LONG TERM FORECAST (Days 4 to 7)
Ridging across the Eastern Aleutians and Southwest Alaska breaks down later this week as a low and its associated trough moves through the Bering Sea. This Bering low and its associated front brings rain showers and a return to cloudy skies. As the front moves toward the Mainland, persistent northwest flow will overtake the Aleutians bringing continued rain showers, fog and cloudy sky. Models are in better agreement on the general track of a second low crossing the Bering Sea and reaching the Central Aleutians this weekend. In its wake, it will bring a change to northerly winds for the AK Pen, Eastern Aleutians and Southwest Alaska early next week.
A receding ridge of high pressure in the Southern Gulf of Alaska brings the return of southwest to northeast flow into Southcentral for the week's end. This flow results in rainy and cloudy conditions for the Prince William Sound and eastern Kenai Peninsula form late this week into the end of next weekend. Timing and exact location differences are present though a weak low moves through the Northern Gulf of Alaska in the latter part of this weekend bringing rain to already saturated Prince William Sound coastline.
