.SHORT TERM /THROUGH TONIGHT/...
Issued at 424 AM EST Sat Dec 6 2025

This morning, a shortwave will push southeast through the Lower Ohio
Valley, keeping low stratus overhead for most of the day. This layer
could spit a sprinkle or two, but it`s going to remain mostly dry.
Light warm air advection will help lift temperatures into the upper
30s to low 40s, helping to melt any remaining snow.

Tonight, ahead of an approaching cold front, an inverted surface
trough extending from a low over Texas will slide southeast towards
southern Indiana and central Kentucky. Low level clouds are expected
to give way to mid-level clouds. Isolated sprinkles and flurries
become possible after midnight towards Sunday morning, but model
soundings show a saturated DGZ over dry air. This will likely limit
what reaches the ground. Light WAA limit falling temperatures to the
upper 20s to mid 30s.

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Issued at 424 AM EST Sat Dec 6 2025

Sunday, as a cold front/shortwave begins to push southeast
through the CWA, model soundings show a saturated column underneath
a dry DGZ. Expect a mostly cloudy day with possible drizzle. Rain
chances currently look pretty limited. The better chance for
precipitation arrives Sunday night as a shortwave riding on the
upper trough deepens saturation. Still, any precipitation would be
extremely light.

The cold front would bring a return to northerly winds, dropping
highs on Sunday in the low 40s to low 50s to the upper teens
(southern Indiana) to low 30s (southern Kentucky) Sunday night.

On Monday, high pressure behind the front will bring clearer skies
with CAA to the CWA, but as the high passes, WAA returns for
Tuesday. This will lift temperatures in the 30s to near 40 on Monday
about 10 degrees warmer for Tuesday.

In the mid to late week time period, northwest upper flow will bring
quick moving systems to the region. A low pressure system on
Wednesday is expected to pass over the Great Lakes. The system`s
trailing cold front is likely to bring light precipitation on
Wednesday before a different low pressure system arrives Thursday.
Impacts are expected to be limited with these systems, but with
temperatures being on either side of freezing, multiple
precipitation types will likely fall.

.AVIATION /06Z TAFS THROUGH 12Z SUNDAY/...
Issued at 1245 AM EST Sat Dec 6 2025

An area of IFR and MVFR stratus over much of southern Kentucky is
expanding northward and covers BWG, RGA, and LEX. It`s nearing SDF,
but may stop just short. There is some uncertainty on how long it
will persist near SDF. TAFs may need to be amended. This layer is
expected to persist over BWG, RGA, and LEX through most of the
period. HNB is expected to remain VFR through most of the period.
Winds are expected to remain out of the southwest before backing
towards the southeast Saturday night.
