.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 MONDAY NIGHT/...
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 /18Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 659 PM EDT Sun Sep 28 2025
VFR conditions are expected at the terminals for the upcoming TAF
period.  Diurnal Cu field will dissipate in the next hour with clear
skies expected overnight.  Winds will be light overnight, but fog
production looks to be pretty limited overnight.  If fog were to
form, it would be most likely for a few hours at HNB and BWG.
Otherwise, sunny skies and a light northeast wind is expected for
the day on Monday.
