Area Forecast Discussion National Weather Service Portland OR 245 AM PDT Fri Aug 7 2020

SYNOPSIS. Weather more representative of September for next day or two, with mild temperatures. Another weak front will push into western Washington early Saturday. But, rain stays well north of our area. Then, high pressure will build, with another warming trend for Sunday into early next week. Temperatures cool a bit again for rest of next week, with mostly dry conditions.

SHORT TERM. Today through Sunday . Onshore flow across the region continues today. Starting out with areas of clouds jammed against the Cascades, as well as the west side of the Coast Range and Willapa Hills. Overall, not a lot of change, as will see these clouds gradually break up this morning. Will see clouds across the interior lowlands, mainly north of Salem this am. Overall, rather pleasant day, with partly to mostly sunny skies, and temperatures only in the 70s for the interior, and 60s on the coast.

Next system will be approaching the Pac NW later tonight, with increasing clouds. Models have been suggesting that most of the precipitation with this system will be north of our area, primarily across northwest Washington and northward. Will trend towards that blend, but will keep a minor chance (20 pct) of showers for the coastal areas and coast mtns north of Tillamook for late tonight into Sat am. Even so, will see clouds farther inland, mainly north.

Skies again will gradually clear Sat afternoon, as lower to mid-level flow turns more northerly. Temperatures only a few deg warmer inland, with highs closer to 80 in the afternoon.

High pressure over the region builds through Sunday, with much warmer conditions for Sunday with mostly clear skies. Interestingly, the northerly pressure gradient will strengthen, thank to the building thermal low pressure over southwest Oregon. This will promote locally breezy conditions in the afternoon, with north winds 10 to 15 mph for many spots. This dry flow, combined with little if any residual marine layer and 500 mb heights pushing 590 dam, would expect high temps close to 90 deg for interior lowlands. /Rockey

LONG TERM. Monday through Thursday . As mentioned above, low amplitude upper ridging appears likely to build over Oregon and possibly Washington by Monday, leading to above normal temperatures inland. After Monday longer range models' solutions begin to differ, but the majority solution appears to favor some sort of upper trough development over the Pac NW by midweek. Again, models vary considerably on the strength of this upper trough and whether or not it will be strong enough to bring us rain, so we held close to the NBM solution which generally keeps our CWA dry. After a warm day Monday, temperatures should cool back closer to seasonal norms or perhaps slightly below that by midweek. /Weagle

AVIATION. Conditions remain VFR as of 08Z under mostly clear skies. With a stabilizing air mass, residual surface moisture, and calm winds expect patchy fog/low stratus to develop across the region over the next several hours with localized MVFR or lower conditions possible between 10-18Z along the coast and in portions of the northern interior. Otherwise, conditions remain mainly VFR with mostly clear skies through this evening.

KPDX and APPROACHES . Aside from a few hours of MVFR stratus in the vicinity between 10-17Z expect conditions to remain mainly VFR with mostly clear skies. /64

MARINE. A weak front will brush by the northern waters today. Otherwise, high pressure will build across the waters through early next week with thermal low pressure over the far south Oregon coast. This will result in periods of gusty northerly winds over the weekend with gusts to 30 kt possible south of Cascade Head and steep seas around 7-9 ft. Northerly winds continue through much of the upcoming week with occasional advisory gusts to 25 kt and seas around 5-7 ft. /64

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.
