Indianapolis started off sticky and warm on Saturday, June 13, with clear, muggy skies, temperatures in the low 60s, and dewpoints climbing as the humidity loads up the atmosphere. Sunshine and a south-southwest breeze will shove afternoon highs into the mid 80s, topping out at about 86°F. The real action waits until later tonight, when showers and thunderstorms are expected to roll in and pose the biggest threat to weekend plans. If you have outdoor events scheduled this evening, be ready to duck inside quickly once storms fire up.
Tonight Into Sunday Morning
Showers and storms are most likely between about 9 p.m. and midnight on Saturday, June 13, with some scattered leftovers lingering into Sunday morning (June 14). The National Weather Service puts the overnight chance of precipitation near 70 percent, with most spots picking up roughly a tenth to a quarter of an inch of rain. Forecasters caution that if the storms grow into a more organized line, damaging straight-line wind gusts would be the main concern for the Indianapolis area.
Sunday Outlook And Monday Cool Down
Sunday turns noticeably cooler, with highs near 76°F and scattered showers and thunderstorms possible through the morning and into early afternoon. West winds could gust up to about 22 mph later in the day. Drier air should work in Sunday night, clearing skies and setting up a more comfortable Monday with highs in the mid 70s. The overall unsettled pattern is expected to hang around into next week, with more chances for storms by midweek.
What To Do Tonight
If you are heading out on Saturday evening, build in a backup plan. Lightning and brief heavy downpours are the primary hazards, and any stronger cells could kick out damaging wind gusts. Give yourself extra time for late-night drives, tie down or bring in loose outdoor items, and keep a weather app or local radio station handy in case warnings are issued. This briefing is an update to our earlier weekend outlook; you can revisit the steamy setup we flagged earlier for more background on how this pattern has been unfolding.
