Synopsis for the northern and central washington coastal and inland waters..High pressure over the pacific will build east tonight and Saturday. This will increase an easterly offshore flow tonight and this weekend. Initially strong, the winds will weaken by early Saturday and remain offshore this weekend. The weather will be quiet for several days with the high pressure and no marine weather concerns. By mid-week, potentially the next system with impact for the region will begin to push in from the west.

Synopsis Drying and clearing from the north today as a weak
weather system exits to the southeast today. Saturday through
Tuesday will be dry, with patchy night and morning fog and cool
overnight temperatures. A weather system will bring wet weather back
by mid to late next week.

Short term Light rain showers have tapered off this
morning with a few lingering showers mainly over the central and
south washington coast. Conditions will continue to dry through the
morning with clearing from the north this afternoon and tonight.

Highs today will be in the low to mid 50s.

Clearing tonight will help low temperatures dip into the 30s, with
near freezing temperatures in the far north. Patchy morning fog with
some freezing fog Saturday will burn off to sunny skies and
temperatures in the low 50s. Morning fog will return again Sunday
with clearing and slightly warmer high temperatures, especially
through the eastern interior lowlands. Clear skies Sunday night will
help lows dip again into the 30s near marine and urban areas, and
into the 20s in outlying areas.

Long term From previous discussion... A sharp upper level ridge
will continue to influence our weather Monday and Tuesday, keeping
conditions dry. Monday will be mostly sunny while a weak weather
system tries and fails to make much headway against the ridge. There
is a chance of rain in the offshore waters. On Tuesday, clouds will
increase across washington, and the chance of rain will spread to
the coast. Highs both days will remain in the low to mid 50s.

The GFS and euro are now in rough agreement that a weather system
will impact the area on Wednesday, and conditions will remain
relatively wet on Thursday. Have increased pops to likely or better
both Wednesday and Thursday. Highs will be in the low 50s. Burke

Aviation Low clouds, along with spotty light rain showers,
and reduced visibility are observed across the area this morning.

Most terminals are ifr or lower at this point with some visby at
1 4sm or less in spots. A mid level trough axis is diving south
across the area and will exit throughout the day as a high pressure
from the pacific builds in. This will gradually bring improvement,
but this morning should feature several more hours of reduced
ceilings and visibility before improvement 18-21z.

Clear skies tonight may lead to localized areas of fog. Winds will
remain southerly ahead of the front, with a northerly component to
the winds in its wake. Wind speeds will generally be 5-10 knots.

Ksea... Winds have shifted northerly 6-8kts and will remain there
through the day. Occasional visibility less than 1 mile and ceilings
at 200 ft or less have been observed this morning and the
possibility for these bad conditions will prevail through about 18z
or so before slow clearing and improvement brings conditions to
better than ifr. Skies will clear after 21z and there may be some
patchy fog late overnight tonight into early Saturday morning.

Johnson

Marine A trough of low pressure will exit through the area today
and give way to a ridge of high pressure building east from over the
pacific. This will produce some small craft advisory level winds
through early Saturday morning before improving conditions as the
ridge of high pressure takes over. Strongest winds today should
remain in the northern inland waters and then expanding through the
strait and northern offshore waters tonight. Johnson
hydrology... Models are indicating a rainy period to start up midweek
through the end of next week. This would drive rivers up sharply.

But so far, no river flooding looks likely through the next seven
days.

Sew watches warnings advisories
Wa... None.

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.
