The day-10 temperature anomaly forecast at 10 MB reveals a stratospheric warming episode over northwestern North America. The warming causes an arctic air mass to develop over Northwest Russia in the 6-10-day period. On day-15, the stratospheric warming is widening and, frankly, looks scary as widespread arctic air is normally produced by this signature. However, for now, the “most likely” scenario is arctic air moves east across Eurasia and is shifting southeastward toward China much like the outbreak in December.
