Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 1044 AM AKDT Fri Sep 22 2023

SYNOPSIS
An arctic trough digging south and ridging building behind it means weather will be quiet for most of the Mainland with cooling temps. Fog will continue to be a concern each morning for the next several days.

DISCUSSION

Upper Levels and Analysis...
There is a closed 524 dam arctic low centered just offshore of Prudhoe Bay. There is a skinny 544 dam ridge axis over the W Interior and West Coast. There is a 526 dam upper low over the N Bering Sea with an elongated deformation zone stretching from Saint Lawrence Island to the Gulf of AK. There are some convective showers over the Norton Sound area with areas of fog and low stratus over the E Interior to Fairbanks and down the Tanana River Valley.

Model Discussion...
There are no notable discrepancies in the models. Forecast confidence is high with minimal notable weather impacts in the near future. The NAM nest and NAM12 were favored models.

Central and Eastern Interior...
An arctic trough is digging south over the E Interior. The front will bring a mix of rain and snow showers over the E Interior and higher terrain mountains through Sat night. Light north winds will accompany this front, with partly clearing skies Saturday lasting through Monday. Areas of morning fog will be pervasive, especially near river valleys.

West Coast and Western Interior...
Unusually quiet weather will persist with light offshore winds and high pressure aloft building in. Expect morning fog threats especially near river valleys for the next several days. Mixed rain and snow showers will be possible around Norton Sound the next couple days.

North Slope and Brooks Range...
An arctic low will continue to bring northwest to westerly winds along the arctic coast through Sat night before weak high pressure builds in. Snow showers will continue on and off into Sunday, with light accumulations up to 2 inches over the higher terrain from Anaktuvuk Pass eastward. Expect north winds 15 to 25 mph through Atigun Pass as the front crosses over the Brooks Range tonight and Saturday.

Extended Forecast Days 4-7...
Mainland high pressure aloft will gradually weaken next week, but it will generally be on the drier side with only minor threats for precipitation. No significant storms or large temperature anomalies are expected in the near future.

Coastal Hazard Potential Days 3 and 4...None.
