Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 549 PM AKDT Tue Jul 8 2025

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: This afternoon through Friday evening)...

The upper low in the Gulf of Alaska earlier has since shifted to Southeast Alaska today with transient high pressure ridging now overhead. Drier conditions are expected for most areas today.
Rain showers are likely along northern portions of the Susitna Valley and Copper River Basin, and isolated thunderstorms are possible this afternoon along the western Alaska Range, Talkeetna Mountains, and eastern portions of the Wrangell Mountains. A slight chance of an isolated thunderstorm also exists for locations along the western facing slopes of the Kenai Mountains this afternoon and early evening. Expect showers to persist for the aforementioned inland areas through Wednesday while tapering off overnight tonight for the Western Kenai Mountains. While thunderstorm chances will diminish for most areas, there continues to be some isolated potential over the Talkeetna Mountains and extreme western Copper River Basin Wednesday afternoon.

Stratiform rain will move back in along the coast late Tuesday night/early Wednesday morning ahead of a front set to move into the southwestern Gulf on Wednesday. Additionally, southeasterly gap winds will increase Wednesday through Turnagain, the Knik River, and the Copper River Valley. Expect mostly dry conditions through Anchorage, Palmer, and the southern Copper River Basin with the southeast surface flow. Southeast winds peak Wednesday evening before slowly diminishing overnight Wednesday into Thursday morning.

The next front moving in on Wednesday will impact Kodiak Island first, bringing rounds of rain and gusty easterly winds Wednesday into Thursday before pushing northwards towards the north Gulf coast. Gale force winds are expected to move north with the front, pushing gusts to storm force through the Barren Islands and the setting up a barrier jet along the north Gulf coast Thursday afternoon. The barrier jet is expected to be high end gale force winds with a corridor of storm force gusts. The best chance for storm-force gusts is along the northern Gulf Thursday afternoon into the evening hours. The wettest locations associated with this storm will undoubtedly be along the Southcentral Coast and Kodiak Island, with inland locations seeing periods of lighter rain showers mostly confined to the terrain.

The main upper low energy will shift to Southeast Alaska for Friday with higher pressure trying to nudge in over Southcentral.
This will open the door to more easterly waves moving into the Copper River Basin and perhaps the Susitna Valley for Friday when more widespread shower potential, and potentially thunderstorm development, returns to the forecast for the Southcentral interior.


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

Weak ridging in the Southwest Interior will continue to slowly erode as a weak front moves southeastward this afternoon. A slow moving low in the Central Aleutians will continue to bring rain and gusty winds across the Aleutians and Alaska Peninsula through tomorrow before entering the Gulf of Alaska.

Instability from the front moving southeastward and limited breaks in the clouds resulted in late morning thunderstorms today just north of Sleetmute. As this front continues its trek today, an area of rain showers and a 20% chance an isolated wet thunderstorm in the Crooked Creek to Lime Village area through this evening is possible into mid-eveningtoday. Tomorrow, the chances of afternoon thunderstorms in the Kuskokwim Valley from Lime Village to Crooked Creek northward decreases to 10% to 20%.
Temperatures slightly increase in the Interior areas of the SW Mainland though decrease slightly along the coastline.

Elsewhere, a slow moving low in the Central Aleutians continues to bring southeasterly winds to the Eastern Aleutians and eventually to the Pacific side of the Alaska Peninsula tomorrow afternoon and evening. Rainfall will accompany these stronger winds through tomorrow evening too; heaviest on the Pacific side.
The greatest chances for rain showers in the Alaska Peninsula and areas along the Bristol Bay coastline is Thursday. In its wake, northerly winds and drier conditions will prevail. Areas of fog are expected in the Pribilof Islands, coastal SW Alaska and portions of the Central Aleutians to the Alaska Peninsula tomorrow and Wednesday morning.

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

The long term begins with a broad longwave trough over the Bering and Gulf with 3 to 4 shortwaves embedded within it. Over the Mainland, a strong ridge extends from the Chukchi Sea southeast into Southcentral. Through Tuesday the trough will shift east over the western half of the state and the Alaska Peninsula while a stout ridge develops over the AlCan, Yukon Territory and BC. The transition of the pattern from Saturday to Tuesday is messy, particularly with how the troughs will interact with the Interior ridging. Over the weekend we're looking at a showery pattern over Southwest and over the mountains of Southcentral. Moving into the start of the work week next week models indicate a potentially wet system developing in the north Pacific and moving into the Southern Mainland. With the amplification of the pattern, there will be a tropical tap to the moisture moving north, so some areas will receive some moderate rain. Right now there is a large meridional spread in the storm track with varied impacts throughout the region. Additionally, there is a signal for a broad southwesterly flow to set up in the Bering, which may bring concerns to the Southwest coast. We will continue to monitor this.

AVIATION

PANC...VFR conditions will persist. The southeasterly Turnagain Arm winds are expected to develop this evening, but a bit later than the typical onset. However, these winds are then expected to increase overnight with gusts up to 30 kt possible after midnight and through the day Wednesday.
