Synopsis An upper ridge will bring dry and warmer weather
through memorial day. Onshore flow will develop Monday night or
Tuesday giving a cooling trend and a chance of showers by the
middle of next week.

Short term Radars and satellite imagery shows thunderstorms
over northern portions of eastern washington with a few showers
and isolated thunderstorms extending as far west as just east of
sumas in whatcom county, index in snohomish county, and mount
rainier national park. Cumulus clouds from the southern olympic
mountains southward into eastern grays harbor and western lewis
counties have not developed. This convection will dissipate early
this evening as the short wave trough initiating the development
moves off to the southeast and we lose our sunshine.

A 575+ dam 500-mb ridge along 138w and its 1029 mb high centered
near 49n 143w will slide slowly eastward tonight through Saturday.

By Saturday the upper ridge will be centered over western
washington with heights around 580 dam. The main surface high will
remain centered offshore, but even with the light onshore flow,
warm air aloft and plenty of sunshine will allow temperatures to
rise into the lower 80s from about seattle southward. Sunday looks
2-4 degrees warmer than Saturday across the area as weak thermal
troughing extends from the olympics southeastward to the columbia
river gorge area. When will the next marine push occur? The 18z
gfs and its ensembles hint at during the day Monday as the ridge
shifts east and an upper trough approaches from the west. The 12z
ecmwf and canadian solutions along with their ensemble means
suggest a day or so later. Monday, and Tuesday could remain quite
warm if the later solutions verify.

Forecasts look good for now. No evening update is needed. Albrecht

Long term From the previous long term discussion: an upper
ridge over the area will shift inland early next week. This will
put western washington in unstable southerly flow aloft on the
back side of the ridge. There could be some afternoon and evening
thunderstorms over the cascades Monday and Tuesday in this
pattern. There will also be a chance of showers for the lowlands
by Tuesday.

The other change early next week will be for cooler weather.

Cooling will probably be mainly confined to the coast on Monday
then the interior will cool several degrees on Tuesday. It should
be noted that the latest ECMWF is slower pushing the upper ridge
inland. If the ec is correct, Tuesday would be another warm day
for the interior and the onshore push would be on Wednesday.

An upper trough will settle over the area Wednesday and Thursday
for a good chance of showers. Highs should cool to near normal.

Schneider

Aviation High pres aloft will continue to build into the area
from the west overnight. Strong nly flow aloft will weaken. Contd
weak low level onshore flow. The air mass over the cascades will
cont stabilizing this evening. The threat of tstms has ended.

Meanwhile, anticipate areas of ifr CIGS vsbys to dvlp over the
coast overnight. Patchy lifr CIGS and vsbys (due to fog) are
possible from about kolm swd after 0900 utc.

Ksea...VFR. Winds will generally be light nly.

Marine High pressure centered over the northeast pacific with
lower pressure inland will result in light onshore flow (flow from
off the pacific) through Friday. The flow will become more
northerly this weekend due to the offshore high weakening and
redeveloping off the ca coast.

Sew watches warnings advisories
Wa... None.

Pz... Small craft advisory until midnight pdt tonight for central u.S.

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.
