Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 502 AM AKDT Tue Jun 25 2024

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...

Discussion:

The main weather features in play throughout the remainder of the workweek will be a North Pacific low moving northwards over the western Aleutians into the Bering Sea today before rapidly deepening, and a broad and elongated ridge extending from central Alaska down into British Columbia. In between these features, an area of low pressure continues to weaken near Kodiak Island. Several easterly waves will traverse the periphery of the ridge before the upper ridge axis shifts north in response to the Bering low lifting a front up across the AKPen and western Gulf. This front looks to stall near Kodiak Island then quickly wash out by Friday. Kodiak will see some rain as the front nears the island, but rain looks to remain light and mainly confined to the southern half of the island.

For today...one of the aforementioned easterly waves is currently moving across the Kenai Peninsula resulting in scattered showers along the southern end of the Kenai and across the southern end of Cook Inlet into the Barren Islands. Increasing isentropic lift ahead of this wave has also sparked some showers near Talkeetna and the northern Susitna Valley. As the system moves into the valley later today, could see scattered thunderstorms develop and lift north; however, limited instability should hamper overall coverage. Greater thunderstorm chances look to be focused along the foothills of the Alaska Range and portions of the Copper River Basin. Wednesday and Thursday will see thunderstorm chances begin to shift eastwards towards the Copper River Basin, but can`t rule out some storms forming near the Talkeetna Mountains.

Surface high pressure over the Gulf will allow for increasing onshore flow with fog and stratus lingering over the northern Gulf and near coastal areas.

.SHORT TERM FORECAST SOUTHWEST ALASKA, THE BERING SEA/ALEUTIANS (Days 1 through 3: Today through Thursday night)...

The forecast remains on track for more stable air to begin moving into the southwestern mainland over the next few days. With that, thunderstorm activity should be confined to the inland locations near the Western Alaska Range and the Middle Kuskokwim Valley over the next couple days with little western progression from there.
Aside from some morning showery activity most of Bristol Bay and the Kuskokwim Delta should have a pleasant and quiet day today.

The pattern then changes Wednesday and into Thursday. A strong Fall season-like low near the western and central Aleutians will continue to slowly lift northeastward into the Bering over the next few days. The initial front, currently over the eastern Aleutians will continue moving eastward to the southwest mainland by Wednesday. Expect widespread gale-force southerly to southwesterly winds to accompany this front. Strongest wind gusts, up to storm-force will occur through the bays and passes of the Alaska Peninsula (AKPEN) late Tuesday night into Wednesday morning. More importantly, this front will weaken as it moves to the southwest coast with some gales early Wednesday, transitioning to small-craft winds with gale- force gusts by Wednesday afternoon and evening. The precipitation with this front will not make it very far inland of the Bristol Bay and Kuskokwim Delta coasts; therefore, the Lower/Middle Kuskokwim Valley will remain mostly dry with the bear share of precipitation remaining confined to the southwest coast and AKPEN. The Bering low, now occluded, looks to sit and spin in the central Bering for most of Thursday and continue to send waves of moisture to the southwest coast.

.LONG TERM FORECAST (Days 4 through 7)...

A ridge of high pressure in the Interior will continue to dominate through weekend resulting in an isolated rain shower or thunderstorm. High pressure in the Gulf of Alaska will keep the Southcentral dry into the beginning of next week. A series of lows progress through the Bering Sea into the Interior Southwest bringing cooler temperatures, clouds and frequent rain showers to the area through the weekend.

AVIATION

PANC... VFR conditions will persist through the TAF period with southwesterly up-inlet flow continuing into Wednesday. Building high pressure over the area will also result in decreasing precipitation chances near the terminal. Brief southerly gusts are possible from the Turnagain Arm, but are expected to be weaker than yesterday.
