221 am pst Wed jan 23 2019

Synopsis Showers will diminish across the area today behind a
departing frontal system. High pressure aloft will bring drier
weather to the region Thursday into early next week. A couple of
very weak weather systems will bring a chance of showers to mainly
the coast and northern cascades Thursday night and again on
Sunday.

Short term today through Friday The front that brought a few
hours of moderate to locally heavy precipitation to the region is
now well east of the cascades this morning with the trailing upper
trough now crossing the area. This will keep some shower activity
going this morning, but it will diminish as the day progresses. By
evening, any remaining showers will likely be confined to the
cascades. Despite persistent cloud cover, daytime temperatures
will be remain a little above seasonal normals.

A dirty upper ridge will begin to build into the region tonight.

Light surface gradients and considerable low level moisture spell
a rather grey but reasonably dry day for western washington on
Thursday. A weak weather system passing over the top of the
building ridge offshore looks to bring a chance of a shower to
coastal areas and the cascades Thursday night. After that, the
ridge continues to gain some amplitude on Friday. There will still
be a lot of low level moisture around on Friday, but there could
be a few peeks of Sun late in the day. High temperatures in the
lowlands on both Thursday and Friday will be near 50 with lows
generally mid 30s to lower 40s. 27

Long term Saturday through Tuesday Models remain in good
agreement with the idea of the upper ridge axis shifting onshore
and flattening somewhat on Saturday in response to a weather
system moving into british columbia. This same weather system
retrogrades the ridge offshore and clips the northern part of the
forecast area. At this point, the best chance of any precipitation
appears to be in the north cascades with dry conditions for the
remainder of the region. By early next week, the upper ridge axis
shifts offshore with strong surface ridging taken up residence in
the interior of british columbia. This looks like the set up for
more dry weather, but lowering temperatures as some colder air
filters out of the fraser river valley. 27

Aviation Strong, post-frontal onshore flow will continue this
morning for showers and gusty south winds. The flow aloft is nw. Most
terminals are within ifr to MVFR range. Showers will taper down
this afternoon and evening as onshore flow weakens and a ridge
nudges inland. However, the low level air mass will remain moist
for MVFR to low-endVFR conditions. 33
ksea... Showers in the vicinity this morning with gusty S winds to
25 kt. Winds easing this afternoon and showers tapering off.

Moist low level air mass will keep CIGS mainly in MVFR range. 33

Marine A weakening low on the central coast of vancouver island
early this morning will move ese through the northern inland
waters this morning. Small craft advisory conditions are occurring
over the waters this morning, and winds will gradually diminish
this afternoon. Small craft advisories will continue into tonight
for the coastal waters and at the western entrance to the strait
as seas remain hazardous and only slowly subside through tonight.

Weak high pressure will build into the waters this afternoon
through Thursday and will remain over the waters through Saturday.

Expect light winds with seas over the coastal waters continuing to
slowly subside. Offshore flow may increase on Sunday as high
pressure builds into the interior of british columbia.

Coastal flood advisories remain in effect for the shorelines
along the inland waters from point roberts to the south end of
puget sound and hood canal around the morning high tide. Tides are
near the highest values for the year and will be accompanied by
relatively low pressure and lingering longer-period anomalies.

Some waves early this morning, especially along southwest facing
shorelines from seattle southward and northwest facing shorelines
on the san juans and in western whatcom county may crash into
seawalls during the high tide. Any salt-water flooding that
occurs this morning is expected to be brief and minor with tides
topping out 0.2 to 0.5 feet above the value where minor flooding
begins. Albrecht

Hydrology Heavy rain has ended in the olympic mountains but the
skokomish river in mason county continues to rise. The current
forecast has the river cresting near minor flood stage this
morning and the flood watch remains in effect. The river will
recede this afternoon and evening. Otherwise, river flooding is
not anticipated over the next 7 days.

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.
