Area forecast discussion, Dec 4, 6:02 PM AKST, 10 hours 2 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 602 PM AKST Sat Dec 4 2021 .ANALYSIS AND UPPER LEVELS... A weak meso-low in the northwestern Gulf continues to produce convective snow showers for the marine areas surrounding Middleton Island. Fog and low stratus from earlier this morning persisted into the early afternoon for parts of Kenai Peninsula stretching northeastward to Palmer. A sharp upper level trough continues to move over the western part of the state, including the eastern Aleutians, toward Southcentral. Some weak overrunning ahead of the trough continues to produce short periods of light snow along the Alaska Peninsula through parts of inland Bristol Bay. Precipitation associated with this trough has begun to taper, however, as the trough tracks farther inland and weakens. Out west, a deep low near Russia is tracking eastward toward the western Bering. Its front pushes through the Bering Sea today, spreading southerly gale-force winds across the Bering and Aleutian Chain. A nearly 200kt upper level jet streak is moving eastward along the southern Bering/Aleutian Chain and pushes this system into southern Alaska through today. There is deep subtropical moisture associated with this system visible on satellite. && .MODEL DISCUSSION... Model solutions remain in good agreement taking the upper level trough eastward across the state, with it weakening as it moves. In addition, all models agree that the meso-low currently in the northwestern Gulf will remain nearly stationary throughout the forecast period. Models are relatively consistent with the overall track of the system moving across the Bering. However, there is some disagreement with the track of a surface low that develops along the system's front Sunday. For Monday, the GFS is initially tracking the surface low farther north over the Alaska Peninsula, while the other models bring the low south of the Alaska Peninsula and closer to Kodiak Island. Depending on where the low tracks will determine whether certain locations will see southerly vs southeasterly flow, where warm air advection will occur, which precipitation type will occur and where, and how much snow accumulation there will be for a given location. For now, this forecast leans more towards the NAM and the GEM as the GFS is an outlier with how it handles the next low. && .AVIATION... PANC...Low stratus, courtesy of the Knik Arm, is keeping conditions IFR. There is low confidence in exact timing of how long these conditions will persist, but expect a transition to VFR later this evening. Mostly VFR conditions are then expected to continue through early Sunday morning, thereafter predominantly MVFR conditions are expected due to light snow reducing visibility. Winds are also expected to shift to southeasterly around this time, but not be overly strong. &&.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: Tonight through Tuesday)... Light snow showers are developing near Prince William Sound in response to an upper level wave and associated mesolow currently situated south of Seward. Meanwhile, a shortwave trough is crossing the western Alaska Range this evening. This will bring a chance of light snow into Anchorage Bowl northward into the Susitna Valley for tonight through Sunday morning, though not much snow accumulation is expected. A major pattern shift will be getting underway as a broad longwave trough over the Bering Sea will shift over the eastern half of the interior state. Beginning Sunday afternoon, a strong frontal boundary ahead of the trough will provide widespread snowfall and gusty winds in the Cook Inlet region. As the front progresses eastward, snow and winds will spread north and east across Southcentral. With upper level dynamic support and a deep moisture fetch out in the Pacific, this will be a long duration snow event expected for all areas, especially along the coastal mountain ranges. Additionally, strengthening low level south to southeasterly winds ahead of the front will lead to areas to blowing snow and reduced visibility at times. Please see our webpage that has several products out including Winter Storm Warnings for the Susitna Valley and Prince William Sound. Thereafter, a deep surface low will form south of the Aleutians on Monday morning. Model guidance vary on the track of the low, but the general trend is to have it migrate along the AKPEN and into the western Gulf sometime Monday night into Tuesday morning. Depending on future model runs and consistency, expect a continuation of snow and winds to persist through much of next week. Stay tuned for the latest updates. &&.SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 to 2: Today through Monday)... It is now the eve of the well-advertised and likely quite impactful winter storm system, with weather headlines in effect for all zones covering the Southwest forecast area. Winter Storm Warnings remain in effect for the Kuskokwim Delta, Middle Kuskokwim Valley, and Bristol Bay, with impacts expected to begin late tonight into the very early morning hours of Sunday. A storm force front will move onshore overnight tonight, bringing intense snowfall and fierce winds gusting as high as 65 mph for much of the Y-K Delta and inland areas of the Kuskokwim Valley. Winds will be slightly lower over Bristol Bay, with gusts to 50 mph remaining possible. The unusual combination of strong southerly winds with surface temperatures initially cold enough to support heavy precipitation in the form of snow could lead to near whiteout conditions coupled with the strongest winds, especially during the day on Sunday. There continues to be potential for snow to mix with or even changeover to rain with strong warm advection and mixing down of warm air from aloft, mainly close to the coast over Bristol Bay and the Y-K Delta. This combined with a somewhat faster progression for the front should result in somewhat lower snowfall totals then earlier anticipated. Still, snowfall rates remain on track to be very intense until temperatures warm to or slightly above freezing for areas where mixing becomes an issue. The other primary impact from this system will be limited to immediate coastal areas. The strong onshore winds up to storm force will potentially enough to cause major disruptions to the existing sea ice pack, with water likely to well up through cracks in the ice and possibly pool over shorefast ice close to the coastline. There remains a high amount of uncertainty as to just exactly how the ice in place will respond to these winds, but there is enough confidence for potential impacts to issue a Coastal Flood Warning for the Kuskokwim Delta Coast and a Coastal Flood Advisory for the Bristol Bay Coast with this package. Again, uncertainty for the outlined impacts in these products remains somewhat higher than anticipated impacts from inclement winter weather. Interested parties in and around coastal communities should take appropriate precautions and stay away from the ice at least until the winds subside early on Monday morning. Looking further into Monday, another change in the forecast is that a triple-point low is now expected to form along the front near the Aleutians and Alaska Peninsula, then track northeast towards the Cook Inlet and perhaps even as far north as Bristol Bay by Monday afternoon. This could bring renewed light to moderate snowfall back across much of the area, with several more inches of snow possible for parts of the Middle Kuskokwim Valley and Bristol Bay interior depending on the low track. Check back for forecast updates on this potential for additional snowfall on Monday as the details for the track and timing of the second system become better refined. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS/AKPEN (Days 1 to 2: Tonight through Monday)... An intense, storm force front is well on its way across the Bering this evening, with moderate rain and wind gusts as high as 55 kt already observed for parts of the western Aleutians earlier in the day. These strong and gusty winds are on track to impact the Pribilof Islands during the next several hours, with gusts up to 60 mph possible and moderate to heavy rainfall rates likely. The front will move at quite a fast clip across the Bering, reaching the Alaska Peninsula and Southwest coastal areas by late tomorrow morning. Meanwhile, the parent low will send a surge of cold air back across the northern Bering behind the front, with storm force winds and gusts near Hurricane force possible across mainly the western Bering through tomorrow morning. Westerly winds will weaken throughout the day on Sunday as snow showers spread back across the Bering with the colder airmass, with periods of snow passing over the Pribilof Islands at times through Monday. Additionally, another low is expected to form somewhere along the front as it stalls out along or just south of the Aleutians. This could bring renewed periods of rain/snow to the eastern Aleutians and southern Alaska Peninsula on Monday as the low moves northeast towards the Cook Inlet region. && .MARINE (Days 3 through 5: Tuesday through Thursday)... Gulf of Alaska: Southerly flow over the gulf will transition to a westerly direction on Tuesday as an aggressive shortwave trough digs eastward toward the Panhandle. Small craft to gale force winds are forecast to expand in coverage across much of the gulf and linger through Thursday as a series of smaller disturbances pass through the region. Westerly storm force gusts may become an increasing concern across the Kamishak Bay Gap, the Barren Islands and east, and points east of southern Kodiak Island over the latter half of the day on Tuesday. Later next week a large and potentially significant area of low pressure will move into the southern Bering with enhanced south to southwest gulf winds returning to the gulf late Thursday into Friday. Bering Sea: A break from enhanced weather early next week will likely be short-lived across the Bering. Guidance is suggesting that a shortwave trough will dig across the Bering and into the Kuskokwim Delta Tuesday into Wednesday. Gale west to northwest winds will spread over much of the Bering, clipping the Western Aleutians and expanding southeastward through the Alaska Peninsula. Gusts through gaps in the Alaska Peninsula should be near or above storm force. These conditions will be followed by the arrival of yet a larger and stronger upper low into the Bering Wednesday into Thursday. Guidance hints at an area of low pressure lifting across the Western Aleutians late Wednesday and undergoing significant amplification over the southern Bering on Thursday. While still a ways off, this second low would promote another round of widespread gale to storm force winds over the Bering and the Aleutian Chain on Thursday and Friday of next week. && .LONG TERM FORECAST (Days 4 through 7/Wednesday through Saturday)... Weather is expected to remain very active in the long term with the jet remaining between 50 and 60 north. This will keep things very progressive with the storm track from the Bering Sea into Southcentral. To start things off on Wednesday another surge of warm air and moisture is expected to move northeast from the coast of Japan, rapidly tapping into cold air from Siberia to generate yet another deep low in the Bering. Bombogenesis appears likely once again with storm to hurricane force winds over the marine areas of the Bering Sea. There is some uncertainty on the exact track as the system moves east on Thursday, making landfall somewhere in Southwest Alaska and then forming a triple point low in the Gulf on Friday night. Rain or freezing rain will be possible on Thursday for the Southwest coast, with heavy snow likely in the interior. As the front moves across the Alaska Peninsula another large push of moisture is expected to impact Southcentral. Some coastal areas along the Gulf may see a period of rain Thursday afternoon but overall the cold air is expected to wrap around the low rapidly, switching everything back to snow by Friday afternoon. With the overall progressive nature of this pattern, the storm will move out into Southeast Alaska on Saturday. Uncertainty remains fairly high, so stay tuned. && .AFC WATCHES/WARNINGS/ADVISORIES...
