Marine Weather and Tide Forecast for Middles, KY

UPDATE
Issued at 956 AM EDT SAT JUN 27 2026

Thunderstorms with heavy rainfall are finally making a move into the JKL fcst area from the west, with a threat of flash flooding.
Have adjusted POPs for the latest radar trends, and also raised thunder potential where storms are moving in.

UPDATE Issued at 740 AM EDT SAT JUN 27 2026

No significant changes were made to the forecast with mainly just the inclusion of the latest obs and trends for the T/Td/Sky grids and the current radar and CAMs guidance for the near term PoP and thunder grids. These minor adjustments have been sent to the NDFD and web servers along with a freshening of the HWO, SAFS, and zones.

SHORT TERM
(Today through Sunday)
Issued at 500 AM EDT SAT JUN 27 2026

08Z sfc analysis shows low pressure nosing into the region, just north of the Ohio River, along its wavy front. This remains the focus for the development of organized clusters of showers and thunderstorms. The latest round of these are weakening as they exit eastern Kentucky, however, the next batch up are currently strengthening to the west over central Kentucky as evidenced by the cooling cloud tops on IR. For the most part the rains of Friday and last evening have primed a good portion of the area - especially along and north of I-64 (as captured by the Bath County mesonet site with nearly 3 inches of rain reported for the past 24 hours) for potential flood problems from any additional showers and storms arriving later this morning. Meanwhile, in this very humid environment, temperatures and dewpoints currently are running in the upper 60s to lower 70s, amid light and variable winds. In addition, there are areas of fog out there between the showers and storms.

The models, and their individual ensemble suites, remain in pretty good agreement aloft with the longwave pattern through the short term portion of the forecast. They all depict zonal mid-level flow taking on a northwesterly tilt by the end of the weekend as 5h ridging builds over the central Gulf Coast. This burgeoning ridge will be the source for a heat dome that envelops Kentucky and the region during the upcoming work week. For now, though, it will merely provide a glide path for additional impulses and minor waves - some convectively induced - to roll over the JKL CWA in the short term. The next wave up on this conveyor slides east through the state during the day before that northwest tilt brings another in from Indiana later tonight - departing south into Tennessee by midday Sunday. 5h height rises and overall subsidence then follows into Sunday evening. Given the good agreement among the models, the NBM was used as the starting point for the grids with little adjustment needed aside from CAMs guidance incorporated into the PoPs and QPF grids through Sunday morning.
Again, terrain details were limited considering the high moisture content.

Sensible weather features one round after another of convection lasting into the evening, at least, with likely some lulls in between lasting several hours. The rounds today will hit most of the area while those that linger tonight and into Sunday will favor the southern parts of eastern Kentucky. For this reason the Flash Flood Watch has been split up to remain in effect longer for the southern zones of our responsibility and even that may not be long enough judging by the 06Z HRRR run that continues to bring heavy rain to the Lake Cumberland area into the daylight hours of Sunday. High PW (near record) air in place will give any convection the potential for torrential rains and localized flash flooding until this air mass departs late in the weekend.
Temperatures will be warm both today and Sunday - though today's highs will be capped by the amount of clouds and convection around. In addition to the flood concerns, the organized nature to the storm clusters - especially those occurring near peak heating and instability - will also yield a threat mainly consisting of strong to damaging wind gusts primarily into this evening.

The main adjustments to the NBM starting point were to fine tune the PoPs and QPF per the latest consensus CAM guidance through Sunday. Did not need to adjust the temps or dewpoints for terrain or dry air mix down considering the high humidity air mass currently over the region.

LONG TERM
(Sunday night through Friday)
Issued at 115 AM EDT SAT JUN 27 2026

The long term period opens Sunday night with the area transitioning from a fairly active pattern, into a quiet yet hot one through next week. Analyzing modeled 500-mb heights, high pressure remains positioned over the Lower Mississippi River Valley, with the ridge axis extending further north, through the Upper Great Lakes and into Southern Ontario. Farther upstream to the west, a large scale trough positioned over the Intermountain West, features a few disturbances over the Northern Great Basin.

Across Eastern Kentucky, isolated to scattered storm activity may last through Sunday night through Monday afternoon, as a stationary front just north of the forecast area, retrogrades back west as a cold front from being on the lee side of the ridge axis. These generally remain under a 25% of occurrence, located in the Upper Cumberland or southern portions of the Kentucky River Basins. With high pressure juxtaposed near Kentucky, storm chances remain very isolated Tuesday and Wednesday Scattered to widespread storm chances return towards the end of the week (Thursday and beyond), with shortwaves modeled to eject out of the western trough towards the Ohio Valley. The return of active weather looks plausible heading into the nation's 250th anniversary of independence.

Temperatures will generally warm into the low to mid 90s during the afternoons and cool into the upper 60s to lower 70s at night through the extended period. Models depict dewpoints remaining elevated in the upper 60s to mid 70s next week, leading to hot and muggy conditions. Heat indices of 100-105F remain possible Monday trough Friday next week.

AVIATION
(For the 12Z TAFS through 12Z Sunday morning)
ISSUED AT 810 AM EDT SAT JUN 27 2026

At issuance time, another robust wave of convection is working into eastern Kentucky. As a result, a mix of aviation conditions were reported across the region at issuance time. Periods of MVFR/IFR reductions and the potential for thunder on station will continue to plague much of the area through the rest of the morning. Some tempo and PROB30 groups were used for this and additional rounds of convection should occur after 16Z, as well.
Overall, showers/thunderstorms will be a possibility throughout the period, but there remains rather low confidence in timing/location, especially from 16Z onward and this continues to preclude using more specificity than PROB30 in the TAFs. Away from any storms, winds will be light and variable through mid morning before picking up from the southwest at 5 to 10 kts into the afternoon.
