Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 516 AM AKDT Fri Sep 17 2021

SYNOPSIS. The main theme going through the weekend is a transition to colder as Arctic air moves south across forecast area. This colder air is already moving into the northwest Arctic Coast as a front decays this morning. Chances for snow remain good across that region through the weekend. Quiet weather continues across the West Coast and Interior, but chances for snow in higher elevations possible east of Fairbanks tonight. A second surge of colder air Sunday night will be the next system to watch for snow chances going into next week for the Interior.

DISCUSSION. A relatively active pattern and a big transition from what is left of a seasonably pleasant fall to colder and increasing potential for snow in areas that haven't received snow this season in the Interior.

In the upper levels, the short term forecast will be dominated by an Arctic closed low that will dig southeast into the Chukchi Sea today and continue to move southeast near the northwest Arctic Coast by Saturday evening. This closed low will remain along the Arctic Coast going into next week.

The closed low is part of the longwave trough that will encompass the state that reaches into the Gulf of Alaska over the next several days. A strong shortwave from the Arctic closed low will move east across northern Alaska from now through Saturday night where it will reach the AlCan border. There will be another shortwave that will follow behind on Sunday, but will elongate from southwest to northeast across northern Alaska by Monday morning. A closed low in the Gulf of Alaska on Sunday night will begin to merge with this shortwave, but models differ to what degree these two features will phase going into Monday. Therefore, confidence is lower in how the weather will shape up for portions of the Interior by Sunday night.

At the surface, low pressure off the Arctic Coast is the main weather feature going through the weekend. A weather front is currently over the North Slope, bringing rain and snow to various areas from Utqiagvik west. As colder air moves in behind the front, snow showers expected to develop and persist along the northwest Arctic Coast going into tomorrow. The decaying front will reach the Interior by tomorrow morning.

A second front will move across the northwestern Arctic Coast bringing larger amounts of snow to that region going through the end of the weekend. As this front propagates to the southeast, the positioning between the models begin to differ going into Sunday night. As a result, conditions seem favorable for a more widespread possibility of snow, but the areas encompassed by these possibilities remain to be seen.

Central and Eastern Interior . Shaping up to be one more nice fall day before a transition to colder for the Interior. Northerly gap winds will setup this evening through Alaska Range passes with gusts to 35 mph as high pressure builds north of the Alaska Range. A weak weather front will slowly drift east across the Interior on Saturday, bringing chances for rain and snow east of Fairbanks. Otherwise, staying mostly dry until a second weather front moves through Sunday night. Models still differ on timing and location for the frontal setup, but looks to be a higher possibility of rain and snow across the region going into Monday.

North Slope and Brooks Range . Rain and snow continuing across the northwest Arctic Coast early this morning. Snow showers will be the main precipitation type going through the day as colder air will usher inland from the northwest. After a brief break Saturday afternoon, another weather front will bring the next round of snow to the northwest Arctic Coast by Saturday night. Larger snow accumulations of 4 to 6 inches are possible along the western Arctic Coast between Cape Lisburne and Point Lay going into next week. Snow across the Brooks Range will see anywhere from 1 to 3 inches through Saturday and an additional 4 to 6 inches from Saturday night through Sunday night. Temperatures looks to remain below normal going through the weekend.

West Coast and Western Interior . Chances for rain and snow increase for the Seward Peninsula, Kotzebue Sound, and eastern Norton Sound tonight as a weather front moves eastward. A second front will bring another round of rain and snow on Saturday night. Snow accumulations expected to be up to an inch for each round, but primarily limited to higher elevations of the Seward Peninsula and hills east of Norton Sound. Temperatures will dip below normal going into the weekend.

Coastal Hazard Potential Days 3 and 4 . None.

HYDROLOGY. No concerns at this time.
