What forecasters said that day
The local office's own words before this small craft advisory 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 small craft advisory went out at Dec 15, 4:46 PM AKST, 10 hours 21 minutes earlier.
Area forecast discussion, Dec 15, 4:46 PM AKST, 10 hours 21 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 446 PM AKST Fri Dec 15 2017 .ANALYSIS AND UPPER LEVELS... The atmosphere is becoming more dynamic again across Southcentral as a large Bering low shifts east along a very difluent upper level North Pacific jet stream which is steamrolling northeast into the Gulf of Alaska. A solid gale force (40 knots) front associated with the aforementioned upper level jet was captured moving across Kodiak into the western Gulf of Alaska at noon. This has already brought over an inch of rain to parts of Kodiak Island, and this rain will quickly spread north toward the Gulf Coast later today. Over the Bering Sea, there is a well-defined occluded low moving north across Bristol Bay toward Nunivak Island. This is bringing strong gale force winds and rain/snow to most of the Southwest coast. There is another closed low center just north of Adak Island supporting another region of gale force winds. && .MODEL DISCUSSION... The numerical models have now come into great agreement with the strong front moving toward the North Gulf Coast this evening. Over the past few days, there was quite a lot of disagreement among the models with the potential for a closed low along the coast. Some models (mostly the GFS) were very strong with the closed low scenario whereas the ECMWF and Canadian were faster and had more of a trough axis instead of a closed low...which also featured a meso low moving north through Cook Inlet. Now all models are in agreement with the latter solution, so winds are now expected to come down through Prince William Sound, down Passage Canal, and then down Turnagain Arm. Some winds will also come through Anchorage from the southeast overnight as the front passes through. In terms of precipitation, the regime is expected to become showery behind the front given the rather impressive instability, so models are not in good agreement with that and are expected to remain so for the next couple days. && .AVIATION... PANC...A front approaching the coast will bring threats for flurries and possibly a little light rain this evening and early tonight. After the front passes some southeast winds are expected to impact the terminal with the chance for a mix of rain and snow which may drop CIGS/VIS to MVFR for a brief time. After that, expect snow shower chances through the day Saturday as unstable air moves over the terminal. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... The strong front is pushing in to the Gulf of Alaska with a triple point low starting to form south of Kodiak Island. A short wave is ejecting out of the base of the low now over the Alaska Peninsula heading toward Shelikof Strait then up Cook Inlet tonight. Rain will spread from Kodiak east into Prince William Sound this evening and mix with or change to snow in the northern Sound and especially the higher elevations tonight. The short wave rapidly moving up the Inlet will complicate the forecast, particularly the wind. The Turnagain Arm and Hillside wind should be problematic. The current model solutions don't capture the magnitude of the current wind, We're also concerned about another shot of wind associated with the shortwave that is not captured well overnight into tomorrow morning. We're still anticipating the typical downslope drying across the coastal mountains as the front moves through and with the strong wind again overnight and tomorrow. Another concern is how much precipitation makes it into the Copper River Basin. At this point it looks like the downslope drying across the Chugach should prevent snow in Glennallen but expect snow along the Alaska Range and Talkeetna Mountains in the upslope flow. The Susitna Valley, once the flow becomes southerly, should see a shot of snow along the Alaska Range and north of Talkeetna, though not heavy. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)... A strong low continues to move up the Kuskokwim coast this afternoon, which is showing up nicely on the Bethel Doppler radar, with a strongly occluded front extending east through the lower Kuskokwim Delta. Strong wind gusts have been observed in advance of the front, with winds quickly dropping off following frontal passage allowing for some rain showers to develop or mix in with the snow, as warmer air surges inland in the lower levels. Meanwhile, robust cold advection in the mid-levels is quickly moving inland south of these features, with plenty of instability (relatively speaking) for some graupel or small hail to develop based on the radar and observational data across eastern Bristol Bay and adjacent locations. Additionally, numerical guidance continues to show steep mid-level lapse rates approaching 9 deg. C/km and total totals above 60. Vort maxes rotation around this the trough axis that extends from a western Bering low to the Kuskokwim low may provide enough of a burst in ascent aloft to aid in updraft strength to possible allow a stray lightning strike or two to develop. However, temporal and coverage uncertainties precluded this being adding to the coastal land or marine forecast zones. As the western Bering low heads towards the AKPEN by Sunday morning, the Kuskokwim low will rotate back southward with the pair exhibiting a Fujiwhara effect as they depart the region by Sunday afternoon. Until then, showery precipitation will continue to dominate your weather && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)... Quite an interesting setup is in place as a 971mb low north of Adak, which has been "wobbling in place" for the last 36 hours or so has started its southeastward journey. Meanwhile, a 962 mb low near Nunivak Island will halt its northward progression, and make a U-turn as it starts to be influenced more by the incoming low. These systems will rotate around each other in a unique fashion as described above, with strong cold advection continuing along their southern and western flanks. This has been quite evident in the observational data, with cloud top cooling also noted on the infra-red satellite loop. Models continue to show decent instability for this time of year, and given the instability parameters described about, an isolated thunderstorm can't be ruled out. However, graupel or small hail is a distinct possibility with any heavier shower that develops. A transitory ridge will shift from west to east across the Aleutians towards the Pribilof Islands for tomorrow, as todays systems depart the region and a low rapidly deepens to 944 mb across the western Bering by Sunday morning, with an attendant cold front stretching south. This front will impact western portions of the area with storm near storm force sustained winds developing, and seas rapidly increasing in height given a favorable fetch augmented by the baroclinic winds. && .LONG TERM FORECAST (Days 3 through 7...Mon through Fri)... The weather picture for next week is starting to become clearer. There are 2 major features to focus on. The first will be a very deep low over the Western Bering Mon and its associated front. The low will bottom out somewhere in the 945 mb range late Sun into early Mon. But its trek across the Bering will impact the whole area to start the week. Along the front, storm-force winds and moderate rain should be expected through the Aleutian chain as it pushes from west to east. Behind the front, expect widespread showers (transitioning from rain to snow) and gusty winds as cold air wraps around. As the front impacts SW AK, it will start out as snow with some gusty winds. This could create some difficult travel conditions, so stay tuned to this portion of the forecast. But with warm air and onshore flow, the snow should transition fairly quickly to rain. Today models have come into better agreement that this feature will hold together long enough to make it into the Cook Inlet region. If a few ingredients hold together, this could have the making of a decent snow event for the Anchorage area. But there is still a lot of time and variables that have to match before there is much certainty in this solution. The second major feature will be a building ridge over the North Pacific to end the week. There is still abundant uncertainty as to exactly where this feature will establish itself. On its western edge, it will bring moderate to heavy precipitation and warm and windy conditions. Underneath the ridge axis, it will likely be cold and foggy. Stay tuned to the forecast to see exactly how this pattern unfolds and what the sensible weather will be at the surface as we move towards Christmas Weekend. && .AFC WATCHES/WARNINGS/ADVISORIES...
