Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 322 PM AKST Mon Nov 30 2020

SYNOPSIS. An active weather pattern is in place across the region as the upper level flow amplifies. A cold arctic trough is digging across the West Coast and a very strong warm front is moving into the Gulf of Alaska. This will setup locally heavy snow over the Western Interior with chinook warming over the Eastern Interior. This warming will be preceded by a quick shot of snow tomorrow along with some blowing and drifting concerns over highway summits. The chinook warming will also support hurricane force winds in the Alaska Range gaps such as Isabel Pass and Windy Pass near Denali. Up north, a tightening pressure gradient will allow for gale force easterly winds and areas of blowing and drifting snow.

DISCUSSION.

Upper Levels and Analysis . A rather impressive 496 dam cold arctic trough is digging across the West Coast and Western Interior as a powerful North Pacific low pushes a strong warm front into the Gulf of Alaska. This is leading to rapid amplification of the upper level pattern as the flow becomes increasingly southerly over the Eastern Interior in response to the warm air advection overspreading the Gulf Coast. Gap winds in the Alaska Range are already on the upward trend in response to the cross-barrier flow increasing. Over the West Coast, strong gale force northerly winds continue along with periodic snow squalls over the capes and Saint Lawrence Island. Over the North Slope, light snow showers continue in association with the arctic trough which has setup shop over the West Coast. East winds are already on the ramp up resulting in some blowing and drifting snow.

Central and Eastern Interior . The pattern is shifting to a chinook pattern as a strong warm front moves into the Gulf of Alaska. Winds in the AK Range gaps are already pushing 45 mph, and they will continue to increase to hurricane force this evening and overnight. A warm front aloft pushes through the Interior late tonight and tomorrow, bringing a quick shot of snow, heaviest from the White Mountains north. This will be accompanied by breezy northeast winds across the Hills with blowing and drifting concerns. There is an outside shot of mixed precip, as well, but this front looks like mostly snow as it will be prefrontal precipitation. The front clears by tomorrow late morning, and the remainder of Tuesday and early Wednesday will be mostly dry with temps rising to near 32 if not higher across higher elevations. The one exception will be the upper Koyukuk Valley which will see periods of moderate snow, with accumulations of 4-8" from Allakaket west. The cold front will begin shifting east Wednesday with quickly falling temps over the Central Interior and developing snowfall. Snowfall will move into the Tanana Valley by Wednesday night, and will linger into Thursday before the front falls apart.

West Coast and Western Interior . Strong gale force northerly winds will continue over the Bering Strait as an arctic trough remains over the region. More snow will be the main story for this forecast as a warm front from the North Pacific spreads in moisture northward. The general thinking is periods of snow will bring 4-8" of snow over the Interior, heaviest mainly east of Galena to Mcgrath to Ambler/Shungnak. Snow will begin to taper off Wednesday night and Thursday.

North Slope and Brooks Range . Light snow and blowing snow will be the main concern over the Arctic Coast as an arctic trough sets up over the western half, and very strong 35-55 mph winds develop over the eastern half, bringing areas of significant blowing and drifting snow. Winter Weather advisories have been issued for the eastern arctic for widespread blowing and drifting snow until the gradient relaxes and winds come down on Tuesday evening. Otherwise, expect periods of light snow fall to continue on and off as the trough shifts east and colder air filters eastward through Thursday.

Coastal Hazard Potential Days 3 and 4 . None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
