Models in decent agreement through 60 hours. Long wave trough with
short wave extending from west from Fort Yukon. Short wave will
move to Arctic Coast by late tonight while long wave trough moves
westward. Upper level ridge will then build into the Southeastern
Interior starting Friday.
Upper level ridge that builds in to Southeastern Interior will
slowly retrograde back into Canada by late in the weekend.
Weak surface high pressure combined with strong low moving north
to near Kodiak Island by late Friday afternoon is causing a
relatively tight gradient across the West Coast of Alaska. This
has caused marine advisories to be issued for this area.
Chinook flow over the Alaska Range will cause gap flow winds in
the passes in the Alaska Range areas. This has pushed temperatures
up into the 30s in these areas today. Winds should weaken
beginning early Friday morning. Upper level flow becomes much more
southwesterly on Saturday. Some moisture will get caught up in the
southwesterly flow and spread from about Galena northeast to
Arctic Village by Saturday.
Brisk Wind Advisory for PKZ200-PKZ210-PKZ220.
