But it is not an outlier for Copenhagen and Helsinki, in fact the OP is
*warmer* than the ensembles for those two places at times in the forecast..
The ensemble mean has little change, and this tells me that there may be
considerable doubt how far west the *very cold* air gets but it is certainly
going to get cold with very cold air not far away to the east. Is this a
battleground scenario brewing again? Interesting.
