Area forecast discussion, Dec 24, 4:45 AM AKST, 10 hours 28 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 445 AM AKST Sat Dec 24 2022 .ANALYSIS AND UPPER LEVELS... At upper levels, a large blocking ridge centered over the Chukchi Sea extends south over the Bering Sea and Aleutian Islands. An Arctic trough is elongated over most of southern Alaska and continues to spread a very cold airmass across the Mainland and eastern Bering and Aleutians. At the surface, a front extends across the southern Bering and is decaying as it tracks towards the North Pacific. Rainfall accompanies the front across the eastern Aleutians. An inverted trough is spreading mixed precipitation across the Alaska Peninsula and snow across the southern Bristol Bay area. The rest of Southwest and Southcentral remain dry and cold this morning. Gusty northeasterly surface winds persist across portions of Southcentral but will gradually diminish through today as the Arctic trough tracks towards the eastern Bering. Blowing snow may continue to reduce visibility through Thompson Pass and across portions of the Matanuska Valley this morning. Strong offshore winds continue along the Kuskokwim Delta and Bristol Bay coasts. Wind Chill Advisories remain in effect through this morning for Thompson Pass, the Copper River Basin, and the Middle Kuskokwim Valley. && .MODEL DISCUSSION... Models are still struggling with the evolution of a surface trough near Kodiak Island and the Alaska Peninsula. There is low confidence in the precipitation forecast for Kodiak Island and across southwest Alaska in the short term. Models are also struggling with the evolution of a surface low that is currently centered over the eastern Gulf and is extending its front along the east Gulf coast. There is general consensus that the low will bring light snow to the Cordova/Valdez area this afternoon and evening and then to the eastern Kenai Mountains during the day on Sunday. There is still some disagreement on whether or not the rest of Prince William Sound will see much, if any, precipitation with this system. && .AVIATION... PANC...VFR conditions will persist through this TAF period. Gusty northerly winds are expected to gradually decrease through this afternoon. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3/Saturday through Monday night)... Gusty winds will linger across the Matanuska Valley today due to the tight pressure gradient between the arctic high to east and a surface low spinning up near Kodiak Island. These winds, however, are on the decline from yesterday's peak as the upper-level trough moves to the southwest, away from the region, and the cold air advection wanes. Winds will also continue across bays and passes across Prince William Sound, as well as around Valdez and Thompson Pass, as a second surface low lifts northwest from the eastern Gulf. This feature will also begin to spread light snow across the eastern half of Prince William Sound and the Copper River Basin later today. There is still some uncertainty as to the western extent of the snow; however, the latest guidance all have this swath of snow moving over the eastern Kenai Peninsula by Sunday morning as the low weakens and an easterly flow aloft sets up ahead of the next frontal system. The first low near Kodiak Island, will bring snow and occasional wind gusts across the island today. Snow will likely move in from the east later this morning, lingering through late Saturday evening. Expect mesoscale bands of snow with this feature, which will make it difficult to nail down snowfall accumulation for any given location. However, there could be several inches of snow accumulation for locations under the heaviest and most persist bands. Moving into Christmas and beyond, attention shifts to a large deep low tracking into the Gulf from the Northeast Pacific. A strong occluded front out ahead of the low will reach the Gulf coast/Kodiak by late Sunday, bringing widespread gale to storm force winds across the Gulf coastal waters along with moderate to heavy precipitation along much of the coastal zone. Prevailing low level easterly flow will lead to upslope flow and enhanced precipitation amounts across the eastern Kenai Peninsula Mountains. Much warmer air will also accompany the front leading to a fairly quick transition from snow to rain for areas along the coast near sea level. Snow levels for coastal mountains will quickly rise Sunday afternoon/evening, reaching 1000 feet or higher. Precipitation will linger along the coast all the way through Monday. While some moisture will attempt to cross over the coastal mountains, dry and cold air inland will make it difficult to saturate the low levels of the atmosphere. As a result, inland areas of Southcentral look to remain dry. Temperatures will also moderate by Monday with winds increasing once again through the Matanuska Valley and down Cook Inlet in response to the low moving into the western Gulf just east of Kodiak City. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3: Today through Tuesday)... Colder temperatures and northerly offshore flow continues across the region as a strong shortwave originating from an upper-level trough located across Yukon, Canada continues to advance westward towards Bristol Bay. As a result, wind chills across the region will be in the negative double digits for the next several days. A Wind Chill Advisory is still in effect for the lower Kuskokwim Valley until this afternoon. A surface low will track across the Alaska Peninsula today, but models are having a hard time handling the exact track of the low, and will therefore, impact where the highest winds, precipitation, and blowing snow concerns will be. This forecast package reflects snow continuing for the Alaska Peninsula today before slowly making its way northward towards the Bristol Bay region for tonight, and then reaching the Kuskokwim Delta coast for late tonight into Sunday. As the aforementioned low tracks northeastward along the Chain, northerly winds will increase region wide. With this, the potential for blowing snow coincided with reduced visibilities becomes possible along the Bristol Bay coast and portions of the Alaska Peninsula. As a result, a Winter Weather Advisory has been issued for the Bristol Bay coast. Total snow accumulations of 6 to 10 inches along the southern Bristol Bay coast and 4 to 6 inches along the northern Bristol Bay coast are expected. Expect visibilities reduced to as low as 1/2 mile from Dillingham north and west and from Port Heiden to King Salmon possible as well. A strong North Pacific low and its associated front will approach and impact the region Sunday through Tuesday. This will bring a rain/snow mix to the Alaska Peninsula, while mostly snow is expected for the western interior portions of Bristol Bay. Higher accumulations are forecasted to stay confined to the mountain areas at this time. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3: Today through Tuesday)... Active weather will continue for the Bering and Aleutians for the next several days. A surface low tracking across the Alaska Peninsula will today will eventually make its way into the eastern Bering. Models are having a hard time handling the exact track of the aforementioned low, but colder air and strong winds are likely to occur with snow being the main precipitation type for this system. Depending on where the low tracks and how strong the winds get, the potential for blowing snow coinciding with reducing visibilities is possible for some locations. Snow will make its way to the Pribilofs late tonight into Sunday morning. Strong winds should move out of the area before the snow hits, but some blowing snow may still occur.The system then continues westward through the Bering through Sunday afternoon into the evening before making a southern turn to the North Pacific while crossing the central Chain through Monday. Snow amounts appear to be light for the Aleutians overall, with the highest accumulations confined to the mountain areas. Be sure to check back in with the forecast for updates as the evolution of this system becomes more clear. .LONG TERM FORECAST (Days 4 through 7: Tuesday through Friday)... The latest operational model runs and ensemble means seem to be in a decent agreement with an upper level low over the western Bering Sea near Adak, and high pressure remaining over Siberia. While the upper low sits nearly stationary between Tuesday and Wednesday, a series of North Pacific systems rotates around the low, moving north-northeastward past the Aleutians and into the Gulf of Alaska. This will bring an unsettled pattern for all of the coastal areas of Southcentral heading into late next week. While specific details still need to ironed out, persistent onshore flow will favor moderate to heavy precipitation for the coast, with much of the mainland remaining relatively dry during the period. A general troughing pattern out west will result in a wet pattern for much of the Bering Sea and Aleutians. Cold, northerly flow over the relatively warm waters will also help generate widespread showers over the Pribilof Islands and along the Aleutian Chain. && .AFC WATCHES/WARNINGS/ADVISORIES...
