.SHORT TERM.../Through Wednesday night/

Key Messages:

- A dry and sunny day is ahead for SE AK.

- Light winds continue across the panhandle and marine waters.

Details:
An upper level blocking pattern continues to keep the panhandle
dry and clear as we reach mid week. Wind speeds have diminished
remaining light throughout the rest of the day. This weather
pattern and clear skies will continue to allow for slightly above
seasonal temperatures throughout the day with steady low
temperatures at night.

.LONG TERM...Dry conditions remain until Friday. Winds have
decreased to southerly light breezes for the majority of the
panhandle preceding the gale force front expected to reach us
Friday night. Temperatures continue to rise slowly through the
week, with the majority of the panhandle expected to see highs
near or above 50 degrees going into the weekend.

The deep low forming in the gulf is currently moving northeast
with models dropping as low as 975mb as the front reaches the
outer coast. This front will be accompanied by strong gales and
sea heights possibly exceeding 18 ft off the coast in the eastern
gulf. This system is expected to bring elevated winds to the
inner channels, with the potential for gales near channel
entrances. Precipitation associated with this system will impact
the panhandle through Saturday peaking overnight into Sunday. The
northern and central coastal regions will experience the onset
first, as well as the highest accumulated amounts as the front
moves eastward. Yakutat is expected to receive the most
precipitation with 2-3 inches through the weekend. The majority
of impacts will occur Saturday afternoon, and the active pattern
is expected to continue through the weekend.

.AVIATION.../ Through Wednesday night / Another good day to fly
around Southeast Alaska with no hazards anticipated. The few
clouds should be high level although there is a patch of mid level
clouds around Sitka this morning. Winds to remain fairly light,
midday sea breezes possible, but probably not enough to cause
significant turbulence or wind shear.

&&

.MARINE...Marine winds and waves are expected to remain on the
quiet side until the end of the week when a gale force front is
expected to move into the Gulf by Friday. Southerly gales along
the eastern Gulf of Alaska start Friday morning lasting into
Saturday before dissipating. Seas are expected to increase with a
southerly swell as this front reaches the coast. Wave heights
along the outer coast peak near 20ft Friday night before starting
to decrease.
