What forecasters said that day
The local office's own words before this red flag 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 red flag warning went out at May 20, 5:01 AM AKDT, 10 hours 9 minutes earlier.
Area forecast discussion, May 20, 5:01 AM AKDT, 10 hours 9 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 501 AM AKDT Fri May 20 2022 .ANALYSIS AND UPPER LEVELS... Longwave high pressure ridge has shifted entirely over mainland Alaska this morning with the ridge axis extending from Talkeetna southward across Prince William Sound and into the Gulf. This continues to promote warm and dry conditions across Southcentral with a layer of marine stratus trapped over the northern Gulf. High temperatures could reach 70 degree Fahrenheit for the first time this year across Southcentral. Meanwhile, a North Pacific upper low continues to lift northward toward the Aleutians with high clouds already overspreading interior Southwest from King Salmon to Bethel. Further south and west the front is promoting scattered rain showers over the Eastern Aleutians, including Dutch Harbor where perhaps up to a half an inch of rain may fall through tonight. Regarding winds, east southeasterly gales will become increasingly common throughout the day on the Pacific side as well as the Bering side of the Eastern Aleutians and Alaska Peninsula as the front continues to lift northward on Friday. Seas, however, are forecast to stay below 20 feet. && .MODEL DISCUSSION... There remains good model agreement through the next 48 hours. A broad trough of low pressure is overspreading the Aleutians this morning with a front to eventually stretch into the Gulf by Sunday. If any discrepancies can be found, it's toward the end of the period with the development of a triple point low over the western Gulf early Sunday morning. There are some minor differences in its placement and strength though not enough to reduce the forecast confidence at this time. && .AVIATION... PANC...VFR conditions will prevail through Saturday morning while a ridge of high pressure remains over the region. The development of Turnagain Arm winds is expected late this afternoon and evening. The strongest winds will remain offshore of Anchorage; however, some bending of the winds into PANC is expected with southeast gusts up to 15 knots or greater. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3; Friday through Sunday)... Very little change in the overall thinking for the forecast. More warm and dry weather for the interior of Southcentral today but a front will move over Kodiak Island and bring rain and strong winds. It still looks like some Turnagain Arm winds will move over Anchorage this afternoon and evening with some Knik River winds developing near Palmer. That will bring in a little more afternoon wind than we have been seeing for Anchorage and Matanuska Valley so that is a change from previous days. The other nit of a change is a little unexpected and that is the large area of fog and stratus that developed in the northern Gulf of Alaska yesterday and persists into today. This stratus likely developed in response to the surface ridge along the northern Gulf coast enhancing ahead of the front. This increased the subsidence allowing the stratus and for to develop. Currently it has moved into Seward and Cordova and is starting to make inroads into Prince William Sound. The stratus is also pushing westward to Kennedy entrance of Cook Inlet though further progress is hard to see as higher clouds are now moving in over that area and obscuring the satellite imagery being used to track the stratus. It is likely that the approaching front will start to mix enough of the atmosphere to lessen the stratus, but it remains to be seen if it can fully dissipate today or even tomorrow. Expect increasing high clouds over Southcentral on Saturday with the clouds lower by Sunday due to the front weakening the ridge. This will also cool temperatures over Southcentral especially on Sunday. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3: Today through Monday)... A ridge of high pressure will slowly move east as a front extending from a low in the southern Bering lifts northeastward. Southeasterly winds have increased along the Alaska Peninsula in response to a tightening pressure gradient between the mainland high and Bering low. Winds will continue to increase throughout today through Kamishak gap and the eastern corridor of Bristol Bay, including Koliganek and New Stuyahok. Along with increasing winds, a decent plume of moisture and warmer air will advect from south to north ahead and along the aforementioned front. Chances for light rain are expected to increase this afternoon/evening for the Alaska Peninsula and Southwest regions. Due to the strong southeasterly flow, rain associated with this system will be mostly limited to upslope favored areas on the Kuskokwim and Aleutian Mountains. Therefore, the bulk of the precipitation will be concentrated along the coastline, while the interior valleys stay relatively dry. Light rain will continue for most of the coastal areas as we head into the beginning of the work week with another low pressure system tracking near the western Gulf of Alaska by Sunday. Models are still trying to resolve this feature and how it will interact with the dominating high pressure over the Mainland, so uncertainty increases by Monday. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3: Tonight through Monday)... Areas of low stratus and patchy fog under a ridge of high pressure blanket most of the Bering Sea and Aleutian Islands. As the ridge axis shifts slowly east, an area of low pressure is expected to lift northward near Dutch Harbor. The aforementioned low's front will continue to bring gale force winds with higher gusts for the central and eastern Aleutians while slowly diminishing tonight as the low weakens and becomes quasi-stationary south of Atka. A decent plume of moisture and warmer air aloft will advect northward in correspondence with the front bringing rain to the central and eastern Aleutians before pushing westward between Kiska to Attu by Sunday afternoon. The aforementioned low is expected to remain quasi-stationary through the beginning of the week, therefore, keeping chances of light rain over much of the region into Monday. &&.MARINE (Days 3 through 5: Sunday through Tuesday)... Gulf of Alaska: A front enters the Southern Gulf Sunday, and moves across the Gulf through Monday. A surface low will move over Kodiak Island by Monday. Gusty Easterly winds with the front stretch across the Gulf, with areas of gales over Kamishak Bay, Shelikof Strait, Sitkinak and along the Alaska Peninsula coast, diminishing Saturday. An Easterly gale force barrier jet forms along the North Gulf Coast. Seas to over 10 feet possible east of of Kodiak Island. Cyclonic flow will persist over the Gulf for the remainder of the forecast period. Bering Sea: A mature low remains South of the Aleutians through Tuesday. Widespread gusty winds expected for the North Pacific low, with areas of gales from Bristol Bay into the Central Bering, diminishing Sunday. Seas to 14 feet on the Pacific side of the Alaska Peninsula, subsiding Saturday, and 10 feet or less over the Bering, subsiding Monday and Tuesday. && .LONG TERM FORECAST (Days 4 through 7: Monday through Thursday)... A Rex Block pattern is likely during the extended period as upper level ridging extends across the central/northern Bering and into northern Alaska. At 500 mb there are 2 closed lows south of the chain and GFS keeps those lows south of the chain through Friday. The ECMWF shows a similar evolution of the mass fields at 500 mb this forecast period, but these two models are definitely not a clone of each other. Expect an area of persistent ridging but also expect a lingering closed low over the Gulf Of Alaska. Sensible weather-wise the GFS keeps positive height anomalies over mainland Alaska this forecast period which will translate to warm temperatures at the surface and the continuation of snow melting. With the closed low in the Gulf, expect easterly waves/shortwaves to get ejected from this feature and move over portions of Southcentral. But it is too soon to tell were these shortwaves will track. All the global models have a closed low in the Gulf with numerous shortwaves embedded in them. && .AFC WATCHES/WARNINGS/ADVISORIES... PUBLIC...Flood Advisory 141.
