.SHORT TERM /THROUGH TONIGHT/...
Issued at 341 AM EDT Sun Aug 31 2025

Today, the Great Lakes centered surface high will remain over the
Lower Ohio Valley, keeping the forecast dry and mostly sunny, but
with an upper ridge remaining over the western US and trough over
the eastern US, northwest flow will carry some high level clouds
over the CWA. This is downstream of precipitation over the Northern
Plains and Midwest. Cold air advection from northeast winds will
keep highs in the upper 70s over parts of southern Indiana to the
mid 80s in south central Kentucky.

Tonight, northwest flow will continue streaming a few high level
clouds overhead, but skies will remain mostly clear over the Lower
Ohio Valley. With northeast surface winds continuing and some
radiative cooling, temperatures are expected to drop into the 50s.

.LONG TERM /MONDAY THROUGH SATURDAY/...
Issued at 341 AM EDT Sun Aug 31 2025

Labor Day, an inverted surface trough extending through the
Tennessee Valley is expected to generate scattered showers across
southern Kentucky, mainly in the Lake Cumberland area. The global
models are a little less bullish with the precipitation, but
isolated showers and thunderstorms remain possible in the area. Most
of the CWA will remain dry. High temperatures are expected to be
slightly warmer across southern Indiana with temperatures near 80.
Farther south, across central Kentucky, the mid 80s will be more
common.

Tuesday through Thursday remains the most active part of the
forecast. Continued northwest flow pushes a shortwave into the Lower
Ohio Valley on Tuesday. Widespread scattered showers and
thunderstorms spread across the CWA with the best chances over the
Bluegrass and Lake Cumberland regions Tuesday night and Wednesday.
A cold front, arriving early Thursday, will bring an end to
precipitation chances. Tuesday and Wednesday will see highs in the
mid 70s to low 80s before Thursday`s cold front limits highs to the
upper 60s to low 70s along and north of Interstate 64.

Next weekend continues to look nice with more high pressure moving
into the area. Sunny skies will slowly lift temperatures day by day
from the low to upper 70s on Friday to the upper 70s to mid 80s by
Sunday.
