Synopsis High pressure builds aloft today and a thermally induced
trough sets up across the willamette valley. This will result in
warmer temperatures today. The warming trend continues Monday as the
thermal trough intensifies. Inland afternoon temperatures will remain
in the low to mid 90s through the end of the week as the strong upper
ridge persists.

Update Updated sky cover and weather along the coast for
this morning due to observed fog and clouds. The clouds are shallow
and should clear quickly mid morning. ~tj
previous short term... Today through Wednesday. Marine clouds are
developing along the coast early this morning. These clouds are
shallow and sticking close to the coast line. Winds near 925mb (just
above the surface) are offshore and will increase this morning. This
will move the clouds along the coast offshore and minimize the
inland influence of the marine air today. The coastal 925mb winds
become north this afternoon except for north of pacific city, where
downsloping may result in warmer surface temperatures. Have
increased the afternoon temperatures for the SW washington coast
down to tillamook for this afternoon. Temperatures for these coastal
areas will peak in the mid 70s to low 80s with the warmer
temperatures expected 5miles or so from the beaches.

Inland temperatures will be warmer today too due to the lack of
marine influence, a warmer airmass from a building upper ridge, and a
thermal induced trough setting up just west of the cascades.

Temperatures in the interior valleys will peak in the low to mid 90s
this afternoon, which is 10 to 15 degrees warmer than what was
observed for yesterday. These hotter temperatures will result in
delayed cooling tonight with temperatures not cooling below 70
degrees until midnight or slightly after midnight. The temperatures
will lower down to the upper 50s to low 60s before sunrise for a
brief relief from the heat.

As the thermal trough intensifies this afternoon it shifts slightly
east towards the cascades and there will be a brief period of east
winds over the north oregon and washington cascades, and southeast
winds along the cascades of lane county and just south of the lane
county cascades. This may allow smoke from wildfires south of the
area to move over the cascades impacting lane county. This smoke is
not expected to be terribly think, but it will haze up the skies, and
possibly provide a smokey smell. Smoke from the wildfire near the
dalles is expected to be less intense today so do not think smoke
will move into the willamette valley or impact the northern cascades.

Temperatures heat up for Monday as the thermal trough widens and the
strong upper ridge holds. Light onshore flow for the coast should
prevent much heating for the coast, especially since the 925mb
coastal winds lose the east component. Interior temperatures though
will warm up into the upper 90s. Onshore winds increase in the
afternoon and reduce the likelihood that temperatures will warm into
the triple digits. Evening temps will be warm and possibly still in
the 80s around 10 pm. Models suggest that the thermal trough shifts
slightly east on Tuesday for slightly cooler, but still hot inland
temperatures Tuesday afternoon.

The thermal trough should be east of the cascades on Wednesday for
slight cooling west of the cascades. The models have cooled
temperatures a couple of degrees, but am not convinced that the
cooling will be noticeable, and am forecasting similar temperatures
for Wednesday as Tuesday, with better night time relief.

Have replaced the excessive heat watch for the interior valleys with
a heat advisory as there will be the potential for heat related
impacts. The advisory is currently from Monday afternoon through
Tuesday evening. Am less confident on the Wednesday temperature
forecast so did not include Wednesday in the advisory, although it
may be included with future updates. ~tj

Long term Wednesday night through Saturday... An upper level trough
will result in more of a marine influence Wednesday night and
slightly cooler temperatures Thursday and Friday. The inland
temperatures will still likely be in the 90s though continuing the
stretch of warm and dry weather. Models are forecasting the upper
ridge to amplify next weekend with inland temperatures returning to
the upper 90s. Tj

Aviation Northwesterly surface winds have allowed for some
shallow marine stratus to develop along the north oregon south
washington coast. As this will be fighting with increasing
offshore winds just above the surface, think that it may only
last a few more hours before it erodes back off the coast.

Besides that,VFR conditions for all our other terminals through
the next 24 hours. It should also be noted that smoke from
southwest oregon up around 10kft asl will begin to spread over
eastern lane and linn counties today.

Kpdx and approaches... A northwesterly low level flow pattern
under building high pressure aloft will lead to primarilyVFR
conditions through 12z Monday. -mccoy

Marine High pressure over the northeast pacific and thermal low
pressure over southwestern oregon will result in a fairly typical
summer-time northerly wind pattern for much of the next week. Expect
wind gusts of 25 kt across the central oregon waters through tonight
across the inner waters and into the first half of Sunday across the
outer waters. Do not think steep and hazardous seas criteria will
be met, but it's not impossible either. Otherwise, winds and seas
look to remain mostly below advisory thresholds during the upcoming
week across our waters except across the central oregon waters from
time to time when northerly winds may temporarily spike up to 25 kt
during the afternoon and evening hours. Mccoy neuman

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
