Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 607 AM AKST Tue Feb 20 2024

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

A ~975mb low continues to push northward over the Alaska Peninsula and further inland throughout the day today. A strong south/southeasterly flow and moisture plume continues light to moderate rain across Southcentral, with typical downslope areas remaining mostly dry. A strong pressure gradient between this low and an upper ridge over the eastern Gulf continues strong gap winds through the Turnagain and Knik Arms and south Copper River Valley. While the main Turnagain Arm wind core will remain south of Anchorage, occasional gusty winds are still expected throughout the day, especially across south and west Anchorage.

As the low continues to decay over southwest Alaska through this evening, the main shortwave axis and its front finally push through early tonight, allowing the strong gap winds to come to an end. Cold air advection and up inlet flow may allow precipitation to fill in briefly and end as a mix or snow across the Western Kenai Peninsula, Anchorage Bowl and Mat Valley. Precipitation will continue to linger near the Prince William Sound with Valdez also experiencing a transition to snow. Light to moderate accumulations are likely there starting tonight and will also continue in Thompson Pass ahead of the next system.

As we approach the latter half of Wednesday into Thursday, a large and robust upper low over the Bering Sea will push another system into Southcentral, bringing a period of widespread precipitation. This system will be notably colder, so the threat of moderate to heavy snow returns across portions of Southcentral.
Light accumulations are expected in the Anchorage Bowl, with slightly higher amounts up on the Hillside. The highest amounts will be in and near the Chugach Range, with 1 to 2 feet of heavy wet snow possible in Valdez and up to 3 to 4 feet in Thompson Pass late Wednesday into Thursday.

.SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3)...

Key Messages:

Snow for Southwest * Winter Weather Advisory remains on track for snow and blowing snow in Bristol Bay through 11 AM and for snow in the Lower Kuskokwim Valley through 4PM AKST.

High Winds for the Aleutians * The High Wind Watch was upgraded to a High Wind Warning for the Western Aleutians, including Attu, Shemya, and Amchitka, from 10 PM AKST (9PM HST) tonight through Wednesday 9PM AKST (8PM HST).
Southwest winds gusting up to 85 mph is expected. Snowfall could reduce visibility at times too.

* The High Wind Watch remains in effect for the Central Aleutians, including Amchitka, Adak, and Atka, from Wednesday afternoon through Thursday. Southwest wind gusts up to 70 mph is likely with 80 mph remaining possible.

Discussion:

Accumulations up to six inches of snow is expected for the lower Kuskokwim Valley through this afternoon. Snow will begin to taper off later this morning for the Bristol Bay area and then this afternoon for the lower Kuskokwim Valley. Reduced visibility to half mile at times with blowing snow was reported for Koliganek and New Stuyahok this morning, where northerly winds allowed the air to remain cold enough for snow. East of Koliganek, warmer air and rainfall was reported for easterly winds through the Kamishak Gap, including King Salmon and Iliamna. As easterly winds turn northerly and westerly, temperatures will cool and switch any liquid precipitation back to snow.

A strengthening low is approaching the Western Aleutians. Models have slowed the progression of this low, but strong winds are still expected. Cold air advection behind the cold front is expected to aid in increasing winds throughout the day today.
Snow showers could reduce visibility significantly at times before the peak winds arrive after midnight into Wednesday morning.
Southwest wind gusts up to 85 mph is expected. The High Wind Watch for this area was upgraded to a Warning. The Watch remains out for the central Aleutians as confidence remains lower for the Adak and Atka area. The core of strongest winds is expected to move east and widespread areas of 70 mph gusts is likely, but the location and timing for when those winds decrease is playing a factor in where the strongest winds relative the Aleutians will be located.

The leading occlusion and warm front extending from the low is progressing east today with wind gusts to 45 mph. The Pribilofs could have a period of mix precipitation around midnight. St Paul will more likely remain snow. This front will reach the Southwestern Alaska coast for Wednesday morning and could bring another round of snow for Southwest. The heaviest snow is pointed toward Dillingham, Aleknagik, west to Togiak, the windward side of the Kuskokwim mountains, and along the Kuskokwim coast. As cold air advects across the Bering Sea behind the frontal passages, convective snow showers is expected through the better part of this active week.

.LONG TERM FORECAST (Days 4 through 7: Friday through Monday)...

The upper level low in the Bering weakens and begins an easterly track through Interior southcentral Alaska. It forms a weak center over the Gulf Sunday morning, and dissipates by Monday morning. The tightest gradients remain along the Southern periphery propelled by a generally zonal jetstream. Transient fronts and troughs will bring locally heavy precipitation across the Aleutians, AKPEN and Southwest Alaska. Precipitation will be mostly rain on the Pacific side, with mixed rain and snow or all snow on the Bering side through Friday. Temperatures cool back below freezing over the weekend, expanding the areas of snow through Monday. After a shortwave ridge transits the Bering, another upper level low moves out of the Russian Far East.



AVIATION

PANC...Gusty southeasterly Turnagain Arm winds are expected to persist across the terminal throughout the day today. Ceilings will lower to around 4,000 ft through this evening, but should remain VFR. The strong southeasterly winds will shut off as a front moves through around midnight but it may bring a period of rain and snow for a few hours, potentially reducing visibility to MVFR.
