215 pm pdt Wed may 22 2019

Synopsis The weather will be dry into Thursday except for a
chance of afternoon and evening showers and thunderstorms over the
mountains. An upper low will bring a chance of showers to the area
on Friday and another upper low might drop down over the area on
Saturday. Weak high pressure will be in place early next week.

Short term tonight through Saturday There is stratus along the
coast afternoon and that will move inland a bit overnight and fill
in over southwest wa. Thursday looks like a pretty nice day again
after some areas of morning clouds burn off. Once again, there will
be a chance of a few showers in the cascades for the afternoon and
evening hours--and maybe a thunderstorm near the cascade crest.

Highs will warm up a bit more into Thursday. For Friday and Saturday
showers return to the forecast as upper troughs drop down through
the area. The ECMWF shows a chance for some wet weather Saturday
afternoon and evening around the puget sound area but the GFS is
weaker and just shows some scattered shower activity. High temps
Friday and Saturday will be cool with highs in the lower to mid 60s.

Long term Sunday through Wednesday The weather pattern next
week looks unremarkable--we will probably areas of morning low
clouds but otherwise there is a good chance for sunny days with
temps a bit above normal. Highs should range from the 60s on the
coast with lower to mid 70s for the interior of western washington.

Aviation Northerly flow aloft will continue tonight and
Thursday with an upper ridge offshore and an upper low over the
intermountain west. At the surface, onshore flow will continue
with high pressure offshore and lower pressure inland. The air
mass is generally stable except unstable over the cascades through
this evening.

Areas of mid level clouds from puget sound eastward should
decrease tonight. Low clouds near the coast the will spread
partially inland tonight then burn back to the coast later
Thursday.

Ksea... Areas of mid level clouds should decrease tonight. Low
clouds at the coast will spread inland tonight and probably reach
the terminal for a few hours Thursday morning. Northwest to north
wind 5-10 knots will becoming light tonight then west to
northwest Thursday afternoon. Schneider

Marine Onshore flow will increase on Thursday then gradually
decrease Friday and Saturday. Small craft advisory strength west
winds are likely each evening for the central and east entrance
strait of juan de fuca. Onshore flow will peak Thursday evening
when gale force west winds are possible in the strait and small
craft advisory westerly winds will bleed into the adjacent inland
waters.

There will be a brief period of offshore flow Saturday night and
Sunday with a thermal trough along the coast. Onshore flow will
increase again on Monday.

In addition, strong high pressure well offshore will bring small
craft advisory strength northwest winds to the coastal waters for
the next few days - initially over the offshore waters but
eventually spreading into the inner waters around Thursday night.

There will also be 10-14 foot west to northwest swell over the
coastal waters, highest farther offshore. Schneider

start of the next rainy season; it will only be updated as needed

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.
