Synopsis Dry conditions over most of western washington this week
with slightly above normal temperatures. A few showers or
thunderstorms are possible most afternoons and evenings over the
cascades.

Short term today through Thursday Another fairly quiet start to
the day again this memorial day with the only item to discuss
regarding current conditions is that some low level stratus fog is
making itself known over some locations. Largest reductions in
visibilities can be found out by arlington and port
townsend... Although patchy fog can also be expected in the usual fog
prone locations such as olympia and hoquiam. These low clouds are
expected to burn off by late morning for most locations... Giving way
to mostly sunny skies by this afternoon.

Upper level ridging over the pacific will start to slowly move
eastward closer to wa today as exiting upper level low pressure
continues its journey into the four corners region. This will set up
continued dry conditions for most of the area while allowing for
wrap around moisture from the aforementioned low to give rise to
afternoon showers and isolated thunderstorms over the cascades.

Those sunny skies and dry conditions will make for a warm day over
the interior lowlands... With most locations hitting high temps in
the mid 70s today. An onshore push expected tonight will ensure that
highs today will be the highest of the week... As this cooler marine
air will knock afternoon high temps back down to around 70 for the
remainder of the near term.

Models remain pretty consistent for the near term period with the
upper level ridge continuing to slowly move east... Keeping
conditions dry over the area except for the continued risk of
afternoon and evening showers isolated thunderstorms in the
cascades. Smr

Long term Friday through Monday The ridge weakens some in the
long term as an upper level trough remains camped out over the sw
us. Models remain in disagreement as to what this would spell for w
wa... As the GFS keeps conditions dry into next week while the ecmwf
hints at a couple of instances of showers late Friday and again
Sunday. Despite these details... The most recent solutions for both
models are drier than those previous. As such... Have opted to cut
back on inherited pops some. Temperatures during this time frame
look to remain fairly stable... With highs in the interior lowlands
not getting warmer than the lower 70s... And even dropping back into
the 60s toward the end of the forecast period. Smr

Aviation Northeasterly flow aloft with upper level ridge
centered over central british columbia and an upper level low
well southeast of the area. Light flow in the lower levels
becoming onshore this afternoon with the onshore flow
strengthening late this afternoon and evening.

Low clouds, ceilings below 1000 feet, confined to the coast this
morning. Mid level deck moving through the area during the day.

Some patchy fog in the interior until 16z.

Ksea... Just some mid level clouds at times today. Onshore push
tonight will bring stratus into the terminal early Tuesday morning
with ceilings near 1000 feet. Light and variable winds becoming
southerly 6 to 10 knots tonight. Felton

Marine Onshore flow will increase today with a moderate
onshore push expected tonight. Onshore flow will continue through
the week as high pressure remains centered well offshore with
lower pressure east of the cascades.

Gale force winds forecast for the central and eastern strait of
juan de fuca tonight with small craft advisory winds over the
southern portion of the northern inland waters. For the remainder
of the week small craft advisory west winds possible in the
central and eastern strait of juan de fuca each evening through
Friday. Felton

Hydrology The daily hydrology discussion has ended until the
start of the next rainy season; it will only be updated as needed
until then.

Sew watches warnings advisories
Wa... None.

Pz... Gale warning from 6 pm this evening to 5 am pdt Tuesday for
central u.S. Waters strait of juan de fuca-east entrance
u.S. Waters strait of juan de fuca.

Small craft advisory from 6 pm this evening to 5 am pdt Tuesday

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.
