area forecast discussion

853 am pdt Fri jul 28 2017

Synopsis An upper level trough over the NE pacific will maintain
onshore flow with areas of low clouds night and morning low clouds,
near the coast and locally inland through much of the
weekend. The areal extent of the low clouds will lessen each day for
slow warming through the weekend. An upper level ridge amplifies
early next week pushing inland temperatures into the 90s, and
possibly close to 100 next Wednesday.

Short term Today through Sunday... Low clouds are primarily over sw
washington early this morning with clear skies across NW oregon.

Looped satellite imagery shows that the areal extent of the low
clouds are still expanding, with some low clouds seeping into extreme
nw oregon. Some low clouds may briefly impact NE portland metro area
this morning. A sunny afternoon will lead to warming today with
afternoon temperatures peaking in the mid 80s for the willamette
valley, and the upper 80s for the central columbia river gorge and
upper hood river valley. An upper trough moves across the region
today influencing the surface pressure SE of the cascades to lower
this afternoon and evening, for continued n-nw onshore winds this
afternoon and evening. ~tj
the remainder of the discussion is from the previous issuance sent at
318 am... Not a lot of change Saturday. A weak short wave still
lingers near the coast, and we should see some night and morning low
clouds again along the coast, and a little bit inland especially
north. Again, anything that forms should not last long with plenty of
sunshine, especially inland. Temps inland on Saturday should reach
the mid to upper 80s.

Sunday starts to see the upper high in the southwest u.S. Expand
northwestward into the pacific northwest. After some local morning
low clouds, 500 mb heights approach 590 dm. Temps inland should reach
85 to around 90 based on 850 mb temperature considerations. Tolleson

Long term No changes. Previous discussion follows... Sunday night
through Thursday... The upper level ridge that strengthens on Sunday
continues through much of the coming week. 500 mb heights approach
the lower 590s. Despite the southwest flow aloft, we should see less
low clouds even at the coast as the marine layer will be shallow. 850
mb temps are indicating temps inland will be in the 90s, perhaps the
upper 90s or even close to 100 during the mid week period. We might
start to see temps ease a little late next week but still remain
above normal. Tolleson

Aviation MVFR stratus has filled in much of SW washington to
the cascade foothills, the north oregon coast and inland valleys
and up the columbia river to near kpdx. Inland areas becomeVFR
by 17z or so. Coastal areas hold on to ifr MVFR through 19z, but
improvement toVFR may not occur along the S washington coast
until early afternoon. Ifr to low-end MVFR returns to the
coastline after 03z Sat and moves up the columbia, reaching kkls
10z to 12z.

Kpdx and approaches... MVFR CIGS reached the terminal around 1530z
and will persist through 17-18z.VFR clear thereafter, but there
is the potential for ifr to low-end MVFR stratus to return around
sunrise sat. Weishaar

Marine Rather persistent pattern over the waters for the next
several days. High pres to dominate the waters in conjunction
with a surface thermal trough over the N california and S oregon
waters. This thermal trough will vary in strength over the next
few days. Latest model runs suggest possible 25 kt wind gusts
over the the far south end of zones 255 and 275 during the
afternoon and evenings over the weekend. The best chance for
small craft advisory wind issues look to be Sun and mon
afternoons and evenings.

Seas will be 5-6 ft or less for the next several days. Expect
choppy conditions due to relatively short periods. Weishaar

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.
