Morning frost glimmers across parked cars in Louisville today as Kentucky settles into another brisk December stretch. The air feels calm now, but meteorologists warn that a late-week pattern shift will bring colder air, scattered showers, and even a few snowflakes before the weekend arrives.
According to the National Weather Service in Louisville, clouds will build midweek ahead of a developing low-pressure system. Showers become likely by Wednesday, with gusty south winds pushing temperatures near 47°F. By Thursday, the same system begins to cool — turning lingering rain into a brief mix of sleet or snow as colder air filters in from the northwest.
Highs will tumble from the mid-40s Thursday to the upper 30s Friday, then dip into the 20s by Friday night. Any wet pavement could refreeze early Saturday, creating slick conditions on bridges and overpasses. Motorists traveling along I-64 or I-65 should use caution through the weekend, especially during early morning commutes when temperatures fall below freezing.
Looking ahead, forecasters expect mostly cloudy skies through Sunday with highs near 35°F — a sharp reminder that winter’s grip is tightening. Long-range models also show colder air spreading across the Ohio Valley between December 11–17, potentially setting up more widespread snow chances for the region.
