As we move into Tuesday, July 22nd, central Indiana is bracing for thunderstorms and extreme heat this week, with temperatures soaring above 90°F and heat indexes expected to exceed 100°. The most immediate concern is the potential for scattered thunderstorms across Indianapolis later today, primarily southwest of Interstate 74. Although severe storms are not expected, isolated downpours could make conditions hazardous for outdoor activities.
According to the National Weather Service, temperatures will continue to climb over the next few days, with highs reaching into the low 90s by Wednesday. As a result, the heat index — which measures how hot it feels outside — will surpass the 100°F mark starting Wednesday. These extreme conditions could lead to heat-related illnesses, so it’s vital for residents to stay hydrated and limit outdoor exposure, especially during the hottest parts of the day.
The heat will persist through Thursday, with a 20% chance of afternoon thunderstorms. While conditions may briefly cool, a higher chance of thunderstorms will return on Friday, marking the start of an unsettled weekend.
Looking ahead to the weekend, Indianapolis residents should prepare for a mix of sun, scattered showers, and thunderstorms. Saturday and Sunday will see a 60% chance of storms, with highs in the mid-80s to low 90s. The extended heat wave will likely extend into next week, so staying prepared with fans, air conditioning, and plenty of water is crucial.
