Poor air quality slowly improving across central Indiana
INDIANAPOLIS, Indiana — Saturday, July 5, 2025, 7:00 a.m. EDT — After waking up to very unhealthy air quality in central Indiana, conditions are now beginning to gradually improve. Air quality alerts remain active through the morning hours, but sunrise is helping to disperse the trapped smoke from last night’s fireworks, as the temperature inversion—a layer of warmer air sitting above the surface—is beginning to break down.
Today: Mostly sunny, warm and slightly hazy
Early risers may notice patchy fog lingering near low-lying areas, but mostly sunny skies will dominate by mid-morning. There’s a slight chance of an isolated afternoon shower, but most areas will remain dry and warm. Expect high temperatures in the low 90s°F (around 32-34°C), paired with muggy conditions that make it feel even hotter.
Tonight: Clear and mild evening expected
The evening will remain mostly clear, providing a calm and warm night across Indianapolis and surrounding communities. Low temperatures will dip into the low to mid-70s°F (around 22-24°C), with light winds offering limited relief from the humid air.
Tomorrow: Increasing storm chances late in the day
On Sunday, a cold front approaches central Indiana, bringing with it a chance of scattered showers and thunderstorms, especially during the late afternoon and evening hours. Highs will again climb into the low 90s°F (32-34°C), maintaining the hot and sticky feel.
Looking ahead: Rain chances linger through next week
The 7-day forecast keeps rain chances on the table, with a frontal boundary lingering across the region. While rainfall totals are expected to remain low, the humidity will not let up. Dew points will hover in the uncomfortable to nearly miserable range, as daytime highs consistently reach the upper 80s°F (30-31°C), making for a sweaty and oppressive pattern through much of the upcoming week.
