Indiana – Thick clouds and warm, humid air are building over Indianapolis right now, and the atmosphere is primed for storms to intensify quickly by late evening. Roads are already damp in spots, and conditions could deteriorate fast after sunset.
According to the National Weather Service in Indianapolis, scattered thunderstorms develop through the day before a stronger line of storms arrives late evening into early Friday. Storm coverage increases to near 100%, with rainfall totals between 1 and 2 inches possible. Lightning, heavy rain, and localized flooding will pose the biggest threats.
Indianapolis, Carmel, and Greenwood could see the heaviest rain and strongest storms late tonight into early Friday morning. Expect ponding on I-65, I-70, and I-465, especially in low-lying areas. Visibility may drop quickly during downpours. Plan extra time if traveling and avoid water-covered roads.
Storms may also produce gusty winds and small hail, particularly with stronger cells. While widespread severe weather is not guaranteed, a few storms could intensify quickly. Keep phones charged and enable weather alerts through the evening hours.
By Friday, showers taper off through the morning, with cooler air settling in and highs near 50°F. Skies begin to clear later in the day, but temperatures drop sharply into the upper 20s by late night.
That sharp cooldown raises concern for refreezing on wet surfaces. Bridges and overpasses may turn slick early Saturday. The weekend turns calmer, with sunshine and highs in the low 50s Saturday and low 60s Sunday.
Looking ahead, early next week brings a return to milder air and additional storm chances. Stay alert as conditions evolve quickly. Are you seeing lightning or heavy rain in your area yet?
