A closed low will retrograde westward over southern Alaska to reach the Bering Sea Thursday/Friday where it will further diminish next weekend. There is lingering potential for western and southwestern Alaska snow Thursday into Friday. Underneath, deepened north Pacific storms will track near the Aleutians Friday-Saturday and again Sunday-Monday. Otherwise, expect a relatively benign threat pattern for Alaska with nondiscript flow settling over the rest of the state. The WPC Alaskan medium range product suite was mainly derived from a composite blend of reasonably compatable/clustered GFS/ECMWF and GEFS/ECMWF ensemble means days 4-6 Thursday-Saturday. Leaned heavily on ensembles days 7/8 next Sunday/Monday amid growing forecast spread to best maintain WPC forecast continuity. Schichtel
