Northern Alaska Forecast Discussion...CORRECTED National Weather Service Fairbanks AK 458 AM AKST Sun Dec 10 2023

SYNOPSIS
Snow squalls with periods of low visibility will ramp up again along the Bering Strait and Saint Lawrence Island on Monday and continue through Wednesday. The Interior will see cold temperatures this morning followed by an increased chance of snow and blowing snow mostly west and north of Fairbanks on Monday.
More snow possible Tuesday and Wednesday over the Interior. Winds will also increase over higher terrain on Monday. Heavy snow expected over the Eastern Alaska Range and strong winds in passes.

DISCUSSION

Aloft...
The long wave pattern consists of a deep trough over Alaska with a ridge over Western Canada and another ridge over Eastern Russia.
This pattern will remain stationary through the middle of next week. A series of short wave troughs will move north over Mainland Alaska through next week. This pattern will also cause persistent northerly flow over the Northern Bering Sea which will cause a band of lake affect type snow showers and squalls to persist from Point Hope to the Bering Strait to St Lawrence Is through next Wed.

West coast...Strong northerly winds will ramp back up on Monday through the Bering Strait and Saint Lawrence Island and continue into Wednesday. Sustained winds of 25 to 35 mph with gusts to 55 mph could lead to reduced visibiltiy to one half mile at times.
Strong winds and waves could also lead to heavy freezing spray which may create light ice accumulations on surfaces. These hazardous conditions are most likely for Little Diomede and Saint Lawerence Island.

North slope...The Arctic Coast has stratus, fog and flurries that will continue through the weekend. The area from Nuiqsut east will have light snow on Sat into Sun. Temps will cool to 10 below over the Arctic Coast. The Brooks range will see -20 to -30 below Monday and Tuesday. Strong winds will also develop in the Brooks range and cold wind chills to -50 below are possible on Monday night into Tuesday.

Interior...The Interior will cool to well below normal this weekend as conditions clear out, with temps falling into the 15 to 30 below range in clear areas of the Interior this morning.
Clouds could move over the area causing a slight warming of some surface temperatures around the Interior. A strong low will push inland over southern Alaska causing strong southeast winds to develop near Delta Junction and strong Northeast winds gusting to 40 mph over Elliott and Dalton Highway Summits Sun night into Monday along with blowing snow and low visibility.

A wind advisory has been issued for Delta Junction area. A special weather statement has been issued for the Interior. A Winter Storm warning has been issued for the eastern Alaska range for heavy snow late Sunday night through Tuesday morning.
Southerly winds will also increase through Alaska Range Passes Sun night then weaken on Monday. The Central Interior will be downsloped and not much snow expected on Monday, but north and west of Fairbanks will see 2 to 5 inches. The second shot of snow brings a better chance of accumulating snow for Fairbanks on Tuesday. Snow chances could linger into Wednesday for much of the Interior. There is still some uncertainity on amounts and timing of the snow Tuesday into Wednesday. Also temperatures will moderate above zero for much of the area for the first half of the week. A Winter Storm warning has been issued for the eastern Alaska range for heavy snow late Sunday night through Tuesday morning.

Coastal Hazard Potential Days 3 and 4...
Northerly gales will cause high waves from Point Hope to the Bering Strait to St Lawrence Island Mon through Wed. This combined with temperatures in the teens will cause freezing spray in the Bering Strait, at Diomede and Savoonga Sun night through Wed.
