Could we see snow in the next 6-10 days, I believe so, do not pay attention to individual runs of the operational models, they will have flaws in them run to run, but look at the ensembles and their means and they will show you the way.  I found this map on PSU EWALL website, the models are 12z runs of the EURO, GFS and CMC from left to right.  They pretty much agree on ridging in Alaska, our -EPO/+PNA feature, along with a ridge in northern Greenland and some ridging in northeastern Canada west of New Foundland.  Stay tuned, we could be tackling a major east coast snowstorm in this time frame.
