Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 115 PM AKST Wed Nov 29 2023

SYNOPSIS

Light snow showers continue over the western Arctic and Upper Kobuk Valleys tonight. Blowing snow decreases late this afternoon on the Dalton Highway passes of the south-central Brooks Range. Dense fog is expected on parts of the Seward Peninsula tonight, and freezing fog on the Arctic Coast late tonight into Thursday night. Above normal temperatures through this weekend begin drop to near normal late this weekend and last into mid-next week.

DISCUSSION

Upper levels, analysis and model discussion...

High pressure into southern Canada extends a low to mid-level ridge into the East Interior and central North Slope this afternoon. A deeper low to mid-level trough over the Bering Sea persists. The shortwave trough in the western Arctic Coast this evening continues to move offshore into the southeastern Chukchi Sea tonight, while phasing with the Bering Sea low. That ridging breaks down and moves eastward tonight with open mid-level troughing over the Bering Sea lasts into tomorrow. A low lifts into the southeastern Bering Sea Friday evening and night, to then extend a front over the Yukon Delta Saturday.

Central and Eastern Interior...

Low to mid-level ridging over the central and eastern North Slope and Brooks Range keeps gusty winds over these areas through late this afternoon, then tapering by 6 PM AKST. For these decreasing wind speeds from 3-6 PM local time over the south-central Brooks Range, the Winter Weather Advisory remains in place only until 3 PM AKST as the reduced visibilities over the Dalton Highway passes increase this evening. The ridge slides eastward early tonight as troughing over the Chukchi Sea deepens a bit and moves eastward towards the northwest Arctic Coast by Midnight tonight. The result is a south to southwesterly flow backing to shore parallel to onshore flow by early Thursday. Expect freezing fog and heavy mist building onto the immediate Arctic Coast from west to east.
Visibility reductions are likely in these conditions through Friday morning.

West Coast and Western Interior...

Light snow showers continue over the Upper Kobuk Valley and near Kivalina/Red Dog mine as the shortwave trough lifting northward lasts into tonight over the western Arctic Coast. Less than 1 inch of additional snowfall would be expected from these late afternoon to evening showers today. Low level moisture sets up over the southern and eastern Seward Peninsula tonight and lasts into Thursday morning. Dense Fog headlines are in effect for those concerns of very limited visibility around 1/4 mile. Above normal temperatures through Sunday afternoon under weak stacked troughing.
The low pressure over the southern Bering Sea lifts another front into the Yukon Delta Saturday and brings a moderate chance of light snowfall to those locations into the southern part of Norton Sound.

North Slope and Brooks Range...

Residual light snow showers (resulting in an inch of additional snowfall) wrap up after Midnight tonight for the western and northwest Arctic Coast. Offshore southwesterly flow over the North Slope through this evening backs to easterly shore parallel to onshore flow on the Arctic Coast from Midnight to 03 AKST tonight. Expect increasing potential for freezing fog for north- central and northeast Arctic Coast locations into early Thursday morning and through Thursday midday.

Extended Forecast Days 4-7...

Weak West Coast troughing keeps off-and-on showery snowfall chances across the Yukon Delta and Seward Peninsula through Saturday, with most other locations remaining dry Friday and Saturday. Deep low pressure to the Gulf of Alaska and ridging over the Bering Sea begins to set up Sunday. East to northeast overland flow from the Arctic and northwest Canada moves into the area from northeast to southwest Saturday night into Sunday. This results in above-normal temperatures cooling to near normal for early to mid-next week.

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