It’s the end of an op run, but the 12z gfs shows the sort of evolution we want to see. Cutter brings down an arctic airmass behind it and an active pattern provides a series of strong short waves moving into that cold air. That cutter also acts as a 50/50 low to reinforce the cold. Then hopefully we get a nice snow event before our annual 70F Christmas Eve when the pac puke arrives with Santa.
