...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 500 PM EDT FOR
CENTRAL BATH...SOUTHEASTERN FLEMING AND WEST CENTRAL ROWAN
COUNTIES...

At 359 PM EDT, Doppler radar indicated thunderstorms producing heavy
rain across the warned area. Up to two inches of rain have already 
fallen across portions of the warned. More showers and storms will 
move across the warned area over the next hour. Flash flooding is 
expected to begin shortly.

Some locations that will experience flooding include...
Owingsville, Marshall, Wyoming, Peasticks, Kendall Springs, Moore's
Ferry, Craigs, Flat Creek, Odessa, Stepstone, Bourbon Furnace, Ringos
Mills, Sharkey, Slate Valley and Grange City.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.

Please report flooding to your local law enforcement agency when you
can do so safely.

AREA FORECAST DISCUSSION
National Weather Service Jackson KY
156 PM EDT Wed Aug 2 2017

.SHORT TERM...(This evening through Thursday night)
Issued at 1233 PM EDT WED AUG 2 2017

High pressure remains in place to our SE this afternoon, allowing
SW return flow into the region, promoting temps in the mid 80s and
a bit higher humidity values than previous days. A cold front is
also currently situated to our NW. Over the next 24 hours, this
cold front will continue to make its way closer to the state, as
the high pressure system shifts farther SE. SW flow will increase
throughout the column, increasing the moisture across the region
during the day Thursday.

Still expecting isolated to scattered showers and thunderstorms
through the remainder of the afternoon across the CWA, with best
chances across the northern portion, as well as across central and
western KY closer to the approaching frontal boundary. Most
convection should cease overnight with loss of daytime
heating/instability, however can't rule out an isolated storm
continuing in the northern CWA. For tomorrow, the additional
moisture and closer proximity to the frontal boundary, will prompt
another round of scattered showers and thunderstorms very similar
to that of today, with best chances in the north and to our west
in closer proximity to the approaching surface boundary. High
temps will once again be in the mid 80s, with higher humidity
values.

Once again convection should cease some overnight with the loss of
daytime heating, allowing for some clearing of skies through the
overnight. By daybreak however, clouds will quickly begin moving
back in from the west, as will precip chances, as the frontal
boundary makes its final push towards the CWA.

.LONG TERM...(Thursday night through Tuesday)
Issued at 349 AM EDT WED AUG 2 2017

Any lingering showers and thunderstorms will diminish Thursday
evening with both the loss of diurnal heating and the lack of any
larger scale forcing for ascent. This will change into Friday as an
upper low churns into the western Great Lakes, providing for weak
local height falls and subsequent large scale lift. Dewpoints will
surge into the mid-upper 60s along/ahead of the front as deep layer
southwesterly flow increases in the right-entrance region of an
upper jet rounding the base of the low. Temperatures only look to
warm into the low 80s, therefore keeping instability limited overall
in the 1-1.5 kJ/kg range. Unidirectional southwesterly 0-6 km bulk
shear of up to 35 knots may allow for a few updrafts to become
briefly organized, with perhaps a few line segments and/or splitting
cells developing ahead of the frontal boundary. Given a 1020+ mb
surface ridge moving into the Missouri Valley by evening,
southeastward propagation of the front should be quick enough to
negate a widespread flooding threat. Will likely see a few storms
produce some brief heavy rainfall as well as some gusty winds
upward of 30-40 mph.

High pressure will build into eastern Kentucky Saturday, bringing
clearing skies and cooler temperatures with highs below normal in
the upper 70s to near 80 degrees. Sunday morning will bring a few
valley temperatures in the low 50s as ridging shifts east across the
Appalachians. Isolated to scattered storms will be possible into
Sunday afternoon as return flow materializes downstream of another
wave moving through the Great Lakes. A surface low moving northeast
through the Ohio Valley will draw a warm front through eastern
Kentucky, placing the Commonwealth back in a warm sector airmass.
This will further increase rain chances for Monday into Tuesday as a
cool front approaches once again. This will keep temperatures below
normal, with highs generally in the low 80s and lows in the low-mid
60s through midweek.

.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
ISSUED AT 658 AM EDT WED AUG 2 2017

A broad and waning surface high remains in general control, with
upper level pattern generally driving the weather in the way of
clouds and convection. Isolated showers and thunderstorms are now
popping up across eastern Kentucky as we reach peak afternoon
heating, with more scattered convection across the northern half
of the state, including KSYM. Given the pop-up nature of these
storms, and their small thumbprint, did not include in TAFs at
this time, though did include VCTS throughout the afternoon at
KSYM to account for the better likelihood.

As we go into the overnight, loss of afternoon heating will lead
to the demise of convection and some cloud cover. An increase of
moisture from SW flow, in addition to some clearing clouds
overnight, could lead to fog development once more. Given
uncertainty on how this will end up impacting the TAF sites, chose
to go with an MVFR tempo group at the TAF sites between 9 and
12Z. This can be adjusted as we see how fog starts setting up
overnight. Tomorrow will feature much of the same as today, with a
mix of high clouds and diurnally driven CU producing isolated to
scattered showers and thunderstorms across the area. KSYM is
likely to be the most affected with best chances in the northern
CWA throughout the day. Winds should remain generally 5 knots or
less throughout the period unless affected by a thunderstorm.
