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 Nov 25, 5:50 AM AKST, 8 hours 58 minutes earlier.
Area forecast discussion, Nov 25, 5:50 AM AKST, 8 hours 58 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 550 AM AKST Wed Nov 25 2020 .ANALYSIS AND UPPER LEVELS... A high amplitude ridge exists over the central Alaska mainland with a negatively tilted trough over the Bering Sea. A large front is present on the leading edge of the trough extending from the Kenai Peninsula to Kotzebue Sound. Aloft, a 80 kt jet core exists over the front. On the backside of the front, cold air advection and westerly winds can be seen on satellite in the form of closed cell cumulus clouds and scattered snow showers. Near the surface radar indicates the front continuing to progress across Southwest. Surface observations along the west coast indicate precipitation has transitioned back to snow as westerly cold air advection begins to take hold of the region. Over the interior, rain, warm temperatures, and lee side warming west of the Alaska Range continues. Both the Middleton Island and Kenai Radars are beginning to fill in as the front moves into the Southcentral. Down inlet flow can be seen at Kenai with northerly winds as the lee side trough develops in the western Gulf. Winds are also increasing in Portage as the front moves over the north Gulf coast. && .MODEL DISCUSSION... Model agreement in the short term remains good. Models have held true to their own solutions in regards to the low moving up the Cook Inlet on Wednesday. Model agreement continues to be poor past 36 hours. The main feature that the models are struggling with is a surge of cold air moving across the north Pacific this morning which can be seen on satellite as a developing baroclinic leaf near 175W. The models all develop 3 upper level and surface lows that are expected to move into the Gulf on Friday. The latest model runs show a large spread in the location of these features which result in a lower forecast confidence for precipitation over Southcentral. Over the western Bering there is some model discrepancy over the timing of two strong lows merging into one on Friday, however the wind field is similar between the models so forecast confidence for this system is high. && .AVIATION... PANC...A front has moved over the terminal this morning producing southeasterly winds and low-level wind shear. Precipitation is expected to remain away from the airport through the afternoon when the Turnagain Arm wind may briefly enter the terminal bringing a rain and snow mix. The arrival of the Turnagain Wind around 23z will bring an end to any wind shear. The onset of precipitation will bring down ceilings to MVFR. Snow is likely after sunset, which should lower visibility to IFR conditions through the overnight hours. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2...Wed and Thanksgiving)...A storm system developing near Kodiak Island is right on track to bring active weather across Southcentral through the day today. Winds have already started to increase across many of the marine areas and will continue to due so, especially from Prince William Sound over to Passage Canal. There were no significant changes to the thinking from the previous forecast, so overall changes were minimal into early Thanksgiving. The low will track up Cook Inlet later today. High winds are still expected along Turnagain and the higher elevations of the Anchorage Hillside. There will also be strong winds through Portage Valley. These winds will generally be across the terrain. This will cause localized warming thanks to some downsloping. Temperatures will generally push into the mid 30s. Precipitation is set to push from Kenai late this morning to the Anchorage Bowl late this afternoon. Due to those locally warmer temperatures, the onset is likely to be a mix of rain and snow or potentially just all rain. However, it will not be very much precipitation during that warm period. As the upper level energy arrives from the west, it will be coincidental with much colder air. This should allow for a couple inches of snow accumulation from Anchorage up to the Matanuska Valley, with the highest amounts favoring west-facing terrain. As the front lifts through late this evening, winds will rapidly diminish across all areas. But the active pattern is not over yet. Forecast confidence is increasing in the potential for another, weaker low to more along the northern Gulf coast Thu afternoon into Fri. There is still a fair amount of model uncertainty with this system, but one thing is quite certain, it will be much colder. This should allow for the precipitation type to remain safely all snow across the area. This is a much more compact system, so pinpointing the exact location of best QPF will take some more time to refine. That said, we will be keeping a close eye on it as it has the potential to produce several more inches of snow across many of the population centers heading into the Holiday Weekend. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)... A frontal system moving through Southwest Alaska this morning will continue moving from southwest to northeast. This front is bringing mostly rain to many areas due to a decent amount of warm air with this system. Rain has changed back to light snow across the westernmost portions of the YK-Delta this morning with temperatures dropping back down to around freezing as the cold air moves back in. The cold air will continue moving across Southwest today in a southwest to northeast direction with areas across the northern portions of the Middle Kuskokwim Valley seeing the cold air return last. Windy conditions are also moving through Southwest in association with the front with Iliamna reporting a gust upwards of 66 mph in the last hour. Winds will remain the strongest through northern Bristol Bay and into the Middle Kuskokwim Valley through later this morning before gradually diminishing in the afternoon. Quieter conditions are expected across Southwest for later this evening into Thursday, though snow showers are expected especially across the coastal regions of Bristol Bay and the YK- Delta. There is the possibility of some these snow showers making it far inland with even areas like Bethel, Sleetmute, and Sparrevohn possibly getting in on the action. One thing that is being watched is a system moving northward near Kodiak Island that may send a band of snow into the Iliamna area for Thursday afternoon. However, this part of the forecast remains uncertain at this time even with it being 24 hours out. Right now, thinking that if this band forms it will stay over the mountains or on the other side closer to Kodiak Island north through Cook Inlet. Attention then turns to the next frontal system moving northward along the AKPEN that may bring a round of snow to the coastal villages across Southwest. Timing appears to be Friday afternoon into Saturday. This system has the potential to bring a couple inches of snow to places such as King Salmon and Dillingham over to Cape Newenham. Some parts of the Kuskokwim Delta Coast may also see some snow out of this but think at this point most of the accumulating snow stays on the east side of the Kuskokwim Mountains. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)... Westerly flow continues this morning across the Bering Sea. This is expected to continue through Thursday morning when the next system begins to move into the area. From now till then expect small craft winds across much of the Bering with some low end gales across the westernmost portions of the Aleutian Chain and the Bering. Widespread snow showers will also accompany the gusty winds as cold air continues to flow across the relatively warm water surface. This can be seen this morning on the nighttime microphysics imagery in the form of cumulus clouds which have a popcorn look to them. The next system begins to move into the western Bering Sea and western Aleutian Chain beginning late Thursday morning/early afternoon. This system is expected to bring more unsettled weather with periods of rain and high winds and seas to the area. Storm force winds are expected in the marine waters to the south and north of the central Aleutian Chain beginning Thursday afternoon and continuing through Friday evening. Some model guidance is showing the risk for hurricane force winds in the marine zone north of Adak Thursday evening into Friday morning. Therefore, this was placed into the forecast for that zone. However, the risk is there that the hurricane force winds could be more widespread. This will be fine tuned more today and sent with the afternoon package. A High Wind Watch has been issued for Adak and Atka in the central Aleutians for Thursday evening to Friday morning for wind gusts upwards of 85 mph. Wave heights will also come up in response to the winds with 30-40 ft seas expected north and south of the central Aleutian Chain. && .MARINE (Days 3 through 5: Friday through Sunday)... Gulf of Alaska: Fair confidence with overall pattern but much uncertainty remains in the details during the 3-5 day timeframe. Friday a Gale force low will move across the southern Gulf. The low will weaken and move into the eastern Gulf Friday afternoon. however low confidence on track and strength. Friday afternoon a gale force front moves into the Gulf there is a chance of near storm force winds southeast of Cordova with the barrier jet, but low confidence on strength and higher confidence with track. This front will move inland and weaken by Saturday afternoon. A gale force low will move in behind the front by Saturday afternoon. This low weakens as it moves into the northern Gulf Sunday morning, fair confidence on track and intensity. Bering Sea: A storm force low moves just north of the Aleutians across the southern Bering on Friday and Saturday. Most of the storm force winds are expected on Pacific side of Aleutians. This low will move east into the Gulf Saturday evening. Good confidence on track, but lower confidence on strength of low. Saturday night through Sunday another storm force low is expected track south of the Aleutians, low confidence with track and strength of this low. && .LONG TERM FORECAST (Days 4 through 7...Saturday through Tuesday)... Progressive flow will continue to dominate the long term with a series of fronts and lows moving across the Aleutians and Bering into Southwest and Southcentral Alaska. These systems may bring chances of accumulating snow to Southwest and Southcentral. Models are hinting at a slight pattern shift as the storm track and upper level jet may move south keeping the storms south of much of the Aleutians and Bering, with the exception of the Gulf which may be influenced by a strong North American ridge which will direct storms into the Gulf and possibly into Southcentral by the middle of next week. Good confidence on the overall pattern, but lower confidence on details of track and strength of systems. Saturday morning an occluded front will move into Southwest Alaska with rain near coast and snow farther inland. This front will stretch across the AKPEN to near Kodiak Island and across the Gulf bringing heavier precipitation to Kodiak Island and northward across the Kenai and Prince William Sound. As the front moves north models are starting to show a triple point forming near Kodiak Island and tracking north, however the track and strength of this low is very uncertain. Rain or snow is possible across Southcentral late Saturday into Sunday as the front moves inland, but details uncertain especially with precipitation type. This front will also produce Gale force winds across Gulf and strong winds, especially near the coast and the usual local effect winds. The parent low to this front will move south of the eastern Aleutians and AKPEN Saturday. This low will produce storm force winds mainly on the Pacific side of the Aleutians and weaken to Gales as it moves into the Gulf by Saturday evening. This low then moves into northern Gulf late Sunday and weakens. Fair confidence with this system, however lower confidence with the details of local winds and precipitation type. Yet another storm force low tracks just south of the Aleutians Sunday and Monday still a bit of spread among the models, but relatively good agreement considering its 5 days out. Depending on the track of low and front Southwest Alaska may get some snow out of this system as the EC and GFS show the possibility of snow in the deformation zone, but too much uncertainty to say this will happen at this point. The front associated with this low will track into the Gulf on Monday bringing another round of winds, rain, and snow. Tuesday the front will move inland and weaken, while much of the Bering and Aleutians will be under quieter weather as northerly flow sets up as models hint at the upper jet dipping farther south keeping the storm track south of the area. && .AFC WATCHES/WARNINGS/ADVISORIES...
