Synopsis An upper trough will bring showers today. Showers
will decrease Saturday as the trough shifts inland. The pattern
will remain fairly wet into the middle of next week as a series of
weather systems move through.

Short term A front is currently pushing through the area with
rain changing to showers. The air mass will be unstable enough
for a slight chance of thunderstorms this afternoon and early
evening. The volcanoes will continue to pick up some snow. A
winter weather advisory is in effect through this morning.

Showers will taper tonight and become somewhat confined to the
mountains and coast with the loss of daytime heating. The upper
trough over the area will maintain a chance of showers into
Saturday but the coverage should be less than today. Showers
should come to an end Saturday night as high pressure aloft
briefly moves over the area.

Another frontal system will bring an increasing chance of rain
Sunday. This system is somewhat split and not too impressive but
all areas should see some rain. Rain will move onto the coast in
the morning. The interior will likely be dry until afternoon when
rain will arrive. Schneider

Long term An upper trough will shift east of the area Monday
for decreasing showers but there won't really be any break in the
wet weather as warm front rain from the next frontal system will
already be moving into the area in the afternoon. The warm front
should result in a drippy Monday night. A trailing cold front will
keep rain chances high on Tuesday and Wednesday. Drier weather is
expected on Thursday as an upper ridge builds over the northeast
pacific. Schneider

Aviation Strong southwest flow aloft over western washington
early this morning will gradually ease through tonight. The front
over the western washington interior will move east of the
cascades this morning, and an upper trough will move west across
the forecast area today and tonight. The air mass will be moist
and weakly unstable.

The widespread rain has become showery during the past hour or
so, and ceilings remain mostly ovc035-050. Conditions are locally
lower, mainly along the coast, with 3-5sm -shra br bkn-ovc011
ovc030. Conditions will improve only marginally today and tonight
with bkn-ovc ceilings mainly 035-060, as an upper trough brings
scattered showers and a slight chance of thunderstorms during the
afternoon and evening.

Ksea... Wind should become south to southwest 6-12 kt during the
next few hours and continue through tonight, with gusts to 22 kt
mainly this afternoon and evening.VFR CIGS generally 035-060
through tonight. There is a 20 percent chance of a thunderstorm
in the vicinity of ksea this afternoon or evening. Mcdonnal

Marine The front is over the western washington interior early
this morning and it should move east of the cascades this morning.

Gales have ended during the last hour or so, and the gale warnings
will be allowed to expire at 3 am.

A trough will follow the front, moving into the coastal waters
today and inland tonight. It will produce small craft advisory
winds over the coastal waters into tonight, with a small craft
advisory for hazardous seas following that through Saturday. For
the inland waters, the trough will produce marginal small craft
advisory winds through this evening.

Weak high pressure will move across the region Saturday for
lighter winds. The next frontal system will move through the area
Sunday night, with another front approaching on Tuesday. Both of
these systems look relatively weak, and gales appear unlikely.

Mcdonnal

Hydrology River flooding is unlikely 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.
