Indianapolis Weather Overview
Indianapolis sits in the middle of Indiana's flat central plain, where warm Gulf moisture collides with cold Canadian air masses. This collision zone makes the Indianapolis weather radar one of the most active in the Midwest — severe thunderstorms, tornadoes, ice storms, and flooding all show up across the radar map regularly throughout the year.
Spring and summer bring the worst severe weather to Indianapolis. Supercell thunderstorms fire along frontal boundaries from March through September, producing damaging winds, large hail, and tornadoes that you can track on the doppler weather radar as rotation signatures develop. Indiana has logged over 1,500 tornadoes since 1950, and several major outbreaks — including the devastating Palm Sunday event of 1965 — tore through central Indiana with catastrophic force. The flat terrain gives storms room to organize and accelerate before reaching the Indianapolis metro area.
Winter weather in Indianapolis demands close radar monitoring too. The city averages 25.9 inches of snow per year, and ice storms can shut down roads for days. The Blizzard of 1978 buried Indianapolis under 20 inches of snow with 55 mph wind gusts and wind chill values plunging to -51°F. January 2026 broke the single-day snowfall record with 9.1 inches. Indianapolis also averages 42-43 inches of rain annually with 13 extreme precipitation events per year, making flash flooding a persistent concern along Fall Creek and the White River corridor. Checking the Indianapolis weather radar before heading out is essential year-round.
Indianapolis Weather Risks & Safety
Severe Thunderstorm Risk
Severe thunderstorms roll through Indianapolis regularly, especially spring through early fall. Expect damaging winds above 58 mph, large hail, and dangerous lightning. The radar shows you each storm cell's position, movement, and intensity — so you can tell if one is headed your way. When a thunderstorm warning drops for Indianapolis, get indoors and away from windows until it passes.
Tornado Risk
Tornadoes hit Indianapolis hardest in spring and early summer, when warm Gulf air slams into cooler northern fronts. Supercell thunderstorms can spin up EF2+ tornadoes with very little lead time. On radar, rotation signatures inside storm cells give you a few critical minutes to reach shelter. Indianapolis averages several tornado warnings per year — know where your safe room or interior closet is before you need it.
Flooding & Flash Flood Risk
Flash flooding is Indianapolis's most persistent weather hazard. Slow-moving thunderstorms or tropical moisture can dump enough rain to overwhelm drainage systems within hours — especially in paved urban areas where water has nowhere to go. Check the radar to see where the heaviest rain is falling and which areas to avoid. The standing rule: turn around, don't drown. Never drive through flooded roads, even if they look shallow.
Ice Storm Risk
Ice storms are rare in Indianapolis but devastating when they hit. A quarter-inch of freezing rain coats everything — roads turn into skating rinks, power lines snap, trees come down. The radar shows whether you're getting rain, freezing rain, sleet, or snow — that distinction is critical. When Indianapolis gets an ice storm warning, stay off the roads and prepare for power outages that could last several days.
