...LIGHT PRECIP FAR NW CA AND SRN OR FRI-SAT...
...DRY AND WARMER LATER SAT THROUGH FIRST HALF OF NEXT WEEK...

.METEOROLOGICAL CONDITIONS (THU AM - WED AM)...

Showers have ended over far northern CA/southern OR this morning as 
a weak front dissipates over the region.  For Fri, expect a more 
impressive system with an upper jet and extensive moisture plume 
peaking around 1.7" PW near the coast to affect the Pac NW and clip 
far northern CA.  Expect light precip across far NW CA into southern 
OR, possibly moderate at times in the southern OR Cascades. Light 
post-frontal showers are expected to linger into Sat morning. Expect 
freezing levels to generally remain above 10,000 ft through the 
duration of precip.  Totals 0.1-0.25" are expected in extreme NW CA, 
with up to 0.25-0.6" in the southern OR Cascades.

According to models, strong high pressure aloft is expected to 
affect the region later in the weekend through all of next week. 
Expect dry conditions and temperatures well above normal through 
much of the period.
