Todays weather in Indianapolis - Sunday - 31 May 2026

Indianapolis is opening Saturday under a grey sky with temperatures sitting at 53 degrees and a light east wind at six miles per hour. No rain, no drama — just cool, overcast conditions that call for a light jacket or flannel if you're heading out early. Overnight stays right around that same 53-degree mark, so no surprises after dark.But here's the headline: Sunday delivers a near-30-degree turnaround. Mostly sunny skies and a high near 80 degrees make Sunday one of the best days of the year so far. Light east winds, three to seven miles per hour, and zero precipitation. Get outside.The week ahead looks like a gift for central Indiana. Monday brings partly sunny skies and a high near 78. Tuesday goes full sun, also near 78. Wednesday stays sunny at 79. Thursday pushes to 83 with unbroken sunshine. This is a sustained stretch of warm, dry weather — the kind Indianapolis doesn't always get this cleanly in late May and early June.The one flag worth noting: Friday's high reaches near 85, but a slight chance of showers and thunderstorms edges in Friday night. Saturday next week carries a 38 percent storm chance. Details will sharpen as the week progresses — treat it as a heads-up, not a plan-changer.Bottom line: layer up this morning, plan your Sunday outdoors, and make the most of a genuinely beautiful week ahead in Indianapolis.This episode includes AI-generated content.
