A long wave pattern consisting of a ridge over the Bering Sea and
West Coast of Alaska with a trough over NW Canada and Eastern
Alaska will persist through the week. A series of strong short
wave troughs will move through the ridge and into the West Coast
of Alaska every 2 days or so keeping the very stormy pattern
through the week. The West Coast and Western Interior and Arctic
can expect strong winds, heavy snow, possible blizzards and
the potential for some coastal flooding with each of these
storms. The Eastern Interior will remain cold through the week.
