KEY MESSAGES

- Expect a clearing trend to continue this evening, with much cooler and drier air spreading across the region tonight.

- Widespread frost and brief periods of near-freezing to sub- freezing temperatures are likely tonight into Sunday morning.

LONG TERM

(Monday through Saturday) Issued at 354 PM EDT SAT OCT 17 2026

The models are in good agreement for the long-term period. This comes as upper-level ridging builds toward the Ohio Valley. At the surface, we will remain under the control of passing surface high pressure systems for the period. The biggest impacts on the horizon for the week will be the possibility of frost Monday morning and again Monday night into Tuesday, confined primarily to the sheltered valleys. Outside of the frosty mornings to start the week, expect afternoon highs to moderate, climbing back toward the 70s as the period progresses.

AVIATION

(For the 00Z TAFS through 00Z Sunday evening) ISSUED AT 750 PM EDT SAT OCT 17 2026

Clear skies and VFR conditions were in place over eastern Kentucky at TAF issuance. High pressure will keep those clear skies along with light variable to northeasterly winds in place through the forecast period. It is worth noting that patchy fog formation is possible in the river valleys late tonight but should stay away from the TAF sites.
