642 AM AKST Mon Jan 20 2025
.SYNOPSIS...A series of storms will continue to impact the West
Coast, with the next storm arriving late tonight bringing heavy
snow and blowing snow. Winter Storm Watches and Warnings are in
effect. The Interior will be mostly dry with well above normal
temperatures through the rest of the week, along with periods of
strong south winds through Alaska Range passes and east winds at
Delta Junction. The North Slope will also have temperatures well
above normal through Tuesday, with cold air slowly filtering back
in from the west. A significant pattern shift will take place late
this week, likely bringing a number of strong storms to the West
Coast and precipitation into the Interior.

.DISCUSSION...
Key Weather Messages:
Central and Eastern Interior...
- Fairbanks picked up 1-2" of snow overnight. Snowfall will
tapering off this morning.
- Heavy snow fell along the Richardson Highway in the eastern
Alaska Range overnight. Snow is tapering off this morning. The
Winter Weather Advisory has been cancelled.
- Mostly dry conditions expected until the end of the week with
high temperatures well above normal, mainly in the 20s above
zero.
- South winds gusting to around 50 mph through Alaska Range passes
and east winds gusting to around 40 mph at Delta Junction are
expected at times Tuesday and Wednesday.
West Coast and Western Interior...
- Monday there will be some brief calm conditions as another low
paired with a strong arctic front moves into the Bering by
Monday evening. This arctic front will potentially bring a
narrow band of long duration heavy snowfall from the Y-K Delta
to the Kobuk Valley. The exact location of the band is still
uncertain, however currently we are looking at it to be from
Hooper Bay to Unalakleet then to Ambler with it's western edge
of the band being somewhere in between Elim and Nome. Snow
totals could be up to a foot in some spots depending on snow
ratios. Winter Storm Watches have been upgraded to Warnings for
most of the area, except for along where we expect the western
edge of the snow band to be. These have been left as Watches as
a lot of uncertainty still remains.
- Another low pressure system moving into Bristol Bay on Tuesday
morning looks to bring northeasterly wind gusts up to 35 mph
from the Seward Peninsula to the Y-K Delta. We could see
significant visibility restrictions in areas that are receiving
the heaviest snow as well as gusty winds.
- After this next system moves out of the area Wednesday morning,
there will be another system Thursday and Friday. This system
looks to be bring heavy snow initially, then mixed precipitation
as it moves northeast through Saturday. Expect this to be an
impactful system.
North Slope and Brooks Range...
- Well above normal temperatures continue today from the Brooks
Range to the Arctic Coast. Expect temperatures mainly in the
20s, with colder air filtering back in from west to east through
Wednesday.
- Falling snow along with southerly gap winds through the Brooks
Range passes up to 40 mph will cause blowing snow and low
visibility through Tuesday. A Winter Weather Advisory is in
effect.
Forecast Analysis and Confidence...Weak high pressure exists over
Interior Alaska with weak low pressure in the arctic and in the
Aleutians. Weak southwest flow persists aloft as a deep and cold
upper level low lies over Eastern Siberia. Ridging aloft will
build over the Interior today as a warm front spreads north along
the West Coast, bringing snow before halting from Savoonga to
Nome to Anaktuvuk Pass. Depending on where exactly this system
stops, areas beneath it will likely receive heavy snow of up to or
even slightly more than a foot through Wednesday afternoon. A
weaker low pressure system moves to the Western Bering Sea on
Wednesday night, bringing another round of light snow through
Thursday before a much stronger storm takes aim at the region on
Friday.
Models are not in good agreement on the placement of precipitation
with the first system. The ECMWF has been the most consistent, and
the forecast reflects that solution with a more SW/NE oriented
snow band. The NAM and GFS bring the precipitation further west
and orient the band more N/S. Opted to keep the western areas as
Winter Storm Watches in case daytime models runs begin to show
more precipitation than the ECMWF is showing there. Otherwise, we
used a general blend of models for the forecast overnight. We
blended the NAM and NAMNEST for winds and made some hand edits to
increase gap winds through Alaska Range passes and at Delta
Junction beginning Tuesday afternoon.
Extended Forecast Days 4-7...A major pattern shift is likely by
the end of the week as flow turns more southwesterly and a number
of strong low pressure systems enter the Bering Sea. While the
exact tracks of these lows are still uncertain, the overall
pattern is favorable to bring an abundance of warm air and
precipitation northward over western Alaska and possibly into the
central and eastern Interior. Expect a strong storm with high
winds across the West Coast on Thursday and Friday, with
increasing chances for heavy precipitation in the Interior Friday
through Sunday. Models indicate an increasing probability for very
cold temperatures early next week behind this system.
Coastal Hazard Potential Days 3 and 4...None.
