BROOKLYN, MI – It could be a wet one this weekend at Michigan International Speedway, but sunny skies are projected for Sunday’s main event.

Friday and Saturday have a 50-percent chance of showers and thunderstorms, according to the National Weather Service.

Sunday’s chance of showers is expected to dissipate after 9 a.m. – well before the 2 p.m. green flag for the FireKeepers Casino 400.

A low-pressure system is expected to push into Michigan from northern Ohio, per the NWS. A high-pressure system should push into Michigan Sunday morning, causing clear skies and dry weather.

Models vary on timing, but the highest rainfall chances could occur late Friday into Friday night, with average rainfall of half an inch or more, an NWS Detroit update says.

Cars are scheduled to be on the track all day Friday and Saturday – including the Cup Series qualifying at 4:10 p.m. Friday, the ARCA Racing Series Zomongo 200 at 5:30 p.m. Friday and the Xfinity Series LTi Printing 200 at 1:30 p.m. Saturday.

Temperatures will peak in the high 70s throughout the weekend. At night, low temperatures are projected in the high 50s and low 60s.
