Forecast Discussion

Synopsis...An upper level ridge will remain over the northwest u.s. For several more days for dry weather. Surface high pressure will remain entrenched east of the Cascades and will maintain the offshore wind flow...though not quite as strong today and Sunday as it was on Friday. A system out near 140w early this morning will lift north off the coast today. Offshore gradients will increase again later Sunday through Monday for more dry weather. A splitting system May bring a small threat of precipitation to our forecast area Tuesday.

Short term...The upper level ridge that has been over the area the last couple of days will remain in place into next week. Pressure gradients that peaked at near 10 mb offshore from kttd to kdls Friday are now near 7 mb and are expected to remain in that range today and Sunday. Thus look for peak winds in the western end of the gorge closer to 50 mph versus the over 70 mph that occurred at crown point Friday. We might start to see a little fog form the next couple of mornings mainly in the South Willamette Valley and possibly north of kelso. Otherwise look for rather cold mornings in wind sheltered areas and a bit above average temperatures in the afternoons. There is a decent looking system out near 140w early this morning... But the models all say it will lift north but remain off the coast tonight and early Sunday. We May see some higher clouds from it inland. The far outer coastal waters might get brushed with a few sprinkles...with some lower clouds moving into the coastal waters as winds turn a bit southerly again...but it is not clear whether any of these lower clouds will reach the coast. The winds turn more offshore again Sunday afternoon push any low clouds away. The next upstream system approaches Sunday night and Monday but will remain offshore through this period. Main effect is an increase in the offshore wind flow...so look for more easterly breezes and a minimum of fog. This system will likely be splitting as it reaches our area Tuesday so we will see if we get much if any precipitation from it. Decided to cancel the air stagnation advisory for all of our area. High temperatures in the valley were near 60 yesterday with plenty of wind. Conditions look similar today and Sunday. Air quality is currently pretty good for most areas and do not expect this to change.

Long term...No changes. Previous discussion follows. Dry pattern holds through a much deeper low in the ern Pacific approaches the coast late Monday into Tuesday. This coupled with a colder air mass dropping south out of canada into the northern rockies will allow the offshore gradient to become even stronger. Models continue to advertise a weak system pushing through the ridge on Tue. However...it looks like a lot of the upper level energy will dive south into California...limiting the impacts for the forecast area. It appears the coast and southern inland areas stand the best chance to get some light precip Tue. After this system...the ridge will rebuild again...keeping the weather quiet for another couple of days. Weishaar/brown

Aviation...Vfr conditions will prevail throughout the district through this evening. Some areas of mvfr stratus will linger hood river eastward. Gusty east winds will continue today...mainly along the coast and near the gorge. Kpdx and approaches...vfr conditions through this evening with dry light to moderate east winds.

Marine...East winds are locally gusting to 25 kt below coastal canyons today...otherwise expect light to moderate offshore flow to continue through Sunday. Storm activity well offshore continues to generate west swell 11 to 13 ft today...this will continue through Sunday night. The next chance of small craft advisory winds looks to be Mon and Tue...with e-se winds increasing ahead of the next front. Another batch of swell arrives Tue bringing seas to around 12 ft. Weagle

Pqr watches/warnings/advisories... Or...none. WA...none. Pz...small craft advisory for hazardous seas until 6 AM PST Sunday for coastal waters from cape shoalwater to florence out 60 nm. Small craft advisory for rough Columbia river bar until 4 AM PST Sunday.
