.SHORT TERM...(This evening through Wednesday night)
Issued at 340 PM EDT TUE AUG 22 2017

A cold front is presently pushing towards the Ohio river with some
showers and thunderstorms developing just ahead of this feature.
Other convection which fired along an outflow from overnight
convection is now pushing its way across eastern Kentucky. Better
bulk shear values remain across central/northern Kentucky, and as
such, activity is really weakening as it outruns the better shear.
After the present showers/storms push on through, will be a few
hours before the next round with the front pushes on through.
With lots of instability still present in central Kentucky,
hesitant to let go of the severe thunderstorm watch yet. Thus,
will hang on the watch for at least another hour or two to see how
upstream convection behaves. Damaging winds will continue to be
the main threat with the strongest storms. All of this activity
and associated front will drop south and east overnight and be on
the way out towards daybreak Wednesday. This will lead to a drier
Wednesday along with much cooler conditions. Some cloud cover may
hang on well into the afternoon before clearing late in the day.
The clear skies will allow a cool night to set up for Wednesday
night as temperatures fall back into the 50s.

.LONG TERM...(Thursday through Tuesday)
Issued at 340 PM EDT TUE AUG 22 2017

Long term forecast will be issued shortly.


.AVIATION...(For the 18Z TAFS through 18Z Wednesday afternoon)

A cold front will swing south across eastern Kentucky through this
evening and tonight and bring periods of showers and thunderstorms
to the area. These will bring reductions in visibility and
ceilings at times. As the front passes later tonight, some lower
cigs could develop late tonight bringing ceilings into the MVFR
category and possibly even IFR late. These low clouds will
dissipate by midday on Wednesday.
