SYNOPSIS

-Lingering rain showers, heaviest over the northern half of the area, through the remainder of the week

-A weak front moves across the north on Friday, with a low moving across south/central SE AK beginning Friday night.

LONG TERM

/ Saturday to Wednesday / Weather front that is weakening and falling apart will finish moving through the panhandle Saturday as the parent low for it was still over Eastern Bering Sea. A broad surface ridge over the eastern pacific is nosing into the southern Gulf of Alaska , but as a result, energy will continue to run over the top and through the Gulf. Showers will continue Friday and into Saturday. Low runs across the southern Gulf of Alaska and passing to the south of Haida Gwaii Sunday afternoon/evening. The rain shield extends north into the southern panhandle. Meanwhile a chance of showers/rain will continue.

After the low passes by, there should be some clearing over the northern Panhandle and NE Gulf coast and working way to the southern panhandle during the late Sunday into Monday afternoon. Right now have low chance of rain for the southern panhandle late Monday.

The next weather system moves into the eastern gulf and then the panhandle area Tuesday and a slow moving system that could see a secondary trailing wave for the Wednesday.

AVIATION.../Until 12Z Friday/

As the front finishes pushing eastward through the remainder of the panhandle today, expect conditions across the region to be in the MVFR/IFR category range this morning, improving to the MVFR/VFR category range, with light rain showers diminishing in coverage as we progress through this afternoon. Conditions lower to the MVFR/IFR category range again starting late this evening for the Northeastern Gulf & western Icy Strait Corridor areas, including PAYA & PAGS as another frontal system approaches & pushes in for Friday. A marine layer may move in with ridging behind the front & mainly impact portions of the central the Outer Coast today, including PASI, with primarily low stratus. For northern Lynn Canal, including PAGY & PAHN, at the SFC, winds will be a bit breezy/gusty out of a southerly direction through the TAF period due to a rather tight pressure gradient between low pressure centered over the Canadian Yukon & ridging to the south. LLWS values will be relatively benign through the forecast period.

MARINE

Inside Waters (Inner Channels): Through Friday morning, for northern Lynn Canal, expect southerly winds to around 25 kt & significant wave heights to around 5 ft due to a tightened pressure gradient between a low over the Canadian Yukon & ridging to the south. These winds will diminish to 15 kt or less with waves of 3 ft or less with a more relaxed pressure gradient by the weekend & into early next week. For the rest of the Inner Channels, primarily expect winds of less than 20 kt & seas of around 4 ft or less through the weekend & into early next week.

Outside Waters (Eastern Gulf of Alaska): A weak frontal system will push through the eastern gulf tonight through Friday evening, increasing sustained winds over that entire region to around 20 kt. Winds will increase up to around 25 kt for an area between Icy Bay & Cape St. Elias from the shoreline out to about 20 nm offshore late tonight into Friday afternoon associated with a barrier jet as the aforementioned front pushes through. Significant wave heights should stay between 6 & 10 ft through Friday night with the highest values to the south. Winds increase to around 25 kt for the SE gulf for the latter half of the weekend into next week as a low pressure system marches toward the southern panhandle, increasing seas to between 7 & 11 ft over that area for that timeframe.
