Synopsis Cool and showery weather contiues today as another upper
level low moves south through the pac nw. Snow levels will be down
to the higher cascades passes today, although no significant
accumulations are expected. Warmer weather is expected Sun and mon
as ridging over the NE pac builds into the region. However, there
will be potential for cascades thunderstorms on Sunday and Monday.

Short term Today through Monday... Satellite images show Friday's
upper low dropping down into northeast california early this
morning, but with another rapidly moving down the british columbia
coast. Surface observations showed a few sprinkles across the
region, but overall showers showing up on radar were almost non-
existent. With continued low level onshore flow today, low levels
will remain moist, but model time-height cross sections of moisture
show deeper moisture arriving this afternoon with the next upper
low. With deep moisture showing up, expect showers to become more
widespread during the day today, and also likely heavier than most
of those experienced yesterday. Onshore flow ahead of the low will
enhance the precipitation later today over west facing terrain,
especially on and near the west slopes of the cascades. Similar to
yesterday, temperatures will be below normal with the clouds,
onshore flow and cool pool aloft moving across late in the day.

As the low continues to drop south down the californai coast
tonight, the main chances for showers will also sink south out of
the region. By Sunday models consistent in showing the low level
flow becoming more northerly and 850 mb temperatures quickly
rebounding back up to around 8c by 00z Monday. This should result in
a mostly dry day for the western part of the forecast area, with
valley temperatures climbing back into the 70s. A northeast mid
level flow and instability moving in from east of the cascades will
bring a chance for showers and thunderstorms initially to the
cascades. The northeast steering flow however suggests some threat
for showers and thunderstorms to drift west into the valleys late in
the afternoon to evening.

Monday present a similar situation to Sunday, but with the upper low
shifting east to utah and arizona. This effectively turns the mid
level flow more northerly over the forecast area. Some instability
remains over the cascades Monday, keeping a chance for showers and
thunderstorms going, but the steering flow makes it less likely to
see the showers drift west of the cascades. Perhaps a couple degrees
of warming can be expected Monday, but a continuation of low level
onshore flow is likely to hold valley temperatures in the 70s again.

Long term Monday night through Friday... No change. Previous
discussion follows. The broad upper-level ridge that has been
positioned off the west coast finally shifts inland into british
columbia on Monday. Because it will be so far north, this will allow
for a shortwave trough to slide just to our south on Monday night
into Tuesday. This brings showers and perhaps a few evening
thunderstorms to the cascades. Chance for showers comes to an end
after midnight Monday night. Another shortwave passes to our south
on Tuesday, but there is only a slight chance of some wrap-around
precipitation to clip our lane county cascades Tuesday afternoon and
evening. During the latter half of next week the forecast becomes
more difficult as the models don't have a great handle on the
pattern until Friday when there's a fairly good signal that a zonal
flow pattern is setting up for next weekend. -mccoy &&

Aviation As of 0930z, the forecast area was in between
weather systems with generalVFR conditions inland and MVFR along
the coast. Expect this to persist through about 15z, with
occasional ifr in periods of drizzle along the coast. Next low
pressure system moving in from the north will increase rain or
shower coverage across the forecast area by midday, continuing
through the afternoon. During this time CIGS will likely lower to
MVFR inland as rain becomes steadier. Coastal areas may see more
of a showery mode to precipitation, as they will be closer to
the cold pool aloft and thus less stable. Expect rain to slowly
taper off from north to south overnight, but MVFR is likely to
linger for most of the forecast area through at least 06z this
evening.

Kpdx and approaches...VFR CIGS in the 4000-5000 ft range early
this morning are expected to gradually deteriorate to MVFR in
increasing -ra by afternoon, with fairly steady -ra possible for
the afternoon hours. Precipitation is expected to slowly taper
off from north to south this evening, though MVFR CIGS are likely
to persist. Weagle

Marine Seas appear to have reached their peak across most of
our waters overnight, with 10 to 13 ft seas due to fresh swell
from our burst of n-nw wind Friday and Fri night. Winds have
been gradually easing and backing overnight; expect this trend to
continue as low pressure coming from the north displaces the
stronger northerly gradients into the offshore waters today.

Still, our outermost waters... About 40-50 nm or more offshore...

may continue to experience gusts 25-30 kt through this afternoon.

The proximity of the stronger n-nw winds will likely keep seas
above 10 ft into this evening for our outermost waters, while the
lack of windwave contribution allows seas closer to the coast to
gradually drop below 10 ft today.

A surface thermal trough along the south oregon coast is
forecast to strengthen sun, which will result in 20-25 kt gusts
for pzz275 and possibly into pzz255 Sun afternoon. Weaker
gradients Sun night through early next week will generally
result in wind speeds 15 kt or less. Seas eventually fall to
around 5 ft Sun night or Mon as winds remain moderate Monday and
Tuesday. Weagle weishaar
