LONG TERM
(Saturday through Thursday) Issued at 350 PM EDT THU MAY 28 2026
The extended period opens Saturday morning with an upper level low over the New England area. High pressure builds over the Upper Midwest in a quasi omega-block pattern.
A weak area of low pressure over the Southeast will feature a stationary front that creeps north into the Tennessee Valley later Friday. Isolated to scattered showers and thunderstorms are expected across southern Kentucky, mainly south of the Hal Rogers/KY Highway 80 corridor. These showers and storms will linger into Saturday morning before a dry cold front passes south from the New England upper low. This frontal passage will eventually cause showers and storms to tapper off across the area through the AM Saturday.
Some weak southerly flow brings moisture north into the area for Sunday. A second low is forecast to dive southeast toward the Great Lakes and Ohio Valley by Monday. A secondary cold front will move through the area later Sunday into Monday. Showers and thunderstorms will be possible mainly across the Cumberland River Basin. As the trough is forecast to pass east Tuesday into Wednesday, dry weather returns through the remainder of the extended period.
Temperatures remain mild through next Thursday, with highs and lows near normal overall (mid to upper 70s for highs, upper 50s for lows).
