Indianapolis, Indiana – Drivers across central Indiana could encounter slick, snow-covered roads within hours as light snow begins after midnight and lingers into the Wednesday morning commute, creating hazardous travel on major corridors like I-65 and I-70 before sunrise.
According to the National Weather Service in Indianapolis, a widespread band of light snow will move in late Tuesday night and persist through early Wednesday, with most areas picking up around 0.5 inches and isolated pockets reaching up to 1.0 inch. The timing aligns directly with peak commute hours, increasing the risk of reduced traction and slower travel speeds.
Road conditions are expected to deteriorate quickly, especially on untreated surfaces, bridges, and overpasses. Indianapolis metro routes including I-465 and U.S. 31 may see patchy snow cover by 5 a.m., while surrounding counties from Lafayette to Bloomington face similar impacts. Northwest winds and temperatures stuck in the 20s will prevent melting during the morning drive.
Drivers should allow extra travel time, reduce speeds, and keep headlights on during low visibility. INDOT crews may treat primary roads overnight, but secondary streets could remain snow-covered into mid-morning.
Conditions improve later Wednesday as snowfall tapers off, but another round of advisories remains possible if temperatures stay below freezing into early Thursday.
