Indiana drivers step into a gray, muffled morning as dense fog presses across central Indiana, reducing visibility and slowing early holiday travel.
According to the National Weather Service in Indianapolis, patchy to locally dense fog continues this morning, with visibility dropping to one-quarter mile in spots, especially near Interstate 70 and surrounding corridors. Moist air and light winds are allowing fog to linger longer than usual, keeping roads damp and sightlines short.
Fog remains the main concern today, but wet pavement and mild temperatures near the mid-30s add another layer of risk. Drivers may not see brake lights ahead until the last moment. Travel speeds may suddenly drop, especially on ramps and rural highways.
Meteorologists say visibility should gradually improve from north to south, though pockets of fog could redevelop during low-light periods later this week. For now, slow speeds and extra spacing remain critical for commuters and holiday travelers.
Looking ahead, rain chances increase late tonight into Thursday, with periods of light rain and lingering fog expected through Christmas Day. Highs climb into the mid-50s Wednesday and Thursday, continuing a mild December trend across Indiana and much of the Midwest.
By Friday and Saturday, temperatures remain unusually warm for the first week of winter, reaching the low 60s at times. However, repeated rain and drying cycles raise concern for slick roadways after sunset, especially if temperatures dip closer to freezing overnight later this weekend.
While no snow or ice is expected in the immediate window, winter travel risks are still present. Fog, wet pavement, and sudden visibility drops often cause more crashes than snow itself.
Plan extra travel time, use low-beam headlights in fog, and stay alert on interstates during post-Christmas trips.
