Key Messages

* Highs in the low 70s with lows in the 40s and isolated 30s will continue through the weekend.

* Patchy dense valley fog is expected to form again tonight and into the morning hours, slowly becoming patchier and isolated heading towards and west of I-65.

* Stubborn ridging promotes a prolonged dry period with pleasant afternoons through at least early next week.

====== Dense River Valley Fog & Warm Afternoons =====

There is a mid to upper level low swinging through southern KY and can see the swirl on water vapor imagery. This is just bringing passing high level clouds in our SE. Light northeasterly flow is keeping temperatures mild in the upper 60s to low 70s across the area. Arguably, the most exciting thing to monitor would be dew points today and for the following days. This will determine how dry and comfortable each afternoon will feel, along with the chances of fog formation each morning as well. Relative humidity values are generally bottoming out in the low and mid 30s but will recover to near 100% overnight and into tomorrow morning.

Low temperatures tonight will reach the low to mid 40s and mid to upper 30s in our deepest, decoupled river valleys. Just as this morning, dense fog will likely form in river valleys in the east, becoming more patchy dense fog in valleys west of I-65. As we saw this morning, fog will dissipate by late morning, with the latest being near 10-11 AM EDT in eastern areas. Then by Wednesday afternoon, the locked in ridge pattern overhead will lock in sunny skies and generally light N-NE flow. As long as the deep low off the east coast and troughing over the western US continues, our pattern will remain the same.

We'll have to monitor the dew points tomorrow as well as this will alter fog chances for Thursday morning. Fog may become more prevalent by then, but this will be fine tuned between now and tomorrow night.

===== Stubborn Ridging and Next Potential Rain Chance =====

Aviation

Issued at 723 PM EDT Tue Oct 20 2026

VFR conditions are expected to continue through this TAF period. Light winds out of the northeast will continue before backing to the north Wednesday afternoon. Skies will remain clear through Wednesday. Fog will be possible in river valleys and patchy over southern Indiana.
