.UPDATE...
Issued at 851 PM EDT Sun Sep 28 2025
Diurnal Cu field has dissipated leaving the area with clear skies
this evening.  Atmospheric decoupling has started with the valleys
and typical good radiational cooling spots already dipping into the
lower 60s.  Elsewhere, readings were in the upper 60s to the lower
70s.  Another clear night with some patchy river valley fog is
expected.  Lows will be in the mid-upepr 50s on the ridges, but in
the valleys and typical cooler spots, lows in the lower 50s are
expected.  Current forecast remains in good shape.  Did a quick
refresh of the grids to bring them closer to current obs.  Updated
products will be available shortly.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 236 PM EDT Sun Sep 28 2025
Ridging aloft and surface high pressure centered just northeast of
the region has allowed for sunny skies and steady northeasterly
winds. With increased heights, temperatures are currently in the mid
80s.
As the sun sets this evening, any afternoon Cu will dissipate and
winds will become calm to light. Fog will be possible in the early
morning in the river valley areas. Otherwise, low temperatures will
be in the mid-to-upper 50s and low 60s in urban areas.
Monday and Monday night will be similar to today, mostly clear skies
and warm temperatures in the mid 80s for highs. Lows will be in the
upper 50s and low 60s.

.LONG TERM /TUESDAY THROUGH SUNDAY/...
Issued at 236 PM EDT Sun Sep 28 2025
===== Tuesday - Tuesday Night =====
Tropical Storm Imelda will be located of the coast of Georgia and
South Carolina as it begins to push off to the east-northeast and
into the Atlantic. As this happens, moisture will sling northwest
into the Appalachians. Moisture will likely not reach central
Kentucky, though eastern Kentucky will see some scattered showers.
Therefore, continuing with a dry forecast for central KY and
southern Indiana.
This tropical system will work to break down the ridging centered
over the region, which will lead to slightly decreased heights and
temperatures. Expecting to see high temperatures in the low-to-mid
80s.
===== Wednesday - Sunday =====
Broad ridging and surface high pressure will remain over the region
through the week. We will see dry weather through the end of the
weekend. Temperatures will remain in the upper 70s and low 80s, near
normal or slightly above normal for this time of year. Should be a
very pleasant week.
There is currently no forecasted precipitation over the next 7 days,
therefore, drought is forecasted to persist or worsen this week.

.AVIATION /06Z TAFS THROUGH 12Z TUESDAY/...
Issued at 137 AM EDT Mon Sep 29 2025
VFR conditions are expected at the terminals for the upcoming TAF
period. Skies are clear this morning, and a decoupled boundary layer
is producing very light (generally NE) to calm winds. High pressure
is positioned north of the region through the day, and NE winds are
forecast to increase to around 10 kt during peak heating/mixing.
Occasional gusts closer to 15 kt are also possible. A few afternoon
cumulus are possible.
