062 FXAK67 PAJK 262230 AFDAJK Southeast Alaska Forecast Discussion National Weather Service Juneau AK 230 PM AKDT Sat Jul 26 2025 .SHORT TERM...A near gale force low continues to slide southward in the gulf, bringing high end small craft winds to northern coastal waters in the gulf and a band of precipitation that has largely stayed offshore. The lone area to not dodge this was Yakutat, which saw light rain start early Saturday morning and continue into the afternoon hours. This rain will continue to diminish before pulling out completely along with most of the cloud cover over the area as the low continues its southward crawl. Overall pattern across the panhandle will see general offshore flow aloft with the low becoming anchored over the southern gulf Sunday. This will lead to decreasing cloud cover for a majority of the panhandle, allowing for larger diurnal temperature variations with cooler minimum temperatures in many areas overnight Saturday, but also warmer maximum temperatures Sunday. This further clearing of clouds will also mean areas that saw fog Saturday morning will likely see it once more, though some drying should limit its extent Sunday morning. Later on Sunday for the inner channels, thermal troughing over the interior means sea breezes in the usual areas. Otherwise winds are expected to remain 10 kt or less, with the exception of Clarence Strait which could reach upwards of 15 kts near Dixon Entrance. All and all a relatively quiet end to the weekend is in store for the panhandle with relatively warm and dry conditions. For more on what to expect early next week, see the long term discussion. LONG TERM...Little changes to the relatively stagnant pattern that is Monday onwards. The broad closed low, located in the central gulf, looks to stay in a blocking pattern, with southerly flow aloft directed at the southern panhandle. Multiple shortwaves will move along this flow, which will be the primary rainmakers for Tuesday onwards. While there is high freezing levels associated with the southerly flow and the depth of the moisture is relatively deep with PW around an inch coming into the panhandle, not looking at much precipitation due to lack of significant moisture transport from weak winds. Then, with the terrain in the panhandle, expecting any higher rainfall to collapse as it moves into the panhandle from the waves shearing apart. Highest accumulations look to be on the western coast of PoW island for this reason, with light accumulation inland. Going with this idea, currently have much reduced PoPs from about Kake northward, less than 50% for measurable accumulation in 6 hours. Consider this to be the story for much of the week, with the only areas outside of any appreciative rain chances being Haines and Skagway at less than 20%. && .AVIATION.../Until 00Z Monday/...Most of the Panhandle is starting out with VFR conditions this afternoon. Some airports along the Outer Coast are still dealing with a bit of a marine layer that has pushed into the coast that is giving as low as MVFR conditions. Light winds & decreased clouds will allow for some more FG development again late tonight & into the morning for the PAPG, PAWG, & PAKW areas with CIG & VIS conditions dipping down into the MVFR/IFR category range. The rest of the Panhandle looks to stay VFR through the period. A low over the central Gulf moving southward has frontal bands that have formed around the low that are increasing the winds off the Outer Coast. They have been spreading some light rain to the northeast Gulf Coast into this afternoon. PAYA has been seeing some light rain today. Generally, benign SFC wind & LLWS values are in store for the period. The only thing worthy of noting is that areas that receive less cloud cover & more warming will see sea breezes, this afternoon & tomorrow afternoon. The most significant area will be around the northeastern Panhandle, including PAGY, which will see the strongest & most gusty sea breeze this afternoon, but other areas in the Panhandle getting gusty that receive enough insolation is not out of the question, as well. && .MARINE... Inside Waters: Due to position of the low far removed from the outer coast, winds along the inner channels remain relatively light. Exceptions are some gapflow winds along backside of Douglas as well as localized afternoon sea breezes which could reach upwards of 15 kt, as well as southerly flow coming up Clarence Strait. These winds will diminish into Saturday night, with Lynn Canal likely becoming light and variable due to drainage winds coming down the valleys and the overall weak gradient over the area overnight. Expect more of the same on Sunday, though winds in Clarence will Outside Waters: The near gale force low will continue to weaken Saturday night into Sunday as it slides into the southern gulf and takes up station there through the end of the weekend. Winds along the northern gulf will gradually decrease and turn northerly, while elsewhere southeasterly winds will shift to be primarily easterly. Area of 10 - 12 ft seas in the northern gulf will shift southward with the low while subsiding to 8 - 10 ft. Seas will then further diminish overall as the low in the southern gulf continues to degrade into Tuesday. && .AJK WATCHES/WARNINGS/ADVISORIES... PUBLIC...None.
