Good news is that environmental conditions will not be favorable for severe storms, but some of these showers could put down a good bit of rain in a short amount of time. I do not believe flooding will be an issue, but cloud-to-ground lightning could be. Remember the rule... "When thunder roars, go indoors!"
Winds will start off out of the west at 5-10 MPH, but will shift out of the southeast by the late morning hours. The afternoon high will be in the mid 70s, and the chance of rain at the track is at 40%. In case you would like to know what does a chance of rain actually means, then click here to read a post that Doug put up a few years back.
As always, radar is running on our site, and I'll have updates throughout the afternoon on Twitter at @RaceWx4you.
