A pale layer of fog rolls across the Ohio River Valley this morning, clinging to bridges and open fields as temperatures hover near freezing. Motorists from Louisville to southern Indiana should prepare for patchy freezing fog and slick conditions through midday Thursday before light snow develops later tonight.
According to the National Weather Service in Louisville, freezing fog may lead to thin sheets of ice on untreated roads and elevated surfaces. Light snow is also expected late Thursday across south-central Kentucky, with accumulations generally under half an inch — just enough to coat rooftops and overpasses. Bridges and shaded areas could be especially slick during the evening commute.
Friday will stay cold but mostly clear, with highs near the upper 30s and a light north wind. The chill deepens overnight as lows dip into the low 20s, marking a true early-December cold snap. Weekend conditions turn bright and brisk — Saturday brings partial sunshine and highs near 40°F, followed by a cold, clear night in the 20s.
Meteorologists note early signs of a more active winter pattern building next week. Long-range models hint at lake-effect snow bands redeveloping around December 11–17 across the Great Lakes and Midwest, potentially impacting pre-holiday travel from Chicago to Detroit.
Plan extra travel time today, especially on I-65 and I-64 near Louisville where fog and light snow could reduce visibility. Keep winter kits in your car, and watch for icy patches on shaded roads.
