.DISCUSSION...
Issued at 349 PM EDT Sat Oct 31 2026

Currently, satellite imagery and ground observations show a solid
sheet of high clouds over all of Indiana and Kentucky with some mid-
level clouds around 10k feet. At the surface, winds are fairly light
and variable out of a general southeasterly direction. Most areas
will see temperatures reach into the 70s. Some areas in southeastern
Indiana and the eastern Bluegrass may only see the upper 60s.

Tonight, a shortwave riding along the axis of the upper trough will
lift from near the Ozarks eastward into the Lower Ohio Valley.
Surface high pressure, centered to our east, keeps a flow of
moisture and southeasterly winds over the CWA. A weak low level jet
will form just to our west and try to ease into central Kentucky and
southern Indiana, but it`s expected to remain fairly weak, around 20-
35 knots in pockets. This will begin to produce showers with chances
increasing through the night. There is a decent amount of dry air
under 700 mb that any rain will have to overcome before reaching the
ground. This is expected to limit totals before rain ends Sunday
night. The best chances for rain remain near Bowling Green and in
areas farther to the southwest. The forecast currently has totals
around 0.5" in that area tapering to the north and east to just a
hundredth or two near Madison, Indiana and areas near Richmond, KY
and east.

Behind the shortwave, the next system with a couple of embedded
surface lows in a large upper trough will bring a north to south
oriented cold front towards the Lower Ohio Valley. Ahead of the
system, an increasing pressure gradient pushing on the outgoing
surface high will result in southerly winds reaching 10-15 mph on
Monday, but this will increase to 20-25 mph by Tuesday lifting highs
into the mid to upper 70s across the CWA Tuesday afternoon before
showers ahead of the front work east into the CWA Tuesday night. This
will be our better chance for rain as widespread rain and showers
are expected be east of the CWA Wednesday night. Another upper low/
showerwave could bring a quick moving shot of additional showers
Thursday night into Friday morning. In total the area is looking to
receive between 1.25 and 3.5 inches with the current forecast.

.AVIATION /00Z TAFS THROUGH 06Z MONDAY/...
Issued at 746 PM EDT Sat Oct 31 2026

VFR conditions will prevail through the early portions of the TAF

light rain will move northeast towards the region tonight, entering
the western terminals closer to 12z. Chances for rain will increase
throughout the day, with light rain prevailing across the terminals
after 19z. Ceilings will slowly lower throughout the day Sunday,
with the potential for MVFR cigs after 18z over BWG and HNB. Winds
will be light and primarily out of the SSE tonight increasing to
around 5-7 kt by 18z Sunday.
