Synopsis Onshore flow into Monday as a weak weather system
passes to the north of western washington. An upper level ridge
will strengthen early next week for warmer temperatures and more
sun. A front is expected around the middle of the week with a
chance for showers and cooler temperatures.

Short term today through Tuesday Satellite imagery shows
stratus clouds across much of western washington this morning with
low level onshore flow. More sunshine is expected this afternoon
with generally weaker onshore flow and a marine layer that is a
bit less organized as a system slides to the north of the area.

Temperatures this afternoon will be in the upper 60s to mid 70s
across the area.

Dry weather through Tuesday with an upper level ridge building
across the area Monday afternoon. Low level flow will become light
or even weakly offshore by Tuesday. Clouds will begin to increase
Tuesday afternoon ahead of the next system. Higher heights with
additional sunshine will boost temperatures into the 70s for
Monday with 80s in most places across the interior Tuesday
afternoon. Jd

Long term Wednesday through Saturday A trailing cold front
associated with the upper trough offshore will move onshore on
Wednesday. The models haven't been very consistent with its
strength, but it does seem like the coast and olympic peninsula
will get some decent QPF out of it. How much is left by the time
the weakening front reaches the interior is still in question.

Plenty of cloud cover and cooler temperatures are a good bet for
Wednesday.

The front looks to dissipate in the cascades Wednesday night with
zonal flow and drier conditions expected for Thursday. The mean
trough position remains in place to our northwest as we approach
the weekend with another system possibly clipping the northwest
corner of the state Friday night or Saturday. 27

Aviation Low level onshore flow will becoming light on Monday.

Westerly flow aloft.

Like the previous two mornings... W wa is once again socked in with
low level clouds over much of the area. Unlike the past two mornings
though... Current satellite trends are hinting at some possible
thinning over the puget sound area... Including ksea. While
improvement seems minimal on satellite loop... Current obs from ksea
and kbfi seem to support this with reports of few to sct clouds. For
the remainder of the area there has not be much improvement yet with
cigs generally still MVFR. Continue to expect CIGS to lift gradually
through the morning with widespreadVFR conditions expected this
afternoon... With the potential for some clearing this evening and
tonight before stratus returns early Monday morning and bringing
conditions back into MVFR range.

Ksea... As stated above... Conditions improving over the terminal but
still the prospect for bkn low level clouds through the remainder of
the morning. CIGS still expected to lift back up to the 4500-6000
foot level this afternoon before scattering this evening and tonight
before stratus returns early Monday morning. Winds south southwest 4
to 8 knots. Smr

Marine Low level onshore flow through tonight will
becoming light Monday and Tuesday. Small craft advisory westerlies
expected in the central and eastern strait of juan de fuca tonight.

Given the brief period of SCA winds in the strait Saturday
night... Will leave inherited headline alone for the morning forecast
package. A front will move through the waters on Wednesday with
small craft advisory southerlies over the coastal waters. High
pressure will build over the coastal waters behind the front
Thursday. Smr 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.

Wa... None.

Pz... Small craft advisory from 6 pm this evening to 2 am pdt Monday

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.
