757 AM EDT Thu Apr 23 2026
.KEY MESSAGES...
- Warm and dry weather is expected into the day Friday.
- Widespread showers and thunderstorms enter the forecast on
Friday night into Saturday and again early next week.
&&
.SHORT TERM...(Today through Friday)
Issued at 756 AM EDT THU APR 23 2026
Ridging aloft is moving in from the west today while surface
ridging reside over the southeast CONUS. This will result in warm
and dry weather today and tonight, with low level moisture
remaining limited by flow coming out of the ridge.
Meanwhile, an upper level trough currently extends southward over
the western CONUS. A deep upper low will develop over southern
Saskatchewan in the heart of the trough and strengthen it. A
wave/vorticity lobe rotating around the low/trough will ripple
into our ridging aloft and weaken it temporarily by late Friday,
which will also bring a weak cold front toward KY from the
northwest. As this is happening, the surface ridging will also
begin to give way and a bit more moisture should be able to
advect into the area. All this in combination should lead to
showers/thunderstorms approaching or arriving from the west late
in the day. However, the highest probability holds off until
Friday night in the long term period.
.LONG TERM...(Friday night through Wednesday)
Issued at 756 AM EDT THU APR 23 2026
A series of shortwaves break down ridging over the Ohio Valley
Friday night. Showers and storms will precede a frontal passage
potentially leading to meaningful area wide rainfall Friday night
through Saturday. Sunday generally remains quiet, with a mix of
sun and clouds. An area of low pressure will progress from the
Central Plains into the Mid Mississippi Valley on Monday. The
system`s warm front stretching from the Central Plains into the
Lower Mississippi Valley will lift north with the low, into the
Tennessee and Ohio valleys. While some showers will accompany the
warm front, showers and storms will precede the systems cold
front, sweeping across Kentucky west to east through the evening
and overnight on Monday. The evolution of the frontal passage in
respect to a potential 45-60 knot LLJ is worth watching. This
could be the area`s second crack at needed area wide rainfall. A
series of weaker frontal passages could lead to scattered shower
and storm chances Wednesday and Thursday.
Temperatures generally range from the upper 70s to low 80s through
the extended period, with lows generally remaining in the 50s.

ISSUED AT 756 AM EDT THU APR 23 2026
Valley fog bringing IFR or worse conditions is present near the
WV border, but should dissipate by around mid morning. It is not
expected to affect TAF sites. Otherwise, VFR conditions will
prevail through the period.
