A causal reminder that, inland, we don't typically get big winds with SE flow. It generally stays elevated. That said, the NWS P&C for DC Tuesday evening has 30G45mph which is solid.
Snow maps are going to struggle on the boundary. Soundings and QPF are the way to go. I’m modestly happy with this run sitting on the western DC Beltway.
The column is holding on for dear life from 18 to 21z in the DC area. It eventually falls, but there’s almost 0.6” precip by 21z. Ratios would suck, but it would be a few inches of snow first in this scenario.
6" for December puts me only a few inches below normal on the year. As of December 10th I was still running last place over the past 10 years, but the three storms bumped me over 2016 and 2017.
