.SHORT TERM /THROUGH FRIDAY/...
Issued at 400 PM EDT Thu Aug 27 2026
A cold front is currently bisecting the CWA, stretching from the
Bowling Green area northeast through the southern Bluegrass.
Isolated to scattered showers and thunderstorms will remain possible
southeast of the front towards the Lake Cumberland area into eastern
Kentucky. MLCAPE values reach to near 1,500 J/kg in the area with
moderate lapse rates and weak shear. None of this activity is
expected to produce anything severe before fading tonight. North of
the front, light northerly winds and high pressure are expected to
keep the area dry under continued afternoon cumulus as temperatures
climb into the mid to upper 80s.
Tonight, winds are expected to ease as skies clear. This will lead
to some light patchy fog as the cold front pushes off to the south of
the CWA.
Friday, the upper trough over the eastern US will begin lifting
north as the ridge to the west expands eastward towards the East
Coast. Surface high pressure centered to our northwest will keep
north-northeast winds over southern Indiana and central Kentucky.
Temperatures will climb into the mid 80s.
&&
.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
Issued at 400 PM EDT Thu Aug 27 2026
By Saturday, the upper ridge will cover the southern two-thirds of
the CONUS with the center of the upper high near New Mexico and the
Texas Panhandle. This will keep CAA in the Lower Ohio Valley until
Sunday. Highs will be limited to the mid to upper 80s.
Sunday, the upper high gets pushed farther east over the Ozarks and
northern Texas. The surface high moves east of Kentucky with a low
approaching from the Plains, resulting in WAA returning. We remain
dry as temperatures increase into the low 90s.
For the rest of the week, the upper ridge slides until directly over
the Ohio Valley with surface high pressure parked over the
Southeast. Continued WAA and mostly clear skies will help
temperatures climb into the mid 90s with dew points in the mid to
upper 60s.

.AVIATION /18Z TAFS THROUGH 00Z SATURDAY/...
Issued at 400 PM EDT Thu Aug 27 2026
High pressure behind a cold front, dropping south through central
Kentucky, will keep the TAF sites dry under scattered to broken
cumulus. Light winds will begin veering towards the north this
evening. Clearing skies and calm winds is expected to cause MVFR to
VFR fog at HNB, BWG, and RGA.
