to upper 60s and afternoon highs in the upper 70s to lower
80s.

Monday through Wednesday...

Models agree that the cut-off low will begin to become absorbed into
the main flow as a cold front approaches from the west. Expect more
rain and storm chances throughout Monday ahead of this feature.
Drier and more pleasant conditions are in store for Tuesday and
Wednesday as high pressure builds in the lower and mid levels.
Temperatures will cool down a bit with morning lows in the upper 50s
to lower 60s and highs reaching into the upper 70s with dew points
in the mid to upper 50s.

.Aviation...(00Z TAF Issuance)
Updated at 720 PM EDT Thu Jun 6 2019

Band of convection currently sits just north of BWG and we continue
to see storms weaken as they pinwheel northward, barely getting any
rain into even SDF or LEX. Main challenge will be trying to time
future bands as we see spokes of forcing pivot northward across
Kentucky ahead of a stacked upper low moving across Arkansas to near
Memphis.

For this evening the main issue is whether BWG will see restrictions
from thunderstorms and whether any precip can get into SDF or LEX.
BWG storms will be an issuance time decision, as the convection
could easily be too far north already by then. Will just include
VCSH without any restrictions in SDF and LEX as precip is weakening
as it pushes north.

Plenty of debris clouds will keep fog at bay tonight, and we could
turn mixy toward morning as an easterly sfc gradient tightens.
Boundary layer remains shallow with trapped moisture, so will take
ceilings down to fuel-alternate MVFR.

Another spoke of precip will swing north into BWG by mid/late
morning, and we'll carry VCTS for embedded thunder initially, then
ramp it up to TSRA later in the afternoon. Prevailing MVFR will lift
to VFR, and while there is a potential for brief IFR restrictions as
it turns more convective in the afternoon, will not mention it yet
almost 24 hrs out. Confidence in precip getting into SDF and LEX is
lower, so will limit that mention to VCSH for now. Also expect
easterly winds to crank up late in the day with gusts near 20 kt.

This hazardous weather outlook is for portions of south central
Indiana and Central Kentucky.

.DAY ONE...Tonight.

Scattered to numerous pulse thunderstorms are expected through late
this evening. These slow moving storms could produce locally
torrential downpours and flooding. Cloud to ground lightning is also
a hazard.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.

Periods of showers and thunderstorms are expected Friday through
Monday as a slow moving low pressure system moves through the outlook
area. Localized heavy rainfall will be the primary weather hazard and
repeated rainfall over areas may lead to localized flooding issues
combined with slow movement of storms. Some strong thunderstorms are
possible during the period, but organized severe weather is not
expected at this time.

.SPOTTER INFORMATION STATEMENT...

Spotters are encouraged to report rainfall and any instances of
flooding to the National Weather Service.
