Update Minor updates to the grids this morning. Upper-level low
over the desert southwest will slowly meander north and east
through tomorrow. Ridging is trying to build over the low and
work into our region. Expect drying and warming conditions today
through tomorrow. Still expect a chance of showers and isolated
thunderstorms this afternoon evening over the
cascades blues wallowas into central or as mid-level moisture
continues to wrap around the northern periphery of the low. Expect
highs in the mid 50s to mid 60s mountains and upper 60s to mid
70s in the valleys and basins. Tomorrow looks to be drier and
warmer as the low works away from the region. Could still see an
outside shot for a few showers storms over the mountains. Highs in
the upper 50s to 60s mountains and 70s to low 80s in the valleys
and basins. With low off to the south, north to northeast winds
will pick up this afternoon and again 10-20 mph with some higher
gusts in central or. Friday into the weekend, another upper-level
low is expected to drop south out bc, over the pacnw and settle
over the desert southwest. This will bring a good chance for
showers and thunderstorms, mainly over the mountains, along with
cooler temps.

Aviation 18z tafs...VFR conditions will prevail through the
period. Mostly mid and high clouds are expected with a tendency for
clouds to thin out a bit tonight. Some stratocumulus will persist
into the evening at kbdn and krdm with the potential for vcsh this
afternoon. Winds will be the primary concern with north winds at 15
to 25 kt and some higher gusts diminishing after sunset... Becoming
mostly light over night. 78

short term... Today through Friday... There is an area of showers
moving across north central and northeast oregon this morning in a
wrap around flow around an upper low pressure system over the desert
southwest. Expect this pattern to persist through tonight. There
will be some instability this afternoon mainly along the cascade
east slopes where there could be a thunderstorm or two this
afternoon and evening. Elsewhere expect isolated to scattered
showers today over the eastern and northeast mountains. The showers
will decrease and end by late tonight due to the loss of surface
heating. The lower columbia basin and adjacent lower elevations
should remain dry today. Thursday will be similar to today. The
upper low over the southwest will begin to lift to the northeast.

There will again be enough moisture and instability again in the
afternoon for possible thunderstorms along the cascade east slopes.

With the upper low departing to the northeast the eastern areas of
the forecast area will be mostly dry and as a result did not include
showers on Thursday in the eastern areas of the cwa. Then on Friday
another upper low pressure system will drop southward from western
bc into the pacific northwest. This system will bring a better
chance of showers and especially afternoon thunderstorms over most
of the forecast area. There could be a couple to a few strong
thunderstorms on Friday, but most will not be strong. But the areal
coverage will be much greater than today or Thursday. Temperatures
will warm today to the upper 60s to mid 70s in the lower elevations,
then warming further to the mid 70s to lower 80s on Thursday, but
then cooling back down to the upper 60s to mid 70s on Friday. These
temperature forecasts will be the result of more clouds today and
Friday, but less on Thursday. It will be locally breezy through the
period, mainly in the afternoons and evenings, and especially near
any showers or thunderstorms. Winds will be mostly light by the late
night hours each night. 88
long term... Friday night through Tuesday... At the beginning of the
extended period, a potent shortwave will be dropping into the
pacific northwest and this will cause a strong deepening of the
longwave trough beginning Saturday and continuing into Sunday before
the trough begins to move eastward. The upper low will be over
washington and oregon on Saturday and will drop into california by
Sunday, and gradually push into the great basin by Monday. The
guidance has some short term ridging by Monday behind the trough
before another low may begin to drop down Tuesday or Wednesday.

Guidance begins to diverge after Tuesday. With a large upper trough
in place, expect unsettled conditions over the weekend, though it
will not be rainy the whole time. With the proximity of the upper
low, there is a chance of thunder especially Saturday and into
Sunday. Best on the latest guidance, less confident into Tuesday.

If guidance trends continue will likely remove thunder chances for
Tuesday and possibly Monday in later forecasts. Temperatures should
begin a slow warming trend after Saturday.

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.
