Brace for Thunderstorms Tonight, Then Blistering Heat Over 100° by Wednesday

As we go into Tuesday, July 22nd, the central region of Indiana is bracing itself for thunderstorms and record-breaking heat this week. Temperatures are forecast to climb beyond 90 degrees Fahrenheit, and heat indices are anticipated to be higher than 100 degrees. There is a possibility that isolated thunderstorms will occur across Indianapolis later today, mainly to the southwest of Interstate 74. This is the most immediate cause for worry. Even while strong storms are not anticipated, there is a possibility that scattered downpours could make the weather unsafe for activities that take place outside.

Temperatures are expected to continue to rise over the following few days, with highs reaching into the low 90s by Wednesday, as reported by the National Weather Service (NWS). As a consequence of this, the heat index, which is a measurement of how hot it feels outside, will go above the 100 degree Fahrenheit threshold beginning on Wednesday. Because to the intense temperatures, residents should make sure to drink enough of water and limit their time spent outside, particularly during the hottest portions of the day. This is especially important because heat-related illnesses could be severe.

On Thursday, the heat will continue, and there is a twenty percent chance that thunderstorms may form in the afternoon. On Friday, there will be a greater probability of thunderstorms returning, which will signal the beginning of an unsettling weekend. Conditions may shorten for a short period of time.

Residents of Indianapolis should be ready for a combination of sun, sporadic showers, and thunderstorms over the course of the next weekend. There is a sixty percent possibility of storms occurring on Saturday and Sunday, with maximum temperatures ranging from the middle of the eighties to the low nineties. Because it is quite possible that the extended heat wave will continue into the following week, it is essential to be well-prepared with fans, air conditioning, and a large amount of water.

  • Tuesday, July 22: Mostly sunny, high near 86°F. Low around 66°F. Winds light out of the east at 3-6 mph.
