KEY MESSAGES

- Dry weather persists into next week, with clear skies, mild days, and chilly nights expected.

- Light, patchy frost may develop late tonight and again on Saturday and Sunday nights in sheltered valleys away from lakes, rivers, and larger creeks. Fog is more likely near those bodies of water.

UPDATE

Issued at 723 PM EDT FRI OCT 23 2026

With afternoon dew points dipping lower than was expected over the southwest portion of the forecast area, and models supporting continued somewhat drier low levels there overnight, have lowered tonight's forecast min temps there slightly.

LONG TERM

(Sunday through Friday) Issued at 157 PM EDT FRI OCT 23 2026

Amplified upper ridging over the Mississippi and Ohio River Valleys Sunday and Monday will gradually weaken and get shunted south and east of the area, opening eastern Kentucky to more westerly and/or west- southwesterly flow aloft mid to late next week. At the surface, high pressure will remain in control through much if not all of the period. A cold front may move into the Midwest and Great Lakes region by Wednesday and Thursday of next week, allowing for surface winds to increase out of the south to southwesterly, though wind speeds would remain light.

Sunny/clear skies and dry weather is expected through the period with mild days and cool, if not chilly, nights, with valley fog through the river valleys and patchy frost (at least for Sunday night and perhaps Monday night) in some sheltered valley locations removed from larger bodies of water. The one potential exception is around the middle of next week (i.e., Tuesday night through Wednesday) when most models depict a weakening shortwave crossing the area, bringing an increase in clouds. Such a scenario would likely bring warmer overnight lows and reduce ridge/valley splits in temperatures.

AVIATION

(For the 00Z TAFS through 00Z Saturday evening) ISSUED AT 723 PM EDT FRI OCT 23 2026

Fog will bring IFR or worse conditions in some valley locations overnight and early Saturday, mainly near lakes, rivers, and large streams. KSYM has been affected by MVFR conditions around dawn in recent days, and with slightly higher low level moisture in our northern counties compared to recent days, have included some impacts there. Otherwise, VFR conditions with clear skies and light winds will prevail during the period.

JKL WATCHES/WARNINGS/ADVISORIES

None.
