The more poleward Aleutian ridge is the most important feature for our area in a Nina. That along with the stretched/southward displaced TPV idea the climate models have been hinting at would provide a mechanism for cold air delivery at times. During colder periods the thermal boundary could push over/just to the south of us. Models have also been hinting at possible HL blocking. Fwiw the advertised h5 look on the latest CFS runs look quite acceptable for Jan, and Feb too.
