582 FXAK67 PAJK 290021 AFDAJK Southeast Alaska Forecast Discussion National Weather Service Juneau AK 421 PM AKDT Sun Jun 28 2026 .SHORT TERM.../through Tuesday night/... A departing short wave overnight has brought drier yet cloudy conditions through the day today. This general trend is expected to remain through tonight with the exception of communities located between Icy Strait and Fredrick Sound, and along the coast from Yakutat to Sitka. The lower levels of the atmosphere look to remain fairly damp while the mid levels are indicating drier conditions. This has led to the inclusion of a rain mention for the previously stated areas, ranging from slight chance to chance (mainly below 45%). The thinking is that models are picking up on low stratus clouds and a marine layer that could bring light precipitation activity. This trend is expected to continue through the day Monday for the area between Icy Strait and Fredrick Sound as another upper level short wave moves over the panhandle, bringing another wave of energy and increasing the potential for lift. The southern panhandle is expected to see some breaks in the clouds through Monday and stay relatively dry through the period, though cloudier skies are anticipated through Tuesday. The panhandle is then caught on the troughing side of an upper level low that is expected to continue the onshore flow. This indicates another day of wider spread precipitation chances for the northern and central panhandle, as well as coastal communities in the southern panhandle. Again, this rain is expected to be more intermittent and driven by low level moisture and lower cloud decks. Temperatures are also expected to be slightly below normal through the period with highs reaching high 50s to low 60s. This is due to cooler air moving across the panhandle in the mid atmosphere despite the possibility for pockets of sun in the southern panhandle. For more on the upcoming weather, refer to the long term forecast below. .LONG TERM... Normal to below normal temperatures look to continue for most of the week, as westerly to northwesterly flow looks to keep cooler, maritime air overhead for longer. With onshore flow at the surface, boundary layer moisture, and weak vorticity advection and divergence aloft, continued rain chances are in the forecast as well. Could see a feature with some substance by the Wednesday timeframe that may bring more organized showers, particularly to the southern panhandle, but nothing that is not typical for this time of year. Similar on the side of winds, with no wind gusts across the land areas of the panhandle looking to exceed 30 mph with the exception of Skagway. && .AVIATION.../Until 00Z Tuesday/...The marine layer continues to impact the northern Outer Coast with lowered cloud ceilings to around MVFR/IFR through the period. It looks to also impact the central & southern Outer Coast & the western half of the Icy Strait Corridor overnight tonight with MVFR conditions as it moves back in. Monday morning, the marine layer will, once again, retreat from the central & southern Outer Coast & the Icy Strait corridor, improving conditions to VFR. The remainder of the Panhandle should generally keep VFR conditions through the period. The exception looks to be around the PAPG area, which may experience some areas of FG, lowering conditions, overnight. As far as SFC winds are concerned, most places should remain rather benign through the period with the exception of the Northern Lynn Canal & Clarence Strait regions, including PAGY & PAKT, which will keep gusty winds through this evening & also Monday afternoon from a combination of a sea breeze & a tightened pressure gradient for PAGY & just a sea breeze for PAKT. LLWS values remain benign through the forecast period. && .MARINE... Outside (Gulf and Coastal Waters): A persistent ridge over the Gulf of Alaska is leading to westerly winds of 15 to 20 kts tonight. Through Monday, northwesterly winds around 20 to 25 kts with seas up to 8 feet are expected to occur from Port Alexander southward toward Dixon Entrance. Into Tuesday, the ridge is expected to weaken, lowering winds along the entire coast with the strongest up to 15 kts along the southern panhandle. Seas are also expected to diminish to 6ft by Tuesday night. Inside (Inner Channels): Winds over the next few days will be primarily driven by the diurnal cycle. Current observations show winds trending weaker to around 10kts this evening as daytime heating decreases. Tomorrow, winds will strengthen up to 25 kts as the pressure gradient due high pressure in the Gulf and thermal troughing in Canada increases. The strongest winds are expected in Cross Sound and the Icy Strait Corridor, with elevated wind speeds also possible for northern Lynn Canal and near Cape Decision. Tuesday, the ridge is expected to weaken, which will lead to overall weaker winds by ocean entrances. && .AJK WATCHES/WARNINGS/ADVISORIES... PUBLIC...None.
