Just want to use the eps as a quick example since it anchors the TPV over Siberia and blocks any true CPF and has a more toasty look up top:
Someone yesterday posted 2m temp anomaly maps like above to support their theory that the pattern going forward is crud. Again, I'm using the least favorable look EPS up top wrt those temp anomalies to show you we don't need a perfect setup or even near normal to get the surface near freezing. Even slightly AN 2m works during prime climo. It is below freezing at the surface same time on the means:
In any event, I would not be basing the pattern on 2m temps. Look at the lw pattern overall. And while the EPS isnt as stout as the GEFS (more reliable lately) and GEPS, it still has enough cold to the North via the Aleutian low and EPO nose. The key is getting the 250mb pac to retract which all signs say that will happen. The cold will rebuild thereafter.
