Synopsis Areas of fog and low clouds kept the coast cool today.

The low clouds and fog will fill in over most of the lowlands Friday
and Saturday mornings. Sunday and Monday will probably see a bit
less of the morning fog and low clouds. The weather will stay dry
through Monday--and the afternoons will probably remain sunny.

A front will arrive Tuesday, with additional fronts to follow after
the middle of next week.

Short term An upper ridge will remain over the pacific nw
into the weekend--although for now it has flattened and some
mid and high clouds came through the area today. More cirrus
should arrive tonight. Also, there are low clouds and fog on the
coast--where it was much cooler today. For Friday and Saturday
there will be widespread areas of night and morning fog and low
clouds that should clear out for mostly sunny afternoons. That
part of the forecast could very well be wrong, but looking at the uw
wrfgfs lowest level cloud product--the clouds seem to break out okay
each day, and the morning low clouds and fog become less extensive
on Sunday. Obviously there is a chance that there will be pockets of
low clouds and fog that do not clear out til later in the afternoon
or not at all (after all, the coast hadn't cleared out today as of
2pm). I did knock down the high temp forecast on Friday--but there
can be a big difference between an 11am and a 2pm burnoff. I suspect
after being too cool the past couple of days, the forecast may very
well be several degrees too warm now--it was 55 degrees at forks at
2pm today, yesterday highs were in the 70s out there.

Long term Dry weather will continue Monday but the upper
ridge over the area will be inland and fading fast. Periods of wet
weather begin Tuesday as several frontal systems make landfall
through the end of next week.

Aviation Upper level high pressure will remain in control with
light onshore flow. Scattered high clouds inland through this
evening while stratus fog remains along the coast. Shallow patchy
fog possible Friday morning with visibilities reduced to a mile
or less where it does develop. Should quickly burn off during the
morning hours after sunrise.

Ksea... A few high clouds this evening with light winds. Patchy
fog development after 12z Friday morning which could drop
cigs visibility to ifr lifr. Improvement expected after around 19z
Friday. Ceo

Marine Light onshore flow pattern will continue through the
weekend. An approaching front on Monday will turn the low level
flow southeasterly with small craft advisory winds possible over
the outer coastal waters late Monday into Tuesday. Ceo

Sew watches warnings advisories
Wa... None.

Pz... None.

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.
