models in decent agreement through about 60 hours. Upper level low
somewhere near the Bering Strait will continue to drift westward
and weaken and then eventually dissipate by late Sat in the
central Bering Sea.
The NAM does keep an upper level low over the Arctic coast through
early Sat morning and that might not be too far out of line.
The upper level low near Dutch Harbor will continue to move
eastward to just south of Kodiak by early Saturday.
Numerous short wave troughs moving northward from Southeast Alaska
will continue to supply moisture to the eastern and central
interior through Sat. This will be the impetus for the showers.
Extensive fog on the Arctic coast will likely persist through Friday
morning given no dynamic change. The NAM has been consistently
suggesting brisk winds in zone 245 for the past week and nothing
has materialized...therefore no advisory has been issued for winds
in zone 245.
as forecasted...moisture has worked its way into the eastern
interior and the relative humidity values have definitely increased. This will
continue through at least Sat.
