929 am pst Sat dec 16 2017

Synopsis Cool cloudy weather will continue into Monday. Light rain
and cascade snow is expected, but mainly north of a tillamook to
mt hood line through Monday. Snow levels will rise to near or
slightly above the cascade passes Sunday afternoon. Rain and cascade
snow becomes more widespread Tuesday and Wednesday as a cold front
moves across the area. Dry but cold weather is expected after
Wednesday.

Short term Today through Monday... There are patches of icy roads
this morning in the willamette valley. The temperatures last night
dipped below freezing shortly after a rain shower causing lingering
water on surfaces to freeze. These icy roads are accompanied by fog
in some areas too. Temperatures should warm above freezing late this
morning.

Light showers mainly north of eugene will decrease today through this
evening. A warm front passing north of the area will produce another
round of light precipitation late tonight through Sunday. Snow levels
will remain around 3000 feet through tonight then rise to above 5500
feet Sunday afternoon. Most of the precipitation will be along the
coast and the higher terrain, and expect very little rain for the
interior valleys. Rain totals will be light, with less than 0.25 inch
for the higher terrain and less than 0.10 inch for the interior
valleys. Overnight temperatures in the interior low lands should be
warmer tonight (above freezing) with daytime highs on Sunday in the
upper 40s.

Showers will linger mainly over southwest washington and along the
coast Sunday night through Monday as the warm front stalls across
washington state. ~tj

Long term No changes. Previous discussion follows... Monday night
through Friday... We start next week under relatively flat, zonal flow
with a broad ridge off the coast of california and an approaching
trough coming out of the gulf of alaska. We will see our first
widespread rain in a while with this system starting Tuesday morning
and continuing through Wednesday morning, with rainfall amounts
around an inch for most of the area. Snow levels will be falling
through this event, starting around 5000-5500 ft Tuesday morning, and
falling to around 1500 ft by Wednesday morning. Showers will be
tapering off midday Wednesday. 1000-500-mb thicknesses drop down to
523 dam, and 850 temps only lower down to -4c while precip is
falling, indicating no chance for snow down to the valley floor with
this system, though locations in the cascade foothills and coast
range could see a dusting of snow down to 1500 ft on Wednesday as
precip is coming to an end. Good news for skiers is that with ~1 inch
of liquid equivalent, and snow levels starting around 5500 ft, the
resorts could see a foot of snow with this system.

Beyond Wednesday, ridging builds back up over the eastern
pacific and along the west coast. Ensemble members generally agree
on some sort of a ridge over the eastern pacific, though the exact
positioning is in flux. Most models suggest another dry spell
continuing into the weekend, with the return of east winds. Only
difference from this last dry spell may be that model temperatures
in the columbia basin are looking a little colder, suggesting colder
air filtering into the willamette valley as we go into next weekend.

Aviation Conditions are gradually improving with the taf
terminals a mix of MVFR andVFR, except for high end ifr vsbys
at khio. Do expect a broad improvement as a warm front, but many
areas may still flirt with MVFR CIGS at at times through the
evening. Warm frontal rain arrives later this evening and
overnight which appear to drop vsbys back down to ifr for many
areas across the north. Thinner cloud cover across the south may
bring a return to lifr under fog low stratus south of ksle,
including keug at or after 09z lasting through much of Sunday
morning.

Pdx and approaches... CurrentlyVFR conditions however, an advancing
warm front may keep CIGS bouncing down to MVFR at times. Have
very low confidence, however. Most likely scenario is CIGS will
remainVFR through this evening with lower CIGS likely to
obscure the cascade terrain through the evening. Then have
higher confidence CIGS will lower around 05z as rain pushes over
the field overnight tonight through early Sunday. Jbonk

Marine Not many changes for the morning update package. Square
seas are holding on a little longer across the northern waters so
decided to extend the SCA for seas until about noon. Jbonk
previous discussion follows: high pressure offshore bringing nw
winds across the waters this morning. Winds will back later today
as a warm front approaches. South to southwest winds increase
tonight with gusts to 25 kt expected west in zone pzz270. May see
wind gusts to 25 kt over pzz250 sun. A stronger front is modeled
to arrive on tue, and looks like it has the potential to bring
gale force winds. Another front may arrive wed. Then weak
offshore flow is expected to develop in the late week time
period.

Seas are sitting just 8 to 9 ft and are slowly subsiding. However
with periods around 8 to 10 seconds, choppy steep seas are
occurring. Seas will continue to subside through the morning.

Seas remain in the 5-7 ft range later today through mon. The
stronger Tue front will likely push seas into the low to mid
teens before they drop off again during the second half of the
week. Mh
