...WARM AND DRY TO START THE WEEK...
...LIGHT PRECIP POSSIBLE NEAR THE CA/OR BORDER LATE FRI/EARLY SAT...

.METEOROLOGICAL CONDITIONS (SUN AM - SAT AM)...

A high pressure ridge aloft continues to be situated offshore over 
the eastern Pacific along 140W. This stagnant pattern has resulted 
in above normal temperatures during the afternoon with dry 
conditions throughout. By the middle of the week...a s/wv trof will 
move across the Pacific Northwest on its way toward the northern and 
central Rockies. Overall...precip will remain north of the CA/OR 
border. However...the upr ridge will slightly shift a bit to the 
west. This will open the door for a stronger s/wv trof to move 
toward the Pacific Northwest on Friday and track a bit closer to the 
area as it makes its way toward the Great Basin. The models are 
hinting at the possibility of some rather light precip near the 
CA/OR border late Friday or early Saturday and portions of northern 
NV for the upcoming weekend. Above normal afternoon high 
temperatures will finally drop closer to or below normal by next 
weekend.
