Sensible decision to move the festivities indoors rather than on the National Mall, which would be covered in 3-4” of freshly fallen snowfall.
On the other hand, the Philadelphia NFL playoff game vs. the Los Angeles Rams will be played outdoors in snowy and cold conditions on Sunday afternoon. Temperatures in the 20s with 3-5” of snowfall.
