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 Mar 8, 4:11 PM AKDT, 11 hours 57 minutes earlier.
Area forecast discussion, Mar 8, 4:11 PM AKDT, 11 hours 57 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 411 PM AKDT Sun Mar 8 2020 .ANALYSIS AND UPPER LEVELS... In the upper levels, a high amplitude blocking ridge is sitting to the south over the north central Pacific Ocean. A series of low amplitude (weak) short-wave troughs are tracking from west to east across the Alaska Region in fairly zonal flow. The strongest of these waves is tracking into Southcentral today, with widespread snow for all areas except the Copper River Basin. A weak triple point low at the surface is also transiting the northern Gulf. This morning, as it passes south of Anchorage, it did produce some downslope flow in Anchorage and the Matanuska Valley. However, as the low continued eastward the downslope flow ended and shifted to broad south to southwest flow, which is enhancing snow rates in upslope areas of the Chugach and Talkeetna Mountains. There is also a low level deformation band (of heavier snow) on the back side of the low, which has been tracking slowly eastward from Cook Inlet to the mountain through the day. The heaviest snow totals have been in the Susitna Valley, where a foot more of snow has been reported over the past couple days. Snow is tapering off across Southwest Alaska as the short-wave exits eastward, with snow lingering along the west side of the Alaska and Aleutian Ranges in westerly upslope flow. As weak short-waves drop down from the Arctic, cold air advection has ensued in the Kuskokwim Valley and Kuskokwim Delta. Out over the Bering Sea, a broad trough is tracking eastward across the heart of the southern Bering Sea, with a weak surface low near the Pribilof Islands. Precipitation with the trough is mostly showery, while with the surface low there is an area of steady light rain and snow across the eastern Bering Sea and Pribilof Islands. Winds are generally small craft advisory or lower across the region, though Arctic air filtering southward behind the trough, leading to strengthening winds from the central Bering to central Aleutians. && .MODEL DISCUSSION... Model guidance is in excellent agreement with large scale features over the next few days and forecast confidence is above average. && .AVIATION... PANC...The heaviest of the snow will shift east of the terminal by evening, so generally expect improving ceilings and visibility. However, broad cyclonic flow will persist in the upper levels, with weak waves dropping down from the northwest. Thus, periods of light snow will likely persist through at least Monday morning (possibly beyond). It will be challenging to identify the best time periods of snow due to the weak forcing mechanisms. Generally expect MVFR conditions to prevail, with low end VFR possible when it is not snowing. VFR conditions should then settle in during the day Monday as low level northwesterly flow increases and drier air begins to advect into the area. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... An upper trough continues to shift eastward from northwest AK, and a leading shortwave is tracking through Southcentral. A surface low in the Gulf associated with the shortwave continues to wrap moist southeast flow into Southcentral, overrunning cold air at the surface farther inland. This will maintain light stratiform snow over the Anchorage Bowl/Mat-Su Valleys/Kenai Peninsula tonight. Snow will slowly taper off to flurries Monday, with a few exceptions. Weak cold air advection/upslope flow over the Anchorage Hillside and Palmer area could maintain light snow through Monday night. In the Susitna Valley, especially from Willow north, steady south flow aloft and a surface trough will maintain snow a bit longer than elsewhere, possibly into Monday night as well. These features will exit to the east Monday, and the parent upper trough will dive southeastward towards Southcentral AK Tuesday. Light snow will spread into the Copper River Basin, as south flow aloft ahead of the trough increases moisture advection. Expect a few inches of snow along the Richardson Hwy Monday night. Otherwise, weather Tuesday will transition to cold, dry conditions with strong offshore winds out of the usual gaps and passes as dense air spills southward under the trough. In particular, expect gusty winds in Thompson Pass Tuesday, likely blowing surface snow around and causing low visibility. Winds will also ramp up in Broad Pass, the Valdez waters, over the Barren Islands, Resurrection Bay, Passage Canal and the Copper River Delta. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)... Skies will gradually clear, particularly over the Kuskokwim Delta, through this evening under a weak ridge. A cold front will track across Southwest Alaska Monday. Highs in the single digits and lows into the minus teens are likely through Tuesday with lower wind chill values. No precipitation is expected. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)... A positively tilted upper level trough extends from the Seward Peninsula southwestward through the western Aleutians. This is currently bringing rain and/or snow showers across the central and eastern Bering and will track to the southeast overnight. It is expected to phase with another low in the Gulf as it approaches the eastern Aleutians. This in conjunction with high pressure building over the North Pacific will strengthen the pressure gradient west of its center. As such, strong northwesterly wind gusts potentially up to 50 mph will develop out of bays and passes on the Pacific side of the eastern Aleutians and Alaska Peninsula on Monday. Winds will diminish from west to east Tuesday as the low departs, however gusty winds will continue west of Kodiak Island through Tuesday. && .MARINE (Days 3 through 5/Tuesday through Thursday)... Forecast confidence in the advertised marine forecast is high. The only question is with strength of winds as a front tracks from east to west across the Bering Sea Wednesday through Thursday. For now, forecast advertises high end gale force southerlies, though there is potential for storm force southerlies, particularly for the western Bering and western Aleutians. && .LONG TERM FORECAST (Days 3 through 7/Tuesday through Saturday)... Beginning Tuesday, an Arctic trough will cross Southcentral and the Gulf of Alaska, with cold and dry air settling in across the entire southern mainland. Offshore gap winds will be in full force along the Gulf coast and Prince William Sound, including the communities of Seward, Whittier, and Valdez. While low level cold air advection and pressure gradients look fairly impressive, the upper level jet is much weaker than in the wind event this past week. Thus, expect overall winds to be weaker than what was observed last week, particularly in the Valdez to Thompson Pass corridor. Blowing and drifting snow and low visibilities will likely plague Thompson Pass again as winds kick up Monday night and Tuesday. This may necessitate issuing a blowing snow advisory or blizzard warning, depending on how much new transportable snow is in place. There will also be some localized gusty winds across the rest of Southcentral and Kodiak Island, as winds accelerate through mountain gaps and bays. Winds will gradually diminish across the region Wednesday through Thursday, while temperatures continue to fall. The Bering Sea and Aleutians will start out quiet on Tuesday as a high amplitude upper level ridge builds in from the west. The ridge will then shift eastward through Friday, with a storm system tracking from near the Kamchatka Peninsula on Thursday way up into the high Arctic on Friday. A trailing front will bring gale force southerly winds to much of the Bering Sea, with potential for storm force winds over the western Bering and Aleutians. With the high amplitude ridge holding over the Gulf and Southcentral and another ridge likely building into the Bering Sea next weekend, the forecast looks dry (and quiet) for much of the forecast area. In particular, after the current snow event ends over the southern mainland, it could be dry for a week or more. After temperatures bottom out Thursday and Friday of this week, expect steadily increasing temperatures after that. && .AFC WATCHES/WARNINGS/ADVISORIES... PUBLIC...Winter Weather Advisory 111 145.
