Indiana’s spring warmth is building fast this afternoon, with bright skies and dry pavement giving way to a sharp swing in conditions by Sunday evening. Temperatures climb into the upper 70s today, and the air feels mild, almost early summer-like. That warmth intensifies into Sunday, but changes arrive quickly after 2 p.m. as scattered storms begin to develop.
According to the National Weather Service in Indianapolis, highs reach near 82°F Sunday before isolated thunderstorms form between 2 p.m. and 5 p.m. Winds shift southwest at 8 to 16 mph, with gusts near 20 mph. Rain chances remain near 20%, but brief downpours could reduce visibility along I-65 and I-70 during peak travel hours.
Conditions turn more unsettled Sunday night. Showers increase, with a 40% chance of rain and gusts reaching 23 mph. Wet pavement and reduced visibility could slow travel into early Monday. Plan extra time if driving late Sunday.
By Monday morning, a noticeable cooldown takes hold. Highs struggle to reach 52°F, with lingering isolated showers early. North winds increase, making it feel brisk compared to the weekend warmth. By Monday night into Tuesday morning, temperatures drop to near 35°F. That raises a risk of patchy frost and even brief slick spots on bridges if moisture lingers.
Skies recover by Tuesday afternoon with sunshine returning and highs near 57°F. Still, the temperature swing may stress early spring plants and impact morning commuters.
Looking ahead, a gradual warm-up resumes midweek with highs nearing 60°F and beyond. More updates are expected as temperatures fluctuate. Traveling Sunday or early Monday? Watch for sudden changes and share what you’re seeing on the roads.
