FXAK68 PAFC 160227 AFDAFC Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 627 PM AKDT Wed Apr 15 2026 .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3: Today through Saturday afternoon)... Overall forecast picture remains on track, though there have been some changes to the finer details. Generally expect the cloudier, wetter, and more unsettled pattern to continue, with mostly mild impacts. The biggest hazard we're monitoring is the potential for long duration light snow along the Richardson Highway towards Isabel Pass, with snow amounts on the order of 6+ inches over the course of 1-2 days. There's also uncertainty regarding an upper level trough and associated surface low moving near Eastern Kenai Peninsula from tomorrow into Friday. While this storm is fairly weak, model differences in the speed and track of this system are leading to lower forecast confidence regarding wind speeds and precipitation timing/amounts, especially for the Cook Inlet corridor from Kachemak Bay north into Anchorage and Mat Valley. -KC && .SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3:)... A weak low pressure system in the northern Bering is promoting widespread rain/snow showers over much of the marine areas, including the Pribilof Islands this afternoon. This will push into the Southwest coastline this evening, leading to widespread precipitation across the southwestern mainland. Precipitation will be largely snowfall from Togiak north, and a rain/snow mix or plain rain from Dillingham south. Precipitation will linger in this area through Friday afternoon. A strong North Pacific low rises into the Western Aleutians on Friday. Storm-force winds as well as heavy mixed precipitation and rainfall are expected to impact the from Atka to Shemya. With the low center expected to cross the Aleutians near the Dateline, communities near Adak will see a stronger southerly winds, while Shemya will see strong northerly winds. The low will move northeastward through the Bering, spreading a large swath of precipitation over the weekend. Gale force winds will spread eastward, approaching Unalaska as well as the Pribilof Islands by early Friday evening. A small period of blowing snow may impact the Pribilof Islands early Saturday before temperatures warm. There are still uncertainties regarding the exact strength and track of this low, so changes in the forecast are likely as the low approaches. -CL/JAR && .LONG TERM FORECAST (Days 4 through 7: Saturday through Tuesday)... An active pattern persists Saturday through Tuesday. An unseasonably strong North Pacific storm will have crossed into the Bering Sea on Friday, bringing heavy rain and storm-force winds to the Aleutian Chain as far east as Unalaska; meanwhile, precipitation continues across Southcentral Alaska, maintaining cloudy skies and precipitation through Saturday (some areas may see a short respite late Saturday). By Sunday and into Monday, the low in the Bering Sea will merge into the broad low-pressure system anchored over Mainland Alaska, pulling cooler air back into the region from the north and spreading moderate precipitation across Southcentral; precipitation will likely change into a rain-snow mix across southern Alaska. While specific timing remains unclear at this time, the overall pattern suggests continued unsettled weather for both Southcentral and Southwest Alaska with temperatures likely dropping below seasonal averages. AB && .AVIATION... PANC...Light snow will gradually wind down after 02-03Z this afternoon with visibilities improving; however, a few isolated showers will linger into the overnight hours. Ceilings will also improve to MVFR/VFR by this evening and continue through early afternoon Thur before decreasing as precipitation works back into the region. && $$
