Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 345 PM AKDT Sat Apr 13 2024

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

The forecast remains on track, with only minor adjustments to winds and this afternoon/evening's showers. The outlook is for clearer skies and dry weather through Monday evening, after which a plume of tropical moisture will approach the Western Gulf. No major hazards are expected at this time.

Diving into the details...a vertically stacked low is currently located off the coast of Eastern Kenai Peninsula. Weak shortwaves moving around the low, in conjunction with daytime heating, are producing weak convection across Southcentral. Most areas should stay dry, but scattered showers are possible through tonight in areas of stronger convection.

From tonight through tomorrow morning, the low will exit towards Southeast Alaska and a ridge will build in from the west. As the low exits, any lingering precipitation will taper off, and gusty offshore gap winds will increase. The strongest of these winds are expected through Kamishak Gap, Seward, and Whittier, where winds could gust as high as 45 mph. Winds will diminish through Sunday afternoon as the ridge becomes established over Southcentral Alaska. Aside from localized gap winds, much of the area should see some pretty nice conditions. Temperatures gradually trend upwards as we head through early next week, with daytime highs approaching the mid to high 40s by Tuesday. While this might seem like an occasion to break out the shorts and t-shirts, be sure to keep your jackets around as nighttime lows will still dip into the 20s and teens.

From Monday night through Tuesday, cloud cover will return from south to north as two North Pacific lows merge south of Kodiak Island. Southeasterly flow ahead of these lows will lead to upslope precipitation along the Gulf coast of Kodiak Island, the Alaska Range, Eastern Kenai Peninsula, and Prince William Sound.
For Kodiak Island, expect precipitation to intensify Tuesday afternoon/evening as the low's front begins to push in. There are some model differences in timing, with the potential for the front's arrival to be delayed if the ridge is slower to be displaced.

.SHORT TERM FORECAST SOUTHWEST ALASKA, BERING SEA, AND ALEUTIAN ISLANDS (Days 1 through 3: Tonight through Tuesday)...

Mostly clear weather over Southwest Alaska will give way to overcast skies later this evening as a weak upper shortwave drops into the area from the north and around the building ridge over the eastern Bering Sea. Most snow shower activity associated with this system will stay confined to the western facing slopes of the Kuskokwim, Kilbuck, and Ahklun Mountains tonight. Any snow showers taper off by Sunday morning as the ridge axis moves overhead.

Attention then turns to a powerful North Pacific low that will impact much of Southwest Alaska, the Alaska Peninsula (AKPEN), the Aleutian Chain, and the Pribilof Islands the rest of this weekend. The low looks to lift into the Bering Sea through the day on Sunday. Storm-force winds will be common throughout the central Aleutians most of the day and perhaps making it as far east as the eastern Aleutians late Sunday night into Monday morning. Expect mostly rain or rain/snow mix with this system across the Aleutian Chain. The front makes it to the Pribilof Islands late Sunday night into early Monday morning. Snow and blowing snow look likely for the Pribilofs late Sunday night through Monday morning with the worst conditions early Monday morning. The front then makes it to the coast of Southwest Alaska Monday afternoon. The low, now occluded, will bring in cooler air as south to southeast winds ramp up along the coast Monday. Snow and blowing snow look to be the primary threats along Nunivak Island, the Kuskokwim Delta Coast, as well as for the Western Capes of northwestern Bristol Bay. As this low lifts into the Bering Strait late Monday night, precipitation will begin to taper off. Another North Pacific low looks to impact the eastern Aleutians, AKPEN, and coastal Southwest Tuesday with more gusty winds, rain, and snow.

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

The long term period will begin with a deepening North Pacific low south of the Eastern Aleutians on Wednesday. Strong northerly flow across the Bering, associated with the passage of several shortwave troughs, will promote gusty conditions, scattered snow showers, and below normal temperatures across much of the Bering and the Aleutians. At the same time, a front is forecast to lift into the AKPEN and continue into the Gulf of Alaska and Kenai Peninsula through Wednesday night. Southeast flow associated with the front will bring warmer temperatures and precipitation from the AKPEN and Kodiak Island to the Kenai Peninsula. Above normal chances for a mix of rain and snow are forecast for Southwest Alaska on Wednesday and Thursday. The North Pacific low is then forecast to shift southward and further away from the region by late Thursday, as each trough from the Bering digs the low further and further south. Of note, potential exists for an atmospheric river to be directed into the Kodiak Island region, with heavy rain. Friday and Saturday will see precipitation begin to wane as the low pivots even further away from the region. A weak front moves into the Western Aleutians Friday night and Saturday but dissipates by Saturday night.
