KEY MESSAGES

- Humid, wet weather persists into tonight.

- Chances for showers and storms from Thursday into early next week should be generally confined to locations south of the Mountain Parkway.

UPDATE

Issued at 734 PM EDT WED MAY 27 2026

No major changes to the forecast except touching up the PoP grids based on the latest radar trends and cleaning the aviation grids ahead of the 00Z TAFS. Grids have been saved and sent.

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 00Z TAFS through 00Z Thursday evening) ISSUED AT 740 PM EDT WED MAY 27 2026

A combination of VFR and MVFR TAFs are in place across the area as showers and thunderstorms continue to develop along a stationary boundary to our north. These showers and storms will continue through the evening before sunset leads them to dissipate. Once convection wanes, antecedent moisture and clear skies will combine to allow for categorical low-end MVFR to IFR fog through much of the overnight into the early morning before the fog burns off around 13 to 14Z. Once the fog burns off, sites will return to VFR. Showers and storms are possible again Thursday but confidence in the location of these storms is low; therefore, was omitted from the TAF. Outside of convection, winds will be light and variable. Thunderstorms could bring gusty and erratic winds before moving away from the TAF location.
