Synopsis A strong warm front, fed by a plume of warm
subtropical moisture will bring heavy rain to western washington
today and tonight, with the snow level rising to near 8000 feet.

After a relative break in the weather on Wednesday, another wet
frontal system will move through the region Wednesday night and
thanksgiving. There will be another break on Friday, followed by
more wet weather this weekend and into Monday.

Short term Radar has been lit up this morning by rain from the
incoming warm front. Strong SW flow aloft has created a tiny rain
shadow NE of the olympics around port townsend. IR imagery shows
the tap into subtropical moisture E of hawaii. The heaviest rain
is still expected late this morning through this afternoon.

Precipitation is expected to diminish, but not end, this evening
as a slight shift in the flow aloft directs the weakening moist
plume over oregon. The subtropical air mass will push snow levels
up to around 8000 feet this afternoon and remain near that level
tonight. Models have been fairly consistent with regard to
precipitation amounts; storm totals for today and tonight should
be roughly 2 to 5.5 inches over the olympics and mount rainier,
with 1 to 4 inches over the cascades north of mount rainier.

Warm moist southwest flow aloft will continue Wednesday, as
an upper trough digs into our far offshore waters outside of 135w.

There will be more rain on Wednesday, especially at the coast and
over the mountains, but it will be a relative break in the action.

Precipitation in the mountains will amount to another half inch to
inch, with the snow level still near 8000 feet. The warm air mass
will push temperatures up to around 10 degrees above normal on
Wednesday, with highs near 60.

The next frontal system will develop offshore on Wednesday, ahead
of the upper trough, and progress across western washington
Wednesday night and thanksgiving. The snow level will be around
7000 feet as the event starts, then lower to around 4000 feet
behind the front as precipitation decreases Thursday night. This
system doesn't look quite as wet, but it should bring another 1.5
to 3.5 inches of precipitation to the mountains with the heaviest
amounts over the olympics. Mcdonnal kam

Long term Previous discussion from the 325 am afd... The models
agree fairly well on the big picture in the long term period,
Friday through Monday. They show a short- lived, relative break in
the weather on Friday, then two frontal systems in quick
succession on Saturday and Sunday, followed by cooler moist
westerly flow on Monday. Confidence in model details isn't very
high, but I will increase pops somewhat for Saturday through
Sunday night. Mcdonnal

Aviation Strong southwest flow aloft will continue today and
tonight. A warm front will move across the area from south to north
today. Rain today, tapering tonight. The air mass will be stable
through tonight. At the surface, strong easterly gradients will ease
tonight and become more southeasterly. Llws is possible at most
terminals today.

Conditions are generally MVFR today with pockets of ifr. Low end
MVFR conditions will continue behind the warm front tonight, but
rainfall rates and low level wind shear will decrease from the
south.

Ksea... Discussion above applies. Northeast or east winds 4-8 kt will
become southeast 8-12 kt after 00z. Chb

Marine A warm front will move south to north across the area
today. Strong offshore flow will give gales to the coast and west
entrance, with small craft advisory conditions elsewhere.

Another frontal system west of the waters will give strong southerly
flow Wednesday and Wednesday night. Windy southerly flow will
continue on Thursday as a trough brushes the area. Gales are
possible with this system.

Latest model solutions show a developing low offshore moving by to
the west of the waters on Saturday. This will give windy
conditions to the area on Saturday. Chb

Hydrology A warm front and the plume of subtropical moisture
with it will bring 2 to 5.5 inches of rain to the olympics and
mount rainier today and tonight, and 1 to 4 inches of rain to the
cascades north of mount rainier. The snow level will be near 8000
feet. A second frontal system will bring another 1 to 4 inches on
Wednesday night and Thursday, with the snow level falling from
7000 feet to 4000 feet as the system moves through.

A flood watch is in effect for most of the forecast area. The
skokomish river, which only fell below flood stage Monday
evening, will almost certainly flood again late today or tonight.

In addition the northwest river forecast center models show
several rivers cresting near or just above flood stage including
the cowlitz, nisqually, white, snoqualmie, stillaguamish, skagit,
and nooksack. This doesn't mean the possibility of flooding is
limited to these rivers. Flooding on these rivers could begin
tonight or Wednesday. It looks like the threat is for a relatively
minor flooding episode.

In addition, the threat of landslides will increase across the
lowlands of western washington. The USGS landslide guidance shows
one or two stations near or just above the threshold of concern,
and of course the additional rain today and tonight and again
Wednesday and Thursday will drive that higher. Mcdonnal

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.
