.SHORT TERM...The low that was bringing rain showers to the area
continues to move south past Haida Gwaii this morning. In its
wake, clouds and some light rain showers remain over the area but
high pressure is already building into the area from the west.
The clouds and showers will continue to slowly dissipate across
the area allowing for more clearing throughout the day albeit
slowly. Increased the cloud cover for today though as cloud cover
this morning is more widespread than previously thought. With the
cloud cover remaining over the area longer, brought down
temperatures across the area to account for the increased clouds.
Overall though, it is looking like it will be a nice day for most
of the panhandle today.

.LONG TERM.../ Tuesday to Friday night / Tuesday and Wednesday
look to non impact weather days, with a ridge of high pressure
moving through the eastern gulf and panhandle leaving an area of
high pressure near the north central gulf coast by Wednesday. A
low pressure system undercuts the gulf coast area to Southern
Haida Gwaii by Wednesday night.

A larger low moves from the Aleutians into the northern gulf and
the front extends southeast. This front looks like it may be
stalled out over the gulf just off the panhandle or just spread
into the panhandle early Saturday.

.AVIATION...Very quiet aviation weather today. Main concern is
some mid level clouds that are advecting over the area from the
east (or developing in place) this morning. Some of these are low
enough for MVFR ceilings, mainly in the south and near Yakutat.
Otherwise winds are low and VFR conditions are the main rule for
the day.

&&

.MARINE...As a ridge builds in the gulf on Monday, a westerly
component to winds will gradually take hold, further increasing
from clearing skies. East west facing channels such as Icy Strait
will likely have enhanced winds up to 15-20 knots during the
daytime period. Fortunately, swell in the gulf will be mainly
southwesterly, same as incoming winds into the inner channels,
which will limiting seas.

Low level warm air advection aloft moving southeast along the
eastern gulf coast tomorrow morning will bring some enhanced winds
to these areas through Monday. Expect the area of maximum winds
to move from north to south through Monday and Monday night.
