Northern Alaska forecast discussion
National Weather Service Fairbanks Alaska
458 am akst Sat Dec 15 2018
a relatively quiet weather pattern will continue today for most
of northern Alaska. The main weather related issue is the
continued northerly winds through the Bering Strait.
Aloft, at 500 mb, a 496 dam low centered south of Wainwright will
move to near Point Lay by this evening where it will persist into
Sunday before starting to move off to the north on Monday. A 500
dam low will develop over the Yukon Delta tonight. This low will
move to near Bethel by Sunday evening before starting to move to
the north reaching Galena by Monday afternoon and Point Lay
Tuesday afternoon. Southerly flow aloft will set up Sunday over
the eastern half of the forecast area and will persist through
Central and eastern interior: snowfall is expected today along a
front that will travel from southeast to northwest across the area
today before dissipating this evening. The front is currently
stalled just to the east of fairbanks; however it is expected to
begin moving again later this morning. Up to one inch of snow
accumulation is expected for most locations along the front;
however, areas just east of Fairbanks, where the front is stalled,
could see up to two inches of snow. Clearing skies are expected
behind the front which will allow temperatures to fall back into
into the -10 to -20 range by tonight for most valley locations.
Southerly gap winds are expected today in Alaska Range passes with
gusts up to 40 mph. The gusty winds are expected to die down by
this evening. We will get a little bit more cloud cover for Sunday
and Sunday night which should result in a weak warming trend in
temperatures. A northward moving front will bring snowfall Sunday
night into Monday, mainly to areas to the west of Fairbanks. This
system looks to bring 1 to 3 inches of snowfall to areas west of
North Slope and Brooks range: no big issues expected this weekend.
Some light snow is currently being observed along the coast from
utqiagvik west. Light snow will continue in this area today before
tapering off this evening. Much of the area east of Barrow has
clear skies this morning. This has allowed temperatures to drop
into the -20 to -30 range at most locations. We do expect more
cloud cover to move into the area late tonight which will cause
some warming. A northward moving front will bring snowfall to
areas west of the Dalton Highway Monday night into Tuesday.
West Coast and western interior: northerly winds of 20 to 30 mph
will continue today from the Bering Strait south to St. Lawrence
Island. The winds in this area are actually lower than what was
being observed yesterday during at this time. Snow showers that
will cause significantly reduced visibility at times are expected
today for the Bering Strait coast, St. Lawrence Island and Little
Diomede. These showers will generally be of short duration.
Northerly winds will increase through the Bering Strait south to
St. Lawrence Island late Sunday into early Monday with gusts up to
40 mph possible. Elsewhere, relatively quiet weather is expected
today with some flurries and fog close to the coast. A front will
bring snowfall to the western interior Sunday night into Monday
with 1 to 3 inches of snowfall expected.
Coastal hazard potential days 3 and 4...none.
