President-elect Donald Trump will take the oath of office from inside the Capitol Rotunda on Monday due to forecasts of intense cold weather, upending months of meticulous planning for a massive outdoor event with crowds sprawling down the National Mall.

Bitter cold – along with a chance of snow – is in the latest forecast for President-elect Donald J. Trump's Inauguration Day.

The coldest inauguration on record was President Ronald Reagan’s second swearing-in ceremony in January 1985, when the temperature was 7 degrees, followed by President Ulysses Grant’s ceremony in 1873 at 16 degrees and President John F. Kennedy’s ceremony in 1961 at 22 degrees.

The weather forecast in Washington, D.C., calls for a high of 24. That's much colder than the predicted high of 70 at Trump's Florida estate.

President-elect Donald Trump announced that he has ordered his inauguration ceremony to move inside the U.S. Capitol rotunda on Monday, Jan. 20, due to dangerously cold weather

The decision means the 250,000 people who had tickets to view the inauguration outside will no longer be able to do so - with a live viewing now taking place at the nearby Capital One Arena.

President-elect Trump's Monday inauguration ceremony is set to be colder than the norm. Why it matters: D.C. is preparing for 250,000 ticketed guests and thousands more at the National Mall for the outdoor ceremony — which has caused emergencies from extreme weather in its history.
