Southeast Alaska Forecast Discussion National Weather Service Juneau AK 337 PM AKDT Mon Apr 29 2024

SHORT TERM
Dry, settled weather inundates the short term forecast with a broad surface ridge across the panhandle. While cloud cover continues for much of the northern half of the panhandle including Yakutat, do not expect them to stay around pass this evening. As soon as the clouds depart, expect to see the familiar sunny skies of spring later this afternoon and tomorrow with a pleasant sea breeze. During the overnight, a marine layer is expected to move into the Yakutat area, with some possible light drizzle.


LONG TERM
/ Wednesday to Saturday night / A short wave will move from the southern gulf southeast towards the Pacific Northwest by Wednesday night and as another closed low moves out of the Bering Sea across the eastern Aleutians by early Thursday.
This upper level feature also looks to be tracking in a similar path to the southeast Friday. A larger low moves into the Bering Sea Friday and Saturday while drifting east.

Weak high pressure over the eastern gulf and panhandle are holding in place through Thursday. A weakening occluded front is strung out over gulf Friday maybe approaching the panhandle Friday, although beginning to think that will be held back and it wont be until late Friday and Saturday the front the stronger low over Bering Sea Friday and Saturday will push into SE AK Saturday. So dry weather into Friday and rains returning for the weekend.

Am not expecting any winds over 20 kt until the weekend time frame and those will be starting over the outer gulf waters.

AVIATION
Quiet weather over the next 24 hours. Biggest challenge is how far the marine layer penetrates into the inner channels overnight. Thinking MVFR develops in Icy Strait east of Glacier Bay, with IFR CIGS under the layer west of Glacier Bay.
Areas of fog likely in the morning near Klawock and Yakutat, burning off by late morning.



MARINE
A developing marine layer in the NE gulf coast will advect southward, bringing lower visibilities and some possible drizzle. Currently, a modest amount of low clouds over the gulf will descend, forming the basis for this marine layer. Expect for this layer to infiltrate into Yakutat Bay Entrance and Cross Sound, but not much further. During the morning on Tuesday, the marine layer will retreat with continued high pressure over the panhandle. Mostly light to 10 knot winds for the inner channels with a northerly component. Lynn Canal is the exception, with southerly winds, possibly increasing to 15-20 knots depending on daytime heating in the north.
