Synopsis Weak high pressure will produce a break in
precipitation today into tonight. A pair of frontal systems will
give rain at times Tuesday into Wednesday. A ridge of high pressure
aloft will bring about another period of dry weather Thursday into
early next week.

Short term Weak high pressure is building into the region
today for a dry day ahead. Surface gradients are light. Combined
with surface moisture from recent rains, this is producing some
areas of fog and or low clouds. This should dissipate by afternoon
for a partly sunny day for most places. High temperatures today
should be right around normal for the date. A warm front will lift
north over the offshore waters tonight. Light rain will develop
along the coast after midnight tonight then spread into the puget
sound area after daybreak Tuesday. The front falls apart as it moves
inland so there won't be a lot of QPF with it. A secondary system
will be quick on its heels Tuesday night into Wednesday for another
shot of rainfall, rising snow levels, and some breezy to windy
conditions. The front should be east of the cascades by Wednesday
evening with precipitation tapering off ahead of another ridge
building into the region. 27

Long term Models remain in good agreement with an upper ridge
building into the region Thursday through Saturday for another dry
period along with near or slightly above normal daytime
temperatures. By late in the weekend, both the GFS and the euro
retrograde the ridge axis offshore. The euro is more aggressive with
this idea and allows a weak system to clip the area from the
northwest on Sunday. This is a relatively new idea in the models
and, as such, no significant changes were made to the extended
forecast overnight. 27

Aviation Northwesterly flow aloft through Tuesday morning.

Upper level ridge shifting east with next front approaching the area
Tuesday morning. Light flow at the surface becoming southeasterly
tonight.

Stratus deck with ceilings 3000-4000 feet over much of the interior
this morning. Patchy fog along the coast and over the southwest
interior with ceilings below 500 feet and visibilities 1-3sm. Lower
stratus deck, in the 1000-2000 foot range, forming 15z-18z. Both
stratus decks scattering out in the afternoon with just high level
clouds this evening. Increasing mid level deck after 05z with next
front approaching.

Ksea... Confidence not real high in the TAF this morning. With the
light flow in the lower levels potential for a lower stratus deck
near 1000 feet to form under current stratus deck near 3000 feet.

Even if lower stratus deck does not form 3000 foot layer hanging
over the terminal into the early afternoon hours. A few hours of
just some high clouds before clouds increase again late tonight with
next system approaching. ExpectVFR ceilings to continue through
Tuesday morning. Southerly winds 4 to 8 knots into Tuesday morning.

Felton

Marine Light winds will result in relatively quiet conditions
across area waters today. A series of weak frontal systems will
affect the region tonight through Wednesday, bringing at least
advisory-level winds to most area waters. There is a slight chance
that winds could touch gale force over the northern coastal waters
just west of makah bay between 09-18z Tuesday. However, consensus
places winds just below that threshold so will keep an SCA there for
now (as well as most other inner and outer coast waters) and let the
next shift take another look. Once winds diminish Wednesday,
relatively quiescent conditions appear likely through late this
week, and potentially into the weekend.

The other concern is the ongoing king tide cycle. A coastal flood
advisory is in effect around high tide for the next two afternoons
for the coastline of grays harbor county where minor tidal overflow
will be possible. On Wednesday, concerns for minor tidal overflow
shift to the inner coast shorelines. We will be monitoring that
potential.

Hydrology The idea that a couple of weak fronts would just brush
the area Tuesday and Wednesday is trending toward wetter solutions.

Considering how easily the skokomish river made it up to flood stage
with this past front, I think now that the river forecast bears
watching for the middle of the week. For now, I just have the river
starting upward again on Tuesday and do not have a forecast for
Wednesday--but that's the day to watch of the models keep up this
trend. Elsewhere, river flooding is not expected over the next 7
days.

Sew watches warnings advisories

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.
