Inauguration weather update: Chilly but big cold waits until night; late day snow showers?


Forecast inauguration temperatures and wind chills 4 a.m. to midnight in Washington, D.C. (National Weather Service)

Inauguration Day is closing in and the weather?... well, it doesn’t look all that bad, at least for the morning through mid-afternoon. But it turns very cold and wintry at night.

While it won’t be unseasonably cold early on, it will be plenty cold enough for those spending most of the day outside, mainly under partly to mostly sunny skies. Early-to-mid morning temperatures rise from around freezing into the mid-30s, but could be in the upper 30s to near 40 by the 11:30 a.m. swearing-in ceremony, and likely into the low to even mid-40s during the afternoon Inaugural Parade scheduled to start at 2:35 p.m.

Winds will generally be from the south around 10 mph through mid-afternoon, but will increase to 10 to 20 mph ahead of a second surge of cold air and disturbance swinging by to the north.


Simulated temperatures at 10 p.m. from the NAM model show temps right around 30.
It becomes decidely more wintry in the late afternoon and especially into the evening. As the winds pick up out of the northwest (gusts to 20-30 mph), cloud cover increases with even a few flurries and snow showers. Although there’s just a 30 percent chance you’ll see snow, Inaugural ball-goers should beware - if any heavier snow showers develop, an evening dusting could materialize. Temperatures fall back through the 30s into the upper 20s before midnight. Evening wind chills dip into the 20s and even the high teens late.

Stay tuned for updates tomorrow for the latest on any snow showers blowing into the region.
