3/3/2014 3:00 PM 0.82 4.3 M 4.8 M An average of 2.5" of snow had fallen as of 7 am...with 4.3" when I got home from work late this afternoon. A number of cars were spinning out on I-270 and I-495 this morning, but overall, the commute to work took as long as it normally would, and roads were fine by 5 pm. The rain gage had 0.5" ice at the bottom, which likely explains the odd liquid equivalent from 4.3" of fluffy snow.
