Synopsis Scattered showers will decrease overnight. An upper
level ridge will give dry conditions to the area Saturday through
Sunday. The next front will give some rain to the area later Monday
through Tuesday with showers possibly persisting into Wednesday. Dry
weather is expected to return Thursday and Friday of next week.

Short term tonight through Monday Scattered showers will
decrease overnight and upper ridging will give dry conditions to
the area Saturday through Sunday. Low level onshore over the
weekend will probably make for night and morning clouds and temps
will be average. The global models show the next front
approaching on Monday with rain developing by Monday night.

Long term Tuesday through Friday Models are generally in good
agreement that the best chances for rain across the area will be
Tuesday as a frontal system passes. Post frontal showers Tuesday
night will decrease or come to an end on Wednesday. Zonal flow
with dry conditions and low level onshore flow is expected to
prevail later next Wednesday or Wednesday night through the end of
the week. Temperatures will be seasonal.

Aviation Scattered showers will taper off overnight. This evening
the lowest clouds are being reported near the olympics, while
conditions have improved up and down the i-5 corridor--with some
clearing north of seattle. There is still the last gasp of a
frontal band hung up over southwest washington and about the south
half of the cascades, but that will finally shift east overnight.

It is pretty likely that there will be areas of morning clouds and
then some afternoon sunshine on Saturday.

Ksea... The rain is ending this evening as a frontal band slowly
shifts east, a few showers might linger overnight. Morning clouds
should give way to afternoon sunshine on Saturday.

Marine Western flow in the strait has been a bit weak so far, but
we may yet see a few hours of small craft westerlies this evening.

The flow will remain onshore through this weekend due to high
pressure over the NE pacific. A frontal system will reach the area
Monday then weaken and move inland Monday night and Tuesday.

Hydrology With the rain diminishing and exiting the area,
rivers coming out of the north half of the wa cascades have crested
while rivers coming off of the southern half of the wa cascades
continue rising and will be cresting overnight but are expected to
remain well below flood stage. Going forward, river flooding is not
expected across the area for the next 7 days.

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.
