.SHORT TERM /THROUGH SUNDAY/... Issued at 415 PM EDT Sat Oct 11 2025
Behind a slow moving weak cold front dropping south through central Kentucky, a broken deck of cloud cover remains along and north of Interstate 64. This line of clouds is expected to dissipate with time in otherwise clear skies. With surface high pressure centered north of the Great Lakes, north-northeast to northeast winds over the CWA continue to be light.
Tonight, the positively tilted upper ridge stretching over the Ohio Valley will continue to keep skies clear as winds ease. Temperatures will fall into the low 40s to low 50s with Louisville expected to be the only spot remaining in the 50s.
Sunday, more of the same. The surface high gets pushed farther east just north of Maine as the upper ridge remains in place. Continued light cold air advection keeps highs in the 70s under clear skies.

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... Issued at 415 PM EDT Sat Oct 11 2025
To start the new week, very little changes in the overall pattern. The positively tilted upper ridge extending from an upper high over Texas remains in place over the CWA as the surface high near Maine drifts just east of New Brunswick. Light cold air advection keeps highs mostly in the mid to upper 70s on Monday before some low 80s begin entering some of our western counties. Lows inch slightly warmer into the mid 40s to mid 50s by Monday night.
On Tuesday, the upper ridge begins to expand, covering the Plains and pushing farther east over the Ohio Valley. At the same time, a new stacked low moves east across northern Ontario, bringing another dry cold front to southern Indiana and central Kentucky. As the center of the surface high, behind the front, moves east across Canada under the upper ridge, CAA keeps flowing into the CWA. Skies remain mostly clear.
By Thursday night into Friday, as the surface high passes off to the east, return flow begins to lift temperatures and moisture levels by the weekend. Rain shower chances begin increasing from the west ahead of the next frontal system. The GFS remains quicker bring the precipitation in on Saturday while the Euro waits until Sunday, but overall, they paint the same picture.

.AVIATION /00Z TAFS THROUGH 06Z MONDAY/... Issued at 741 PM EDT Sat Oct 11 2025
Mostly VFR conditions expected, with the exception of possible early morning fog at HNB, BWG, and RGA. SCT clouds near 6 kft over southern IN and northern KY are forecast to dissipate quickly late this evening. We`ll also have some SCT thin cirrus stream north over the I-75 corridor tonight. Fog development is lower confidence, but at least some MVFR fog looks possible at the three sites mentioned between 08-12Z Sunday. Otherwise, VFR likely with light NE winds.
