Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 504 AM AKDT Mon Oct 18 2021

SYNOPSIS. Strong low moving to St Lawrence Island will be primary influence for most of the forecast area through Wednesday. Weather front will bring snow to St Lawrence Island today, and the Lower Yukon Delta tonight. Snow will spread north to the Bering Strait on Tuesday. Warming temperatures will bring a mix of rain and snow to areas south of Nome Tuesday. Strong pressure gradients developing in the Interior and Arctic will bring strong gusty winds locally. Winds gusting around 60 mph on St Lawrence Island this evening as the front moves to the coast. Winds will diminish as the front gets to the mainland. Strong gradient across the Alaska range will produce strong gusty gap winds, and the Tanana Valley Jet will set up as high pressure pushes west into the Upper Tanana Valley. Winds will be gusting to around 60 near the Alaska Range Passes, and around 50 mph in the Delta Junction area Tuesday. Strong east winds developing in the Arctic will bring blowing and drifting snow that may impact visibility and travel in the area. Temperatures will be warming slowly the next few days.

DISCUSSION.

Models . The 18/00Z solutions are in good agreement in the near term, but are struggling with the gap winds and Tanana Valley Jet winds. The NAM is an outlier with precipitation and timing with the next system and a wave moving into the Interior Tuesday. Solution winds are a bit stronger aloft with the south flow across the Alaska Range so will increase the gap winds, and decrease the Tanana Valley Jet winds as they battle it out for the same space around Delta Junction. Surface solutions initialized well against the 18/06Z local analysis. Will only be making some minor adjustment to the current forecast database to address the issues noted above.

Aloft . At 500 hpa . Weak ridging across the southern half of mainland Alaska as a 516 dam low has moved to 300 nm south of Seward, while low over the Arctic has merged with a 505 dam low 400 nm west of Wrangel Island with troughing extending east over 74N. A 500 dam low has moved over the Northwest Bering Sea. Sunday afternoon the ridging will be hanging on over the Gulf of Alaska Coast as the low continue to move southeast to 600 nm south of Prince William Sound. The low in the Siberian Arctic will be quasi stationary with a shortwave moving over the Northwest Arctic Coast to lie over Wainwright to Anaktuvuk Pass as it moves through the flow. The low over the Bering Sea will move to 400 nm west of St Matthew Island with a trough lying from the low to just west of St Matthew Island then southwest over the Central Arctic. A ridge axis will enhance and lie from Galena over the Western Chukchi Sea and Northern Chukotka. Tuesday morning ridging will push west over the Southeast Interior and come into phase with the ridging over the Northwest Mainland with the axis extending west over Wrangel Island. The low in the Siberian Arctic will move north and the trough axis will slide north of 77N. The shortwave moving through the flow will move over the Beaufort Sea. The low over the Bering Sea will move to 100 nm west of St Matthew Island with the shortwave moving to lie from the low over St Lawrence Island to Nunivak Island to Cold Bay. The low south of Prince William Sound will start filling and move north over the Gulf of Alaska at 525 dam, then merge with the low over the Bering Sea by Tuesday afternoon. A shortwave associated with the filling low will move over the Alaska Range Tuesday evening and over the Interior by Wednesday morning At 850 hpa. -10C isotherm lies from Old Crow YT to Huslia to Gambell, and will move north to lie over the Brooks Range by Tuesday morning. A dome of warm air around 0C will move over the Central and Eastern Interior south of the Yukon River by Tuesday morning. The -10C isotherm will move north of the Arctic Coast Tuesday evening as warmer air near 0C is pushed north to the Eastern Arctic Coast.

Surface . A 977 mb low is just southwest of Kodiak City this morning with a trough extending north to the Alaska Range, then northeast. A front associated with the low is moving east across the Northeast Pacific. Leeside troughing north of the Alaska Range is weakening. A 1006 mb low is in MacKenzie Bay, with troughing extending northwest to a 1006 mb low 400 nm northwest of Utqiagvik. A cold front extending from the low extends southeast to Prudhoe Bay, then southwest over Bettles. A 1016 mb high has moved over the Western Brooks Range with high pressure extending west over the Chukchi Sea, and southwest over the Bering Strait and the Pribilofs to a high in the Central Pacific. A strong 970 mb low has moved to the Northwest Bering Sea with a front extending east to the Dateline, then south to the remnants of Tropical Depression (TD) Namtheun 600 nm south of Attu. Monday afternoon the weak low pressure will extend from the southern Beaufort Sea northwest to a 1002 mb low in the Siberian Arctic, a 1014 mb high will be near Utqiagvik, weak troughing will extend east between the ranges, the low in the Bering Sea will move to 400 nm west of St Matthew Island at 975 mb. The front will move to lie from the low to St Matthew Island to Adak, while the remnants of TD Namtheun will be 500 nm south of Adak. Broad area of low pressure will hold over the Northeast Pacific. High pressure will be pushing in from the east into the Upper Tanana Valley. Tuesday morning low pressure will be across much of the state as the low in the Bering Sea moves to 150 nm northwest of St Matthew Island with the front moving to lie over St Lawrence Island to Nunivak Island to Cold Bay then south to the remnants of TD Namtheun 400 nm south of Nikolski. High pressure on the Arctic Coast will slide over the offshore waters. As the low pressure presses to the east and high pressure pushes into the Upper Tanana Valley the pressure gradient will tighten and the Tanana Valley Jet will kick in with strong gusty winds developing. The gradient will also tighten across the Alaska Range with strong gusty gap winds developing near the passes. Leeside troughing developing north of the Brooks Range Tuesday will combing with high pressure over the Arctic and pushing west over the south slopes of the Brooks Range to produce strong gusty winds across the area.

Arctic Coast and Brooks Range . Generally cloudy, but a few breaks are possible today and tonight as the weather front pulls out to the northeast. Light snow or flurries mainly east of Utqiagvik today will taper off. Patchy fog. Along the coast highs will be in the 20s, with lows in the teens. Inland and in the Brooks Range highs in the lower teens and lows in the single digits above. Low pressure pushing into the area from the west will combine with high pressure over the Arctic and high pressure pushing west over the south slopes of the Eastern Brooks Range to produce strong gusty winds across the area Tuesday with areas of blowing snow.

West Coast and Western Interior . High pressure in the Chukchi Sea extends south through the Bering Strait and across the Pribilof Island to the North Pacific will slide over mainland Alaska this morning as the strong low in the Bering Sea moves east. Weather front will bring snow to St Lawrence Island this afternoon, and to the Lower Yukon Delta tonight. Snow will spread up the coast to the Bering Strait Tuesday as snow mixes with rain in the Lower Yukon Delta Tuesday afternoon. Snow will move into the Middle Yukon Valley Tuesday night. Snowfall amounts will generally be less than 4 inches. Winds on St Lawrence Island increasing this morning to southeast at 20 to 35 mph gusting 45 mph. Winds on St Lawrence Island gusting to 55 mph this evening. Winds variable to 10 mph this morning along the coast and inland. Strong winds will spread east tonight south of the Bering Strait, but diminish as they approach the coast, but still be gusting near 40 mph on the Bering Strait coast and in Norton Sound. Today highs in the mid 20s to mid 30s, with lows in the teens to mid 20s. Tuesday warming temperatures will push highs from the Seward Peninsula south pushing into the upper 30s and lower 40s, while lows will be in the upper 20s to mid 30s.

Central and Eastern Interior . Quiet across the Interior with high clouds slowly moving out of the area as weak high pressure moves in. Winds kicking up with the Tanana Valley Jet setting up Tuesday so look for winds gusting near 50 mph around Delta Junction. Gap winds also setting up for Tuesday with the strongest winds kicking in from the Parks Highway west, spreading east Tuesday night. Gap winds will be gusting near 60 mph Tuesday. Lows 10 to 20 above with highs in the mid 20s to mid 30s. Warmer temperatures through the week.

Coastal Hazard Potential Days 3 and 4 . Elevated surf on the outer coastlines through the week with wave runup 1 to 2 feet above the normal high tide line.

Extended forecast for days 4 to 7 . A low near St Lawrence Island will weakens with broad low pressure over most of the mainland and the Arctic nearshore waters. A strong low will move into the southwestern Bering Sea Wednesday night and to the Pribilofs Thursday evening while high pressure builds over the Eastern Interior. Precipitation generally limited to the Lower Yukon Delta and St Lawrence Island. Temperatures will be slightly above climatological normals.
