Indianapolis, IN – A stretch of hot, clear weather will dominate Sunday across Indianapolis, offering one of the last full weekends of summer sun before storm chances move in early next week. Temperatures will climb to around 90°F with light south winds, making it ideal for outdoor plans across the metro.
According to the National Weather Service, showers and thunderstorms could develop after 2 p.m. Monday, especially in southern and western portions of Marion County. The risk will increase into Tuesday, when a 50 percent chance of storms could bring brief downpours, gusty winds, and lightning to the region. Residents planning commutes along I-465 or attending outdoor events should monitor conditions closely.
The dry, warm Sunday will be a prime opportunity for outdoor dining, back-to-school shopping, or attending community events before humidity and unsettled skies return. Those with Monday afternoon or Tuesday outdoor plans should prepare alternate arrangements in case of delays or cancellations.
While storms are not expected to be severe at this time, the unsettled pattern may linger through midweek, with additional chances for showers Wednesday and Thursday.
