Synopsis Dry and mild weather today before a cold front spreads
light rain and cascade snow across the region tonight. Some
showers may linger over the cascades Saturday morning, but otherwise
the day will be dry, but cool. Dry weather continues Sunday into next
week. Temperatures are expected to warm well into the 70s next week
as a thermal trough settles over NW oregon and offshore flow
develops.

Short term This afternoon through Tuesday... Dry and mild weather
continues today with increasing high clouds ahead of an approaching
front. A warm front brushes by to the north this afternoon with
little impact to the weather. Radar shows some echoes moving inland
this afternoon with the front, but surface observations and webcams
confirm that precip is not reaching the ground at this point.

However, the cold front will produce light rain along the coast this
evening, moving inland late tonight. Snow levels will be around 5000
feet for the south washington cascades and 7000 feet for the
cascades of lane county when the precipitation arrives tonight. The
snow levels then lower to 3500-4500 feet Saturday morning as light
showers linger over the cascades. The highest forecast rainfall
amounts this afternoon through Saturday afternoon are around 0.20
inches along the north coast, the willapa hills, and the south
washington cascades. In other words, rain will be light. The
willamette valley, especially south of salem, is not expected to see
much rain at all (0.01-0.05 inch). The cascades can expect a few
inches of new snow with no expected impacts for the cascade passes.

A few showers will linger over the the cascades and across extreme sw
washington Saturday morning, but most areas west of the cascades will
remain dry Saturday. Cool and cloudy conditions with onshore flow are
expected Saturday in the wake of a cold front. Dry weather continues
Sunday with surface high pressure building over the area. A shortwave
upper trough may keep some clouds around and somewhat limit heating
Sunday, but the afternoon temperatures will still peak slightly above
the seasonal normals.

A sharp upper ridge moves over the pacific NW Sunday night through
Tuesday, continuing dry weather. A thermal trough develops along the
coast Sunday night and persists through Tuesday for offshore flow and
a warming trend. Models continue to warm from run to run, and 80
degrees now seems likely in the valley by Tuesday. Bowen

Long term Tuesday night through Friday... Models continue their
agreement in showing continued high pressure and dry, warm conditions
through much of next week. Have warmed the forecast further Wednesday
and Thursday, reflecting guidance trends.

Models have even come into general agreement on the track of an upper
low which moves south off the west coast through midweek. This low
looks likely to be the source of the next rain chances in the long
term period as it tracks back north late in the week and sweeps a
trough across western oregon starting Friday. As it passes, it's
likely to force some shower development, with both the GFS and ecmwf
indicating precipitation accumulation starting Friday. Have kept
slight chance pops Friday, although will need to up them if model
solution remain consistent in the coming days. With the upper low
tracking from the south, the environment should be warm with snow
levels well above the cascade passes, i.E. Rain for the cascades.

Bowen

Aviation 06z TAF package: have slowed down the overall
arrival of the cold front by a few hours per amendments so far
this evening. Expect a few hour period of MVFR CIGS with the
front mainly along the coast. MVFR CIGS may hang on toward 18z,
but should dissipate fairly quickly thereafter. Inland, it
appears CIGS will remainVFR as the cold front shears apart. If
anything, CIGS may briefly fall to 020-030 with the immediate
frontal passage. Northerly flow develops after 18z and then may
take a weak offshore component. Should see mainly high clouds
thereafter but with a little bit of fair weather CU building over
the terrain through 22 03z.

Kpdx and approaches...VFR continues through tonight under
increasing mid and high clouds. Light rain, with possibly brief
MVFR CIGS during the frontal passage 08-10z. ExpectVFR conds
thereafter. Jbonk

Marine Only made minimal changes to this evening. Main changes
were to refine the timing of the advisories (especially for the
central oregon coastal waters) to narrower windows based on a
slight slowing of the front and with model data currently
running about 1 foot above current buoy obs. Jbonk
previous discussion follows: a front moving eastward across the
waters tonight will bring small craft advisory level wind gusts
of 25 to 30 kt to the waters. Expect the strongest winds across
the northern waters. Seas will climb into the 9 to 12 ft range by
early Saturday before subsiding Saturday afternoon.

Thermal low pressure over northern california will build
northward along the oregon coast over the weekend. This will
allow a summer-like northerly wind pattern to develop over the
weekend. Winds may turn offshore for a day or two early next week
with gusty winds of 20 to 25 kt possible across the waters
adjacent to the coastal gaps. Surface high pressure looks to
return to the northeast pacific towards the middle of next week,
which should result in winds turning lighter with seas remaining
under 10 ft. Neuman
