KEY MESSAGES

* A cold front from near Bowling Green to the southern Bluegrass will continue dropping south. Isolated to widely scattered afternoon/evening showers and thunderstorms will remain possible south of the front.

* Temperatures in the mid to upper 80s will increase to the low 90s by Sunday and the mid 90s for next week.

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.
