Synopsis Persistent surface high pressure over the NE pacific
combined with low pressure east of the cascades will maintain onshore
winds the next several days. Slight variations of the upper level
pressure pattern will result in slight variations in how expansive
nighttime morning clouds will be through early next week. The clouds
should clear in the afternoons with temperatures remaining near the
seasonal normals. An upper level ridge is expected early next week
for less clouds and slightly warmer temperatures.

Short term This afternoon through Saturday... Latest satellite
imagery shows morning stratus has spread throughout the coast, coast
range, and entire willamette valley, even spreading into the northern
oregon cascade foothills. Expect stratus to be slow to burn off,
dissipating from south to north when it does. Updated sky cover
forecast this morning to reflect latest satellite trends and push
back the clearing of skies, particularly north of about corvallis
and along the coast north of newport. Otherwise the forecast looks
great with seasonable temperatures and mainly sunny skies later this
afternoon. Bowen
there will be little change in the weather tonight and Friday
as another upper level trough passes by to the north and low-level
onshore winds persist. The marine layer should deepen late Friday
night and early Saturday morning as an upper level trough develops
over NW oregon for a better chance for more widespread clouds
Saturday morning. Therefore the temperatures Saturday afternoon will
be slightly cooler. Mh ~tj

Long term Saturday night through Wednesday. Overall, rather benign
pattern with varying degrees of onshore flow for the weekend. Weak
system will pass to over region on Saturday, but seems system is
splitting. This will keep local mostly dry, with threat of any
showers staying well north over british columbia. But this system
will allow for increased onshore flow, with some spotty drizzle along
the the coast. Mainly, expect more in way of clouds around region for
sat, and again later Sat night into sun.

Now, for the big question: what about Monday? At this time, looks
like will slip back into the pattern we have had the past few days.

This will keep threat of late night and morning clouds along the
coast, mainly to north of newport. However, confidence is only at
about 50% for the area of eclipse totality along the coast Monday
morning. Models are showing small but significant differences in
surface winds, which could mean the difference between overcast skies
and clear skies at the coast. The interior looks to remain clear on
Monday, though cannot rule out a few clouds along and to
north of the columbia river prior to 10 am (outside of the eclipse
totality). Temperatures stay near seasonable.

But changes appear in store for the region for Tue and beyond. Upper
low off calif coast will start drifting northward, bringing a return
to southerly flow over the region. This will allow for increasing
threat of afternoon evening thunderstorms over the oregon cascades.

Temperatures still near seasonable levels. Bowen rockey

Aviation Moderate onshore flow this am, with widespread MVFR
stratus across the region. Tops generally 3500 to 4000 ft, so
expect most of the inland stratus to break between 18z and 20z.

But coastal stratus will hold bit longer, with last to scattered
being that around and north of astoria.

Marine stratus will spread back along the coast tonight, and into
the interior later tonight. But with bit less onshore flow, will
not be as extensive inland or as far south as was today.

Kpdx and approaches... MVFR stratus now, with clouds gradually
breaking after 18z. Likely notVFR til 19z or 20z. Will see MVFR
stratus return late tonight into Fri am. rockey.

Marine High pres will remain over the coastal waters through
early next week, with thermal low pres over northwest california
and southwest oregon. This will keep our summer-time northerlies
in place, with breezy winds developing in the afternoon evening
hours for the next several days, especially south of newport. A
sca for winds remains in effect from this afternoon through early
Friday, with additional advisories likely this weekend.

Seas will generally be around 5 to 7 ft through the period, but
may build to around 8 ft at times as the winds increase. Seas may
also become steep at times during the afternoon evening hours.

Pqr watches warnings advisories
Or... None.

Wa... None.

Pz... Small craft advisory for winds for this afternoon through
tonight on coastal waters from cascade head to florence.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
