Area forecast discussion, Dec 23, 5:15 AM AKST, 10 hours 38 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 515 AM AKST Wed Dec 23 2020 .ANALYSIS AND UPPER LEVELS... The upper-levels are dominated by a broad long-wave trough extended from Siberia over almost the entirety of the Bering to the western half of the state. Downstream, a ridge continues to extend from the Canadian Rockies to the Brooks Range. This set up is allowing shortwaves to eject from the long-wave trough and move from the North Pacific into the Gulf of Alaska under the influence of a deep southwesterly flow. The first of these waves is moving onshore along the Southcentral coast early this morning. At the surface, this feature is supporting a a 980mb low over western Prince William Sound with a trough moving up Cook Inlet into the southern half of the Susitna Valley. Colder air is working in behind these features, allowing a wintry mix of precipitation to change back to snow as the surface low lifts north. Light snow is falling from Eagle River north across the Mat-Su valleys this morning, but is already ending from Kenai north to Anchorage. Elsewhere, the gusty winds along the immediate coast are winding down as the surface front lifts onshore. Out west, a second shortwave is moving toward the coast of Southwest Alaska. This feature is producing snow showers from Bethel to interior Bristol Bay as temperatures this morning range from 25F to 30F. Elsewhere, a vertically stacked 962 mb low just south of Saint George is beginning to trek to the northeast. As it does, scattered rain/snow showers continue from the Pribilofs down to the central and eastern Aleutians. A secondary trough dropping south along the back side of the low is producing gales, as seen in the latest ASCAT pass, over the western Bering. Farther west, a front attached to a 976 mb Kamchatka low is approaching the Attu and Shemya. && .MODEL DISCUSSION... The biggest forecast challenge in the short term looks to be the strength and position of the next North Pacific low as it lifts northwest of Kodiak Island and potentially across the AKPEN by Friday morning. The 00z GFS was the fastest and strongest, bringing a more compact 980 mb low over Bristol Bay Friday morning. The 00z NAM, GEM, EC all had a weaker solution that either elongated the low at it interacts with the mountains along the AKPEN, or kept the main circulation south of the AKPEN and lifted an inverted trough over Bristol Bay. The 12z NAM is sticking to its guns with the 06Z GFS moving more toward a NAM solution, albeit still faster and stronger in its evolution. By late Friday into Saturday, the model trends indicate this feature will likely lift across the Southwest coast as another compact low over the eastern Gulf of Alaska moves west to Prince William Sound. Still, there are plenty of discrepancies in timing and strength of these features between the models, limiting forecast confidence by the weekend. For the Bering, Models are struggling with the evolution of a complex low with multiple centers of circulation as its moves from Kamchatka to the central Aleutians by Friday. The NAM, GFS, and EC all show a similar trend with this feature, but, again, there are timing and position issues with the multiples lows, keeping forecast confidence average at best by Friday. && .AVIATION... PANC...VFR ceilings and visibility will generally persist from mid-morning today through early Thursday morning as a frontal system lifts away from the airport complex early this morning. Occasional MVFR / IFR ceilings are possible until 15z as a mix of light rain and snow comes to an end. MVFR ceilings are then expected to return by early morning Thursday as a second, weaker trough moves up Cook Inlet toward Anchorage. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2: Today through Thursday Night)... Southcentral is rapidly approaching a much quieter period of weather for most of the area. Note that quieter weather doesn't necessarily mean quiet. Here is what we are looking at: The last vestiges of the powerful storm of the past few days are crossing the area this morning. The last of the snow has moved through Anchorage, and the back edge of the snow will steadily progress north across the Mat-Su over the next few hours. Mountain snow showers across the Alaska Range, Talkeetnas (including Hatcher Pass) and coastal Chugach Mountains will persist through the day, with potential for isolated snow showers into the Copper River Basin through the day. Behind the low, we are seeing widespread low stratus and patchy fog developing over portions of the western Kenai Peninsula this morning. The fog will persist through the morning, and quite probably longer. For other areas, the skies are clearing, and most areas should see at least some broken sunshine this afternoon. Temperatures are at or slightly above freezing in most areas of the Cook Inlet Region. After 1-3 inches of snow overnight, the above freezing temperatures will keep conditions very slick through the day today, followed by cooling back into the 20s tonight resulting in refreezing. Elsewhere, the onshore southerly flow persisting into tonight will keep upslope snow ongoing as well through Thompson Pass through tonight. However, the warm southerly flow should keep the consistency of the snow wet and heavy, thus despite the winds, any blowing snow should not result in significant reductions in visibility. On Thursday, the break in the weather will end on Kodiak Island. A northwestward moving low will track well south and west of the island during the day. This will lead to strong southeasterly onshore flow developing across the island, leading to periods of heavy rain through the day, with snow in the mountains. There is some uncertainty on how far north the extent of that precipitation will go, including as far north as the Homer area and the southern Kenai Peninsula. This may result in rain shower activity around Homer, but that is just a chance right now, and it's definitely possible it stays dry there as well. The easterly onshore flow will develop well north of the center, thus it is far more likely that upslope precipitation (rain at the lower elevations, snow in the mountains), will develop across the eastern Kenai Peninsula. Precipitation there is not expected to be particularly heavy, but may be steady at times. Elsewhere, dry weather will continue as an odd east to west oriented upper level ridge moves over Southcentral through Thursday. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2...Wed through Thu night)... A long-lived storm from the central Bering is still trekking toward Kuskokwim Delta to beyond YK-Delta by this evening through overnight tonight. Shortwaves associated with this system combined with cold air advection behind the storm will enhance the potential for increased snowfall tonight, then tapering off by Thu morning. Meanwhile, cloud remnants from this same storm and the onset of another storm from the North Pacific, combined with cold air advection from the eastern Bering, will most likely favor snow over rain across Bristol Bay and AKPEN through the forecast period. However, a slight chance of rain is feasible should warm temperatures rise from the Gulf as the warm air boundary pushes northward and west of the region through Thu night. The mix snow to rain pattern will basically keep the forecast period a bit cooler but relatively quiet in the next couple days. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2...Wed through Thu night)... The storm near Pribilof Islands will begin to lose its energy as it drives closer to Kusko Bay this evening. The pattern for snowfall continues across the Aleutians as cold air advection and trailing cloud remnants from the storm passes through the Aleutians today and tonight. The next complex storm from the Northwest Pacific has already entered the southwestern Bering early this morning. This storm will elevate winds, seas, and snowfall through Thu morning before exiting the Aleutians Thu night. An upper level ridge follows right behind this storm, with the next frontal system approaching the western Bering Thu night. Clearly, more weather is expected over the Aleutians especially along the western and central Aleutians by Thu and Thu night. && .MARINE (Days 3 through 5: Friday through Sunday)... Gulf of Alaska: Models are in relatively good agreement that a low will track into the eastern Gulf, keeping quiet conditions over the western and central Gulf through Saturday morning. By Saturday afternoon, models all agree that a North Pacific low will track into the northern Gulf. However, there is still some uncertainty in the strength of this system, which will likely remain below gale force before moving inland by Sunday morning. Behind this low, a strong front enters the western Gulf through Sunday afternoon, which could bring a round of gale force winds to the region. Bering Sea: Models are struggling with the placement of a low over the eastern Bering/AKPEN region on Friday afternoon, which could see an area of gale force winds, before quickly weakening Friday night. A much stronger, strengthening system farther west will be the main feature to focus on starting Friday afternoon. The associated gale force front will move over the central Aleutians through Saturday morning. However, there is still model uncertainty as to how strong this system will get as it moves eastward through Saturday afternoon. Models agree that there will be high end gale force winds, with the potential to even bring storm force winds into the forecast area. && .LONG TERM FORECAST (Days 3 through 7: Friday through Sunday)... The long term forecast starting Friday looks to start with continued persistence with a deep vertically stacked low over most of the Bering, with weaker but quickly developing lows in the Gulf. With deep southerly flow over most of the Mainland and continued active weather, confidence is good that temperatures should remain above normal with an increased risk for storms in the Gulf through the upcoming weekend. && .AFC WATCHES/WARNINGS/ADVISORIES...
