Synopsis Unsettled conditions will continue over the forecast area
through mid-week. Daytime temperatures will remain below normal
through Tuesday, followed by a slow warming trend. Longer range
guidance shows another upper low settling over southwest oregon and
northern california late in the week and into the weekend.

Short term Tonight through Wednesday... It's been a bit of an
unusual weather pattern today. Wrap-around moisture from an upper
level low moving into central california has lead to increasing
shower activity developing along the cascades and drifting eastward
into the foothills and eastern portions of the willamette valley and
clark county wa during the late afternoon and evening. Meanwhile,
moderate onshore flow at the lower levels lead to some weak shower
activity developing along the coast range and moving eastward into
the valley. Over the past couple of hours, there has been some
enhancement in a few of the showers as the two shower bands have
collided. No significant impacts have been noted, but there have been
a few reports of brief heavy downpours. The latest hi-res fcst models
show the precipitation becoming more and more confined to just the
cascades later this evening, then gradually dissipating overnight.

The aforementioned california upper low moves to the desert SW late
tonight. However, another upper low drops southeast into the NE pac
mon. Models in general agreement showing renewed precip reaching the
coast late mon. However, light shower activity remains near the
cascades Mon morning and continues through the day.

The upper low takes the same general track as the current one,
sliding into northern california Tue morning. A west-to-east oriented
700 mb trough is expected to reside over the area tue. Thus, expect
at least scattered shower activity. It appears the favored area tue
will be in the vicinity of the upper low, or SW oregon. Daytime
temperatures will continue below normal Mon and tue. By wed, the
upper flow becomes north to northeast, which will force the best
dynamics and associated shower activity into SE oregon. Would
anticipate a fairly deep marine layer Wed morning. NAM sounding for
kpdx valid 15z Wed would indicate tops to at least 5000 ft msl.

Afternoon temps Wed should be closer to normal. Pyle weishaar

Long term Wednesday night through Sunday... Models agree on the
general pattern going into next weekend, with a large upper-level
ridge building up just off the west coast. This general trend
should help to dry us out going into next weekend, but some
uncertainty in the exact position of the ridge could introduce a few
showers, especially over the cascades as shortwaves ride down along
the eastern side of this ridge. For this reason, have left a slight
chance of showers over the cascades through at least Saturday.

Models show the ridge trying to nose a bit farther east on Sunday,
which will help temperatures climb again, possibly to around 80
degrees in the north willamette valley, lower columbia i-5 corridor,
and hood river valley. This should also shut down any chance for
showers over the cascades by Sunday. -mccoy

Aviation MostlyVFR conditions expected to continue through
the evening. Showers will continue to taper off during this
time, but expect patchy lower clouds, generally around 2000 ft,
to develop after 07z through 12z. Lower clouds will continue
through 15-17z, before again lifting to generallyVFR conditions
after 18z Monday. Gusty south winds will develop along the
coastal areas by 18z and south to southeast winds across the
interior closer to 21z ahead of an approaching front.

Kpdx and approaches...VFR conditions this evening with remaining
showers moving away from the terminal area by 07z. Ceilings will
gradually lower with MVFR conditions likely developing around 12z
and lingering through daybreak.VFR conditions after 17z Mon with
light southerly surface winds. cullen

Marine High pressure remains tonight over the coastal waters
for a period of relatively quiet marine weather. However, a
southeast moving low pressure system will approach and enter the
waters Monday afternoon and evening. Expect stronger south winds
to develop across the waters ahead of the low, with small craft
conditions advisory strength winds across the waters. There
remains the potential for gusts 30 to 35 kt south of cascade head
and beyond 20-25 nm from shore.

As the wind increases, locally-generated steep seas will build,
reaching around 10 ft Monday night. A modest fresh westerly swell
follows the system Tuesday, and is expected to push seas into
the range of 11 to 13 ft.

Later in the week, expect high pressure to again build offshore
with a return of gusty northerly winds across the coastal waters.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
