On Thursday, a front will be pushing southward across Oklahoma and northern Texas. This will bring a good chance of showers and thunderstorms at the track as teams load in and start to practice. Storms will be possible at any time of the day, but it looks like the afternoon will have the best chances. Indications are that this front will push through on Thursday night, and high pressure will build in behind it. A northeasterly flow of dry air around the high should provide dry and mostly sunny conditions on Friday and Saturday, with comfortable temperatures and humidity levels both days.
