.UPDATE...
Issued at 1150 PM EDT WED MAY 6 2026

No significant changes were made to the forecast with mainly just
the inclusion of the latest obs and trends for the T/Td/Sky grids
and a tweaking of PoPs and drizzle into the late night. These
minor adjustments have been sent to the NDFD and web servers along
with a freshening of the zones.

UPDATE Issued at 740 PM EDT WED MAY 6 2026

23Z sfc analysis shows a cold front settling southeast through
eastern Kentucky this evening. Showers and patches of drizzle
follow this boundary with a gradual drying trend ensuing from
northwest to southeast. Currently, under plenty of low clouds,
temperatures are running in the low to mid 50s through the area.
Meanwhile, amid northwest winds of around 5 mph, drier air is
inbound from the northwest where dewpoints are generally in the
low to mid 40s while low and mid 50s are noted to the southeast.
Have updated the forecast mainly to add in the latest obs and
trends for the T/Td/Sky grids while tweaking the PoPs per the
current radar and CAMs guidance. Did also take out the thunder
chances for the rest of the night. These adjustments have been
sent to the NDFD and web servers along with a freshening of the
HWO, SAFs, and zones.

.SHORT TERM...(This evening through Thursday night)
Issued at 245 PM EDT WED MAY 6 2026

Shower activity has diminished some across the area as expected in
previous discussions. The cold front has slowly progressed southeast
and is now intersecting the CWA from southwest to northeast. At 18Z,
temperatures are generally in the low to mid 50s behind the cold
front and low to mid 60s ahead of it, in an area bordering
Virginia. Heading into the evening another wave of energy form the
southwest is expected to ride the frontal boundary into the area,
which could lead to another round of showers later this afternoon in
to the evening.

Areas of fog can be expected after midnight. As the shower activity
slowly sags southeastward and tapers off over the southeastern high
terrain by around noon on Thursday with overcast skies yielding to a
mix of sun and clouds. Temperatures will be cooler than recent days,
only reaching the low 60s northwest to upper 60s southeast for
Thursday`s highs before dipping back into the upper 30s in the
colder valleys, and low 40s along ridge tops. Main stem river
valleys may see patchy areas of fog redevelop. There may also be
patchy areas of frost in the coldest sheltered areas.

.LONG TERM...(Friday through Wednesday)
Issued at 431 PM EDT WED MAY 6 2026

An upper level low over Hudson Bay and its associated cyclonic
flow will allow for mean troughiness for most locations east of
the Rockies through the weekend. The low will then generally
migrate eastward into early next week, with northwest flow aloft
being reinforced across the northern half of the CONUS, although
model details remain more uncertain. This will result in periodic
rain chances across eastern Kentucky, with temperatures moderating
back to above normal this weekend, and then cooling off to below
normal into early next week.

High pressure will start off positioned across the southern
Appalachians early Friday. This feature will quickly move east,
allowing for return flow across eastern Kentucky. Temperatures
will rebound into the upper 60s to lower 70s. A short wave trough
and surface cold front will take aim at the Ohio Valley Friday
night, with our eastern valleys dropping off into the upper 40s
early on, before thicker clouds invade after midnight. Other
locations will remain in the 50s. Rain chances will increase from
the northwest after midnight, mainly north of the Mountain
Parkway. Better upper level support will remain to our north,
generally exiting by Saturday. The cold front will move through
eastern Kentucky on Saturday, supporting small chance PoPs.

Another brief period of drier weather moves in for Saturday
night, before better chance PoPs return Sunday into early Monday,
although the GFS and ECMWF remain at odds with the details.
Depending on the solution, rainfall totals could range from around
a tenth of an inch to as much as a half inch. High pressure and
dry weather take hold from Monday night through Tuesday
afternoon, before yet another system approaches our area from the
northwest, bringing the next chance of rain, mainly Tuesday night
into early Wednesday.

Highs will warm through the 70s by Sunday, before retreating to
the 60s on Monday. Temperatures will then warm back to near normal
readings by Wednesday, with highs in the mid to upper 70s. Lows
will be in the 40s and 50s, with Tuesday morning likely the
coolest day, with a few locations dipping to below the 40 degree
mark perhaps.

.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
ISSUED AT 810 PM EDT WED MAY 6 2026

At 00Z TAF issuance, shower activity remains through the
southeast portion of the forecast area but is trending more
southeast in time. With this pcpn, MVFR to IFR ceilings and
visibilities are prevalent and will likely stay that way through
the rest of the night. Conditions will then improve rapidly after
14Z, at most locations, into the VFR category. Winds are
generally under 5 knots from the northwest - becoming light and
variable tonight and staying that way on Thursday. There could
also be periods of patchy fog overnight - generally after 06Z.
