Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 127 PM AKST Wed Jan 27 2021

SYNOPSIS. A weather front associated with a strong low in the Bering Sea will impact the southwest coast today, bringing light snow and gusty winds to the region. Impacts are expected to be minimal for most areas, though St. Lawrence Island is experiencing blizzard conditions due to high winds and blowing snow. Snow will gradually move inland tonight into Thursday, with light accumulation expected for portions of the Interior. Areas with snow and cloud cover will see near average temperatures, but cold is expected to make a return late in the weekend into early next week.

DISCUSSION.

Aloft 500 mb . A very busy synoptic pattern will feature the interaction of several systems, which will have a significant impact on the forecast, particularly late in the weekend. A high amplitude ridge extending from the north Pacific, across the Western interior of Alaska, and into the Siberian Arctic is being effectively cut in half. A deep longwave trough anchored by a 501 dam height minima in the central Bering Sea will progress east as an Arctic trough swings down from the Beaufort Sea. The energy from this Arctic system will amplify the Bering trough and effectively cut off the high pressure in the Siberian Arctic. Deep longwave troughing will progress east to encompass much of the state by Friday. A second high amplitude ridge will move into the eastern Bering Sea Sunday. The forecast beyond this point becomes tricky as several height minima swirling about in the Beaufort sea will interact with the ridge and cause the longwave pattern to further amplify. Placement and strength of these features will determine exactly how cold temperatures will get early in the week.

Models . Again, there are no major discrepancies in guidance through Sunday, but the aforementioned interaction of the next ridge and Arctic lows will dictate the weather later this weekend. ECMWF and GFS solutions seem to have met in the middle compared to their previous runs, though the GFS still keeps the Arctic low closed off and fairly deep at 507 dam over the lower Yukon Valley Monday. This would produce weak southerly flow over the central and eastern Interior and help moderate temperatures somewhat. The ECMWF merges the low into the longwave trough much more quickly, causing it to further amplify southward. This would support weak flow over the Interior and the intrusion of colder air. The Canadian model takes this to the extreme and supports a very deep persistent Arctic troughing pattern throughout the week. We will continue to lean in the direction of the ECMWF, as this has been somewhat consistent and still the middle ground solution with regard to extreme temperatures.

North Slope and Brooks Range . A weak surface low over the Mackenzie Delta will continue to support light east winds along with broken cloud cover and a few flurries for much of the North Slope. Weather will remain generally benign over the next few days, though expect a gradual increase in northeast as deep low pressure moves into the eastern Bering Sea. Temperatures will assume a steady drop going into the weekend, with some of the coldest temperatures of the year to follow early next week.

West Coast and Western Interior . A strong weather front associated with a 969 mb low situated roughly 350 nm southwest of St. Matthew Island is tracking onshore this afternoon, impacting the Y-K Delta and St. Lawrence Island. Strong winds up to 50 mph on St. Lawrence Island combined with heavy snow at times is resulting in blizzard conditions, so a Blizzard Warning is in effect through midnight. The front will continue to push inland and weaken. Light snow will persist through Friday and taper off into the weekend. Total accumulations of 1 to 3 inches are expected for much of the region south of the Bering Strait to Ambler. Elevated areas of the Kuskokwim Range could see up to 6 inches locally though Saturday. Frigid temperatures are expected to follow beginning Sunday as Arctic air spills southward.

Central and Eastern Interior . Below average temperatures will persist today and this evening, but will begin to moderate late tonight and Thursday as clouds and light snow associated with the aforementioned front moves east out of the Western Interior. Light snow will accompany the front as it tracks north of the Alaska Range late Thursday into Friday, though accumulations will be minimal due to weak southerly flow aloft. Expect seasonal temperatures through the weekend but a return to below normal temperatures are expected across much of the Interior early next week.

Coastal Hazard Potential Days 3 and 4 . None.

AFG WATCHES/WARNINGS/ADVISORIES. Blizzard Warning for AKZ213.

Gale Warning for PKZ210.

Brisk Wind Advisory for PKZ200-PKZ220-PKZ225.
