522 FXAK67 PAJK 291227 AFDAJK Southeast Alaska Forecast Discussion National Weather Service Juneau AK 427 AM AKDT Mon Jun 29 2026 .SYNOPSIS... Key Messages: - Light to moderate showers for the northern half of the panhandle look to continue into the evening before dissipating. - Brief break expected for much of panhandle Sunday, before onshore flow brings shower chances back to the outer coast and central panhandle. - Increased likelihood of clearing primarily for the southern half of the panhandle Sunday lasting into the start of the week. && .SHORT TERM...Satellite and radar imagery show a cloud deck has remained entrenched across the northern half of the panhandle overnight, even as a marine layer has pushed back into the outer coast and parts of the south. Unfortunately, the weather looks set to continue to remain less than idea for the central panhandle and Icy Strait Corridor through at least the first half of the week as a low level ridge contributes to onshore flow and weak shortwaves continue to rotate around the ridge axis and into SE AK. Through the day on Monday, do expect that the cloud ceilings will generally lift through the daytime hours, especially for the southern panhandle where more substantial breaks in the clouds might occur. Periods of drizzle and light rain showers will linger for areas between Sitka and Berners Bay, and along the NE Gulf Coast due to onshore flow. Monday night will see the marine layer redevelop and push back inland, with the stratus deck once more building across the southern panhandle before pulling back off the coast on Tuesday. Temperatures will remain on the moderate side, with low to mid 60s for high temperatures for much of the area, though some locations will likely be unable to break out of the 50s. Low temperatures will be in the upper 40s or lower 50s as cloud cover prevents significant night time cooling. Winds will be similar to yesterday and largely sea breeze driven. Though sea breezes will be limited in strength given the clouds. Breezy conditions for Icy Strait, Northern Lynn Canal, and Clarence Strait through the next few days, along with the SE Gulf Coast. For additional information, see the marine and aviation discussions. .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... With a ridge of high pressure in the Gulf of Alaska, a marine layer is bringing ceilings between 1500-2500 feet across the Alaska Panhandle. Ceilings are expected to generally improve to VFR by 18Z Monday, but showers are once again possible for the Icy Strait Corridor, and near Yakutat as well. After 06Z Tuesday, another round of lower ceilings appears likely with the marine layer building in. As of this TAF package, confidence is lowest in this layer impacting Petersburg and Wrangell Tuesday morning. && .MARINE... Outside (Gulf and Coastal Waters): This morning, westerly/northwesterly winds of 15-20 kts are occurring due to a ridge of high pressure. This strengthening ridge will lead to winds up to 20-25 kts on the southwest side of Prince of Wales Island toward Dixon Entrance through the day Monday. By Tuesday, this ridge will begin to weaken, so winds and waves will begin to decrease. Inside (Inner Channels): This Monday morning, the strongest winds in the inner channels are currently occurring in Lynn Canal, where Eldred Rock is seeing 20 kt southerly winds. With a ridge of high pressure, 10-15 kt northwesterly winds are occurring in Clarence Strait as well. With daytime heating, expect the stronger winds in the Gulf to bring stronger winds into Cross Sound, and near Port Alexander and Cape Decision. The ridge is expected to weaken during the day Tuesday, and should lead to calmer conditions across the inner channels. && .AJK WATCHES/WARNINGS/ADVISORIES... PUBLIC...None.
