Synopsis Another weak upper level disturbance will slide by
to the north of the area late tonight and early Sunday, bringing
seasonable temperatures to the region. High pressure aloft begins to
rebuild and strengthen late Sunday and through early next week over
the pacific northwest, with above normal temperatures across the
region expected.

Short term Saturday through Monday... A westerly flow aloft
Saturday afternoon is expected to continue into Sunday. A weak
shortwave, following on the heels of todays, is expected to cross
washington early Sunday. A weak front with todays system has left a
band of clouds in the low to mid level moisture across the NW part f
the forecast area Saturday afternoon. Klgx radar and surface
observations showed isolated weak showers over southwest washington
and the far north part of the oregon coast range. Will keep a low
pop this evening for the south washington cascades as the remains of
the front continue to push inland. With a continuation of low level
onshore enhanced by a weak shortwave in the north, expect to see
shallow marine clouds redevelop overnight along the southern part of
the coast, and push locally inland up the lower columbia late
tonight and early Sunday. With the modest reinforcement of marine
air overnight, expect temperatures Sunday similar to Saturdays
highs.

Sunday night through Tuesday models agree on the upper flow turning
northwest as an upper ridge builds offshore and eventually shifts
inland as a negative tilt ridge. A thermal induced surface trough is
expected to build up the coast Sunday night and Monday in response
to the upper level ridging, turning the low level flow more
northerly with time. This will reduce considerably any prospects for
a return of marine clouds Sunday night and Monday night. Warming
temperatures in this pattern will see temperatures climbing Monday
and Tuesday, with 850 mb temperatures reaching 22c by 00z,
suggesting highs well into the 90s by Tuesday afternoon despite a
bit of a mid level subsidence inversion suggested in the model
soundings limiting temperatures to something a little less than what
might otherwise be expected for the 850 mb temperatures with an
offshore flow.

Long term Tuesday night through Saturday... A negatively tilted
high pressure ridge continues to build over the west coast through
Wednesday. As the ridge builds on Wednesday, skies are expected to
be clear which will raise temperatures into the 90s. On Thursday,
conditions begin to shift as a shortwave trough moves through the
flow around the ridge. As this shortwave advances towards the west
coast, models begin to diverge which impacts confidence on Thursday
and Friday. The ECMWF brings the shortwave inland farther and faster
on Thursday, while the GFS keeps a majority of the energy off shore
of the northern oregon coast. However, with either solution this
pattern is generally favorable for convective activity, so a slight
chance of thunderstorms and showers are forecast on Thursday
afternoon along the cascade crest. On Friday night into Saturday, a
front along the leading edge of an alaskan low will approach the
west coast which may bring a chance of showers to the coast.

Aviation MainlyVFR across the forecast area as of 0330z,
though MVFR stratus is beginning to develop near the coast north
of cannon beach. Expect low clouds to fill in near the coast
overnight, along with some patchy fog in the coastal valleys.

Some MVFR stratus with CIGS 015-025 msl will likely push inland
into the pdx metro terminals by sunrise Sunday, but chances of
this are lower the further south one GOES in the willamette
valley.VFR conditions will return inland by 19z, though some
MVFR may linger near the north coast into the afternoon. North
winds will become rather brisk along the central or coast Sunday
afternoon with gusts 25-30 kt possible konp southward.

Kpdx and approaches...VFR through this evening, then there is a good
chance for seeing MVFR ceilings with marine clouds spreading
into the area after 11z Sunday morning. Weagle bowen

Marine High pressure will reassert itself over the ne
pacific Sunday, causing n-nw winds to increase across our
coastal waters by afternoon. Winds above 20 kt are likely to
continue uninterrupted through the first part of next week as
both the high pressure system over the NE pacific and a thermal
trough over SW oregon intensify. Increasing wind wave component
will result in increasingly choppy seas Sunday and Monday.

The thermal trough over southern oregon is modeled to build
northward into the north oregon waters toward the middle of next
week. This may push the stronger winds further offshore Wednesday,
while lighter offshore flow prevails for the coastal waters.
