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.

Area forecast discussion, Apr 19, 5:05 PM AKDT, 10 hours 52 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 505 PM AKDT Fri Apr 19 2019 .ANALYSIS AND UPPER LEVELS... Broad cyclonic flow continues across mainland Alaska as a fairly persistent upper low center continues over the Southwest mainland. Cooling associated with this feature was evident on soundings across the mainland with 850 mb temperatures dropping into -10s(C) over the Southwest and -8(C) over Anchorage. At the surface, weak low pressure dominates much of the Southwest mainland to Southcentral. Unstable conditions with cold air moving in aloft brought fairly convective showers (mainly snow) to the Gulf of Alaska and coastal Southcentral. The heavy band of snow which brought accumulating snow from Western Prince William Sound to the Anchorage Bowl has narrowed and is lifting north with the upper trough. Pressure rises on the backside of the surface trough brought very gusty south winds across the Copper River Basin. Cloudy conditions with flurries or snow showers continue over much of the Southwest mainland and Bering Sea/Aleutians. && .MODEL DISCUSSION... Synoptically, models differ most on the handling of the gale low center heading north into the Gulf Saturday/Sunday. The NAM seems to the the northern and eastern most outlier of the model solutions. That said, will be leaning closer to the GFS/EC models. This will still require hand edits to grids to get desired Pop/QPF/snow amounts. && .AVIATION... PANC... Gusty southerly winds continue across the airport complex into Saturday morning before diminishing. VFR conditions will likely prevail, but passing snow showers may briefly lower ceiling/visibilities to MVFR/IFR through tonight. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... A cold upper low will exert more influence on the region as it moves north along the Western Alaska Range. Snow showers are already forming in a convectively unstable environment along the Kenai Peninsula and these will lift north and form farther east along the Gulf Coast. Some coastal areas will see some heavy bursts of snow tonight, especially favored locations like Thompson Pass. Upper ridging will begin to build Saturday as a warm front/low moves into the Gulf of Alaska. This low will bring more moisture and an increase in easterly flow to the coast with heavier snow moving into the Western PWS/E Kenai including Turnagain Pass. Strong down-inlet flow will also develop along the Southern Kenai Peninsula and will likely result in a brief period of blowing snow Sat evening/Sat night before the front moves north. Inland areas will also see a threat for snow, but the front will quickly move overhead which will likely introduce southeast winds favoring a quick cutoff to precipitation. That said, there will be a chance for a quick 1-2" snow from Anchorage to the Southern Susitna Valley Saturday evening/night. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3/Tonight through Monday)... The cold weather pattern will continue through the next few days and beyond. An upper-level low lifting northward across Southwest Alaska tonight will produce snow showers, mainly over interior Bristol Bay from about King Salmon north and east. Otherwise, expect continued mostly cloudy skies with isolated showers. A storm tracking into the Gulf on Saturday now appears likely to initially take a much farther east track than previous forecasts indicated. Thus, it now looks like Southwest Alaska will not see any impacts from this system until late Saturday night or Sunday morning. At that point in time the low will track into Cook Inlet, with moisture spreading westward across the Aleutian and Alaska Ranges. A deformation band will set up in the corridor from Iliamna to Sleetmute, with at least a few inches of snow likely along or near this axis. Further west along the Southwest coast, another round of cold air will lead to gusty winds and snow showers. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3/Tonight through Monday)... Expect very little change in weather over the Bering Sea and Aleutians as a blocking ridge remains anchored over the western Bering and a trough over the eastern Bering. A series of upper-level short-waves will focus shower activity and also help drive another round of Arctic air southward Saturday night through Monday. If anything, expect an increase in shower activity as we head through the weekend. With such cold air aloft, precipitation will be primarily in the form of snow, though there could be a mix of rain and snow at times along the Aleutian chain. && .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 among 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 for the most locations on the southern mainland will be that showers clear out. By the end of the week, there is high model disagreement. Ensembles are preferred at this time. && .AFC WATCHES/WARNINGS/ADVISORIES... PUBLIC...NONE. MARINE...
