.SHORT TERM...(Today through Thursday)
Issued at 300 AM EDT WED JUN 28 2017

A period of dry and warmer weather is in store for the residents
of eastern Kentucky today and tomorrow, as a ridge of high
pressure settles over the region. High temperatures will return to
closer to normal values today and tomorrow, with max readings in
the low to mid 80s expected. Tonights lows will also be warmer,
with ridgetop temperatures forecast to fall into the lower 60s,
while the surrounding valleys bottom out in the upper 50s. Winds
will be generally light and variable with mostly clear skies also
on tap across the area through tomorrow morning. Clouds will be on
the increase Thursday afternoon, as an area of low pressure passes
by to the south of the area. A few showers and thunderstorms may
evening across the Tennessee border into our southwestern counties
Thursday afternoon.

.LONG TERM...(Thursday night through Tuesday)
Issued at 424 AM EDT WED JUN 28 2017

Moisture from the Gulf of Mexico and off the southeast coast will be
moving around the western side of surface high pressure over the
Atlantic, resulting in rising dew points in our area at the start of
the period. There should be little in the way of features on the map
locally at the start of the period, and convective precip is
expected to be mainly diurnal in nature, with very little left by
00Z on Thursday evening. Redevelopment is expected with
destabilization on Friday, but still with very limited coverage due
to lack of features.

A shortwave trough rotating around a general trough over the north
central CONUS will bring falling geopotential heights and
temporarily nudge the upper level westerlies further south,
supporting a weakening cold front to move into our area on Saturday.
This will bring the highest POP of the extended forecast period.

The upper trough lifts out to the northeast on Sunday and some
limited drying occurs as the cold front washes out with passage.
Forecast soundings suggest this will be enough to knock out
convective precip for a couple of days. However, with little change
in air mass and more sunshine, temperatures should actually climb
Sunday and Monday.

Another upper level trough moves in from the northwest on Monday
night and Tuesday, and low level moisture creeps higher. This
supports at least a mention of thunderstorms once again. However,
the highest POP will remain to our northwest.


.AVIATION...(For the 06Z TAFS through 06Z Wednesday night)

VFR conditions will prevail through out the period at all five TAF
sites. Mostly clear skies, light winds, and dry conditions will be
on tap. Valley fog is still likely, especially near bodies of
water and in our deepest and most sheltered valleys. The fog
should remain suppressed enough to not affect any of the TAF
