DISCUSSION

The cold front is now sitting over central Kentucky as it continues to the southeast. Winds are fairly light ahead of the front with 5 to 10 mph winds generally out of the north behind it. This is dropping temperatures into the mid to upper 60s across southern Indiana and near the Ohio River in central Kentucky. The earlier low level jet has moved out of the area to the northeast as 2 inch peak precipitable water values along the front are beginning to drop off and retreat to the south. This trend is expected to continue through the evening, reducing rainfall rates over central Kentucky.

Tonight, the heaviest rain will stay closer to the higher moisture, precipitable water values in the 1.8 to 2 inch range, and slide east across southern Kentucky. Areas farther to the north will see lighter more scattered showers. Most of the rain will move off to the east by sunrise Saturday morning with lows in the low 50s in southern Indiana to low to mid 60s in far southern Kentucky.

Through the day Saturday, a few isolated showers are expected to drift northeast through the Lake Cumberland area, but all other areas in the CWA are expected to remain dry with mostly sunny skies expected over the northern two thirds of the CWA. Surface high pressure centered over the Great Lakes will keep east-northeast winds in place as most places see the low to mid 70s for highs. There will likely be a few places that only see the upper 60s towards eastern Kentucky.

Saturday night, clear skies, light winds, and moisture from today will likely lead to patchy fog as radiative cooling drops temperatures towards dew points.

Sunday, stubborn cloud cover is expected to remain along and south of the parkways during the day, but as we head into the overnight period, a dry cold front will get pushed southeast towards the Lower Ohio Valley by northwest upper flow. This will clear skies and bring another round of light CAA ahead of another surface high behind the front, keeping highs in the upper 60s to mid 70s for Monday and Tuesday. Monday and Tuesday night, some low temperatures could drop into the upper 30s to low 40s before the high pushes east through the Great Lakes, returning WAA. Highs get lifted into the upper 70s to low 80s on Wednesday before inching slightly warmer for the end of the workweek.

AVIATION /18Z TAFS THROUGH 00Z SUNDAY/

Issued at 201 PM EDT Fri Oct 2 2026

As a cold front slowly moves southeast across central Kentucky rain showers will continue to impact area TAF sites. Winds across southern Indiana and far north central Kentucky are already out of the north behind the front. LEX, RGA, and BWG will see their wind shift towards the north as the front passes. Periods of heavier rainfall are dropping visibilities into MVFR ranges, but the greater impacts will come from IFR ceilings expected at all TAF sites.
