What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Anchorage, AK wrote its last area forecast discussion before this gale warning went out at Feb 15, 4:53 PM AKST, 11 hours 9 minutes earlier.
Area forecast discussion, Feb 15, 4:53 PM AKST, 11 hours 9 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 453 PM AKST Sat Feb 15 2020 .ANALYSIS AND UPPER LEVELS... A zonal polar jetstream which extends across the Aleutians and through the southern Gulf of Alaska is in the process of amplifying. The subtropical jetstream remains south of 50N across the North Pacific. Surface high pressure extends southwestward across mainland Alaska from northern Yukon Territory. A large area of low pressure approximately 300 nm northwest of Saint Paul is slowly moving northward. A shortwave trough is moving through the Kuskokwim and Bristol Bay bringing snow to the area with warmer temperatures along the coast. Another area of light snow is moving eastward through the central Gulf and Prince William Sound. && .MODEL DISCUSSION... Models are consistent with the overall synoptic pattern for Sunday and Sunday night. However, some discrepancies arise on Monday with respect to the deep low approaching southwest Alaska. Even so, solutions are at least grouped together and all models depict a storm force low. As a result, will overhaul the forecast for the eastern Bering and Southwest Alaska to better depict the impacts of this storm. Major model disagreement begins on Tuesday, particularly with development and track of a surface low across the Gulf of Alaska. Conditions are favorable for cyclogenesis, as a high amplitude trough progresses eastward underneath the western Alaska Low and swings into the Gulf. Arctic air accompanies it into the Gulf. There are differences with individual short-waves moving through the larger trough as well as with the tilt of the trough. For now, will not completely buy off any particular solution and wait until there is better agreement before making any significant changes to the forecast. Forecast confidence is high for Sunday, moderate for Monday and low Tuesday onward. Despite the differences in model output, we are confident that the overall weather pattern will be active with impactful weather likely across much of the forecast area. As is typical, higher resolution models were favored for small-scale localized effects in this forecast package. && .AVIATION... PANC...VFR conditions and light winds will persist. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... An amplifying pattern will bring a warm front across Kodiak Island tonight. This warm front will bring moisture and warmer temperatures, so the southwestern part of the island will see rain while Kodiak City will start off as snow before transitioning over to rain. As this front moves northeast across Southcentral through Sunday into Monday night, snow chances will increase for coastal areas, higher elevations and the Susitna Valley. As the front propagates into the central Gulf, a barrier jet will set up along the northern Gulf. The southeasterly flow associated with this barrier jet will make it's way into Prince William Sound. This is an indicator of the beginning of a Turnagain Arm wind that will start early Monday morning and carry into Tuesday. As the wind ramps up, warmer temperatures will make their way into the Anchorage Bowl with the highest temperatures expected on Tuesday. This flow pattern also indicates downsloping as the mountains on the windward side of this flow pattern receive the bulk of the precipitation. Areas on the leeward side, including Anchorage and the western Kenai Peninsula look to remain mostly dry with only up to a 20 percent chance of precipitation for these areas. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3: Tonight through Tuesday)... Major changes were made to the forecast this afternoon, in response to improving agreement between the models on the track and likely impacts resulting from a strong low moving north up the west coast from the North Pacific. More on that below. The light snow ongoing across much of the Kuskokwim Delta, Lower Kuskokwim Valley, and portions of Bristol Bay this afternoon are the result of a dying front moving across the area. Visibilities across the area should gradually improve overnight. The break between the systems will be brief during the day Sunday. Late Sunday afternoon, a warm front will move south to north across the area. This front will increase the winds, particularly across the Kuskokwim Delta. Much of the rest of the area will pick up 1 to 3 inches of snow with this front, but it will be a precursor to the more active weather alluded to above. The front itself will also fall apart and weaken overnight, but snow showers are likely to persist across the Kuskokwim Valley. With the windiest conditions expected along the Kuskokwim Delta coast, it is those areas where visibilities are most likely to drop to one half mile or less late Sunday afternoon and evening. Following right behind this front will be the strong low mentioned above that will cause much of the hazardous weather that will impact Southwest Alaska. A second warm front at the leading edge of the low will begin the precipitation over Southwest Alaska. The warm air with this feature will be enough to cause any snow that begins at the onset to mix with and change over to rain across much of Bristol Bay, mainly after midnight Sunday night. Strong southeasterly winds through the gaps, particularly across Lake Iliamna, will lead to downsloping which will shut off the rain or make it light from Iliamna through King Salmon. The main precipitation will ramp up across the Kuskokwim Delta a bit later, after midnight. From Kipnuk and Kuskokwim Bay south, the snow may mix with rain, especially Monday morning. Elsewhere from Bethel north and west, snow will be the sole precipitation type. Winds will increase markedly with this low, especially along the coast. A Winter Storm Watch for blizzard conditions is in effect west of Bethel. The watch begins Sunday afternoon, but that is with the aforementioned warm front bringing some wind and snow, but not enough where blizzard conditions are expected. Late Sunday night, with the main low, is when the worst conditions west of Bethel are possible. From Monday afternoon on, there are some significant differences between the models on the storm track. However, the most common one involves the low center stalling off the coast. While snowfall rates will be much lesser Monday afternoon and Monday night at the coast, the gusty winds and already fallen snow will keep blowing snow advisory conditions ongoing throughout the night and into Tuesday morning. Cold air will quickly wrap around the low by Monday evening, which will transition all of Southwest Alaska back to snow. The leading front, now occluded Monday evening could possibly result in a deformation band developing for Bristol Bay and the Lower Kuskokwim Valley. This could bring a few inches of snow to many of the areas that changed over to rain or didn't get much precipitation at all. This band moves north and east across the Alaska Range Monday night. As the weakening primary low very slowly drifts eastward into Southwest Alaska on Tuesday, widespread snow shower activity is likely to persist throughout the day, resulting in additional minor accumulations for the entire area. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3: Tonight through Tuesday)... A strong low over the northern Bering keeping active weather ongoing for much of the basin will continue gradually weakening. A pair of compact North Pacific lows follows behind it. Both are capable of producing small areas of gale force winds. The first will track just east of Shemya, causing some snow or a rain/snow mix along with windy conditions through Sunday night. The low will then accelerate quickly south and eastward back into the North Pacific by Monday morning. The second low tracks east of Nikolski late tonight then then will move to near the Pribilofs as it weakens into a trough Sunday night. Yet another low will follow behind this second one. This next low will be the main hazardous weather maker for portions of the area. As the low track near Dutch Harbor Monday night, it will be rapidly strengthening. Cold air streaming in south of the low will lead to rapid pressure rises, causing high winds in the waters around the eastern Aleutians. High Wind Watches have been issued for the Alaska Peninsula and Eastern Aleutians, with the primary threat area expected from Dutch Harbor through King Cove. South to southwest winds gusting to 80 mph are possible for a brief period late Sunday night. As the parent low quickly lifts northward away from the area, the high wind threat will rapidly diminish Monday morning. The low will then sit and spin somewhere in the area between the Pribilofs, Cape Newenham, and Nunivak Island through the day Monday. In addition to widespread gales and small areas of storm force winds, it will also draw down much colder air across the central Bering, including around the Pribilofs. This will likely cause blowing snow conditions across the Pribilofs. How severely visibilities are reduced will entirely depend on the exact track of the low, which remains uncertain. Thus, while no hazardous winter weather products have been issued for the islands, residents should remain on alert for blowing snow conditions and cold temperatures returning to the islands. The low slowly moves into the southwest mainland during the day Tuesday, as another front moves into the western and central Aleutians late in the day on Tuesday. && .MARINE (Days 3 through 5/Tuesday through Thursday)...The extended forecast begins on Tuesday with a deep system in the eastern Bering Sea. Widespread gales can be expected over much of the Bering with this system as well as freezing spray concerns. Another system enters the area on Wed/Thur and looks to come west to east, possibly tracking just south of the Aleutians. No matter the storm track, the secondary system will bring a colder air mass to the Bering Sea along with freezing spray concerns and prolonged northerly wind. && .LONG TERM FORECAST (Days 4 through 7/Wednesday through Saturday)... An active storm pattern will be taking shape in the extended period. Guidance is pointing at a slightly different track than what we've been experiencing, just south of the Aleutians into the Gulf of Alaska as opposed to the north Pacific into the Bering Sea. The setup will bring more active weather to Southcentral Alaska. The focus for this time period will be a front stalling out from northwest to southeast over the mainland/Gulf of Alaska on Tuesday. Guidance is pointing to the development of strong low pressure system along this boundary in the Gulf, tracking into Prince William Sound. The main concerns with this track will be snowfall potential in the Anchorage and Matanuska Valley, as well as Valdez area. Behind that system, a system from the Aleutians will move into the Gulf of Alaska late in the week. No matter the exact storm track, look for another shot of Arctic air coming back into the area. && .AFC WATCHES/WARNINGS/ADVISORIES... PUBLIC...High wind watch 181 185. Winter Storm Watch 155.
