As I'm sure everyone has noticed, it has been downright frigid this week, and it will stay that way for tomorrow's little event, meaning that any precipitation will fall as snow. While the wet snow that we're accustomed to in DC has 10:1 snow:liquid ratios, tomorrow's powdery dendrite flakes will lead to ratios somewhere around the 15:1 range, amplifying our snowfall total.
However, there really isn't much precipitation to help us out, as the NAM forecasting model (the most generous in terms of snow), only gives us .09 inches of precipitation, which would lead to a measly 1-1.5 inches of snow. While I think a decent coating is likely, this storm could fizzle out into flurries. On the other hand, there is little possibility for this weak system to pick up steam, and anything more than 2-3 inches isn't happening.
Our recent storms have mildly overperformed their quite modest predictions, so I think about an inch of powdery snow is what we'll end up with Saturday morning. While aesthetically pleasing, it will be the 730th day without two or more inches of snow, a drought that has been active since the storm on January 26, 2011.
