.SHORT TERM...(Today through Sunday)
Issued at 226 AM EDT SAT OCT 3 2026

An active jet stream continues across the northern CONUS and
southern Canada, with a weak upper trough/low extending from Baja
California northeast into the central CONUS and extending
northeast through the Ohio Valley. This upper trough is providing
for a pipeline of moisture from the subtropical East Pacific
northeast into the southern and southeastern CONUS. Upper ridging
persists both upstream and downstream of this low/trough.
Meanwhile, at the surface a cold front has moved just south and
east of eastern Kentucky over the last 6 to 12 hours, with the
forecast area currently residing in the post-frontal environment
characterized by low stratus and areas of light rain.

A shortwave over northern KY currently moves east-northeast and
out of the area by midday, with weak confluent flow aloft and the
cold front remaining south of the area. Thus, expect gradually
improving skies and ceilings with little in the way of rain
through the day outside of the morning period. Highs will only
recover into the mid 60s for far eastern areas, while areas that
see partial clearing sooner will likely reach the lower 70s, such
as along and north of I-64 and areas south and west of KY Highway
15.

A rather robust shortwave digs from southwestern Canada into the
north-central CONUS this evening into Sunday, with a second
shortwave ejecting from the southern CONUS low/trough. The
combination of these two features will help allow for the cold
front to move briefly back north into eastern Kentucky Saturday
night into early Sunday. Forcing for ascent from the two
approaching waves and warm advection will allow for rain chances
to increase once again from the west and southwest during this
time before the northern shortwave pushes a second cold front
south into the area Sunday afternoon through Sunday night.

Manual edits were kept rather minimal, with the biggest change
made to lower ProbThunder grids sufficiently to remove any
mention of thunder from the Wx grids. Fairly widespread fog was
also added to the grids for tonight as warmer and drier air moves
over a cool and moist air mass at the surface.

With warm advection ahead of the two shortwaves and second cold
front, Sunday will see a recovery in high temperatures back into
the 70s across the area.


.LONG TERM...(Sunday night through Friday)
Issued at 226 AM EDT SAT OCT 3 2026

A cold front will be moving south across the area to begin the
period Sunday evening, bringing a prolonged stretch of dry
weather lasting through the upcoming week.

Monday will see the return to calm and quiet conditions across the
region. High pressure will build across the Great Lakes, before
migrating further east with time. A second high pressure system
will then build in across the Ohio Valley, sustaining our dry
weather through Friday with plentiful sunshine expected. Highs
each day through the week should be mostly in the 70s, with a few
80s returning to our southwest counties as early as Thursday.
Lows, especially on Monday and Tuesday nights, do look to be
pretty chilly in the lower 40s. A few sheltered valleys could dip
into the upper 30s, although model guidance does not really
support frost quite yet, with fog a better possibility in the
river valleys.

.AVIATION...(For the 06Z TAFS through 06Z Saturday night)
ISSUED AT 131 AM EDT SAT OCT 3 2026

A cold front has moved through the area, with mostly low MVFR or
lower cigs within the post-frontal environment across eastern
Kentucky as of 05z. Widespread MVFR to IFR conditions are
anticipated to continue through much of the overnight into
Saturday morning, although intermittent showers and low ceilings,
courtesy of low stratus, may lead to temporary localized
reductions to LIFR conditions. Ceilings will gradually improve to
VFR later this morning through the afternoon today, with
improvements first from the west and northwest, with slower
improvements farther south and east. For all TAF sites, winds
should generally remain northeasterly or variable at under 10 kts
within the post-frontal environment.
