Quick note about the most recent extended GEFS run initialized on the 29th — it completely lacks the Greenland High signal from more recent GEFS & EPS runs in mid January.

If this GH signal persists, it may indicate this extended GEFS run is a possible outlier for late Jan. pic.twitter.com/8Og3z9peyd
