Synopsis High pressure over the region will maintain dry
conditions, with mostly clear skies. Will see warming temperatures,
with afternoon highs quite a bit above normal for Mon through thu.

Cooler air with return of shower threat by end of the week through
next weekend.

Short term Tonight through Wednesday... Expect dry conditons
through midweek as an upper level ridge slowly moves across the
region. Low level flow will turn offshore tonight as a thermal
induced trough builds north just off the coast. Models tend to show
the trough shifting onto the coast during the afternoon mon, and a
little inland during the late day Tue and wed. Temps inland will
warm into the 70s Mon as 850 mb temps warm to around 8 to 12c, then
are likely to top 80 at many interior locations Tue and Wed as 850
mb temps warm to 14c Tue and 16c wed. At the coast, the offshore
breezes early in the day should allow for a quick warm up each day,
but as winds turn back onshore sometime in the afternoon, expect to
see the diurnal temps rise cut off. Of course timing for this is
critical to hitting the high temp forecasts, and right now it
appears in general the southern parts of the coast are likely to see
the temps cut off earlier, likely limiting highs there to the 60s,
with 70s more likely along the north part of the coast.

Long term Wednesday night through Sunday... The general idea of
the cutoff low off the north ca coast slowly approaching the coast
late in the week suggests some moisture spreading north in the
southerly flow aloft for increasing chances of showers beginning
late Thu or Thu night. The pattern with a SE flow aloft can also
suggest the possibility for thunderstoms, particularly over the
cascades, but for now will leave out the mention as GFS soundings
not indicating sufficuent instability. Temps will be cooling back
down closer to normal as onshore flow resumes. While models begin to
show more significant differences by the weekend, the net result is
still plnety of clouds, chances for showers, and seasonable temps.

Aviation Vfr conditions to dominate for the next 24 hours.

Winds gusting around 20-30 kt at the coast and around 20 kt
inland, for late this afternoon.

Kpdx and approaches...VFR conditions continue to dominate. Will
maintainVFR for the next 24 hours. Northwest to north wind gusts
approaching 20 kt for a few hours centered around 22 00z. Mh

Marine Thermal low pressure over northern california will
continue along the oregon coast through Monday. This will be a
typical summertime northerly wind pattern that will bring gusty
winds across the waters. Small craft advisory level wind gusts
of 25 kt will continue across the central oregon waters. These
winds will likely push further north into the northern waters,
mainly south of CAPE meares, but could reach as far north as the
columbia river mouth late this afternoon and evening. The
persistent northerly winds will generate choppy seas, therefore a
small craft advisory hazardous seas is in effect through this
evening for the central coast zones.

Winds look to turn offshore on Monday and Tuesday, with wind
gusts of 20 to 25 kt possible near the coastal gaps such as the
mouth of the columbia river. A southerly wind reversal may
develop towards the middle to latter half of this week with seas
likely remaining under 10 ft.

Small craft advisory level winds, could return towards the
weekend, as a front moves into the north oregon and south
washington waters. Mh 42

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.
