Area Forecast Discussion
National Weather Service Louisville KY
759 PM EDT Sat Aug 11 2018

...Updated Aviation Discussion...

.Short Term...(This evening through Sunday)
Issued at 300 PM EDT Sat Aug 11 2018

Rest of Today - Showers and T-storms will continues to move through
Kentucky.

The CWA sits on the front of a amplified mid-level ridge. At the
surface weak low pressure sits in the Ohio River Valley. High
pressure sits over Iowa and western Illinois. A weak cold front is
currently sitting near the Ohio River and working its way slowly
south. Ahead of this front, showers and thunderstorms are starting
to form just south of the Ohio River in an environment with SBCAPE
values of 2,500 to 3,000 J/kg and little shear. These showers will
continue to expand and move south and east through Kentucky. Higher
amounts are expected in the Bluegrass and lower amounts in north-
central Kentucky. Severe weather isn't expected, but heavy rainfall
and gusty winds are possible.

Tonight - Skies clear before fog and stratus move into the Bluegrass
and south-central Kentucky.

During the overnight hours, skies will clear from the northwest. By
6z, the CWA will be mostly clear. Clouds will start filling back
over the Bluegrass and southern region of central Kentucky as a
layer of low stratus and fog is likely tomorrow morning over these
areas. Lows by morning will be in the mid 60s in southern Indiana
given extra radiative cooling and in the upper 60s through
Kentucky under the clouds.

Tomorrow - Sunshine for most with highs in the 80s.

The cold front will reach Tennessee around 12z in the morning. The
rest of the day weak high pressure will move in and skies will clear
for all but the south-eastern part of central Kentucky. That area
won't see clear skies until around sunset. With the sun, highs will
reach the 80s with southern Indiana and Louisville near 90, and
temperatures fading to the low 80s along eastern parts of the CWA.

.Long Term...(Sunday night through Saturday)
Issued at 255 PM EDT Sat Aug 11 2018

Sunday Night through Tuesday Night...

Expect a period of mainly dry weather, with NW flow aloft as the
closed low continues its slow trek eastward. Temps will run slightly
below normal through Monday night, with at least a slight break in
the humidity as dewpoints mix down into the lower/mid 60s. (Yes it
will still feel like summer!) Perhaps most important to local
stargazers, night skies should be mostly clear to allow favorable
viewing of the peak of the Perseid meteor shower. By Tuesday temps
recover to near or just above climo as a shortwave upper ridge
builds.

Wednesday through Saturday...

Forecast confidence is limited as a series of upper disturbances
will swing through the Ohio Valley. Very good chance for all areas
to see precipitation on one or more days, but the main question mark
is timing. Not much model agreement or run-to-run consistency to
bring storms in as early as Wednesday, but Thursday and/or Friday
seem to be a good bet. Will limit POPs to around 50% for now, and
with later issuances we can try to better pin down which day(s) it
will rain. By Friday night/Saturday there is better agreement that
we'll get into more of a NW flow regime.

Temps through the period will continue a milder trend by night, as
low-level moisture will limit how much overnight temps can drop.
Highs will be limited by convection, but should stay close to
normal.

&&

.Aviation...(00Z TAF Issuance)
Issued at 150 PM EDT Sat Aug 11 2018

The boundary responsible for the tstorms across the area today is
slowly continuing southward. Convective activity has all but ended
at all TAF sites except SDF and LEX.

The storm SE of SDF is moving beyond the 10mile radius and nothing
more than a possible shower is expected as smaller cells to the
north are dissipating. Wind has already shifted to the NNW.
Potential exists for MVFR conditions in the early morning hours.
Expect VFR conditions after sunrise.

LEX has a rather large cell ovhd with a northwestward extent that
will continue mdt to heavy rain and gusty winds for the next hour.
Expect IFR conditions during the storm with LIFR possible in the
heavier showers. CLearing is expected after the storms and fog
potential exists with the possibility of tempo IFR conditions early
morning to sunrise. Expect VFR conditions after sunrise.

Main concern at HNB and BWG is the potential for fog Sunday morning.
HNB did not receive any rainfall today. With the lack of fog
Saturday morning hesitation exists for forecasting IFR visibility,
although model data and crossover temp analysis show good potential
for IFR conditions. Low confidence on how low HNB will go so opted
for 2 miles before sunrise. Expect VFR conditions after sunrise. BWG
is less likely to see less than IFR conditions so was more confident
with 2 miles and low stratus cig before sunrise there. Expect VFR
conditions after sunrise there as well.
