Area forecast discussion...updated 
National Weather Service Pendleton or 
930 am PST Monday Nov 23 2009 


Updated aviation discussion 


Short term...high pressure that is providing a mostly sunny 
beginning will give way to a disturbance moving into the pacnw this 
afternoon. This should spread clouds into portions of the area 
especially over the Washington Cascades where a few showers may develop late 
this afternoon and then spread east later on. Otherwise high temperatures 
seem to be in the ballpark and the short term forecast appears on 
track for now.

Aviation discussion...18z tafs...VFR conditions will prevail 
through the day today with increasing middle and high clouds this 
afternoon. Another weather disturbance will move into the area 
overnight tonight with another chance of rain and mountain snow. 
Krdm in central Oregon will likely not see any precipitation from 
this system. There may be brief periods of MVFR tonight in rain/snow 
showers...especially at kdls...kykm and kpsc...and to a lesser 
degree at kpdt and kalw. Winds mainly less than 15 kts...but perhaps 
15 to 20 kts at times near showers. 76
