area forecast discussion
national weather service portland or
931 am pdt Wed jun 28 2017

Synopsis Typical summer conditions continue through the forecast
period. An upper ridge will traverse the area Thursday and Friday,
bringing less morning stratus and slightly warmer afternoon
temperatures. Otherwise, the seasonable pattern of morning clouds and
afternoon Sun continues into early next week.

Short term Today through Saturday... Morning cloud deck not quite
as deep as yesterday, and expect burn-off an hour or so earlier today
compared to yesterday (between 20-21z 1-2 pm pdt this afternoon).

No updates to the previous discussion, which follows below. Drb
the overall weather pattern is remarkably similar to this time 24
hours ago, with most sites within a few degrees of yesterday's
temperatures and surface observations reflecting a marine stratus
deck at the coast and along the the lower columbia, but not yet fully
solid through the willamette valley. Latest satellite data depicts a
solid marine push against the coast range and willapa hills, with
inland penetration along the lower columbia towards the portland
metro area as well as into the southern willamette valley around
eugene. Meanwhile, a secondary stratus layer is developing along the
cascade foothills and beginning to build back into the remaining
portions of the valley. Can't rule out a little drizzle early this
morning out of this deeper marine layer, especially along the
coast coast range. Clouds will again be a little slow to clear, but
most of the forecast area will have at least mostly sunny conditions
by the late afternoon with temperatures into the upper 70s in the
inland valleys and in the 60s along the coast.

The offshore upper ridge will move closer to the region late tonight
and into Thursday before moving across the area early Friday.

Low-level flow remains onshore, but expect a compressed marine layer
under the rising heights associated with the ridge. As a result,
expect a weaker marine push with less widespread stratus Thursday
morning. With skies clearing earlier in the day and a warming air
mass (850 mb temperatures warming to around 14 degrees c), expect
temperatures inland to reach the lower 80s in the afternoon. As the
ridge axis moves across the region Friday, even less morning cloud
cover and temperatures into the mid 80s in the valleys can be
expected. Flow aloft becomes a bit more northwesterly as the ridge
continues eastward, with a return to more widespread morning clouds
before abundant afternoon sunshine and temperatures remaining
slightly above normals. Cullen

Long term Saturday night through Tuesday... A rather typical
summertime pattern continues through the holiday weekend as westerly
flow continues through the period. A series of weak embedded impulses
will pass well north of the area at times, with the largest impact to
the local area being increased cloud cover as the marine layer
deepens. Model guidance continues to favor late Saturday and Monday
as the likely timing for this disturbances to pass closest to the
area, but still some variability among ensemble guidance. However,
guidance has trended even more towards less (if any) light rain or
drizzle, so have also guided the forecast for early next week in this
direction. Expect that most locations will remain entirely dry
through the period with temperatures holding slightly above seasonal
normals over the weekend, then trending closer to normal for the
start of next week. Cullen

Aviation Not much change from Tuesday. Tops 040-045 and bases
again 015-025. Timing of clearing inland today similar or an
hour or so earlier than Tuesday at most, while the coast should
remain mostly cloudy through the day and this evening. MVFR cigs
return inland tonight and Thu morning with best coverage in the
north and southward along the cascade foothills, with possibly
less coverage in the west side of the valley.

Kpdx and approaches... MVFR stratus will give way toVFR
conditions early to mid afternoon, then return late tonight and
by around sunrise thu. Pt

Marine Not much change in overall weather pattern, as will see
rather persistent high pres over the NE pac, and thermal low
pres staying well south over NW california. Gradients not all
that strong, so northerly winds generally staying under 20 kt,
close to 20 kt at times in the far outer waters. Winds will be
less Thursday than today, increase a little Friday, decrease
Saturday, then increase again possibly Sunday.

Wave models are running 1-2 ft below the observed values this
morning, and with short periods of only 7 or 8 seconds, leading
to choppy seas. Issued a small craft advisory for hazardous seas
for this. Will keep it in effect through this evening and let the
next shift see if we need to extend it any further, but seas
will be falling some tonight and Thursday. Seas will then remain
below small craft advisory values through the weekend. Pt

Pqr watches warnings advisories
Or... None.

Wa... None.

Pz... Small craft advisory for hazardous seas until 11 pm pdt this
evening for coastal waters from CAPE shoalwater wa to
florence or out 60 nm.

Small craft advisory for rough columbia river bar until noon
pdt today.

Small craft advisory for rough columbia river bar from 7 pm
this evening to midnight pdt tonight.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
