KEY MESSAGES

- There is a potential for showers/thunderstorms over south central and southeast Kentucky at times through Monday. Otherwise, drier weather overall will last through the next week.

LONG TERM

(Friday night through Wednesday) Issued at 716 AM EDT THU MAY 28 2026

The forecast period begins with a surface low moving through the Deep South and gradually lifting north into the Tennessee Valley. As this feature ejects eastward, the associated warm front will lift north into the JKL CWA, bringing increased shower and thunderstorm activity primarily to the Cumberland River Basin. Concurrently, another surface low is forecast to dive out of southern Canada into New England. As this occurs, an associated, mostly dry cold front will drop south through the Mid-Atlantic and Ohio Valley Friday overnight into Saturday morning. This combination of surface boundaries will bring showers and storms first Friday night along the warm front. As the cold front drops south, additional showers and thunderstorms will be possible across the southeastern portion of the area before post-frontal surface high pressure builds into the region for the weekend.

Surface high pressure will remain in place through the weekend, bringing pleasant temperatures. However, the region will remain on the western periphery of a large, stagnant upper-level trough that is forecast to settle over the eastern United States. Within this troughing pattern, the first surface low will exit the area early Saturday, but a second low is forecast to dive southeast toward the Great Lakes and Ohio Valley by Monday. This feature will drag another cold front through the area late Sunday into Monday. Showers and storms will once again be possible, though mainly confined to the Cumberland River Basin. This trough is forecast to slowly shift eastward Tuesday into Wednesday. Persistent northerly flow will keep temperatures pleasant through the middle of next week, but by Thursday, winds will shift to the southwest, allowing warmer temperatures to build back into the region.

Overall, the forecast period will remain somewhat active, particularly for the southern portions of the CWA where a series of frontal boundaries will provide sufficient lift for showers and storms. The area dries out for the weekend, where near-seasonal temperatures are expected. Another system brings precipitation chances on Monday, followed by a return to dry conditions toward the middle of next week.

AVIATION

(For the 12Z TAFS through 12Z Friday morning) ISSUED AT 802 AM EDT THU MAY 28 2026

Conditions varied widely at the start of the period, from VLIFR to VFR. The best conditions were generally outside of valleys near the TN border, with most other locations being very poor. The fog and low clouds will lift and dissipate during the morning, with all areas looking for a return to VFR conditions early this afternoon and then lasting into tonight. Fog should develop in many valleys again late tonight, but is not forecast to affect TAF sites.
