Short term Today through Wednesday... A large upper low
will continue to dominate our weather for the next few days.

Currently the low is centered over southern nevada and is sending
moisture into the area on an east to southeast flow. After a mostly
dry morning with just a few showers possible south of bend and in
the higher terrain of northeast oregon, am expecting another
afternoon of scattered showers and isolated thunderstorms over most
of the area. Convection will not be quite as active as yesterday as
the low is further away today. Have limited scattered thunderstorms
to the northern blues and wallowa county and have kept the columbia
basin dry. Thunderstorms will end rapidly with sundown and showers
will taper off as well, with a slight chance of showers overnight
limited to the oregon cascades and the eastern oregon mountains.

Under the heavier cells, a quarter inch of rain will be possible,
but most locations will just see a few hundredths of an inch. On
Tuesday the upper low will be moving through the rockies but there
will still be moisture circulating around the low into our area on a
northeast flow. The atmosphere will continue to be unstable and the
moisture will allow a chance of showers and a slight chance of
thunderstorms in the afternoon from central oregon through the
eastern oregon mountains and also in the washington cascades and
simcoe highlands with the rest of the area dry. Rain amounts will
just be a few hundredths of an inch. By Wednesday the upper low will
be weakening and located over kansas. It's circulation will cease to
affect us, but another weak low will form along the oregon coast.

This will lead to chance of showers and a slight chance of
thunderstorms once again in central oregon south of bend and in the
eastern oregon mountains while the rest of the area is dry. Rain
amounts in the higher mountains will be up to a tenth of an inch but
generally just a few hundredths of an inch. Temperatures today will
be 3 to 5 degrees higher than yesterday with highs in the mid 70s to
lower 80s and mainly in the 60s in the mountains. Tuesday and
Wednesday will be a few more degrees warmer with highs in the upper
70s to mid 80s in the lower elevations and in the mid 60s to mid 70s
in the mountains. Perry

Long term Wednesday night through Sunday... Another shortwave
will cause reamplification of the western trough starting Wednesday
night and continuing through Saturday, with some weak ridging
developing to the north by Saturday and another weak trough possible
by Sunday. With the flow becoming almost split with a more zonal
flow to the north over western canada and a more amplified pattern
to the south over southern california and the great basin around the
trough low, no major systems will be affecting our area. However,
there will be enough instability and moisture for afternoon showers
and thunderstorms basically each day, mainly over southern and
eastern areas through Friday. The large trough will begin to weaken
and fill by Saturday and some ridging will build to the north. There
are model disagreements what happen with the low after that, with
the GFS continue to weaken it while the ECMWF cuts the low off, but
both models bring a less amplified pattern over the north. However
the GFS wants to bring another weak wave into washington state and
the ECMWF is weaker with this system. Temperatures should see a
nice warm up through Saturday, well into the 80s... At the lower
elevations, before decreasing a bit on Sunday as the weak trough
bring cooler temps for Sunday.

Aviation 12z tafs...VFR conditions are expected at all TAF sites
today unless heavy shra or tsra are seen, in which case local MVFR
or even brief ifr are possible. Due to the nature of these shra and
tsra they are not being forecast at any individual sites, but would
not be expected until afternoon.

The only exceptions are rdm and bdn which have MVFR CIGS this
morning. They will return toVFR later this morning and remain
there unless they have showers or thunderstorms as well.

A northwest wind, which could gust as high as 20 to 25 kts is
expected during the afternoon at dls, pdt, bdn and rdm.

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.
