Indiana wakes to glowing headlights and vanishing taillights as dense fog grips central portions of the state this Christmas morning.
Visibility has dropped to one-quarter mile or less, prompting a Dense Fog Advisory until 11 a.m. EST, according to the National Weather Service in Indianapolis. The fog is already slowing travel across Indianapolis and surrounding counties, especially on early holiday drives.
Moist air, calm winds, and saturated ground are keeping fog locked in place through the morning commute. Drivers may notice damp pavement, blurred intersections, and sudden visibility changes, particularly on secondary roads and near open fields.
Temperatures hover in the lower 50s this morning and remain mild into the afternoon. Patchy drizzle may develop late, keeping road surfaces slick even after fog thins. For now, conditions improve gradually toward midday, but caution remains essential.
Looking ahead, post-Christmas travel faces new challenges. Rain chances rise Friday, with precipitation likely during the day. Highs push into the mid-60s before a gradual cooling trend begins. Wet roads and pockets of fog may redevelop, especially during evening travel.
By the weekend, clouds linger and temperatures begin to slip. Forecast models show a warm-to-cold transition developing late Sunday into Monday. While widespread snow is not confirmed for central Indiana, colder air moving in during the final days of December raises early winter awareness.
Nationally, meteorologists are tracking heavier snow across the Great Lakes and Northeast, along with icy mixes east of Michigan. These systems may influence colder air spilling south early next week.
Plan extra time for Christmas morning drives. Keep headlights on, slow down, and allow space between vehicles. As December travel continues, expect changing conditions and stay alert for updated Indiana Weather Alerts.
