Current radar does look impressive but two things are going to happen as it progresses eastward:

1) It has to cross the mountains, this process will tear up a lot of the precip

2) The system will get sheared a little bit by the s/ws to the north running ahead of this system increasing the confluent flow they will run into.  

No more diamond snow :(

Our snowflake will travel through a much deeper layer of supercooled water droplets.  This will allow the snowflakes to become "sticky" and when they pass through that area on the sounding that is isothermal (roughly around 900mb) they will stick together and produce some nice snowflakes that will seem gigantic compared to the recent ones we have seen.  

Now there will be some instability hanging around in the lower levels coinciding with the greater forcing, but it is to be determined how this will impact the forecast.  I would not be surprised to see a nice band develop, but I am going to play the odds here and go with a solid 0.5-1" for the area.  The lack of forcing extending into the snow growth zone and ratios coming down I don't see anything more than an inch here unless we get some banding.  Check back later for nowcast!
