Short term Short wave that moved across the region last night
is exiting the forecast area this morning into central washington.

Satellite shows clear skies behind this wave and expect sunshine
through the morning into early afternoon. Upper low is moving
into northern california and will continue to move northeast
across the region later this afternoon and evening. There is
plenty of instability aloft and surface temperatures will quickly
rise into the 80s and 90s with dewpoints in the 50s. Expect
showers and thunderstorms to develop this afternoon and continue
through the evening as the low moves through. Increasing surface
gradients with a marine push today into tonight will result in
breezy west winds. 94

short term... Today through Wednesday... A weakening upper low is
roughly near 40n 128w early this morning. This low will be kicked
through the pacific northwest during the next 24 hours by a larger
low moving into western canada. Moisture has been flowing into the
region from california since Sunday. A fair amount of mid and high
level cloud cover will continue to drift across the region this
morning. A few very light showers will accompany this cloud cover.

As the upper low approaches the region this afternoon it will cause
a marine push cool front to move east of the cascades. Thus the
combination of this boundary, increasing moisture and energy from
the system will cause isolated to scattered thunderstorms this
afternoon and the evening. The best coverages of storms will extend
from deschutes county east to grant county, and northeast to the
blue mountains, grande ronde valley and wallowa county. Spc
continues to indicate a marginal risk of severe thunderstorms for
portions of our area. Shear looks to be strong enough to produce
strong gusty winds and some hail from grant county northward and
northeastward late this afternoon and this evening. West of this
area, shear looks to be generally less than 30 kts with only general
thunderstorms expected. Breezy winds in the columbia river gorge
will gradually spread eastward today, especially in the afternoon
with the marine push cool front. Cooler and fair conditions are
expected Tuesday and Wednesday due to the return of a dry west to
northwest flow pattern. 90
long term... Wednesday night through Monday... An upper trough will
departing the region Wednesday night and it will be replaced by
building high pressure aloft again by Thursday night into Friday. At
first the flow will be from the northwest ahead of this upper ridge
which will first build off the coast before it moves eastward into
the region. This will keep temperatures from getting too warm.

However with building heights and 850 mb temperatures can still
expect warm conditions over the CWA on Thursday with a warming
trend. There may be locally breezy winds Wednesday evening but the
winds will become light overnight into Thursday. The warming trend
will continue through Friday and then temperatures after that will
be nearly steady with highs in the mid 80s to lower 90s in the lower
elevations and mostly 70s to lower 80s mountains. Precipitation is
not expected in the extended range forecast and winds will be light
throughout. 88
aviation... 12z tafs... A weather system and cold front will move
into the region today bringing scattered showers and isolated
thunderstorms. This may cause brief MVFR conditions near and under
thunderstorms due to lower CIGS and visibility. OtherwiseVFR
conditions will prevail during the next 24 hours. Winds will be
light at all TAF sites until 18z today and then they will
increase... Especially at kdls first and then spreading eastward to
include TAF kpdt... Kalw... Kpsc and kykm. Winds at krdm and kbdn will
remain light and under 15 kts. 88

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.
