Wonder when we get the shift if we can align to a miller B type of pattern temporarily
This is some very preliminary data, It has a lower sample size than I would like, and I’ll post a later graphic at some point, but this is the 15 day progression to a Miller B event.

This is great, looks like in the composite it's actually pretty warm more often than not leading into a Miller B about 7-10 days out, we get a -EPO to seed a trough in the Canadian Rockies with really cold Siberian/"truly" arctic air, it slides across the northern US about a day or so prior to a southern stream wave coming out of the southern rockies to overrun what cold air is left. I wonder what this looks like once you add in the events after 1978

Yeah, I would assume we see that strong -NAO signal go away. One thing I'm interested in doing is finding the Miller A/B cases w/ a +NAO, and +EPO, etc.
