North Pacific Temperature Update

I added a new post on the Alaska "Blob Tracker" blog this morning:

The contrast between a strongly positive PDO phase and now strongly negative NPM phase is quite remarkable.  Looking at past years in which this combination was observed during winter, it is typical to see a stronger than usual Aleutian Low and a strong ridge over the western half of Canada.

Unfortunately for snow-lovers, this pattern is a distinctly dry one for interior Alaska and a distinctly warm one for southern and southeastern Alaska.  Of course, there's no guarantee that the North Pacific temperatures will remain in this pattern for the next 3 months, but I wouldn't want to bet against it.
