240 pm pdt Sun mar 26 2017

Synopsis A front will move inland this evening with rain
turning to scattered showers. A trough will keep showers in
the forecast Monday. A warm front will reach the area Tuesday
for more rain. A vigorous low pressure system and front will
move through the area on Wednesday. A trough will keep showers
in the forecast Thursday. Dry weather is expected Friday.

Short term Rain from a front will break up to showers tonight
and the showers should become more scattered on Monday. The winter
weather advisory for portions of the cascades has been cancelled,
snowfall tonight will be between 2 and 5 inches above the snow
level, unremarkable. Tuesday will see a warm front arrive and that
system fizzles out over the area Tuesday evening. Another frontal
wave, this time a stronger system, will move through western
washington on Wednesday. The 12z GFS took a deepening 999mb low
into vancouver island midday, with a decent southerly gradient
giving windy conditions over the area.

Long term The push of onshore blustery weather behind the system
on Wednesday will settle down Wednesday night and Thursday. An upper
trough moves inland and surface high pressure builds across
the region. An upper ridge will be in place Friday for a dry day
with some sunshine. Clouds will likely increase Friday night with
a chance of rain by Saturday as a warm front pushes into the ridge.

Aviation An upper level trough off the coast is forecast to move
onshore into western washington Monday. SW flow aloft over
washington tonight becoming NW behind the trough. At the surface, a
frontal system was moving onshore this afternoon and will continue
inland this evening. Onshore flow behind the front. Air mass
becoming somewhat unstable behind the front for showers into Monday.

MVFR ceilings in the vicinity of the front. Showers with a mix of
breaks in the cloud cover tonight into Monday morning will offer a
mix of MVFR andVFR conditions. Mountains to remain obscured in
clouds and precipitation through at least Monday morning.

Ksea... The terminal is likely to have primarily upper end of MVFR
ceilings both with the front late this afternoon and evening, and
through the night into Monday morning with passing showers and cloud
cover. ImprovingVFR conditions likely Monday afternoon. Southerly
winds around 10 kt should kick in with the front and continue
through Monday morning. Buehner

Marine An occluded front was moving onshore this afternoon
and will continue inland tonight. Low level onshore flow with and in
the wake of the front. Will change the gale warnings to small craft
advisories that will only last until this evening.

A surface trough is expected to move onshore Monday with a showery
weather regime and then higher pres building behind it Monday night.

The next weak pacific frontal system is expected to arrive Tuesday.

A low is expected to develop and intensify as it tracks from well
off CAPE blanco northeast into central vancouver island Wednesday
with potential gale force winds at least for the coast. The
associated cold front to move onshore late Wednesday with moderate
onshore flow. Higher pres to build onshore Thursday into Friday.

Buehner

Hydrology River flooding is not expected for the next 7 days
with the exception of possibly the flood prone skokomish river in
mason county, where heavier rain in the olympics Tuesday night
and Wednesday could be enough to get the river above flood stage
Wednesday.

Sew watches/warnings/advisories
Wa... None.

Pz... Small craft advisory near shore coast, strait of juan de fuca,
northern inland waters and admiralty inlet until this evening.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
