The 58th Presidential Inauguration will take place on Friday, Jan. 20, 2017 in Washington, D.C., in damp, overcast conditions.
Before this historic event, however, the traditional wreath-laying ceremony will occur at 3 p.m. EST on Thursday at Arlington National Cemetery to honor fallen soldiers.
By 4 p.m. the same day, the President-elect will be in attendance at a welcome celebration in front of the Lincoln Memorial.
On Thursday, partly cloudy and mild conditions are in store for these ceremonies. Winter coats and umbrellas will not be needed.

Inauguration Friday will begin with well above-average temperatures - the overnight low will not drop below 40.
"There could be a couple of dry hours to begin Friday before rain moves in for much of the day," said AccuWeather Meteorologist Kyle Brown.
By the time President Obama and President-elect Trump travel together down Pennsylvania Avenue on Friday morning, temperatures will be in the upper 40s with showers beginning to move into the Capital.
"This warm air will remain in place for Friday and Saturday, with afternoon high temperatures 10-15 degrees above normal," said Brown.
Despite an average high of 43, temperatures are expected to reach into the low 50s by early afternoon.
"Those in attendance Friday will be able to ditch the heavy winter coats, but rain jackets and umbrellas will be essential," said Brown.
While a wash-out is not expected, on-and-off rain showers will interfere with outdoor events throughout the day, including the oath of office and inaugural address. All are set to take place beginning at 11:30 a.m. at the West Front of the Capitol building and last through the early afternoon.
Similarly mild and wet weather is in store for the Inaugural parade on Friday afternoon. Waterproof shoes should be donned by any planning to attend, as streets, sidewalks and grassy areas will be wet.
Thereafter, all official inaugural events are scheduled to take place indoors.
However, a gathering predicted to be the largest in American history will take place in the nation's capital on Saturday.
The Women's March on Washington is set to begin with a peaceful rally at 10 a.m. on Saturday, Jan. 21 at the corner of Independence Avenue and Third Street.
"Dry air will move in later Friday night and will provide a dry day Saturday as high pressure builds in temporarily," said Brown.

While clouds are expected to stick around through much of Saturday, warm and dry weather will greet marchers.
"There could even be a peak of sunshine later in the day Saturday," said Brown.
Heavy weather-resistant clothing will be unnecessary for those in attendance, though waterproof walking shoes will be essential for those traversing the wet streets.
Those participating in one of over 600 "Sister Marches" across the country should be sure to check their local forecasts frequently and take precautions to dress appropriately.
