Synopsis Moist onshore flow will continue to produce a few
showers across western washington through tonight. Showers will
decrease overnight as the air mass begins to stabilize. The next
low pressure system will mainly track into ca oregon Sunday, with
spotty light rain possible over southern washington. The low will
quickly shift southeast with mainly dry weather Monday. Another
system will track further north with light rain over western
washington on Tuesday. After a weak system brushes the area late
Tuesday, a strong ridge of high pressure will maintain mostly dry
weather into next weekend.

Short term Radar indicates some decent shower activity picking
up over parts of western washington this afternoon. Most of the
instability is aloft with broken low mid clouds across the area.

The flow will begin to back tonight ahead of the next system
heading mainly to our south. This will bring more stable air with
decreasing showers. Light rain will develop along the oregon coast
later tonight with a weak frontal band lifting north into
southern washington by Sunday morning. Models are in good
agreement that the bulk of moisture will be in the mid upper
levels with not much lift. A few spots south of puget sound could
get a few hundredths, otherwise dry or trace amounts with
sprinkles across greater puget sound and the coast.

Global models including both the GFS and ECMWF show a progressive
split flow pattern early next week. A break is expected between
systems Sunday night and Monday. There will be some northerly
surface gradient Monday morning, but some patchy fog should still
be anticipated in prone valleys.

Clouds will gradually increase Monday night with the next system
further north, reaching western washington on Tuesday with light
widespread rainfall. It will be breezy in spots, especially north.

Temperatures will remain relatively mild, above average for
january.

Long term A trailing wave behind the Tuesday system will bring
some additional light rainfall to the area Tuesday night. Once
again, the progressive pattern should allow light rain to quickly
taper off by Wednesday afternoon.

Global models remain in fairly good agreement in showing a
strengthening ridge building over the pacific northwest Thursday
into next weekend. The chance for any precipitation looks minimal
and certainly not significant. The air mass will remain mild with
above average temperatures continuing. Patchy fog will be
possible some mornings when higher clouds manage to clear. Partial
afternoon or filtered sunshine may allow some spots to reach the
low 50s for highs. Milder metro areas will may not fall to
freezing, although colder outlying spots could have some frost.

Mercer

Aviation A minor shortwave will sit over W wa into this evening
keeping upper level flow generally westerly before becoming
southwesterly late tonight and early Sunday. Low level surface flow
remains from the south to southwest and is expected to remain as
such before shifting north to northeasterly very late tonight.

Cigs generallyVFR over the area... Although some MVFR conditions are
present along the coast and over pwt. There are still showers on the
radar... So any location underneath one of these may dip down into
MVFR as well for a brief period of time. Conditions expected to
generally remainVFR for most locations tonight... Although the usual
fog prone areas will see conditions start to deteriorate during the
overnight hours down into MVFR and ifr.

Ksea...VFR conditions are expected to persist into at least late
morning Sunday. Still some risk for scattered showers but
percentages remain low enough for no mention in taf. Winds will
remain from the south to southwest at 7-12 kts through tonight
before becoming northerly 4-6 kts by 12z early Sunday morning. Smr

Marine Winds continue to gradually ease in the wake of a strong
frontal system that passed over W wa waters in the past 24 hours.

Will cancel scas for most of the waters... However the headline for
the puget sound will remain up as winds there continue to meet
criteria... As per current obs. Have also opted to extend SCA for all
coastal waters and the west entrance of the strait. While winds
there have fallen out of SCA criteria... Swells continue to exceed
sca for hazardous seas thresholds. As such... An extension into
Sunday morning was in order. High pressure will then build over the
waters making for much quieter conditions for Sunday and Monday.

Another frontal system will affect area waters on Tuesday... Albeit
weaker than the most recent system. Smr

Hydrology The skokomish was just over flood stage at potlatch
this morning, but it will continue to fall through tonight. The
skokomish will rise Tuesday and Wednesday a bit, but flooding
seems rather unlikely with those two fronts. Elsewhere, river
flooding is not expected in the next 7 days.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
