Air quality improves in central Indiana after a smoky start
INDIANAPOLIS — This Saturday, July 5, central Indiana woke up to very unhealthy air quality, primarily due to trapped smoke from July 4th fireworks. A temperature inversion — a warm air layer aloft — combined with light surface winds helped keep smoke close to the ground overnight. However, with sunrise now behind us, this inversion is breaking down, and air quality conditions are steadily improving across the region.
Today: A hot, mostly dry Saturday for Indiana
Expect mostly sunny skies across Indianapolis and surrounding areas, though some patchy fog may linger briefly this morning. There’s a very slim chance of a stray afternoon shower, but most areas will stay dry. Highs will climb into the low 90s°F (32–34°C), with sticky humidity making it feel even hotter.
Tonight: Clear skies and warm overnight
Skies remain mostly clear overnight, with low temperatures settling into the low to mid-70s°F (22–24°C). Humidity levels remain elevated, keeping the air muggy through the early morning.
Sunday: Storm chances return late in the day
A cold front will begin approaching central Indiana by late Sunday, increasing the risk for scattered showers and thunderstorms late in the afternoon and evening. Most of the day will stay dry, with daytime highs once again in the low 90s°F (32–34°C). Heat and high dew points will contribute to uncomfortable outdoor conditions.
Looking ahead: Rain chances linger, heat holds
The 7-day forecast features multiple small chances for rainfall as a frontal boundary hangs nearby. Expect highs in the upper 80s°F (30–31°C) much of the week, with dew points remaining oppressive, making conditions feel miserable at times, especially during peak afternoon hours.
