Original post:
The 3.7" of new snowfall as of midnight brings the official Washington, DC seasonal total to 48.8", moving this season ahead of 1995-96 into second place. This winter is now less than 6" away from the all-time Washington seasonal snowfall record set in 1898-99.

The February total of 24.8" still remains in 4th place, however, behind 2003.

With the snow having changed to freezing rain for the last couple of hours, accumulations overnight will likely be reduced from earlier expectations.
