SHORT TERM
Ridging due to a high pressure out in the central gulf continues through the short term and into the long term, meaning reduced clouds, warming temperatures, and, in this case, a marine layer over the gulf. Currently on satellite, the marine layer has retreated nice to the outer coastal waters; however, the layer will move in later tonight into Icy Strait and Sumner Strait. Current thinking is that the layer will remain intact up until the western portion of Icy Strait. There are smaller probabilities (lower than 25%) that the marine layer will reach Gustavus with visibilities lower than 1 SM. On the southern end, there is good confidence (greater than 80%) that the marine layer will inundate the Western portion of PoW Island and Sumner Strait up until Port Protection. Expect this marine layer to return Sunday night as well, reaching further into the inner channels.

Looking towards the mountains bordering Canada, there is increasing confidence that isolated thunderstorm activity will move into the area both later this afternoon and tomorrow. A few convective cells near Whitehorse are showing rapid development in Canada, moving NE. Looking at NUCAPS soundings, areas directly NE of White Pass look to have CAPE values 500 J/kg or more. White Pass and Haines Customs are the most likely area where thunderstorms could pass tonight and tomorrow, but conditions look favorable (by SE AK standards) for at least one or two cells to develop as far as Glacier Bay.

LONG TERM
Summer is here in the long term. Get out and enjoy it while you can.

Monday a ridge will continue to dominate the region, with the axis retrograding under the influence of a closed low moving along the northern coast of mainland Alaska. Dry, with afternoon sea breezes in the inner channels is the main theme over the next few days. By the end of the week, an extension of a closed low over the Aleutians attempts to form into a longwave trough and move into the Gulf, bringing some onshore flow, cooler temperatures, and increasing PoPs through the weekend. However, models are being a bit too optimistic on ridge breakdown, so have pushed back the timing on this feature.

Threats to coastal and gulf waters remain low, with our swell’s significant deep ocean wave heights remaining under 8ft. With that said, stout 15 to 20 knot northwest winds along the coast will bring short period wind driven waves to the west coast of Prince of Wales and into Dixon Entrance.



AVIATION
/Through Sunday afternoon/...Not a total bluebird day across Southeast Alaska this afternoon or tomorrow, but there are very few places with CIGs below 5000 ft. Light winds from the surface to ridge tops...except of course for Lynn Canal.
Yesterday it was also spicy in Skagway. Today the challenging winds on final are in Haines
And for tomorrow
either or both.
No impactful PIREPS today and I suspect there will be few if any tomorrow. One thing to watch out for is thunderstorm activity approaching from British Columbia and The Yukon. More often than not, these CBs will weaken as they cross the ice field & Coast Mountains, but keep an eye out for them, as they are currently in the forecasts issued by Juneau and the AAWU for our side of the border. As always, PIREPS to the FSS even during good flying weather are appreciated. Good SEAK pictures from aloft and fan mail can be sent directly to WFO Juneau (juneau.weather@noaa.gov).

AJK WATCHES/WARNINGS/ADVISORIES
PUBLIC...None.
