Indianapolis woke up early Wednesday, March 18, 2026, to a surprise coating of light snow and temperatures in the mid-20s, leaving a few slick spots on bridges and untreated side streets. The snow arrived in patchy bands, so most neighborhoods picked up only a quick dusting rather than a long-lasting storm.
Morning Commute, Minor Slick Spots
A Special Weather Statement remains in effect as light snow lingers through the morning commute, with the potential for slick spots on bridges, overpasses and untreated surfaces. New accumulation is expected to stay under about a half inch, but brief, steadier bursts could knock visibility down in spots. Drivers are urged to slow down, give themselves extra time and be ready for changing conditions. The National Weather Service Indianapolis issued the advisory early Wednesday.
Timing And Temperatures
Forecast guidance keeps the best chance for light snow in place through midmorning, with activity winding down by around 2 p.m. After that, skies should gradually clear and temperatures are expected to climb into the upper 40s. The afternoon warmup will help dry out most roads, although a few untreated spots could hold onto slick patches through mid-morning.
Afternoon Winds And Late-Week Warmup
Southerly winds are set to pick up to around 8 to 12 mph, with gusts near 20 to 21 mph, pulling milder air into central Indiana. Highs should reach near 48°F Wednesday, rise to around 59°F Thursday with a chance of light rain, then jump to near 70°F by Friday. A sunnier and warmer weekend is on tap, with highs in the low 70s as the mild pattern settles in. The National Weather Service Indianapolis will have the latest timing and any forecast tweaks.
What To Watch
For most residents this is shaping up as a quick, commute-time nuisance rather than a disruptive winter event, but it is still worth treating the morning drive with caution. Watch for isolated slick spots, check local road reports, and give yourself extra travel time if visibility drops or if untreated ramps turn icy.
