NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Pendleton or 
224 PM PDT Friday Sep 19 2014 


Short term...tonight through Monday. High pressure will influence 
the region with dry conditions through the weekend with a warming 
trend expected into the beginning of next week. Afternoon high 
temperatures are expected to climb into the 80s across the basin. 
Meanwhile some moisture may work its way into the Washington/or Cascades 
Monday afternoon and a few showers are possible across this area. 
Otherwise dry conditions and above normal temperatures are expected 
for the next several days. 


Long term...Monday night through Friday...the long term period 
will be marked by a major pattern change around Wednesday as we 
transition from a ridge of high pressure to a trough of low 
pressure. The process will begin late Monday as a weak cold front 
attempts to pass over the ridge. Will see some increasing clouds and 
perhaps a few light showers mainly over the eastern mountains. The 
more significant event will occur as a second and stronger cold 
front is expected to arrive on Wednesday bringing a good chance of 
rain to the forecast area. The upper level trough will then settle 
over the area Thursday and Friday providing cooler and unsettled 
weather pattern. 


&& 


Aviation...00z tafs...VFR conditions are expected during the taf 
period with generally clear skies. Winds will be around 10 kts through 
the evening...exception being kdls where afternoon winds will be 
around 15 kts...then winds will become light overnight everywhere 
and less than 10 knots on Saturday.
