Otherwise the dry conditions will continue and afternoon high
temps are forecast to climb into the 80s with 70s in the

Aviation 18z tafs...VFR conditions will prevail for the

southern wa northern or through this evening, otherwise mostly
clear skies can be expected. Winds will be lighter than yesterday,

Prev discussion issued 210 am pdt Sat aug 17 2019
short term... Today through Monday night... A northwest flow will
prevail over the region and the forecast area today and tonight with
an upper trough over the northern rockies and a high pressure system
over the pacific, about 950 miles off the oregon coast. This will
keep dry and stable conditions over the forecast area. Temperatures
today will be similar to Friday with maximum readings a little below
normal due to the cooler northwest flow. High temperatures today
will be in the mid to upper 80s in the lower elevations and mostly
70s in the mountains. These are just a couple degrees below normal.

The flow will then back and become more westerly and eventually
southwest by Sunday and Monday. Even though a southwest flow usually
means more instability and increasing moisture, there just is not
that much moisture to be pulled into the pacnw. As a result
conditions will remain dry. However, it will be a little warmer due
to the flow having a more southern origin. Temperatures will rise
back to become slightly above normal with MAX readings in the upper
80s to around 90 by Sunday and Monday in the lower elevations and in
the mid 70s to mid 80s mountains. Precipitation is not expected
anywhere in the forecast area through the entire short term forecast
period (through Monday night). It will become locally breezy in the
afternoons and evenings through the cascade gaps and the eastern
columbia river gorge. Elsewhere winds will be mostly diurnally
terrain driven. 88
long term... Tuesday through Friday... A southwesterly flow aloft
with dry weather and hot temps to start the long term, climbing into
the upper 80s to mid upper 90s for Tuesday and Wednesday. Models
begin to diverge a bit towards late week, but the overall general
trend is for an weakening upper-level trough to swing through the
pacnw Thursday, with the flow then turning more zonal to northwest
next weekend. Not overly deep moisture push with trough passage and
for now only looking for potential of a few mountain showers, mainly
over the wa cascades later Wednesday into Thursday, with dry
westerly flow out in the columbia basin. Another weak trough could
swing through over next weekend, with a few showers possible again
for the wa cascades. Cooler, more seasonable temps expected behind
the initial trough frontal passage with highs in upper 70s to around
90 on Thursday through Saturday. There will be occasional breezy
periods with marine pushes mainly Wednesday and Friday evening...

with the strongest wind in the kittitas valley and columbia gorge.

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.
