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 Fairbanks, AK wrote its last area forecast discussion before this gale warning went out at Nov 30, 1:37 PM AKST, 13 hours 32 minutes earlier.
Area forecast discussion, Nov 30, 1:37 PM AKST, 13 hours 32 minutes before
Northern Alaska Forecast Discussion National Weather Service Fairbanks AK 137 PM AKST Thu Nov 30 2017 .DISCUSSION... Models...Run to run continuity looks good in the short term. There seems to be a bit better agreement in the midrange, though the feature heights and pressures from the GFS are a bit stronger than the other solutions. The 30/12Z solutions lined up well with the 30/18Z surface analysis. With good continuity it seems like an equal blend in the way to go today at least in the short term. Will need to tweak the temperatures on an individual basis. Extended guidance from WPC, which used primarily a blend of the Ensemble means, will be favored. Aloft...at 500 hpa...Ridging extends southeast over the Central Arctic Coast from a 541 dam high near 81N 160E and will rotate west with the axis moving over Wainwright by Friday afternoon, and over the Chukchi Sea by Friday morning. As that is happening a 509 dam low near the Bering Strait will move just south of Wrangel Island, then gets absorbed into a 486 dam low in the Bering Sea. Ridging south of the Bering Strait will continue to move east squeezing out a col over the Central and Eastern Interior, with the axis moving to lie from King Salmon to Cape Lisburne by Friday morning, and from Cordova to Point Lay by Saturday morning. The low in the Bering Sea will slide east a bit as an associated wave pushes east over the Eastern Bering Sea by Friday morning, and to the Bering Strait by Friday afternoon. The wave will push inland a bit as it moves north up the coast and merges with troughing over the Chukchi Sea and Arctic Coast. A 506 dam low over Banks Island will drift southwest to MacKenzie Bay by Friday morning with troughing extending west over the Eastern Arctic Coast. At 850 hpa...Temperatures over the forecast area will remain fairly static from -5C to -15C as the -10 isotherm moves to lie from Dawson YT to Point Lay by Friday evening as some warm air in advance of the next system pushes north over the Lower Yukon Delta. Surface...Ridging continues over the Arctic extending south over the Central Arctic Coast from a 1034 mb high north of the New Siberian Islands. Weak high pressure remains over the Central and Eastern Interior and continues to weaken. A vertically stacked low that was over Cold Bay yesterday has move to south of the Gulf of Alaska at 990 mb and will continue to move east and southeast. A trough of low pressure over the Western Interior will merge overnight with low pressure around a 963 mb low in the Western Bering Sea that will be pushing into the Eastern Bering Sea tonight. A weather front associated with the low in the Bering Sea will move to St Lawrence Island by midnight and to the West Coast by Friday morning. Lee side troughing redevelops Friday and high pressure over the Copper River Basin strengthens so expect the pressure gradient to tighten up across the Alaska Range Friday night with strong gap winds developing in the Alaska Range. Arctic Coast and Brooks Range...Stratus, flurries, areas of fog, mainly northeast winds. No significant snow expected. Strongest winds will be over the Northwest Arctic Coast as they increase as the weather front moves into the area Friday afternoon and southeast winds increase to 20 to 30 mph gusting to 45 mph. West Coast and Western Interior...Blizzard developing on St Lawrence Island tonight and Warning has been issued. As the front move to the coast Advisories are in effect for coastal areas south of the Bering Strait. Will be issuing Winter Weather Advisories for zones 207, 208, 209, and 210 as near Blizzard conditions develop. Strongest winds will be on St Lawrence Island and the Bering Strait Coast with gusts around 50 mph. Inland conditions not as poor as winds will not be as strong. Expect some areas of Blowing Snow reducing visibiltiy, and some heavier snow around Kaltag and the Nulato Hills where around 7 inches of snow may fall. Central and Eastern Interior...Weak high pressure over the area will continue to weaken as the low approaches from the west. Leeside troughing developing and gap winds will increase Friday through the Alaska Range and continue into late Saturday. Gap winds in the Eastern Brooks Range will pick up Saturday afternoon and diminish Sunday. Weak trough over the Upper Yukon Flats will slide south tonight spreading clouds to the Alaska Range and a chance of light snow or flurries to the Middle Tanana Valley and Fortymile Country. Temperatures will continue to slowly warm through Saturday. && Coastal Hazard Potential Days 3 and 4...None. && Extended Forecast days 4 to 7...960ish mb low moves out of the North Pacific to Bristol Bay early Monday setting up a strong Chinook event over the Alaska Range. Expect much warmer temperatures in the Alaska Range, and areas north of the Range. Highs Monday and Tuesday at Denali NP could reach 40, and many locations around the Middle Tanana Valley could see highs in the 20s to near 30. Temperatures will cool after Tuesday. Winds with the Chinook may be gusting to 70 mph in some Alaska Range locations. && .AFG WATCHES/WARNINGS/ADVISORIES... Blizzard Warning for AKZ213.
