Anchorage and much of Southcentral’s bout of repeated heavy snows has ended as the weather pattern has shifted to a colder drier northerly winds aloft.
A bit more detail from when I had my first official lead forecaster job in ANC (1977) ... the 'classic' setup for prolonged (12-24 hrs+) snow events in ANC generally required the GOM storm to occlude out near Middleton Island with the decaying center then drifting towards & then into Prince William Sound where i would spin itself out. ANC surface winds were almost always northwesterly.
Indeed, that is a classic pattern. In this case the flow aloft was flat enough even with the low near Kodiak that the winds aloft never backed around to SE.
