Inauguration Weather Forecast Update: Numb or Number?

Following on the heels of a very light dusting of snow around dawn this morning (all 3 major airports reported a trace), northwesterly winds gusting as high as 38 mph are bringing an Arctic chill to the Nation's Capital area. Temperatures which have remained in the 20s all day are expected to drop to the mid teens tonight.

Below-average temperatures will persist through the weekend and into Inauguration Week, but the coldest readings are likely Friday into early Saturday, with a high in the low 20s and a low Friday night in the upper single digits.

The outlook for Inauguration Day is for somewhat less numbing conditions, but with a high near or a little above freezing, spectators will definitely feel a chill:

High: 31-36°
Low: 18-23°
Chance of precipitation: 20%

Other forecasts:
National Weather Service
Partly sunny, with a high near 34.
