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 Aug 12, 4:41 PM AKDT, 10 hours 19 minutes earlier.
Area forecast discussion, Aug 12, 4:41 PM AKDT, 10 hours 19 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 441 PM AKDT Mon Aug 12 2019 .ANALYSIS AND UPPER LEVELS... A strong upper level ridge remains over Southcentral Alaska today with Southwest mainland Alaska under southwest flow aloft on the other side of the ridge axis. This pattern is bringing in the areas of rain to Southwest mainland Alaska with just high clouds moving over the ridge in Southcentral. This ridge is strong enough to suppress convection across Southcentral Alaska. At the surface the ridge is over the Gulf of Alaska and stretching to the south of the Alaska Peninsula. The main low in Eastern Russia has a front stretching across the Bering Strait and then southward over the Bering Sea. A wave along this front can be prominently seen on IR satellite near Adak. && .MODEL DISCUSSION... Models remain in good agreement through the middle of the week and not much needs to be mentioned for that time period. What is quite notable is for the end of the week where there has been a good amount of uncertainty in the models. Overall we have been leaning toward the ECMWF solution which maintains the strong ridge over the mainland part of the state over the GFS solution which shows a strong trough digging southward near the Alcan border on Friday and Saturday. Part of the reasoning has been the stability of the ECMWF and the way the GFS has tied to break down the ridges too fast this summer. With all that said, the 12Z ECMWF run did a major jump toward the GFS solution and shows a 500 mb low over Northwest Alaska Thursday night sweeping to the northeast Gulf of Alaska by Friday night. This would drop upper level temperatures significantly and surface temperatures will follow. This is the first run of late where the models are showing similar solutions and more runs will be needed to confirm this forecast shift. && .AVIATION... PANC...VFR conditions will persist. Winds are expected increase as they shift to the south-southeast late this evening and persist through tomorrow. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)... (Tonight through Thursday evening) The main forecast challenges were afternoon high temperatures and our potential for some much needed rainfall. Speaking of those temperatures, Ted Stevens International Airport has climbed to 77 degrees this afternoon, tying the record from 2005. We may climb another degree or two before leveling off and beginning our descent. These warm temperatures look to continue, as the models have decreased the 700 mb RH for the next few days, especially for Tuesday night and wednesday. This will allow for more breaks in the cloud cover to develop, boosting afternoon highs. Thursday is where we may have to really boost them some more, as 850 mb temps are progged to be 12 deg. C, which is a degree C above today, when we hit 77. At that time, projected RH fields indicate scattered cloud cover at best. Overnight lows look to remain relatively unchanged, compared to what has been observed the last few days. As for the precipitation, a series of disturbances will pass by to our north over the next 48 hours. The first of which will send a weak front southward, reaching the north central portions of the Matanuska Valley and Copper Basin, before frontolysis commences (the weakening/dissolving of a front). This combined with southwest winds just above the surface should provide enough surface convergence for some showers to develop, reaching as far south as a Kenai to coastal Gulf line for Tuesday into Wednesday. These rainfall chances fall by the wayside for Thursday, with dry weather expected for most locations, with the exception being near the Alaska Range. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3/Monday evening through Thursday)... A frontal system continues its slow push across Southwest Alaska. It will continue to move slowly and drag warm, moist air behind it. So expect it to bring rain, cloud cover, and cooler temperatures to the area for the next couple days. Closely following this system is another low that will skirt the southwest coast Wednesday into Thursday. This low will take a more northerly track so it will only provide a chance of precipitation for all except the Yukon Delta. The more northerly track will also provide a chance for interior areas of southwest AK to warm and dry some. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3/Monday evening through Thursday)... A frontal system is entering the central Bering Sea from the south, just as the frontal system in the eastern Bering Sea moves over Southwest AK. This quick succession of systems that are tied together means continued southerly winds, low level clouds, fog, and rain for the Bering Sea and Aleutians. Tuesday night into Wednesday a strong system enters the Bering, again from the south. Gale force winds will also accompany this system as well as more rain. This system takes a more northerly track and enters through the western Aleutians, so the western and central Bering will see most of the action later in the week. && .MARINE (Days 3 through 5)... With upper-level ridging remaining over the Gulf through midweek, expect west-southwesterly winds in the 20 to 25 knot range for Shelikof Strait, southern Cook Inlet and across the Barren Islands. Offshore flow then increases Thursday and lingers into Saturday with areas of northwesterly gales likely across the Barren Islands, out of terrain gaps, and in other favored offshore flow locations. For the Bering and Aleutians, a ridge building across the eastern Aleutians and Bering will produce gusty offshore winds across the channeled bays of the southern AKPEN Thursday evening through Saturday. Low pressure south of Shemya will produce southeasterly gales along a stalled front draped across the western and central Aleutians Thursday and Friday. Winds will weaken late Friday into Saturday but remain at small-craft advisory levels. && .LONG TERM FORECAST (Days 3 through 7)... By Thursday evening, a broad upper-level ridge stretching from the eastern Aleutians to the Alaska Panhandle begins to weaken with the axis shifting to the south and west. This is in response to a vigorous upper-level shortwave dropping southeast from the Chukchi Sea toward the Yukon. This shortwave elongates as it moves into the Yukon on Saturday, introducing a northerly cyclonic flow across the state as the ridge retreats over the Bering. At the surface, the upper-level dynamics will result in the movement of a frontal system across the state with the redevelopment of a surface low over the eastern Gulf sometime late Friday or Saturday. The bulk of the moisture with this system will remain north of Southcentral due to upslope flow along the Alaska Range; however, areas of light rain showers remain possible over the mountains and within the Copper River Basin through late Friday as the system passes. Another area of focus will be the likely development of stronger offshore winds through the favored channeled areas across coastal Southcentral in response to the development of low pressure in the Gulf. There is still quite a bit of uncertainty with timing and intensity with this feature (see aforementioned model discussion), but these winds are expected to increase late Friday and linger through the weekend. Finally, temperatures are also expected trend cooler, becoming more seasonal through the weekend, as the northerly flow advects in colder air, dropping temperatures aloft by around 5C. Farther west, the retreating ridge will keep conditions rather quiet and slightly cooler over Southwest Alaska and the eastern half of the Bering through the weekend as a stalled frontal boundary allows southerly winds and precipitation to persist across the central and western Aleutians. && .AFC WATCHES/WARNINGS/ADVISORIES...
