Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 335 PM AKST Sun Feb 16 2020

SYNOPSIS. Light snow will diminish across the West Coast this evening. By late tonight however, a second storm system will move into the Y-K Delta, bringing heavy snow and gusty winds. Monday, this will move north, impacting the West Coast from the Seward Peninsula south, as well as the Yukon and lower Koyukuk valleys. This system will continue north and east through Tuesday, with gusty winds and by this point light to moderate snow. Strong south winds will cause difficult travel conditions across passes in the Alaska Range Monday and Tuesday.

DISCUSSION. Aloft at 500 mb . Ridging persists over the Interior with broad low pressure over the Bering Sea and eastern Russia. Sunday night into Monday, a stronger low pressure area will develop over the eastern Aleutians and track north into Bristol Bay. As this tracks north, the pressure gradient will tighten as the upper level system impacts the ridge still over the state. By late Tuesday, the GFS/NAM models have this low positioned over the Y-K Delta while the European model moves this low more quickly to the Seward Peninsula. Either way, the low will track to the north and weaken through mid-week. By Wednesday, the persistent northward track of the low will finally dislodge the broad high over the Interior, which will start to shift eastward. By Wednesday, there is quite a bit of variance between model guidance, but in general low pressure will be moving into the Aleutians and another low will be developing over either the Bering or the Chukchi Sea.

North Slope and Brooks Range . Even with a slight warming trend, temperatures will remain very cold on the North Slope through Monday. A weather front making its way up the West Coast will begin to impact the northwest Arctic coast Tuesday morning, bringing snow but warmer temperatures to the western Brooks Range and along the North Slope from Nuiqsut west as this system spreads northward through Wednesday. Snowfall amounts will likely be generally in the 1 to 3 inch range on both Tuesday and Wednesday. Gusty winds may be an issue with this system, with areas along the immediate coast and passes of the Brooks Range may see winds gusting to 30 or 35 mph as the front passes through. Blowing snow associated with this may necessitate a winter weather advisory along the northwest Arctic coast. Temperatures will fall to near seasonable temperatures again Thursday.

West Coast and western Interior . Snow is diminishing this evening along the West coast is diminishing this evening as the associated system weakens. The next system will impact the Y-K Delta early Monday, then track north up the coast into Tuesday. The initial round of snow will be heavy, and rapidly accumulating snow amounts as well as reduced visibility are likely in some areas. Storm total snowfall amounts will be 6 to 10 inches for much of the Yukon and Kuskokwim Valleys to the central and western Brooks Range. Much of the immediate coast will see around 3 to 6 inches through Wednesday. The Nulato Hills will likely see over a foot of snow with this storm. Winter Storm Warnings are in effect for the Yukon, Upper Kobuk, and Noatak Valleys. Winter Weather Advisories are in effect for much of the West Coast, and the advisory for St Lawrence Island and the Bering Strait coast has been upgraded to a Blizzard Warning, which is in effect until Tuesday morning.

Central and Eastern Interior . High pressure and an easterly gradient will support continued cold temperatures through early Monday. With the high pressure more entrenched along the Alcan border and easterly winds, wind chills will still be dangerously cold in zones 223 and 224 into Monday morning and Wind Chill Advisories are still in effect for those areas. Late Monday, a front associated with a Bering Sea low will move northeast from the Y-K Delta into the central Interior, bringing moderate to heavy snow as well as gusty winds. A winter weather advisory for snow and blowing snow is in effect for zone 219 with approximately 4 to 7 inches of snow expected Monday night through Tuesday. Additionally, strong southerly winds through the Alaska Range passes will be a concern Monday into Tuesday, with winds expected to gust from 70 to 80 mph through the Alaska Range passes. High Wind Warnings are in effect Monday afternoon through Tuesday evening.

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.
