Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 440 AM AKDT Fri Sep 22 2017 .ANALYSIS AND UPPER LEVELS... Two upper level lows, one centered just inland of Norton Sound, and a secondary weaker upper level low south of Dutch Harbor are the primary drivers of this morning's weather pattern across Southern Alaska. Cooler air is slowly filtering in, especially in Southwest Alaska. East of the upper level lows, much warmer, moist air is being replaced by the cooler air mass north of it. This clash of air masses, along with some upper level forcing, is the driver for the ongoing precipitation occurring over a good portion of the area. The upper low, while the dominant feature in the upper level pattern, is not associated with particularly cold air in the lower levels of the atmosphere, and thus, precipitation has broadly remained light as baroclinicity is unimpressive. && .MODEL DISCUSSION... The models are tightly clustered through much of the next two days as a nearly stationary front draped across Bristol Bay and extending northeast into Southcentral, and a low working its way eastward moves into the western Gulf by Saturday. All of the models agree on this scenario well. By Sunday however, there is more divergence between the models as to how the low moves northward into Southcentral. Thus, by Sunday the model differences especially in precipitation start to appear, and the primary question for Southcentral becomes how much precipitation gets over the Kenai Mountains into the western Kenai Peninsula, Anchorage Bowl, and the Mat-Su Valleys. The NAM and EC had the best agreement in the short-term so those were the models used going into Sunday. Forecast confidence is high. && .AVIATION... PANC...Off-and-on rain will be present throughout the day, occasionally lowering visibilities and ceilings to MVFR. Light winds will persist until this evening, then building surface ridging along the coast and troughing along the Alaska Range cause the Turnagain Arm Jet to potentially move into west Anchorage and PANC. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... A frontal boundary extending along the spine of the Alaska Peninsula and up to Cook Inlet will remain nearly stationary through this evening. Surface waves riding up the front combined with a steady stream of upper level waves moving through the same general area will continue to produce steady rain from the western Kenai Peninsula up to Anchorage and the Mat-Su. Precipitation will be more showery east of the main forcing, across the Gulf and on up to Prince William Sound. These steady state conditions will begin to change tonight as the remnants of a low south of the Aleutians tracks to the western Gulf out ahead of a digging short-wave over the eastern Bering Sea. This will cause flow to back toward the south and southeast, which in turn will push the northern part of the stationary front westward. The strengthening low level southeast flow will cause a downslope hole to open up from the western Kenai to Anchorage and the Mat Valley be early Saturday, bringing an end to the rain in these areas. Expect strong upward vertical motion to then develop ahead of the digging trough on Saturday as it rotates into the Gulf and becomes negatively tilted. This will lead to heavy rain over Western Prince William Sound as well as the west side of Cook Inlet and western Susitna Valley. This will also help re-invigorate a weak surface low which moves into the Gulf, leading to a Gale force front along the north Gulf coast Saturday afternoon. The low will ultimately track to the vicinity of the Kenai Peninsula Saturday night into Sunday, which will cause downslope flow to weaken and likely lead to rain moving back into the population centers. The heavy rain over the weekend will add to high water levels on Kenai Lake and Kenai River produced by the release of water from the Snow glacier dammed lake. Thus, a Flood Warning remains in effect all the way through Monday. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)... A stalled front draped along the western Alaska Range, to eastern areas of Bristol Bay, to the Alaska Peninsula remains through Saturday then lifts slowly north. Another low pressure system develops within the trough and brings higher chances for rain across the Kuskokwim Delta on Saturday and then dives to the Peninsula on Sunday. The general flow across the southwest mainland and Peninsula will be out of the north through Saturday then switches to a southerly direction as the surface low associated with the front lifts through the Kuskokwim Valley. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)... A cooler weather regime is on tap through the upcoming weekend as a cold air mass advects from the northern Bering along the backside of a trough along the west coast of the mainland. The pattern stays on the drier side as a ridge across the western Bering slides south. Overall, winds are expected to be low impact with small craft northerly winds along the the central and eastern waters. && .LONG TERM FORECAST (Days 3 through 7)... Beginning the extended period forecast Saturday evening, with an upper level low tracking southward over the eastern Bering and bringing waves of North Pacific moisture northward toward the Gulf of Alaska and southern Mainland through the early part of next week. This pattern will support wet weather across the region into Sunday afternoon, as a front will move toward the Gulf Coast. Gusty winds are also expected to increase along the Gulf Coast Saturday afternoon through Sunday morning, as the front pushes up along the northern Gulf coast. Showers will begin to taper off over much of the southern mainland by Monday morning, and remain slightly drier through Tuesday morning when the next system begins tracking into the Gulf. Precipitation will begin to spread northward back into the southwest mainland and northern Gulf Coast Tuesday afternoon, as a North Pacific low tracks northward into the western Gulf. There is some disagreement between the models with regards to the track and timing of this system, which impacts when the precipitation spreads further inland. Currently the forecast is trending toward precipitation moving further inland overnight Wednesday into Thursday morning, with the low tracking inland over the Kenai Peninsula. && .AFC WATCHES/WARNINGS/ADVISORIES...
