SHORT TERM /THROUGH SATURDAY/

Issued at 334 PM EDT Thu Sep 24 2026

Today's clouds are still struggling to clear out. Occasional breaks are occurring and the layer is thinning according to PIREPs, but complete clearing is unlikely until around tomorrow afternoon. We should maintain light easterly surface winds across the CWA as we sit on the backend of a strong UL trough. We also sit in a small surface shortwave that tries to push through but gets stagnated by the nor'easter in the Atlantic. Overnight pushes us into a northeasterly flow pattern, again mixing in more dry air, which will prevent fog/drizzle/precip but we should steadily erode the cloud deck. Overnight lows are expected to remain temperate in the upper 40s to mid 50s.

As we continue that northeasterly flow into tomorrow, we are expecting to finish mixing out the clouds with drier air. Skies should be mostly clear tomorrow during the day, allowing us to heat up to the low-mid 70s across southern Indiana and the Bluegrass region band the upper 70s across Central and South Central KY. Friday evening, expect mid-level clouds across the CWA. This should prevent radiational cooling, keeping our lows around 50-55. Again, dry air, so no precip/fog expected. We likely clear the clouds out into Saturday, we should hit the mid-upper 70s again with a light northerly wind.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/

Issued at 334 PM EDT Thu Sep 24 2026

Sunday through Thursday...

Sunday should remain mostly clear and we begin to warm up again, with highs in the mid to upper 70s and dew points in the low 50s. Certainly a pleasant day across the CWA, with light winds out of the North keeping us with relatively low-humidity. Overnight brings some scattered clouds and lows in the low 50s along with keeping our northerly winds.

Monday keeps the northerly winds, and the whole CWA sees highs in the upper 70s. This could certainly increase and see a high in the low 80s if we keep clear skies throughout the day. Monday night brings lows in the low to mid 50s again.

Tuesday sees a certain return to the low-80s (S IN, Bluegrass) to mid-80s (Bowling Green area). We swap to an easterly wind, so expect a smidge more humidity throughout the day and night. Overnight lows expected aroung the low-mid 60s.

Wednesday brings a surface Low centered over southern IL attached to a very deep UL trough in the Great Plains. This pushes a strong cold front across the area later in the evening and our first chance at measurable precip in a week or so. We should top out with highs in the low-mid 80s again in the afternoon; wind should switch behind an advancing cold front to southerly and be stronger throughout the evening hours, with gusts in the 20-knot mark. Cloudy and rainy overnight Wednesday with lows in the mid to upper 60s.

AVIATION /00Z TAFS THROUGH 06Z SATURDAY/

Issued at 717 PM EDT Thu Sep 24 2026

We'll continue to see gradual improvements to the cigs through the period, with mostly VFR expected. There may be one last round of patchy DZ this evening, but overall conditions will be improving. Drier air will filter into the region by tomorrow, ending the low stratus that has been blanketing the region the last few days. More sunshine is expected tomorrow, with SCT high level clouds and light winds from the northeast.
