Synopsis A series of weather systems will move through western
washington into the first half of next week. A brief break in the
action is possible Wednesday and Thursday as a ridge begins to
build offshore.

Short term tonight through Monday Radar as of 2pm shows
scattered showers across western washington this afternoon with an
olympic rain shadow effect over portions of northern king county
and snohomish county with westerly flow aloft. A few lightning
strikes have been recorded through today, generally over the
coastal waters. Any thunderstorm activity should be over the coast
through this afternoon into early tonight as an upper level
trough approaches.

A heavier batch of precipitation will slide through tonight,
especially across the southern portions of the CWA generally south
of king county, as the upper level trough moves through. Snow
levels will fall near 4000 feet by Saturday morning. Winter storm
warning is in effect for the cascades of lewis and pierce counties
through Saturday afternoon where an additional one to two feet of
snow is possible in spots. A winter weather advisory is in effect
for the northern and central cascades of western washington where
an additional 4 to 8 inches is possible above 4000 feet. Snow
will taper off by later on Saturday.

Isolated thunderstorms will also be possible later tonight through
Saturday afternoon as the trough slides through. Best chance for
t-storms across the interior around the puget sound will be
midday Saturday through the afternoon generally south of skagit
county with sufficient instability and lifted indices. A
convergence zone may also develop over snohomish and king counties
Saturday afternoon into Saturday evening. If the pscz does form,
locally higher precipitation amounts, including snowfall over the
cascades, will be possible with convective banding. Otherwise some
sunshine may be around Saturday afternoon, though will be limited
with extensive cumulus clouds. Temperatures on Saturday will be in
the 50s across the area.

A brief break in between systems is expected Saturday night but
another system will slide through Sunday morning into the
afternoon. Snow levels will rise with this system generally above
5000 feet by the afternoon. Another system will then move through
on Monday. Temperature Sunday and Monday will be in the mid to
upper 50s across the area. Jd

Long term Tuesday through Friday An upper trough will
generally slide north of the area on Tuesday with chance of pops
around through the afternoon. Guidance does suggest an upper level
ridge builds offshore Wednesday into Thursday for drier weather.

Temperatures in the mid to upper 50s across western washington
through the end of the week. Jd

Aviation An upper level trough will approach the region
tonight. The flow aloft is westerly and the air mass is moist and
slightly unstable. Current ceilings across the region are a mixed
bag as of 245 pm and range fromVFR to MVFR ifr in areas where
heavier showers are moving through. Radar imagery currently shows
showers moving in over much of the region, with a slight rain
shadow over the central portion of the sound. A few thunderstorms
remain possible for the coastal waters and could still impact the
coastal terminals this afternoon into early this evening. Expect
showers to increase in coverage throughout the remainder of the
afternoon and evening hours, with ceilings ranging fromVFR in
rain shadowed areas to MVFR ifr in areas in the vicinity of
heavier precipitation.

Ksea... Current conditions MVFR with light rain falling at the
terminal. Could see ceilings improve again by late afternoon or
early evening as showers move off to the east, but then lower
again tonight as additional showers move through the region.

Surface wind southerly at 5 to 10 knots. Sb

Marine Small craft advisories remain in place across the
coastal waters, northern inland waters, admiralty inlet and puget
sound this afternoon as a system makes its way through the region.

The small craft for hazardous seas will continue for the coastal
waters through this evening, with seas gradually subsiding back to
10-15 feet later tonight. A small craft for rough bar will also
continue for grays harbor bar through Saturday afternoon. Have
added a small craft advisory for the strait of juan de fuca for
Saturday associated with a westerly push. Active weather will
continue into next week with additional headlines likely from time
to time. Sb

Hydrology A series of wet systems moving through the area into
early next week will cause rivers to rise. As such, the skokomish
will need to be monitored. Otherwise... River flooding is unlikely
over the next seven days.

Sew watches warnings advisories

pierce and lewis counties.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
