Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 245 PM AKST Fri Jan 15 2021

SYNOPSIS. Another day, more southerly flow. That is the name of this game for most of this winter for much of the Interior. This continues to promote moderate easterly gradients up along the North Slope and north winds through the Bering Strait and Norton Sound. Another weakening front is lifting northward, bringing light snow to areas north of the Tanana Valley. Weather will remain mostly above average temperature wise for the Interior with light snow threats continuing for the West Coast. Gap winds in the AK Range and the Tanana Valley jet will continue to blow, as well.

DISCUSSION.

Upper Levels and Analysis . An elongated shortwave trough is moving north through the Interior with a weak shortwave ridge ahead of it, over the West Coast. There is a 513 dam at 500 hpa arctic trough over the North Slope, and this is supporting the coldest airmass over the state. Otherwise, the northerly pressure gradient over the Bering Strait continues as low after low plows into the Gulf of AK with a persistent easterly gradient over the North Slope.

Model Discussion . Models are in very good agreement with the general pattern through early next week. The biggest discrepancy is associated with the placement of an inverted trough which will form over the West Coast Sunday and Monday. The GFS is the farthest west while every other model favors the immediate West Coast, which brings snow threats to the entire West Coast and parts of the Western Interior. This blend was favored with the GFS thrown out after today.

Central and Eastern Interior . A band of light snow north of the Tanana Valley will continue to move north then fall apart by tomorrow morning. Accumulations will be minimal. More southerly flow will develop with warming temps as 850 hpa temps (around 4000-5000 feet) rise to near 0 Celsius across parts of the Interior this weekend. Strong gap winds will also continue over the AK Range with a persistent Tanana Valley jet. A strong low moving into the Gulf of Alaska will induce another strong gradient with increasing northeast winds and a strong Tanana Valley Jet. Ak Range gaps will also likely blow into the 60 mph range Sunday evening and night. Snow and wintry mix of precipitation increases late Monday as the gulf low moves a strong front inland.

West Coast and Western Interior . North winds will continue to remain blustery along the coast with areas of blowing and drifting snow. A band of light snow will move over the West Coast from the Interior tonight and then fall apart tomorrow. An inverted trough will develop over the YK Delta Sunday morning and lift north, bringing a band of accumulating snow much of the West Coast and Interior through Monday.

North Slope and Brooks Range . Moderate easterly winds will continue through tomorrow then begin to wave over the Eastern Arctic Saturday night. The strongest gradient and winds will remain over the Western Arctic but will only impact the immediate coast from Point Lay west. A band of light snow will move over the Brooks Range this evening and tonight then fall apart as it crosses to the coast. Snow amounts will be minimal. Otherwise, periods of blowing and drifting snow will continue through the next three days.

Extended Forecast Days 4-7 . The extended forecast looks rather interesting as a series of storms looks poised to impact the West Coast with increasing threats for Interior snow, as well. The culprit will be a retrogression of the upper high which has been dominant over the Interior for weeks shifting back to the Bering Sea. There is high confidence the pattern will shift but still a lot uncertainty in exactly how it will all play out Stay tuned.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
