Updated Aviation Discussion
UPDATE. Satellite showing clear skies on the eastern side of the Cascades this morning, with a pretty decent marine layer west of the WA Cascades. Today, region will be under a weakening dry westerly flow aloft, with clear skies expected to continue through tomorrow. Breezy conditions will develop through the Cascade gaps this afternoon. With coastal soundings showing a decently deep moisture profile, have decided to bump up winds in the Kittitas valley and Columbia Gorge for this afternoon. Otherwise, forecast is on track. Lawhorn/82
AVIATION. 18Z TAFs . CLR skies and winds less than 15 kts are expected. There will be gusts around 20-25 kts this afternoon and evening at DLS, RDM, and PDT. Wister
PREV DISCUSSION. /issued 457 AM PDT Mon Aug 3 2020/
SYNOPSIS . Quiet and seasonably warm start to week gives way to storm chances in Oregon Wed afternoon and windy conditions Thu before a late week cool off.
SHORT TERM . Today through Thursday morning . Today to be near seasonable August day with highs in the low 90s in the Basin, upper 70s mountains. RHs to be dry in lower elevations, but not quite critical. Winds to be light with usual afternoon breeziness in Columbia Gorge and Kittitas Valley. Tuesday to be much of a copycat of Monday with slightly more warmth and less RH as quick ridging tries to build behind our exiting trough. Wednesdays weather to focus on cutoff low ejecting out of NE California toward central Idaho. Though this is a rather benign feature, conditional instability lent from summers heat combined with modest synoptic lift is likely to create isolated storms in the corridor of elevated terrain from central Oregon to Wallowa County. Still a little early for shorter range guidance but model guidance available suggests a few strong pulse storms initiating SW to NE along southeast CWA border. Lightning to ease early Thu morning but thinking advected moisture from previous storms and continued progress of shortwave trough overnight may promote shower activity and a few rumbles of thunder in the Blue Mtns and foothills, Wallowa County, and possibly as far north and west as Tri Cities. 76
LONG TERM . Thursday evening into next week . Aforementioned shortwave and associated cutoff low will be 'kicked' by much broader trough anchored near Vancouver Island on Thursday. RHs are likely to be moist for August, but gusty to downright windy conditions are indicated in model guidance for late Thursday. Will be monitoring these winds for wind or fire highlights if winds trend stronger for the former or RHs trend quite a bit drier for the latter. This active trough pattern gives way to pleasant weak westerly flow Friday with cooler temps. Cutoff low in CA and approaching British Columbia kicker trough pattern almost repeats itself late Friday through Saturday but cutoff low feature will be much more removed to our SE and doesn't appear to be a major factor in our late week weather. Trough will drag another burst of winds across the area, likely Saturday night, before next week starts with another day or so of depressed temperatures. 76

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.
