Synopsis Isolated showers are possible this afternoon and evening
mainly across southwest washington. A frontal system will produce
more widespread light rain Wednesday through Thursday morning. Drier
and cooler air behind the front will help cool the overnight
temperatures a bit Thursday night. Warmer weather is expected for the
weekend.

Short term Tonight through Friday... Lots of strato-cu across the
region early this afternoon under an upper trough. The interior
valleys should progressively clear this afternoon and evening =, but
onshore winds will likely keep CU over the coast range and the
cascades. The onshore winds combined with upper support with the
trough from above may provide enough lift over the higher terrain for
isolated showers this afternoon and evening. South winds develop this
evening as a frontal system approaches. This will maintain dewpoint
temperatures in the mid to upper 50s across the area for two more
muggy nights with low temperatures near 60.

A weak warm front will bring light rain to the coast and areas north
overnight tonight into early Wednesday morning. Although the front is
weak, there is a lot of moisture available in the atmosphere as
modeled tpw values are around 1.4 inches. Models indicate there will
be enough isentropic lift ahead of the warm front to increase the
forecast confidence for measurable rain, and have increase pops
significantly along the coast and higher terrain of SW washington and
nw oregon. A trailing cold front will continue rain chances as it
moves inland Wednesday afternoon and night. Rainfall will be highest
along the coast and higher terrain of SW washington and extreme north
oregon where 0.25 to 0.5 inch of rain is possible from Wednesday
morning to Thursday morning. Barely any measurable rain is expected
for the willamette alley (0 to 0.10 inch), and around 0.05 to 0.15
inch of rain is expected for the coast range and cascades of central
oregon.

Drier north flow moves in behind the cold front Thursday afternoon,
which will allow the dew point temperatures to lower to near or below
50 Thursday night, and the minimum temperatures in the 50s. A weak
shortwave trough may generate some drizzle along the coast Friday
morning, but otherwise expect dry weather Friday with clearing in the
afternoon and day time temperatures warming into the upper 70s. ~tj

Long term Friday night through Tuesday... A high pressure ridge
builds over northwest oregon and southwest washington through Sunday
night. This will keep conditions fairly clear and dry through the
weekend. That ridge will start to weaken as a shortwave, associated
with a low in the north pacific, advances towards the coast. Marine
stratus will fill in along the coast and foothills on Monday. There
is an increased chance of occasional showers on Monday which will
persist through Tuesday. Elsewhere, conditions will remain mostly
sunny.

Aviation MVFR CIGS are starting to redevelop along the coast
this evening, whileVFR conditions prevail inland. A weaker
shortwave moving in tonight should mean inland terminals hold on
toVFR conditions overnight, but models show low stratus back-
building westward off the foothills of the cascades Wednesday
morning, so have included a deck of 2500 CIGS moving into ttd,
sle, and eug, and possibly pdx and hio as well. Better chance for
MVFR CIGS will be midday Wednesday as another weak front will
bring more light rain to areas around sle northward. Most of the
rain will fall along the coast, starting as drizzle overnight
tonight which may bring ifr lifr conditions to ast and onp,
mainly after 08z at onp and later at ast. Models show a mix of
vfr and MVFR conditions Wednesday afternoon and evening inland,
and probably a mix of ifr and MVFR conditions along the coast.

Kpdx and approaches...VFR conditions overnight. Could see a MVFR
deck move in after 12z, back-building westward off the cascades,
but confidence is not high enough to include it in the tafs right
now. Will see another round of light rain starting around 18z
wed which may mean a mix ofVFR and MVFR CIGS Wed afternoon and
evening. -mccoy

Marine The latest 12z run of the high resolution models have
converged fairly well on the shortwave trough that disturbs the
northwesterly flow associated with the north pacific high.

Although there are differences in the strength of these wind
speeds most of the models show significant wind speeds that
warrant the issuance of a small craft advisory. Winds will start
shifting into a southwesterly regime tonight. Wind gusts between
21 and 30 kt in the northern waters for most of the day
Wednesday. The southern waters have an advisory for a shorter
time period late Wednesday as these stronger winds are more
isolated to the north. However, this may change if the winds
extend farther south in future model runs.

High pressure begins to rebuild offshore on Thursday and
strengthens for the weekend. This will result in a return to
northerly winds through early next week. Gusts of 25-30 kt can
be expected for the weekend with the strongest winds beyond 10 nm
offshore.

Seas start in the 3 to 4 ft range, then build to around 8 feet
Thursday morning. Seas will be choppy as this system passes with
the potential for square seas on Thursday morning. Seas will
stay above 5 ft through the weekend.The larger seas are a
product of the increased wind wave height from the short wave
system that moves through Wednesday night into Thursday but also
from a 7 ft swell out of the NW that will be the dominant swell
throughout the forecast time period. -bphillips mh
