Well after checking out the weather it seems like race day might be ok. There is a 40% chance of rain but in the afternoon/evening. (3 pm ) When looking at the Doppler radar there is a pretty big storm thats going to hit today in chicago but depending on its route (East / Northeast) will make the difference in tommorrow. I will look at the Doppler late tonight and it should be obvious if it will be ok to race atleast till Mid-afternoon.??? I guess it will be a last minute decision.
