166 FXAK67 PAJK 031315 AFDAJK Southeast Alaska Forecast Discussion National Weather Service Juneau AK 515 AM AKDT Thu Apr 3 2025 .SHORT TERM.../Through Thursday night/ Key Messages: - Another dry day is ahead for SE AK. - Light winds continue across the panhandle and marine waters increasing Thursday afternoon. - A strong system brings Gale force winds to the Gulf of Alaska and the coast late Thursday night into the weekend. Details: An upper level ridge continues to keep the panhandle dry before a strong low in the gulf increases winds and precipitation Friday. For Thursday, similar to the start of the week, high temperatures will be in the 50s, wind speeds will remain light, and cloud cover will remain minimum. This will all start to change late Thursday night into Friday. As a strong low continues to approach the gulf, an associated front will increase winds and wave heights in the gulf late Thursday. Southeasterly gales will develop along the front as it approaches. These stronger wind speeds will continue to move toward the panhandle through Friday. Along with increased winds, noticeable cloud cover and rain will be associated with the front. This active weather will then continue through the weekend. See the long term forecast discussion for more information. .LONG TERM...The deep low forming in the gulf is currently moving northeast with models dropping as low as 970mb as the front reaches the outer coast. A weak atmospheric river will provide plenty of moisture to help fuel this system and bring an end to the nice weather we`ve been experiencing. This front will be accompanied by strong gales and sea heights possibly exceeding 18 ft off the coast in the eastern gulf. This system is expected to bring elevated winds to the inner channels, with the potential for gales near channel entrances. Temperatures will continue to rise through this system before slowly falling through the next week. Precipitation associated with this system will impact the panhandle through Saturday peaking overnight into Sunday and lingering through the beginning of the week. The northern and central coastal regions will experience the onset first, as well as the highest accumulated amounts as the front moves eastward. Yakutat is expected to receive the most precipitation with 1-3 inches through the weekend. The majority of impacts will occur Saturday afternoon, and the active pattern is expected to continue through the rest of the week. && .AVIATION.../ Through Thursday / Another day of minimal hazards to aviation. Predominately clear clear skies over the panhandle although a lower level marine deck brushes along coast of Prince of Wales Island. Winds for Southeast Alaska will remain on the lighter side, though overnight winds along the outer exposed coasts up to 15 to 20 kt. && .MARINE...With a weak pressure gradient, Inner Channel winds will remain largely around light breezes, occasionally reaching moderate breezes through Thursday night. Marine winds and waves are expected to remain on the quiet side until late Thursday into early Friday when a gale force front moves into the Gulf. Late Thursday night winds offshore will start to increase to gales as winds along the coast will increase to strong breezes. As the front continues to approach, winds will continue to increase into Friday. By Friday morning, into Friday evening, southeasterly gales will be located along the coast and the far northern Gulf of Alaska. Seas are expected to increase along the outer coast with this front with peaks near 20ft along the outer coast Friday night before winds decrease again. && .AJK WATCHES/WARNINGS/ADVISORIES...
