Stand-ins for Donald and Melania Trump practice Inauguration Day events

Less than a week before Inauguration Day, a smiling pair of stand-ins for the future president and first lady of the United States paraded around Washington D.C. to help organizers prepare for the big event.

Army SGM Gregory Lowery and SPC Sara Corry played the roles of Donald Trump and Melania Trump respectively, practicing the swearing in ceremony and even walking along the parade route.

It was sunny and brisk Sunday in the nation's capital when Lowery and Corry stood in for the future first couple, the actual Inauguration Day may have significantly less pleasant. Forecasters are currently predicting a high of 49 degrees Fahrenheit and rain on Friday, January 20 in Washington.

On that day, the president-elect and his wife are scheduled join President Barack Obama and first lady Michelle Obama at the White House in the morning for tea. The two couples will then travel to the U.S. Capitol, where Trump will be sworn into office by Supreme Court Justice John Roberts.

Mike Pence will be sworn in as vice president and then Trump will give his inaugural address.
