WTHR Issues Overnight Winter Weather Alert: What Central Indiana Needs to Know Before Monday Commute

Central Indiana drivers should brace for a slippery start to the week as WTHR’s Live Doppler 13 team issues a Weather Impact Alert for late-Sunday night through Monday morning. Meteorologist Robb Ellis warns that a fast-moving band of snow and freezing drizzle will overspread the region after midnight, dropping 1–3 inches of accumulation on Indianapolis, Carmel, Fishers, Greenwood, and surrounding suburbs before tapering off by mid-morning. Road temperatures are already below freezing, so even light precipitation will quickly turn untreated highways slick. INDOT crews plan to pretreat major interstates, but secondary roads and neighborhood streets could remain icy until midday. Commuters should allow extra time, reduce speed, and keep at least a five-car buffer when following other vehicles. Key timing • 12 a.m.–3 a.m.: Snow develops northwest of Lafayette and pushes southeast. • 3 a.m.–7 a.m.: Heaviest burst crosses I-65 corridor; visibility may drop below ½ mile. • 7 a.m.–10 a.m.: Precipitation transitions to spotty flurries; black ice lingers during rush hour. Potential school closings and delays Districts in Boone, Hamilton, Hendricks, Marion, and Johnson counties are monitoring conditions. Parents can check WTHR’s real-time closings page or sign up for push alerts in the 13News app to stay informed overnight. Air travel impacts Indianapolis International Airport advises passengers on early flights to verify departure times and consider arriving 30 minutes earlier than usual for de-icing operations. When will roads improve? Temperatures rebound to 34° by noon with partial sunshine, helping main arteries clear. A refreeze is possible Monday night as readings slide back into the 20s, so evening commuters should remain cautious. What’s next in the forecast? A second, weaker clipper could brush the Ohio River Valley late Tuesday, but current model guidance keeps additional snow totals under ½ inch. The pattern turns milder by Thursday with highs climbing into the lower 50s and plenty of March sunshine.
