Area forecast discussion 
National Weather Service Pendleton or 
357 am PDT sun Jul 6 2008 


Short term...today through Monday night...a weak weather 
disturbance is currently exiting the region. Middle to high level 
clouds are decreasing behind the system...with mostly clear skies 
expected over the entire region by this afternoon. A ridge of high 
pressure will begin to build today off the Pacific northwest coast. 
This will keep the area under a dry northwest flow through Monday 
night. Temperatures will be a few degrees warmer today than 
yesterday. Heights will rise as the ridge builds further on 
Monday...with high temperatures rising to around 90 degrees in the 
lower elevations and into the 80s in the mountains. Dmh 


Long term...Tuesday through Saturday...a flat upper level ridge of 
high pressure will persist from Tuesday through Wednesday night. 
Meanwhile...an upper level trough will enter British Columbia on 
Wednesday and sag southward Wednesday night with the trough invading 
the Pacific northwest on Thursday thus producing a marine push east 
of the Cascades that will increase surface pressure gradients 
resulting in breezy winds in the Kittitas Valley and the eastern 
Columbia River gorge. On Friday and Saturday daytime high 
temperatures will back off and be somewhat cooler thanks to a 
maritime airmass spilling east of the Cascades on Thursday. Polan
