Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 554 AM AKST Sun Mar 7 2021

SYNOPSIS . Very impressive storm moving to the coast will bring Blizzard conditions to most coastal areas today with winds gusting to 70 mph on the outer Capes. The strong winds and possible Blizzard conditions will push inland into the Upper Kobuk and Noatak tonight, and north into the Arctic areas from Utqiagvik west. Snowfall amounts up to 16 inches are possible in the mountains and Nulato hills. Stratus in the Interior will produce some flurries or a period of light snow with no significant accumulation into the afternoon before the stratus breaks up.

DISCUSSION.

Models . The 07/00Z solutions continue the good run to run continuity through the short term that we have been seeing the last several days. No significant differences between the surface solutions and the 07/06Z analysis. Winds appear to be a bit stronger with this system, much like the last system that moved to the West Coast so will make some adjustments to accommodate that. Precipitation amounts are similar and so is the timing so will lean on a general blend of the solutions which will mot make any significant changes to the current database.

Aloft . At 500 hpa . A decaying trough is moving through the Eastern Interior this morning as ridging builds north over the West Coast and Western Interior. A 506 dam low remains just south of Banks Island, while the low that was near Wrangel Island yesterday has moved to around 500 nm west of it this morning with the troughing extending north of Wrangel Island over Utqiagvik to Arctic Village to Delta Junction to Valdez. Ridging that was over the state yesterday has weakened, but hanging on over the AlCan while the high has moved to 800 nm north of Deadhorse. Ridging continues to build north today as it moves to lie over Kodiak Island to Tanana then north over 150W by Monday morning. A 482 dam low near the Northern Kamchatka Peninsula will move north over Chukotka as height fall to 478 dam with a very strong south flow developing over the Central and Eastern Bering Sea, and Western Arctic. The ridging over the state will slowly slide east over the AlCan Border and Beaufort Sea by Tuesday morning while the low love over Chukotka will move over the New Siberian Island as another low develops over Kamchatka and moves just north of the Gulf of Anadyr by Tuesday morning at 485 dam. A wave moving around the low will move to the Bering Strait Tuesday, then across the state Wednesday At 850 hpa. A strong push of warm air in advance of the front to the west will push a few pockets of temperatures around 0C north into the Western Interior today. The warm air will slowly moderate as slide east as the low to the west pushes the ridging east. A strong push of cold air over the Arctic will move over the West Coast and Arctic Wednesday night with the -20C isotherm lying from Deadhorse to Dillingham, then northwest over St Matthew Island Wednesday night.

Surface . Very strong front associated with a 965 mb low that will move to the Gulf of Anadyr today has moved to St Lawrence Island and will move to the West Coast today and the Northwest Arctic Coast tonight. Widespread Blizzard conditions with heavy snow expected today and tonight. Very tight pressure gradient on the West Coast and the adjacent waters will produce winds gusting to 70 mph on the outer Capes and 50 mph in the remainder of the coastal areas today and tonight. High pressure is building in the Interior today with a 1023 mb high in the Middle Tanana Valley and a 1021 mb high in the Middle Koyukuk Valley, and high pressure extending southwest across Bristol Bay. By Monday morning the high pressure will be holding on over the Central and Eastern Interior with leeside troughing developing north of the ranges. A 1029 mb high will develop over the Copper River Basin and that will help tighten the gradient across the Alaska Range as strong south winds gusting near 60 mph develop Monday morning. A 1030 mb high will develop in the Upper Yukon Flats and that will tighten the gradient across the Eastern Brooks Range with south winds gusting around 45 mph developing. Out west a 988 mb low will develop along the front and move to St Lawrence Island Monday morning and Kotzebue Sound Monday afternoon. As the front moves inland it will weaken and the leeside troughing will weaken Tuesday morning with the winds diminishing.

Arctic Coast and Brooks Range . Front moving to the West Coast today will move into the area west of Utqiagvik late this after and evening. Strong winds will develop with blowing snow reducing visibility to less than one half mile at times. Winds will be gusting to around 50 mph so Winter Storm Warnings are in effect. The winds will work their way east increasing in the Brooks Range, and around Deadhorse tonight so Winter Weather Advisories are in effect for those areas. Blowing and drifting snow will make travel difficult across the area through at least Monday. Temperatures warmer.

West Coast and Western Interior . Blizzard and Winter Storm warning continue in all the coastal areas and some Interior locations with Winter Storm watches for the remainder of the area. Winds increasing sharply this morning with gusts to 70 mph expected on the outer Capes. Most coastal locations will have winds gusting around 50 mph. Snow, and blowing and drifting snow, will reduce visibility to near zero at times making travel extremely difficult through at least Tuesday morning. Snowfall amounts will range up to 16 inches with the heaviest amounts along the Western Brooks Range, the mountains on the Seward Peninsula, and in the Nulato Hills. Conditions improving through the day Tuesday. Temperatures warming through Monday, then cooling Tuesday as cold air wraps around the low over the area.

Central and Eastern Interior . Stratus on the satellite does not look like it will be moving anytime soon as it extends west to the coast. Some flurries into the afternoon, then some clearing this evening. No significant snow is expected. Winds generally light and variable, but they will be increasing Monday morning in the Alaska range with south winds gusting around 60 mph near the passes. Temperatures will be slightly warmer the next couple days with highs in the 20s and 30s and lows in the single digits above and below.

Coastal Hazard Potential Days 3 and 4 . None.

Extended forecast for days 4 to 7 . The pattern will become less active late in the week as high pressure builds over mainland Alaska, then slowly slides east over the Yukon Territory. As the high pressure builds over the area cold air will push southeast across the state with temperatures cooling through Saturday before they rebound. Temperatures will be 10 to 15 degrees below climatological normals as they fall into the teens and 20s below, while highs highs will range from around 10 below to 10 above.
