KEY MESSAGES

- Humid, wet weather persists into tonight.

- Rain should become less prevalent late in the week as drier air arrives from the north.

UPDATE

Issued at 1135 AM EDT WED MAY 27 2026

Showers are ongoing at this time across parts of central and northeastern KY near a slow moving frontal zone. More isolated showers have recently developed in the south. Hourly grids were freshened up based on radar and observation trends. Pending the degree of heating/instability a strong storm or two may affect the region this afternoon to early evening. However, the main concern is showers and storms training over an area leading to high water or localized flash flooding.

LONG TERM

(Friday through Wednesday) Issued at 215 PM EDT WED MAY 27 2026

At the onset of the long term period, high pressure begins to build into the Upper Great Lakes. As this occurs an upper level low descends out of Hudson Bay and progresses southeast into the New England region through Friday. This low is then expected to depart off into the north Atlantic sometime Saturday. With the influence of high pressure in the Upper Great Lakes, deep moisture along a stationary boundary across Tennessee could creep back northeast into the area. This could lead to isolated to scattered showers and thunderstorms across southern portions of the CWA Friday and Saturday. A weak cold front will also work its way south At current, best chances (10-30%) remain along and south of the Hal Rogers/KY Highway 80 corridor. Saturday, a cold front will also progress south with the passage of the trough. This front may stall along the KY-TN stateline which may lead to isolated showers along the stateline Sunday.

With little forcing to progress a stalled boundary over the Tennessee Valley and high pressure off to the northwest, isolated to scattered shower and storm chances (10-30%) will remain Monday through Wednesday next week, mainly along and south the Hal Rogers/KY Highway 80 corridor to the stateline.

Temperatures remain mild through next Wednesday, with highs and lows near normal overall (mid to upper 70s for highs, upper 50s for lows).

AVIATION

(For the 12Z TAFS through 12Z Thursday morning) ISSUED AT 917 AM EDT WED MAY 27 2026

A mix of mostly MVFR and VFR conditions were reported across the JKL forecast area at the start of the period. There were scattered showers on a slow increase near and northwest of a line from Somerset to West Liberty. The showers are forecast to continue increasing in coverage until early afternoon, with thunderstorms also becoming possible. Precip will continue in the area into the night. IFR or worse conditions will occur with the heavier showers/storms, but outside of this, mainly a VFR/MVFR mix should continue into the evening. A cold front will move through the area from north to south tonight. Precipitation will taper off behind the front, but conditions are forecast to worsen, lowering to IFR at TAF sites. However, confidence in this and its timing is meager.
