Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 410 PM AKDT Sun May 19 2024

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

An upper level trough currently located over the Gulf of Alaska near Prince William Sound will begin moving eastward starting tonight before departing into Canada. As the low moves eastward, a few shortwaves will spin around the low back into the northern parts of the Copper River near the Wrangell Mountains. Widespread precipitation is expected across the eastern portion of the forecast area through tomorrow afternoon, with some areas near Paxson and Mentasta Lake receiving snowfall tonight of around 1-2 inches. Warmer surfaces like roads will struggle to accumulate snow, but grassier spots could see snow stick to the surface.

For the rest of Southcentral through Tuesday afternoon, weak ridging will cover the area and allow for a brief period of dryer weather. Areas of partly cloudy skies over the Kenai Peninsula and portions of the Mat-Su will also be possible before the next system impacts the region.

An upper level low in the Bering will continue to move eastward, with its front moving into Southcentral by Tuesday afternoon.
Widespread heavy rain and pockets of snow near the mountainsides will pass over the region through at least Wednesday afternoon.
With the ridge just of to the east, a building pressure gradient over the Chugach and Kenai Mountains will result in stronger southerly gap winds taking place Tuesday afternoon near the Kamishak Gap, Turnagain and Kink Arms, and the Copper River Basin.
Southwesterly flow aloft should allow the Anchorage Bowl to get some rainfall Tuesday afternoon, but a switch in flow to a southeasterly direction on Wednesday will cause downslope drying to occur over the area. This next system will result in a brief cool down over the entire region, but should quickly rebound to closer to normal temperatures later in the week.

.SHORT TERM FORECAST SOUTHWEST ALASKA, THE BERING SEA AND THE ALEUTIANS (Days 1 through 3: This afternoon through Wednesday evening)...

After some fog and low stratus this morning, conditions have improved for Southwestern Alaska as today progressed. There is another chance for low stratus and misty conditions Monday morning, especially for coastal locations of Bristol Bay and the Kuskokwim Delta. Other than the potential for low stratus, the first half of Monday is looking quiet across the southwestern mainland. A Kamchatka low will enter the Bering Sea tonight and send its front across the Aleutian Chain, to the Alaska Peninsula (AKPEN), and eventually to the southwestern coastline by Monday afternoon. There looks to be enough cold air in place for Nunivak Island and northern portions of the Kuskokwim Delta coast to start as a period of snow or rain/snow mix mid-day Monday before changing over to rain in the afternoon and evening. This front, along with its widespread precipitation, will continue to push inland to interior Southwest through Tuesday. Moderate to heavy rain is possible for Bristol Bay Tuesday morning and into the afternoon. In addition to the heavy precipitation, the pressure gradient between this front and higher pressure in the Gulf of Alaska will promote gusty southeasterly Kamishak Gap winds into interior Bristol Bay for Tuesday.

Colder air will work in behind the front Tuesday morning to the Kuskokwim Delta where additional shortwaves rotating around the upper low in the Bering will promote more rain/snow mix there.
This will be same case for the Pribilof Islands as well.
Confidence is low if areas as far west as Bethel will see any rain/snow mix on Tuesday. The low itself moves to the Kuskokwim Delta coast Wednesday morning as widespread showers continue through Wednesday for the southwestern mainland and Bering Sea side of the AKPEN.

The next system, a stronger North Pacific low, looks lift to the western Bering and western Aleutian Chain Wednesday. This gale- force low sends its front eastward to the central Aleutians by Wednesday evening. Moderate to heavy rain will accompany this front.

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

Thursday, an upper-level low centered over the Bering on Thursday begins to elongate southeastward into the Gulf. Surface precipitation may start as snow then transition to rain for the Western Capes, Kuskokwim Delta, and Nunivak Island. A brief ridge forms before the next upper-level low consolidates and moves eastward from Attu Island. By Friday the new low has transited the Bering and continued across Southwest Alaska into the Gulf by Sunday. The highest rain amounts are expected along the Kenai Peninsula and the northern Gulf coast. High pressure builds behind this low across the Bering Saturday and Sunday.

AVIATION

PANC...VFR conditions will persist with scattered showers and ceilings around 4000 ft. Light northerly winds shift to the southeast for the afternoon/evening as a weak Turnagain Arm wind develops. Southeasterly winds will diminish through the evening hours, with ceilings rising above 5000 ft.
