a train of yellows are lining up and making a beeline for dc.  i'm under a yellow right now and can confirm that visiblity is low, probably lowest so far.  measured close to 5" and that was about 15-20 minutes ago.

 

if we stay all snow, i see no reason we aren't at 15-20" by sunrise, and that might be conservative.  it's still in the low to mid 20s.  ratios still in our favor.

Here comes the heavy yellows for us western folks that were in the advisory earlier. Its going to get amazing in about 30 minutes.

 

10:00 Update

Moderate snow

20 Degrees

6.4 total accum.

2.5 in last 3 hours

 

Feels so refreshing outside. Much better rates over the past 3 hours. Time for a nap. I want to get up in time to watch the Deform band destruction.
