What forecasters said that day
The local office's own words before this blizzard warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Fairbanks, AK wrote its last area forecast discussion before this blizzard warning went out at Nov 20, 4:22 AM AKST, 5 minutes earlier.
Area forecast discussion, Nov 20, 4:22 AM AKST, 5 minutes before
Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 422 AM AKST Mon Nov 20 2017 .DISCUSSION... Models...For the very short term, around 24 hours, the models are in good agreement. But, beyond that they differ by up to 300 nm on location of the low that will start impacting the West Coast by Tuesday Morning, and that will significantly impact the forecast confidence starting Monday night. Will be using a blend of the GFS and Canadian models for now since they will produce stronger winds across the area, and thus more impact. The 20/00Z solutions did initialize well against the 20/06Z surface analysis. The Coastal Flood guidance has been consistent that last few runs. Aloft...at 500 hpa...A 505 dam low 400 nm north of Point Barrow will split with a 503 dam low moving northwest to the Dateline, and a 502 dam low moving southeast into Canada Tuesday. A 510 dam low south of the Western Gulf of Alaska will move south with a trough extending north to Yakutat persisting into Wednesday then moving east. Ridging from a 589 dam high in the north Pacific extends north over 175W to the Chukotsk Peninsula, then northwest, and will move to be over Nikolski to Bethel to Cape Lisburne, then northwest later this evening. The ridge continues to push east and will be south of the Alaska Peninsula and over Kodiak Island to Talkeetna to Anaktuvuk Pass to Wainwright, then northwest by Tuesday morning. By Tuesday evening it will be over the AlCan Border to Demarcation Point then northwest over the Arctic. A strong trough is developing over Kamchatka this morning and will be moving east to the Central Bering Sea by late this evening. A 502 dam low will develop just north of the Gulf of Anadyr tonight, and by Tuesday morning will be just south of Wrangel Island at 500 dam with the trough extending southwest over the Chukchi Sea Coast to the Bering Strait to Emmonak to Cold Bay. By late Tuesday evening the low will be 200 nm west of Point Lay and the trough will lie from Point Lay to Ruby to Seldovia, and by Wednesday morning the low is still about 200 nm west of Point Lay with the trough extending over Point Barrow to Arctic Village to Fairbanks to Valdez and south and moves into the Yukon Territory early Thursday. At 850 hpa...-20 isotherm lies along the crest of the Alaska Range to Paxson then to Fort Yukon to Coldfoot to Wainwright and will slowly move northeast. The -10 isotherm lies from Valdez to Healy to Huslia to Point Hope. Surface...971 mb low in the Gulf of Alaska will move south and weaken rapidly, then circle back to the north later in the week and move over the Southeast Panhandle Wednesday night. A 1030 mb high over the Arctic Plain with ridging extending southwest to a 1024 mb high over Bethel will move southeast across the Brooks Range into the Upper Yukon Flats this afternoon with ridging extending southwest to Bristol Bay. The high moves into the Yukon Territory by Tuesday morning with ridging extending northwest over the Upper Yukon Flats, and southwest over the Copper River Basin and Cook Inlet. Leeside troughing will develop north of the Brooks and Alaska Ranges and gap winds and the Tanana Valley Jet will develop as a 986 mb low currently near the Kamchatka Peninsula moves to the Gulf of Anadyr late this evening at 973 mb, and into the Central Chukchi Sea by Tuesday afternoon at 970 mb. The associated weather front will move to St Lawrence Island by this evening, and the West Coast around midnight. The leading edge of the front will lie from Wainwright to Ruby to King Salmon by Tuesday morning, and Tuesday evening it will lie from Nuiqsut to Fort Yukon to Fairbanks to Seward. The front starts breaking up as it moves further away from the low and the precipitation will slowly diminish in the Central and Eastern Interior Wednesday. Weak high pressure will build in behind the front in advance of the next system that will move in south of the Bering Strait Wednesday afternoon/evening. Arctic Coast and Brooks Range...Stratus will continue to hang around in the 2000 to 4000 foot range with good visibility and generally light winds into the afternoon. But, the approaching storm over Siberia will bring increasing winds this evening to the Northwest Coast and Western Brooks Range and near blizzard conditions to the area by Tuesday morning with winds increasing to the east. Those near Blizzard conditions move east Tuesday night and Wednesday morning into the Point Barrow area, but do not work any further east at this time, but expect some increased winds from Nuiqsut east with blowing snow. Winds speed to the west will be 30 to 40 mph gusting to 55 mph west of Nuiqsut, with winds 15 to 25 mph gusting to 40 mph from Nuiqsut east. Brooks Range passes will see increasing winds tonight with the strongest winds west of Anaktuvuk Pass gusting to 60 mph, while winds from Anaktuvuk Pass east will be gusting to around 45 mph. Snow will generally be light across the area, but the incoming storm will bring some heavy snow to the Western Brooks Range and parts of the Northwest Arctic Coast with 4 to 8 inches possible. Expect some warming of temperatures, especially on the Northwest Arctic Coast. West Coast and Western Interior...Brief period of clearing this morning has allowed temperatures to fall significantly with some areas on the coast reporting single digits. AS the area clouds up expect those temperatures to rise fairly rapidly later this morning. Snow will be moving to St Lawrence Island by early Afternoon and may mix with rain this evening, then all snow overnight. Snow will move to the coast by evening and will remain all snow, even in the lower Yukon Delta. Winds increasing this morning over St Lawrence Island and by afternoon on the West Coast. Winds increasing to 25 to 40 mph gusting to around 55 mph. Expect Blizzard conditions over a large portion of the West coast, but those conditions do not make it east of Norton and Kotzebue Sounds. Another round of Heavy Snow in the Kobuk and Noatak Valleys could produce around a foot of snow in some locations with most areas getting 4 to 9 inches. Central and Eastern Interior...Relatively quiet the next 24 hours with mainly clear to Partly Cloudy skies. Clouds will be increasing early Tuesday morning as they spread west to east across the area. Expect snow to follow Tuesday afternoon as the next weather front moves to the area. With the clear skies temperatures will again bottom out with most areas 20 to 35 below Tuesday morning. Around Fairbanks temperatures will be in the 15 to 25 below range. Temperatures warming when the clouds move in. Winds will generally be light in the valleys, but Gap winds in the Alaska Range will kick up near passes around midnight gusting to 45 mph and diminish Tuesday afternoon. The Tanana Valley Jet will also kick in late this evening with winds around Delta Junction gusting to around 40 mph from the east. && Coastal Hazard Potential Days 3 and 4...A storm will move over the southwest mainland Wednesday evening, then southwest into the Pacific. Strong north winds will develop over the Chukchi Sea, Bering Strait, and Eastern Bering Sea.
