.SHORT TERM /THROUGH TONIGHT/...
Issued at 420 AM EDT Thu Oct 2 2025
A positively tilted upper ridge with surface high pressure extending
southwest from New England continues to keep things quiet over the
Lower Ohio Valley. Scattered cirrus will stream to the northeast as
it rides the ridge. The Bluegrass region, being east of the upper
high (within the upper ridge), will see some of these upper clouds
dropping southeast. Anticyclonic flow around the surface high is
expected to bump surface dew points up slightly along the
Mississippi and Ohio River Valleys, mainly across western Kentucky.
This could could generated a few pop-up showers or thunderstorms as
a shortwave pushes east into the region later this
afternoon/evening. Any activity is expected to remain isolated and
along the western edge of the CWA. Soundings show a lot of dry air
near the surface with limited instability. Wind shear continues to
be weak. Highs are expected to climb into the mid to upper 80s over
most of the CWA. A few areas along the eastern edge of the CWA may
only see the low 80s.
Expect any remaining afternoon/evening shower and/or thunderstorm
activity to fade as diurnal warming is lost, but as the shortwave
continues to move east overnight, a chance for showers will remain
along our western counties in Kentucky and Indiana. Nothing severe
is expected. Scattered cloud cover will continue with another night
of near calm winds with lows falling to the mid 50s to low 60s.

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Issued at 420 AM EDT Thu Oct 2 2025
Friday through Sunday, upper ridging and surface high pressure
remain over the Lower Ohio Valley. This will keep a mostly dry and
sunny forecast in place with high temperatures in the low to mid
80s each day. Lows fall into the low 50s to low 60s each night.
Monday through Wednesday, the upper ridge slides east until it`s
running northeast of Maine and back to the southwest towards
Arizona. Northwest of the ridge an upper trough drops south over the
Pacific around an upper low over northern California and Nevada. At
the surface, the high that was over the Ohio Valley will sit off the
Atlantic Coast, and this will funnel moisture northwest over the
Southeast towards the Mississippi and Ohio Valleys ahead of an
approaching cold front. Isolated shower chances on Monday will
become scattered chances on Tuesday and Wednesday ahead of the cold
front dropping southeast through the CWA. Ahead of the front, high
temperatures are expected to be on either side of 80, but the front
is expected to limit southern Indiana and northern Kentucky highs to
the low to mid 70s on Wednesday.
Thursday, behind the front, cold air advection will move into the
region ahead of surface high pressure. Skies are expected to clear
as dew points return to the 40s.
