Area forecast discussion, Dec 22, 5:19 AM AKST, 10 hours 28 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 519 AM AKST Tue Dec 22 2020 .ANALYSIS AND UPPER LEVELS... The longwave pattern features a broad trough over the Bering and a ridge axis bisecting SE Alaska and the Yukon Territory. There are numerous shortwaves riding up the back side of the ridge and distinct upper level closed lows near the Pribilof Islands and over NE Russia. The leading edge of the jet is entering the Gulf Of Alaska while the jet core of 170 knot is south of the Aleutians. At the surface there is a an mature front over the Bering and another mature front making headway across the Gulf. On satellite imagery, there is a distinct tropical connection with the low in the Gulf. The deep fetch of moisture extents from just east of Kodiak to an area north of Hawaii. && .MODEL DISCUSSION... Synoptically, models are in good agreement through 36 hrs. There are some minor difference with the onset and end time of precipitation. As usual, the thermodynamic parameters of the models are slightly off which could have implications for p-type (snow vs. rain). This is most noticeable over Cook Inlet and Prince William Sound. In the past 4 days, the model agreement has improved significantly over the Bering, the North Pacific and in the Gulf Of Alaska. && .AVIATION... PANC...There is a frontal boundary moving across the aerodrome. Expect several decks of cloud layers. Even though the cigs will decrease, the current thinking is that the cloud coverage will stay above VFR minimums. The main impact to the airfield will be low level wind shear today. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2: Today through Wednesday Night)... The very active storm pattern across Southcentral continues into Wednesday, with a much needed and well-deserved break in the weather expected starting Wednesday night. For the Anchorage area, the High Wind Warning remains in effect until 6pm this evening. While winds have been slow to come up so far this morning, there are already indications upwind across the eastern Kenai Peninsula that the period of highest winds is arriving with Portage Glacier recently reporting an 82 mph gust. Nevertheless, the model guidance has backed off a little bit on the peak winds, and as such the expected peak wind gusts have also been refined down as well. Nevertheless, this still is expected to be a very impactful event with frequent gusts well over hurricane force for Turnagain Arm and higher elevations, with even a few hurricane force gusts possible over the Lower Hillside. The peak winds still look to be between now and noon, as the front causing the winds barrels north across Southcentral. This afternoon into tonight, the winds will diminish a bit, but will still remain strong with gusts approaching 75 mph still possible at higher elevations. The gusty winds are also expected to increase across much of the Matanuska Valley today. Palmer has already had a peak wind gust earlier this morning of 50 mph. The gusts here too will peak later on this morning, but will remain gusty into tonight. The High Wind Warning also remains in effect for the Eastern Kenai Peninsula, specifically through Portage Valley and Eastern Turnagain Arm, with Portage Glacier already getting hurricane force gusts with the peak winds still to come later this morning. The Blizzard Warning has been an interesting story. It remains in effect, but has been trimmed back to 9am. Most of the observing stations along the Seward Highway were well above freezing earlier yesterday evening, suggesting rain was occurring far sooner. However, since then temperatures have been dropping and Portage Glacier has changed back over to snow. Nevertheless, warmer air is making its way towards the area behind the front causing the strong winds, and since temperatures along nearly all of the Seward Highway are at least at, and in many cases still are above freezing, it stands to reason the warmer air coming in with the front later this morning should turn all of the precipitation over to rain up through Pass level. That said, it's likely there will be localized changes back and forth between rain and snow through this morning, and the blizzard conditions are still likely occurring through Turnagain Pass, so travel remains strongly discouraged through this morning. A secondary area of low pressure still well south of the Gulf will race northward towards Southcentral, reaching the coast of the Kenai Peninsula somewhere between Seldovia and Seward this evening. The low center will then hug the coast and move into Prince William Sound late tonight, then move inland and dissipate Wednesday morning. This will have a number of effects as it happens: First, the High Wind Warning for the Cordova area remains in effect, because that low will push the hurricane force barrier jet inland for a few hours before the strongest winds rapidly diminish. This is likely to occur within a few hours of midnight tonight. Second, this low track will keep the Cook Inlet region on the "cold" side of the low. However, by tonight there will be very little in the way of cold air to work with, as the warming flow expected all day today will scour it all out. Therefore, as with a few storms already this winter season, temperatures will be right near freezing tonight into Wednesday morning with a good likelihood of occasionally heavy precipitation. However, what form that precipitation takes is still very much in doubt, as a degree or two will make all the difference between blowing snow and a driving cold rain. The eastward trend in the low track does favor a colder solution and snow, and thus, the forecast reflects the still highly uncertain expectation that most of the precipitation tonight into Wednesday morning falls as snow across the Cook Inlet region. 1 to 3 inches of snow are possible for a few hours, but due to the fast moving and heavy nature of the snow band producing the accumulation, they will come down quickly. Below freezing temperatures will also likely cause many slick areas, due to refreeze from today's melt combined with the snow. The snow rapidly shifts north through the day, such that by lunchtime Wednesday, most of the snow should be up in the Susitna Valley with Anchorage and points south drying out and maybe clearing the skies a bit Wednesday afternoon. The low may produce periods of heavy snow through Thompson Pass and the mountains north of Cordova tonight through Wednesday as well, with the upslope persisting into Wednesday night in those areas. For the rest of Southcentral, Wednesday night and beyond is looking pretty quiet, with seasonable to slightly above average temperatures heading into Christmas. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)... The evolving progress of the mix rain/snow precipitation type (P-type) is still valid as southerly winds continue to bring warm temperatures over the area, leading rain across AKPEN, Bristol Bay and farther inland but well south of Kuskokwim Valleys, and portions of Kuskokwim Bay before noon today. Meanwhile, steady light snow will continue north of Chuilnuk Mountains and around Sparrevohn this morning. The cold air advection from the stacked low over the Bering will reach the coastline by this evening if not sooner. The snow trends into Wed as the freezing level advances eastward and across Southwest Alaska, and the amount of snow will decline after tonight. Essentially, the amount of snow accumulation in the next two days will range from 1 to 4 inches near surface, but a bit high at higher elevation between 6 to 8 inches today. Fresh to strong southerly winds and higher gusts inland will gradually diminish by this afternoon, but not so for AKPEN. A shortwave embedded within the westerly flow south of the low from the Bering will maintain elevated winds and snow showers over much of AKPEN through Wed night. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)... No new news since yesterday about the steepening stacked low over the Bering. Limited forward motion is expected of the low until Wed morning when it finally picks up speed while moving toward Kuskokwim Bay through Wed afternoon. A stubborn upper level ridge northeast of Southcentral will stick around for another day until it starts weakening by Wed morning, which leads the circulation to pass right through Y-K Delta by Wed night. Light freezing spray will cover much of central Bering and a portion of Kuskokwim Bay through Wed night. Heavy freezing spray will likely be found farther west of Nunivak and Pribilof Islands, with only a minimal coverage south of Kipnuk in the next couple days. && .Marine (Days 3 through 5: Thursday through Saturday)... Gulf of Alaska Models have come into better agreement on the track of low moving out of the North Pacific and then towards the AKPEN on Thursday, but there continues to be disagreement on the strength. There remains upside risk to the southerly winds currently in the forecast, with gales looking possible across the western Bering. On Friday/Saturday fairly quiet conditions are expected with good forecast confidence. Bering Sea: On Thursday models continue to struggle with the placement of a compact storm force low, with the GFS bringing this low through the central Aleutians, while other models track this system mostly south of the Aleutians. Our forecast sides with the further south track,keeping lighter winds in across the Aleutians. On Friday a front pushes into the western Bering/Aleutians, and a few areas of Gales appear possible. On Saturday a deepening storm system looks to set up across the western Aleutians, but there are significant model differences as to how quickly this storm strengthens. There may be significant upside risk to winds across the eastern Bering on Saturday if the stronger solutions work out. && .Long Term (Days 4 through 7/: Friday through Monday)... On Friday models have come into better agreement on the track of a North Pacific low, with good agreement on this next storm system heading towards the AKPEN, bringing another wintry mix to southwest Alaska and Kodiak. A gale force front looks to push into the western Aleutians at the same time. On Saturday the AKPEN low mostly dissipates. Meanwhile, a storm system begins to rapidly intensify across the western Aleutians with the potential for some storm force winds setting up across the central Aleutians along with plentiful rain. On Sunday most models show this Bering/Aleutians storm becoming fully mature and retrograding north and west towards the Kamchatka Peninsula while unsettled weather continues across the Bering and Southwest Alaska. Model consistency disintegrates heading into Monday, but the general idea of an active pattern across the Bering and relatively quiet weather across Southcentral should hold. && .AFC WATCHES/WARNINGS/ADVISORIES...
