As you can see the red region over north eastern Canada forces storms to not cut up into the lakes and mid section of the country. Instead they undercut the block and tend to form more towards the mid-Atlantic coast line. On the maps, starting late next week a few storms are starting to surface. The first possible one being late next week.
Although it is not showing this turning up coast yet, I would not be surprised if it did based on the progression of this pattern. In fact, there are a lot of similarities to the pattern we saw in winter of 2010 which if you remember was extremely active for the mid Atlantic in particular DC and Baltimore. Both the AO and NAO are going to crash, which creates the red blocking regions you saw on the first graphic letting cold stormy weather form. This pattern will start middle of next week and I can see it going into January. If we do not have snow on the ground for Christmas I would be very surprised. I will start to post on each individual storm threat as they materialize and I make a determination on what the chances are of them effecting our region. But in any regard after the rain we will see early next week things are really going to get fun if you like cold and snow. Here are temp departures from normal from the 17-22
