4:25 p.m. wrap-up: All rain has moved out of the area and inaugural parade is proceeding under overcast skies and temperatures in the upper 40s.

Today’s noon swearing-in temperature of 48 degrees in Washington marked the 4th warmest January inaugural temperature on record. It was the warmest since George H. W. Bush’s inauguration in 1989 when the temperature was 51 degrees.  The other two January inaugurations warmer than today’s were Ronald Reagan’s first inauguration in 1981, when it was 55 degrees (the warmest on record), and Dwight Eisenhower’s first inauguration in 1953 when it was 49 degrees.

For the forecast for tonight and the rest of the weekend in Washington, see our PM Update, publishing at 4:30 p.m.

1:33 p.m. update: A small line of light showers is all that remains of the inauguration rain, and those are moving east out of the D.C. metro area. The rest of the afternoon will be mostly dry but chilly, with highs only expected to get to around 49 or 50 degrees. As of 1:30 p.m., the temperature was holding at 48 degrees downtown at The Washington Post headquarters.

12:02 p.m. update: Under overcast skies and a light breeze from the south (5 mph), the temperature in Washington is 48 degrees, making this the fourth-warmest inauguration on record. As President Trump took the podium, showers began to fell on the Mall. Spectators pulled out ponchos and umbrellas.

The rain is light, and it won’t last long, ending in the next 30 minutes.

11:42 a.m. update: Rain is on the doorstep. It will be light and short-lived, but people out on the Mall will get wet over the next hour or so. Showers should taper off around 1 p.m., after which the majority of the precipitation will be over.

11 a.m. update: Rain is approaching from the southwest and the temperature is up to 46 degrees at The Washington Post. It’s all but certain that showers will be moving through the Beltway as Donald Trump takes the oath and delivers his inaugural speech. They may begin as soon as 11:30 a.m.

Washingtonians woke up to showers, temperatures in the upper 30s and a lot of armed guards in the District. The security is going to stick around for the duration of the event, but the rain is taking a break before it returns to dampen official festivities.

Saturday events still look mostly rain-free, though it won’t be sunny, and patchy fog and mist is likely in the morning. Temperatures will be in the mid-50s. Overall, it will be the more pleasant day to be outside.

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 Secret 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.
