SHORT TERM
Key Points: - Showers continue tonight with breaks between precipitation before diminishing Saturday.
- A weak trough across the gulf will increase marine winds along the coast Saturday.
Details: Showers diminish tonight as a low weakens over the far northern panhandle. There will be breaks in between these showers. A weak trough will then begin to move across the gulf late tonight into tomorrow continuing rain for the southern panhandle. This precipitation will be light with little to no precipitation accumulation expected.
Winds for northern land areas will be the strongest tonight around 15 to 20 kts before diminishing this evening. The same story is expected for the inside waters as the gradient weakens with the low.
Winds along inside waters and over land will then become light and variable around 10 kts or less through Saturday. The outside waters will increase tonight into tomorrow reaching moderate to fresh breezes. Gusts of 25 to 30 kts along the coast and northern gulf will occur as the trough mover over the area.
LONG TERM
/Sunday through Friday/...Continued wet weather pattern for the mid and long range forecast over SE AK. Advancing low/front Sunday into Monday now tracking further north. Overland winds increasing by early Monday. Moderate to heavy rain should be more widespread but with heaviest amounts aimed at the southern areas with totals of an inch to two inches. The next system coming in late next week is a low pressure system that all ensembles show coming in along the western Gulf from the Aleutian Islands, bringing precipitation to the panhandle around Wednesday into Thursday night.
All ensemble guidance at this time points towards an upper level ridge over B.C. and a low cutting into the western Gulf. Southerly winds for northern areas increase as the pressure gradients tighten.
EFI showing QPF for this time of year across parts of the panhandle Thursday.
AVIATION
/Through Saturday afternoon/...Widespread marginal visual conditions with the occasional drop to instrument conditions in heavier showers this afternoon and into the evening.
As precip diminishes and finally ends, overnight breaks in the clouds will likely result in low scud and possibly even bona fide fog in the usual fog magnets: Juneau, Petersburg, Klawock, Gustavus. Generally dry conditions expected on Saturday with cloud bases lifting slowly through the day. Light winds across SEAK - 10 kts or less. Freezing levels still lower than normal for this time of the year, so departing and arriving instrument flights will have to pay attention to airframe icing while in cloud. No turbulence or LLWS concerns for the short term due to a weak surface ridge situated over the Panhandle and northeast Gulf coast.
MARINE
Outside: A weak trough moving over the Eastern Gulf with narrow band of increasing winds reaching strong breeze (22 to 27 kt). The advancing low Sunday night into Monday now tracking further north bringing more defined SE max small craft low end gale force winds overnight. As parent low moves into NE Gulf small craft westerlies develop then diminish Monday into early Tuesday. Next small craft front tracks in Wednesday. Eastern gulf seas building to 12 ft from swell and wind waves by Monday.
Inside: Saturday, most of the inner channels will be experiencing light breezes (7 to 10 kt), though some areas could at times go calm. Winds will begin to strengthen again during the latter half of Sunday with advancing front. Stronger winds near Clarence Strait/ Dixon Entrance early Monday. Northerly shift with passing front but then return to southerlies. Ridging over the panhandle Tuesday picking up pressure gradient with south winds of 15 to 20 kt, mainly for NS channels such as Lynn Canal.
