What forecasters said that day
The local office's own words before this high wind 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 high wind warning went out at Dec 20, 6:50 AM AKST, 4 hours 25 minutes earlier.
Area forecast discussion, Dec 20, 6:50 AM AKST, 4 hours 25 minutes before
Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 650 AM AKST Sun Dec 20 2020 .SYNOPSIS... A drastic pattern change will begin Monday across Northern Alaska as a large low moves into the Bering, bringing a potentially significant winter storm to the West Coast and Western Interior. This storm will also aid in the development of strong southerly gap winds through Alaska Range Passes and strong winds along the Tanana River. Warmer temperatures will surge north, initially across the Southern Interior Monday night then north to the Arctic Coast by Wednesday. In the meantime, light snow is falling across the Central Interior, from Tanana east to Fairbanks, as a low moves into Alaska near Prince William Sound with an occluded front draped across the Interior. Snow chances will diminish and push east through today as the low weakens and moves into Canada. Cold temperatures, coupled with gusty winds over Northwest Alaska, are creating very cold wind chills this morning and will improve today as winds decrease over the Interior. && .DISCUSSION... At the surface, a weak low moving into Prince William Sound will spread light snow into the Central Interior and then into the Eastern Interior this afternoon as the low and associated occluded front tracks east. A weak trough in the Bering Sea will continue to produce light snow from the Bering Strait south across St. Lawrence Island into this evening. High pressure over the high Arctic is relinquishing its grip on the weather for Northern Alaska today. Attention then shifts to a strong low, sub 960 mb, moving into the Bering Sea Monday. This storm will feed ample moisture into the West Coast and Western Interior, as front rotates around the low into the YK Delta and then moves north up the coast, potentially bringing significant snowfall Monday night into Tuesday. Snow moving north coupled with strengthening winds for St. Lawrence Island and the YK Delta, may produce blizzard conditions by Monday evening. In addition, a strong gradient will develop over the Alaska Range, increasing southerly gap winds through passes and creating a Tanana Valley Jet. This system will also be responsible for bringing a surge of much warmer temperatures into Northern Alaska, initially across the Southern Interior Monday night then north to the Arctic Coast by Wednesday. Models converge on a solution that shows a strong low moving into the Bering Sea by Monday morning, but diverge on the strength of the main low. So, with this morning's forecast package, we leaned on the GFS as it reflects a deeper low. Aloft, at 500 mb, models initialize well with a trough over much of Northern Alaska. A shortwave will move through the Central and Eastern Interior today, weakening this afternoon as it moves into Canada. A ridge will build into Western Alaska Monday morning ahead of a deep 480 dam (decameter) low moving into the Southern Bering and will remain quasi-stationary over the Bering through Tuesday. The ridge builds north and east over Eastern Alaska and the Yukon on Tuesday. This will bring strong southerly winds aloft across the Alaska Range, aiding in the development of strong gap winds, and brings much warmer temperatures to most of Northern Alaska by Wednesday. North Slope and Brooks Range... A weak trough draped over the North Slope will remain through Tuesday, keeping low ceilings and the potential for flurries along the Beaufort Sea Coast. Winds will ease today, easing the affects of any blowing and drifting snow, along with the cold wind chills. Cold temperatures have settled in, especially along the Arctic Plain, this morning. Wind increase slightly Monday, with cold temperatures in place, wind chill values plummet Monday into Monday night. Then, temperatures will moderate drastically Tuesday as much warmer temperatures pushes into the region as southerly flow develops over the region due to a ridge building over the Interior. West Coast and Western Interior... Winds easing today, with the strongest winds hanging on just offshore near Point Hope. Otherwise, relatively benign weather conditions over much of the region as ridging builds in ahead of a large storm moving into the Bering Sea Monday morning. A weak trough will linger over the Bering Strait south to St. Lawrence Island today, continuing to bring blowing snow and snow to St. Lawrence, and diminishing tonight. Attention then shifts to Monday through Tuesday, where a strong low will move into the Bering Sea. This low will bring the potential for a significant winter storm to much of the West Coast and Western Interior, with heavy snow, strong winds, freezing rain for the Southern Western Interior, and blizzard conditions for St. Lawrence Island and the YK Delta late Monday into Tuesday. Strong wind with snow and blowing snow, creating blizzard conditions, will spread north along the West Coast Monday night into Tuesday, bringing low visibilities. Expect 4 inches of snow for most areas south of the Bering Strait with up to 7 inches on the east side of the Nulato Hills. At this time, winds are expected to remain offshore, which will limit any coastal flooding concerns. Central and Eastern Interior... Radar returns this morning show light snow falling over the Fairbanks Area, this will gradually diminish through this afternoon with the associated front weakening and moving east. Snow accumulations of around one inch expected through tonight. Otherwise, temperatures will remain steady this morning with the increased cloud cover and light snow across the area. Winds will decrease through the day, easing the affects of cold wind chills. Temperatures will fall again Sunday night as a quick shot of arctic air moves through before a big changes occur Monday, as an upper level ridge moves over the region bringing a significant warm up on Tuesday. Very strong south gap winds are expected to develop in Alaska Range Passes Monday night and continue into Tuesday as a strong Chinook moves into the area, keeping the Fairbanks free of any precipitation. Strong inversions will likely develop over the interior on Monday and Tuesday as temperatures warm dramatically over the hills, but will be slower to warm in Valleys where arctic air will remains trapped. Coastal Hazard Potential for Days 3 and 4... No concerns at this time. Extended Forecast for Days 4 to 7... Beginning the extended period on Wednesday, model concensus shows an upper level trough parked over the Bering Sea with an associated large low at the surface, keeping conditions unstable over the West Coast and Western Interior. This complex will remain quasi-stationary through Friday and move north as another large low moves into the Southern Bering on Saturday. Lows will develop and ride up the east side of the trough into Prince William Sound on Wednesday through Friday, spreading moisture north into the Central and Eastern Interior. && .AFG WATCHES/WARNINGS/ADVISORIES...
