Short term Today and tonight... One more day under a ridge of high
pressure which will provide warmer then normal temperatures and
mostly clear skies today. Will start to see some increasing clouds
overnight from an approaching upper level trough that will push a
cold front through the forecast area on Wednesday. This cloud cover
will help provide warmer than normal temperatures for overnight too.

Overall winds will be light with just some usual breezy conditions
through the columbia river gorge this afternoon.

Prev discussion issued 310 am pdt Tue aug 20 2019
short term... Today through Thursday night... Sw flow aloft will be
over the area for one more day resulting in hot afternoon
temperatures under mostly clear skies. High temperatures will be in
the 90s with 80s in the mountains. An upper level trough will
approach the area Wednesday and swing across the region Wednesday
night. This will move a strong cold front across the forecast area
late in the day into the evening. Main impacts from this front will
be a burst of gusty winds and a few rain showers. Winds could gust
in excess of 30 mph with the front and perhaps a bit stronger in a
few locations. However do not think there will be a prolonged wind
advisory event. Models are trending a little wetter with the front
and have at least some chance of showers over the entire forecast
area. QPF amounts look light. Airmass does not appear to be
supportive of thunderstorms so have left mention of thunder out of
the forecast. By Thursday the upper trough is east of the area and a
cool northwest flow aloft takes over. Highs on Thursday will be in
the upper 70s to mid 80s in the lower elevations with upper 60s to
mid 70s in the mountains. It will be cool Thursday night with lows
50-55 in the lower elevations and upper 30s to mid 40s mountains and
high plateaus. 78
long term... Friday through Tuesday... Models in good agreement
through Sunday, but begin to diverge thereafter. Dry northwest flow
aloft will continue at least into Sunday. Some weak embedded
shortwaves in the northwest flow will produce a short-lived increase
in cloud cover. Otherwise, the tranquil weather will continue. By
Sunday night, the new run of the ECMWF shows an upper level low
diving out of bc and clipping our northeast CWA by Tuesday.

Meanwhile, the GFS continues the dry, west to northwest flow aloft.

At this time, will lean towards the more persistent GFS solution and
keep the weather dry. Daytime temperatures will remain near to
slightly above normal through the period. Earle
aviation... 12z tafs... .Vfr conditions are expected through the
period with only thin cirrus moving through the area. Winds
will generally be 10 kts or less with higher gusts possible during
the afternoon, except kdls will increase to 12-16 kts by afternoon
with higher gusts. Winds will decrease overnight to less
than 8 kts. Earle

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.
