.UPDATE...
Issued at 1215 PM EDT THU MAY 28 2026

As a cold front continues to sag south across the north, drier
air is filtering in from the north. A few low clouds and
stratocumulus linger south of I-64 with these gradually mixing
out. The drier air will continue to filter in through the
afternoon with drier weather compared to recent days.

&&

.SHORT TERM...(today through Friday)
Issued at 716 AM EDT THU MAY 28 2026

A cold front is dropping south of the area early this morning,
allowing drier air to arrive from the north. With weak low level
flow and a lack of mixing last night, the drier air initially
began to over ride lingering moist air at the surface over eastern
KY. The resulting radiational cooling allowed for low clouds and
fog to develop, especially north of KJKL. Strong sun at this time
of year will eventually lead to warming to mix away the lingering
low level moisture today, but exactly how quickly it happens this
morning is a little uncertain. Once skies become mostly clear, it
will last at least through tonight. Light winds and the arrival
of drier air will result in cooler lows on Friday morning, with
some of our coldest locations possibly dipping below 50.

The upper trough supporting the cold front is over the northeast
CONUS and is retreating in that direction, which will cause the
front to lose momentum and stall in the vicinity of TN. As the
northeast trough retreats, it will also allow narrow upper level
ridging and an adjacent weak trough on its southwest side to
shift toward us from the southwest. With this, mid-upper level
moisture overriding the front will advance toward us from the
southwest and result in increasing clouds on Friday, mainly over
the Cumberland drainage basin.

.LONG TERM...(Friday night through Wednesday)
Issued at 716 AM EDT THU MAY 28 2026

The forecast period begins with a surface low moving through the
Deep South and gradually lifting north into the Tennessee Valley. As
this feature ejects eastward, the associated warm front will lift
north into the JKL CWA, bringing increased shower and thunderstorm
activity primarily to the Cumberland River Basin. Concurrently,
another surface low is forecast to dive out of southern Canada into
New England. As this occurs, an associated, mostly dry cold front
will drop south through the Mid-Atlantic and Ohio Valley Friday
overnight into Saturday morning. This combination of surface
boundaries will bring showers and storms first Friday night along
the warm front. As the cold front drops south, additional showers
and thunderstorms will be possible across the southeastern portion
of the area before post-frontal surface high pressure builds into
the region for the weekend.

Surface high pressure will remain in place through the weekend,
bringing pleasant temperatures. However, the region will remain on
the western periphery of a large, stagnant upper-level trough that
is forecast to settle over the eastern United States. Within this
troughing pattern, the first surface low will exit the area early
Saturday, but a second low is forecast to dive southeast toward the
Great Lakes and Ohio Valley by Monday. This feature will drag
another cold front through the area late Sunday into Monday. Showers
and storms will once again be possible, though mainly confined to
the Cumberland River Basin. This trough is forecast to slowly shift
eastward Tuesday into Wednesday. Persistent northerly flow will keep
temperatures pleasant through the middle of next week, but by
Thursday, winds will shift to the southwest, allowing warmer
temperatures to build back into the region.

Overall, the forecast period will remain somewhat active,
particularly for the southern portions of the CWA where a series of
frontal boundaries will provide sufficient lift for showers and
storms. The area dries out for the weekend, where near-seasonal
temperatures are expected. Another system brings precipitation
chances on Monday, followed by a return to dry conditions toward the
middle of next week.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
ISSUED AT 134 PM EDT THU MAY 28 2026

As of issuance time, a cold front continues to sag south and was
nearing the TN border with VFR reported across the region at
issuance time. High pressure will build across the Great Lakes and
sections of the OH Valley to the Central Appalachians through the
period. Mainly VFR is anticipated though valley fog is anticipated
between about 04Z and 13Z with reductions to IFR or lower anticipated.
The TAF sites are not expected to be affected by the fog. Winds
will remain between north and east at less than 10KT.
