What forecasters said that day
The local office's own words before this winter storm 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 winter storm warning went out at Nov 11, 4:51 PM AKST, 12 hours 21 minutes earlier.
Area forecast discussion, Nov 11, 4:51 PM AKST, 12 hours 21 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 451 PM AKST Sat Nov 11 2023 .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: Tonight through Tuesday)... An upper-level low continues to drift further into the Gulf of Alaska this evening with an upper-level ridge tracking into the region behind it. The aforementioned ridge will build over the area tonight into Sunday and should bring temporary clearing to much of the area. This will result in overnight lows dropping for tonight. Areas across the Copper River Basin will see single digits, with inland areas for the remaining portions of Southcentral sitting in the teens, and coastal locations on the western portion of the Kenai Peninsula, Kodiak Island, and Prince William Sound areas ranging in the low 20s to 30s. Attention quickly turns to the next weather maker that moves into Southcentral from west-to-east Sunday evening through Monday evening. The nature of this system is different than the previous ones that brought snow to the area, and is expected to move through the region fairly quickly and not linger like the others. However, high snowfall rates are likely with this system as a lot of moisture is being brought into Southcentral. The question still remains on what exactly the winds through Turnagain Arm will do. The current thinking is that winds will increase through the arm Monday morning, but should stay out of Anchorage proper. However, if these winds do come into Anchorage proper, then blowing snow is possible across the Anchorage area. A convergence zone is likely to form as a result of these winds, and will likely bring higher amounts in west Anchorage and on the Anchorage and Eagle River Hillsides, including Hiland Road. Be sure to check back with the forecast as we continue to monitor this system and refine the details. -Sprinkles && .SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3: Tonight through Tuesday)... Unsettled conditions are forecast across the Aleutians and the Bering the next couple of days. Height rises on the backside of a Gulf of Alaska trough are contributing to an enhanced pressure gradient positioned over the Alaska Peninsula in the short term. Northerly gales with gusts to 55 knots out of bays and passes will remain possible through the evening hours from Chignik to Akhiok. A ridge of high pressure over the Bering continues eastward tonight, which will allow elevated winds over the Alaska Peninsula to come to an end by or before midnight. Further west, a Kamchatka low is pushing the next big frontal system into the Western Aleutians this evening. Ongoing southerly gales ahead of the front will transition to westerly behind the front later on Sunday. The front brings unsettled weather into Southwest Alaska beginning tomorrow. Strong warm air advection associated with the front moves inland of the Kuskokwim Coast through the morning hours on Sunday. With the warmer temperatures a transition from snow to freezing rain, to all rain is forecast. Light freezing rain will be possible for locations from Bethel to Dillingham and on into New Stuyahok. Ice accumulations of a trace to a few hundredths of an inch may be possible, but should be limited or tempered by a rather quick warm-up to above freezing. A winter weather advisory is in effect for the Lower Kuskokwim Valley. Here, freezing rain with ice accumulations of a trace up to a tenth of an inch is forecast from Aniak, southward, with light snow accumulations of 1 to 2 inches. Meanwhile, 4 to 8 inches of snow is forecast from Sleetmute to Sparrevohn and points eastward. Snow amounts in excess of 8 inches will be possible at higher elevations. The Kamchatka low brings a cold air mass back into Southwest Sunday night, with temperatures dropping to below freezing just as quickly as they warmed earlier in the day. This will see any remaining rain/freezing rain transition back to all snow. BL && .LONG TERM FORECAST (Days 4 through 7)... A very progressive weather pattern will continue into and through the extended range forecast period with multiple strong shortwaves riding over a strong but broad ridge over the Northern Pacific. Measures of predictability are good through Friday of next week and very reasonable clustering of ensemble solutions. The broad longwave ridge moves across the Southern Mainland through Thursday. A well developed shortwave trough approaches Bristol Bay for Wednesday and moves across the Gulf of Alaska through Thursday. Gale force winds and locally heavy precipitation will occur from Western Alaska and the Alaska Peninsula. Will continue to monitor the potential for high surf, coastal flooding and strong winds from Nunivak Island southward to Bristol Bay. Gales will continue around Kodiak Island and over the Southern end of the Kenai Peninsula through Wednesday. Areas of heavy snow for the Alaska Range and parts of the Kuskokwim Valley. Widespread precipitation is expected from the Eastern Kenai Peninsula across the Southcentral Coast to the Canadian border through Thursday. Expect below normal temperatures to make a return to mainland Alaska including Southcentral beginning Friday of next week. CC && .AVIATION... PANC... VFR ceilings and visibility and a prevailing light northerly wind are expected through Sunday morning. There is a chance for some shallow or patchy fog to develop overnight if skies remain mostly clear. The next system rolls in Sunday afternoon with ceilings and visibility becoming MVFR by Sunday afternoon/evening and IFR Sunday night. This next storm will bring another round of heavy snow Sunday night through Monday. During periods of heaviest snow, 12z to 18z Monday morning, snowfall rates of an inch per hour are likely. Rain or freezing rain is NOT expected with this next system. Winds will increase from the east Monday morning with a brief period of 25 mph gusts potentially producing blowing snow. CC/PP &&

SPECIAL WEATHER STATEMENT National Weather Service ANCHORAGE AK 422 AM AKST Sun Nov 12 2023 AKZ155-161-130300- Kuskokwim Delta-Bristol Bay- Including the cities of Bethel, Nunivak Island, King Salmon, Dillingham, Naknek, and Pilot Point 422 AM AKST Sun Nov 12 2023 ...FRONTAL SYSTEM TO BRING TRANSITIONS BETWEEN SNOW, RAIN, AND FREEZING RAIN TODAY... A front will begin to push inland across Southwest Alaska this morning bringing with it warmer air. Initial snow is forecast to transition to a rain/freezing rain mix as a result of the warmer air pushing atop at or sub-freezing surface temperatures. While locations from Bethel to Dillingham, and even New Stuyahok, may experience a brief period of light freezing rain in the morning, the temperature warm-up to above freezing should be fast enough to limit accumulations to a trace or a few hundredths of an inch at best. Much colder temperatures remain forecast to move back into Southwest behind the front, bringing any mixed precipitation back to snow by tonight.
