As expected, showers and thunderstorms came through Mid-Ohio yesterday afternoon, and PWC had to cancel their GT practice and GTS Race 1. I think we'll see a similar situation today. The atmosphere over Ohio remains very moist, and there is an area of low pressure at the surface that is sitting over western Ohio, with a boundary extending east across northern Ohio.
There is some sunshine at the track this morning, which will help create some instability for showers and thunderstorms to tap into this afternoon. The most likely time for storms at the track will be between 2 and 6 pm, so I think the sessions that could be affected are IndyCar qualifying, Indy Lights Race 1, PWC GT Race 1, and Pro Mazda Race 2.
The low pressure area will be drifting east through the day, and should be over Pennsylvania tonight. However, there will still be an upper level disturbance that will be moving through on Sunday, which will keep a slight chance of showers and thunderstorms in the forecast. It looks like areas north of the track will have the better chances of rain on Sunday, but I can't rule out an isolated shower getting near the track in the afternoon. Most of Sunday will be dry with partly cloudy skies, so I'm not too concerned about rain affecting Sunday's races.
