Southeast Alaska Forecast Discussion National Weather Service Juneau AK 559 AM AKST Tue Nov 28 2023

SHORT TERM
/ through Tuesday night / Tuesday is the break day this week. Majority of the showers across the panhandle are over, with only some weak showers moving from the Gulf of Alaska into the coastal area of the panhandle in the western flow. Should have fairly light winds over the panhandle and inner channels today and tonight, combined with the partly cloudy skies, and wet grounds have some areas of patchy fog or areas of fog in the forecast area. Locally breezy conditions (South gusts to near 30 mph )
around Skagway and Northern Lynn this morning should diminish through the morning hours. Expect winds in Lynn Canal to flop to a north winds this evening.

LONG TERM
/Wednesday through Tuesday/ Generally looking at an active long range period. A broad upper trough covering the Bering Sea and the Western part of AK will dominate the weather over the next week. The various short waves rotating around the low will push various storms through the area from the SW with occasional intrusions of cooler air in the wake of these systems gradually cooling the area down through the week and into the weekend.

First significant system will be showing up for Wed into Thu with gale force winds likely for most of the gulf waters at that time.
Possibility that winds could reach max gale in some parts of the northern gulf due to barrier jet influences. Inner channels will likely just see small craft winds of 25 to 30 kt as the front moves through Wed night. As for precip that will mainly take the form of rain for most areas. Some parts of the north (like the Mendenhall Valley/out the road in Juneau, Yakutat, and the Haines and Klondike Highways) may end up with a few inches of snow. The Haines Highway has the best chance of seeing 4 or more inches of snow so we will be watching that area for any needed headlines later.

Onshore flow persist post-front with showers into late week. The next significant system on the radar is toward Friday as another gale force front moves in from the SW. Some uncertainly with this system as, at the moment, it looks like most of the precipitation and energy is being directed south of the area, but a not insignificant chunk of it may effect the southern half of the panhandle. The weekend features a still active weather pattern with more storm systems possibly moving in from the SW.

AVIATION
Break in active weather pattern will allow for VFR conditions for majority of the panhandle through the day Tuesday, though some patchy fog is possible in the central panhandle in the morning. Southern Panhandle will see MVFR conditions with lingering showers improving through the early morning as a front exits eastward, with clearing skies and overall drier conditions behind it. As cloud cover diminishes and winds slacken, patchy fog will likely be an issue for most of the inside waters tonight into Wednesday morning before a gale force front approaches to stir things up once more.

MARINE
A low will start moving north across the west central gulf and curve back toward Kodiak Island Wednesday and Wednesday night. The associated frontal band starts to spread into the north central and Northeast Gulf coast late Tuesday night and begins working into the panhandle Coastal waters during the day Wednesday. For the most part the strongest winds should be 30 to 40 kt, although in the region of the barrier jet near Cape Suckling it looks as if it increases to rough 45 kt there. The front and trailing wave on it should pass through the panhandle late Wednesday night. There may be a southerly push of winds behind that feature. Advancing towards the end of the week (late Thursday to Friday) another front moves across the southern gulf and looks to impact the southern panhandle with potential gale then too.

PUBLIC...None.
MARINE...Gale Warning for PKZ672.
Small Craft Advisory for PKZ053-643-644-651-652-662>664-671.
