Regarding February, I noticed something on the Euro weeklies. If you go to the link below, which is Arctic 2M temps, and progress through the weeks, keep an eye on the sw coast of Canada. As you get to week 2, you can see warm temps being replaced with average and BN temps, then that colder area expands and slides SE into the Plains. some BN and normal come week 3. Week 4, the normal temps weaken to a little warmer than normal, followed by week 5 and it is AN. But then at week 6, and here's my point, the AN temps are replaced with normal temps and the whole process from earlier in the run "appears thru these weenie eyes," to be getting ready to repeat.
One difference I see is that instead of large areas of both BN and AN temps on the other side of the Pole at week 1, there's mainly normal temps. Effects if I'm "somehow " correct with the repeat pattern idea, I don't know. But my weenie brain says normal temps across the Poles come the end of January are cold vs recent years, and that would maintain seasonal, if not BN, cold.
This could all change with today's or future runs as there's plenty of time for that, but that area in sw Canada grabbed my attention. Of course, if the cooling is simply from the ridge decaying, that would likely negate my thoughts.
