Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 400 PM AKST Tue Feb 18 2025
.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)...
Most of the active weather this week will be focused along the coast, where easterly flow will lead to persistent precipitation through Thursday. An occluded front over the north Gulf coast this afternoon will continue to weaken through tonight. This will allow precipitation to lighten up tonight off before rejuvenating again on Wednesday as another surface low moves towards the coast. The low dissipates as it moves onshore Wednesday night and is quickly followed by a third front extending off a North Pacific low approaching the Alaska Peninsula on Thursday. This more compact surface trough passes over Southcentral Wednesday night through early Thursday and has the potential to carry over more widespread but light precipitation, especially for locations along the Copper River Basin.

An occluded front over the north Gulf coast this afternoon will continue to weaken through tonight. This will allow precipitation to lighten up tonight off before rejuvenating again on Wednesday as another surface low moves towards the coast.

This more compact surface trough passes over Southcentral Wednesday night through early Thursday and has the potential to carry over more widespread but light precipitation, especially for locations along the Copper River Basin.
.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3: Tonight through Friday)...
A low pressure system centered south of the Alaska Peninsula extends its occluded front across the eastern Aleutians, Pribilof Islands, and into the Kuskokwim Delta this evening, leading to light snow mixed with freezing drizzle, where only low-level moisture and a stratus deck is present. As the low tracks into the eastern Bering Sea tonight, its front brings gusty winds to the Pribilof Islands and the Kuskokwim Delta coast. Combined with light snow, visibilities may drop to one mile or less at times.
The front exits west into the Bering Sea by midnight, ending the threat of blowing snow. As the low tracks toward the Pribilof Islands on Wednesday, another round of snow arrives and transitions to a rain/snow mix by Wednesday evening.
Another North Pacific low tracks south of the Alaska Peninsula by Thursday morning, continuing a pattern of showery weather and warm, southeasterly flow into Southwest Alaska. Models begin to diverge late on Thursday with the track of the low (whether or not it crosses into Bristol Bay) and the potential for precipitation along the northern Bristol Bay coast. However, there is more support for the low remaining south of the Alaska Peninsula and generally suggest that if it precipitates in the greater Bristol Bay area, it is more likely to be snow than rain. Out west, the low tracking across the Pribilofs ends up in the western Bering Sea Thursday and Friday, bringing scattered snow showers to the western and central Aleutians through the end of the week.
.LONG TERM FORECAST (Days 4 through 7) Saturday through Tuesday...
Little change from previous discussions... The persistent broad upper level troughing over the Bering Sea and Aleutians, combined with the strong upper level ridging over much of the Alaskan Mainland and along the Panhandle, will continue to dominate the weather pattern through the forecast period. Equal weight was given between all of the global models which have come into relative agreement with the larger features. However, there is some uncertainty about timing and intensity of the upper level shortwaves and associated weak surface lows.
This pattern will allow for small, fast moving shortwave troughs and associated surface fronts to quickly move across the Aleutian Islands and coastal South Central regions. This stubborn weather pattern will bring a more southerly wind pattern and unseasonably warmer temperatures across much of the region with higher precipitation amounts falling mainly as rain along the northern Gulf coastline and through the Central Aleutians. There is a potential for heavy snow accumulations in the higher coastal elevations with each successive system.
