Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 305 PM AKST Mon Dec 6 2021

SYNOPSIS. A winter storm continues across parts of the state as the associated front is moving inland, with heavy snow over parts of the Interior, as well as the Alaska Range and Brooks Range. High water over parts of the YK Delta and Norton Sound are receding, but remain elevated. The associated low will drift into the Chukchi Sea, and is expected to bring elevated water and possibly some ice push from Point Lay to Point Barrow. Light snow will move back into the Eastern Interior tomorrow as the cold front moves east.

DISCUSSION.

Upper Levels and Analysis . There is a 492 dam 500 hpa closed low just a little north of Point Hope. The surface low is analyzed around 965 mb based on obs around the Lisburne Peninsula. A strong pressure gradient persists across the Brooks Range and Alaska Range, with south winds through the AK Range continuing to blast to near hurricane force through Isabel Pass. A cold front/deformation zone aloft sits over the Western Interior, with a secondary basal shortwave supporting a strong surface low which is moving up towards Cook Inlet. Temps have moderated greatly over the Interior with the strong south winds importing much warmer air, as temps in Fairbanks have shot up into the 20s, a full 60 degrees warmer from a few days ago.

Model Discussion . The numerical models are in very good agreement overall, although they are still wobbling back and forth with the low currently near Point Hope drifting into the Chukchi Sea. The current track is to stall the low northwest of Point Barrow, which means there will be some elevated water levels and high surf potential, especially now that the shorefast ice has mostly broken free. The NAM hi-res was favored which captures the strong gap winds as well as the coastal winds over the Chukchi.

Central and Eastern Interior . Heavy snow and significant blowing snow continues through Isabel Pass of the Eastern Alaska Range. Heavy snow also continues over the Upper Koyukuk Valley and southern Brooks Range, where there have been reports of very heavy snowfall with the moist south flow. Downslope flow has kept most of the Interior dry, and also much warmer, with the current temp at Fairbanks airport of 27 F as of noon. A vigorous cold front from the West Coast storm moves east tonight, and will bring accumulating snow to pretty much all of the Interior, along with a switch from south to north winds through Isabel/Windy Passes. Expect north winds tomorrow to peak around 30-45 mph south of Black Rapids, which will likely result in significant blowing and drifting snow concerns, so travelers should prepare for this significant hazard. Elsewhere, generally expecting 1-3" snow through Tuesday with possible snow squalls as the cold front shifts through, with flurries lingering through Wed. Expect blowing and drifting snow concerns with northwest winds from Dot Lake to Tok, tomorrow afternoon and evening. More light snow will move into the Interior Wed night and Thu.

West Coast and Western Interior . The worst of the storm is over as winds are diminishing, snow is tapering off, and water levels over the YK Delta to Norton Sound are dropping. Water levels are also peaking across the NW Arctic, with Red Dog Dock at near 4 feet above MHHW according to that tide gage. Water levels rapidly drop off everywhere tonight as the low moves into the Chukchi Sea and the low weakens. Snow showers will, however, move back into the West Coast and Interior as the front surges inland tonight, with light accumulations possible, especially from the Seward Peninsula northward where 1-2" is expected. The next front will bring in snow and blowing snow to the YK Delta through the Middle Yukon with 2-4" snow Tue night through Wed night.

North Slope and Brooks Range . Snow and blowing snow will ramp up over the western Arctic as the surface low associated with the strong West Coast storm tracks into the Chukchi Sea, bringing blustery southwest winds 25 to 35 mph. This will also bring elevated water levels and high surf, thus a high surf advisory will be in effect from Point Lay to Point Barrow, with 1-3 feet above MHHW expected. Elsewhere, the strong south gradient weakens tonight, with light snow spreading from across the eastern Arctic Tue into Wed, some some blowing and drifting snow east of Prudhoe Bay with a brief burst of west winds.

Coastal Hazard Potential Days 3 and 4 . Water levels have peaked and are already dropping pretty much everywhere along the West Coast and Saint Lawrence. However, as the low drifts north of Point Hope, southwest winds will push water levels 1-3 feet above MHHW from Point Lay to Point Barrow. With a lack of ice, this may create some high surf and possibly some free ice to move onshore.

Extended Forecast Days 4-7 . A strong low moving from Bristol Bay to the Gulf of Alaska on Thu through Sat will draw down colder air over the Interior but will also increase snow chances across the Southern and Eastern Interior. 850 temps will be well below average with values into the -20 to -30C range, which should allow for another cold period before the next possible front moves into the SW part of the state late weekend/early next week.
