Aloft...currently a 523 dam low center in the central Bering
will drift to the south Thursday morning and merge with low
pressure in the Gulf of Alaska Thursday afternoon.
High pressure aloft will remain over the Beaufort and chukchi
seas through the remainder of the week and bring several bursts of
cooler air from the Arctic to the northern coast of Alaska.
Weak ridging aloft over the eastern interior on Thursday then
will deamplify on Friday and rebuild over the Brooks range over
Surface...a ridge of high pressure extends across the North Slope
and low pressure in the southern Bering and Gulf of Alaska for
Thursday. A fairly strong pressure gradient over most of the
Arctic coast will persist into the weekend. A 970 mb low is in
the Gulf with associated warm front moving north.
North Slope...northeast to east flow will continue through
Saturday for the North Slope. Areas of stratus and fog will likely
linger into the weekend. Highs in the middle to upper 20s are
expected through Sunday.
West Coast...strong winds near the Bering Strait and near
Point Hope this afternoon into Friday due to a strong pressure
gradient. Scattered rain showers for the Yukon Delta with
approaching frontal boundary.
Interior...a wave of energy will move up from the south tonight
into Friday. A chance of rain and snow showers for parts of
the interior expected. Light amounts of precipitation expected. Another
chance of precipitation on Saturday but mainly for the eastern interior
and eastern Alaska Range. Gusty winds over higher terrain due to
pressure gradient between high pressure over the Arctic and lower
pressure in the Gulf of Alaska.
