Snowfall totals have way over-achieved from Fredericksburg to southern Maryland:  The image above are reports from the public and trained spotters as of this morning (image courtesy NWS: http://www.weather.gov/lwx/pnsmap?type=snow)

Here is what may be on the ground before the change over to freezing rain (Image courtesy NWS/Washington):

Total storm accumulations of 10″ are not out of the realm of reality in areas that have already received 5 to 7″.

The models are clearly under-estimating how potent the cold air was out ahead of this storm system.  This worries me that our icing potential may be higher as a prolonged period of freezing rain could stack up to a quarter of an inch or more before the change-over to rain Tuesday morning.
