Synopsis Showers will taper today and tonight. A front will cross
western washington Tuesday night and Wednesday, bringing more rain
to the lowlands and possibly heavy snow to the mountains. A cool and
showery upper trough will reach the area Thursday. The air mass
Thursday night and Friday morning could be cold enough for a little
lowland snow. Warmer and wetter conditions are likely next weekend.

Short term An upper trough over the area will bring widespread
showers this morning, along with isolated thunderstorms on the coast
and snow in the mountains. Showers will taper this afternoon and
snow will mostly end in the mountains. The afternoon and evening
should bring a brief break in the rain and shower activity, and the
sun might even peek out briefly. Highs will be in the 40s.

The next system will reach the coast Tuesday morning and spread
inland during the day. Another 24 hours or so of rain in the
lowlands and snow in the mountains is likely. The snow level will be
near the pass level and current forecasts call for heavy snow,
especially during the period 18z Tuesday to 06z Wednesday. Highs
both Tuesday and Wednesday will be in the 40s. Burke

Long term Conditions will turn more showery Thursday as an upper
level trough moves into the region. This trough will be colder than
recent ones, with heights in the 530s. The snow level Thursday night
will fall to below 1000 feet in some areas, and overnight low
temperatures will be in the low to mid 30s. The upshot is there
could be a little lowland snow by Friday morning. Showers will
taper considerably later Friday and warm advection should melt any
snow on the ground.

The latest run of the GFS has periods of heavy rain over the
weekend, though not as much as in some previous runs. The euro is
similar. High pops with high temperatures in the 50s seem likely
Saturday and Sunday. Burke

Hydrology The skokomish river in mason county crested last
evening and will fall below flood stage this morning. More rain
Tuesday night could bring the skokomish back above flood stage for
another round of minor flooding.

Recent rainfall has brought the USGS landslide indices closer to
thresholds for shallow landslides, but they have not yet exceeded
those thresholds.

Flooding is unlikely on rivers other than the skokomish through
Friday. Some models show heavy rain in the olympics and cascades
next weekend from a strong warm front. This rain, if it occurs,
could be heavy enough for more widespread flooding. Burke

Aviation A trough of low pressure will produce showers over the
area early this morning as it moves eastward. Showers will
increasingly become tied to the terrain between systems later this
morning through this evening. A strong warm front will approach
the area from the west late tonight and reach the washington
coastline late Tuesday morning. Flow aloft will be westerly as a
flat upper level ridge moves across the area. The air mass will be
moist through Tuesday. The air mass will be somewhat unstable
this morning and will stabilize this afternoon and tonight.

Numerous showers are moving northeastward across the region this
morning as a trough of low pressure at the surface and aloft moves
across western washington. Conditions are generally on the low end
ofVFR, except MVFR in heavier showers. Expect conditions to
gradually improve between 18z and 20z as the trough moves off to
the east. Ceilings in the interior and along the immediate coast
will be held up in theVFR category tonight as low level easterly
pressure gradients increase in advance of the incoming frontal
system. Albrecht
ksea... Showers will give low endVFR to MVFR ceilings through this
morning. Expect improvement toVFR this afternoon through tonight.

South winds 7-10 knots will gradually turn southeasterly 5-8 knots
this evening. Albrecht

Marine Moderate southerly onshore flow early this morning will
gradually ease through this evening as a trough of low pressure
moving across the waters shifts east of the area. Small craft
advisories remain in effect for winds or seas along the coast and
at the west entrance to the strait through this evening, while
residual small craft advisory conditions continue over portions of
the puget sound early this morning.

A strong frontal system will move into the coastal waters Tuesday
morning then will push inland Tuesday afternoon. Expect gales over
the coastal waters and at the west entrance to the strait ahead of
this front late tonight into Tuesday. Gales are possible at the
east entrance to the strait late Tuesday morning into Tuesday
afternoon. Gale warnings have been issued for the coast and west
entrance, and a gale watch is in effect for the eastern portions
of the strait on Tuesday.

Latest forecast models show a couple of small, but vigorous lows
rotating around an upper level low in the gulf of alaska and into
vancouver island on Wednesday and Wednesday night. Gales are
possible with these features, and seas in excess of 20 feet
developing on the south side of these lows will likely affect the
waters on Thursday.

Yet another in a series of strong systems will affect the waters
later Friday or Friday night into next weekend. Albrecht

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
