Marine Weather and Tide Forecast for Kokhanok, AK

.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3)...

Currently, mid to low stratus linger across areas east of the Pribs and across the Southwest Mainland, including the Alaska Peninsula. To the west, the unseasonably strong North Pacific low we've been speaking to the last few days has moved north, with its low center now located between Attu Island and Adak - its cloud shield covering the western Bering, as far northeast as the Pribilof Islands. Gusts 50 to 60 mph will not be uncommon for the next 36 hours from Atka west and across the western Bering as the low moves north before losing some of its core strength. Shemya will receive the strongest winds, which are expected to gust up to 70 mph for a short period this evening. Precipitation may start as mixed before transitioning to all rain as warm air advection moves in. The low will slowly move east over the weekend. The leading front will bring a potential for blowing snow across the Pribilof Islands overnight tonight and the Aleutian Chain Saturday through early Sunday, before temperatures warm. The leading front will progress rapidly east bringing blowing snow conditions to the Kuskokwim Delta Saturday and Sunday as the front pushes inland. Winter weather products have been issued across the Delta for reduced visibilities in blowing snow over the period.

Despite the warm air advection in front of the low, cold air will wrap around the back of the low, allowing for higher instability and showery precipitation to form over the Bering as the low moves east. Looking ahead to next week, an Arctic trough dips into Southwest Alaska, potentially dropping low temperatures into the teens and single digits across the Southwest Mainland beginning Monday night. These temperatures combined with lingering precipitation from the strong low means widespread snowfall is possible Monday onward.

.LONG TERM FORECAST (Days 4 through 7: Tuesday through Friday)...

A shift toward cooler and more unsettled weather is expected across much of Alaska through the upcoming week. A pattern dropping in from the north will bring colder air along with periods of snow showers across the interior and Alaska Range.

Meanwhile, a weakening but still impactful storm over the southern Bering sea will continue to create hazardous marine conditions, including gusty winds and steady precipitation across the Aleutians, Alaska Peninsula, and Southwest Alaska.

By early to mid next week, attention turns to Southcentral and Southeast Alaska as a developing system pulls in a deep surge of moisture. This will likely bring several days of rain and snow, with heavier snow totals possible across the Alaska Range and through higher elevation passes, along with increasing winds.

There is also a strong North Pacific low being monitored. While current projections keep it south of the state, any northward shift toward the Gulf of Alaska could lead to another round of impactful weather late next week.
