Southeast Alaska Forecast Discussion
National Weather Service Juneau AK

.SHORT TERM...Calm winds, more sunshine, and warmer temperatures
this weekend. A ridge in the gulf and northwesterly flow aloft
will prompt this change in weather for the panhandle. While some
lingering showers will persist this evening, no significant
weather is expected until tonight. With the clearing skies and
lack of sufficient drying, along with downward motion aloft, will
prompt widespread fog concerns for the central and parts of the
northern panhandle.

.LONG TERM.../Monday through Saturday/...Onshore flow across the
area continues as a broad low remains in the northern Gulf. This
low is expected to persist through Tuesday before dissipating and
allowing for an area of high pressure to develop for Wednesday.
Showers are expected to continue with the moisture moving onshore
from the Gulf but are expected to remain light. The next feature
to impact the area will be a front moving into the eastern Gulf
while the parent low remains near Kodiak. This will bring
increased winds and seas to the area as well a return to heavier
precipitation for the panhandle. The heaviest precipitation looks
to remain along the NE Gulf coast but places along the outer coast
could see some heavier periods of precipitation. As we head into
the late week and weekend, the low that has been hanging over the
area shifts into Canada while high pressure builds over the
northern Pacific and tries to expand northward. This would keep
the onshore flow going just in time for the weekend.

&&

.AVIATION...Wide spread shower activity has lead to mostly VFR
conditions with periodic MVFR ceilings as showers move through.
These showers should diminish into the overnight as low level flow
turns more NW. Generally VFR conditions expected through Sunday,
but many Northern and Central inner channel areas may have to deal
with low clouds and/or fog late tonight and early Sunday with vis
and/or ceilings dropping to IFR or lower as a result. Showers
return Sunday night into Monday. Winds have generally been light
with the exception of northern Lynn and Skagway where 20 kt
southerlies have been blowing today. Winds are expected to become
light overnight and into Sunday for most areas.

&&

.MARINE...Winds becoming light air with widespread fog in the Icy
Strait corridor and central panhandle for tonight. Tomorrow will
see a light summertime pattern with Cross Sound, Point Couverden,
and Lynn Canal hitting moderate breeze with possible fresh
breezes. Expect these winds to maximize later in the day as solar
radiation takes effect in both the panhandle and Canada. For the
outside waters, widespread northwesterly moderate to fresh breezes
will be present, rotating around a broad surface ridge in the
gulf.
