...SOME LINGERING PRECIP NORTHERN AREAS THIS MORNING...
...BECOMING WARMER AND MAINLY DRY INTO THE UPCOMING WEEKEND...

.METEOROLOGICAL CONDITIONS (TUE AM - MON AM)...

The s/wv trof traversing the Pacific Northwest yesterday...bringing 
light to locally moderate precip to areas mainly north of I-80...is 
now swinging farther inland toward the northern Rockies this 
morning. A few lingering showers are possible across far northern CA 
and northern NV this morning. Otherwise...a secondary disturbance 
making its way through the overall flow will move from the Gulf of 
Alaska toward Vancouver Island today before shifting eastward across 
WA on its way toward the northern Rockies tomorrow. Precip 
associated with this feature will remain north of the region as high 
pressure over the eastern Pacific begins to build closer to the CA 
coast. 

Look for this area of high pressure to dominate conditions through 
the upcoming weekend as it becomes anchored over the eastern 
Pacific. Disturbances will drop southward through the interior of 
western Canada toward the interior of the western US. Enough 
moisture and instability may be present under this flow regime to 
generate some scattered showers over the southern Sierra...southeast 
CA...and southern NV.

Freezing levels currently range from 9000-feet over the upper 
Klamath River basin to 16500-feet along the southern CA coast. As 
high pressure builds across the area...these will generally settle 
and fluctuate near 14000- to 17000-feet across the area from 
northeast to southwest.
