Dale Earnhardt Jr.'s sister, Kelly, needs that weekend rain to go away. 

On Saturday, NASCAR reporter Bob Pockrass tweeted, "Still persistent rain, easing but still too heavy to dry the track. Teams still have not started working on pre-race settings. It should be difficult to start on time tonight. It has to stop in the next three hours for the race to take place tonight."

In response, Earnhardt's sister said, "This rain is thwarting [Dale Jr.'s] plans to come to my 50th anniversary celebration tomorrow afternoon/evening, and I am not happy! Rain, rain, go away!"

Kelley and his younger brother, Dale, co-own JR Motorsports. They are two years apart in age.

Having said that, it appears that the Coke Zero Sugar 400 (and Kelley's birthday) will be a rainy one on Sunday.
