Dangerously cold temperatures are expected on Inauguration Day, sending millions of spectators to find other ways to watch the historic swearing in.

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.
