Indianapolis, Indiana – A sweltering holiday weekend is on tap for Indiana as highs surge into the 90s and heat indices approach 100°F from Thursday through Sunday, raising concerns for anyone spending time outdoors for Fourth of July festivities.
According to the National Weather Service in Indianapolis, lower humidity on Wednesday will give way to increasingly hot and muggy conditions starting Thursday, with high temperatures ranging from 89°F to 92°F through the weekend. Heat indices are forecast to climb into the 95–100°F range, especially Saturday and Sunday, posing health risks for vulnerable groups.
The hottest period will likely be during peak afternoon hours, with lows overnight only dipping into the low 70s. Cities including Bloomington, Muncie, and Terre Haute can expect oppressive humidity and heat-related impacts. Thunderstorms are also possible on Sunday, potentially disrupting travel and outdoor events.
Officials urge residents to stay hydrated, take frequent breaks in shaded or air-conditioned areas, and never leave children or pets inside vehicles. Those attending fireworks shows or community parades should plan ahead and check for emergency cooling centers if needed.
Heat advisories may be issued later this week as conditions intensify. Stay tuned to local alerts and limit outdoor activity during peak heat hours.
