Kentucky starts the day under a gray veil as fog drifts across neighborhoods and headlights glow softly on damp streets. Visibility drops quickly in spots, especially near rivers and low-lying roads, slowing the morning pace.
According to the National Weather Service in Louisville, patchy fog develops early today before lifting mid-morning. Skies remain mostly cloudy, with afternoon temperatures climbing near 40 degrees. Winds stay calm, allowing moisture to linger on pavement longer than usual.
Across the Louisville metro, fog creates brief travel challenges on I-64, I-65, and local parkways. Drivers may encounter sudden visibility drops, especially near the Ohio River and shaded stretches. Slow down, use low beams, and allow extra stopping distance through mid-morning.
Conditions improve later today as fog thins and clouds break slightly. Tonight turns colder, with lows near the freezing mark. Any leftover moisture could refreeze, setting up isolated slick spots on bridges and sidewalks by early Saturday.
Saturday brings quieter winter weather. Clouds gradually decrease, and highs reach the low 40s. Roads stay dry through the day, making travel smoother. Saturday night clears further, allowing temperatures to fall into the mid-20s. Frost becomes likely by sunrise Sunday.
Sunday stays bright but cool. Sunshine helps highs recover near 41 degrees, though the morning starts crisp. Calm winds keep the chill noticeable for early errands or outdoor plans. By Sunday night, clouds return with lows near 30, keeping freeze concerns in play.
The first full week of 2026 trends warmer. Monday jumps into the low 50s with sunshine, easing winter stress briefly. Tuesday pushes close to 60 with clouds increasing and a small rain chance later, signaling a more active pattern ahead.
For now, timing matters. Watch for fog early today and frost this weekend. Dress in layers and plan extra travel time when visibility drops.
