Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 1254 PM AKDT Thu Apr 15 2021

SYNOPSIS. High pressure building over Alaska through the weekend and into early next week will bring warm and dry conditions to most of Northern Alaska into early next week. The exception to this will be the of the Northwest Coast where strong winds, and blowing snow are expected Friday. High temperatures in the Southern Interior are expected to reach into the lower 60s by early next week and will continue to ripen and produce runoff from snow melt at lower elevations over much of the Interior.

DISCUSSION. Models . The 15/12z model suite initialized well against the 12z observational data and verified well against the 18z observational data. The 15/12z model suite remains consistent with previous model runs in producing a strong blocking high pressure system over Alaska beginning late Friday and continuing into early next week and there is limited model spread from model family to model family in both the near term as well as the mid range forecasts. Difference between model families emerge across the suite of models by the middle of next week.

Aloft . The current long wave pattern consists of a ridge over Western Canada and the Eastern Pacific, a trough over Alaska and the Western Gulf of Alaska, and another ridge over the Bering Sea. The ridge over the Bering Sea will build east over Mainland Alaska tonight and Fri. By the weekend the pattern will consist of a strong ridge over Western Canada and Mainland Alaska, and a trough over the Bering Sea and Western Gulf of Alaska that will persist into early next week. What this means is that the areas of light snow and rain associate with the weakening trough over the Interior will taper off tonight, then skies clearing and little if any precip over Northern Alaska from Fri night into the weekend under the ridge aloft. Additionally, the building ridge will cause sunny skies and well above normal temperatures over all of Northern Alaska this weekend into next week.

Surface . An weak occluded front stretches from near McGrath to Arctic Village to a 1018 mb low near Inuvik will continue to weaken as it moves east over the Central and Eastern Interior tonight and Friday. Light rain and snow showers associated with this front will continue to taper off tonight.

High pressure over the Bering and Chukchi Seas will continue to build over the North Slope and Western Coast this evening, and over the Interior on Fri. This will bring clearing skies most areas, but will see areas of nocturnal fog dense at times along the Norton Sound Coast this evening into Friday. Dense Fog headlines have been issued for these areas.

A warm front in the Western Bering Sea will move along the West Coast Fri AM, and over the Western Arctic Coast Fri PM, and to the Eastern Arctic Coast Sat AM. This will bring fog and a slight chance of rain to the West Coast Fri, and to the Western Arctic Fri PM. This will bring SW winds 15-25 kt to the West Coast Fri into Sat, and SW wind 25-35 kt to the Western Arctic Coast Fri PM Fri and Fri night with the strongest winds, and with gusts to 45 kt. from Cape Lisburne to Point Lay. Reduced visibility in blowing snow may occur in areas that receive the strongest winds and where the snowpack has not been glazed by the strong April sun.

Coastal Hazard Potential Days 3 and 4 . None.

FIRE WEATHER. None.

HYDROLOGY. Snow pack will continue to ripen south of the Brooks Range, with significant melting beginning in the Interior next week.

AFG WATCHES/WARNINGS/ADVISORIES. Gale Warning for PKZ220-PKZ225-PKZ230.

Brisk Wind Advisory for PKZ210-PKZ235.
