920 pm pdt Sat oct 21 2017

Synopsis Rain, heavy at times especially in the mountains, is
expected to continue tonight and into Sunday morning. River flooding
is expected for some locations. Snow in the mountains will
transition to rain in the passes this evening as a warm front passes
through. Winds will be breezy to locally windy tonight. Rain turning
to showers Sunday will end by Monday. Tuesday will be dry. After
some light rain Wednesday, dry weather should return.

Short term Temperatures continue to climb in the wake of a
passing warm front... Or at least here at the forecast office... As
the temperature at 6 pm pdt was around 51 but has since climbed to
57 at the time of this writing. Looking out to the remainder of the
cwa... Seeing a fair number of mid to upper 50s from observing
sites... Particularly along the coast and in the south sound area.

With upper 40s to low 50s still present from a line from port
angeles to everett to points north... Can see where the warm front
has not quite passed yet as of 8 pm pdt.

The big story for tonight continues to be rain. Radar estimated
precip rates typically ranging from 0.1 to 0.3 inches per hour with
heavier rainfall rates mostly contained to thurston... Lewis and
pierce counties with estimated rates exceeding 0.5 inches per hour.

Rainfall rates in the middle ground... 0.3 to 0.5 inches per hour are
popping up north of there though... But remain scattered and
generally confined to higher elevations. Still have some higher
intensity echoes over the western half of the CWA and those have yet
to make their way eastward... So bulk of any flooding concerns will
likely occur during the overnight... If they happen at all. Reasoning
for saying that is that a back end to the precip is already visible
on current radar... As it looks like the NW tip of the olympic
peninsula is already out of the action. Current 00z run of the gfs
shores up a little faith in current rain being a bit more
progressive... But with plenty of activity on current radar and a
guaranteed wet overnight period ahead... This is a matter more
fitting for the morning forecast package.

Inherited winter weather advisory for snow still looks to be okay.

Obs in the cascades are ranging from mid 30s to around 40... So while
some locations may still be seeing snow or mixed precip at the time
of this writing... The transition to rain appears to be underway and
as such... Suspect advisory conditions will not persist much longer.

Winds over the area are generally on the decrease from the higher
speeds and gusts from earlier today. Still seeing some obs reporting
gusts up to 40 mph... But most obs reporting gusts generally around
20 mph or so. That being said... Current wind advisory also looks
good to expire at midnight tonight.

Rain will turn to showers from the northwest on Sunday. By Monday,
residual showers will end with drier and slightly warmer weather
expected. Tuesday continues to look sunny and warm, with heights
around 590dm. Have added patchy fog to the nights and mornings for
both Monday and Tuesday. High temperatures will be 55-60 Sunday,
mostly low 60s Monday, with some mid 60s Tuesday. Smr burke

Long term From previous discussion... Models remain in good
agreement in bringing a weak front southeast across the area
Wednesday. This will be a fast moving system, will only light rain
amounts expected, and will not have an impact on area rivers. The
gfs ECMWF agree that a strong upper ridge will build over the
pacific northwest Thursday and persist through Friday, and likely
beyond. Expect dry weather but with some areas of fog likely with
light winds over the area. Burke

Hydrology Afternoon forecast and discussion were a little
too aggressive... Based on an hrrr run guilty of the same... But
general trend looks to hold up... If only delayed by a few hours.

Otherwise... From previous discussion... Little change in the thinking
from this morning, other than perhaps a bit of a delay in the onset
of any flooding. The river model now shows minor flooding on the
nooksack and stillaguamish rivers, as well as many of the rivers
from the skykomish southward. The rivers with the best chances to
get to moderate flood stage include the snoqualmie, skykomish,
snohomish, cowlitz and carbon. The skokomish river in mason county
is also likely to flood. In general, flooding will occur on Sunday
but could start as early as late tonight. The flood watch remains in
effect for all of western washington.

The burn scar from the recent norse peak fire presents a special
concern. Increased runoff is probable in the burn area and there is
some chance of debris flows. The goat creek valley and the crystal
mountain ski area are at risk of flash flooding, which could reach
all the way to state route 410. A flash flood watch is in effect for
this small area.

Despite recent heavy rains, there has not been enough accumulated
precipitation to saturate soils. Even after the forecast rain this
weekend, the general threat of landslides and mudslides will not be
significantly raised above the normal level. Burke smr

Aviation Strong west flow aloft will prevail over W wa through
Sunday. A vigorous frontal system will continue moving through w
wa tonight with light to moderate rain, finally moving S of the
area 09z- 12z. Conditions will continue to be a mix of MVFR and
ifr with improvement toVFR conditions expected by 19z for most
areas as the air mass starts gradually drying after 12z behind
the frontal system.

A weak upper level trough will move E across the area on Sunday
for scattered showers and predominantlyVFR conditions.

Ksea... The frontal system bringing light to moderate rain to W wa
tonight will keep conditions ifr through 14z. Conditions are
expected to lift toVFR after 14z but there will still be cloud
layers bkn030-050. Low level winds aloft from fl050-fl100 will
remain wsw around 50 kt through 12z. Surface winds are expected to
rise to s-sw 15-25 kt tonight with some higher gusts possible. Kam

Marine A vigorous pacific frontal system will continue moving
through the area tonight. Overall, winds will gradually diminish
through Sunday morning as the system moves slowly S and weakens.

Gale warnings over the coastal waters, east entrance strait of
juan de fuca and northern inland waters this evening should end at
midnight as winds weaken. Small craft advisory winds will prevail
over most of the remaining zones through Sunday morning. Winds
over puget sound are expected to increase to SCA levels this
evening due to a surge of SW wind. Winds in the central and e
strait are also expected to shift to W this evening and reach sca
levels.

A large SW swell has been generated by the recent frontal systems
which will keep the seas in the coastal waters above 10 feet
through Monday for the near shore waters, and through Monday night
for the outer waters beyond 10 nm. A SCA for hazardous seas can be
expected later tonight to cover this issue.

Weak post-frontal onshore flow will prevail on Sunday. The flow
will turn weakly offshore Monday and Tuesday as a weak surface
ridge forms over W wa. A weak cold front will move S across the
region on Wednesday with potentially borderline SCA winds over the
coastal waters. Kam
