SHORT TERM. Today through Sunday night. Upper ridge building into the region today with a dry northwest flow aloft. Satellite showing clear skies early this morning. Expect sunny and warmer today with highs in the 80s. Ridge continues to build in Saturday with a low off the California coast. This turns the flow more southerly and starts to increase the instability late in the day over central Oregon. Temperatures will rise another 5-10 degrees with highs in the 90s. Mid level moisture and instability increase Sunday and we will have a chance of thunderstorms in the afternoon and evening. Temperatures Sunday will depend on cloud cover however 850mb temps support 100-105 for the Columbia basin and valleys. Any lingering smoke and haze in the gorge and Columbia basin today should get pushed out tonight and Saturday as the low level flow turns easterly.
LONG TERM. Monday through Friday . Long term period will continue to be dominated by strong high pressure over the southwest US with ridging extending up into SW Canada. In addition, persistent upper level trough remains off the west coast. Monday into Tuesday will still be hot but a touch cooler than Sunday as the ridge axis is expected to be just east of the CWA. Highs will be mid 90s to lower 100s. Our area will be under south to southwest flow aloft. This will allow for some mid-level moisture to work north around the western periphery of the ridge through CA/NV and into eastern OR/WA. Expect possible showers/storms, mainly over the higher terrain of eastern OR/WA. Lingering convective debris in the daytime could also help to keeps temps a couple degrees cooler Mon/Tue. The ridge is expected to flatten a bit for Wednesday as trough/front tries to traverse the PacNW. This could help kick off a few showers/storms, mainly across the eastern mountains. Temps will be cooler as well, with highs in the mid 80s to mid 90s. Models differ a bit as we head towards Thu/Fri with amplitude of the ridge and location of ridge axis. General trend is for ridge axis to strengthen and settle somewhere over eastern OR/WA and ID. This will likely result in south to southwest flow aloft. Highs Thursday should be similar to Wednesday(mid 80s to mid 90s), but climbing a couple of degrees Friday.
AVIATION. 12Z TAFs . VFR conditions expected with just a few high passing cirrus. Winds should generally be less than 10kts and diurnally terrain driven. A fire southwest of DLS could bring reduced vis due to smoke, esp in the early morning when the inversion is the strongest, but confidence is not high enough to include in the taf.

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.
