I would give it a C+. Peak snowfall rates were only about .5-.6”/hr, and it underperformed with totals. Winter storm warning for 5-7” and ended up with 3.7”. HRRR and hires NAM didn’t do well at all. Honestly no models showed the proper distribution of snow.
For people near DC, I can see how this is a great event. It looked horrible for them 2 days ago then yesterday everything got better. Up here however, it looked the best 2 days ago (4-6”) and trended worse.
