Dew points are currently running in the lower teens across much of the Washington DC Metropolitan Area. Roadway temperatures are well below freezing and the frozen ground underneath the pavement is not going to be very helpful when rain begins to fall across the Washington Area between 11pm and 1am.
The image below (courtesy Tropical Tidbits) shows the latest future-cast radar from the High-Resolution-Rapid-Refresh (HRRR) model. A warm front will slide through the area inducing a period of light freezing rain. For those of you with travel plans, it would be a good idea to stay off the roadways late this evening.
