Short term We will see one more day of significantly warmer
temperatures than normal for the northern inner channels as winds
aloft remain offshore. Thereafter, the air mass will cool each
day as onshore winds across all levels press into the panhandle
ahead of a building high pressure ridge over the gulf. Meanwhile
for the coast and the south, temperatures should remain around
normal for the next couple of days with cooling conditions delayed
until Thursday.

Scattered showers associated with an easterly wave passing
westward across the panhandle have resulted in some spotty light
rainfall accumulations. Across the south, stronger dynamics
allowed for some thunder over misty fjords and moderate rain
showers over ketchikan and klawock last night. But the atmosphere
has stabilized. And the deeper moisture over the far south has
stratified into a low cloud deck between 400 and 1200 feet from
metlakatla northwest to sitka. We fully expect this to mix higher
after sunrise and even some scattering by afternoon. We will also
state that there is the possibility of lower ceilings along the
gulf coast tonight as nighttime microphysics reveals the
beginnings of a possible low cloud marine layer south of cape
suckling. But currently tafs are not reflecting this possibility.

Easterly wave activity today will not be as strong as yesterday
and as a result showers will increasingly be limited mainly to
the coast mountains. Some cooling in the lower levels will help
stabilizer the atmosphere and end shower activity over the
lowlands. We have left the thunderstorm threat for hyder and white
pass, but confidence is lower than yesterday.

As the ridge nears our coastline, we will see generally a drier
atmosphere tonight and into Wednesday. While northwest winds
offshore will remain relatively stiff, gradients across the inner
channels will actually fall and winds will slacken. A front will
bring in rain into the central and eastern gulf Wednesday and
Wednesday night. But it should keep offshore until early Thursday.

Small craft winds offshore were kept another day, but should begin
dropping off tonight. CAPE spencer westerly 25 kt never
materialized overnight, and instead blew easterly 10 kt. We have
kept with the idea of 20 kt westerlies for today.

Nam gfs ECMWF canadian model directed a small changes to the
forecast. Forecast confidence is average.

Long term Thursday through Tuesday as of 9 pm Monday the
long range forecast brings more of the same to the wpc solution
set and are finding the ridge at the end of the forecast still
holding on. Thus needed to play the delaying game with pops for
seak through next weekend. Will need to keep an eye on this to see
how long this blocking type feature to the progress flow pattern
will remain.

Some fine tuning of the forecast on Thursday was needed for the
falling apart frontal band on Thursday as it tries move onshore
which was hinted at before however we could add in more details
now. Part of the changes was to lower high temperatures Thursday
for the panhandle, with front trying to spread in should see more
clouds so needed to bump the temps down 3-6 degrees. Not so much
for the Friday high, maybe a half of the Thursday change. After
that though the ridge reforms putting SE ak back into the drier
pattern. The rest of the forecast was generally close so only
minor changes otherwise. Confidence in the long range is average
to above average.

Public... None.

Marine... Small craft advisory for pkz041>043-051-052.
