Well, both 2007 and 2008 had one....on the brighter side, maybe we can push it back since that type of gradient pattern may set up a bit later in the month, than those years.
It means a snowy month of December...targeted interior and high elevations of SNE first half, then north and northeast SNE second half.
January transitions to more huggers and cutters.
I am hopeful that it will be more gradient because I don't think the arctic will be awful...at least not until some point in January. Frankly, I am surprised that we are seeing much of any PNA at all in December, so certainly not shocked that the end is in sight.
