The warm front mentioned in the previous discussions will continue to be centered horizontally east-to-west over the Midwest. This is expected to set up a very strong temperature gradient over central Indiana, having a 20F degree difference in temperature in about 50 miles. Thankfully, Indianapolis Motor Speedway is expected to be on the warmer side of the warm front. During the day, the front is expected to push slowly southward and will bring a chance for isolated thunderstorms to central Indiana during the afternoon. A small shortwave trough in the upper atmosphere and winds from the south and southwest in the lower levels will help contribute to this chance. The Storm Prediction Center has Indianapolis under a Slight Risk (level 2 of 5) for severe storms, but this could change depending on the exact location of the warm front. So, be sure to stay weather aware if at the track, since these pop-up storms could be hit-or-miss. Expect winds from the south to southwest around 10-15 mph with gusts around 25 mph.
