Northern Alaska Forecast Discussion
National Weather Service Fairbanks AK
325 AM AKDT Tue Apr 4 2017

.DISCUSSION...

Models...Big picture agreement remains good through around day 4
before diverging. 04/00Z runs initialized well at 04/06Z against
the surface analysis. Model output temperatures continue to be all
over and generally way too cold so will maintain continuity in
temperatures by using previous day and current forecast database
as a starting point, then make only minor adjustments. No
expecting much precipitation with the system moving north into the
state today, so will lean toward the SREF solution for
precipitation the first 48 hours.

Aloft...At 500 hpa...Pattern aloft has settled down a bit with
ridging extending west across the interior, A 531 dam high 200 nm
northeast of Point Barrow, a dissipating 519 dam low over St
Lawrence Island, and a 506 dam low 250 nm south of Kodiak City
this morning. Everything remains fairly stagnant today with the
high over the arctic building to 535 dam, the ridging over
interior Alaska rotates to the northeast and weakens, the low near
Kodiak Island weakens to 510 dam, a 517 dam low develops in the
northeast Pacific and moves to 300 nm west of the Queen Charlotte
Islands, and the low in the Bering Strait dissipates. By Wednesday
afternoon the high over the arctic remains 200 nm northeast of
Barrow at 536 dam, the ridging over interior Alaska hangs up over
the northeast corner of the state, and the lows near the Gulf of
Alaska merge with a 511 dam center 200 nm southeast of Kodiak
Island. A fairly strong shortwave will move over the southeast
panhandle Tuesday night and lie from Yakutat east, moving to lie
from Seward to Fairbanks Wednesday evening as it rotates around
the low, and over the west coast by Thursday morning. At 850
hpa...Temperatures warming a bit the next 24 hours, then cooling
Wednesday night a few degrees, then remain relatively flat
through the remainder of the week.

Surface...Weak troughing over the state with main axis southwest
to northeast across the state and a secondary trough over the west
coast. High pressure with ridging extending west remains over the
eastern arctic with a 1026 mb center 400 nm north of Kaktovik.
The high will drift east into Canadian waters through Tuesday then
stall 300 nm north of Banks Island Thursday, then drift south to
Banks Island Saturday morning. A 975 mb low 200 nm south of Kodiak
City will weaken as a 969 mb low moves from the northeast Pacific
to 300 nm west of Prince of Wales Island late this evening and
absorbs the low near Kodiak. The low then move northwest into the
southern Gulf of Alaska by Wednesday morning, and to 200 nm
southeast of Kodiak City late Wednesday at 970 mb. A weather
front will move over the southeast panhandle Wednesday and push
over the southeast interior Wednesday evening, then stalls as
it moves over the Alaska range.

Arctic Coast and Brooks Range...Patchy stratus continues to be a
bother, especially with the Aviation forecasts. NPP-VIIRS 24 hour
Microphysics RGB imagery from 03/2222Z indicates there is more
making its way around the base of the ridge that will impact he
area today and tonight. Not expecting any significant snow with
the stratus, but a few flurries may fall. The ridge continues to
build and leeside troughing is developing over the arctic plain so
the gradient over the eastern arctic coast is starting to tighten
up a bit. Winds already east around 20 mph gusting to 30 mph will
increase to 30 mph gusting to 45 mph and blowing snow and fog
will reduce visibility to around 1/4 mile so will issue winter
weather advisory for zone 204. Zone 203 will also be getting
stronger winds, but expect visibility will generally be above 1/2
mile in blowing snow so will hold off on any advisory for now.
Temperatures steady or slowly warming through the week.

West Coast and Western Interior...Cloudy for most areas today, but
generally dry. With the weak trough over the area there may be a
few showers over the lower Yukon Delta, and in the Bering Strait.
Winds generally north to northeast with the strongest winds on the
outer Capes and St Lawrence Island at 15 to 25 mph. Winds 10 to
20 mph for the remainder of the coastal areas, and 5 to 15 mph for
the inland areas. Temperatures a bit warmer today, then slightly
cooler the remainder of the week.

Central and Eastern Interior...Cloudy across the area today, but
not expecting any precipitation as the front moves over the state.
Temperatures slightly warmer today in spite of the clouds as
some warm air works north into the interior, then a couple
degrees cooler through Friday. Winds generally east and picking up
a bit across the interior to 10 to 25 mph for most areas. There is
a slight chance of snow in the eastern Alaska range and Eastern
Interior Wednesday night as the decaying front moves to lie from
Talkeetna to Eagle before breaking up. A gap flow wind event in
the eastern Alaska Range is setting up for Thursday morning with
south winds gusting around 45 mph.
