Frost is rapidly developing across eastern Kentucky's valleys early Monday, with temperatures dropping into the low 30s and creating immediate risks for plants and early morning travel. According to the National Weather Service in Jackson, a Frost Advisory remains in effect until 10 a.m. Monday across much of east-central and southeastern Kentucky.

Why it matters

Frost can severely damage or kill sensitive plants, especially in low-lying valley areas where the coldest air settles. Drivers may also encounter slick road conditions during the early morning commute.

The details

The coldest conditions are settling in valleys, where temperatures are bottoming out near 32°F around sunrise, allowing widespread frost formation. Communities including Hazard, Pikeville, Somerset, and London are seeing frost accumulate on lawns, vehicles, and elevated surfaces. In valley-prone areas of Perry, Letcher, and Harlan counties, colder air is pooling, increasing the likelihood of heavier frost coverage.

• A Frost Advisory remains in effect until 10 a.m. Monday across much of east-central and southeastern Kentucky.
• Temperatures will rise after mid-morning, but additional cold alerts remain possible if clear skies persist into tonight.

What’s next

Residents should cover or bring in sensitive plants immediately, especially in low-lying areas where frost is most severe. Gardeners and growers across Pulaski, Laurel, and Whitley counties face the highest risk of plant damage if precautions aren't taken.
