NATIONAL WEATHER SERVICE PENDLETON OR

DISCUSSION
 
A NORTHWEST FLOW THIS MORNING WILL BECOME WESTERLY  
BY NOON AND THEN SOUTHWEST BY LATE AFTERNOON. THIS CHANGE IN THE  
FLOW WILL ENABLE WARMER AIR TO BE PULLED INTO THE DISTRICT DURING  
THE NEXT COUPLE OF DAYS. HOWEVER, THE ATMOSPHERE WILL REMAIN DRY  
AND STABLE. RELATIVE HUMIDITY WILL BE MODERATELY LOW DURING THE  
DAY, WITH MAINLY GOOD TO EXCELLENT RECOVERY AT NIGHT. WINDS WILL  
BE MOSTLY DIURNALLY TERRAIN DRIVEN, BUT THEY MAY BECOME LOCALLY  
BREEZY THROUGH THE CASCADE GAPS, PASSES, THE COLUMBIA GORGE AND  
THE RIDGE TOPS.  
 
***WINDS ARE 20 FOOT 10 MINUTE AVERAGES***  
***CWR-CHANCE OF WETTING RAIN 0.10 OR GREATER***
