The 3am Monday upper air soundings from Nome, Kotzebue and Barrow all have new record high 500 mb heights for January for these locations. Translation: this is the strongest mid-winter high aloft of record over NW Alaska. Actually, its the strongest high aloft outside of summer over NW Alaska. Analysis from Environment Canada.
The record heights are:
Barrow: 568dm
Kotzebue: 579dm
Nome: 577dm
One of the impacts of this high clear skies over much of northern Alaska; there was a beautiful aurora here about 2am.
3pm AST Monday update: latest RAOBs have the following:
Barrow: 576dm
Kotzebue: 582dm
Nome: 580dm
Unbelievable.
