Area Forecast Discussion National Weather Service Pendleton OR 408 AM PDT Fri Jul 3 2020

. UPDATED AVIATION DISCUSSION .

SHORT TERM. Today through Sunday night . No major weather concerns are anticipated this holiday weekend, but early July typically brings concerns for wildfires and this weekend is no exception. Temperatures will be near seasonable, afternoon RHs will be in the teens and 20s for many areas, winds will be locally breezy, and there will be cumulus buildups with isolated showers and thunderstorms.

The forecast area will be under a positive tilt trough and southwest flow aloft today and tonight. Mid level moisture is limited but there will likely be cumulus buildups this afternoon and evening over central and northeast Oregon. Isolated showers and thunderstorms are possible along the Wallowa Mountains and Elkhorns, but there is no apparent disturbance to trigger anything more than isolated thunderstorms. Breezy winds will once again develop in the eastern Columbia River Gorge, north central Oregon, and the Kittitas Valley but the wind/RH threat for red flag is not expected. Today's temperatures will be several degrees warmer than yesterday with highs mainly in the mid-70s to mid-80s.

The trough will nudge eastward and will be located over WA/OR tomorrow. Despite its position over the region, it's hard to get excited about showers and thunderstorms except over Wallowa and southern Union Counties. It will be mostly a dry southwest flow aloft and most of the mid level moisture will be over southeast Oregon with Baker County having the best potential for showers and thunderstorms. Saturday will be a tad cooler than today, and winds will generally be west-northwest 10-20 mph with higher gusts in the eastern Columbia River Gorge and Kittitas Valley.

A dry westerly flow will follow Sunday and Sunday night. Little change in temperatures, humidity, and winds can be expected. Once again, the holiday weekend is looking relatively benign weatherwise. Wister

LONG TERM. Monday into next weekend . Troughing will persist into next week with shortwave troughs rounding the broad pattern periodically pulling upper level flow more southerly. These shortwaves may provide enough lift for an isolated storm in Wallowa County each afternoon but moisture and instability will make anything beyond a shower/storm over the Eagle Caps tough to come by. The 'shortwave of the day' meaning the current shortwave models advertise as being potent enough to aid in surface instability and moisture issues is poised for Thursday afternoon where more than an errant storm on the Eagle Caps may be possible. These shortwaves of the day have been shifting to and from different days though and would stress storm chances appear quite low region-wide overall, even in Wallowa. RHs will be low, but not critical, in this period with breezy but not windy conditions each afternoon. Overnight RHs still expected to rebound well. The longer term, toward next weekend, shows cracks in the current trough pattern: GFS solutions over past day or two continue to insist on trough axis right near Cascades keeping a cooler flow over the region but non-GFS consensus currently advertises seasonal strengthening of high pressure in the southwest bringing the ridge axis further west, along the Rocky Crest, and displacing the trough toward the US west coastline. Should this displacement of our pattern westward occur, would expect temperatures to actually be seasonably hot for next weekend with possible increases in storm chances along a line from central OR to Wallowa. Clark/76

AVIATION. 12Z TAFS . VFR conditions expected throughout the period. Upper low near Vancouver Island may promote few high clouds. Otherwise, only few Cu expected through afternoon period. Winds lighter than previous days but still may be breezy, 15-20kts, this afternoon particularly at KDLS. Clark/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.
