Louisville, Kentucky – A developing winter weather system is expected to move across the Ohio Valley Tuesday into Tuesday night, bringing a mix of rain and snow to parts of Kentucky and southern Indiana and potentially affecting travel along major corridors 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 creates uncertainty in precipitation type, especially across southern Indiana and north-central Kentucky, where the boundary between rain and snow is expected to fluctuate.
Forecasters indicate that southern Kentucky is more likely to see mainly rain, while areas farther north that remain north of the warm front will have a higher chance of snow. In locations that experience several hours of snowfall, light snow accumulations of a few inches will be possible. Areas closer to the rain-snow transition zone may see little or no accumulation.
Before the main system arrives, spotty flurries or light snow may occur late tonight into Monday morning, though significant impacts are not expected from this initial activity.
The National Weather Service notes that forecast confidence is medium, with the greatest uncertainty focused on precipitation type and placement. Even small shifts in the storm track could change which communities see rain versus snow.
Travel impacts may increase Tuesday evening and overnight, particularly along I-64 between Louisville and southern Indiana, as well as along 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 encouraged to monitor forecast updates closely as the system approaches. Motorists should be prepared for changing road conditions and allow extra travel time Tuesday night.
While this does not appear to be a major winter storm at this time, forecasters stress that light accumulations combined with cold temperatures can still create hazardous travel, especially during evening and overnight hours.
