The combination of La Niña and high Pacific North American (PNA) oscillation levels together with low NAO/AO values has made the western US unusually mild this winter. Even so, it's normal for the West Coast to be rather mild...they don't call Washington the "Evergreen State" for nothing...
Quoting: Anonymous Coward 1059768Great point about la nina however I've noted changes in the seasons for several years now. I am in California btw. Thanks for the reply- I'm in Colorado and so I can't speak so much for Cali's weather, although I've spent some time there. I've noticed over the last several years there has been more of a tendency than not to have high pressure over the western part of the country with an opposite pattern in the east and over Europe. A lot of it seems to relate to the AO (Arctic Oscillation) and the NAO (North Atlantic Oscillation). When those were highly positive, it was an almost opposite pattern here in 2006-07 than this past winter. That was also an El Niño winter.
