.KEY MESSAGES...
- A few showers will be possible Saturday, mainly for areas near
  the Virginia border. Expect drier weather and more sunshine to
  return on Sunday.
- We are monitoring the evolution of Potential Tropical Cyclone
  Nine. Confidence is low on the timing and impacts, if any, for
  eastern Kentucky from this system.

.UPDATE...

Freshened grids with the latest observations, but overall there
was little in the way of changes to the forecast for this evening.

.SHORT TERM...(This evening through Saturday night)

Reviewing the 15Z surface analysis, the frontal boundaries that
impacted the area earlier this week have now tracked eastward off
the Atlantic seaboard. However, a lingering surface low pressure
center remains, positioned south of the JKL CWA and centered over
northern Georgia. Locally, the JKL CWA is currently under the
influence of weak surface high pressure.
Through the remainder of the day and the rest of the forecast
period, the slow-moving upper-level trough, which was responsible
for the convective activity earlier in the week, will continue to
influence the region as it becomes more neutral and eventually quasi-
stationary. This trough is expected to persist throughout the
period. Favorable upper-level divergence, combined with forecast
streamlines showing elevated 1000 mb to 500 mb RH values, indicates
optimal moisture transport fetch of Gulf moisture into the
southeastern portions of the CWA. This combination will favor these
locations for the highest probabilities of afternoon showers and
isolated thunderstorms. Conversely, northerly flow along the western
periphery of the trough will advect drier air into the northwestern
portions of the CWA, thereby limiting the potential for afternoon
convection in those areas. Any shower or thunderstorm that does
develop will rapidly dissipate toward sunset. Overnight clearing is
expected each night, potentially leading to locally dense valley fog.
Overall, the forecast period will be highlighted by low-end
precipitation chances, primarily across the southeastern portions of
the CWA. High temperatures are forecast to climb into the upper 70s
to low 80s, with overnight lows falling into the mid-to-upper 50s to
near 60.
.LONG TERM...(Sunday through Friday)
Issued at 245 PM EDT FRI SEP 26 2025
The main theme for the extended period is uncertainty and low
confidence on the evolution of the tropical systems specifically the
developing tropical formation over the southern Bahamas. This system
is forecast to become a tropical depression soon and move north to
northwest into the Atlantic Ocean. The ensemble analysis of shows a
much more muted system then the deterministic GFS and ECMWF.
There is also big differences between the deterministic GFS and
ECMWF on the track, timing and strength of this low.  Phasing of
this tropical storm with the persistent but weakening upper low over
the southeast United States and Appalachians is a big question.
For Sunday, ensemble analysis and deterministic models show the
upper trough closing off over the southeast United States/Southern
Appalachians. Northerly flow aloft will dry the area-mass over the
region. More sunshine and mostly dry conditions. Only the far
eastern counties have a slight chance of showers.
For next week (especially Tuesday through Friday), weakening upper
low over the southeast United States/Southern Appalachians remains
cut-off. The evolution of this upper trough/low will play a major
role in how the tropical system affect the central and southern
Appalachians. Confidence is low of tropical track, timing and
impacts over east Kentucky.
Mean ensemble QPF depicts only light amounts over east Kentucky
during this period, but again there is low confidence on rainfall
potential through much of the week.

.AVIATION...(For the 00Z TAFS through 00Z Saturday evening)
ISSUED AT 732 PM EDT FRI SEP 26 2025
A system will continue to graze far eastern and southeastern
Kentucky over the next 24 hours, with shower and thunderstorm
chances beginning to increase again for KSJS toward 09z-11z. Can`t
rule out showers and storms making it as far west as KJKL and
KLOZ Saturday, but this is too low confidence to include in the
TAFs at this time.
VFR conditions were occurring at TAF sites to begin the period,
but locally dense river fog is expected to develop after 03z. Fog
is forecast to stay largely out of the TAF sites but can`t rule
out fog leaking into a site, with KLOZ and KSME having the best
chances for such occurring. Light and variable winds will prevail
through ~16z Saturday, with a light northerly wind of 4 to 7 kts
expected afterwards through the afternoon hours.
