From Nasa website:

Entry Flight Director Bryan Lunney and his team have given Discovery's seven astronauts a "go" for deorbit burn at 8:02 a.m. EDT to slow the shuttle on its descent to a 9:08 a.m. landing on runway 33 at Kennedy Space Center. The weather has improved and is both "go" observed and "go" forecast at landing time.

The landing will take the shuttle over Vancouver, northeast Washington, near Helena, Montana, over central Wyoming, across Kansas to northeast of Tulsa, Oklahoma, north of Little Rock, Arkansas, over Oxford, Mississippi, near Montgomery, Alabama, north of Albany, east of Valdosta and south of Columbus, Georgia, and, finally, over Florida east of Gainesville and west of Jacksonville.
