I was wondering if the monsoon which hits Arizona/ New Mexico which normally begins in July is somehow early and shifted east. Then there is the big warm blob of water off the coast of California. I remember a winter when the Pacific cold fronts were coming to shore well north of normal. We had snow after snow where I live which is not normal. The fronts would then slide north and east dumping enormous loads of snow on Buffalo ( I know they get a lot but it was abnormal). This was in the late 70s. It was determined that 2 small Pacific ocean currents which normally move southward in winter, if I remember correctly, anyway they were not behaving as they should which was affecting the jet stream. This moved Pacific fronts northward causing wet cool fronts into near arctic fronts. Another thing this caused was less snow pack in the Rockies because everything moved east.
Sorry for being so wordy. I hope it makes some sense. I got interrupted 3 times before I finished.
