Short term Tonight through Friday... Upper low over SW ore will
move sewd reaching SE ca before lifting newd across the rockies to
the northern plains by Friday. Another upper low will close off
across ore wa during the day on Friday. The band of rain over
northern ore and extreme SRN wa that has persisted for much of the
day is showing some signs of weakening. This is in line with the
latest hrrr. Aside from this expect scattered late afternoon and
evening showers especially mountains. Could be a few lightning
strikes in central oregon especially deschutes and crook counties
where some buildups are already evident on visible satellite
imagery. For Wednesday and Thursday expect widely scattered mainly
afternoon and evening showers mainly over the higher terrain and
especially near the cascade crest... Where an isolated thunderstorm
or two will be possible. It will be warmer with near seasonable
temperatures expected. Friday looks to be the most active day
especially in the afternoon if daytime heating can destabilize the
air mass. At least isolated thunderstorms will be possible in the
afternoon over the central and eastern mountains and across south
central wa. There will be some locally breezy winds the next few
days but at the present time it looks like winds will be below
advisory criteria. 78

Long term Friday night through Tuesday... Long term period will
continue to see the persistent pattern of long wave troughing over
the western us with ridging over the southeast. General model trend
shows upper-level low continuing to drop south out of bc across the
pacnw down towards the cali coast through Saturday. The low is then
expected to slowly waddle east across the southwest towards the
central us through Tuesday. A few waves are expected to pivot around
the main low into the pacnw. Expect the potential for showers each
day, especially over the mountains, with the best potential through
the weekend due to the likely proximity of the upper-level low to
the area. Enough instability will be in place for a few
thunderstorms as well through the weekend. Models diverge a bit past
the weekend, but may see some ridging trying to build in behind the
departing upper-level low that could bring warmer and drier weather.

Winds remain mostly light through the extended period, with some
increase with passing weather systems, but nothing significant.

Temperatures remain near to slightly below normal through Saturday
and then a warming trend takes place Sunday through Tuesday with
temperatures rising into the 80s in the lower elevations and 60s to
lower 70s mountains.

Aviation 00z tafs... An upper low over SW oregon continues to send
showers over the area this afternoon along with a few thunderstorms
over central oregon affecting kbdn and krdm. Showers will be heavier
to the south tonight and light to the north. Have kept kykm, kpsc
and kdls dry with vcsh at kalw and kpdt. Showers should linger
through 12z at krdm and kbdn. CIGS will generally beVFR but brief
MVFR CIGS will be possible with the heavier showers and
thunderstorms through 02z. Scattered showers will return tomorrow
afternoon to the mountains and central oregon and have vcsh for krdm
and kbdn after 20z. CIGS will continue to be broken to overcast
above 5000 feet agl. Winds tonight will generally remain below 12
kts aside from possible higher outflow winds from thunderstorms at
krdm and kbdn through 02z. Winds will begin increasing tomorrow
morning and will become northerly at 10 to 20 with gusts to 30 kts
in the afternoon. Perry

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com 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.
