708 FXAK68 PAFC 130253 AFDAFC Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 553 PM AKST Wed Nov 12 2025 .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: Today through Saturday morning)... Dry conditions and below normal temperatures revisit Southcentral this afternoon, however, an inbound shortwave trough from the west brings increasing cloud cover which will inhibit the development of fog and low stratus overnight. Should sky conditions become clear, patchy freezing fog may still be possible. Cloud cover will also keep low temperatures 5 to 8 degrees above Tuesday night`s lows. Thursday will see increased clouds, but otherwise very similar conditions to Wednesday for most of Southcentral. Precipitation should remain limited to Prince William Sound and the north Gulf coast and diminish through the afternoon. Friday afternoon a low in the Bering pushes into the Gulf with widespread small-craft and areas of gale force winds across the entrance to Cook Inlet and through Shelikof Strait. Models are projecting the formation of a triple point low along the trough near Kodiak Island. Consensus varies on timing and position of where that takes place, from just north to just south of the island. Wind fields may change rapidly, but the general consensus of rain and higher elevation snow for Kodiak and then coastal Kenai Peninsula is likely to remain unchanged for Friday. By saturday morning the low will have moved south of the Kenai Peninsula, with little to no precipitation reaching the western Kenai and Anchorage. && .SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3)... Light snow continues this afternoon for the northern Alaska Peninsula, Bristol Bay, and Kuskokwim Delta along the decaying frontal boundary which stalled along the coast today as it reached the Mainland. Any remaining snow showers are expected to continue to diminish through this evening with additional accumulation up to one inch. Elsewhere, relatively quiet weather persists this evening as the Bering experiences a lull between weather systems. By Thursday morning, a gale-force low lifts towards the Eastern Aleutians and Alaska Peninsula. As the system reaches the southern Bering, a negatively tilting upper level trough pushing east across the Bering helps to strengthen this system as it takes on a more complex structure. Models have come into better agreement on the track of the low through Thursday afternoon, but the biggest forecast challenge continues to be how far north the low progresses in the southern Bering and the timing of the strongest winds affecting the Aleutian Chain. By Thursday afternoon, winds ranging from small-craft to gale strength are expected to pick up across much of the Aleutian Chain and Alaska Peninsula. Winds are expected to peak Friday morning through Friday evening as the low begins to pivots east towards the Gulf. Widespread westerly gales are expected across the Central and Eastern Aleutians Friday, with westerly storm force gusts possible roughly from Atka to Unalaska through Friday afternoon. Heading into the weekend, the next low and potentially gale force front tracks across the western Aleutians and Bering Sea through Saturday morning. Shortly after, this system begins to interact and phase with a much stronger North Pacific low as it lifts across the Aleutians and into the Southern Bering Saturday into Sunday with the potential for the storm to deepen to a sub-950 mb low. There are a lot of details to iron out with this system and any impacts related to the storm will be highly dependent on storm track, in which confidence remains low at this time. Please stay tuned and monitor the forecast for this upcoming system. -JH/AM && .LONG TERM FORECAST (Days 4 through 7: Sunday through Wednesday)... For Southcentral, the long term forecast reflects the eastward displacement of the persistent Gulf of Alaska trough into Canada by early monday morning, allowing a ridge of high pressure to ridge into the region. This will bring cooing temperatures across Southcentral through mid-week. The larger weather concerns are for Pribilofs, Southwest Alaska and Aleutian Islands. A deepening North Pacific low, embedded with a broad upper level Bering trough will lift northwestward from the Central Aleutians, delivering gale-to-storm force winds and heavy precipitation across the southern Bering Sea, including the Pribilofs before before weakening early in the week. A second North Pacific low pressure system is forecasted to cross over the Aleutians late Monday and into Tuesday. This will bring sustained southerly to southwesterly flow and elevating precipitation probabilities across Southwest Alaska. The exact path of the system is somewhat uncertain as there is very little agreement between the major global models. A frontal boundary advancing onshore Tuesday and into Wednesday will reinforce above-normal temperatures and precipitation with the potential for coastal rainfall and inland mixed precipitation in the elevated terrain. && .AVIATION... PANC...Areas of fog and low stratus have persisted across the northern Cook Inlet just off to the northwest of Anchorage overnight. There will continue to be a threat for intermittent periods of IFR conditions or lower if any of stratus/fog manages to drift southeast into the terminal, especially this morning. Otherwise, VFR conditions and light winds will persist. -AS && $$
