southeast Kentucky has been cancelled. Rainfall amounts through
Monday will be less than a quarter of an inch and this will not
further exacerbate ongoing high water and flooding issues on area
rivers.

AREA FORECAST DISCUSSION
National Weather Service Jackson KY
330 AM EDT Sat Apr 22 2017

.SHORT TERM...(Today through Sunday)
Issued at 325 AM EDT SAT APR 22 2017

07z sfc analysis shows a developing area of low pressure over the
central Gulf Coast to the southwest. A warm front/inverted trough
extends northeast from this stretching across southern parts of
eastern Kentucky. This boundary and points south will likely be
the location of the heaviest rains with this system through the
next 36 or so hours. Currently, showers, mainly light, continue to
propagate over the northern portions of the CWA as they stream off
to the east northeast. Skies are overcast across the area with
just warm clouds noted on satellite. Temperatures vary from near
50 degrees over the extreme northwest portion of the CWA to Low
60s southeast on the other side of that boundary. Dewpoints vary
in a similar manner with some mid 40s seen up north and low 60s
found in the south. The winds overnight show evidence of the front
with north to northeast ones for much of the CWA north of the Hal
Rogers Parkway while to the south and east they are still
southerly.

The models are actually now in excellent agreement aloft through
the short term portion of the forecast. They all depict a slow
moving and evolving upper low closing off and dropping into the
Tennessee Valley. The clustering of the models are impressive and
lends confidence to the overall forecast through 00z Monday. As
such have favored a blended solution with emphasis on the high
resolution models for specific details on PoPs and QPF through
the first 24 hours.

Sensible weather will feature a renewed development of showers,
and even some thunderstorms across the south, this morning as the
next surge of pcpn pushes into the area. This is well depicted in
the HRRR and its timing was generally followed in the grids
through 15z. The initial batch of rain after sunup will target our
central and northern counties moreso than the south, but that
changes by afternoon as the next surge will be focused more over
the Cumberland Valley. Overall, the broad sfc low passing just
south of the CWA during the short term portion of the forecast
will be a source for showers and heavier bouts of rain through
tonight before easing off to the southeast on Sunday. While the
best chances for thunder will be in the south today and this
evening heavy rain will remain a threat in the far southeast
through Sunday afternoon. For this reason, a flash flood watch
will be issued shortly for our southern tier of counties starting
at noon today and running through 4 pm Sunday. Sustained rains
during this event over the headwaters of the Cumberland and
Kentucky Rivers will also raise the specter of river flooding
later in the weekend and into the start of next week.

Temperatures will be on the chilly side through this period with
only the far south seeing readings remotely near normal today.
After highs in the low to mid 50s today, the north could rebound
into the lower 60s on Sunday thanks to the main focus of the rain
being in the south and perhaps some sun filtering through the
clouds in the afternoon. Temperatures tonight will be fairly
uniform in the upper 40s most places - coldest north and milder
south.

Started the grids from the CONSShort and ShortBlend through the
short term portion of the forecast. Did not make much adjustment
to temperatures or dewpoints given the limited diurnal range.
However, did beef up PoPs and QPF from the blend across the south
given the certainty for rain and many surges of shower activity
during this time (thunderstorms early in the event).

.LONG TERM...(Sunday night through Friday)
Issued at 330 AM EDT SAT APR 22 2017

The upper level low will meander up the east coast Sunday night
through Tuesday with mid level heights slowly recovering through
the period as the eastern system slowly pushes farther off shore
into the Atlantic. Some lingering rain chances will hold on
Sunday night, especially in southeast Kentucky before we dry out
early Monday. This will provide a much needed dry period Monday
through Wednesday morning. Temperatures will stay cool into Monday
with highs in the 60s. As return flow kicks in Tuesday highs
should climb back into the 70s.

The next chance of rain will come late Wednesday/Wednesday night
as a shortwave trough drives another cold front across the Ohio
river valley. The front may be shearing out as it crosses the
area, so opted to stay with the lower blended pops as it may not
be a widespread rain event for the area. Regardless, a few
thunderstorms would be possible, especially up in the bluegrass
region. Whats left of the washed out front will lift back to the
north as a warm front by weeks end, with much warmer weather
surging north across the region. This is also about the time our
next system may be taking aim on the area by Friday afternoon, but
some model inconsistencies will keep the uncertainty high with the
late week system.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
ISSUED AT 210 AM EDT SAT APR 22 2017

A few, mainly light, showers will continue to pass over the area
through 12z Saturday. Look for ceilings to continue to gradually
lower into or through MVFR. These will likely makes it down to IFR
and stay there for much of Saturday, as an low pressure tracks
along a stalled frontal boundary near the Tennessee and Kentucky
border. Periods of showers - at times heavy - along with a few
thunderstorms, generally along and south of a line from KSME to
KPBX, will affect the forecast area into Saturday evening. The
worst conditions will primarily be found through the southern
part of eastern Kentucky during this event. Light and variable
winds will eventually become north to northeast at 5 to 10 kts
later this morning and continue through the rest of the period.
