Synopsis The weather will be dry today and Thursday except for
afternoon and evening showers and thunderstorms over the mountains.

An upper low will bring a chance of showers to the area for the end
of the week. Weak high pressure will be in place by early next week.

Short term today through Friday It will be mostly sunny days
today and Thursday in the lowlands. Afternoon and evening showers
will build up over the mountains, and there might be a thunderstorm
or two. Highs will warm through Thursday--with the warmest areas up
around 77 on Thursday. An upper trough will drop over the area
Friday and shift into oregon on Saturday for some shower activity
and cooler temps.

Long term Saturday through Tuesday Showers should mainly
just be over the cascades on Saturday and high pressure builds back
over the region Sunday and Monday. The weather pattern next week
looks unremarkable for western washington--maybe we will get into a
regime of areas of morning clouds otherwise sunny days for a few
days.

Aviation Northwest flow aloft will continue with an upper ridge
offshore and an upper trough inland. At the surface, onshore flow
will prevail with high pressure offshore and lower pressure
inland. The air mass is somewhat moist and stable, except
becoming unstable over the cascades this afternoon and evening.

Areas of low clouds, mostly southwest interior, will burn off
today. Otherwise, mid level clouds will be around today and
tonight. Some low clouds are likely again Thursday morning but
they look more patchy compared to this morning.

Ksea... Mid level clouds today and tonight. Light south wind this
morning will become north to northwest 5-10 knots this afternoon
then light again tonight. Schneider

Marine Onshore flow will prevail for the next couple of days
with high pressure offshore and lower pressure. Onshore flow will
ease Friday and Saturday and turn offshore on Sunday as a thermal
trough develops along the coast.

There will be small craft advisory strength northwest winds over
the outer coastal waters through Friday night with gales possible
on Friday. The small craft advisory strength northwest winds will
expand into the inner coastal waters Thursday night and Friday.

There will be small craft advisory strength west winds in the
central and east entrance to the strait of juan de fuca the next
couple of evenings. The strongest westerlies will be Thursday
evening when it might briefly hit gale in the strait.

There will also be 10+ feet west to northwest swell over the
coastal waters the next few days, mostly over the outer coastal
waters. Schneider

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.
