Synopsis Onshore flow will produce varying degrees of morning
clouds, afternoon sunshine, with inland temperatures in the 70s and
80s for much of the next week. Monday and Tuesday will likely be the
warmest days of the work week as a flat upper ridge moves through. A
weak system will bring significant cooling to the forecast area late
Wednesday and Thursday, as well as more clouds and a few light
showers to the forecast area Wednesday night and Thursday. Expect
drying as temperatures warm back to well above seasonal normals
levels next weekend.

Short term Today through Thursday... Fog channel and early visible
satellite imagery shows the fog and low clouds fairly solid along the
coast, with inland pushes to around kelso along the columbia river,
as well as into and through tillamook, siletz, and yaquina bays.

There are some thins spots near and north of manzanita, near road's
end, and near yachats. The clouds and fog along the coast may not
clear much until the end of the eclipse or early afternoon, but
probably not too far offshore in the afternoon. Inland south of
kelso is mostly clear, though some light east wind is starting to
cause smoke from the whitewater fire east of detroit and the fires
in eastern lane county to drift westward toward the valley. For the
most part, the eclipse will be easily visible inland except close to
the fires. The afternoon will be sunny inland except for some areas
smoke. A warming air mass from a building upper ridge will cause
temperatures to rise into the upper 80s to around 90 except mid 80s
near kelso.

The upper ridge shifts east a bit tonight and Tuesday with some
southwest flow aloft developing. This will cause the marine clouds
and fog to spread back onshore along the coast this evening and
tonight, but the inland penetration will be limited Tuesday morning.

The clouds will clear back to near the coastline Tuesday afternoon,
while inland areas will be mostly sunny Tuesday except for local
smoke around. The flow turns onshore inland Tuesday afternoon which
should help decrease the smoke after that. Inland temperatures will
again be very warm Tuesday, in the upper 80s to around 90.

Southwest flow increase Tuesday night and Wednesday as an offshore
system approaches. This will keep the marine layer solid along the
coast, but the models all say there should be a decent push of low
clouds inland Wednesday morning, especially along the columbia river
into the northern valley areas, and possibly in the southern coastal
gap areas into and around eugene. The inland clouds should burn off
in the afternoon, but expect the temperatures inland to cool off and
be closer to 80.

The system that approaches Wednesday moves through our forecast area
Wednesday night and Thursday for increasing clouds, cooler
temperatures, and a few showers. Temperatures will cool off to below
seasonal normals, with 70s common inland. Tolleson

Long term Thursday night through Monday... Shortwave ridging should
build over the pacific northwest and bring a return to more sunshine
and warming temperatures Friday and Saturday. In fact, some models
suggest another hot spell and dangerous fire weather conditions are
possible late in the weekend and or early next week, but still too
early to say much more than that at this point. Neuman

Aviation No changes... Stratus deck has filled in along the coast
now with ceilings between 200 and 400 feet. Kast has briefly broken
out of the stratus, but expect the stratus to return and remain
through the morning. The biggest question will be how quickly the
stratus clears. Given that 925 and 850 winds are slowly becoming more
ne between now and 18z, expect the stratus to clear quite
quickly... Possibly even in time for the eclipse. However, given the
slower daytime heating due to the eclipse, this may also limit mixing
and cause the stratus to linger longer than otherwise expected.

Kpdx and approaches...VFR conditions through the period. Still a
small possibility of a few scattered clouds this morning near the
terminal, but expect mostly clear skies. Bentley

Marine No changes... A persistent weather pattern will result in
little change in the marine weather the next several days. High
pressure will continue over the NE pacific with a thermal trough of
varying strength along the south oregon coast. This will lead to
small craft strength winds again today in central waters. Winds
should be below small craft strength through the remainder of the
week before northerlies strengthen again by the weekend as the
thermal trough strengthens again.

Seas will remain small but steep through the period. Dominant periods
will remain between 8 and 10 seconds. A rough bar is in effect for
the very strong ebb this morning. Otherwise, no sea driven headlines
should be needed this week. Bentley

Pqr watches warnings advisories
Or... None.

Wa... None.

Pz... Small craft advisory for winds until 11 pm pdt this evening for
coastal waters from cascade head or to florence or out 60
nm.

Small craft advisory for rough columbia river bar until 7 am
pdt this morning.
