2025 Sonsio IndyCar Grand Prix: Weather forecast for race at IMS road course

The Children's of Alabama Grand Prix is done, and the IndyCar paddock now looks over to racing on the IMS for the next few weeks. The Sonsio IndyCar Grand Prix will take place on May 10 after the weekend starts on May 9 as the 27-car grid readies up to take over the road course at the IMS.

IMS has been a staple on the racing calendar even before the championship was instituted. However, this week's race will focus on the road course that joined the fixture in 2014.

The 2.439-mile track will feature 14 turns, which Alex Palou dominated last year. The Spaniard would like to continue his winning streak at the track by completing a three-peat there.

The Chip Ganassi Racing driver has already won three of the four races held so far in the 2025 season and looks like he is in the best shape of his career. This makes him one of the favorites to take home the race victory, but he would have to face fierce competition from his rivals, as Team Penske has been particularly successful at the track.

This makes the upcoming weekend even exciting, so let's take a look at the session-wise weather forecast for the 2025 Sonsio IndyCar Grand Prix.
