The system develops as a Low passing between two anticyclones. So I suppose it doesn’t explain the occurrence of Blocking Highs since they are already there. But looking at the chart for the 1July at 18:00 the cyclone in the middle of the north Pacific breaks in between the already split anticyclone off the Gulf.
Then the tell tale jellyfish shaped frontal system develops. The analogy of the term Jellyfish-like fronts is appropriate I imagine as the jellyfish we get in Britain in the warm summers come in the same direction. I suppose the same is true with marine life in the Pacific.
Whatever the case, by noon on the 3rd the system has that look. It breaks up a day later so something interesting got in the way on the 4th. On the 5th it has made it to British Columbia and a small anticyclone builds in the Gulf of Alaska.
Another one builds on the midnight of the 6th at 40 N. 170 E. that has a little more success.
This one is a little more determined and holds its form a lot better getting to the Gulf at Midnight on the 11th. It was linking up to another one back at base camp but something happened midnight on the 12 to upset things.
By noon on the 14th we are back with the flaccid North Pacific oscillation anomaly. However, there appears to be another one in the loop. Check out > Pacific Products > North Pacific Surface Analysis at:

Check the “Select Size” tab for 3, 7 or 28 days (they only go back a month so grab them while you can.) If you are using Linux check the Javascript loop.
Here are the charts for the NWS storm reports:
These go back to 2009 more or less. Analysis methods and presentation has changed slightly since 2009, but they are worth collecting -if you can find something to compare them with. Even the Meteorological and Climategate Office supply data going back that far*, I am sure you will find it worth it.
