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 May 26, 6:07 PM AKDT, 9 hours 50 minutes earlier.
Area forecast discussion, May 26, 6:07 PM AKDT, 9 hours 50 minutes before
Southcentral and Southwest Alaska Forecast Discussion...CORRECTED National Weather Service Anchorage AK 607 PM AKDT Sat May 26 2018 Resent with updated Long Term Discussion... .ANALYSIS AND UPPER LEVELS... A nearly stationary gale force low centered over the Eastern Gulf continues to bring primarily just cloud cover to the Gulf Coast and areas of Southcentral, but this is beginning to clear as high pressure from the Mainland approaches from the west. Slightly further to the north from the Kuskokwim Valley into the Copper River Basin skies were clear for much of the morning, allowing for enough heating to allow for convection to begin developing by early this afternoon. This is occurring along the southern edge of the thermal trough that stretches into the interior, and will the focus for isolated thunderstorm activity this weekend. The weak ridging over the Mainland is much stronger and widespread, which has allowed for widespread stratus to continue over much of that area. Gusty northwesterly winds are also blowing from the Eastern Bering into the AK Pen, which should continue into late Sunday as the ridge axis approaches from the west. && .MODEL DISCUSSION... The models remain in very good synoptic agreement through the holiday weekend, so forecast confidence remains generally good. There is some question as to how much shower activity will continue into late this evening from the weak easterly wave that will rotate around the Gulf low, leading to slightly lower confidence in the rainfall forecast over the Gulf Coast and Southcentral overnight tonight. && .AVIATION... PANC...VFR conditions and light winds will persist through Sunday. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)... As the low in the eastern Gulf weakens through Sunday the thermal trough will push south through Southcentral Alaska. This will allow for diurnal showers around the area with the chance for thunderstorms to develop in areas around the Copper River Basin, Talkeetna Mountains and the Alaska Range this afternoon/evening. This setup will remain similar on Sunday with the chance for thunderstorms extending south to the western Chugach and Kenai Mountains. The diurnal pattern will also allow for some clearing of cloud cover overnight into the early afternoon with temperatures reaching the mid 60s in the Susitna Valley and western Kenai Peninsula Sunday afternoon. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 through 3)... Thunderstorms are already firing in the Southern Kuskokwim Valley and Bristol Bay and are expected to continue through the evening with the unstable air aloft. By tomorrow, the thermal trough will weaken and move slightly eastward, which will limit the chance for thunderstorms to the northeast corner of the area, up near the Alaska range. Elsewhere in Southwest, Sunday should be a fairly nice day, although along the Kuskokwim coast, clouds may prevail with a chance of fog in the morning as the northwest flow brings more moisture to the area. The upper level ridge continues to move eastward over the area on Monday, continuing dry and stable conditions before a front brings rain to the outer coast starting Monday night. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 through 3)... The ridge in place over the Bering Sea today continues a pattern of low clouds across most of the region, although the far Western Aleutians is beginning to see the effects of an approaching front. This front will continue to move across the Bering Sea tomorrow and Monday as its parent low moves northward towards the Kamchatka peninsula. As a developing wave moves into the base of the trough near the central Aleutians, the force will become a gale force front with the possibility of a few storm force gusts south of the chain. By Monday night, the front will have crossed much of the Bering Sea, switching the winds to mainly southwest and bringing the parent low down from the north. Air aloft associated with this system is fairly warm, so strong winds are not expected behind the front and the precip will remain liquid. && .LONG TERM FORECAST (Days 3 through 7...Tue through Sat)... As is often the case with the extend portion of the forecast, there is decent agreement among the models early on before slowly (and surely) starting to diverge from one another. This leads to fairly high confidence in the pattern to start the week, but lower and lower confidence as we move towards the first weekend in June. To start things off, a low over the Western Bering will continue to weaken as it slings a front through the West Coast. This will make for rather dreary, wet, and windy day for SW AK Tue. Convection (mostly showers with some isolated thunderstorms) will be likely east of the AK/Aleutian Ranges across the rest of southern AK. The front shears apart in the lower elevations as it tries to cross those mountain ranges into Wed. However, the more potent upper- level trough will eject over the southern mainland. With plenty of low-level moisture, moderate instability with a cold pocket aloft, and decent lift, expect showers to encompass most of the mainland. The heaviest precipitation will fall over the southwest. This trough could also drop 850mb (5,000') temperatures about 5 degrees Celsius making both Wed and Thu rather cool and wet. However, by late Thu-early Fri, most models are now pointing to a fairly strong noise of a ridge from the Pacific pushing into the state. This would dramatically change the weather to a much drier and warmer pattern. Most models hint at this feature at least lasting 1-2 days. But the ECMWF is showing signs of closing off the high. If this were to happen, we could move into a very summer-like pattern for much of the early part of June. As we said at the onset of the discussion, the farther out in time, the less we rely on any given solution. However we have trended the forecast slightly warmer and drier for next weekend and we will be monitoring the progress of the ridge. && .AFC WATCHES/WARNINGS/ADVISORIES... PUBLIC...None.
