NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Portland or 
819 PM PDT Friday Aug 1 2014 


Synopsis...little change in the overall pattern. High pressure 
remains intact over the NE Pacific...with mild SW flow aloft over the 
region. Weak disturbances in the flow will trigger afternoon/evening 
thunderstorms...mainly over the Cascade crest and points eastward. 
&& 


Short term...another active evening over the Cascades...but not 
showers and thunderstorms were not as extensive as this time Thursday 
evening. Still have few storms around Montana Hood...but otherwise 
activity significantly quieter. Instability much less this 
evening...so have removed all threat of showers/thunderstorms for 
most of the region tonight. This will keep nearly all areas dry 
tonight...but will keep minor threat on the Cascades crest. 


With high pressure remaining intact over the NE Pacific...so will the mild SW 
flow aloft. This will maintain status quo on temperatures over the 
next several days across the region. 


The marine layer will increase along the coast tonight with some low 
clouds moving inland along the Columbia River to about the Portland 
area by Saturday morning. Likely see areas of low clouds in the 
south and possibly central Willamette Valley due to onshore flow 
through the Siuslaw and Philomath gaps. 


Overall...little change for pattern for Sat night and Sunday...as 
Sunday likely to be a Carbon copy of Sat. Only difference is that 
will be a few degree cooler for most areas.Rockey. 


Long term...models remain in pretty good agreement showing the 
region under a weak 500 mb flow through most of next week. There will 
also be some low level onshore flow as a result of the high pressure 
over the NE Pacific. Overall...expect a dry pattern with the flow 
aloft favoring a light westerly wind...and temperatures remaining a bit 
above normal. 
&& 


Aviation...widespread VFR conditions prevail...except for 
increasing IFR conditions along the central coast as marine 
stratus begins to penetrate nearby coastal gaps. MVFR/IFR marine 
stratus will attempt to push up the Columbia River after 12z 
Sat...but shallow nature of moisture may limit the upriver drift. 
Smoke from wildfires across southwest Oregon will continue to 
impact the southern and eastern portions of the forecast 
area...but with no significant reductions to visible. Thunderstorms 
will primarily stay over the Cascades overnight...possibly impact 
northeastern taf sites. 


Kpdx and approaches...VFR conditions through 18z Saturday. 
High end IFR/low end MVFR conditions may spread up the Columbia 
River and impact the terminal primarily between 13z and 18z 
Sat. /Neuman/27 
&& 




Pqr watches/warnings/advisories... 
or...WA...pz...none.
