Will the elusive -NAO appear lol. Usually tougher to do with Nina, but it’s happened before. Nina is the talk that I hear as well. Hopefully a nice early start to winter.
Probably helped that the airmass was a bit warmer and held more moisture than typical arctic air masses. So you get that flow and block it, and much more moisture to squeeze out. It wouldn’t take much to get into the DGZ either in this airmass.
