Area forecast discussion 
National Weather Service Pendleton or 
810 am PDT Friday Oct 31 2014 


Update...the latest radar was showing a large area of rain along 
the Washington/or Cascades in association with a cold front that is forecast 
to move across the region today. Showers were developing ahead of 
the front over the Columbia Basin and this should expand in coverage 
throughout the day. The front will work its way east and position 
itself along the Washington/or foothills and Blue Mountains later this 
afternoon. The showers should decrease over the ykm/eln valleys and 
over and near the central Oregon this evening as drier air works its 
way into the region. Otherwise afternoon temperatures will be cooler 
than yesterday.

Previous disc... /issued 434 am PDT Friday Oct 31 2014/ 


Short term...today through Sunday...an upper trough is digging off 
the coast causing a south to southwest flow aloft over the forecast 
area. A cold front associated with the upper trough is moving very 
slowly into the Cascades at this time. Rain has been falling over 
the east slopes and into the western Yakima and Kittitas valleys. 
Elsewhere there are a few showers but it is dry for the most part. 
An upper level jet is parallel to the cold front which is why it is 
moving so slowly. It is expected to move east to the Blue Mountains 
by 00z this afternoon and then it will get hung up over The Blues as 
a surface low deepens over Idaho and southwest Montana. This will 
result in a prolonged period of rain and higher mountain snow in The 
Blues...Wallowa and Elkhorn Mountains through Saturday evening. 
Colder air moving in behind the cold front will cause snow levels to 
drop to around 4500 feet by 00z Sunday and then they will be nearly 
steady after that. There could be some snow accumulations in the 
Blue Mountains above 4500 feet from Saturday afternoon through 
Sunday morning...but any snow accumulation is expected to be light 
with perhaps a few inches. The cold front will move out of the area 
by Sunday afternoon with drying taking place from west to east. 
Temperatures will begin near normal today and then will cool to 
about 3 to 5 degrees below normal on Saturday and Sunday. Winds will 
be locally breezy at times Saturday afternoon and night over north 
central Oregon...otherwise expect mostly light winds. 88 


Long term...Sunday night through Thursday night...a low pressure 
system from the Gulf of Alaska will transport moisture across the 
interior Pacific northwest for much of the extended. The 
aforementioned low will then deepen off the or/Washington coast and provide 
a more warm southerly flow to the area by midweek. The best break 
in precipitation looks to be Thursday. Middle and high level clouds 
are expected to remain with this southerly flow...but the east 
slopes of the Cascades will still hold onto a chance to likely 
showers along the crest. Expect the chance for precipitation to 
spread across the forecast area Thursday night as the cold front 
passes. While temperatures will be noticeably cooler after the 
frontal passage...models do not anticipate snow levels to fall below 
6000 feet. Weber 


Aviation...12z tafs. Frontal boundary with steady rain over central 
Oregon/Washington continues to move slowly east. Low ceilings and 
fog will create MVFR/IFR conditions at most taf sites through middle 
morning. Expect mostly MVFR to marginal VFR conditions from 15z 
Onward. Ceilings are expected to change from scattered-broken changing categories 
frequently over short periods of time...especially when 
precipitation is nearby. Winds mainly 5-15kt. Weber
