Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 453 PM AKDT Fri Sep 18 2020 .ANALYSIS AND UPPER LEVELS... The low which brought abundant rain and wind to southern Alaska on Thursday has made its way north, reaching the Seward Peninsula. The main impacts to both the Southwest and Southcentral are now from multiple shortwaves south of the low center, traversing from the Bering Sea across the southern mainland. Coupled with atmospheric instability created when colder air aloft moved in behind the low, these short-waves are maintaining showery and gusty conditions across the region today. Out over the eastern Aleutians an upper-level shortwave with a weak surface rotation is traveling quickly eastward toward the Gulf of Alaska. Impacts from this compact low are minimal, with some small craft winds, low clouds and light rain in the Dutch Harbor area. Lastly, a low near the Kamchatka Peninsula is strengthening as it tracks toward the Aleutian chain. This will be the next big storm system and focus of the forecast for the next few days. && .MODEL DISCUSSION... Models are in good overall synoptic agreement for the next few days. There is some disagreement with the interaction of a short- wave trough (or multiple short-waves) approaching Southcentral Saturday night and the interaction with the low over the Gulf at this time. All solutions indicate that some moisture will be pulled northward and a deformation band of heavier precipitation will form. However, the location of this band varies from Prince William Sound all the way west to the Anchorage area. Thus, confidence in the precipitation forecast for these areas is low. Meanwhile, models have locked on to a solution with the strong low tracking eastward along the Aleutian chain this weekend, then moving into the Pacific and Gulf early next week. && .AVIATION... PANC...VFR conditions will persist. Gusty winds look like they will begin to die down some time Saturday morning as the influence of the low over Northwest Alaska finally wanes. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: Fri afternoon through Mon afternoon)... An upper level low in place across much of the state will allow for some unsettled weather to continue over Southcentral. With a weak trough in place over the area this afternoon, showers are moving in across the northern Gulf and coastal areas of Prince William Sound. Meanwhile, the upper level low to our west continues to move eastward, and will bring a much stronger trough to the area by Saturday morning. While models struggled a bit over the last few days with the track of this low, there has been much better agreement today with a more eastward track, though the low center will remain over the Gulf. By Saturday night, precipitation will fill in across Southcentral with the greatest amount expected along the northern Gulf coast. As the low departs on Sunday, conditions will improve with just a few lingering showers. The next system to impact Southcentral will arrive from the west Sunday night. This looks to be a much stronger low with a leading front bringing winds and rain to Kodiak Island Sunday night before lifting to the northeast by Monday. Another bout of gusty southeasterly winds and rain is looking increasingly likely for the start of the next workweek. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)... (Tonight through Monday) Cold air advection will continue for another day or two in response to a shortwave and an upper level trough running through Southwest Alaska from the north of Yukon Bay. This pattern will yield to cooler overnight temperatures, with isolated showers passing through the region over much of the forecast period. As a result, anticipate a relatively quiet forecast period with only minimal showers over the area. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)... (Tonight through Monday) A highly anticipated circulation from the Northwest Pacific will bring gales Saturday and Saturday night over much of the Bering Sea, including western and central Aleutians. At the same time, the gusts will potentially build up until it reaches severe gale conditions between Sunday and Sunday as the center of the low pressure system passes southeastward and beyond Dutch Harbor. Hazardous wave heights will potentially reach up to 20 to 25 ft along the west and south of the Aleutians west of King Cove, meanwhile, light to steady stratiform rain will pass through much of the forecast area through the forecast period. Overall, wet pattern will predominate local conditions over the area in the next coming days. && .MARINE (Days 3 through 5/Monday through Wednesday)... A very large storm system will make its way from the vicinity of the eastern Aleutians/southern Alaska Peninsula on Sunday night into the Gulf of Alaska and northeast Pacific by Monday night. Widespread gales are likely across much of the region from the eastern Bering Sea to the Gulf of Alaska Monday through Tuesday. There is also potential for a secondary surface low to form over the Gulf sometime Tuesday. If this does occur, then would likely be at least a small area of storm force winds. The system does look like it will begin to weaken on Wednesday and exit toward Southeast Alaska. Thus, winds should finally begin to die down. && .LONG TERM FORECAST (Days 4 through 7/Tuesday through Friday)... The main focus to start the extended period on Tuesday will be a very large storm system tracking from the Bering Sea to the Gulf of Alaska and northeast Pacific. Based on this storm track, rain and wind will clip Bristol Bay and then impact Kodiak Island and the Gulf coast. Further north areas of Southwest and Southcentral Alaska will remain mostly dry with seasonable temperatures. There is some uncertainty in low position over the Gulf and in whether a secondary low will form and enhance winds/rain somewhere in the Gulf. However, do expect this system to weaken and exit eastward Wednesday through Thursday. In general, after the impacts of that system diminish, the weather looks relatively quiet across the forecast area through Thursday. As we head to Friday there is fairly large model spread in the details of specific storm systems, but there are some commonalities in the upper level pattern. It looks like an Arctic trough (or multiple short-waves) will dig south across the Bering Sea and into the north Pacific, causing the upper level flow to amplify. This would then favor cyclogenesis over the Pacific south of the Alaska Peninsula, with a storm track into the Gulf, which would bring a return to storminess over the Gulf on up into Southcentral Alaska. Stay tuned. && .AFC WATCHES/WARNINGS/ADVISORIES... PUBLIC...NONE. MARINE...Gale Warning 170 172-178 411-413.
