models roughly similar through 60 hours. Current low with upper
level vertically stacked low on the chukotsk peninsula will absorb
energy from a low near Kamchatka peninsula and deepen rapidly.
This will extend to an upper low at about 80n 140w this evening.
The surface low will move to near the chukotsk peninsula as at a
depth of 971 mb by Sun afternoon. The warm front portion will move
to about the Seward Peninsula at the same time.
A deep upper level trough will develop over the West Coast by Monday
while a decent upper level ridge develops over the eastern 2
thirds of the state Monday as well.
As the surface low rapidly develops in the Bering Sea...strong
southerly winds will develop ahead of the low and this could
create high surf conditions along the portions of the West Coast
and Norton Sound.
Heavier snow will spread over the West Coast Sun night and Monday.
Although temperatures will be warm enough initially to prevent a
majority of the snow from blowing...after the cold front passage
on Monday wrap around snow will likely create many areas of blowing
snow in the Bering Strait and the coastal areas.
Winds along the eastern Brooks range will likely increase Sun
night and may cause local blizzard conditions through passes.
Coastal hazard potential days 3 and 4...none
