Synopsis Yesterday's low pressure system moves down into the
ameican southwest today and tonight, allowing temperatures to warm
back to, or even a little above normal today and Monday. There is
still risk for showers or even afternoon and evening thunderstorms
to inland areas, but the focus for these will tend to be over the
cascades. Going through the middle part of the week, there is only a
slight chance for showers over cascades, otherwise dry weaher is
expected with seasonably mild temperatures thanks to onshore flow.

Short term Tonight through Tuesday... .The upper low that brought
the rain and cool temepratures yesterday, was down over the north
califoria coast early this morning, heading southeast towards the
desert southwest. With rising heights aloft, the air mass will warm
today back to near or maybe a little above normal as model 850 mb
temperatures are expected to rise to 8 to 10 degress c. The region
remains in the cyclonic flow on the north side of the low however,
which will leave the inland areas open to a chance for showers or
afternoon and evneing thunderstorms rotating in from east of the
cascades. Mid level clouds and some showers are seen on radar and
satellite over eastern washington this morning, with models
generally showing this moisture moving west and then southwest into
the north part of the forecast area later today. Model soundings
suggest potential instability today over the cascades extending as
far west as the coast range, but if clouds are thick enough over the
northern parts of the forecast area, it may inhibit heating
sufficiently to reduce the threat of thunderstorms. For now, will
keep some level of a chance for thunderstorms from the cascades out
to the oregon coast range, but this chance would be sensitive to any
clouds moving in today, or in the case of northwest oregon this
morning, sensitive to the clouds being slow to leave.

As the upper low moves east across arizona and utah Monday, the
region remains in the cyclonic flow on the backsidee of the low.

Model soundings actually suggest this may be the more unstable day
over the cascades thanks to continued low level warming, but the
trigger mechanism becomes a little more iffy as weak disturbances in
the now more northerly flow aloft are difficult to track. Expect the
main threat to be more concentrated over the cascades, although
there is still a small chance for some showers or thunderstorms to
drift west out of the foothills. A couple more degrees of warming at
850 mb and drier ground favor inland temperatures rising over a few
degrees over Sundays highs. A continuation of onshore flow at the
surface will tend to keep coastal temperatures moderated, and make
it a little tough to completely get rid of marine clouds Monday.

Tuesday sees the upper heights build a little more as an upper ridge
pushes onto the coast. Any small threat for thunderstorms will be
confined to the cascade crest by this time under the stabilizing air
mass. A continuation of onshore flow will allow for little change to
temperatures Tuesday, and should bring more clouds back to the coast
Tuesday morning.

Long term Tuesday night through Saturday... No changes.

Previous discussion follows. Ridge of high pressure remains in place
over western canada. The high is far enough north to allow for
shortwave disturbances to slide south and clip our area with a few
chances for showers, mainly in the linn and lane county cascades.

Otherwise, expect fairly nice weather for the rest of the forecast
area through midweek, with marine clouds on the coast and partly
cloudy skies inland. Temperatures will be near seasonal for this
time of year, only a few degrees above normal inland. Next weekend a
more zonal flow pattern sets up over the pacific, but high pressure
remains fairly dominant over the pacific northwest into next
weekend. -mccoy

Aviation General MVFR conditions prevail across the forecast
area early this morning, with areas of light rain or drizzle
lingering mainly south of ksle. Expect this area of precipitation
to diminish over the next few hours. Spotty ifr will be possible
through 16z as the boundary layer remains moist and inversions
are becoming shallower. N-ne winds are expected to increase a
little after 16z, likely mixing out the shallow inversions from
north to south. The northerly component may keep some low clouds
stacked up against southern portions of the willamette valley as
late as 19z or 20z, but these should break up for the afternoon.

Meanwhile, increasing instability throughout the day should lead
to increasing showers and potentially a few thunderstorms over
the cascades this afternoon. With steering flow coming from the
ne, it cannot be ruled out that a stray thunderstorm or two
drifts over the inland valleys this afternoon, mostly after 21z.

Kpdx and approaches... MVFR CIGS with local ifr expected through
16z, then improving toVFR by 18z. Isolated showers will be
possible this morning, then deeper convection is expected to
develop increasing showers and potentially a few thunderstorms
over the cascades this afternoon. There is a chance that a few of
these showers may drift w-sw over the pdx metro between 21z and
03z. Weagle

Marine Seas have finally subsided below 10 ft throughout the
coastal waters, so we cancelled our last remaining small craft
advisories. Moderate n-nw winds are likely across the waters
today, with a few localized gusts 20-25 kt possible mainly across
the southern waters. These gusts are not expected to be
widespread nor prolonged enough to warrant advisories. High
pressure nosing into the pac NW waters will maintain modest nw
flow Monday through midweek, tending strongest with gusts up to
20 kt at times newport southward each afternoon and evening. Seas
are expected to remain below 10 ft. Weagle
