Kentucky – A cold, still start is gripping Louisville, where temperatures hovering near 39°F are allowing frost to form on rooftops, lawns, and windshields early today. The air feels crisp and quiet, but the impact is immediate for gardeners and early commuters.
According to the National Weather Service, a Frost Advisory remains in effect until 9 a.m., with temperatures dipping into the upper 30s across Jefferson County and surrounding areas. Calm winds and clear skies are creating ideal conditions for frost development, especially in low-lying neighborhoods.
Drivers along I-64, I-65, and local bridges should stay alert through mid-morning. While widespread ice is not expected, isolated slick spots can form where moisture lingers. This is the time of year when brief “flash freezing” can catch drivers off guard, particularly on elevated surfaces.
Through the afternoon, sunshine takes over and temperatures rebound to near 65°F. That warming trend continues steadily. Tuesday brings highs near 55°F under mostly sunny skies, followed by a stronger jump to 72°F by Wednesday as winds shift and pull in warmer air.
By Thursday and Friday, Louisville enters a true spring pattern. Highs climb into the low to mid-70s, with a slight chance of showers and thunderstorms developing late Friday. Roads may turn briefly slick during any passing showers, but widespread impacts remain limited for now.
For now, the priority is the early frost window. Protect sensitive plants and allow extra time if heading out early. Warmer days are quickly returning. How cold did it feel in your neighborhood this morning?
