Given the near certainty of frequent cloud-to-ground lightning, I cannot imagine how this game can be played.
Other things being equal I'd go tonight but not if there's lightning. Re-scheduling should be relatively easy - I doubt they'd re-do it for tomorrow because of the concert but Monday would be a possibility since both the Nats and Braves have that date open (Braves start a series at Miami on Tuesday)...or possibly Sunday.
