KEY MESSAGES

- The possibility of showers and thunderstorms will persist during the next week, with the greatest coverage for the area as a whole on Friday-Saturday and Tuesday-Wednesday. - Isolated heavy rainfall may occur where thunderstorms are most persistent today through Saturday.

LONG TERM

(After midnight Friday night through Wednesday) Issued at 810 AM EDT THU AUG 6 2026

A lobe rotating around a large upper low over Hudson Bay will extend a trough southward over the Ohio Valley at the start of the period. This will reach southward into a col between upper highs over the southwest CONUS and off the southeast coast. This weakness in the subtropical ridging will allow for at least scattered showers/thunderstorms for our area as we move into the weekend. The troughing retreats northward by Sunday and rising geopotential heights should result in less convection through Monday. A series of shortwave troughs then nudge the prevailing westerlies aloft southward again by mid week and give us slightly increased west northwest flow aloft. This regime gives an increased potential for showers/thunderstorms with a risk of MCS occurrence Tuesday-Wednesday.

AVIATION

(For the 12Z TAFS through 12Z Friday morning) ISSUED AT 751 AM EDT THU AUG 6 2026

Fog was present in many valleys early this morning, especially in southeast KY, and was resulting in IFR or worse conditions where it was prevalent. The fog will dissipate during the morning, giving way to VFR conditions. Scattered thunderstorms will develop in the afternoon and persist into the evening, bringing localized sub-VFR conditions. Most of the precipitation should die out in the evening, but valley fog should develop to some extent once again during the night. The fog's extent is uncertain, and may be more restricted if there is more cloud cover as compared to the preceding night.
