Update An upper level ridge will build offshore tonight and
will be the dominant influence across the region on Wednesday.

Skies remain mostly overcast this evening, however with ample low
level moisture and light winds across the area, patchy fog has
already started to develop in portions of the southern interior. A
few recent observations along the sound have indicated a few spots of
light drizzle as well. Have only made minor adjustments to the
forecast this evening to include areas of fog and drizzle. Otherwise,
the previous discussion below applies, with updates to the marine
and aviation sections. Sb

Prev discussion issued 238 pm pst Tue nov 12 2019
synopsis... Upper level ridge building offshore tonight moving over
western washington Wednesday. The ridge will shift east Thursday
with the next front arriving Thursday night into Friday. Another
system will move into western washington over the weekend.

Short term today through Thursday ... So much for any breaks in the
clouds this afternoon as current satellite shows gray skies over
much of the cwa... But at least the rain has tapered off as expected.

Made mention of a potential fog threat tonight but upon looking at
current satellite trend... Finding it difficult to believe that skies
will clear to the point where this would be a widespread concern.

Might still occur over the more prone locations however... Such as
portions of the SW interior. As the upper level ridge
strengthens... Fog might be an issue for Wednesday night into
Thursday morning... But that is for a future shift to determine.

Models remain consistent keeping conditions dry under the ridge
before the feature exits Thursday with the next frontal system
approaching the coast Thursday night.

The upper level ridging will kick off a warming trend starting
Wednesday with highs in the mid 50s then warming further into the
mid to upper 50s Thursday. Lows will head in the opposite direction
with lows tonight in the lower to mid 40s while falling a bit
Wednesday night. Most locations will be generally in the lower 40s
although temps in the SW interior look to dip down into the mid to
upper 30s. Smr
long term Friday through Monday ... Models remain in good agreement
for the frontal passage during the day Friday bringing the return of
precip to the area. This system will exit Friday night and a weak
upper level ridge will nudge into the area. 12z data... Like the 00z
data prior... Is doing a better job of lining up unlike solutions
from 24 hours ago. As such... Models in better agreement that the
amplitude of the ridge will be just enough to keep most of the
rainfall expected for the first half of the weekend weekend to be
just north of the area... Possibly spilling over the canadian border
into far northern portions of the CWA at worst. It does look like
the ridge starts to flatten out Saturday night which may allow for
precip to droop down in W wa Sunday. Some model disagreement in the
details here though as the operational GFS actually proves to be one
of the wetter of the solutions... Bringing some heavier QPF values
into the area while the ECMWF has the dipping system deteriorate as
it sags southward and... As such... Has lighter qpf. GFS ensemble
members generally gravitate toward this ECMWF solution as well. So
while pops are not too different from previous forecast... Definitely
trimmed precip amounts to fall more in line with this thinking
and... As such... Further mitigated any hydro concerns at this time.

Models prog an upper level low to start working its way toward the
area for the start of next week... But disagree on timing. Smr
aviation... An upper ridge will move over the area tonight and
Wednesday with northwest flow aloft. At the surface, weak onshore
flow will switch to offshore tonight as high pressure moves into
eastern washington. The air mass is moist and stable. Low clouds
will be widespread tonight and Wednesday morning. Recent observations
have indicated that areas of patchy fog have started to develop
across portions of the southern interior this evening. Current
conditions across the terminals remain mostly ifr to MVFR this
evening, with a few areas of lifr for terminals in fog. Fog and
low clouds should scatter by early Wednesday afternoon.

Ksea... Low clouds will be prevalent through Wednesday morning and should
scatter around midday. Recent observations have indicated light
drizzle at the terminal. With ample moisture in the low levels,
could see this trend continue through the evening hours.

Southeasterly winds 3-6 knots will become light and variable
tonight and then northerly on Wednesday. Schneider borth
marine... High pressure will move over eastern washington this
evening, allowing for offshore flow to develop across the region.

Winds will remain calm across the waters on Wednesday, with
offshore flow continuing into Thursday.

A front will then move through the area Thursday night and Friday
morning, bringing small craft advisory strength southerly winds
to the coastal waters and parts of the inland waters. A second
front will move through the area Saturday and Sunday for another
round of advisory level winds most waters.

There will also be west swell 10-13 feet over the coastal waters
from Thursday night through Sunday. Schneider borth
hydrology... River flooding is unlikely through Saturday. Model
solutions continue to back off on significant precipitation
Sunday... Although some might still be possible over the olympics.

This may warrant some further scrutiny for the skokomish... But
remaining rivers should not be too terribly impacted. Plenty of
uncertainty in the forecast at this point but for now the threat of
flooding Sunday and Monday is reduced. Felton smr
