Indianapolis, Ind. – Central Indiana will ease into a quiet but changing weather pattern over the next several days, with patchy fog Friday morning followed by a mild weekend and a noticeable cool-down early next week.
Fog Concerns for Early Commuters
The National Weather Service in Indianapolis warns that patchy fog could slow morning commuters on Friday, especially in low-lying and rural areas. Drivers traveling along interstates and highways leading into Indianapolis, Bloomington, and Lafayette should be prepared for reduced visibility near daybreak. While the fog should lift by mid-morning, caution is urged during the early hours.
Weekend Weather Outlook
Friday will bring partly cloudy skies and mild conditions, with highs ranging from 77 to 84 degrees. Overnight lows will settle in the low to mid-60s, maintaining a late-summer feel.
By Saturday, temperatures will climb slightly into the 82–86 degree range, though isolated showers may develop across portions of the state. While rain chances remain scattered and brief, outdoor activities could face minor interruptions.
Sunday marks the beginning of a notable temperature shift, with highs cooling into the mid-70s under mostly sunny skies. Lows will dip near 55 degrees, ushering in a fall-like feel unusual for late August.
Fall-Like Stretch Next Week
A stronger push of cooler air will dominate next week, bringing below-normal temperatures across central Indiana. By Monday morning, lows will fall near 50 degrees, with daytime highs struggling to reach the lower 70s. This pattern may persist through much of the week, keeping conditions crisp and comfortable.
Residents should plan ahead by keeping jackets and light layers handy, especially for mornings and evenings. The cool spell offers an early taste of fall, with little chance of extreme heat returning soon.
