On Friday at noon, President-elect Donald Trump will be sworn into office on the steps of the Capitol. Thousands of people will be in attendance to watch him take the oath, and it will probably be raining.
There’s still some uncertainty on the timing of the rain. Recent data suggests it will focus more on the morning than the afternoon. But one thing we’re fairly sure of is that showers will move through at some point Friday as crowds descend on Washington.
The temperature should peak between 48 and 50 degrees in the afternoon, so be prepared for chilly, damp weather in the 40s — dress in warm layers and stay dry with a poncho or rain jacket.
You can check the current temperature downtown using The Washington Post weather station.
The Secret Service is prohibiting umbrellas in the ticketed areas of the Mall, which affects a small fraction of the people who will be in attendance Friday.
In the nonticketed areas, small “tote” umbrellas will be allowed, according to the National Park Service, but not large umbrellas. This is a tighter regulation than was previously published in the ban list, which mentioned nothing about umbrellas.
If you’re going to take an umbrella, I suggest something small and cheap.
"Totes" style collapsible umbrellas will now be allowed on the parade route & the Mall on Fri, but no long, non-collapsible umbrellas

Friday weather timeline
6 a.m. — Only a slight chance of showers at this point. The temperature is only around 40 degrees.
9 a.m. — The temperature will be up to around 48 degrees and showers are likely.
12 p.m. — Low 40s and showers likely, though they may be starting to taper off at this point.
3 p.m. — Just a 30 percent chance of showers and temperatures will reach their high point for the day in the upper 40s.
6 p.m. — It starts to get a bit cooler. Light, isolated showers are possible but overall it looks like the rain will be over.
Saturday events still look dry, though it probably won’t be sunny. Clouds hang around but temperatures will be as much as 10 degrees warmer than Friday. Overall, it will be the more pleasant day to be outside.
Rain start and end time is still the uncertainty on Friday, but our confidence is very high that crowds will have to deal with showers at some point. Rain could begin as early as 7 a.m.and it looks more likely that the parade will be dry. Isolated, light showers are possible though the late afternoon. Perhaps the best news about this forecast is that we’re not expecting heavy rain — just a cool, damp day with showers on and off.
