What forecasters said that day
The local office's own words before this 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 storm warning went out at Apr 20, 4:50 AM AKDT, 10 hours 40 minutes earlier.
Area forecast discussion, Apr 20, 4:50 AM AKDT, 10 hours 40 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 450 AM AKDT Sat Apr 20 2019 .ANALYSIS AND UPPER LEVELS... A deep trough continues to remains entrenched along an axis that extends from northwestern Alaska to the Alaska Peninsula. This trough is anchored by a pair of mid-level lows, with one centered near Kotzebue, and the other across southwest Alaska. These two features, along with several smaller scale circulations, have been rotating around each other in a Fujiwhara-like fashion, which helps maintain the trough orientation and position. At the surface, some small scale circulations have been observed on Doppler Radar imagery this morning, with one being located south to southeast of Bethel (this was interesting to watch around 09z when the tiny MCV induced a larger mass response in the wind fields), and another that was observed over the Cook Inlet west of Kenai, which has since dissolved. A general showery type pattern is seen in radar imagery across southwest Alaska, with a greater coverage and intensity noted across much of Southcentral, especially near the Prince William Sound Coast. This heavier precipitation has played a role in reduced visibilities at some area airports. && .MODEL DISCUSSION... The models remain in excellent agreement at the surface and aloft, leading to a higher than average forecast. The GFS model is slightly faster and has a little further west position of a surface low moving towards the Kenai Peninsula on Sunday. However, both models are within a millibar or two in strength of each other, with good pressure field continuity. Thus, impacts to the forecast are minimal. && .AVIATION... PANC...Snow showers crossing the terminal will hold ceilings down to around 2200 feet for a few more hours, before VFR conditions prevail through the afternoon. However, an area of low pressure will approach the region later this evening and into Sunday, dropping both ceilings and visibilities back into the MVFR range, as widespread precipitation develops. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2...Sat and Sun)... A dynamic pattern will unfold through the weekend. The upper level low that brought the colder air and snow to close out the work week remains over the Susitna Valley this morning. Its trailing shortwave and associated instability continue to produce widespread showers across much of Southcentral. With the cooler airmass, most locations are holding as snow during the overnight hours except for spots right along the immediate coast. This shortwave should continue to lift north and out of the area through the day today. A transient ridge will slide through this afternoon and could even bring some breaks of sunshine back to the area. The April sun should once again allow high temperatures to crest into the low 40s for nearly all areas. Another potent low will take shape over the Gulf of AK heading through the day. In advance of this system, deep southerly flow and instability along the coast (mainly Prince William Sound through Cordova) will keep precipitation falling through the day. Higher elevations such as Thompson Pass could pick up several more inches of snow. As the low center itself approaches tonight, it will shift the corridor of heaviest precipitation slightly to the west highlighting Western Prince William Sound through Seward. It will bring several more inches of snow to the higher elevations (1500' and above) around Turnagain Pass. This system will also create some gusty south to southeast winds with a fairly tight pressure gradient. These will stretch up through the typical locations of the Turnagain Arm, Knik River Valley, and Copper River Basin. For places along the Western Kenai Peninsula, there could be a brief period of blowing snow early Sun morning as down-Inlet flow initially reinforces some colder air. But once the east- southeast winds push in Sunday, temperatures should rise quickly and precipitation at sea level will quickly turn over to rain. Around the Anchorage Bowl, a brief shot of snow is all that is expected before cross-barrier flow ramps up and dries things out. Unsettled weather will remain in the forecast to start next week. While there doesn't appear to be any large-scale snow events for the population centers at this time, the airmass will certainly be cold enough to support snow and keep things feeling like early March. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3/Today through Monday night)... An upper level low will continue to track northward over western Alaska today. As it phases with a second upper low to the north, a broad upper trough will form and continue to bring cooler temperatures, mostly cloudy skies and scattered flurries over Southwest and mixed precipitation over the AKPEN. Although some uncertainty still exists, models are coming into a general consensus for widespread accumulating snow in the Lower Kuskokwim Valley on Sunday as a strengthening low tracks northward over the Gulf. The center of the low will move over Cook Inlet by midday providing a good setup for the development of a deformation band as the associated moisture tracks over the Alaska Range. While higher elevations will as usual see the most accumulation, confidence is moderate to high for at least 2 to 5 inches from Iliamna to Crooked Creek with localized higher amounts possible by Monday morning. Areas along the Kuskokwim Delta and Bristol Bay coast should remain generally snow free, however onshore flurries and gusty winds are likely along the immediate coastline. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3/Tonight through Monday night)... A broad upper level low and associated shortwave troughs will continue the cool and cloudy pattern experienced over the region the past several days. Persistent northerly flow will bring scattered snow showers (possibly mixing in the afternoon) for much of the Aleutians today. These will become more widespread Sunday and Monday. Again, mixing will be possible when maximum temperatures will occur, however precipitation should still mainly fall as snow. && .MARINE (Days 3 through 5)... A series of weak lows will move through the region early next week. Models are in good agreement that these lows will stay below gale force, however there is a chance for a few isolated areas that could briefly reach gale force winds in the Gulf. && .LONG TERM FORECAST (Days 3 through 7)... The long term forecast, beginning Monday night, looks to have a broad, complex low over the southern mainland. This setup will keep the region unstable with showers over the area. There is some inconsistency amongst the models on when the pattern will shift but the general idea is that the low will push off to the southeast sometime Wednesday with high pressure moving in. The result is the showers clearing out for most locations for the southern mainland. By the end of the week there is high model disagreement resulting in the ensembles being preferred. && .AFC WATCHES/WARNINGS/ADVISORIES... PUBLIC...NONE.
