Inauguration Weather Forecast Update: Some Scattered Snow Showers Sunday

Temperatures have moderated significantly overnight, rising above freezing for the first time since Wednesday, when the high was 35°. Radar is showing light snow and mixed frozen precipitation over much of the Washington metro area, but surface reports indicate that little, if any, is reaching the ground.

The computer models have continued to disagree through this morning's runs, but the main storm development in the next couple of days is likely to be south and east of Washington. Some occasional light snow and/or sleet is still probable through Monday, with colder, but not extreme, temperatures returning by Inauguration Day.

Inauguration Day Outlook:
High 29-32
Low 20-22
Chance of precipitation: less than 20%
