Louisville, Kentucky — A developing winter weather system is expected to move through the Ohio Valley Tuesday into Tuesday night, bringing a mix of rain and snow to parts of Kentucky and southern Indiana. The system could impact travel along major routes, including Interstate 64, Interstate 65, and Interstate 71.
According to the National Weather Service in Louisville, a low-pressure system will cross the region Tuesday, with a warm front lifting northward ahead of it. This setup is creating uncertainty in precipitation types, particularly across southern Indiana and north-central Kentucky, where the rain-snow line may shift throughout the day.
Forecasters say southern Kentucky is more likely to see mainly rain, while areas farther north that remain on the colder side of the system will have a higher chance of snow. Locations that experience several hours of snowfall could see light accumulations of a few inches, while areas closer to the transition zone may see little to no accumulation.
Ahead of the main system, spotty flurries or light snow are possible late tonight into Monday morning, though no significant impacts are expected from this early activity.
Forecast confidence remains medium, with the greatest uncertainty centered on precipitation type and placement. Meteorologists note that even small changes in the storm’s track could significantly alter which communities see rain versus snow.
Travel impacts may increase Tuesday evening and overnight, especially along I-64 between Louisville and southern Indiana, as well as I-65 and I-71. Roads could become slick in areas where snow develops or where rain changes to snow late in the event.
Residents are urged to monitor forecast updates closely as the system approaches. Drivers should prepare for changing road conditions, reduce speeds, and allow extra travel time Tuesday night.
While this system is not expected to be a major winter storm, forecasters caution that even light snow combined with cold temperatures can create hazardous travel conditions, particularly during evening and overnight hours.
